Description
本發明是關於壓鑄(die casting)用的鋁合金用熱室鑄造機(hot chamber casting machine)及使用鋁合金用熱室鑄造機的壓鑄方法。特別是與本發明有關的鋁合金用熱室鑄造機為迴避習知的熱室鑄造機所具有的問題點,在習知的熱室鑄造機中被視為不適合,關於使用冷室鑄造機(cold chamber casting machine)的鑄造領域也能利用的熱室鑄造機。The present invention relates to a hot chamber casting machine for aluminum alloy for die casting and a die casting method for using a hot chamber casting machine for aluminum alloy. In particular, the hot chamber casting machine for aluminum alloy according to the present invention is a problem in avoiding the conventional hot chamber casting machine, and is considered unsuitable in the conventional hot chamber casting machine, regarding the use of a cold chamber casting machine ( Cold chamber casting machine) can also be utilized in the field of casting.
對製品或零件進行造形的方法係將熔化的金屬澆注到模具得到必要的形狀的方法稱為鑄造,以該製造方法製作的製品稱為[鑄件(casting)]。 鑄造之中壓鑄為對模具(壓鑄模(die))藉由活塞(piston)以規定壓力對熔化的金屬(熔態金屬(molten metal))進行壓入射出(鑄造(cast))的製造方法。 壓鑄機(die casting machine)大致區分的話被分類成熱室鑄造機與冷室鑄造機。熱室鑄造機、冷室鑄造機都是將壓鑄用的金屬材料熔融,將熔態金屬狀態的金屬材料射出到成形模具進行鑄造。The method of forming the article or part by casting the molten metal into the mold to obtain the necessary shape is called casting, and the article produced by the manufacturing method is called [casting]. Die casting is a manufacturing method in which a molten metal (molten metal) is injected (cast) by a piston at a predetermined pressure in a mold (die). The die casting machines are classified into a hot chamber casting machine and a cold chamber casting machine when they are roughly distinguished. Both the hot chamber casting machine and the cold chamber casting machine melt the metal material for die casting, and eject the molten metal metal material into the forming mold for casting.
首先,說明習知的熱室鑄造機。 熱室鑄造機為熔解爐(melting furnace)與鑄造機成一體,活塞式液壓缸(piston-cylinder)射出部及導入管位於熔解爐的熔態金屬中,一起被加熱因此被稱為熱室鑄造機。熔態金屬被由沉到熔解爐的熔態金屬中的活塞式液壓缸射出部擠出,通過導入管,到達模具而被鑄造。First, a conventional hot chamber casting machine will be described. The hot chamber casting machine is a melting furnace integrated with the casting machine. The piston-cylinder injection portion and the introduction tube are located in the molten metal of the melting furnace and are heated together, so it is called hot chamber casting. machine. The molten metal is extruded from a piston-type hydraulic cylinder injection portion that has been deposited in the molten metal of the melting furnace, and is introduced into the mold through the introduction pipe to be cast.
圖6是顯示習知的熱室鑄造機的基本構成之圖。 如圖6所示,熱室鑄造機10係對熔解爐11收納有活塞式液壓缸射出部12,內部以熔態金屬填滿。活塞13被連接驅動於活塞驅動機構(未圖示)。在活塞式液壓缸射出部12的側面設有熔態金屬吸入口14,而且由活塞式液壓缸射出部12的端部導引出射出路徑15。在射出路徑15的頂端附近隔著噴嘴(nozzle)16在熔解爐11之外設置有模具17。此外,射出路徑15的噴嘴16的頂端的高度配設成比熔解爐11內的熔態金屬面的高度高的位置。Fig. 6 is a view showing the basic configuration of a conventional hot chamber casting machine. As shown in FIG. 6, the hot chamber casting machine 10 houses the piston type hydraulic cylinder injection part 12 in the melting furnace 11, and the inside is filled with a molten metal. The piston 13 is connected to a piston drive mechanism (not shown). A molten metal suction port 14 is provided on the side surface of the piston type hydraulic cylinder injection portion 12, and the injection path 15 is guided by the end portion of the piston type hydraulic cylinder injection portion 12. A mold 17 is provided outside the melting furnace 11 via a nozzle 16 in the vicinity of the tip end of the injection path 15. Further, the height of the tip end of the nozzle 16 of the injection path 15 is set to be higher than the height of the molten metal surface in the melting furnace 11.
圖6所示的習知的熱室鑄造機10的鑄造製程是以如下的程序進行。藉由活塞式液壓缸射出部12的活塞13的緊壓,活塞式液壓缸射出部12內的熔態金屬被擠出。活塞的緊壓以10MPa到30MPa的壓力為慣例。例如壓力藉由未圖示的油壓機及/或線性馬達(linear motor)施加於活塞而使其產生。成為藉由活塞的緊壓使熔態金屬由液壓缸內注入到射出路徑15,經由噴嘴16射出到模具17的構造。模具17分離而內部的成形完了的製品被取出。也有伴隨活塞13的上升,空氣自噴嘴16、射出路徑15開始逆流的情形,活塞13的頂端一由熔態金屬吸入口14到達上部,這次熔解爐11中的熔態金屬就由熔態金屬吸入口14流入活塞式液壓缸射出部12。此外,由於噴嘴16的頂端的高度比熔解爐11的熔態金屬面的高度高,因此由熔態金屬吸入口14流入的熔態金屬不會自噴嘴16溢出,熔態金屬被填滿至活塞13的緊壓面的高度。The casting process of the conventional hot chamber casting machine 10 shown in Fig. 6 is carried out in the following procedure. The molten metal in the piston type cylinder injection portion 12 is extruded by the pressing of the piston 13 of the piston type hydraulic cylinder injection portion 12. The pressing of the piston is conventionally carried out at a pressure of 10 MPa to 30 MPa. For example, the pressure is applied to the piston by a hydraulic press and/or a linear motor (not shown). The molten metal is injected into the injection path 15 from the hydraulic cylinder by the pressing of the piston, and is emitted to the mold 17 via the nozzle 16. The mold 17 is separated and the internally formed product is taken out. There is also a case where the air starts to flow back from the nozzle 16 and the injection path 15 with the rise of the piston 13, and the tip end of the piston 13 reaches the upper portion by the molten metal suction port 14, and the molten metal in the melting furnace 11 is sucked by the molten metal. The port 14 flows into the piston type hydraulic cylinder injection portion 12. Further, since the height of the tip end of the nozzle 16 is higher than the height of the molten metal surface of the melting furnace 11, the molten metal flowing in from the molten metal suction port 14 does not overflow from the nozzle 16, and the molten metal is filled up to the piston. The height of the pressing surface of 13.
熔態金屬注入部分位於熔解爐內部的鑄造機有與上述基本構成不同之構成者。例如有揭示於日本國特開2004-122134號公報者。 作為記載於圖6的熱室鑄造機10的特徵有如下的點:由於熔態金屬之供給至活塞式液壓缸射出部12的程序可伴隨著在熔解爐11中的活塞式液壓缸射出部12的活塞作用(piston action)而自動地進行,因此與冷室鑄造機比較,鑄造週期快。The casting machine in which the molten metal injection portion is located inside the melting furnace has a constitution different from the above-described basic configuration. For example, it is disclosed in Japanese Laid-Open Patent Publication No. 2004-122134. The hot chamber casting machine 10 described in FIG. 6 is characterized in that the program for supplying the molten metal to the piston type hydraulic cylinder injection portion 12 can be accompanied by the piston type hydraulic cylinder injection portion 12 in the melting furnace 11. The piston action is performed automatically, so the casting cycle is faster compared to the cold chamber casting machine.
而且,在圖6所示的熱室鑄造機中有如下的點:由於成為壓鑄的路徑的活塞式液壓缸射出部12位於熔態金屬中,因此無來自外部的空氣的捲入。若空氣進入的話則氣孔(blow hole)進入壓鑄製品中而在製品發生不良狀況,惟若是熱室鑄造機10則空氣不會進入活塞式液壓缸射出部12內,因此很少發生氣孔進入壓鑄製品中之不良狀況。 再者也有如下的點:與冷室鑄造機比較,由於射出壓力低即可,因此不施加瞬間負載(transient load)給模具17。Further, in the hot chamber casting machine shown in Fig. 6, there is a point that since the piston type hydraulic cylinder injection portion 12 which is the path of the die casting is located in the molten metal, there is no entrapment of air from the outside. If air enters, the blow hole enters the die-cast product and the product is in a bad condition. However, if the hot chamber casting machine 10 does not enter the piston-type hydraulic cylinder injection portion 12, the pores rarely enter the die-cast product. Bad condition in the middle. Further, there is also a point that since the injection pressure is low as compared with the cold chamber casting machine, no transient load is applied to the mold 17.
其次,說明習知技術中的冷室鑄造機。冷室鑄造機是熔解爐與鑄造機分開,由熔解爐汲出1注料量(shot)份的熔態金屬並將熔態金屬放入位於熔解爐之外的鑄造機,在熔解爐之外進行鑄造。鑄造機係不配設於熔解爐中而配設在外面,不被加熱因此被稱為冷室鑄造機。Next, a cold chamber casting machine in the prior art will be described. The cold chamber casting machine separates the melting furnace from the casting machine, and takes 1 shot of the molten metal from the melting furnace and places the molten metal into a casting machine outside the melting furnace, and performs the outside of the melting furnace. Casting. The casting machine is not disposed in the melting furnace and is disposed outside, and is not heated, so it is called a cold chamber casting machine.
圖7是顯示習知的冷室鑄造機20的基本構成之圖。 如圖7所示,冷室鑄造機20係在熔解爐21之外配設有由套筒(sleeve)22與柱塞(plunger)23構成的擠壓成形機(extruder)24,成為在柱塞23連接有緊壓裝置27而運轉的構造。在套筒22的頂端設置有模具25。而且,有自熔解爐21汲出熔態金屬的澆斗(ladle)26。Fig. 7 is a view showing the basic configuration of a conventional cold chamber casting machine 20. As shown in Fig. 7, in the cold chamber casting machine 20, an extruder 24 composed of a sleeve 22 and a plunger 23 is disposed outside the melting furnace 21 to become a plunger. 23 is a structure in which the pressing device 27 is connected and operated. A mold 25 is provided at the top end of the sleeve 22. Further, there is a ladder (ladle) 26 from which the molten metal is extracted from the melting furnace 21.
圖7所示的習知的冷室鑄造機20的鑄造製程是以如下的程序進行。如圖7(a)所示,藉由澆斗26汲出熔解爐21中的熔態金屬,將1注料量份的熔態金屬注入套筒22。接著如圖7(b)所示,在將規定量的熔態金屬注入套筒22後,藉由柱塞23壓入並塞進模具25而成形。柱塞23的緊壓以60MPa到100MPa的壓力為慣例。例如壓力藉由未圖示的油壓機及/或線性馬達施加於柱塞23而使其產生。The casting process of the conventional cold chamber casting machine 20 shown in Fig. 7 is carried out in the following procedure. As shown in Fig. 7(a), the molten metal in the melting furnace 21 is taken out by the bucket 26, and a molten metal of a shot amount is injected into the sleeve 22. Next, as shown in FIG. 7(b), after a predetermined amount of molten metal is injected into the sleeve 22, it is formed by press-fitting the plunger 23 and inserting it into the mold 25. The pressing of the plunger 23 is conventionally carried out at a pressure of 60 MPa to 100 MPa. For example, the pressure is applied to the plunger 23 by a hydraulic press and/or a linear motor (not shown).
此處,冷室鑄造機20的特徵有如下的點:可對應使用熔點高的金屬原料的壓鑄。即使是使用鋁合金或銅合金等熔點高的金屬原料的情形,圖7所示的冷室鑄造機20由於熔解爐21與鑄造機之擠壓成形機24分開,因此擠壓成形機24無須暴露於熔解爐21的高溫,無該等零件熔損之虞。因此使用像熔點高的金屬原料或鋁合金熔態金屬使鑄造機的零件熔損的材料的壓鑄為可能。Here, the cold chamber casting machine 20 is characterized in that it can be used for die casting of a metal material having a high melting point. Even in the case of using a metal material having a high melting point such as an aluminum alloy or a copper alloy, the cold chamber casting machine 20 shown in Fig. 7 is separated from the extruder 24 of the casting machine, so that the extrusion molding machine 24 does not need to be exposed. At the high temperature of the melting furnace 21, there is no flaw in the melting of the parts. Therefore, it is possible to die-cast a material which melts the parts of the casting machine using a metal material having a high melting point or a molten metal of an aluminum alloy.
而且,冷室鑄造機20的其他的特徵有如下的點:容易對應使用大型的模具的大的東西的製品的成形。進行大的東西的成形此點鑄造機本身變大,但若是像熱室方式般為在熔解爐中收納有鑄造機構之機構的話,則熔解爐變成非常大。此點若為冷室壓鑄的話,則因熔解爐與鑄造機分開,因此可抑制熔解爐的大小。Further, another feature of the cold chamber casting machine 20 is that it is easy to form a product corresponding to a large one using a large mold. In the case of forming a large thing, the casting machine itself becomes large. However, if the mechanism of the casting mechanism is accommodated in the melting furnace like the hot chamber method, the melting furnace becomes very large. If this is a cold chamber die casting, since the melting furnace is separated from the casting machine, the size of the melting furnace can be suppressed.
[專利文獻1] 日本國特開2004-122134號公報[Patent Document 1] Japanese Patent Laid-Open Publication No. 2004-122134
在習知的冷室鑄造機20有缺點。 首先,在習知的冷室鑄造機20中有鑄造速度比較慢的問題。在習知的冷室鑄造機20中需自熔解爐21以澆斗26汲出並注入到套筒22的作業。而且,為了確實地抽出後述的空氣需慎重慢慢地進行柱塞23的塞進。因此發生鑄造時間變長的問題。There are disadvantages in the conventional cold chamber casting machine 20. First, in the conventional cold chamber casting machine 20, there is a problem that the casting speed is relatively slow. In the conventional cold chamber casting machine 20, the operation from the melting furnace 21 by the pouring bucket 26 and injection into the sleeve 22 is required. Further, in order to surely extract the air to be described later, it is necessary to carefully and slowly insert the plunger 23. Therefore, the problem of a long casting time occurs.
其次,在習知的冷室鑄造機20中有空氣混入壓鑄製品中並發生氣孔進入的不良狀況之虞。習知的冷室鑄造機20由於擠壓成形機24被設置於空氣中,因此無論如何空氣也容易混入套筒22中,空氣容易混合於所注入的熔態金屬中。若空氣混入熔態金屬則在模具25內進行壓鑄的結果,成為在鑄造製品中產生氣包氣孔進入的結果。因此真空鑄造法(vacuum casting method)或PF法(無孔法:pore-free method)等對製品的氣孔的對策被訂立,但都很煩雜。Next, in the conventional cold chamber casting machine 20, there is a problem that air is mixed into the die-cast product and the pores enter. Since the conventional cold chamber casting machine 20 is installed in the air in the extrusion molding machine 24, the air is easily mixed into the sleeve 22 anyway, and the air is easily mixed in the molten metal to be injected. If air is mixed into the molten metal, the result of die casting in the mold 25 results in the entry of air pockets in the cast product. Therefore, countermeasures against the pores of the product, such as a vacuum casting method or a PF method (pore-free method), are made, but they are very complicated.
其次,在習知的冷室鑄造機20中有在所成形的鑄造製品的內部發生金屬的破裂之虞。在習知的冷室鑄造機20中由於擠壓成形機24被設置於空氣中,因此容易被散熱、冷卻,在藉由柱塞23擠壓後殘留於套筒22內的鋁合金殘渣冷卻且有時候小的塊片會形成於套筒壁面或角部,而可能在與接下來的壓鑄中被澆注的熔態金屬完全一體化前藉由柱塞23擠壓且被壓鑄到模具。因此有在小的塊片混入的狀態下鑄造製品被製作了的問題。而且,通常因套筒22的溫度比鋁合金的熔點低,因此在藉由澆斗26將鋁合金熔態金屬供給至套筒22時鋁合金熔態金屬一部分凝固,在固形物成分混入熔態金屬的狀態下被送至模具,在該固形物成分散佈於製品中的狀態下進行成形。稱此為通常裂斷冷硬層,使製品強度不穩定。 如上述在冷室鑄造機有缺點,特別是若注視其鑄造速度快與鑄造壓力低的話,則可以說熱室鑄造機為較優良的方式。Next, in the conventional cold chamber casting machine 20, there is a possibility that cracking of the metal occurs inside the formed cast product. In the conventional cold chamber casting machine 20, since the extrusion molding machine 24 is installed in the air, it is easily dissipated and cooled, and the aluminum alloy residue remaining in the sleeve 22 after being pressed by the plunger 23 is cooled and Sometimes small pieces may be formed on the wall or corner of the sleeve and may be pressed by the plunger 23 and die cast into the mold before being fully integrated with the molten metal being cast in the subsequent die casting. Therefore, there is a problem that a cast product is produced in a state in which small pieces are mixed. Further, since the temperature of the sleeve 22 is lower than the melting point of the aluminum alloy, a part of the molten metal of the aluminum alloy is solidified when the molten metal of the aluminum alloy is supplied to the sleeve 22 by the bucket 26, and the solid content is mixed into the molten state. In the state of the metal, it is sent to a mold, and the solid matter is molded in a state of being dispersed in the product. This is called a normally broken chill layer, which makes the strength of the product unstable. As described above, there are disadvantages in the cold chamber casting machine, and in particular, if the casting speed is high and the casting pressure is low, it can be said that the hot chamber casting machine is a more excellent method.
但是,在習知的熱室鑄造機10有大的缺點。 該缺點為在習知的熱室鑄造機10中有無法使用鋁合金的問題。假如以熔解爐熔解鋁合金的話,則因熔解爐11、活塞式液壓缸射出部12、噴嘴16等以鐵系合金做出,因此,會受到鋁合金所造成的熔損,會熔解於鋁合金中而失去本來的功能。不限於鐵系合金,幾乎所有的金屬都會受到鋁合金的侵蝕(erosion),即使藉由氮化、熔射(thermal spraying)等保護也無法得到能滿足的結果。 因此,對熱室鑄造機加以改良,使用鋁合金也能進行鑄造之耐實用的熱室鑄造機被要求。However, the conventional hot chamber casting machine 10 has major drawbacks. This disadvantage is a problem in the conventional hot chamber casting machine 10 in which an aluminum alloy cannot be used. If the aluminum alloy is melted in a melting furnace, the melting furnace 11, the piston cylinder injection portion 12, the nozzle 16, and the like are made of an iron-based alloy, and therefore, the aluminum alloy is melted and melted in the aluminum alloy. Lost the original function. Not limited to iron-based alloys, almost all metals are eroded by aluminum alloys, and satisfactory results cannot be obtained even by protection such as nitriding, thermal spraying, and the like. Therefore, it has been demanded to improve the hot chamber casting machine and to use a heat-resistant chamber casting machine which can be cast using an aluminum alloy.
此處,已知有與圖6的基本構造不同的改良型的砂型低壓鑄造機(sand low pressure casting machine)。成為取代活塞方式的活塞式液壓缸射出部12使用氣壓擠壓熔態金屬的方式。而且,為僅藉由在熔解爐中豎起升液管(stalk)的筒體將成為射出路徑的部分的大部分配設於熔解爐之上的構造。Here, an improved sand low pressure casting machine different from the basic structure of Fig. 6 is known. The piston type hydraulic cylinder injection part 12 which replaces the piston type is a method of extruding a molten metal using air pressure. Further, it is a structure in which most of the portion which is the injection path is disposed on the melting furnace only by the cylinder in which the stalk is erected in the melting furnace.
圖8是日本國特開2004-122134號公報所揭示的砂型低壓鑄造機。此外,圖中的符號是原封不動地使用在日本國特開2004-122134號公報的圖中所使用的符號,與本說明書中的其他的符號無關。Fig. 8 is a sand type low pressure casting machine disclosed in Japanese Laid-Open Patent Publication No. 2004-122134. In addition, the symbols used in the drawings are the symbols used in the drawings of Japanese Laid-Open Patent Publication No. 2004-122134, and are not related to other symbols in the present specification.
如圖8所示,該製造裝置是在爐本體1的內部配設有儲存輕金屬熔態金屬2的熔解爐3。在爐本體1配設有將熔解爐3加熱的氣體燃燒器(gas burner)等的加熱裝置8。在該爐本體1的上方配設有承載砂型11的模置台12。熔解爐3藉由蓋構件4密閉上部,在蓋構件4形成有以低壓將加壓氣體5供給至熔解爐3的內部之加壓氣體供給口6。在該加壓氣體供給口6連接有加壓氣體供給手段7。在熔態金屬中豎起升液管21,進而隔著上方的熔態金屬槽29豎起升液管33,連接於砂型11。而且,配設有熔態金屬面感測器34。As shown in Fig. 8, the manufacturing apparatus is provided with a melting furnace 3 for storing a molten metal molten metal 2 inside the furnace body 1. A heating device 8 such as a gas burner that heats the melting furnace 3 is disposed in the furnace body 1. A mold table 12 carrying a sand mold 11 is disposed above the furnace body 1. In the melting furnace 3, the upper portion is sealed by the lid member 4, and the lid member 4 is formed with a pressurized gas supply port 6 for supplying the pressurized gas 5 to the inside of the melting furnace 3 at a low pressure. A pressurized gas supply means 7 is connected to the pressurized gas supply port 6. The riser pipe 21 is erected in the molten metal, and the riser pipe 33 is erected via the upper molten metal groove 29, and is connected to the sand mold 11. Further, a molten metal surface sensor 34 is provided.
鑄造製程首先以抗氧化氣體或防止燃燒用氣體28將砂型11內的模腔16內的空氣置換成升液管21內的抗氧化氣體或防止燃燒用氣體28。接著,藉由加壓氣體5以低壓將壓力施加至儲存於熔解爐3的輕金屬熔態金屬2的熔液面,經由豎立於熔態金屬的升液管21,通過成為熔態金屬槽的室(chamber)29,進而通過升液管33,將輕金屬熔態金屬2往上推到砂型11的模腔16。在模腔16內填充有輕金屬熔態金屬2的話,在原封不動的狀態下使模腔16內的輕金屬熔態金屬2凝固。 如此,使用由加壓氣體供給手段7產生的加壓氣體5將熔解爐3中的熔態金屬往上推而塞進鑄模(mold),成為不使用像活塞的機構系的裝置。The casting process first replaces the air in the cavity 16 in the sand mold 11 with the antioxidant gas or the combustion preventing gas 28 into the oxidation resistant gas or the combustion preventing gas 28 in the riser pipe 21. Next, pressure is applied to the molten metal surface of the light metal molten metal 2 stored in the melting furnace 3 at a low pressure by the pressurized gas 5, through the riser 21 erected in the molten metal, through the chamber which becomes the molten metal tank. (chamber) 29, and further, the light metal molten metal 2 is pushed up to the cavity 16 of the sand mold 11 through the riser pipe 33. When the cavity 16 is filled with the light metal molten metal 2, the light metal molten metal 2 in the cavity 16 is solidified in the original state. As described above, the molten metal in the melting furnace 3 is pushed up by the pressurized gas 5 generated by the pressurized gas supply means 7, and is inserted into a mold, thereby becoming a mechanism that does not use a mechanism like a piston.
但是,在圖8所記載的砂型低壓鑄造機也有應解決的問題。 首先,在圖8所記載的砂型低壓鑄造機中為了處理鋁合金的金屬材料仍不充分。射出路徑的零件的大部分因不在熔解爐中,因此成為容易散熱的構造,而熔態金屬為高溫,升液管21、熔態金屬槽29、升液管33等的金屬零件暴露於高溫的鋁合金此點毫無改變,依然發生熔損的問題。However, the sand type low pressure casting machine shown in Fig. 8 also has a problem to be solved. First, in the sand type low pressure casting machine shown in Fig. 8, the metal material for treating the aluminum alloy is still insufficient. Most of the parts of the injection path are not in the melting furnace, so they are easy to dissipate heat, and the molten metal is high temperature, and the metal parts such as the liquid ejecting tube 21, the molten metal tank 29, and the liquid elevating tube 33 are exposed to high temperature. The aluminum alloy has not changed at this point, and the problem of melt loss still occurs.
其次,在圖8所記載的砂型低壓鑄造機中在鑄造速度此點有問題。在圖8所示的構造中,因需在砂型低壓鑄造法中將壓力施加至大的熔解爐的熔態金屬的液面全體並將熔態金屬舉起預先保持於熔解爐中的熔態金屬槽29,因此壓力控制困難,需慎重地施加壓力而調整熔態金屬的液面高度,故有鑄造週期比圖6的基本形慢的問題。因此一邊藉由熔態金屬面感測器34感測熔態金屬面的上升位置一邊進行,慎重地被進行。而且,將熔態金屬填滿於砂型11時,由於將壓力施加至大的熔解爐的熔態金屬的液面全體並將熔態金屬注入到砂型11內,因此施加於熔解爐的熔態金屬的液面全體的壓力控制依然困難。因此,加壓需慎重地進行。由於本來在熱室鑄造機中能以對應活塞週期以單發(one shot)打入的方式進行壓鑄,因此在鑄造速度此點有問題。 為了以單發高速打入使得壓鑄成為高壓的氣壓擠壓方式,而壓力非常高也成為10MPa~30MPa。若這點壓力高的話則施加於主筒的應力也相差太大,因應力造成的晃動變大,有因左右的晃動而使主筒破裂的問題。Next, in the sand type low pressure casting machine shown in Fig. 8, there is a problem in the casting speed. In the configuration shown in Fig. 8, the pressure is applied to the liquid level of the molten metal of the large melting furnace in the sand type low pressure casting method, and the molten metal is lifted to the molten metal previously held in the melting furnace. Since the groove 29 is difficult to control the pressure, it is necessary to carefully apply pressure to adjust the liquid level of the molten metal, so that the casting cycle is slower than the basic shape of Fig. 6. Therefore, while the molten metal surface sensor 34 senses the rising position of the molten metal surface, it is performed cautiously. Further, when the molten metal is filled in the sand mold 11, the molten metal applied to the melting furnace is applied because the pressure is applied to the entire liquid surface of the molten metal of the large melting furnace and the molten metal is injected into the sand mold 11. The pressure control of the entire liquid level is still difficult. Therefore, the pressurization needs to be carried out cautiously. Since the die casting machine can be die-cast in a one shot at a corresponding piston cycle, there is a problem in the casting speed. In order to drive at a single high speed, the die casting is a high pressure air pressure extrusion method, and the pressure is very high, and it is also 10 MPa to 30 MPa. If the pressure is high, the stress applied to the main cylinder also differs too much, and the sway due to the stress becomes large, and there is a problem that the main cylinder is broken due to the swaying of the right and left.
因此,鑒於上述問題本發明其目的為藉由改良熱室鑄造機,提供一種鑄造速度快,即使使用鋁合金的熔態金屬也不發生熔損的問題之鋁合金用的熱室鑄造機。Therefore, in view of the above problems, an object of the present invention is to provide a hot chamber casting machine for an aluminum alloy which has a high casting speed and which does not cause melt loss even if a molten metal of an aluminum alloy is used, by improving the hot chamber casting machine.
為了達成上述目的,本發明的鋁合金用熱室鑄造機,其特徵包含:注入熔態金屬之熔解爐;立設於熔解爐內之藉由陶瓷(ceramic)形成的熔態金屬射出主筒部;設於熔態金屬射出主筒部的側面之射出路徑;配設於射出路徑的頂端,將熔態金屬壓鑄到模具之噴嘴;在熔態金屬射出主筒部中,配設於比射出路徑低的位置,開閉熔解爐內與熔態金屬射出主筒部的內部空間的導通之閥體;對熔態金屬射出主筒部的內部空間控制規定壓力的氣壓的施加及除去之加壓部,加壓部一對熔態金屬射出主筒部的內部空間施加氣壓,閥體就作用於被關閉的方向,熔態金屬射出主筒部的內部的熔態金屬由射出路徑被壓鑄到模具,加壓部一對熔態金屬射出主筒部的內部空間除去氣壓,閥體就作用於被開啟的方向,由熔解爐內下次的壓鑄必要的量的熔態金屬被供給至熔態金屬射出主筒部的內部。In order to achieve the above object, a hot chamber casting machine for an aluminum alloy according to the present invention comprises: a melting furnace for injecting a molten metal; and a molten metal formed by a ceramic (ceramic) which is erected in the melting furnace to emit a main cylindrical portion. And an emission path provided on a side surface of the molten metal to eject the main cylindrical portion; a tip end disposed at the tip of the emission path to die-cast the molten metal to the nozzle of the mold; and a molten metal ejection main tube portion disposed in the specific emission path a valve body that opens and closes the inside of the melting furnace and the molten metal to emit the internal space of the main tubular portion; and the pressurized portion that controls the application and removal of the air pressure of the predetermined pressure in the internal space of the molten metal. In the pressurizing portion, a pair of molten metal is injected into the inner space of the main tubular portion to apply air pressure, and the valve body acts on the closed direction, and the molten metal in which the molten metal is emitted from the inside of the main tubular portion is die-cast into the mold by the injection path. A pair of molten metal is pressed out of the inner space of the main tubular portion to remove the air pressure, and the valve body acts on the opened direction, and the molten metal of the necessary amount of the next die casting in the melting furnace is supplied to the molten metal. The internal cylindrical portion.
藉由上述構成,在本發明的鋁合金用熱室鑄造機中,由於配設於熔解爐中的構件為陶瓷製的熔態金屬射出主筒部,因此對鋁合金不會熔損。而且,在本發明的鋁合金用熱室鑄造機中,由於僅透過藉由加壓部施加的氣壓緊壓熔態金屬射出主筒部之小的熔液面即可,且僅將熔態金屬壓入即可,因此壓力控制簡單,可加快壓鑄速度。 而且,在習知的活塞式液壓缸方式中在活塞及液壓缸的壁面被要求高的加工精度,其製作花成本,並且在運轉後的維修保養(maintenance)上也需要壁面的畸變(distortion)或耗損等的對策,惟在本發明中因藉由利用氣壓施加壓力至液壓缸內,因此液壓缸內的壁面的畸變或誤差等不成為問題,可得到可降低液壓缸的製作成本,並且運轉後的維修保養也能簡單地辦到之優點。According to the above configuration, in the hot chamber casting machine for an aluminum alloy according to the present invention, since the member disposed in the melting furnace is made of a molten metal made of ceramic, the main cylindrical portion is not melted. Further, in the hot chamber casting machine for an aluminum alloy according to the present invention, it is only necessary to pass the molten metal applied by the pressurizing portion to press the molten metal to eject the small molten metal surface of the main cylindrical portion, and only the molten metal is used. Press in, so the pressure control is simple, and the speed of die casting can be accelerated. Further, in the conventional piston type hydraulic cylinder method, high machining precision is required on the wall surfaces of the piston and the hydraulic cylinder, the cost of production is made, and wall distortion is required in maintenance after operation. In the present invention, since the pressure is applied to the hydraulic cylinder by the air pressure, the distortion or the error of the wall surface in the hydraulic cylinder is not a problem, and the manufacturing cost of the hydraulic cylinder can be reduced and the operation can be performed. After the maintenance can also easily achieve the advantages.
其次,在上述構成中,配設如下的構造而構成較佳:透過設於熔解爐的下部的固定部對熔解爐固定熔態金屬射出主筒部的下方壁面之構造;在熔態金屬射出主筒部的上端設有凸緣(flange),透過設於熔解爐的上部的上部安裝凹部對熔解爐固定熔態金屬射出主筒部上端的凸緣之構造;使配設於熔解爐的上部的氣體加壓部抵接熔態金屬射出主筒部的上端的凸緣並按壓於下方,同時對熔態金屬射出主筒部的內部空間施加氣壓之構造。 可減小施加於熔態金屬射出主筒部的應力,具有防止破裂的功效。In the above configuration, it is preferable to provide a structure in which a fixed portion provided in a lower portion of the melting furnace is fixed to a melting furnace to fix a structure in which a molten metal is emitted from a lower wall surface of the main cylindrical portion, and a molten metal is emitted from the main portion. a flange is provided at an upper end of the tubular portion, and a structure in which a molten metal is injected from a melting furnace to an upper end of the main tubular portion through a top mounting recess provided in an upper portion of the melting furnace; and a flange disposed at an upper portion of the melting furnace is disposed; The gas pressurizing portion is configured such that the molten metal is injected from the flange of the upper end of the main tubular portion and pressed downward, and the molten metal is injected into the internal space of the main tubular portion. It is possible to reduce the stress applied to the molten metal by the molten metal, and has the effect of preventing cracking.
此處,閥體為球閥(ball valve),熔態金屬射出主筒部的下部內表面成研鉢狀以使球閥容易被導通孔導引,以在研鉢狀的壁面的最下部比球閥的直徑小的導通孔開啟而導通至熔解爐內的構造較佳。 若為球閥則可藉由來自上方的壓力確實地關閉,若來自上方的壓力成為負壓,則可確實地開啟。若球閥被設置於導通孔,則可控制熔解爐內的熔態金屬的取出和放入。而且,熔態金屬的供給時也能將與在上次的壓鑄被消耗的熔態金屬相稱的量的熔態金屬供給至下次的壓鑄用。Here, the valve body is a ball valve, and the molten metal is ejected from the lower inner surface of the main tubular portion into a mortar shape so that the ball valve is easily guided by the through hole so as to be at the lowermost portion of the mortar-shaped wall surface than the ball valve. A configuration in which a small diameter via hole is opened to conduct into the melting furnace is preferred. If it is a ball valve, it can be reliably closed by the pressure from the upper side, and if the pressure from the upper side becomes a negative pressure, it can be surely opened. If the ball valve is placed in the through hole, the removal and insertion of the molten metal in the melting furnace can be controlled. Further, when the molten metal is supplied, the molten metal in an amount commensurate with the molten metal consumed in the previous die casting can be supplied to the next die casting.
此外,在熔態金屬射出主筒部的內部空間預先設有使由加壓部藉由氣壓施加而突入的氣體流速減速的氣體減速部較佳。氣流一被強勁有力地打出到熔態金屬射出主筒部之中,就在內部的熔態金屬表面產生飛沫或起波浪,因此,使該突入的氣流減速。例如有配設於對向於氣體導入管的位置的板材、曲折填封(labyrinth)、擋板(damper)等當作氣體減速部。Further, it is preferable that a gas decelerating portion for decelerating the flow velocity of the gas which is caused by the application of the air pressure by the pressurizing portion is provided in advance in the internal space of the molten metal injection main cylinder portion. As soon as the airflow is strongly and strongly injected into the main cylindrical portion of the molten metal, droplets or waves are generated on the inner molten metal surface, thereby decelerating the infiltrated airflow. For example, a plate member, a labyrinth, a damper, or the like disposed at a position facing the gas introduction pipe may be used as the gas deceleration portion.
再者,為了防止在氣壓施加時熔態金屬射出主筒部內部的熔態金屬面的起波浪或熔態金屬的飛散,使鋁合金熔態金屬與空氣接觸產生的固體狀的氧化物,或者比重比鋁合金熔態金屬小,且由不會受到來自鋁合金熔態金屬的熔損的多孔的(porous)的氧化鋁等做出的蓋狀的物體浮起於熔態金屬射出主筒部內部的熔態金屬面較佳。Further, in order to prevent the molten metal from ejecting from the molten metal surface inside the main cylindrical portion or the scattering of the molten metal when the gas is applied, the solid oxide generated by the molten metal of the aluminum alloy is brought into contact with the air, or The lid-like object made of a porous aluminum alloy that is less than the molten metal of the aluminum alloy and which is not subjected to the melting of the molten metal of the aluminum alloy is floated on the molten metal. The inner molten metal surface is preferred.
加壓部的構成以具備氣槽(gas tank)與電磁閥(electromagnetic valve)與氣體導入管而構成較佳。若為電磁閥則開閉動作迅速,可藉由電磁閥的開閉動作正確地控制施加的氣體量。The pressurizing portion is preferably configured to include a gas tank, an electromagnetic valve, and a gas introduction pipe. In the case of a solenoid valve, the opening and closing operation is rapid, and the amount of gas to be applied can be accurately controlled by the opening and closing operation of the solenoid valve.
本發明的鋁合金用熱室鑄造機由於配設於熔解爐中的構件為陶瓷製的熔態金屬射出主筒部、噴嘴、球閥,接觸熔解爐內部的鋁合金的部分是以陶瓷塗料(ceramic coating)塗佈(coating),因此對鋁合金不會熔損,能以鋁合金當作金屬材料使用。 而且,本發明的鋁合金用熱室鑄造機由於僅透過藉由加壓部施加的氣壓緊壓熔態金屬射出主筒部之小的熔液面即可,且僅壓入下方向即可,因此壓力控制簡單,可加快壓鑄速度。 而且,在習知的活塞式液壓缸方式中在活塞及液壓缸的壁面被要求高的加工精度,其製作花成本,並且在運轉後的維修保養上也需要壁面的畸變或耗損等的對策,惟在本發明中因藉由利用氣壓施加壓力至液壓缸內,因此液壓缸內的壁面的畸變或誤差等不成為問題,可得到可降低液壓缸的製作成本,並且運轉後的維修保養也能簡單地辦到之優點。In the hot chamber casting machine for aluminum alloy according to the present invention, the member disposed in the melting furnace is a molten metal of a ceramic, which is injected into the main cylinder portion, the nozzle, and the ball valve, and the portion of the aluminum alloy that contacts the inside of the melting furnace is ceramic paint (ceramic Coating) coating, so that the aluminum alloy is not melted, and the aluminum alloy can be used as a metal material. Further, in the hot chamber casting machine for an aluminum alloy according to the present invention, it is sufficient that the molten metal is pressed through the molten metal by the pressure applied to the molten metal to eject the small molten metal surface of the main tubular portion, and only the downward direction is pressed. Therefore, the pressure control is simple, and the die casting speed can be accelerated. Further, in the conventional piston type hydraulic cylinder system, high machining accuracy is required on the wall surfaces of the piston and the hydraulic cylinder, and the manufacturing cost is required, and the wall surface distortion or wear is also required for maintenance after the operation. However, in the present invention, since the pressure is applied to the hydraulic cylinder by the air pressure, the distortion or error of the wall surface in the hydraulic cylinder is not a problem, and the manufacturing cost of the hydraulic cylinder can be reduced, and the maintenance after the operation can be performed. Simply do it.
以下一邊參照圖面,一邊說明本發明的鋁合金用熱室鑄造機的實施形態。但是本發明的技術範圍不被以下的實施形態所示的具體的用途或形狀、尺寸等限定。 [實施例一]Hereinafter, an embodiment of the hot chamber casting machine for aluminum alloy of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to the specific use, shape, size, and the like shown in the following embodiments. [Example 1]
圖1是簡單地顯示本發明的鋁合金用熱室鑄造機100的構成例之圖。 在圖1中為了使內部的構造容易理解,在縱剖面中顯示各構件。在圖1中為了理解構件的特徵而簡單地進行圖示,僅圖示在理解本發明上必要的構件,關於其他的一部分的構件也有未圖示的情形。Fig. 1 is a view schematically showing a configuration example of a hot chamber casting machine 100 for an aluminum alloy according to the present invention. In Fig. 1, in order to make the internal structure easy to understand, each member is shown in a longitudinal section. In FIG. 1, in order to understand the characteristics of a member, it is simply illustrated, and only the members necessary for understanding the present invention are shown, and the other members are also not shown.
在圖1的構造例中,鋁合金用熱室鑄造機100具備熔解爐110、熔態金屬射出主筒部120、射出路徑130、噴嘴140、閥體150、氣體加壓部160。而且,模具200一併被顯示。In the structural example of FIG. 1 , the hot chamber casting machine 100 for aluminum alloy includes a melting furnace 110 , a molten metal injection main cylinder portion 120 , an injection path 130 , a nozzle 140 , a valve body 150 , and a gas pressurizing unit 160 . Moreover, the mold 200 is displayed together.
熔解爐110配設有加熱裝置111與儲存將金屬材料熔融的熔態金屬之坩堝(crucible)112。在該坩堝112的頂面配設有蓋材113,在其一部分有開口部116,由該開口部116進行因鑄造而消耗的鋁合金材料的供給。在蓋材113設有收納熔態金屬射出主筒部120的上部的上部安裝凹部117。此處熔態金屬是將鋁合金熔解的熔態金屬。 而且,在圖1的構成例中,在熔解爐110的坩堝112設有在內部中於立設狀態下固定熔態金屬射出主筒部120用的固定部114,設有安裝固定部114用的下部安裝凹部118。 而且,配設有用以將射出路徑130導出到模具的噴嘴140。The melting furnace 110 is provided with a heating device 111 and a crucible 112 that stores a molten metal that melts the metal material. A lid member 113 is disposed on the top surface of the crucible 112, and an opening portion 116 is formed in a portion thereof, and the opening portion 116 supplies the aluminum alloy material consumed by the casting. The lid member 113 is provided with an upper mounting recess 117 that accommodates the upper portion of the molten metal injection main tubular portion 120. Here, the molten metal is a molten metal that melts the aluminum alloy. Further, in the configuration example of Fig. 1, the crucible 112 of the melting furnace 110 is provided with a fixing portion 114 for fixing the molten metal to the main tubular portion 120 in the standing state in the interior, and is provided with the mounting fixing portion 114. The lower portion mounts the recess 118. Further, a nozzle 140 for guiding the injection path 130 to the mold is disposed.
固定部114是用以在坩堝112內部穩定固定熔態金屬射出主筒部120的構件,以抵接熔態金屬射出主筒部120的外壁面或構件的形式固定。在圖1的構成例中,在熔態金屬射出主筒部120的上端設有凸緣122,熔態金屬射出主筒部120的上部側係凸緣122嵌入上部安裝凹部117,進而為了氣體加壓部160由上方抵接,以包圍熔態金屬射出主筒部120的凸緣122的側面、頂面的方式被固定。據此可限制熔態金屬射出主筒部120之上部附近中的上方向的移動、朝水平方向的移動。而且,在熔態金屬射出主筒部120的下部立設有下方壁面126,嵌合於下部安裝凹部118的固定部114成為對熔態金屬射出主筒部120的下方壁面126由外方抵接的構件。據此可限制熔態金屬射出主筒部120之下部附近中的下方向的移動、朝水平方向的移動。如此由於藉由固定部114而使熔態金屬射出主筒部120其上部、其下部都被限制上下方向的移動、朝水平方向的移動,因此會被穩定地固定。The fixing portion 114 is a member for stably fixing the molten metal to the main cylindrical portion 120 inside the crucible 112, and is fixed in contact with the outer wall surface or member of the molten metal injection main tubular portion 120. In the configuration example of Fig. 1, a flange 122 is provided at the upper end of the molten metal emission main cylinder portion 120, and the upper side flange 122 of the molten metal injection main cylinder portion 120 is fitted into the upper mounting recess 117, and further, for gas addition. The pressing portion 160 abuts against the upper portion, and is fixed so as to surround the side surface and the top surface of the flange 122 of the molten metal portion of the main tubular portion 120. According to this, it is possible to restrict the movement of the molten metal in the upper direction in the vicinity of the upper portion of the main tubular portion 120 and the movement in the horizontal direction. Further, a lower wall surface 126 is erected on a lower portion of the molten metal emission main tubular portion 120, and the fixing portion 114 fitted to the lower attachment concave portion 118 is externally abutted against the lower wall surface 126 of the molten metal emission main tubular portion 120. Components. According to this, it is possible to restrict the movement of the molten metal in the lower direction in the vicinity of the lower portion of the main tubular portion 120 and the movement in the horizontal direction. In this manner, the molten metal is emitted from the upper portion and the lower portion of the main cylindrical portion 120 by the fixing portion 114 so as to be restricted in the vertical direction and moved in the horizontal direction, so that the molten metal is stably fixed.
熔態金屬射出主筒部120為立設於熔解爐110的坩堝112內的陶瓷製的筒體。作為陶瓷製,製作耐熱性優良的筒體,選擇即使是鋁合金的熔態金屬也不熔損、破損者較佳。 熔態金屬射出主筒部120的形狀不被限定,惟此處是以圖示於圖1的形狀而構成。在圖1的構成例中,凸緣122對呈圓筒形的主筒部分121突出於上端。主筒部分121的內部空間為123。在主筒部分121的底面有成形成研鉢狀的底面部124,在其最下方設有導通孔125。在該導通孔125安裝有控制開閉的閥體150。The molten metal injection main cylinder portion 120 is a ceramic cylinder that is erected in the crucible 112 of the melting furnace 110. As a ceramics, a cylinder having excellent heat resistance is produced, and it is preferable that a molten metal of an aluminum alloy is not melted or damaged. The shape of the molten metal injection main tubular portion 120 is not limited, but is configured here as shown in the shape of FIG. In the configuration example of Fig. 1, the flange 122 protrudes from the upper end of the cylindrical main cylinder portion 121. The internal space of the main cylinder portion 121 is 123. A bottom surface portion 124 formed in a mortar shape is formed on the bottom surface of the main cylinder portion 121, and a through hole 125 is formed at the bottom. A valve body 150 that controls opening and closing is attached to the through hole 125.
在主筒部分121的底面附近立設有將主筒部分121的外壁面延設於下方的下方壁面126,雖然包圍位於主筒部分121的底面下的底部空間127,但在下方壁面126至少在其一部分設有將熔態金屬導入到底部空間127用的開口128。經由該開口128熔態金屬導通於底部空間127。如此透過閥體150的開閉動作使內部空間123與底部空間127的導通/隔絕被控制。A lower wall surface 126 that extends the outer wall surface of the main cylinder portion 121 below is provided in the vicinity of the bottom surface of the main cylinder portion 121, and surrounds the bottom space 127 located below the bottom surface of the main cylinder portion 121, but at least the lower wall surface 126 is at least A portion thereof is provided with an opening 128 for introducing molten metal into the bottom space 127. The molten metal is conducted through the opening 128 to the bottom space 127. Thus, the opening/closing operation of the valve body 150 controls the conduction/isolation of the internal space 123 and the bottom space 127.
而且,在圖1的構成例中,在熔態金屬射出主筒部120的內部空間123的上方附近設有氣體減速部129。該氣體減速部129是使藉由後述的加壓部160的氣壓的施加而由氣體導入管164突入的氣體流速減速的構件。為藉由碰觸氣流而將氣體流速減弱的構造,僅僅是板狀體或擋板、在內部導通管的通道折彎成曲折狀的曲徑管(labyrinth pipe)等構件的構造未被特別限定。藉由設有這種氣體減速部129,使氣流被強勁有力地打出到熔態金屬射出主筒部120之中並突入到熔態金屬表面而產生飛沫或起波浪,可抑制熔態金屬射出主筒部120的損傷等。Further, in the configuration example of FIG. 1, a gas deceleration portion 129 is provided in the vicinity of the upper portion of the internal space 123 of the molten metal emission main tubular portion 120. The gas deceleration unit 129 is a member that decelerates the flow velocity of the gas that is introduced by the gas introduction pipe 164 by the application of the air pressure of the pressurizing unit 160 to be described later. The structure in which the gas flow velocity is weakened by the contact with the air flow is not particularly limited in the configuration of members such as a plate-like body or a baffle plate, and a labyrinth pipe in which the passage of the inner conductive pipe is bent into a meandering shape. . By providing such a gas deceleration portion 129, the airflow is strongly and strongly injected into the molten metal injection main cylinder portion 120 and protrudes into the molten metal surface to generate droplets or waves, thereby suppressing the molten metal from being emitted. Damage to the tubular portion 120 or the like.
射出路徑130是設於熔態金屬射出主筒部120的側面的路徑,與熔態金屬射出主筒部120的內部空間123導通,熔態金屬射出主筒部120的內部空間123藉由加壓部160的氣體施加而被緊壓的熔態金屬通過該射出路徑130而被壓鑄到模具200。The emission path 130 is a path provided on the side surface of the molten metal emission main tube portion 120, and is electrically connected to the internal space 123 of the molten metal emission main tube portion 120, and the molten metal is emitted from the internal space 123 of the main cylindrical portion 120 by pressurization. The molten metal pressed by the gas of the portion 160 is die-cast into the mold 200 through the injection path 130.
噴嘴140是配設於射出路徑130的頂端附近的構件,被連接於模具200。熔態金屬由噴嘴140被壓鑄到模具200內。噴嘴140透過射出路徑導出部115被導引至坩堝112的外部且被連接於模具200。The nozzle 140 is a member disposed near the tip end of the injection path 130 and is connected to the mold 200. The molten metal is die cast into the mold 200 by the nozzle 140. The nozzle 140 is guided to the outside of the crucible 112 through the emission path deriving portion 115 and is connected to the mold 200.
閥體150在熔態金屬射出主筒部120中配設於比射出路徑130低的位置,為將熔解爐110的坩堝112內與熔態金屬射出主筒部120的內部空間123導通開閉的構件。在圖1的構成例中閥體150成為球閥。此外如上述,熔態金屬射出主筒部120的內部空間123的底面部124形成研鉢狀,以使球閥容易被導通孔125導引。導通孔125成為比球閥的直徑小,藉由嵌入球閥而使導通孔125關閉的結構。The valve body 150 is disposed at a position lower than the emission path 130 in the molten metal emission main tube portion 120, and is a member that opens and closes the inside of the crucible 110 of the melting furnace 110 and the internal space 123 of the molten metal emission main tube portion 120. . In the configuration example of Fig. 1, the valve body 150 serves as a ball valve. Further, as described above, the bottom surface portion 124 of the inner space 123 of the molten metal injection main cylinder portion 120 is formed in a mortar shape so that the ball valve is easily guided by the conduction hole 125. The via hole 125 has a structure smaller than the diameter of the ball valve, and the via hole 125 is closed by being embedded in the ball valve.
在閥體150被緊壓的關閉狀態下,熔解爐110的坩堝112與熔態金屬射出主筒部120的內部空間123被隔絕,兩者間的熔態金屬的移動消失。此處由於閥體150配設於比射出路徑130低的位置,因此熔態金屬射出主筒部120的內部空間123與射出路徑130的導通被保持,其結果,在對閥體150由上方施加壓力而使閥體150關閉的狀態下,熔態金屬會朝射出路徑130被導引。In the closed state in which the valve body 150 is pressed, the crucible 112 of the melting furnace 110 and the inner space 123 of the molten metal injection main cylinder portion 120 are isolated, and the movement of the molten metal therebetween disappears. Here, since the valve body 150 is disposed at a position lower than the emission path 130, the conduction between the internal space 123 of the molten metal main pipe portion 120 and the injection path 130 is maintained, and as a result, the valve body 150 is applied upward. In a state where the pressure causes the valve body 150 to be closed, the molten metal is guided toward the injection path 130.
另一方面,在沒有對閥體150緊壓的開啟狀態下,詳細如後述,若藉由電磁閥163的操作而使熔態金屬射出主筒部120的內部空間123成為大氣壓,則施加於閥體150的頂面的壓力由於位於內部空間123的熔態金屬被壓鑄到模具200而消失,因此變小,另一方面,施加於閥體150的底面的壓力由於受到來自坩堝112的熔態金屬的壓力大,因此閥體150就會被推到上方。閥體150一被往上推,在導通孔125與閥體150之間就產生間隙,熔解爐110的坩堝112與熔態金屬射出主筒部120的內部空間123就導通。閥體150一被開啟,熔態金屬就流入內部空間123直到兩者的壓力差消失為止,也就是說,直到熔態金屬射出主筒部120的內部空間123的熔態金屬的頂面略等於坩堝112內的熔態金屬的頂面為止。此外,由於閥體150有重量,因此需考慮閥體150的重量部分的影響。On the other hand, in the open state in which the valve body 150 is not pressed, as will be described later in detail, when the molten metal 163 is operated by the electromagnetic valve 163, the molten metal is emitted into the internal space 123 of the main tubular portion 120 to be atmospheric pressure, and is applied to the valve. The pressure of the top surface of the body 150 disappears due to the molten metal located in the internal space 123 being die-cast into the mold 200, and thus becomes small. On the other hand, the pressure applied to the bottom surface of the valve body 150 is affected by the molten metal from the crucible 112. The pressure is high, so the valve body 150 is pushed up. As soon as the valve body 150 is pushed upward, a gap is formed between the through hole 125 and the valve body 150, and the crucible 112 of the melting furnace 110 and the inner space 123 of the molten metal injection main cylinder portion 120 are electrically connected. As soon as the valve body 150 is opened, the molten metal flows into the internal space 123 until the pressure difference between the two disappears, that is, until the molten metal exits the top surface of the molten metal of the internal space 123 of the main cylindrical portion 120 slightly equal to The top surface of the molten metal in the crucible 112. Further, since the valve body 150 has a weight, it is necessary to consider the influence of the weight portion of the valve body 150.
氣體加壓部160是對熔態金屬射出主筒部120的內部空間123控制規定壓力的氣壓的施加及除去的部分。 在圖1的構成例中,氣體加壓部160成為具備高壓泵(high pressure pump)161、氣槽(gas tank)162、電磁閥163、氣體導入管164、飛散防止蓋165之構成。The gas pressurizing unit 160 is a portion that applies and removes the air pressure that controls the predetermined pressure in the internal space 123 of the molten metal main pipe portion 120. In the configuration example of FIG. 1 , the gas pressurizing unit 160 is configured to include a high pressure pump 161 , a gas tank 162 , a solenoid valve 163 , a gas introduction pipe 164 , and a scattering prevention cover 165 .
高壓泵161是將高壓氣體送入氣槽162內的裝置。氣槽162如後述是為了藉由電磁閥163的開閉對熔態金屬射出主筒部120的內部空間123一鼓作氣地送入高壓的氣體,預先儲存規定壓力的氣體的容器。The high pressure pump 161 is a device that feeds high pressure gas into the gas tank 162. The gas tank 162 is a container for preliminarily storing a gas of a predetermined pressure by blowing a high-pressure gas into the internal space 123 of the molten metal injection main cylinder portion 120 by opening and closing the electromagnetic valve 163.
儲存於氣槽162的氣壓是以在打開電磁閥163時,相當於一般在熱室鑄造機所需的活塞壓力的10MPa到30MPa的氣壓。此處應考慮的點為由於即將開啟電磁閥163之前的熔態金屬射出主筒部120的內部空間123的熔態金屬未填滿的空間僅為大氣壓(約0.1MPa)的壓力,因此打開電磁閥163將氣槽162的氣體導入內部空間123時,內部空間123的大氣壓部分與氣槽162的壓力部分相合而被施加於熔態金屬面。也就是說,當初的氣槽162的儲存部分高的氣壓藉由內部空間123的大氣壓部分而減少且被施加於熔態金屬面,因此氣槽162預先儲存的氣壓在考慮了不是射出所需的壓力(10MPa到30MPa)而是內部空間123的大氣壓部分所造成的減少份後需設定為稍大一些。The gas pressure stored in the gas tank 162 is equivalent to a pressure of 10 MPa to 30 MPa which is generally required for the piston pressure of the hot chamber casting machine when the solenoid valve 163 is opened. The point to be considered here is that the molten metal that is not filled in the inner space 123 of the main cylindrical portion 120 before the solenoid valve 163 is about to be opened is only the pressure of atmospheric pressure (about 0.1 MPa), so the electromagnetic is turned on. When the valve 163 introduces the gas of the gas groove 162 into the internal space 123, the atmospheric pressure portion of the internal space 123 is combined with the pressure portion of the gas groove 162 to be applied to the molten metal surface. That is to say, the high gas pressure of the storage portion of the original gas groove 162 is reduced by the atmospheric pressure portion of the internal space 123 and is applied to the molten metal surface, so that the gas pressure previously stored in the gas groove 162 is considered to be not required for injection. The pressure (10 MPa to 30 MPa) is set to be slightly larger after the reduction of the atmospheric pressure portion of the internal space 123.
電磁閥163以閥快門速度快,可瞬間地進行閥動作者較佳。此處連接於氣槽162側與連接於大氣壓側可被瞬間地切換。電磁閥163與氣槽162連接,電磁閥163一將氣槽162側開啟,氣體導入管164就可立即對熔態金屬射出主筒部120的內部空間123施加10MPa到30MPa的氣壓。另一方面,若電磁閥163將氣槽162側關閉並將大氣壓側開啟,則可使熔態金屬射出主筒部120的內部空間123返回到大氣壓。The solenoid valve 163 has a valve shutter speed, and it is preferable to perform the valve motion instantaneously. Here, the side connected to the gas groove 162 and the side connected to the atmospheric pressure can be switched instantaneously. The solenoid valve 163 is connected to the gas groove 162, and the solenoid valve 163 opens the gas groove 162 side, and the gas introduction pipe 164 can immediately apply a gas pressure of 10 MPa to 30 MPa to the internal space 123 of the molten metal injection main cylinder portion 120. On the other hand, when the solenoid valve 163 closes the gas groove 162 side and opens the atmospheric pressure side, the molten metal can be returned to the atmospheric pressure of the internal space 123 of the main cylindrical portion 120.
飛散防止蓋165是由不會受到來自鋁合金熔態金屬的熔損的多孔的氧化鋁等做出的蓋狀的物體,是藉由預先浮起於熔態金屬射出主筒部內部的熔態金屬面,用以防止在氣壓施加時熔態金屬射出主筒部內部的熔態金屬面的起波浪或熔態金屬的飛散的構件。此外,若是形成有鋁合金熔態金屬與空氣接觸產生的固體狀的氧化物的狀態,則其氧化物可能會成為飛散防止蓋165的替代物。 如上述由於藉由電磁閥163的開閉而導入的氣壓大,因此藉由在熔態金屬射出主筒部的壁面設有氣體減速部129使氣體流速減速,設法進行熔態金屬面的起波浪或熔態金屬的飛散防止,進而預先使飛散防止蓋165浮起於熔態金屬面之上,可確實地防止熔態金屬面的起波浪或熔態金屬的飛散。The scattering prevention cover 165 is a lid-shaped object made of porous alumina or the like which is not subjected to melting loss from the molten metal of the aluminum alloy, and is melted by the molten metal before the molten metal is injected into the main cylindrical portion. The metal surface is a member for preventing scattering of molten metal or molten metal from the molten metal surface inside the main cylindrical portion when the gas is applied. Further, in the state in which a solid oxide formed by contact of an aluminum alloy molten metal with air is formed, the oxide may become a substitute for the scattering prevention cover 165. As described above, since the air pressure introduced by the opening and closing of the electromagnetic valve 163 is large, the gas flow velocity is decelerated by providing the gas deceleration portion 129 on the wall surface of the molten metal injection main cylinder portion, and the molten metal surface is caused to wave or The scattering of the molten metal is prevented, and the scattering prevention cover 165 is floated on the molten metal surface in advance, and the scattering of the molten metal surface or the scattering of the molten metal can be reliably prevented.
以上是圖1所示的本發明的鋁合金用熱室鑄造機的各構件的說明。The above is the description of each member of the hot chamber casting machine for aluminum alloy of the present invention shown in Fig. 1 .
其次,就本發明的鋁合金用熱室鑄造機的動作按照順序進行說明。 首先,說明鑄造週期的第一程序。 圖2是顯示第一程序的初始狀態之圖。如圖2所示,電磁閥163連接於大氣壓側,在熔態金屬射出主筒部120的內部空間123,熔態金屬被填滿相當於由坩堝112內的熔態金屬的高度考慮了閥體150的密度的高度的程度。球閥的閥體150自然地穩定於熔態金屬射出主筒部120的底面部124。熔態金屬為鋁合金,被升溫至規定的溫度,在良好的狀態下成為液體狀態。Next, the operation of the hot chamber casting machine for aluminum alloy of the present invention will be described in order. First, the first procedure of the casting cycle will be explained. Fig. 2 is a diagram showing an initial state of the first program. As shown in FIG. 2, the solenoid valve 163 is connected to the atmospheric pressure side, and the molten metal is injected into the internal space 123 of the main cylindrical portion 120, and the molten metal is filled up to correspond to the height of the molten metal in the crucible 112. The degree of density of 150. The valve body 150 of the ball valve is naturally stabilized by the molten metal exiting the bottom surface portion 124 of the main tubular portion 120. The molten metal is an aluminum alloy, and is heated to a predetermined temperature and is in a liquid state in a good state.
其次,進入第一程序。圖3是顯示鑄造週期的第一程序之圖。如圖3所示,電磁閥163被切換以連接於氣槽162側,一開啟氣槽162側,就經由氣體導入管164立即將與壓鑄所需的10MPa到30MPa的氣壓相稱的壓力的高壓氣體對熔態金屬射出主筒部120的內部空間123施加。其結果,該壓力施加於熔態金屬射出主筒部120的內部空間123的熔態金屬,球閥之閥體150被緊壓至下方且導通孔125被關閉。此處由於熔態金屬射出主筒部120的內部空間123與射出路徑130導通,因此內部空間123的熔態金屬一被緊壓,就由內部空間123朝射出路徑130射出。隔著射出路徑130的前面的噴嘴140設置有模具200,鋁合金的熔態金屬被壓鑄到模具200內。Second, enter the first procedure. Figure 3 is a diagram showing the first procedure of the casting cycle. As shown in FIG. 3, the solenoid valve 163 is switched to be connected to the side of the gas groove 162, and once the gas groove 162 side is opened, the high pressure gas at a pressure commensurate with the pressure of 10 MPa to 30 MPa required for die casting is immediately passed through the gas introduction pipe 164. The molten metal is applied to the internal space 123 of the main tubular portion 120. As a result, the pressure is applied to the molten metal in which the molten metal is ejected from the internal space 123 of the main tubular portion 120, and the valve body 150 of the ball valve is pressed downward and the via hole 125 is closed. Here, since the molten metal is emitted from the inner space 123 of the main tubular portion 120 and the emission path 130, the molten metal of the internal space 123 is pressed, and is emitted from the internal space 123 toward the emission path 130. The mold 200 is disposed through the nozzle 140 on the front side of the injection path 130, and the molten metal of the aluminum alloy is die-cast into the mold 200.
其次,進入第二程序。圖4是顯示鑄造完了的時間點之圖。射出完成而第一程序結束後,切換電磁閥163,使內部空間123成大氣壓。等待規定的時間經過,等待壓鑄成型品冷卻到規定溫度,冷卻後如圖4所示,開啟模具200並取出壓鑄成型品。Second, enter the second program. Fig. 4 is a view showing the time point at which casting is completed. After the completion of the injection and the end of the first program, the solenoid valve 163 is switched to bring the internal space 123 to atmospheric pressure. After waiting for a predetermined period of time, the die-cast molded product is cooled to a predetermined temperature, and after cooling, as shown in FIG. 4, the mold 200 is opened and the die-cast molded article is taken out.
圖5是顯示在第二程序中,正在恢復到圖2的狀態的樣子之圖。如圖5所示,在圖4的鑄造完了的時間點電磁閥163被切換以連接於大氣壓側,氣槽162側的連接一被隔絕,就經由氣體導入管164立即使熔態金屬射出主筒部120的內部空間123成為大氣壓。熔態金屬射出主筒部120的內部空間123的熔態金屬的液面高度為圖3的狀態,也就是說,熔態金屬的液面高度比坩堝112內的熔態金屬的液面的高度低。此處對閥體150由頂面施加的壓力是由大氣壓下的內部空間123的熔態金屬的高度產生的壓力,對閥體150由底面施加的壓力是由坩堝112的熔態金屬的高度產生的壓力。由於在圖3的狀態下內部空間123的熔態金屬的高度比坩堝112的熔態金屬的高度低,因此由閥體150的底面受到的壓力較大。因此閥體150上升,在熔態金屬射出主筒部120的底面部124與閥體150之間產生間隙,導通孔125導通。其結果,坩堝112的熔態金屬對熔態金屬射出主筒部120的內部空間123流入。圖5成為閥體150上升,熔態金屬被供給至熔態金屬射出主筒部120的內部空間123的狀態。若忽視閥體150的重量,則在熔態金屬射出主筒部120的內部空間123的熔態金屬液面成為與坩堝112內的熔態金屬液面相同的高度的時間點停止供給。實際上因閥體150有重量,因此僅閥體150的重量的影響部分而在內部空間123的熔態金屬液面比坩堝112內的熔態金屬液面稍微低的狀態下停止供給。該供給量只要是下次的壓鑄所需的熔態金屬量的話即可。Fig. 5 is a view showing a state in which the state of Fig. 2 is being restored in the second program. As shown in FIG. 5, at the time when the casting of FIG. 4 is completed, the solenoid valve 163 is switched to be connected to the atmospheric pressure side, and the connection on the side of the gas groove 162 is isolated, and the molten metal is immediately ejected from the main cylinder via the gas introduction pipe 164. The internal space 123 of the portion 120 becomes atmospheric pressure. The molten metal exits the molten metal of the inner space 123 of the main cylindrical portion 120 at a liquid level of the state of FIG. 3, that is, the liquid level of the molten metal is higher than the liquid level of the molten metal in the crucible 112. low. Here, the pressure applied to the valve body 150 from the top surface is the pressure generated by the height of the molten metal of the internal space 123 at atmospheric pressure, and the pressure applied to the bottom surface of the valve body 150 is generated by the height of the molten metal of the crucible 112. pressure. Since the height of the molten metal of the internal space 123 is lower than the height of the molten metal of the crucible 112 in the state of FIG. 3, the pressure received by the bottom surface of the valve body 150 is large. Therefore, the valve body 150 ascends, and a gap is formed between the bottom surface portion 124 of the molten metal injection main cylinder portion 120 and the valve body 150, and the conduction hole 125 is electrically connected. As a result, the molten metal of the crucible 112 flows into the internal space 123 of the molten metal exiting the main tubular portion 120. In FIG. 5, the valve body 150 is raised, and the molten metal is supplied to the state in which the molten metal is emitted from the internal space 123 of the main tubular portion 120. When the weight of the valve body 150 is ignored, the supply is stopped when the molten metal surface of the internal space 123 of the molten metal main discharge portion 120 becomes the same height as the molten metal surface in the crucible 112. Actually, since the valve body 150 has a weight, only the portion affected by the weight of the valve body 150 is stopped in a state where the molten metal surface of the internal space 123 is slightly lower than the molten metal surface in the crucible 112. The supply amount may be any amount of molten metal required for the next die casting.
由圖5的狀態(閥體150浮起的狀態)移至圖2的狀態(閥體150收納於底面部124的狀態),鑄造週期結束。藉由該鑄造週期的重複而使鑄造重複。The state of FIG. 5 (the state in which the valve body 150 floats) is shifted to the state of FIG. 2 (the state in which the valve body 150 is accommodated in the bottom surface portion 124), and the casting cycle is completed. The casting is repeated by repetition of the casting cycle.
以上依照本發明的鋁合金用熱室鑄造機,即使在熔解爐內鋁合金的熔態金屬被填滿構件也無熔損之虞,可得到能以鋁合金當作熔態金屬進行壓鑄的熱室鑄造機。 而且,本發明的鋁合金用熱室鑄造機的鑄造程序能以與習知的熱室鑄造機的活塞式液壓缸方式的週期一樣的速度進行,具有鑄造週期快的優點。 而且,若是習知的活塞式液壓缸方式,則兩者的壁面的加工精度被要求對因使用而造成的畸變或耗損的維修保養被要求等的時候,依照本發明的鋁合金用熱室鑄造機,由於使用氣壓施加液壓缸內的熔態金屬面,因此具有這種加工精度的要求或維修保養的要求少的優點。 而且,在本發明的鋁合金用熱室鑄造機中,由於成為熔態金屬的路徑的射出路徑130位於熔態金屬中,因此無來自外部的空氣的捲入,很少發生氣孔進入壓鑄製品中之不良狀況。 而且,也能抑制如在習知技術的課題說明的於冷室鑄造機看到的裂斷冷硬層的產生。 而且,在本發明的鋁合金用熱室鑄造機中,由於射出壓力較低即可,因此也具有不施加瞬間負載給模具之優點。According to the hot chamber casting machine for aluminum alloy according to the present invention, even if the molten metal of the aluminum alloy in the melting furnace is filled with the member without melting loss, heat which can be die-casted by using the aluminum alloy as a molten metal can be obtained. Chamber casting machine. Further, the casting procedure of the hot chamber casting machine for aluminum alloy of the present invention can be carried out at the same speed as the cycle of the piston type hydraulic cylinder of the conventional hot chamber casting machine, and has an advantage that the casting cycle is fast. Further, in the case of the conventional piston-type hydraulic cylinder system, when the machining accuracy of the wall surfaces of the two is required to be required for maintenance or repair of distortion or wear due to use, the hot chamber casting of the aluminum alloy according to the present invention is required. Since the molten metal surface is applied to the hydraulic cylinder by using air pressure, there is an advantage that such machining accuracy is required or maintenance is less required. Further, in the hot chamber casting machine for aluminum alloy of the present invention, since the injection path 130 which is the path of the molten metal is located in the molten metal, there is no entrapment of air from the outside, and the pores rarely enter the die-cast product. Bad condition. Moreover, it is also possible to suppress the occurrence of a cracked chill layer which is seen in a cold chamber casting machine as explained in the subject of the prior art. Further, in the hot chamber casting machine for aluminum alloy of the present invention, since the injection pressure is low, there is an advantage that the instantaneous load is not applied to the mold.
以上雖然圖示說明了本發明中的較佳的實施例,但不脫離本發明的技術範圍可進行種種的變更應可被理解。While the preferred embodiments of the present invention have been described, it is understood that various modifications may be made without departing from the scope of the invention.
本發明可作為以鋁合金當作熔態金屬使用的熱室鑄造機而廣泛利用。The present invention can be widely used as a hot chamber casting machine using aluminum alloy as a molten metal.
