Description
本發明係有關於一種澆道及其製造方法。The present invention relates to a runner and a method of manufacturing the same.
先前，藉由使被加熱熔融之材料(以下稱做熔融材料)射出到模具內，而成形製品之射出成形係眾所周知。Previously, a material for injection molding of a shaped product was known by ejecting a material to be heated and melted (hereinafter referred to as a molten material) into a mold.
具體說來，使用於射出成形之模具，係具有壓抵到射出熔融材料之射出成形機的射出口部的澆道、及用於形成成形品的形狀部。模具係具有具備作為熔融材料注入空間之澆口的澆道、作為熔融材料填充空間之模穴、及作為熔融材料流路之流道。澆口與模穴係透過流道來連接。Specifically, the mold used for injection molding has a runner that is pressed against the exit port of the injection molding machine that emits the molten material, and a shape portion for forming a molded article. The mold has a runner having a gate as a molten material injection space, a cavity as a molten material filling space, and a flow path as a molten material flow path. The gate and the cavity are connected through the flow path.
在這種射出成形用模具中，在填充到模穴內之熔融材料充分冷卻固化後，自模穴取出成形品。此時，成形品之取出，為了防止材料殘留在澆口及流道內，填充到澆口及流道內之熔融材料係在充分冷卻固化後才實施取出作業。In such an injection molding die, after the molten material filled in the cavity is sufficiently cooled and solidified, the molded article is taken out from the cavity. At this time, in order to prevent the material from remaining in the gate and the flow path, the molten material filled in the gate and the flow path is sufficiently cooled and solidified before being taken out.
一般，每單位面積之容積，係澆口或流道比模穴還要大。但是，填充在澆口或流道內之熔融材料至固化所需時間，比填充在模穴之熔融材料直到固化所需時間還要長。因此，填充在澆口或流道內之熔融材料至固化所需時間若能縮短，就能提高生產效率。Generally, the volume per unit area is larger than the cavity or runner. However, the time required to cure the molten material filled in the gate or runner is longer than the time required to cure the molten material filled in the cavity. Therefore, if the time required for the molten material filled in the gate or the flow path to be cured is shortened, the production efficiency can be improved.
相對於此，提案有藉由在形成流道等之構件處形成冷卻水流路，來縮短填充到流道內等之熔融材料直到固化所需時間的射出成形用模具(例如專利文獻1)。On the other hand, an injection molding die which is formed by forming a cooling water flow path in a member forming a flow path or the like to shorten the time required for the molten material to be filled in the flow path until curing is proposed (for example, Patent Document 1).
在此，當使形成流道之構件或澆道(以下稱做澆道等)以冷卻水來冷卻時，為了提高澆道等之冷卻效率，最好在澆道等之內部形成冷卻水流路。Here, when the member or the runner (hereinafter referred to as a runner) forming the flow path is cooled by the cooling water, it is preferable to form a cooling water flow path inside the runner or the like in order to improve the cooling efficiency of the runner or the like.
另外，為了在冷卻水流路內循環冷卻水，需要用於將供給冷卻水之供水口或排出冷卻水的排出口。又，供水口或排出口，係必須使形成於澆道等內部之冷卻水流路與澆道外部相連接。Further, in order to circulate the cooling water in the cooling water flow path, a discharge port for supplying the cooling water or discharging the cooling water is required. Further, in the water supply port or the discharge port, it is necessary to connect the cooling water flow path formed inside the runner or the like to the outside of the runner.
但是，供水口或排水口係與澆道外部連通，所以，有時自供水口供給來之冷卻水或自排水口供給來之冷卻水會沿著澆道外表面洩漏。如此一來，當沿著澆道外表面洩漏的冷卻水進入流道或模穴內時，成形品會產生品質劣化。However, since the water supply port or the drain port communicates with the outside of the runner, the cooling water supplied from the water supply port or the cooling water supplied from the drain port may leak along the outer surface of the runner. As a result, when the cooling water leaking along the outer surface of the runner enters the flow path or the cavity, the molded article is deteriorated in quality.

澆道10，係具有作為沿著被支撐面10b及被支撐面10c形成之冷卻水流路的筒狀法蘭部水路15(法蘭部水路15a及法蘭部水路15b)。設於被支撐面10b之供水口16a及本體水路14a係以法蘭部水路15a來連接。設於被支撐面10c之供水口16b及本體水路14b係以法蘭部水路15b來連接。The runner 10 has a cylindrical flange portion water passage 15 (a flange portion water passage 15a and a flange portion water passage 15b) as a cooling water flow path formed along the supported surface 10b and the supported surface 10c. The water supply port 16a and the main body water path 14a provided on the supported surface 10b are connected by a flange portion water passage 15a. The water supply port 16b and the main body water path 14b provided on the supported surface 10c are connected by a flange portion water passage 15b.
上模31a，係具有用於供給冷卻水到供水口16a之供水通路33a。上模31b，係具有用於自排水口16b排出冷卻水之排水通路33b。The upper mold 31a has a water supply passage 33a for supplying cooling water to the water supply port 16a. The upper mold 31b has a drain passage 33b for discharging the cooling water from the drain port 16b.
在被支撐面10b與上模31a之間，設有用於防止來自供水口16a的冷卻水洩漏的墊片構件17a(例如O型環等)。墊片構件17a，係包圍供水口16a周圍。另外，在被支撐面10c與上模31b之間，設有用於防止自排水口16b排出的冷卻水洩漏的墊片構件17b(例如O型環等)。墊片構件17b，係包圍排水口16b周圍。A spacer member 17a (for example, an O-ring or the like) for preventing leakage of cooling water from the water supply port 16a is provided between the supported surface 10b and the upper mold 31a. The spacer member 17a surrounds the periphery of the water supply port 16a. Further, between the supported surface 10c and the upper mold 31b, a spacer member 17b (for example, an O-ring or the like) for preventing leakage of the cooling water discharged from the drain port 16b is provided. The spacer member 17b surrounds the periphery of the drain port 16b.
在下模32與上模31a之間及下模32與澆道10之間，形成有流道40。形成於下模32與上模31a之間的模穴50及澆口12係以流道40來連接。A flow path 40 is formed between the lower mold 32 and the upper mold 31a and between the lower mold 32 and the runner 10. The cavity 50 and the gate 12 formed between the lower die 32 and the upper die 31a are connected by a flow path 40.
如此一來，以射出口部20射出之熔融材料，係中介著澆口12及流道40被填充到模穴50，被填充到模穴50內之熔融材料，係在冷卻後被當作成形品取出。In this manner, the molten material ejected from the ejection port portion 20 is filled with the gate 12 and the flow path 40 filled in the cavity 50, and the molten material filled in the cavity 50 is formed into a shape after cooling. Take out the product.
又，當射出口部20壓抵到壓抵面10a時，施加在澆道10上之壓力很大，所以，最好法蘭部分60a、法蘭部分60b、本體部分61a及本體部分61b以具有良好強度之金屬來一體形成。Further, when the ejection port portion 20 is pressed against the pressing surface 10a, the pressure applied to the runner 10 is large, so that it is preferable that the flange portion 60a, the flange portion 60b, the body portion 61a, and the body portion 61b have A good strength metal is formed in one piece.
第1實施形態之澆道10，係無接縫地連接有本體部分61及法蘭部分60。亦即，澆道10，係與本體部分61及法蘭部分60一體形成。又，本體水路14a,14b,14c，係形成於本體部分61內，法蘭部水路15a,15b係形成於法蘭部分60內。因此，流過本體水路14a,14b,14c之冷卻水係直接冷卻被填充到澆口12內之熔融材料，能提高被填充到澆口12內之熔融材料的冷卻效率。In the runner 10 of the first embodiment, the body portion 61 and the flange portion 60 are connected to each other without seams. That is, the runner 10 is integrally formed with the body portion 61 and the flange portion 60. Further, the body water passages 14a, 14b, 14c are formed in the body portion 61, and the flange portion water passages 15a, 15b are formed in the flange portion 60. Therefore, the cooling water flowing through the body water passages 14a, 14b, 14c directly cools the molten material filled in the gate 12, and the cooling efficiency of the molten material filled in the gate 12 can be improved.
又，本體水路14a,14b,14c及連接法蘭部分60外部之法蘭部水路15a,15b，係沿著被支撐面16a,16b形成。而且，當射出成形機之射出口部壓抵到壓抵面10a時，設於法蘭部分60a,60b之被支撐面16a,16b會壓抵在支撐構件，所以，被支撐面16a,16b與支撐構件會密著。因此，流動在本體水路14a,14b,14c及法蘭部水路15a,15b內之冷卻水很難沿著澆道10側面洩漏，而能抑制冷卻水進入流道或模穴內。Further, the main body water passages 14a, 14b, 14c and the flange portion water passages 15a, 15b outside the flange portion 60 are formed along the supported surfaces 16a, 16b. Further, when the injection port portion of the injection molding machine is pressed against the pressing surface 10a, the supported surfaces 16a, 16b provided on the flange portions 60a, 60b are pressed against the supporting member, so that the supported surfaces 16a, 16b and The support members will be tight. Therefore, it is difficult for the cooling water flowing in the body water passages 14a, 14b, 14c and the flange portion water passages 15a, 15b to leak along the side of the runner 10, and it is possible to suppress the cooling water from entering the flow passage or the cavity.
如此一來，能高效地冷卻被填充在澆口內之熔融材料，同時能抑制成形品之品質劣化。In this way, the molten material filled in the gate can be efficiently cooled, and the deterioration of the quality of the molded article can be suppressed.
(澆道之製造方法)接著，參照圖面來說明澆道10之製造方法。第5圖係係表示本發明第1實施形態澆道10之製造方法的流程圖。第14圖係第2圖澆道10之上下顛倒圖面。第9(a)(b)圖、第10(a)(b)圖、第11(a)(b)圖、第12(a)(b)圖及第13(a)(b)圖係表示澆道10之製造工序圖，其分別對應第14圖澆道10之C剖面圖(第15圖)、D剖面圖(第16圖)、E剖面圖(第17圖)、F剖面圖(第18圖)及G剖面圖(第19圖)。而且，在第1實施形態中，澆道10係以金屬製成。茲舉澆道10使用金屬光造形複合加工法來製造之實例來做說明。在此，所謂「金屬光造形複合加工法」，係以YAG雷射或CO2 雷射等熱加工來將金屬粉末材料一層一層燒結堆積，而形成立體形狀，在金屬光造形複合加工法中，在加工途中加上切削加工，而提高尺寸精度或表面粗度。(Manufacturing Method of Sprue) Next, a method of manufacturing the runner 10 will be described with reference to the drawings. Fig. 5 is a flow chart showing a method of manufacturing the runner 10 according to the first embodiment of the present invention. Figure 14 is a top view of the runner 10 in Fig. 2 upside down. Figures 9(a)(b), 10(a)(b), 11(a)(b), 12(a)(b) and 13(a)(b) A manufacturing process diagram of the runner 10 is shown, which corresponds to the C sectional view (Fig. 15), the D sectional view (Fig. 16), the E sectional view (Fig. 17), and the F sectional view of the runner 10 of Fig. 14 ( Figure 18) and G profile (Fig. 19). Further, in the first embodiment, the runner 10 is made of metal. An example in which the sprue 10 is manufactured using a metal photo-forming composite processing method will be described. Here, the "metal light forming composite processing method" is a method in which a metal powder material is sintered and stacked one by one by a hot working such as a YAG laser or a CO 2 laser to form a three-dimensional shape. In the metal light forming composite processing method, Adding machining during machining to increase dimensional accuracy or surface roughness.
(1)首先，準備第6圖所示之金屬光造形複合加工裝置80。金屬光造形複合加工裝置80，係具有可升降地保持工件的工件台81、與工件台81夾持壁體84且可升降地保持金屬粉末90之金屬粉末台82、及配置於金屬粉末90表面之板體83。金屬光造形複合加工裝置80，如第7圖所示，係而且具有照射雷射光之光源86及加工機85。而且，金屬光造形複合加工裝置並不侷限於金屬光造形複合加工裝置80，也可使用種種其他裝置。(1) First, the metal light-shaping composite processing apparatus 80 shown in Fig. 6 is prepared. The metal light-shaping composite processing apparatus 80 has a workpiece stage 81 that can hold the workpiece up and down, a metal powder stage 82 that holds the wall body 84 with the workpiece stage 81, and holds the metal powder 90 up and down, and is disposed on the surface of the metal powder 90. The plate body 83. The metal light shaping composite processing apparatus 80, as shown in Fig. 7, has a light source 86 that irradiates laser light and a processing machine 85. Further, the metal photo-forming composite processing apparatus is not limited to the metal photo-forming composite processing apparatus 80, and various other apparatuses can be used.
(2)接著，如第5圖所示，在步驟S10中，使作為澆道10材料之金屬粉末塗佈成既定厚度。例如如第6圖所示，使工件台81及金屬粉末台82之至少一邊升降而改變相對位置，當金屬粉末90表面之高度比壁體84上端還要高時，作動板體83而使金屬粉末塗佈在工件台81上。(2) Next, as shown in Fig. 5, in step S10, the metal powder as the material of the runner 10 is applied to a predetermined thickness. For example, as shown in Fig. 6, at least one side of the workpiece stage 81 and the metal powder stage 82 is raised and lowered to change the relative position. When the height of the surface of the metal powder 90 is higher than the upper end of the wall 84, the plate body 83 is actuated to make the metal. The powder is coated on the workpiece stage 81.
(3)在步驟S20中，在塗佈有金屬粉末之既定部分處，以第8(a)圖假想線定義之區域，係自光源86照射雷射光而燒結金屬粉末91。在此情形下，在必須空洞之部分(相當於上述澆口12、本體水路14、法蘭部水路15、注入口11、供水口16a及排水口16b之部分)處，使雷射光不照射。亦即，雷射光僅照射相當於法蘭部分60及本體部分61。藉此，如第9(a)(b)圖所示，金屬粉末91係以雷射光照射而與既經燒結之部分成一體。(3) In step S20, in a predetermined portion where the metal powder is applied, the region defined by the imaginary line of Fig. 8(a) is irradiated with laser light from the light source 86 to sinter the metal powder 91. In this case, the laser light is not irradiated at a portion where the cavity is required (corresponding to the gate 12, the body water path 14, the flange portion water path 15, the injection port 11, the water supply port 16a, and the drain port 16b). That is, the laser light is irradiated only to the flange portion 60 and the body portion 61. Thereby, as shown in Fig. 9 (a) and (b), the metal powder 91 is irradiated with laser light and integrated with the sintered portion.
(4)與步驟S10相同地使金屬粉末91塗佈在燒結體10c上，而且以步驟S20依照對應第10(a)(b)圖之區域照射雷射光。在此情形下，在相當於第16圖所示之澆口12及法蘭部水路15(法蘭部水路15a及法蘭部水路15b)的部分處照射雷射光，在相當法蘭部分60及本體部分61的部分照射雷射光。而且，能獲得第10(a)(b)圖所示之燒結體10D。重複步驟S10及S20來形成第11(a)(b)圖、第12(a)(b)圖及第13(a)(b)圖所示之燒結體10E,10F,10G，最終能獲得澆道10。(4) The metal powder 91 is applied onto the sintered body 10c in the same manner as in the step S10, and the laser light is irradiated in accordance with the region corresponding to the 10th (a) and (b) in the step S20. In this case, the portion corresponding to the gate 12 and the flange portion water passage 15 (the flange portion water passage 15a and the flange portion water passage 15b) shown in Fig. 16 is irradiated with the laser light at the corresponding flange portion 60 and A portion of the body portion 61 illuminates the laser light. Further, the sintered body 10D shown in Fig. 10(a)(b) can be obtained. Steps S10 and S20 are repeated to form sintered bodies 10E, 10F, and 10G shown in Figs. 11(a)(b), 12(a)(b), and 13(a)(b), and finally obtain Sprue 10.
在第11(a)(b)圖所示之工序中，對相當於第17圖所示的澆口12、本體水路14(本體水路14a及本體水路14b)及法蘭部水路15(法蘭部水路15a及法蘭部水路15b)之部分不照射雷射光，僅對相當於法蘭部分60及本體部分61之部分照射雷射光。In the step shown in Fig. 11 (a) and (b), the gate 12, the main body water path 14 (the main body water path 14a and the main body water path 14b) and the flange portion water path 15 (flange) shown in Fig. 17 are attached. Portions of the partial water passage 15a and the flange portion water passage 15b) are not irradiated with the laser light, and only the portions corresponding to the flange portion 60 and the body portion 61 are irradiated with the laser light.
在第12(a)(b)圖所示之工序中，對相當於第18圖所示之澆口12及本體水路14之部分不照射雷射光，僅對相當於本體部分61之部分照射雷射光。In the step shown in Fig. 12(a)(b), the portion corresponding to the gate 12 and the body water path 14 shown in Fig. 18 is not irradiated with the laser light, and only the portion corresponding to the body portion 61 is irradiated with the thunder. Shoot light.
在第13(a)(b)圖所示之工序中，對相當於第19圖所示之澆口12及本體水路14(本體水路14c)之部分不照射雷射光，僅對相當於本體部分61之部分照射雷射光。In the step shown in Fig. 13 (a) and (b), the portion corresponding to the gate 12 and the main body water path 14 (the main body water path 14c) shown in Fig. 19 is not irradiated with the laser light, and only the body portion is equivalent. Part of 61 illuminates the laser light.
(5)在步驟S30中，判斷重複步驟S10及步驟S20的次數(重複次數)是否達到既定次數。又，當重複次數達到既定次數時，轉移到步驟S40，當重複次數未達到既定次數時，回到步驟S10之處理。(5) In step S30, it is determined whether or not the number of times (the number of repetitions) of step S10 and step S20 is repeated has reached a predetermined number of times. Moreover, when the number of repetitions reaches a predetermined number of times, the process proceeds to step S40, and when the number of repetitions does not reach the predetermined number of times, the process returns to step S10.
(6)在步驟S40中，針對既經燒結之部分，使第7圖之加工機85作動而實施切削加工等來加工出期望形狀。(6) In step S40, the machining machine 85 of Fig. 7 is actuated by the machining of the portion that has been sintered to perform a cutting process or the like to process a desired shape.
(7)在步驟S50中，判定澆道10是否已經完成。當澆道10已經完成時，結束一連串之處理，當澆道10尚未完成時，回到步驟S10。(7) In step S50, it is determined whether or not the runner 10 has been completed. When the runner 10 has been completed, the series of processes is ended, and when the runner 10 has not been completed, the process returns to step S10.
如此一來，重複金屬粉末之塗佈及燒結，同時每當塗佈及燒結之重複次數達到既定次數時，將既經燒結之部分加以加工而製造澆道10。In this way, the coating and sintering of the metal powder are repeated, and the runner 10 is produced by processing the sintered portion each time the number of repetitions of coating and sintering reaches a predetermined number.
如第15圖~第19圖所示，藉由使用金屬光造形複合加工法，能很容易製造具有複雜形狀之澆道10。As shown in Figs. 15 to 19, the runner 10 having a complicated shape can be easily manufactured by using a metal photoforming composite processing method.
(作用及效果)當使用本發明第1實施形態之澆道10時，澆道10，係使法蘭部分60與本體部分61一體形成。亦即，法蘭部分60與本體部分61係無接縫地相連接。又，本體水路14係形成於本體部分61內，法蘭部水路15係形成於法蘭部分60內。因此，流動在本體部分61之冷卻水的冷卻能力係直接傳遞到被填充在澆口12內之熔融材料，能提高被填充在澆口12內之熔融材料的冷卻效率。(Operation and Effect) When the runner 10 according to the first embodiment of the present invention is used, the runner 10 is formed integrally with the flange portion 60 and the body portion 61. That is, the flange portion 60 is connected to the body portion 61 without seams. Further, the body water passage 14 is formed in the body portion 61, and the flange portion water passage 15 is formed in the flange portion 60. Therefore, the cooling ability of the cooling water flowing in the body portion 61 is directly transmitted to the molten material filled in the gate 12, and the cooling efficiency of the molten material filled in the gate 12 can be improved.
又，連接本體水路14及供水口16a(或排水口16b)的法蘭部水路15，係沿著被支撐面10b(或支撐面10c)來形成。而且，當射出口部20壓抵到壓抵面10a時，設於法蘭部分60之被支撐面10b(或支撐面10c)係壓抵到上模31，所以，被支撐面10b(或支撐面10c)會與上模31密著。因此，流動在本體水路14及法蘭部水路15內之冷卻水不太會沿著澆道10側面洩漏，能抑制冷卻水進入流道40或模穴50內。Further, the flange portion water passage 15 that connects the main body water passage 14 and the water supply port 16a (or the drain port 16b) is formed along the supported surface 10b (or the support surface 10c). Further, when the ejection port portion 20 is pressed against the pressing surface 10a, the supported surface 10b (or the supporting surface 10c) provided in the flange portion 60 is pressed against the upper mold 31, so that the supported surface 10b (or the support) The face 10c) is in close contact with the upper die 31. Therefore, the cooling water flowing in the body water passage 14 and the flange portion water passage 15 does not leak along the side surface of the runner 10, and the cooling water can be prevented from entering the flow passage 40 or the cavity 50.
如此一來，能高效地冷卻被填充在澆口內之熔融材料，同時能抑制成形品的品質劣化。In this way, the molten material filled in the gate can be efficiently cooled, and the deterioration of the quality of the molded article can be suppressed.
又，當使用本發明第1實施形態之澆道10時，包圍澆口12半圓周而具有半圓弧形狀之本體水路14c，係設於排出口13側。亦即，排出口13側之本體水路14的容積，係比注入口11側之本體水路14的容積還要大。Further, when the runner 10 according to the first embodiment of the present invention is used, the main body water passage 14c having a semicircular arc shape surrounding the half circumference of the gate 12 is provided on the discharge port 13 side. That is, the volume of the body water passage 14 on the discharge port 13 side is larger than the volume of the body water passage 14 on the injection port 11 side.
因此，在澆口12容積較大之排出口13側中，流動在本體水路14之冷卻水流量會增加，所以，能提高被填充在澆口12之熔融材料的冷卻效果。Therefore, in the discharge port 13 side where the volume of the gate 12 is large, the flow rate of the cooling water flowing through the body water passage 14 is increased, so that the cooling effect of the molten material filled in the gate 12 can be improved.
主要針對本發明第2實施形態與第1實施形態不同之點來做說明。The second embodiment of the present invention is mainly described as different from the first embodiment.
在第2實施形態之澆道101中，本體水路14d及本體水路14e，係具有沿著末端擴大之澆口12內壁的斜度。In the runner 101 of the second embodiment, the main body water path 14d and the main body water path 14e have a slope of the inner wall of the gate 12 which is enlarged along the end.
如第20圖所示，澆口12，係具有自注入口11往排出口13逐漸擴大之形狀。亦即，如第21圖所示，澆口12內壁12a之延長線L1 ，係相對於與熔融材料射出方向概略平行之直線LP 具有斜度α。又，澆口12內壁12b之延長線L2 ，係相對於與熔融材料射出方向概略平行之直線LP 具有斜度β。而且，斜度α與斜度β可為相同，也可為不同。As shown in Fig. 20, the gate 12 has a shape which gradually expands from the injection port 11 to the discharge port 13. That is, as shown in Fig. 21, the extension line L 1 of the inner wall 12a of the gate 12 has a slope α with respect to a straight line L P which is substantially parallel to the direction in which the molten material is emitted. Further, the extension line L 2 of the inner wall 12b of the gate 12 has a slope β with respect to a straight line L P which is substantially parallel to the direction in which the molten material is emitted. Moreover, the slope α and the slope β may be the same or different.
本體水路14a，係具有沿著澆口12內壁12a之斜度。具體說來，本體水路14a之中心線C1 ，係與內壁12a相同地，相對於與熔融材料射出方向概略平行之直線LP 具有斜度α。亦即，本體水路14a與澆口12內壁12a之距離係保持一定。The body water passage 14a has a slope along the inner wall 12a of the gate 12. Specifically, the center line C 1 of the main body water path 14a has a slope α with respect to the straight line L P which is substantially parallel to the direction in which the molten material is emitted, similarly to the inner wall 12a. That is, the distance between the main body water path 14a and the inner wall 12a of the gate 12 is kept constant.
同樣地，本體水路14b，係具有沿著澆口12內壁12b之斜度。具體說來，本體水路14b之中心線C2 ，係與內壁12b相同地，相對於與熔融材料射出方向概略平行之直線LP 具有斜度β。亦即，本體水路14b與澆口12內壁12b之距離係保持一定。Similarly, the body water passage 14b has a slope along the inner wall 12b of the gate 12. Specifically, the center line C 2 of the main body water path 14b has a slope β with respect to the straight line L P which is substantially parallel to the direction in which the molten material is emitted, similarly to the inner wall 12b. That is, the distance between the body water path 14b and the inner wall 12b of the gate 12 is kept constant.
(作用及效果)當使用本發明第2實施形態之澆道10時，本體水路14a係具有沿著澆口12內壁12a之斜度，所以，本體水路14a與澆口12內壁12a之距離係保持一定，能降低被填充到澆口12內之熔融材料的冷卻不均。同樣地，本體水路14b係具有沿著澆口12內壁12b之斜度，所以，本體水路14b與澆口12內壁12b之距離係保持一定，能降低被填充到澆口12內之熔融材料的冷卻不均。(Operation and Effect) When the runner 10 according to the second embodiment of the present invention is used, the main body water passage 14a has a slope along the inner wall 12a of the gate 12, so the distance between the main body water passage 14a and the inner wall 12a of the gate 12 is It is kept constant to reduce the unevenness of cooling of the molten material filled in the gate 12. Similarly, the body water passage 14b has a slope along the inner wall 12b of the gate 12, so that the distance between the body water passage 14b and the inner wall 12b of the gate 12 is kept constant, and the molten material filled in the gate 12 can be reduced. The cooling is uneven.
以下，主要針對本發明第3實施形態與第1實施形態不同之點來作說明。Hereinafter, the third embodiment of the present invention will be mainly described as being different from the first embodiment.
如第22圖所示，在本發明第3實施形態之澆道102中，本體水路，係具有第1本體水路l4a、第4本體水路14d及第5本體水路14e。第1本體水路14a係與澆口中心軸平行。第1本體水路14a一端，係中介著法蘭部水路連接到供水口，第1本體水路14a另一端，係連接到第4本體水路14d，前述第4本體水路14d，係在澆口熔融材料流動方向上能直行之剖面形狀，以包含前述澆口剖面之圓及同心圓之圓弧的剖面略成C字形區域來定義的前述澆口大徑側中，包圍澆口周圍。第4本體水路14d之另一端，係中介著法蘭部水路15b連接到排水口16b。As shown in Fig. 22, in the runner 102 according to the third embodiment of the present invention, the main body water passage has a first main body water passage 14a, a fourth main body water passage 14d, and a fifth main body water passage 14e. The first body water passage 14a is parallel to the gate center axis. One end of the first main body water passage 14a is connected to the water supply port via a flange portion water passage, and the other end of the first main body water passage 14a is connected to the fourth main body water passage 14d, and the fourth main body water passage 14d flows through the gate molten material. The cross-sectional shape that can be straight in the direction surrounds the gate in the large-diameter side of the gate defined by a circle including a circle of the gate section and a circular arc of a concentric circle, which is defined by a C-shaped area.
