特開２０１０−８９３２７号公報（特許請求の範囲等）JP 2010-89327 A (claims, etc.)

従来の一般的な金型装置や特許文献１記載の金型装置においては、金型内に配置されている管状の加熱装置や冷却装置が直線状に形成されている。直線状に形成されているのは、固化状体の金型内に湾曲または屈曲状の孔を穿孔させ、その孔の中に管状体を配置させるには、非常に手間やコストがかかり、困難であるとともに非効率的であるという理由からである。そのため、成形する樹脂成形品が湾曲状であったり凹凸状に屈曲された形状であったりした場合には、直線状の加熱装置または冷却装置では、金型や樹脂成形品を効率よく加熱または冷却させることができなかった。   In the conventional general mold apparatus and the mold apparatus described in Patent Document 1, the tubular heating apparatus and cooling apparatus arranged in the mold are formed linearly. The straight line is formed by drilling a curved or bent hole in the mold of the solidified body, and placing the tubular body in the hole is very laborious and expensive. This is because it is both inefficient and inefficient. Therefore, when the resin molded product to be molded is curved or bent in an uneven shape, the linear heating device or cooling device can efficiently heat or cool the mold or resin molded product. I couldn't let you.

そこで本発明の目的は、上記問題点を解消し、樹脂成形品を製造する過程において、成形する樹脂成形品が湾曲状または凹凸状に屈曲された形状であっても、効率よく金型を加熱及び冷却させることができる樹脂成形品用金型装置及び当該装置の製造方法を提供することにある。   Accordingly, an object of the present invention is to solve the above problems and efficiently heat the mold even when the resin molded product to be molded is bent or uneven in the process of manufacturing the resin molded product. Another object of the present invention is to provide a mold apparatus for a resin molded product that can be cooled and a method for manufacturing the apparatus.

上記課題を解決するために、本発明の樹脂成形品用金型装置は、金型を加熱する加熱管と、加熱後の金型を冷却する冷却管とを備える樹脂成形品の金型装置において、金型内にて前記加熱管及び前記冷却管が湾曲および／または屈曲していることを特徴とするものである。   In order to solve the above problems, a mold apparatus for a resin molded product of the present invention is a mold apparatus for a resin molded product comprising a heating tube for heating a mold and a cooling tube for cooling the heated mold. The heating tube and the cooling tube are curved and / or bent in the mold.

本発明の樹脂成形品用金型装置においては、前記加熱管及び前記冷却管が、成形する樹脂成形品の形状に沿って金型内に好適に配設されている。   In the mold apparatus for a resin molded product of the present invention, the heating tube and the cooling tube are suitably arranged in the mold along the shape of the resin molded product to be molded.

また、前記加熱管及び冷却管が銅パイプにて形成されていることが好ましい。   Moreover, it is preferable that the said heating pipe and the cooling pipe are formed with the copper pipe.

本発明の樹脂成形品用金型装置の製造方法は、金型を加熱する加熱管と、加熱後の金型を冷却する冷却管とを備える樹脂成形品用金型装置であって、金型内にて前記加熱管及び前記冷却管が湾曲および／または屈曲している樹脂成形品用金型装置の製造方法において、
前記金型内に溝部を形成し、該溝部内に、湾曲および／または屈曲している前記加熱管及び前記冷却管を収容し、加熱管及び冷却管を収容した金型の溝部内に、溶融金属の液状媒体を投入し、ついで該液状媒体を固化させることを特徴とするものである。 A method for producing a mold apparatus for a resin molded product according to the present invention is a mold apparatus for a resin molded product comprising a heating tube for heating a mold and a cooling tube for cooling the heated mold. In the manufacturing method of a mold apparatus for a resin molded product in which the heating pipe and the cooling pipe are bent and / or bent in the inside,
A groove is formed in the mold, the curved and / or bent heating tube and the cooling tube are accommodated in the groove, and melted in the groove of the mold that accommodates the heating tube and the cooling tube. A metal liquid medium is introduced, and then the liquid medium is solidified.

本発明の樹脂成形品用金型装置の製造方法においては、前記液状媒体がアルミニウムであることが好ましい。   In the method for manufacturing a mold apparatus for a resin molded product of the present invention, the liquid medium is preferably aluminum.

本発明によれば、金型内に配置する筒状の加熱管及び冷却管が、成形する樹脂成形品の形状に沿って金型内に配設され得ることから、樹脂成形品を効率よく加熱または冷却させることができる。   According to the present invention, since the cylindrical heating tube and cooling tube disposed in the mold can be disposed in the mold along the shape of the resin molded product to be molded, the resin molded product is efficiently heated.

以下、本発明の樹脂成形品用金型装置における実施の形態を図面に基づいて説明する。
本発明の一実施の形態に係る金型装置１は、雄金型２と雌金型３とを備えている。この金型装置１は、雄金型２及び／または雌金型３を加熱する加熱管１０と、加熱後の金型を冷却する冷却管２０とを具備する。なお、加熱管１０及び冷却管２０は、雄金型２、雌金型３のどちらか一方、もしくは両方に装着しても構わないが、本実施形態においては雌金型３に具備した状態を示す。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a mold apparatus for a resin molded product according to the present invention will be described with reference to the drawings.
A mold apparatus 1 according to an embodiment of the present invention includes a male mold 2 and a female mold 3. The mold apparatus 1 includes a heating pipe 10 for heating the male mold 2 and / or the female mold 3 and a cooling pipe 20 for cooling the heated mold. The heating tube 10 and the cooling tube 20 may be attached to either or both of the male die 2 and the female die 3, but in this embodiment, the state provided in the female die 3 is provided. Show.

加熱管１０及び冷却管２０は筒状に形成されており、両端には、熱水もしくは冷水を吸水または排水する連結装置３０が装着されている。加熱管１０及び冷却管２０は、導電性の高い銅、銀、真鍮、アルミ等の素材が好ましく、特に、導電性や加工面を考慮した場合、銅で形成することが好ましい。   The heating pipe 10 and the cooling pipe 20 are formed in a cylindrical shape, and a connecting device 30 that absorbs or drains hot water or cold water is attached to both ends. The heating tube 10 and the cooling tube 20 are preferably made of materials having high conductivity such as copper, silver, brass, and aluminum. In particular, when considering the conductivity and the processed surface, it is preferable to form the material with copper.

加熱管１０は一端が吸水用連結装置３１に、他端は排水用連結装置３２にそれぞれ連結されている。加熱管１０は、吸水用連結装置３１から送水された熱水を管内に通水させ、熱水の温度により雌金型３を加熱させるものである。また、加熱管１０は、図１に示すように、雌金型装置３内に複数並列した状態で配置される。   One end of the heating tube 10 is connected to the water-absorbing connection device 31 and the other end is connected to the drainage connection device 32. The heating pipe 10 allows hot water sent from the water-absorbing coupling device 31 to pass through the pipe and heats the female mold 3 with the temperature of the hot water. Further, as shown in FIG. 1, a plurality of heating tubes 10 are arranged in parallel in the female mold apparatus 3.

加熱管１０は、一部が湾曲状または屈曲状に形成されている。特に、加熱管１０は、成形する樹脂成形品Ａの形状に沿った状態で雌金型３内に配設される。図２に示すように、成形する樹脂成形品Ａが湾曲状である場合、雌金型３の表面も湾曲状を呈する。そのため、樹脂成形品Ａが配置される雌金型３の内部のキャビティー側表面近傍に加熱管１０を配置させる。これにより、雌金型３を介して樹脂成形品Ａに熱を均一に、且つ効率よく伝えることが可能になる。その結果、高温で溶融した樹脂材料を射出して形成する射出成形において、樹脂成形の際に生じるウエルドラインを未然に防ぐことができる。   A part of the heating tube 10 is formed in a curved shape or a bent shape. In particular, the heating tube 10 is disposed in the female mold 3 along the shape of the resin molded product A to be molded. As shown in FIG. 2, when the resin molded product A to be molded is curved, the surface of the female mold 3 is also curved. Therefore, the heating tube 10 is arranged in the vicinity of the cavity side surface inside the female mold 3 where the resin molded product A is arranged. Thereby, heat can be uniformly and efficiently transmitted to the resin molded product A through the female mold 3. As a result, in the injection molding in which the resin material melted at a high temperature is injected and formed, a weld line generated during the resin molding can be prevented in advance.

冷却管２０は、一端が吸水用連結装置３１に、他端は排水用連結装置３２にそれぞれ連結されている。冷却管２０は、吸水用連結装置３１から送水された冷却装置により冷やされた冷却水を通水し、この冷却水により加熱状態の雌金型３を冷却させることができる。かかる冷却管２０は、加熱管１０の下部に複数配置される。   The cooling pipe 20 has one end connected to the water-absorbing connecting device 31 and the other end connected to the drainage connecting device 32. The cooling pipe 20 allows the cooling water cooled by the cooling device fed from the water-absorbing coupling device 31 to pass through, and the heated female die 3 to be cooled by this cooling water. A plurality of the cooling pipes 20 are arranged below the heating pipe 10.

また、冷却管２０は、一部が湾曲状または屈曲状に形成される。特には、冷却管２０は、樹脂成形品Ａ及び加熱管１０の形状に沿った状態で雌金型３内に配設される。これにより、高温に加熱された雌金型３及び樹脂成形品Ａを効率よく冷却させることができる。   The cooling pipe 20 is partially formed in a curved shape or a bent shape. In particular, the cooling pipe 20 is disposed in the female mold 3 along the shape of the resin molded product A and the heating pipe 10. Thereby, the female metal mold | die 3 and the resin molded product A heated to high temperature can be cooled efficiently.

加熱管１０及び冷却管２０は、図２において緩やかな湾曲状に形成されているが、これに限らず、図８に示すように、箱状の樹脂成形品Ｂを成形する場合、雌金型３の形状に沿った屈曲状に形成することが好ましい。これにより、雌金型３を介して樹脂成形品Ｂに熱や冷気を効率よく伝えることができる。さらに、樹脂成形品Ｂの形状に応じ、加熱管１０及び冷却管２０を螺旋状、湾曲部と屈曲部を組み合わせた形状等、様々な形状に形成してもよい。   The heating tube 10 and the cooling tube 20 are formed in a gently curved shape in FIG. 2, but not limited to this, as shown in FIG. 8, when a box-shaped resin molded product B is formed, a female mold is used. 3 is preferably formed in a bent shape along the shape 3. Thereby, heat and cold can be efficiently transmitted to the resin molded product B through the female mold 3. Furthermore, according to the shape of the resin molded product B, the heating tube 10 and the cooling tube 20 may be formed in various shapes such as a spiral shape, a shape in which a curved portion and a bent portion are combined.

連結装置３０は、加熱管１０に熱水を、冷却管２０に冷水を送り込む吸水用連結装置３１と、熱水及び冷水を金型外へ排水する排水用連結装置３２とからなる。連結装置３０は、図４に示すように、矩形状の枠体部３３と、枠体部３３内に具備された、熱水を吸水する熱水吸水部３４と、熱水吸水部３４から送水された熱水を加熱管１０に送水する第一熱水送水部３５と、加熱管１０へ熱水を送り込む第二熱水送水部３６とを備える。また、連結装置３０は、冷却水を吸水する冷水吸水部３７、第一冷水送水部３８、第二冷水送水部３９を具備する。   The connection device 30 includes a water absorption connection device 31 that sends hot water to the heating tube 10 and cold water to the cooling tube 20, and a drainage connection device 32 that drains the hot water and cold water out of the mold. As shown in FIG. 4, the coupling device 30 includes a rectangular frame 33, a hot water absorbent 34 that absorbs hot water, and water supplied from the hot water absorbent 34. A first hot water supply unit 35 that supplies the heated water to the heating tube 10 and a second hot water supply unit 36 that supplies the hot water to the heating tube 10 are provided. Further, the coupling device 30 includes a cold water absorption unit 37 that absorbs cooling water, a first cold water supply unit 38, and a second cold water supply unit 39.

次に、加熱管１０及び冷却管２０における雌金型３の加熱方法及び冷却方法を図２及び図３に基づき説明する。
まず、雌金型３を加熱させる場合、ヒーター等で加熱された熱水を熱水吸水管４０から雌金型３内に送り込む。送り込まれた熱水は、熱水送水管４１から吸水用連結装置３１内に送水され、送水された熱水は熱水吸水部３４から第一熱水送水部３５を通水し、第二熱水送水部３６から加熱管１０に送り込まれる。加熱管１０内に送り込まれた熱水により雌金型３は加熱され、加熱後、熱水は排水用連結装置３２から雌金型３の外部へ排水される。 Next, a method for heating and cooling the female mold 3 in the heating tube 10 and the cooling tube 20 will be described with reference to FIGS.
First, when the female mold 3 is heated, hot water heated by a heater or the like is fed into the female mold 3 from the hot water absorption pipe 40. The fed hot water is fed into the water absorption coupling device 31 from the hot water feed pipe 41, and the fed hot water is passed through the first hot water feed section 35 from the hot water suction section 34, and the second heat It is fed into the heating tube 10 from the water feeding part 36. The female mold 3 is heated by the hot water fed into the heating tube 10, and after the heating, the hot water is drained from the drainage coupling device 32 to the outside of the female mold 3.

一方、雌金型３を冷却させる場合には、冷却装置（図示せず）にて冷やされた冷水を、冷水吸水管４２から雌金型３内に送り込む。送り込まれた冷水は、冷水送水管４３から吸水用連結装置３１内に送水され、送水された冷水は冷水吸水部３７から第一冷水送水部３８を通水し、第二冷水送水部３９から冷却管２０に送り込まれる。冷却管２０内に送り込まれた冷水により雌金型３は冷却され、冷却後、冷水は排水用連結装置３２から雌金型３の外部へ排水される。   On the other hand, when cooling the female mold 3, cold water cooled by a cooling device (not shown) is fed into the female mold 3 from the cold water suction pipe 42. The fed cold water is fed into the water absorption coupling device 31 from the cold water feed pipe 43, and the fed cold water is passed from the cold water suction section 37 through the first cold water feed section 38 and cooled from the second cold water feed section 39. It is fed into the tube 20. The female mold 3 is cooled by the cold water fed into the cooling pipe 20, and after cooling, the cold water is drained from the drainage coupling device 32 to the outside of the female mold 3.

次に、本発明における金型の製造方法の詳細を、図５乃至図７に基づいて説明する。
図５は、製造方法の第一工程を示すもので、反転させた状態の雌金型３の底面に、加熱管１０及び冷却管２０を収容させる溝部４を形成した状態を示す。また、溝部４の上部には、一端に吸水用連結装置３１と他端に排水用連結装置３２とを装着した、湾曲形状の加熱管１０及び冷却管２０が反転した状態で配置されている。 Next, details of the mold manufacturing method according to the present invention will be described with reference to FIGS.
FIG. 5 shows the first step of the manufacturing method, and shows a state in which the groove portion 4 for accommodating the heating tube 10 and the cooling tube 20 is formed on the bottom surface of the inverted female die 3. In addition, a curved heating tube 10 and a cooling tube 20, each having a water-absorbing coupling device 31 at one end and a drainage coupling device 32 at the other end, are disposed above the groove portion 4.

図６は、製造方法の第二工程を示すもので、雌金型３に形成された溝部４内に、吸水用連結装置３１と排水用連結装置３２を装着した加熱管１０及び冷却管２０を収容させた状態である。加熱管１０及び冷却管２０を溝部４内に収容させた後、溝部４内に、溶融した金属の液状媒体Ｃを投入する。液状媒体Ｃは、特に、熱伝導性と加工性の優れたアルミニウムを用いることが好ましい。この際、アルミニウムを８００℃まで加熱して液状体とし、かかるアルミニウムの液状媒体Ｃを溝部４内に投入する。アルミニウムが液状媒体Ｃであるため、如何なる形状の加熱管１０及び冷却管２０であっても、隙間なく密着させることができる。   FIG. 6 shows the second step of the manufacturing method, in which the heating pipe 10 and the cooling pipe 20 fitted with the water absorption coupling device 31 and the drainage coupling device 32 are placed in the groove 4 formed in the female mold 3. It is in a housed state. After the heating tube 10 and the cooling tube 20 are accommodated in the groove portion 4, the molten metal liquid medium C is put into the groove portion 4. As the liquid medium C, it is particularly preferable to use aluminum having excellent thermal conductivity and workability. At this time, aluminum is heated to 800 ° C. to form a liquid material, and the liquid medium C of the aluminum is put into the groove portion 4. Since aluminum is the liquid medium C, the heating tube 10 and the cooling tube 20 of any shape can be closely attached without any gap.

図７は、製造方法の第三工程を示すもので、溝部４内に投入した液状媒体Ｃが固化した状態を示す。この際、加熱管１０及び冷却管２０は、予め成形する樹脂成形品の形状に沿って形成されているため、如何なる形状の樹脂成形品であっても、その形状に沿って加熱管１０及び冷却管２０を雌金型３内に配設させることができる。   FIG. 7 shows the third step of the manufacturing method, and shows a state in which the liquid medium C introduced into the groove 4 is solidified. At this time, since the heating tube 10 and the cooling tube 20 are formed along the shape of a resin molded product to be molded in advance, the heating tube 10 and the cooling tube 20 are formed along the shape of any shape of the resin molded product. The tube 20 can be disposed in the female mold 3.

上述のように、雌金型３内に溝部４を形成し、かかる溝部４内に筒状の加熱管１０及び冷却管２０を収容させ、加熱管１０及び冷却管２０を収容させた雌金型３の溝部４内に液状媒体Ｃを投入して固化させるため、容易に、且つ効率よく金型及び樹脂成形品を加熱、または冷却させることができる。   As described above, the groove 4 is formed in the female die 3, the cylindrical heating tube 10 and the cooling tube 20 are accommodated in the groove 4, and the female die in which the heating tube 10 and the cooling tube 20 are accommodated. Since the liquid medium C is charged into the three groove portions 4 and solidified, the mold and the resin molded product can be heated or cooled easily and efficiently.
