Description

전기자동차 또는 전기이륜차의 바테리 팩 케이스 제조를 위한 사출 성형 금형{INJECTION MOLDING MOLD FOR MANUFACTURING BATTERY PACK CASE OF ELECTRIC VEHICLE OR ELECTRIC MOTORCYCLE}INJECTION MOLDING MOLD FOR MANUFACTURING BATTERY PACK CASE OF ELECTRIC VEHICLE OR ELECTRIC MOTORCYCLE}

본 발명은 전술한 문제를 해결하기 위하여 안출된 것으로, 본 발명은 사출성형용 금형에 관한 것으로써, 특히, 제1분할코어와, 상기 제1분할코어에 인접하게 배치되는 제2분할코어와, 상기 제1분할코어와 상기 제2분할코어를 결합시키는 결합부재를 포함하며, 상기 제1분할코어 및 상기 제2분할코어와 결합부재 중 하나에는 결합돌기가 형성되고, 나머지 하나에는 상기 결합돌기가 삽입되는 걸림홈이 형성되는 것을 특징으로 하는 사출성형용 금형을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, the present invention relates to an injection molding die, in particular, a first split core, a second split core disposed adjacent to the first split core, And a coupling member coupling the first split core and the second split core, wherein one of the first split core and the second split core and the coupling member is provided with a coupling protrusion, and the other is the coupling protrusion. It is an object of the present invention to provide a mold for injection molding, characterized in that the engaging groove is inserted.

종래의 사출성형용 금형은 사이드게이트금형에서 고정측형판(1)에는 가이드핀(2)을 설치하여 인서트너트(20)를 임시고정할 수 있도록 하고, 가동측형판(3)에는 다수개의 너트고정편(4)을 설치하여 금형이 닫힐때 너트고정핀(4)의 단부가 인서트 너트(20)를 압압하여 인서트 너트(20)가 이동하지 못하도록 고정하여서 된것으로서 도면중 미설명 부호 11은 받침판, 10은 몰드물, 12는 스프로우, 13은 게이트, 15는 이젝트핀이다.Conventional injection molding dies are provided in the side gate mold to be fixed to the fixed side plate (1) by the guide pin (2) to temporarily fix the insert nut 20, the movable side plate (3) a plurality of fixed nuts When the piece 4 is installed and the mold is closed, the end of the nut fixing pin 4 presses the insert nut 20 to fix the insert nut 20 so that the insert nut 20 does not move. 10 is a mold, 12 is a sparrow, 13 is a gate, and 15 is an eject pin.

이와같이 구성된 본 고안의 작용효과는 수지를 사용하여 인서트너트를 구비하는 몰드물(10)을 성형하고자 할때 고정측형판(1)에 설치된 가이드핀(2)에 인서트 너트 (20)를 끼워 가고정한 후 가동측형판(3)을 닫으면 가동측형판(3)의 전면보다 약간 돌축되게 설치되어 있으며 후면은 받침판(11)에 지지된 다수개의 너트 고정핀(4)이 인서트 너트(20)는 가이드핀(2)에 견고하게 고정되며 이와같은 상태에서 수지를 흘려주게되면 수지는 스프로우(12)를 지나 게이트(13)을 통해 내부로 흘러들어 형합물을 형성하게 되는데, 이때 수지의 흐름방향이 인서트 너트(20)를 고정측형판(1) 방향으로 밀어주는 방향으로 압력을 가하면서 충전하게되어 인서트 너트(20)를 고정측형판(1) 방향으로 압력을 가하면서 충전하게되어 인서트너트(20)는 제 위치에 고정된 상태에서 형합물을 형성하게 된다.The effect of the present invention configured as described above is to temporarily insert the insert nut 20 into the guide pin 2 installed on the fixed side plate 1 when molding the mold 10 having the insert nut using resin. After closing the movable side plate (3) is installed slightly stiffer than the front side of the movable side plate (3), the rear is a plurality of nut fixing pins (4) supported by the support plate (11) insert nut 20 is a guide pin When the resin is firmly fixed to (2) and the resin is flowed in such a state, the resin flows through the gate 12 through the gate 12 to form a compound, and the resin flow direction is insert. The nut 20 is charged while applying pressure in the direction of pushing the fixed side plate 1, and the insert nut 20 is charged while applying pressure in the direction of the fixed side plate 1 to the insert nut 20. The compound is fixed in place Will form.

이와같이 형합물을 충진한 상탱서 온도를 낮추어 고형시킨후 가동측형판(3)을 후진시키면 형합물(10)은 인서트 고정핀(2)에 끼인상태에서 고정측형판(1)에서 벗어나게되며 이후 가동측형판이 후진을 계속함에 따라 이젝트핀(15)이 형합물을 외주면을 밀어주게 되므로 형합물은 인서트 너트 고정핀(2)에서 빠지게 된다.Thus, after lowering the temperature of the upper tanker filled with the mold to solidify, the movable side plate 3 is retracted, and the mold 10 is released from the fixed side plate 1 while being caught by the insert fixing pin 2, and then operated. As the side plate continues reversing, the eject pin 15 pushes the outer surface of the mold, so that the mold is removed from the insert nut fixing pin 2.

이와같은 과정에 의해 제조하고자 하는 형합물의 정위치에 인서트 너트를 형합시킬수 있게 된다.By this process it is possible to mold the insert nut in place of the molding to be produced.

그러나, 이러한 종래의 금형은 한 금형당 한 사이즈의 성형품만 제조할 수 있어서 다양한 크기의 성형품을 제조할 수 없는 문제점이 있다. 또한, 금형의 일부분이 손상되었을 경우에도 금형 전체를 교체해야 하여 유지보수비용이 커지는 문제점이 있다.However, such a conventional mold has a problem in that only one sized molded article can be manufactured per one mold, and thus a molded article of various sizes cannot be manufactured.

In addition, each of the second dividing cores 202 is provided with engaging grooves 203a on both outer circumferential surfaces thereof so that another second dividing core 202 or another first dividing core 201 can be connected.

나아가, 결합부재(204)에는 하부에 나사산이 형성된 체결공(205)이 형성되어 있다.Further, the coupling member 204 is formed with a fastening hole 205 formed with a screw thread at the bottom.

제1분할코어(201)와 제2분할코어(202)의 외주면에는 걸림홈(203a, 201b)에 연통되도록 체결공(205)에 체결되는 볼트(207)가 안착되는 볼트안착구멍(206)이 상하방향으로 형성된다. 볼트안착구멍(206)에는 볼트(207) 머리가 걸리는 걸림턱이 형성된다.On the outer circumferential surface of the first split core 201 and the second split core 202, a bolt seating hole 206 on which a bolt 207 fastened to the fastening hole 205 is mounted to communicate with the engaging grooves 203a and 201b. It is formed in the vertical direction. The bolt seating hole 206 has a latching jaw to which the head of the bolt 207 is caught.

이러한 상부코어(200)는 성형품(100)의 사이즈에 따라 걸림홈(203a, 201b)에결합부재(204)의 결합돌기(204a,b)를 삽입하여 제1분할코어(201)와 제2분할코어(202)를 연결하여 사용할 수 있다.The upper core 200 is inserted into the engaging projections (204a, b) of the coupling member 204 in the engaging grooves (203a, 201b) according to the size of the molded article 100 and the first divided core 201 and the second division. The core 202 can be connected and used.

이로 인해, 금형의 길이를 다양하게 조절할 수 있어서 다양한 길이의 성형품(100)을 성형할 수 있고, 코어의 부분 손상시 손상된 부분만 교체할 수 있어서 유지보수 비용이 절감되고, 교체도 용이하여 유지보수도 용이해진다.Due to this, the length of the mold can be adjusted in various ways to form molded articles 100 of various lengths, and only damaged parts can be replaced when parts of the core are damaged, thereby reducing maintenance costs and easily replacing them. It also becomes easy.

또한, 걸림홈(203a, 201b) 및 결합돌기(204a,b)이 상기와 같이 형성되어, 단순한 구조로 분할된 코어를 견고하게 결합할 수 있어서 조립이 용이해지고 금형제조도 용이해진다.In addition, the engaging grooves 203a and 201b and the engaging projections 204a and b are formed as described above, so that the cores can be firmly coupled in a simple structure, thereby facilitating assembly and making molds.

나아가, 상부코어(200) 조립 후에 결합부재(204)의 체결공(205)에 볼트안착구멍(206)에 안착된 볼트(207)를 체결하여 결합부재(204)가 이탈되지 않고 고정되게 된다.Furthermore, after assembling the upper core 200, the bolt 207 seated in the bolt seating hole 206 is fastened to the fastening hole 205 of the coupling member 204 so that the coupling member 204 is fixed without being separated.

도 7은 본 실시예의 분할된 코어를 조립한 상태에서 저면을 보았을 때 도면이다.Fig. 7 is a view of the bottom face of the divided core of this embodiment in an assembled state.

도 7에 도시된 바와 같이, 본 발명의 상부코어(200)는 상기와 같이 형성되어, 성형품(100) 재료가 맞닿는 면이 분할된 코어 조립한 후에도 매끈하게 되어 양품의 제품을 생산할 수 있다.As shown in FIG. 7, the upper core 200 of the present invention is formed as described above, so that even after assembling the core in which the surface where the molded article 100 is in contact with the material is divided, it is possible to produce a good product.

상술한 바와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당기술분야의 당업자는 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 또는 변형하여 실시할 수 있다.It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
