본 고안은 사출 금형에서 외측 2중 언더컷을 용이하게 처리하기 위한 사출 금형 외측 2중 언더컷 처리 장치에 관한 것이다.The present invention relates to an injection mold outer double undercut processing apparatus for easily processing an outer double undercut in an injection mold.
종래의 경우 사출 금형에서 성형품의 언더컷 처리가 한정되어 있어서 금형의 낙후성 및 성형품의 외관에 많은 영향을 주어 제품의 품질이 떨어졌을 뿐 아니라 기술 축적이 결여되어 제품의 외관에 2중 언더컷 처리가 어려운 문제가 있어서 제품의 품위가 떨어지는 결점이 있었다.In the conventional case, the undercut treatment of the molded article is limited in the injection mold, which affects the moldability and the appearance of the molded article, resulting in poor product quality and lack of technology accumulation, which makes it difficult to process the double undercut. There was a flaw in the quality of the product.
본 고안은 상기와 같은 결점을 해소하기 위하여 안출된 것으로써 금형의 외측 2중 언더컷이 용이하게 처리되므로 성형품의 품질향상 및 기능 향상을 가져오는 효과적인 구조로써 이를 첨부된 도면에 의하여 그 구성 및 작용효과를 상세히 설명하면 다음과 같다.The present invention has been devised to solve the above drawbacks, so that the double undercut of the outside of the mold is easily processed, which is an effective structure that results in improved quality and function of the molded article. When described in detail as follows.
상부고정판(1)에 고정측 형판(2)가 고정측 형판(2)에는 고정측 코어(3)와 앵귤러핀(4)이 결착되고 밀핀(5)을 내장하면서 임의의 형상을 가진 가동측 코어(6)와 앵귤러핀(4) 안내홈이 형성된 슬라이드 코어(7)는 가동측 형판(8)의 상부에 정착되며 슬라이드 코어(7) 내측의 T형 홈을 통해 밀편(9)(9')이 상하 삽입된 상태에서 밀편 지지대(10)가 측방향으로 삽입되고 슬라이드 코어(7)의 상하구멍을 통해 스프링(11)(11')이 삽입된 후 멈춤 나사(12)(12')에 의해 조립되고 밀편지지대(10)의 하부 일정홈에 스프링(11")이 내설된 구성으로써, 미설명 부호(13)는 제품인 것이다.The fixed side template 2 is attached to the upper fixing plate 1, and the fixed side template 2 is fixed to the fixed side core 3 and the angular pin 4, and the movable side core having an arbitrary shape with a built-in mil pin 5. The slide core (7) formed with the guide groove (6) and the angular pin (4) is settled on the upper side of the movable side template (8) and is provided through the T-shaped grooves inside the slide core (7) (9 ', 9'). In this vertically inserted state, the support piece 10 is inserted laterally and the springs 11, 11 'are inserted through the upper and lower holes of the slide core 7, and then, by the stop screws 12 and 12'. Assembled and configured as a spring 11 "in the lower constant groove of the compact support 10, the reference numeral 13 is a product.
이와 같은 구성을 가진 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention having such a configuration in detail as follows.
제1a도에서 보는 바와 같이 가동측 형판(8)에 가동측 코어(6)와 앵귤러핀(4) 안내홈이 형성된 슬라이드 코어(7)가 설치된 상태에서 상부고정판(1)을 하향시키면 앵귤러핀(4)이 안내홈에 끼워지면서 전체적으로 결합된 상태가 되고 임의의 소재를 금형에 주입시켜 제품의 성형이 완료된 상태에서 상부 고정판(1)을 상향으로 이동 개방시키면 고정측 형판(2)에 결착된 앵귤러핀(4)에 의해 앵귤러핀(4) 안내홈이 경사지게 형성된 밀편지지대(10)와 접촉되면서 밀편지지대(10)가 좌측 방향으로 일정거리만큼 작동함에 따라 슬라이드 코어(7)에 내설된 밀편(9)(9')은 밀편지지대(10)와 슬라이딩이 원활해야 하고 밀편(9)(9') 상하에 장착된 스프링(11)(11')의 탄력성을 받고 있기 때문에 밀편지지대(10) 앞쪽 경사면 상에서 원활하게 동시에 하방향과 상방향으로 이동함으로써 제1b도에서 보는 바와 같이 밀편지지대(10)와 밀편(9)(9')이 제품(13)의 언더컷 부분과 분리되며 또한 이 상태에서 계속적으로 상부 고정판(1)을 상향으로 이동함으로써 앵귤러핀(4)은 밀편지지대(10)에 형성된 앵귤러핀(4) 안내홈과 슬라이드코어(7)에 형성된 앵귤러핀(4) 안내홈과 접촉하면서 밀편지지대(10)와 슬라이드코어(7)를 일정거리 만큼 좌측방향으로 이동시킴에 따라 슬라이드코어(7)에 내설된 내부 장치는 전체적으로 경사진 안내홈의 기울기에 따른 이동거리만큼 이동하여 제품(13)과 내부사출 장치들과 이탈시킨 상태에서 밀핀(5)을 동작시켜 완성된 제품(13)을 취출하게 된다.As shown in FIG. 1A, when the upper fixing plate 1 is lowered in the state in which the slide core 7 having the movable side core 6 and the angular pin 4 guide grooves are formed on the movable side template 8, the angular pin ( 4) is inserted into the guide groove as a whole combined state and injecting any material into the mold to move the upper fixing plate 1 upward in the state where the molding of the product is completed, the angular is bound to the fixed side template (2) When the angular pin (4) guide groove is inclined by the pin (4) in contact with the compact support (10) is formed inclined to the slide core (7) as the compact support (10) operates a certain distance in the left direction (9) (9 ') has a smooth support for sliding with the compact support (10) and the elastic support of the spring (11) (11') mounted above and below the compact support (9) (9 ') 10) by moving downward and upward smoothly on the front slope As shown in FIG. 1B, the pin support 10 and the pins 9 and 9 'are separated from the undercut portion of the product 13, and in this state, the angular pin is continuously moved upward by moving the upper fixing plate 1 upward. (4) is in contact with the angular pin (4) guide groove formed in the chuck support (10) and the angular pin (4) guide groove formed in the slide core (7) the chuck support (10) and the slide core (7) As the internal device installed in the slide core 7 moves toward the left by a predetermined distance, the pin moves while being separated from the product 13 and the internal injection devices by moving by the moving distance according to the inclination of the inclined guide groove as a whole. By operating (5), the finished product 13 is taken out.
즉, 고정측 형판(2)에 결착된 앵귤러핀(4)이 밀편지지대(10)에 형성된 안내홈의 기울기에 따라 1차 이동되고 이때 슬라이드코어(7)에 내설된 밀편(9)(9')은 스프링(11)(11')의 탄력성에 의해 상하로 작동되며 2차 이동은 안내홈의 기울기에 의해 슬라이드코어(7) 전체가 제1c도에서 보는 바와 같이 제품(13)에서 완전히 이탈하게 되는 것이며 또한 금형이 닫힐 때는 열릴 때의 동작순서와 역행으로 동작되는 것으로써 사출 금형의 외측 2중 언더컷 처리 작동을 용미하게 할 수 있을 뿐 아니라 다수개의 언더컷 처리도 동시에 할 수 있으며 금형의 구조적 결함을 해소하여 금형의 동작이 안전하므로 모든 제품의 외관에 따른 품질을 향상시키고 생산능률을 높일 수 있게 된 것이다.That is, the angular pins 4 attached to the fixed side template 2 are primarily moved according to the inclination of the guide grooves formed in the pin support 10, and the pins 9 and 9 embedded in the slide core 7 at this time. ') Is operated up and down by the elasticity of the springs 11 and 11' and the secondary movement is completely disengaged from the product 13 by the inclination of the guide groove as shown in FIG. In addition, when the mold is closed, the operation sequence and the reverse operation when it is opened can not only make the double undercut processing of the outer mold of the injection mold easier but also simultaneously perform a plurality of undercut treatments. By eliminating the problem of the safe operation of the mold, it is possible to improve the quality according to the appearance of all products and increase the production efficiency.
