본 고안은 사출 성형품에 있어서 외측 경사보스 언더컷이 형성된 제품을 사출성형하여 원활히 취출할 수 있게 된 사출금형의 성형품 외측 경사보스 언더컷 처리장치에 관한 것이다.The present invention relates to an injection molding molded article outer inclined boss undercut treatment apparatus that can be ejected smoothly by injection molding the product formed with the outer inclined boss undercut in the injection molded article.
종래에는 제품의 디자인 및 형태의 다양화됨에 따라 일정 경사각도를 갖는 경사면상으로 조립하게 되는 제품의 형태 변화에 따라 제품에 경사보스를 형성시 그에 따른 금형에 있어서, 성형품의 처리장치로써 여러 형태의 경사보스 언더컷 처리장치가 있었으나 구조 복잡하고 작동이 용이하지 못해 불량률 발생이 높게됨과 구조적으로 복잡한 결점이 있었다.Conventionally, when the inclination boss is formed on the product according to the shape change of the product to be assembled on the inclined surface having a predetermined inclination angle according to the diversification of the design and shape of the product, in the mold according to the various forms as a processing apparatus for molded products There was an inclined boss undercut treatment device, but the structure was complicated and not easy to operate, resulting in high defect rate and structurally complex defects.
따라서 본 고안은 이와 같은 종래의 결점을 해소시키기 위해 경사블럭과 스프링을 이용하여 경사면 보스 언더컵 처리를 구조적으로 간단하게 처리할 수 있게된 것으로써 첨부된 도면에 따라 그 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is to be able to easily handle the slope boss undercup treatment using the inclined block and the spring in order to solve such a conventional defect as described in detail the configuration and effect according to the accompanying drawings Is as follows.
고정측 형판(1)과 가동측 형판(2)에 상, 하 코어를 장착하게 되는 사출 금형에 있어서, 고정측 형판(1) 일측에 경사면 a를 갖는 록킹블록(3)을 장착하고, 가동측 형판(2)의 연마판(4) 상면에 T자형 슬라이드 경사홈(5)이 형성된 사이드코어(6)를 장착하면서 가동측 코어(7)의 외측 좌, 우에 걸쳐 장착된 지지편(8)의 조립구(9)를 통해 지지와셔(10)와 스프링(11)을 장착한 볼트(12)를 사이드 코어(6)에 나사 결합하여 스프링(11)의 탄성력이 작용되도록 함과 소정의 경사구(13)가 형성된 가동측코어(7)와 T자형 슬라이드 경사홈(5)사이 경사블록(14)을 끼워맞춤하여 슬라이딩 용이하게 장착한 구성으로써 미설명 부호 15는 제품이고, 16은 밀핀인 것이다.In the injection mold in which the upper and lower cores are attached to the fixed side template 1 and the movable side template 2, a locking block 3 having an inclined surface a is mounted on one side of the fixed side template 1, and the movable side Of the support piece 8 mounted over the outer left and right sides of the movable side core 7 while the side core 6 having the T-shaped slide inclined groove 5 is mounted on the upper surface of the polishing plate 4 of the template 2. A bolt 12 mounted with the support washer 10 and the spring 11 through the assembly opening 9 is screwed to the side core 6 so that the elastic force of the spring 11 is applied and a predetermined inclined sphere ( 13 is formed to fit the inclined block 14 between the movable side core 7 and the T-shaped slide inclined groove 5 so as to slide easily. Reference numeral 15 is a product, and 16 is a milpin.
이와 같이 구성되어진 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.
상부금형과 하부금형을 이동시켜 결합하게 되면 제1(a)도에서 보는 바와 같은 상태가 되며 이 상태에서 소정의 사출품 소재를 금형에 주입하여 제품(15)의 사출성형이 완료된 후 상부 금형인 고정측 형판(1)을 상부로 개방하게 되면 고정측 형판(1)에 장착된 록킹블록(3)도 같이 상향 이동하면서 사이드코어(6)와 록킹블록(3)의 경사면 a가 접지되면서 이동되었던 상태가 가동측코어(7)의 좌, 우에 걸쳐 결착된 지지편(8)의 조립구(9)를 관통하여 사이드 코어(5)에 나사 결합된 볼트(12)에 스프링(11)이 와셔(10)와 지지편(8)사이 장착되어 있는 상태로써 스프링(11)의 복원력이 사이드코어(6)에 작용되는 상태가 항상 유지되는 것으로 사이드코어(6)는 원상태로 복귀 이동하게 되며 이때 사이드 코어(6)의 일측에 T자형 슬라이드 경사홈(5)에는 경사블록(14)이 슬라이딩 용이하도록 결합되면서 가동측 코어(7)의 경사구(13)에 결합되어 있는 상태로써 사이드코어(6)의 이동함에 따라 제2도에서 도시된 바와 같이 결합된 경사블록(14)은 T자형 슬라이드 경사홈(5)을 따라 하향 경사이동하면서 경사블록(14)은 제품(15)으로부터 분리되어 제1b도에서 보는 바와 같은 상태로 분리된 후 통상의 제품(15) 취출동작으로 밀핀(16)이 상향 외동하여 제품(15)을 완전 취출하게 되는 것이다.When the upper mold and the lower mold are combined to move, the state becomes as shown in FIG. 1 (a). In this state, a predetermined injection material is injected into the mold, and the injection molding of the product 15 is completed. When the fixed side template 1 is opened upward, the locking block 3 mounted on the fixed side template 1 also moves upward while the inclined surface a of the side core 6 and the locking block 3 is grounded. The spring 11 is washered to the bolt 12 screwed to the side core 5 through the assembly opening 9 of the support piece 8 whose state is fixed over the left and right sides of the movable side core 7. The state in which the restoring force of the spring 11 acts on the side core 6 is always maintained as the state between the support piece 8 and the support piece 8 is maintained, and the side core 6 moves back to its original state. T-shaped slide inclined groove 5 on one side of the inclined block 14 for sliding The inclined block 14 coupled as shown in FIG. 2 as the side core 6 moves as the state of being coupled to the inclined hole 13 of the movable side core 7 is coupled to the T-shaped slide. The inclined block 14 is separated from the product 15 while being inclined downwardly along the inclined groove 5 and separated in a state as shown in FIG. 1B, and then the pin 10 is removed by the normal product 15 take-out operation. The product 15 is completely taken out by moving upward.
즉, 상부금형의 고정측 형판(1)에 장착된 록킹블록(3)의 경사면 a와 사이드코어(6)와 경사면에 의해 상부금형과 하부금형을 밀착시키게 되면 사이드코어(6)는 스프링(11)의 탄성력을 억제하면서 이동하게 되고 한편 사이드코어(6)의 T자형 슬라이드 경사홈(5)에 장착된 경사블록(14)은 가동측코어(7)의 경사구(13)에 삽입된 상태로 소재를 주입하여 제품(15)의 사출성형 완료한 후 상부 금형을 개방하게 되면 스프링(11)의 복원력에 의해 역동작 순서로 동작되어 원상복귀되는 것으로 계속적인 제품(15)의 사출성형을 완료할 수 있게 되는 것으로 경사보스 언더컷 처리장치의 제반구조가 단순하면서 반영구적으로 신뢰성있는 동작상태를 갖게되므로써 성형품의 품질향상에 기여하게 된 것이다.That is, when the upper mold and the lower mold are brought into close contact with the inclined surface a, the side core 6 and the inclined surface of the locking block 3 mounted on the fixed side template 1 of the upper mold, the side core 6 is spring 11. The inclined block 14 mounted in the T-shaped slide inclined groove 5 of the side core 6 is inserted into the inclined hole 13 of the movable side core 7 while suppressing the elastic force of the side core 6. After the injection molding of the product 15 is completed by injecting the material, when the upper mold is opened, the injection molding of the product 15 may be completed by returning to the original state by operating in the reverse operation order by the restoring force of the spring 11. The overall structure of the inclined boss undercut treatment device has a simple and semi-permanently reliable operation state, thereby contributing to the improvement of the quality of the molded article.
