Install the mill plate 6 and pin support plate 7 to mount the mill pin 8 on the upper end surface thereof, and mount the locking block 12 'and the lower core 11 to the lower disc 3 with bolts and (2) bolts the upper core (9), the guide bush (19) and the three-stage rod bush (18) on one side of the inner and the safety ring device (20) on one side of the upper disc (2) and the lower disc (3) (20 ') and the three-stage rod (16) having the washer (22) assembled on one side of the upper fixing plate (1) is mounted through the upper disk (2) and the lower disk (3) and the lower disk (3) On one side, a guide pin 17 is mounted through the upper disc 2, and a slide core 10 in which the angular pin 13 is installed on the inclined surface of the locking block 12 'is mounted and slides. Ball franja 21 is installed below the upper disc 2 so that the child 10 can operate a certain stroke. Reference numeral 14 denotes the sprue bush 15 for the rocket ring, and 23 for the molded product. to be.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
상기와 같이 조립된 본원은 제1a도에서 보는 바와 같이 슬라이드 코아(10)를 지지하는 2중 로킹 블록(12)(12')을 설치하여 스푸루 부시(14)를 통하여 사출물을 유입할 때 사출압에 의하여 슬라이드 코아(10)가 밀리는 것을 방지하였으며 사출 작업이 완료되어 1차적 작동으로 상부 고정판(1)이 열리면서 도면 제1b도와 같이 상부 고정판(1)에 장착된 로킹블록(12)과 앵귤러핀(13)이 상승하며 앵귤러핀(13)의 경사각도에 따라 슬라이드 코아(10)가 이동할 때 하부원판(3)에 장착된 로킹블록(12')과 상부원판(2)에 설치된 볼프란자(21)에 의해 일정 스트로크 이동하여 언더컷을 처리하고 정지된다.As assembled in the present application, as shown in FIG. 1a, a double locking block 12, 12 ′ supporting the slide core 10 is installed to inject the injection material through the sprue bush 14. The slide core 10 is prevented from being pushed by the pressure, and the injection block is completed, and the upper fixing plate 1 is opened by the first operation, and the locking block 12 and the angular pin mounted to the upper fixing plate 1 as shown in FIG. When the slide core 10 moves according to the inclination angle of the angular pin 13, the locking block 12 ′ mounted on the lower disc 3 and the ball franja 21 mounted on the upper disc 2 are raised. The stroke is moved by a certain stroke, and the undercut is processed and stopped.
또한, 1차 작동시 상부원판(2)과 하부원판(3)에 설치된 안전고리 장치(20)(20')에 의해 2차 작동부분의 유동을 억제하여 준다.In addition, by the safety ring device 20, 20 'installed in the upper disk (2) and the lower disk (3) during the primary operation to suppress the flow of the secondary operating portion.
이후 계속되는 2차 작동에서 제1c도에서 보는 바와 같이 상부고정판(1)에 장착된 삼단봉(16)이 작동하여 삼단봉(16)의 하측에 조립된 와셔(22)가 상부원판(2)의 하측을 지지하여 안전고리 장치(20)(20')를 해체하고 상부원판(2)과 하부원판(3)을 분리시켜 사출품(23)을 취출할 수 있는 거리를 조정하여 주어 에젝트 봉(도시되지 않았음)이 밀판(6)과 핀지지판(7)을 상승시켜 밀핀(8)에 의하여 사출품(23)을 하측 코아(11)에서 분리시켜 취출하게 된 사출금형의 앵귤러핀에 의한 대형 언더컷 처리장치이다.In the subsequent secondary operation, as shown in FIG. 1C, the three-stage rod 16 mounted to the upper fixing plate 1 is operated so that the washer 22 assembled to the lower side of the three-stage rod 16 opens the lower side of the upper disc 2. By disassembling the safety loop device 20, 20 'and separating the upper disc 2 and the lower disc 3 to adjust the distance at which the injection molded product 23 can be taken out. Large undercut treatment by the angular pin of the injection mold which raises the mill plate 6 and the pin support plate 7 and separates the injection molded product 23 from the lower core 11 by means of the mill pin 8. Device.
상기에서 상술한 바와 같이 표준 금형 장치에 삼단 금형장치의 원리를 첨가하고 안전고리 장치를 설치하여 앵귤러핀에 의해 슬라이드 코아를 작동시켜 대형 언더컷을 처리하기 때문에 금형 장치의 대형화를 방지하고 코아선이 제품의 외관에 생기는 것을 해결하여 제품의 외관에 따른 품질 향상과 생산능률을 높일 수 있게된 것이다.As described above, the principle of the three-stage mold apparatus is added to the standard mold apparatus, and the safety hook device is installed to operate the slide core by the angular pin to handle the large undercut, thereby preventing the mold apparatus from becoming large and the core line product. By solving the appearance of the product can improve the quality and production efficiency according to the appearance of the product.
