본 고안은 대형성형제품(세탁기의 톱커버 등)을 성형하는 사출금형 장치에 있어서, 사출가공후 금형장치로 부터 제품을 취출하는데 지지블럭과 성형코어 및 슬라이드코어를 이용함으로서 제품을 안전하게 취출할 수 있도록 한 사출금형의 대형성형제품 취출장치에 관한 것이다.The present invention is an injection mold apparatus for molding a large molded product (such as a top cover of a washing machine), and the product can be safely taken out by using a support block, a molding core and a slide core to take out the product from the mold apparatus after injection processing. The present invention relates to an apparatus for ejecting large molded products of an injection mold.

종래의 경우, 사출금형장치에서 세탁기의 톱커버등 성형높이가 높고 직각인 부위를 갖는 대형제품 성형완료후, 제품취출시에는 성형품이 금형장치의 상측에 달라붙어 성형품이 흩어지는 등, 취출이 원활하지 않으므로서, 제품의 품질저하는 물론, 양산성이 저하되는 등 여러결점이 있었다.In the conventional case, after completion of molding a large product having a high vertical angle and a high molding height such as a top cover of a washing machine in an injection molding machine, when the product is taken out, the molded article sticks to the upper side of the mold apparatus and the molded article is scattered smoothly. As a result, there are various disadvantages such as deterioration of the product quality and deterioration of mass productivity.

따라서 본 고안은 상기와같은 종래의 결점을 해소시키기 위해서, 사출금형장치에 있어서, 성형높이가 높고, 직각인 대형성형품 사출가공후 제품을 취출하는데 지지블럭, 성형코어 및 슬라이드코어를 이용함으로서 제품을 안전하게 취출할 수 있도록 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention provides a product by using a support block, a molding core, and a slide core in the injection mold apparatus, in order to remove the product after injection molding of a high molding angle and a large molded product in order to solve the above-mentioned drawbacks. When described in detail the configuration and effect by the accompanying drawings to be drawn out to be safely taken out as follows.

상고정판(1)에 상형판(2)이 고정된 상부금형(H)과 하고정판(도시되지 않음)에 지지블럭(3)을 통해 하코어(4)가 장착된 하형판(5)이 결착조립된 하부금형( L)으로서 그 하부금형(L)에는 밀핀(6)이 하형판(5), 하코어(4)를 관통한 일반적인 사출금형장치에 있어서, 상기 상고정판(1)에 걸린 걸림턱(7a)과 T자형돌부(7b)가 일체로 된 지지블럭(7)을 볼트 체결시키되, T자형돌부(7a)에는 T자형홈(8a)을 매개로 가이드홈(8b) 경사면(8c)이 형성된 성형코어(8)를 유동가능케 결합하여 상형판(2)에 내장시킴과, 하형판(5) 일측에는 경사면 (9a)를 갖는 슬라이드코어(9)를 수평 유동가능케 결합하여 경사면(9a)과 성형코어(8)의 경사면(8c)이 접하도록 구성된 것으로 미 설명부호 10은 스프루부시, 11은 노즐, 12는 제품, 13은 고리, 14는 인장봉, 15는 부시, 16은 가이드핀, 17은 앵글러핀인 것이다.The upper mold H, to which the upper plate 2 is fixed to the upper fixing plate 1, and the lower plate 5 to which the lower core 4 is mounted through the support block 3, are fixed to the fixing plate (not shown). Assembled lower mold (L), the lower mold (L) has a pin pin (6) in the general injection mold apparatus penetrating the lower mold plate 5, the lower core (4), is caught by the upper fixing plate (1) Tighten the support block 7 in which the jaw 7a and the T-shaped protrusion 7b are integrally bolted to each other. The formed forming cores 8 are coupled to each other so as to be flowable and embedded in the upper plate 2, and the slide cores 9 having the inclined surface 9a on one side of the lower plate 5 are horizontally coupled to the inclined surface 9a. And reference numeral 10 denotes a sprue bush, 11 a nozzle, 12 a product, 13 a ring, 14 a tension rod, 15 a bush, and 16 a guide pin. , 17 is angler pin All.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같ㄷ가.When explaining the effect of the present invention configured as described as follows.

상고정판(1)과 상형판(2)으로 된 상부금형(H)의 스프루부시(10)에 노즐(11)을 끼워맞춤후 소저의 소재를 주입하여 사출성형이 완료된 후 제품(12)을 금형장치로 부터 분리하기 위해서 상부금형(H)을 개방시켜주면, 상, 하형판 (2) (5)이 고리 (13)에 의해 벌어지지 않는 상태에서 상고정판(1)이 상승되므로 이에 고정된 지지블럭(7) 및 인장봉(14)이 상승되는데, 이때, 지지블럭(7)의 걸림턱(7a)이 성형코어(8)의 가이드홈(8b)내에 위치되어 있으므로, 지지블럭(7) 상승과정에서 일정스트로크(S1)만큼 상승되면 걸림턱(7a)이 가이드홈(8b) 상부에 걸리게 됨에 따라 성형코어(8)는 상승이 되는 지지블럭(7)에 의해 슬라이드코어(9)의 경사면(9a)을 따라 일정거리만큼 상승되므로 제품(12)의 직각부위(a)에서 떨어지며, 이와 동시에 인장봉(14)은 일정스트로크(S2)만큼 이동되어 부시(15)하단에 밀착 걸리게 되어 1차 파팅라인이 분리완료된다. (도면 제 2 도에 도시됨)Fit the nozzle 11 to the sprue bush 10 of the upper mold (H) consisting of the upper fixing plate (1) and the upper plate (2), and then inject the material of the soot to complete the injection molding (12). When the upper mold (H) is opened to separate from the mold apparatus, the upper and lower mold plates (2) and (5) are lifted by the upper fixing plate (1) in a state where they are not opened by the ring (13). The support block 7 and the tension bar 14 are raised at this time, since the locking jaw 7a of the support block 7 is located in the guide groove 8b of the forming core 8, so that the support block 7 In the ascending process, when a certain stroke S 1 is raised, the locking jaw 7a is caught by the upper portion of the guide groove 8b, so that the forming core 8 is moved by the support block 7 which is raised. Since it rises by a predetermined distance along the inclined surface (9a), it falls from the perpendicular portion (a) of the product 12, at the same time the tension rod 14 is moved by a constant stroke (S 2 ) Close to the bottom of the pore 15, the primary parting line is separated. (Shown in figure 2)

상기와 같은 상태에서 상부금형의 계속적인 상승동작으로 인장봉(14)이 상형판(2)을 상향이동시키므로 고리(13)가 해체되어 상형판(2)과 하형판 (5) 사이가 벌어지면서 상형판(2)이 가이드핀(16)에 안내되면서 상향이동 되어진다.In the above state, the tension rod 14 moves the upper plate 2 upward by the continuous upward motion of the upper mold, so that the ring 13 is dismantled so that the space between the upper plate 2 and the lower plate 5 opens. The upper plate (2) is moved upward while being guided to the guide pin (16).

따라서 상형판(2)에 고정된 앵귤러핀(17)이 동시 상향이 되므로 하형판(5)에 일측에 결합된 슬라이드 코어(9)가 도면상 좌측으로 슬라이드 이동되어 도면 제 3 도에 도시된 바와 같이 제품 (12)의 (b)부위에서 떨어진다.Therefore, since the angular pin 17 fixed to the upper plate 2 is simultaneously upward, the slide core 9 coupled to one side of the lower plate 5 is slid to the left in the drawing, as shown in FIG. 3. As well as in part (b) of product (12).

즉, 제품 (12)의 (a) 및 (b)부위에서 성형코어(8) 및 슬라이드코어(9)가 떨어진 상태가 된다.In other words, the forming core 8 and the slide core 9 are separated from each other in the portions (a) and (b) of the product 12.

이와같은 상태에서 밀핀 작동수단에 의해 하형판(5) 및 하코어(4)를 관통한 밀핀(6)를 상향동작시켜주면 제품(12)은 밀핀(6)에 의해 상향으로 취출되어진다.In this state, when the mil pin 6 penetrates the lower mold plate 5 and the lower core 4 by the mil pin actuating means, the product 12 is taken out upward by the mil pin 6.

이상에서 본 바와 같이 본 고안은 3단 특수구조 형식으로 사출금형 장치를 개발하여 성형높이고 높고 직각인 대형성형품(세탁기의 톱커더 등) 사출가공후 제품을 취출하는데, 지지블럭(7), 성셩코(8) 및 슬라이드 코어(9)를 이용함으로서 취출시 제품이 금형에 달라붙지 않음으로 대형제품을 안전하고 원활하게 취출할 수 있어 제품생산을 능률적으로 사용성형할 수 있게 된 것이다.As described above, the present invention develops an injection mold apparatus in a three-stage special structure type and takes out the product after injection processing of high-molded, high-molded large-sized products (such as a top cutter of a washing machine). By using the (8) and the slide core (9), the product does not stick to the mold at the time of taking out, so that large products can be taken out safely and smoothly, so that the product production can be efficiently used and molded.
