도면중의 부호 27은 워크(work) 및 성형된 컵 형상의 제품을 도시한 것이다.Reference numeral 27 in the drawings shows a workpiece and a molded cup shaped product.

상기와 같이 구성되는 본 발명의 진공흡입 디프-드로잉 성형용 금형(1)은 주로 컵 형상의 제품을 프레스기에서 디프-드로잉 성형 시에 사용되는 것으로서,The vacuum suction deep-drawing molding die 1 of the present invention constituted as described above is mainly used for deep-drawing molding of a cup-shaped product in a press machine,

본 발명은 컵 형상 제품을 만들고자 하는 소재, 즉 워크(27)를 하금형(5)의 다이블록(22)에 고정된 다이(21)상에 안치하고, 프레스기를 가동시켜 상금형(3)을 도 2의 상태에서 도 3과 같이 하강작동시키면 상금형(3)이 하금형(5)상으로 가이드핀(6)에 안내 하강하면서 상금형(3)의 하측 기밀스트리퍼(13)가 하금형(5)의 다이블록(22)에 연접되면서 씰패킹(20)에 의해 기밀이 유지되고, 상기 기밀스트리퍼(13)는 질소가스스프링(14)과 패드(15)를 통해 쿠션핀(16)에 지지되어 있어 적정 텐션으로 다이블록(22)에 기밀력을 유지하면서 밀착 연접되는 것이다.According to the present invention, a work material 27, ie, a work 27, is to be placed on a die 21 fixed to a die block 22 of a lower mold 5, and a press machine is operated to move the upper mold 3 to a cup-shaped product. In the state of FIG. 2, when the lowering operation is performed as shown in FIG. 3, the lower airtight stripper 13 of the upper mold 3 is lowered while the upper mold 3 guides and lowers onto the guide pin 6 onto the lower mold 5. The airtightness is maintained by the seal packing 20 while being connected to the die block 22 of 5), and the airtight stripper 13 is supported by the cushion pin 16 through the nitrogen gas spring 14 and the pad 15. As a result, the die block 22 is closely connected while maintaining the airtight force with the appropriate tension.

그리고 기밀스트리퍼(13)가 다이블록(22)에 연접됨과 동시에 가이드펀치(12)가 하강하면서 워크(27)를 다이(21)의 성형부로 가압성형하게 되는데, 이때 가이드펀치(12)는 단 1회의 하강작동에 의하여 워크(27)를 컵 형상으로 성형하게 되는 바, 이는 워크(27)가 컵 형상으로 성형되는 다이(21)의 내부 성형부가 고진공 흡입상태를 유지하기 때문에 가능한 것이다.As the airtight stripper 13 is connected to the die block 22 and the guide punch 12 is lowered, the work 27 is press-molded to the forming portion of the die 21, wherein the guide punch 12 is only 1. The work 27 is formed into a cup by the lowering operation of the bar, which is possible because the internal forming portion of the die 21 in which the work 27 is formed into a cup shape maintains a high vacuum suction state.

즉, 상금형(3)의 하강작동 시 푸시펀치(11)도 동시에 하강하면서 하금형(5)상에 이젝터스프링(24a)으로 상향 탄력지지된 진공피스톤(23)을 강제로 하강시켜 워크(27) 성형부를 폐쇄하고 있던 이젝터핀(24)이 진공피스톤(23)과 동시에 결합공(25)에 안내되면서 하강하게 되어 다이(21)의 성형부 내부는 진공흡인력을 발생시키게 되는 것이다.That is, when the lowering operation of the upper die 3, the push punch 11 is also lowered at the same time while forcibly lowering the vacuum piston 23 supported by the ejector spring 24a on the lower die 5 to force the work 27 The ejector pin 24, which was closing the molding part, is guided to the coupling hole 25 at the same time as the vacuum piston 23 and descends to generate a vacuum suction force in the molding part of the die 21.

이와 같이 상금형(3)이 프레스기의 슬라이드부(2) 작동에 의하여 하강을 하면서 워크(27)를 컵 형상의 제품으로 성형을 하게 되고, 프레스기의 슬라이드부(2) 상승작동에 따라 상금형(3)이 하금형(5)으로부터 분리 상승하면, 다이(21)에서 성형된 제품은 이젝터스프링(24a)의 복원 탄성에 의하여 진공피스톤(23)의 상승과 동시에 이젝터핀(24)에 의해 상부로 취출되는 것이다.Thus, while the upper die 3 is lowered by the operation of the slide unit 2 of the press, the work 27 is molded into a cup-shaped product, and the upper die ( When 3) rises from the lower die 5, the product formed in the die 21 is raised upward by the ejector pin 24 at the same time as the vacuum piston 23 is raised by the restoring elasticity of the ejector spring 24a. It is taken out.

이상에서 상세히 살펴 본 바와 같이 본 발명에서 제공하는 진공흡입 디프-드로잉 성형용 금형(1)은 주로 컵 형상으로 디프-드로잉 성형되는 제품을 성형할 시에 사용되는 것으로서,As described in detail above, the vacuum suction deep-drawing mold (1) provided by the present invention is mainly used when molding a product to be deep-drawn molded into a cup shape,

본 발명은 컵 형상의 제품을 성형하는 다이(21)의 성형부를 기밀스트리퍼(13)와 진공피스톤(23) 및 씰패킹(19,20,23a,26)에 의해 진공 흡입 상태로 만들면서 상금형(3)이 하강 시에 동시 하강하여 워크(27)를 가압하는 가이드펀치(12)에 의해 워크(27)를 진공 흡입 가압 성형토록 함으로써 단 1회의 진공 흡입 가압 성형공정에 의해 컵 형상의 제품을 성형할 수 있으며, 그로 인하여 종래 디프-드로잉 성형공정에서 수회의 가압성형 공정에서 발생하는 재료의 가공경화, 터짐, 스크래치 등과 같은 다수의 결함을 극복할 수 있고, 특히 5회 이상의 순차 성형으로 만들어 질 수 밖에 없는 제품의 성형도 가능한 것이다.According to the present invention, the molding portion of the die 21 for forming a cup-shaped product is made into a vacuum suction state by the airtight stripper 13, the vacuum piston 23, and the seal packings 19, 20, 23a, and 26. (3) When the lowering is simultaneously lowered by the guide punch 12 for pressurizing the work 27 to vacuum suction press molding, the cup-shaped product is formed by only one vacuum suction press molding process. It can be molded, thereby overcoming a number of defects such as hardening, bursting, scratching, etc. of materials generated in several press molding processes in the conventional deep-drawing molding process, and in particular, can be made by five or more sequential moldings. It is also possible to mold products that can only be found.

그리고 본 발명은 성형공정의 단축으로 인한 프레스 및 다이 등과 같은 장치의 수명연장 및 인력절감, 생산성 향상 및 경제적인 파급효과도 매우 다대한 발명이다.In addition, the present invention is a very large invention that extends the lifespan, reduces manpower, improves productivity and economic ripple effect of a device such as a press and a die due to the shortening of the molding process.
