본 발명은 금형의 몰드플레이트에 관한 것으로서, 보다 상세하게는 드로우금형의 캐비티가 일체로 고정되어 프레스에 장착되는 몰드플레이트에 관한 것이다.The present invention relates to a mold plate of a mold, and more particularly, to a mold plate in which a draw mold cavity is integrally fixed and mounted to a press.

도 1은 종래의 드로우 성형과정을 도시한 것으로서, 패널(500)이 투입되면 상형(502)이 하강하여 하측에 고정되어 있는 하형(504)과의 사이에서 패널(500)에 모양을 성형한 후, 성형이 완료된 패널(500)을 취출하도록 되어 있고, 블랭크홀더(506)는 상기 패널(500)의 성형시에 적절한 압력으로 패널(500)을 홀딩하는 역할을 수행하여 패널(500)의 터짐 및 주름을 방지하는 기능을 한다.1 shows a conventional draw molding process, when the panel 500 is inserted, the upper mold 502 is lowered to form a shape in the panel 500 between the lower mold 504 fixed to the lower side. The panel 500 is formed to take out the mold, and the blank holder 506 serves to hold the panel 500 at an appropriate pressure during molding of the panel 500, thereby causing the panel 500 to burst and Prevents wrinkles.

도 2는 상기한 바와 같은 상형(502)과 하형(504) 및 블랭크홀더(506)를 도시한 것으로서, 제품의 형상을 직접 형성하는 캐비티(508)와, 상기 캐비티(508)에 일체로 형성되어 캐비티(508)를 프레스에 장착할 수 있도록 하는 몰드플레이트(510)로 이루어져 있다.FIG. 2 illustrates the upper mold 502, the lower mold 504, and the blank holder 506 as described above. The cavity 508 directly forms the shape of the product, and is integrally formed with the cavity 508. It consists of a mold plate 510 to mount the cavity 508 to the press.

상기 몰드플레이트(510)는 그 대체적인 형상이, 장착되는 캐비티(508)의 외곽을 모두 감싸는 사각형 플레이트의 형상을 가지고 있고, 프레스에 장착하기 위한 장착부가 다수 구비되어 있으며, 단면 구조는 캐비티(508)쪽의 면은 덮여있고, 반대쪽으로는 개방된 다수의 리브구조로 이루어져 있다.The mold plate 510 has a shape of a rectangular plate that generally covers the outer periphery of the cavity 508 to be mounted. The mold plate 510 includes a plurality of mounting portions for mounting to the press, and the cross-sectional structure of the mold plate 510 is a cavity 508. The side on) is covered and the other side is made up of multiple rib structures.

그런데, 상기한 바와 같은 몰드플레이트(510)는 상기 캐비티(508)의 외곽 형상 모두를 단순한 사각형으로 감싸는 구조를 가지고 일체로 형성되어 있고, 상기와 같이 리브구조의 일측이 덮여있는 구조를 가지고 있어서, 그 크기 및 중량이 매우 커서 금형의 제작비용이 많이 소요되고 그 취급이 매우 어려운 문제점이 있다.However, the mold plate 510 as described above is integrally formed with a structure that surrounds all the outer shapes of the cavity 508 in a simple quadrangle, and has a structure in which one side of the rib structure is covered as described above. The size and weight of the mold are very large, and the manufacturing cost of the mold is very high, and the handling thereof is very difficult.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 캐비티를 프레스에 장착하기 위한 필수적인 부분만으로 이루어져서 크기와 중량이 대폭적으로 저감되어 금형 제작비용이 절감되고 취급의 용이성이 향상되도록 한 금형의 몰드플레이트를 제공함에 그 목적이 있다.The present invention has been made to solve the problems as described above, consisting of only the essential parts for mounting the cavity to the press size and weight is greatly reduced to reduce the mold manufacturing cost and ease of handling of the mold The purpose is to provide a mold plate.

이하, 도 3과 도 4를 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 3 and 4.

본 발명에 따른 몰드플레이트(17)는 상하가 관통된 다수의 리브(9)가 격자를 이루어 결합되되, 별도로 제작된 캐비티(1)가 장착되는 캐비티지지부(3)와, 상기 캐비티지지부(3)와 일체로 형성된 장착지지부(7)로 이루어진다.
상기 캐비티지지부(3)는 캐비티(1)의 외곽선을 벗어나지 않도록 캐비티(1)의 외곽선 내에 형성되어 상기 캐비티(1)를 지지한다.
상기 장착지지부(7)는 상기 캐비티지지부(3)의 캐비티(1) 장착면 반대쪽에 일체로 돌출 형성되고, 프레스에 장착되는 장착부(5)가 형성된다.In the mold plate 17 according to the present invention, a plurality of ribs 9 penetrating up and down are combined to form a lattice, and a cavity support part 3 to which a separately manufactured cavity 1 is mounted, and the cavity support part 3. It consists of a mounting support 7 formed integrally with.
The cavity support 3 is formed in the outline of the cavity 1 so as not to deviate from the outline of the cavity 1 to support the cavity 1.
The mounting support 7 is integrally projected on the opposite side to the mounting surface of the cavity 1 of the cavity support 3, and a mounting portion 5 is mounted on the press.

즉, 본 발명의 몰드플레이트(17)는 상기 캐비티(1)를 지지하고 프레스에 장착하는데 필수적인 부분만을 형성하고, 나머지 부분은 제거함으로써, 중량을 크게 저감시키고 크기를 줄일 수 있도록 된 것이다.That is, the mold plate 17 of the present invention forms only an essential part for supporting the cavity 1 and mounting it to the press, and removes the remaining part, thereby greatly reducing the weight and reducing the size.

특히, 상기 리브(9)의 상하측이 모두 관통되도록 구성함으로써, 종래에 비하여 중량을 크게 저감할 수 있도록 하고 있으며, 상대적으로 두꺼운 다수의 주리브(11)와 상대적으로 얇은 다수의 보조리브(13)가 조합되어 형성되도록 함으로써, 가급적 필요로 하는 강도는 유지하면서 중량은 저감될 수 있도록 하고 있다.In particular, the upper and lower sides of the ribs 9 are configured to penetrate, so that the weight can be greatly reduced as compared with the prior art, and a plurality of relatively thick main ribs 11 and a plurality of relatively thin auxiliary ribs 13 are provided. ) Are formed in combination so that the weight can be reduced while maintaining the required strength as much as possible.

다만, 상기 장착지지부(7)는 상기 캐비티(1)의 외곽선을 벗어나게 형성되며, 상기 장착부(5)와 마찬가지로 상기 캐비티(1)의 외곽선을 벗어난 위치에 금형의 이동을 가능하게 하는 운송핀(15)이 설치되도록 하여, 운반용 훅이 걸릴 수 있도록 하고 있다.However, the mounting support 7 is formed outside the outline of the cavity 1, and the transport pin 15 to enable the movement of the mold in a position outside the outline of the cavity 1, similar to the mounting portion 5 ), So that the hook can be caught.

따라서, 도 4에 도시된 바와 같이 몰드플레이트(17)와 캐비티(1)를 결합함으로써 프레스에 장착될 금형이 완성되게 된다.Accordingly, as shown in FIG. 4, the mold to be mounted on the press is completed by combining the mold plate 17 and the cavity 1.

상기한 바와 같이 몰드플레이트(17)가 구비되면 캐비티(1)를 지지하기 위한 충분한 강성을 확보하면서도, 그 중량 및 크기는 종래에 비하여 대폭적으로 저감되어, 금형의 제작 비용을 저감할 수 있고, 그 취급이 크게 용이해지는 효과를 얻을 수 있다.As described above, when the mold plate 17 is provided, while sufficient rigidity for supporting the cavity 1 is secured, the weight and size thereof are greatly reduced as compared with the prior art, and thus the manufacturing cost of the mold can be reduced. It is possible to obtain an effect of greatly ease of handling.

이상과 같이 본 발명에 의하면, 캐비티를 프레스에 장착하기 위한 필수적인 부분만을 상하가 개방된 리브 구조로 형성함으로써, 크기와 중량이 대폭적으로 저감되어 금형 제작비용이 절감되고 금형의 취급이 용이해지는 효과가 있다.According to the present invention as described above, by forming only the essential portion for mounting the cavity to the press in the rib structure with the upper and lower openings, the size and weight are greatly reduced, the mold manufacturing cost is reduced and the handling of the mold is easy have.
