Description

Technical Field

[0001] This article belongs to the technical field of punching dies, specifically an integrated direct punching die for matching upper and lower cover plates. Background Art

[0002] In today's fiercely competitive market, the speed with which a product is launched often determines a company's success or failure. Molds are high-tech, highly efficient production tools. The upper and lower covers of the camera distribution box are complex structures, requiring multiple bending steps to complete, while also ensuring the precise positioning of each mounting hole.

[0003] The existing upper and lower cover plates of the distribution box need to be provided with several installation punching holes on the outer surface due to their own shape and structure. The punching method of each installation punching hole is to punch the holes after the product is formed due to the structure and shape of the upper and lower cover plates themselves. Some holes are on the inclined surface of the product. For the holes on the inclined surface of the product, the mold must be designed with an oblique punching method. Some holes are on the plane and some are on the inclined surface of the product, and there are position requirements for each other. In order to ensure the accuracy of the installation punching holes, they need to be punched out at the same time. Utility Model Content

[0004] In order to solve the above problems, this paper proposes an integrated direct punching die with matching upper and lower cover plates, and the left and right sides of the inner side between the upper die and the lower die of the punching die are respectively provided with a lower cover plate and an upper cover plate, and the outer sides of the lower cover plate and the upper cover plate are provided with a plurality of horizontal holes and inclined holes, and an inclined punch is provided above the plurality of inclined holes, and a vertical punch is provided above the horizontal holes. The inclined punch includes an upper pad block, a splint block, a demoulding block, a spring, a punch and a lower die block. The upper pad block is embedded in the upper die, and the lower surface of the upper pad block is connected to the splint block with an inclined surface. The bottom center of the splint block is protruding with a punch, and springs are provided on both sides of the bottom surface of the splint block. The outer side of the input block is connected to the demoulding input block through a spring. The center of the demoulding input block is penetrated by a punch, and the punch is arranged above the inclined hole. The lower support of the inclined hole is provided with a lower mold input block. The lower surface of the upper pad input block is parallel to the surface of the inclined hole. The punching method of each installation hole of the product is solved by an integrated mold. Since each installation hole is punched after the product is formed, some holes are on the inclined surface of the product. For the holes on the inclined surface of the product, the mold adopts an oblique punching method through an oblique punch. Some of the products are on the plane and some are on the inclined surface. There are position requirements for each other. The inclined hole and the flat surface are punched out at the same time to ensure the position accuracy between each other.

[0005] The punching die includes an upper die and a lower die. The upper die surface is fixedly provided with an upper pad block, a clamping plate block, a demoulding block, a spring and a punch. The lower die surface is provided with a cover plate support seat. The lower die block is provided below the outer horizontal hole and the inclined hole position of the cover plate support seat. By connecting the part of the upper part of the inclined punch with the punch to the upper die, and the lower die block with a hole is provided on the lower die, it can not only facilitate the support of the cover plate, but also have the effect of discharge.

[0006] The upper die is stacked from top to bottom with an upper die base, an upper pad, a fixed plate, a stop plate and a stripping plate. The lower part of the upper pad is horizontally fixed and connected with an upper pad block. The interiors of the fixed plate and the stop plate are concave and embedded with an upper pad block, a clamping plate block and a demoulding block. The interior of the stripping plate is embedded with a demoulding block. By obliquely embedding the inclined punch inside the upper die, an integrated downward pressing movement is achieved when the upper die is displaced, thereby achieving the inclined punching operation.

[0007] The lower die is stacked from top to bottom with a lower template, a lower pad, a lower backing plate and a lower die base. The upper surface of the lower die base is provided with a cover plate support seat, and the interior of the lower die plate is concave and embedded with a lower die entry block. By arranging the lower die entry block on the outside of the cover plate support seat, the punching and discharge of the punch can be realized, and the mounting ears with mounting holes on the outside of the cover plate can also be supported to ensure the stable operation of the entire die.

[0008] The upper cover plate and the lower cover plate are both folding plate type bent cover plates, and the left and right ends of the upper cover plate and the lower cover plate are provided with inclined holes, the rear center of the upper cover plate is provided with a plane hole, the front side of the upper cover plate is symmetrically provided with inclined holes, and the rear center of the lower cover plate is provided with a plane hole. The plane holes of the upper cover plate and the plane holes of the lower cover plate are both symmetrically arranged above the lower mold. By mirroring the front and rear sides of the upper cover plate and the lower cover plate with the plane holes facing outward, it is achieved that the upper cover plate has an inclined hole on one side, which can be conveniently installed with an inclined punch, which is convenient for the installation of the overall mold equipment.

[0009] Beneficial effects:

[0010] The punching method of each installation punching hole of the product is solved by using an integrated mold. Since each installation punching hole is punched after the product is formed, some holes are on the inclined surface of the product. For the holes on the inclined surface of the product, the mold adopts an oblique punching method through an oblique punch. Some holes on the product are on the plane, and some are on the inclined surface. There are position requirements for each other. The oblique surface and the flat surface are punched out at the same time to ensure the position accuracy between each other.

[0011] The mold is a common mold for two products, one for two, saving a set of molds, reducing development costs, and ensuring that the punching surface of the hole is at a perpendicular angle to the product surface, ensuring the accuracy of subsequent position measurement. All punching holes are punched out together to ensure the position requirements between each hole.

[0012] By connecting the upper part of the inclined punch with the punch head to the upper die, and arranging the lower die block with a hole on the lower die, it can not only facilitate the support of the cover plate, but also achieve the effect of discharge.

[0013] By arranging the lower die block on the outside of the cover plate support seat, the punching and discharge of the punch can be realized, and the mounting ears with mounting holes on the outside of the cover plate can be supported to ensure the stable operation of the entire mold.

[0014] By mirroring the front and rear sides of the upper and lower cover plates with plane holes facing outward, the upper cover plate has an inclined hole on one side, which can be easily installed with an inclined punch, facilitating the installation of the entire mold equipment.
