Embodiment 1

[0023] This preferred embodiment provides an upper mold structure, including an upper mold body and a plurality of balance weights. A plurality of balance weights are respectively arranged at the edge of the bottom surface of the upper mold body, and are arranged symmetrically with respect to the center of gravity of the upper mold body.

[0024] Such as figure 1 As shown, the balance weight 1 is a columnar body with a connecting portion 2 arranged on the top end. The balance weight 1 is movably connected with the upper mold body through the connecting part 2 .

[0025] During use, select the balance block 1 whose height is the same as the thickness of the workpiece to share part of the pressure on the upper die body and avoid deformation of the workpiece.

[0026] When processing a series of workpieces, the thickness of the workpieces may be different, and the required height of the balance weight 1 is also different. The balance weight 1 is movably connected with the uppe...

Embodiment 2

[0028] This preferred embodiment provides an upper mold structure, which is basically the same as the first preferred embodiment. A plurality of balance weights are arranged at the edge of the bottom surface of the upper mold body of the upper mold structure.

[0029] The difference is that: if figure 2 As shown, the balance block 1 includes a fixed block 11 and a movable block 12; the fixed block 11 is provided with a screw 3, and the middle part of the movable block 12 is provided with a screw hole 13; the movable block 12 can move up and down along the screw 3. A detachable pressure sensor is arranged on the bottom surface of the upper mold body.

[0030] During use, the fixed block 11 is fixed at the edge of the bottom surface of the upper mold body. Then rotate the movable block 12 to allow the movable block 12 to move up and down along the screw rod 3 until its height is adjusted to the same thickness as the workpiece.

[0031] In this preferred embodiment, the heigh...

Embodiment 3

[0033] This preferred embodiment provides an upper mold structure, which is basically the same as the first preferred embodiment. A plurality of balance weights are arranged at the edge of the bottom surface of the upper mold body of the upper mold structure.

[0034] The difference is that: if image 3 As shown, the balance weight 1 is composed of at least one balance base block 4; the balance base block 4 is made of magnetic material, and at least two balance base blocks 4 can attract each other.

[0035] The thickness of the balance base block 4 is relatively thin, and a plurality of balance base blocks 4 can be sucked together to form a balance block 1 .

[0036] In this preferred embodiment, the height of the balance block 1 is adjusted by increasing or decreasing the number of balance base blocks 4, so that the height of the balance block 1 is the same as the thickness of the workpiece, and bears part of the pressure of the upper mold body to ensure a better processing ...

Abstract

The invention discloses an upper die structure and belongs to the field of automobile part machining tools. The upper die structure is designed to solve the problem that an existing product can not exert pressure on workpieces evenly. The upper die structure comprises an upper die body and multiple balance blocks, wherein the multiple balance blocks are arranged on the edges of the bottom surface of the upper die body respectively. Each balance block is provided with a connecting part and is movably connected with the upper die body through the connecting part. Each balance block comprises a fixed block and a movable block, wherein a screw is arranged on the fixed block, a screw hole is formed in the middle of the movable block, and the movable block can move up and down along the screw. Each balance block is composed of at least one balance base, wherein each balance base is made of magnetic materials, and at least two balance bases can attract each other. The upper die structure is convenient to use, reasonable in structure, capable of well sharing the pressure of the upper die body, wide in application range, and particularly suitable for the automobile part producing and machining technology.

Description

technical field [0001] The invention relates to an upper mold structure, in particular to an upper mold provided with a balance weight. Background technique [0002] In the production process of auto parts, it is necessary to perform stamping, partial drilling and other processing procedures on high-strength plates. In order to prevent the high-strength plate from being deformed during processing, an upper mold is usually pressed on the high-strength plate, and the area of ​​the upper mold is larger than the workpiece. [0003] The existing upper die has a large area and is heavier, and the uneven pressure distribution formed on the workpiece may cause greater deformation of the workpiece, or reduce the effect of the upper die to inhibit deformation. Contents of the invention [0004] One object of the present invention is to propose an upper die structure that can effectively balance the pressure of the upper die body. [0005] Another object of the present invention is...
