Problems solved by technology

One is to divide it into several small pieces and put them together manually to work inside the product. This method is time-consuming and is not suitable for automated production and can only be placed manually
The other is an oblique slider that can slide up and down. Although it does not need to be placed manually, it can shrink when sliding up and down along the waistline of the isosceles triangle. When sliding to the bottom of the waistline of the isosceles triangle, the slider Parts produced with large gaps have defects in appearance

Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0033] Such as Figure 1 to Figure 10 As shown, the shrinkable core structure that can shrink horizontally and has no missing material on the edge includes a power wheel 6 and a guide block 7, the guide block 7 is arranged parallel to the power wheel 6, and the guide block 7 is located on the side of the power wheel 6 On the top, a shrinking assembly S is arranged on the top of the guide block 7 . Wherein, the power wheel 6 drives the shrinking assembly S, so that the shrinking assembly S expands or contracts.

[0034] The circumferential direction of the power wheel 6 is evenly provided with four through arc-shaped power guide grooves 61, the g...

Abstract

The invention discloses a shrinkage mold core structure capable of horizontally shrinking and free of material shortage at the edge. The shrinkage mold core structure comprises a power wheel and a guide block, wherein, the guide block is parallel to the power wheel, the guide block is located above the power wheel, a shrinkage assembly is arranged above the guide block, and the power wheel drives the shrinkage assembly, so that the shrinkage assembly expands or shrinks. According to the shrinkage mold core structure, when a mold core works, the outer circle can be shrunk to be small in size, and no large gap exists in the peripheral shape when the mold core is reset; due to the fact that the gap is small, the quality of a machined product is guaranteed, and the automatic production is achieved; and no too large gap exists between the spliced mold core sliding blocks, and produced parts do not have appearance defects.

Description

technical field [0001] The invention relates to a stamping part tool, more precisely, a shrinkage mold core structure capable of shrinking horizontally and without material shortage at the edge. Background technique [0002] In the existing production of stamping parts, the process of flanging cylindrical or special-shaped cylindrical parts to the cylindrical shape needs to be installed with a mold core. The function of the mold core makes the product column wall not shrink inward and flanging after the product is turned inward. The surface is smoother, and the edges are even and beautiful in appearance. The existing mold cores are divided into two situations. One is to divide it into several small pieces and put them together manually to work inside the product. This method is time-consuming and is not suitable for automated production and can only be placed manually. The other is an oblique slider that can slide up and down. Although it does not need to be placed manually...
