Metal key forming equipment with multi-layer die plate structure

Abstract

The invention aims to provide metal key forming equipment with multi-layer die plate structure. According to the technical scheme, the forming equipment is composed of a glue injection forming upper die plate, a forming structure die plate and a glue injection forming lower die plate, four die assembly register extension hole columns, a plurality of upper die plate forming structure frames and upper die plate overflow separation grooves are arranged on the glue injection forming upper die plate, two upper die plate glue injection holes are formed in each upper die plate forming structure frame, the forming structure die plate is provided with a forming horizontal groove, the plurality of double-key part forming blocks and four positioning holes, the plurality of double-key part forming dies, a lower die plate overflow separation groove and four die assembly positioning columns are arranged on the glue injection forming lower die plate, and two lower die plate glue injection holes are formed in each double-key part forming die. According to the metal key forming equipment with multi-layer die plate structure, the die is simple in structure, accurate in die assembly and capable of preventing the die from falling off, meanwhile, the upper glue injection forming and the lower glue injection forming, so that the glue injection operation is more uniform, the product is more attractive, the output of inferior products is reduced, the enterprise cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of mold fixtures, in particular to a metal button forming device with a multi-layer template structure. Background technique [0002] Nowadays, for the forming of metal key parts, stamping and injection molding are basically used, and the process is very mature, and the product quality is also guaranteed. However, there are certain defects in the use of general metal key parts, such as regular maintenance. , inconvenient replacement, difficult operation due to key deformation, etc. Therefore, structural improvements need to be made to make up for the above problems. Therefore, metal keys with double-sided rubber parts are applied to actual needs, and the molding mold is also transformed, but the transformation The finished mold is difficult for the overall injection molding. Due to the small size of the button parts, more accurate mold closing is required, and the closing of the injection molding must be satisfied at ...

[0002] Nowadays, for the forming of metal key parts, stamping and injection molding are basically used, and the process is very mature, and the product quality is also guaranteed. However, there are certain defects in the use of general metal key parts, such as regular maintenance. , inconvenient replacement, difficult operation due to key deformation, etc. Therefore, structural improvements need to be made to make up for the above problems. Therefore, metal keys with double-sided rubber parts are applied to actual needs, and the molding mold is also transformed, but the transformation The finished mold is difficult for the overall injection molding. Due to the small size of the button parts, more accurate mold closing is required, and the closing of the injection molding must be satisfied at the same time. In terms of the uniformity of the injection molding, the previous injection molding The process did not achieve the purpose of ensuring the uniform dispersion of the glue, so that the quality of the product is poor, and there is no glue overflow phenomenon. The bottom surface of the button is in direct contact with the control board. If there is glue overflow, it is easy to cause a short circuit. Make the mold precision and product quality need to be guaranteed and improved
