Description

Technical Field

[0001] The utility model relates to the technical field of hardware stamping back plate moulds, in particular to a synchronous bending and trimming moulding mould structure. Background Art

[0002] Currently, when trimming and bending the back panel, the edges are trimmed first and then the corners are bent, which results in uneven wavy extrusion and higher folding height. Therefore, after bending, there is another process to trim the two corner edges on the top side again, and an extra set of molds is needed to complete the back panel.

[0003] The existing back panel mold forming process is divided into 7 sets of forming. After bending, there is an additional process of trimming, which occupies one more punch press and increases manpower turnover. First of all, the processing is difficult and the processing volume is large. Secondly, there are many processes, which increase the mold opening cost, machine cost and personnel waste. One more station in turnover is prone to deformation, which increases the risk of scrapping. The mold manufacturing cost and operation are more complicated, which in turn increases the manufacturing cost. Because the mold adjustment time is long when adding a set of molds, the production efficiency is not high. At the same time, the existing back panel mold forming process does not have the function of screening, collecting and processing the waste generated by the back panel trimming, resulting in the waste generated by the back panel trimming falling to the ground, which is not conducive to the operator to recycle the waste generated by the back panel trimming.

When the upper die body 1 punches downward and touches the blade entry block 7 on the lower die body 2, the excess back plate waste is cut off, and the waste generated by the back plate cutting naturally falls down. When the back plate folding edge height is adjusted to be short, the blade entry block 7 moves downward, and the bottom of the lower die bending block 6 is ground according to how much the back plate is short. When the back plate folding edge size is high, the blade entry block 7 moves upward, and the processing part is ground according to how much the back plate folding edge size is high.
