Description

A stamping mold for back plate punching, trimming and marking

technical field

The utility model relates to the technical field of punching, trimming, and engraving molds, in particular to a punching, trimming, and engraving mold for a back plate.

Background technique

Punching, trimming, and engraving are three different processes in the stamping process, and generally require multiple processes to complete. The existing backplane processing technology generally firstly punches the workpiece, then trims the edge of the workpiece, then performs marking, and finally completes the shaping of the workpiece through the shaping mold. Since different production molds are required for different processes, four sets of molds are required to complete the processing of the backplane using the above-mentioned processing technology, resulting in too long production lines, excessive labor intensity, and low production efficiency; at the same time, due to multiple processes Processing will cause the unqualified rate of the product to be too high, greatly reducing the production efficiency of the product and increasing the production cost.

Utility model content

In order to achieve the above purpose, the utility model provides the following technical solutions: a back plate punching edge trimming engraving mold, including an upper mold base and a lower mold base, the upper mold base is provided with an upper template, and the upper mold base The edge is provided with an edge trimming knife, and the edge trimming knife is fixed in the upper mold base by screws, the inner ring of the edge trimming knife is provided with a pressing plate, and the four corners of the upper surface of the pressing plate are provided with guide rods , the press plate is movably installed in the upper die base through a guide rod, and a spring is arranged on the guide rod, and the spring is located between the press plate and the upper die base, and the inner side of the guide rod is on the upper die base. A punch and an engraving assembly are arranged on the die base, and the punch and the engraving assembly are fixed on the lower surface of the upper die base by screws, a lower template is arranged on the lower die base, and a lower template is arranged on the lower die base. There are edge trimming knife grooves and punching grooves corresponding to the positions of the edge trimming knife and the punch.

Preferably, the upper mold base is provided with a limit groove at the position corresponding to the guide rod, the limit groove is a stepped groove, and the top of the guide rod is provided with a limit block suitable for the size of the limit groove .

Preferably, the edge of the edge trimming knife is provided with an irregular zigzag edge.

Preferably, the press plate is provided with a through hole at the position corresponding to the punch, and the press plate is provided with a slot at the position corresponding to the engraving assembly.

Preferably, the bottoms of the trimming sipes and punching troughs are provided with stripping troughs.

Compared with the prior art, the beneficial effect of the utility model is: when the utility model is used, the upper mold base moves downward, firstly, the pressure plate presses the back plate on the lower mold base, and the pressure plate contacts the upper mold base after contacting the back plate. The relative movement of the seat keeps the pressure plate stationary, and the lower die seat moves downward to perform trimming, punching and engraving in sequence. Tool wear, by integrating the punching, edge trimming and marking of the back plate into a set of molds, and simultaneously punching, trimming and marking the back plate workpiece, the scrap rate is reduced, the production efficiency of the product is improved, and the Cost of production.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-2, the utility model provides a technical solution: a back plate punching and cutting edge marking mold, including an upper mold base 8 and a lower mold base 14, and the upper mold base 8 is provided with an upper template 9 , the edge of the upper die base 8 is provided with a trimming knife 3, the trimming knife 3 is fixed in the upper die base 8 by screws, and the inner ring of the trimming knife 3 is provided with a pressing plate 2, so The four corners of the upper surface of the pressing plate 2 are provided with guide rods 4, and the pressing plate 2 is movably installed in the upper mold base 8 through the guide rods 4, and the guide rod 4 is provided with a spring 11, and the spring 11 Located between the press plate 2 and the upper die base 8, the inner side of the guide rod 4 is provided with a punch 6 and an engraving assembly 7 on the upper die base 8, and the punch 6 and the engraving assembly 7 are fixed by screws Set on the lower surface of the upper mold base 8, the lower mold base 14 is provided with a lower template 15, and the lower mold base 14 is provided with a cutting edge corresponding to the positions of the trimming knife 3 and the punch 6. Side siping 1 and punching 13.

The upper mold base 8 is provided with a limit groove 5 at a position corresponding to the guide rod 4, the limit groove 5 is a stepped groove, and the top of the guide rod 4 is provided with a stopper suitable for the size of the limit groove 5.
