Description

Technical Field

[0001] The utility model specifically relates to the technical field of sheet metal processing molds, in particular to a sheet metal processing mold. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology. Sheet metal parts are indispensable in daily life. Sheet metal parts are made by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, and precision welding.

[0003] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its most notable feature is that the thickness of the same part is consistent.

[0004] Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. They have been widely used in the fields of electronics, communications, automotive industry, medical equipment, etc. For example, sheet metal parts are an indispensable component in computer cases, mobile phones, and MP3s.

[0005] At present, traditional sheet metal parts are usually formed by stamping during processing. However, after stamping, the sheet metal parts are still inside the mold, which makes it inconvenient to take out the sheet metal parts. In addition, when traditional stamping equipment is stamping sheet metal parts, the two molds are separated, which causes an offset between the two molds when stamping the sheet metal parts.

[0006] In view of the above situation, we provide a sheet metal processing mold. In this device, when the upper mold cooperates with the lower mold, the guide plates fixedly installed at both ends of the upper mold are inserted into the grooves starting from the ends of the first lower mold and the second lower mold. The inclined surface on the guide plate cooperates with the inclined surface in the groove of the lower mold to achieve the cooperation between the first lower mold and the second lower mold, effectively ensuring the cooperation of the mold grooves opened on the first lower mold and the second lower mold, thereby realizing effective processing of the sheet metal. Utility Model Content

[0007] The purpose of the utility model is to provide a sheet metal processing mold. When processing the sheet metal, the upper mold moves downward, and the two lower molds are controlled to move toward the center by the guide plates at both ends of the upper mold. When the first lower mold and the second lower mold are matched, the plug column at the end of the first lower mold is inserted into the slot of the second lower mold, effectively realizing the molding of the mold groove and ensuring the processing of the sheet metal by the mold; so as to solve the problems of the above-mentioned background technology.
