Description

Technical Field

[0001] The utility model relates to the field of automobile moulds, in particular to a stamping fixing frame for automobile moulds. Background Art

[0002] The stamping device for automobile molds is one of the key equipment in the automobile manufacturing process. It is mainly used to stamp the stamped parts into the shape of automobile parts. This stamping device is usually composed of upper and lower molds, a stamping machine and a control system. The shape and design of the upper and lower molds are determined according to the parts to be produced. During the stamping process, the stamped parts are placed between the upper and lower molds, and then the stamping machine applies huge pressure to deform the stamped parts and form them into the required shape.

[0003] In the stamping process of stamping parts, since the stamping parts are subjected to a relatively large impact force, they will move or bounce during stamping, affecting the quality of automobile parts. Therefore, it is necessary to use a fixing frame to clamp the stamping parts. The existing fixing frames generally fix the stamping parts by clamping both sides of the stamping parts. However, this fixing method is unstable and cannot accurately position the stamping parts. There is still a possibility of being bounced. Utility Model Content
