Stamping die for automobile casting

Abstract

The invention discloses a stamping die for an automobile casting. The stamping die includes an upper die and a lower die. The upper die includes an upper cover plate, an upper die base and an upper template which are sequentially and fixedly connected from top to bottom. The lower die includes a lower supporting plate, a lower die base and a lower template which are sequentially and fixedly connected from bottom to top. The upper template is provided with a punch, and the lower die base is provided with a punched hole matched with the punch. An outer guide column and an outer guide sleeve which are matched are respectively arranged between the upper die and the lower die. A group of guide auxiliary mechanisms is further arranged between the upper die and the lower die, the guide auxiliarymechanisms include guide rails and guides elements, the guide rails are installed on the end face of the inner side of the outer guide sleeve, and the guide elements are installed on the upper template and matched with the guide rails. According to the stamping die, the structure is reasonable, and the guide auxiliary mechanisms are arranged on the inner sides of the outer guide column and the outer guide sleeve for guiding and limiting the force with which the outer guide column is inserted into the outer guide sleeve, so that the degradation of the die stability caused by the wear of the guide column and the guide sleeve is effectively avoided, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for automobile castings. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Most of the stamping dies in the prior art rely on the guiding effect of the guide post and the guide sleeve to complete the mold opening and closing. Due to repeated use, the wear of the guide post and the guide sleeve will lead to a decrease in the stability of the mold and directly affect the product quality. [0003] Therefore, in order to solve the above-mentioned existing problems, the present invention provides a new technical solution. Contents of ...
