A kind of stamping forming steel plate mold

Abstract

The invention provides a punch forming steel plate mold. The punch forming steel plate mold comprises an upper mold plate, a female mold, a male mold, a lower mold plate, a base, a material supporting plate, a spring and a driving block; the lower end of the base is fixed to the lower mold plate; the material supporting plate is movably arranged at the upper end of the base, the spring is arranged between the material supporting plate and the base, the upper end of the driving block is fixed to the upper mold plate, and the lower end of the driving block is movably matched with the material supporting plate in an inserted manner; by means of the technical scheme, through application of positioning a material supporting portion in a mold structure, two functions of product material supporting and positioning are effectively achieved at the same time, and the problems that before part forming, the gravity center of a product inclines, product containing is unstable, and positioning is unstable, and consequently, product precision consistency is poor are solved; the problem of production potential safety hazards existing in manual material supporting is solved, and meanwhile the production efficiency is improved; in addition, the structure is simple, and implementation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a punching and forming steel plate mould. Background technique [0002] Automobile stamping parts are mostly realized by cold stamping forming. Before stamping and forming, the parts need to be stably and accurately positioned in the mold, and then the mold will be formed with the closing of the press. [0003] However, due to the limitation of the size of the part itself or the product shape structure, the center of gravity of the part (semi-finished product) before forming may not be on the punch body when placed, and the part cannot be placed stably, requiring manual support and positioning, which is inconvenient to operate. If there is no support positioning part in the mold structure, the part will fall over after being placed on the punch in the initial state due to the deviation of its own center of gravity, and cannot be placed stably. Whether the positioning of the part ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a stamping and forming steel plate mold to solve the problems of poor consistency of product accuracy caused by the inclined center of gravity, unstable placement and unstable positioning of the parts before the parts are formed; Low efficiency and potential safety hazards
