Automotive thermoforming mold

Abstract

The invention discloses a vehicle thermal forming mold. The vehicle thermal forming mold is provided with a positive punching sectional face forming unit; the positive punching sectional face forming unit is provided with an upper mold seat, a lower mold seat, an upper mold core and a lower mold core, wherein the upper mold core is fixedly installed in the upper mold seat, the lower mold core is fixedly installed in the lower mold seat and matched with the upper mold core; and a local negative angle forming unit is fixedly installed between the upper mold seat and the lower mold seat, and the part negative angle forming unit is matched with the positive punching sectional face forming unit to act. According to the vehicle thermal forming mold, the defect that simultaneous punching forming of an inner sectional face and a local negative angle of the thermal forming mold for a vehicle part cannot be simultaneously achieved in an existing thermal forming mold is overcome, production space, personnel, equipment and energy sources are saved, the scrapping risk caused by cracking or poor quality of the parts is lowered, and producing cost is greatly reduced; and meanwhile, one-time forming operation is simple, safe and reliable, and precision and stability of the parts are greatly improved.

Description

Technical field [0001] The invention relates to the technical field of automobile thermoforming, in particular to an automobile thermoforming mold. Background technique [0002] Automobile thermoforming mold is a mold made in proportion to the shape and structure of a certain object. It uses a pressing method to make metal material into a certain shape. For the production process of automobile hot-formed parts, the boron steel plate of 500~600Mpa is generally heated to about 920 degrees, and then transferred to the automobile hot-forming mold for one-time stamping, and quenched in the mold to obtain the final hot-formed part . If existing automobile thermoforming molds require auto parts to be formed in place at one time, the auto parts must have no negative angles during the design process, otherwise the auto parts cannot be formed in place at one time. Such as figure 1 Shown is an existing automobile thermoforming mold 10, which has an upper mold base 11 and a lower mold base...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the fact that the automobile thermoforming mold in the prior art cannot realize the simultaneous stamping and forming of the inner surface of the thermoforming mold and its local negative angle, and needs to adopt two processes of positive stamping surface forming and local negative angle stamping forming to complete , it is easy to cause the waste of auto parts, the quality is difficult to control, and the equipment investment and energy are increased. The purpose is to provide an auto thermoforming mold that can realize the simultaneous stamping of the inner surface of the thermoforming mold and its local negative angle.
