Abstract

The invention discloses a high-strength steel plate thermoforming mold, which comprises an upper mold base and a lower mold base matched with each other, a guide column is arranged in the middle of the lower mold base, the guide column and the lower mold base are integrally formed, and a lower mold base is movable on the guide column. The mold body, the guide column and the lower mold body form a molding cavity. A matching molding plate is installed in the molding cavity. A pressure cylinder is installed on the upper mold base facing the molding cavity. The size of the material plate is the same as that of the molding cavity. There are a number of positioning pins on the lower mold base, and a number of matching fixing holes on the upper mold base. There are several lifting devices between the lower mold body and the lower mold base. Connected with the same motor drive, a number of elastic parts are arranged inside the lifting device. The invention has simple structure, convenient use, can form products with different thicknesses, can be taken out quickly after forming, saves time and effort, and improves the forming efficiency of steel plates.

Description

technical field [0001] The invention belongs to the technical field of molds, and in particular relates to a high-strength steel plate thermoforming mold. Background technique [0002] Due to the rapid development of the automobile industry, the lightweight of automobiles and the application of high-strength steel have gradually become the development direction. The use of high-strength steel plates to manufacture body parts and reinforcements can significantly improve the strength of body components and enhance the safety performance of automobile collisions. Reduce the amount of material used in parts and reduce the weight of the car body, thereby realizing the lightweight of the car. The traditional cold stamping process can hardly shape the part. Hot stamping forming technology is a forming method specially used to manufacture high-strength steel stamping parts. Its main principle is to preheat the steel stamping parts above the austenitization temperature, and then rap...
