Production mold for bumper

Abstract

The invention discloses a production mold for a bumper. The production mold includes a frame body, a lower mold is fixedly connected to the inner wall of the bottom of the frame body, a positioning groove is formed in the top of the lower mold, a molding groove is formed in the middle of the positioning groove, the two ends of the molding groove and the two ends of the positioning groove are symmetrically provided with two second matching grooves, a hydraulic cylinder is fixedly connected to the top inner wall of the frame body, an upper mold is fixedly connected to the bottom of the hydrauliccylinder through bolts, and a pressing mold is fixedly connected to the bottom of the upper mold. The production mold is provided with a connecting rod, a limiting block, a lifting plate, the secondmatching grooves and the like, after products are subjected to compression molding, the finished products are lifted from the interior of the molding groove while the upper mold is lifted, the production processes are simplified, the labor hours are shortened, and the production efficiency is greatly improved. By arranging a serpentine cooling pipe, water is guided into the cooling pipe through acirculation device, it can ensure that the lower mold is maintained at a lower working temperature, and the service life of the lower mold is prolonged.

Description

technical field [0001] The invention relates to a die-casting mold, in particular to a production mold for a bumper. Background technique [0002] Automobile bumper is a safety device that absorbs and slows down external impact and protects the front and rear of the car body. It is generally composed of three parts: outer panel, buffer material and beam. Among them, the outer plate and buffer material are made of plastic, and the beam is stamped with a cold-rolled sheet with a thickness of about 1.5 mm to form a U-shaped groove; the outer plate and buffer material are attached to the beam, and the beam is connected with the longitudinal beam of the frame by screws. disassembled. [0003] In the production process of the beam in the existing bumper production mold, additional tools are required to remove the molded product from the mold, which increases the working hours and affects the production efficiency, and the raw material will produce a lot of deformation when pressi...

AI Technical Summary

Problems solved by technology

[0003] In the production process of the beam in the existing bumper production mold, additional tools are required to remove the molded product from the mold, which increases the working hours and affects the production efficiency, and the raw material will produce a lot of deformation when pressing. Heat, continuous work for a long time will cause the mold to be heated and affect the service life of the mold
