Special anti-blockage die-casting die for automobile casting

Abstract

The invention discloses a special anti-blockage die-casting die for automobile casting. The special anti-blockage die-casting die for automobile casting comprises a lower die base, a conveying pipe control valve and a guide column return spring, wherein limit protection vertical columns are arranged at the two ends above the lower die base, and lower die guide columns are arranged on the lower die base and close to the rear parts of the limit protection vertical columns; the guide column return spring is installed on the lower die guide columns; a convex die of the die is arranged at the middle position above the lower die base; convex die fixing bolts are arranged at the junction of the convex die of the die and the lower die base; drawing liquid spraying nozzles are arranged on the lower die base and close to the left end and the right end of the convex die of the die; and drawing liquid conveying pipelines are arranged in the lower die base and close to the lower parts of the drawing liquid spraying nozzles. The drawing liquid spraying nozzles are convenient for spraying a drawing liquid on the surface of a material after the die is used for a period of time to play a lubrication role and reduce a friction force among the material, an upper die and a lower die, thus the material is better separated from the surface of the die.

Description

Technical field [0001] The invention belongs to the technical field of automobile die-casting molds, and in particular relates to an anti-blocking type die-casting mold special for automobile casting. Background technique [0002] When people talk about cars, the first thing they see is the car body. That is to say, the body is the identifying assembly of the car. The body represents the image characteristics of that car. In a narrow sense, automobile mold is the general name of the mold for punching all stamping parts on the automobile body. That is "automobile body stamping die". For example, the cover mold is the main component of the automobile mold, such as the top cover flanging mold, the beam reinforcing plate pressing mold, etc. This type of die is mainly a cold die. In a broad sense, "automobile mold" is the general term for the molds used to manufacture all parts of automobiles. For example, stamping molds, injection molds, forging molds, casting wax molds, glass ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a special anti-jamming type die-casting mold for automobile casting, to solve the problem that the existing automobile die-casting mold mentioned in the background art is prone to jamming during stamping, causing mold damage, prolonging production time, reducing Production efficiency, at the same time, when the impact force of the mold is too large, it is easy to cause cracks on the surface of the product, resulting in an increase in the product scrap rate
