Die-casting die for new energy automobile brake booster oil cylinder and using method

Abstract

The invention discloses a die-casting die for a new energy automobile brake booster oil cylinder and a using method. The die comprises an upper die plate (10) and a lower die plate (20). An upper mold block (30) is detachably inlaid in the center position of the lower surface of the upper die plate (10), and a lower mold block (40) is detachably inlaid in the center position of the upper surface of the lower die plate (20). The upper mold block (30) and the lower mold block (40) are both provided with cavities. The lower die plate (20) is further provided with a plurality of core-pulling mechanisms. The core-pulling mechanisms are located at the side face position of the lower mold block (40). The upper die plate (10) is provided with a feeding inlet (11), and the feeding inlet (11) communicates with the cavity of the lower mold block (40). By means of the die-casting die for the new energy automobile brake booster oil cylinder and the using method, inner cavities and all inner holes of the new energy automobile brake booster oil cylinder can achieve direct die-cast formation by means of the die, the subsequent working allowance is reduced, subsequent working efficiency is improved, and processing cost is also reduced.

Description

technical field [0001] The invention relates to a die-casting mold and a using method, in particular to a die-casting mold and a using method of a brake booster oil cylinder of a new energy vehicle, and belongs to the technical field of parts forming in the machinery manufacturing industry. Background technique [0002] New energy vehicle brake booster cylinder is an important part in the braking system of new energy vehicles. Such as Figure 5 with Image 6 Shown is a schematic diagram of the parts of the new energy vehicle brake booster cylinder. The cylinder body of this part has an inner cavity, and there are multiple connecting columns on the cylinder body for connecting pipelines. Each connecting column is provided with an inner hole. The production of this part belongs to mass production. The traditional production method is to adopt casting molding. The inner cavity of the cylinder body and the inner hole in the connecting column of the cast-molded part cannot be ca...

AI Technical Summary

Problems solved by technology

The production of this part belongs to mass production. The traditional production method is casting molding. The inner cavity of the cylinder body and the inner hole in the connecting column of the cast-molded part cannot be cast out. It is a solid blank. The machining allowance Large, which brings great trouble to subsequent processing, low efficiency of subsequent processing and high processing cost
