AI Technical Summary

Problems solved by technology

The bubbles not only affect the mechanical properties of the casting, but also reduce the strength of the product; in addition, if there are bubbles on the assembly surface of the casting, the bubbles will also affect the assembly of the parts. Therefore, when casting aluminum alloy structural parts, the quality of the casting should be improved , the mold must be fully sealed
However, when casting aluminum alloy structural parts, the mold cannot be fully sealed, in other words, the airtightness of the mold is not high

Abstract

The invention provides a sealing system of a vacuum high-pressure casting mold of an aluminum alloy structural member. The casting mold comprises a movable mold frame and a fixed mold frame, wherein a movable mold insert with a cavity is mounted in the movable mold frame; a fixed mold insert with a cavity is mounted in the fixed mold frame; the sealing system of the vacuum high-pressure casting mold at least comprises a sealing structure between the mold frames, a sealing structure between the inserts, a sealing structure between the inserts and the mold frames, a sealing structure of an ejection mechanism, and a sealing structure between a cylinder and a mold; and the sealing structures can prevent air from entering the cavities, so that the mold is totally sealed, and the product quality can be improved.

Description

technical field [0001] The invention relates to a vacuum high-pressure casting mold of an aluminum alloy structural part, in particular to a sealing system of a vacuum high-pressure casting mold of an aluminum alloy structural part. Background technique [0002] There are many types of casting. According to the molding material, casting can be divided into special casting with natural mineral sand and stone as the main molding material (such as investment casting, mud casting, shell casting in foundry, negative pressure casting, solid casting, ceramic casting) etc.) and special casting with metal as the main casting material (such as metal casting, pressure casting, continuous casting, low pressure casting, vacuum high pressure casting, gravity casting, etc.). Vacuum high pressure casting is different from gravity casting and low pressure casting. The filling speed of gravity pouring and low pressure casting is relatively slow, so there is enough time for the filled aluminu...
