Description

Technical Field

[0001] The present application relates to the technical field of casting molds, and in particular to an aluminum alloy riser-free casting mold. Background Art

[0002] A casting mold is a material that is made of other easily formed materials in advance to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part's structure. A flowing liquid is then poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold is formed.

[0003] Casting molds are particularly widely used. Aluminum alloys also need to be cast using casting molds. When casting aluminum alloys, in order to prevent bubbles from forming during pouring, the casting mold is usually designed with a riser. However, after the current casting mold is used to cast aluminum alloys, the riser volume of the aluminum alloy casting is large and needs to be cut and removed later, which reduces the production efficiency of the aluminum alloy. To this end, we propose an aluminum alloy riser-free casting mold to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide an aluminum alloy riser-free casting mold to solve the problems raised in the above background technology.

[0012] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0013] The aluminum alloy riser-free casting mold can discharge bubbles generated by pouring aluminum alloy liquid through the slide holes through the two slide holes provided in the movable mold, which will enhance the casting effect of the aluminum alloy casting. The cylinder provided in the fixed groove and the cooperation with the cutting plate can push the riser material at the slide hole, which will quickly remove the riser material from the surface of the aluminum alloy casting, and form an aluminum alloy casting without riser material. This solves the problem that after the current casting mold is used to cast aluminum alloy, the riser material of the aluminum alloy casting is large in volume and requires a troublesome process of cutting and removing it later, thereby improving the production efficiency of the aluminum alloy.
