A v-method mold for casting household appliance mold billets

Abstract

The invention discloses a V-method mold for casting an electronic appliance mold casting blank, and relates to the technical field of aluminum alloy casting. The V-method mold comprises a V-method mold body, wherein the mold body consists of independent combined mold blocks; each combined mold block is subjected to three-dimensional forming and design according to mold drawing requirements; the combined mold blocks are adhered to both sides so as to form the mold body; a plurality of vent holes for vacuuming are formed in the combined mold blocks. The mold casting blank of an inner container of a refrigerator is produced by using a V-method casting process, not only is the energy saved, is the consumption reduced, and is the working intensity alleviated, but also the factory environment is improved, and the V-method is an economic, environment-friendly and green project.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting, in particular to a method for casting a blank of a household appliance mold by a V method and a mold by the V method, and is particularly suitable for casting a blank of a mold for an inner container of a household appliance. Background technique [0002] Existing home appliance liner molds are all sand casting. Firstly, the inner and outer wooden molds are made according to the drawings and casting requirements, and the inner and outer wooden molds are respectively placed in clay sand to obtain the same clay sand inner mold and clay After the sand mold and clay sand mold are dried, the clay sand mold is closed and the smelted aluminum solution is injected. After the aluminum solution is fully solidified, the mold blank is removed for deburring and sand cleaning. Due to the complex shape of the refrigerator liner mold, the outer surface can be demoulded normally up and down, but th...

Problems solved by technology

Because the V method has the advantages of good casting appearance quality, high precision, reducing environmental pollution, and improving the working environment of the workshop, it has been developed rapidly in recent years; but the V method casting process is only suitable for castings with simple structure and easy demoulding. For parts that are difficult or impossible to demould, some manufacturers adopt the method of lowering the resin sand core, which increases the consumption of raw materials and production time, and the surface of the billet inner cavity cannot achieve the advantages that the V method should have.

And limited by the extension ability of the mask, when the film is covered, the film cannot be covered in place in the deep cavity and the corners are easily damaged
