Abstract

The invention relates to an improved structure of a GF9 pump cover mold. The structure comprises an upper mold, a lower mold, a first sand mold and a second sand mold, wherein the first sand mold andthe second sand mold are embedded in the upper mold and the lower mold respectively, and an upper groove is formed in a runner of the upper mold. According to the structure, the defective parts of castings can be reduced, the peripheral collision of the castings can be reduced, burrs, generated during machining by a drilling machine, on hole openings can be greatly reduced, and the machining process and the manufacturing cost are reduced.

Description

Technical field: [0001] The invention relates to an improved structure of a GF9 pump cover mold. Background technique: [0002] There will be some problems in the production process of GF9 pump cover, such as the poor water connection on the outer surface of the casting, resulting in defective products of the casting; Need to carry out the burr removal process again); the above-mentioned several problems have increased the processing procedure and the production cost. Invention content: [0003] The purpose of the present invention is to provide an improved structure of the GF9 pump cover mold, which is reasonable in design and beneficial to reduce casting defects and manufacturing costs. [0004] The improved structure of the GF9 pump cover mold of the present invention includes an upper mold, a lower mold and a first sand mold and a second sand mold embedded in the upper mold and the lower mold, and an upper groove is provided on the soup channel of the upper mold.
