Description

Technical Field

[0001] The utility model relates to the technical field of cover sand molds, and more specifically to a grey ductile iron bearing cover sand mold structure. Background Art

[0002] A covered sand mold generally refers to a mold used in the casting process. It consists of two parts, called the upper cover and the lower mold. This mold is used to form the outer shape of the casting during the casting process. Covered sand molds can be made of different materials, such as sand, metal or other materials suitable for casting. During the casting process, molten metal is poured into the sand mold and cooled and solidified to form the desired casting. Covered sand molds are particularly useful in making castings with complex shapes because they can achieve casting of complex internal spaces by splitting the mold;

[0003] After searching, the existing patent number is: CN201020254186.0. The sand box frame is placed on the sand box bottom plate, and the main body sand core is placed in the sand box formed by the sand box frame and the sand box bottom plate; a functional sand mold is arranged above the main body sand core. The engine cylinder head sand mold of the utility model is composed of a simple sand box composed of a sand box frame and a sand box bottom plate, and a functional sand mold arranged above the main body sand core to form a simple engine cylinder head sand mold. The manufacturing process is simple and no external mold is required. The sand mold manufacturing of the cylinder head sample in the production trial stage can be flexibly arranged, which can effectively improve the trial production efficiency of the sample parts, shorten the product trial production cycle, and does not affect the normal production of the product sand mold arrangement of the assembly line; the amount of molding sand used is small, which saves costs. The inventor found that the prior art has the following problems in the process of realizing the utility model:

[0004] The existing cover sand mold is manually placed with sand powder. After the placement of the sand powder, the excess sand powder is removed and pressed manually. When processing the sand powder, the sand powder inside the cover sand box is often different in tightness due to the difference in manual construction, which in turn affects the casting quality during the casting process.

[0005] Therefore, in view of the above problems, a grey ductile iron bearing cap sand mold structure is proposed. Utility Model Content
