Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a gravity casting mold for an aluminum shell of an automobile brake oil pump. Background Technique

[0002] Gravity casting refers to the process in which molten metal is poured into a mold under the action of the earth's gravity, also known as gravity pouring. Broadly speaking, gravity casting includes sand casting, permanent mold casting, investment casting, lost foam casting, clay mold casting, etc.; narrowly speaking, gravity casting mainly refers to permanent mold casting.

[0003] When gravity casting a shell, for a shell with a protruding outer irregular surface, it is difficult to quickly demold the shell after casting. In order to facilitate demolding, the shell is generally cast in parts and then spliced together. In this way, the shell processing process is more and the shell cannot be integrally formed, and the strength of the finished shell is limited.
