Description

Technical Field

[0001] The utility model relates to the technical field of cylinder moulds, in particular to a high-pressure casting mould. Background Art

[0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The air converts thermal energy into mechanical energy by expansion in the engine cylinder; the gas is compressed by the piston in the compressor cylinder to increase the pressure.

[0003] When manufacturing a cylinder, high-pressure casting is generally required. The existing cylinder mold for high-pressure casting generally requires a bottom mold when in use, and then the bottom mold is subjected to stamping and drilling and other processes accordingly. After stamping, the bottom mold is often not firmly fixed, and it is not convenient to replace the bottom mold accordingly in the later stage. At the same time, after the stamping is completed, it is also difficult to demould in the later stage, and it is time-consuming and laborious for the user to operate. In publication number CN213614054U, a cylinder mold for high-pressure casting is proposed. Although it solves the above-mentioned problems of the bottom mold being not firmly fixed and the difficulty in demoulding, when fixing the bottom mold, it is manually fixed by a pressure plate and screws, and the fixing process is cumbersome and inefficient; in addition, when demoulding, only two thin demoulding ejector rods are used for demoulding, and there is uneven force in the process, which is easy to cause damage to the product.
