[0002] The air conditioner compressor is the core component of the air conditioner system, and the cylinder body is the main component of the air conditioner compressor. The cylinder body needs to be resistant to high temperature, corrosion and high-strength wear. In the prior art, a casting process is usually used for forming processing of the air conditioner compressor cylinder body. Casting is a machining method for metal liquid to solidify and form under high pressure. The obtained casting has good mechanical properties, and meets the requirements of resistance to high temperature, corrosion and high-strength wear. For the cast cylinder body, demolding is a very dangerous link. The ordinary casting mold in the prior art has small demolding force, and forcibly demolding can easily damage the casting. Therefore, a cylinder body casting mold which is easy to demold and take out the product is needed.

[0003] According to the casting mold of the air conditioner compressor cylinder body provided in the application number 201820976641.4, the technical scheme points include an upper mold, a middle mold and a lower mold, the upper mold, the middle mold and the lower mold constitute a cavity, and the middle mold is designed by a split type through an insert block. When demolding, the middle mold is first separated from each other, which has the effect of reducing damage to the casting during demolding.

[0004] The above-mentioned casting mold, although to a certain extent, solves the problem that the cylinder body is not easy to demold after casting is completed, but still has the problems of loose mold structure and difficulty in taking out the cylinder body with more complex structure. SUMMARY
