Cutting die for cylinder body sprues of air-conditioner compressor

Abstract

The invention discloses a cutting die for cylinder body sprues of an air-conditioner compressor. The cutting die comprises an upper die body, a lower die body, a guiding device and a limiting device,wherein the guiding device and the limiting device are arranged between the upper die body and the lower die body. An upper cutting knife, a lower cutting knife, a pressing die and a supporting die are arranged between the upper die body and the lower die body. A cylinder body of the air-conditioner compressor is arranged between the pressing die and the supporting die. The upper cutting knife andthe lower cutting knife are arranged between the first sprue and the second sprue. A spring is arranged at the top of the pressing die. A limiting block is arranged at the bottom of the upper die body. The pressing die is arranged in the limiting block. The spring is arranged between the pressing die and the upper die body. A flange used for preventing the limiting block from disengaging from thelimiting block is arranged at the top of the pressing die. By adoption of the cutting die, traditional manual operation is replaced, automatic cutting of the two cylinder body sprues of the air-conditioner compressor can be achieved in a die, the production efficiency is improved, and the requirement for scale production is met; and meanwhile, cut openings can be prevented from being torn, so that the cutting smoothness of the sprues is improved, and the phenomenon of excessive cutting is prevented.

Description

technical field [0001] The invention relates to an air-conditioning compressor cylinder gate cutting die. Background technique [0002] The die-casting process mainly includes six stages: mold closing, filling, cooling, mold opening, and demoulding. These 6 stages directly determine the molding quality of the product, and these 6 stages are a complete continuous process. [0003] Filling phase: [0004] Filling is the first step in the entire die-casting cycle, starting from the time the die is closed to start die-casting until the die cavity is filled to approximately 95%. In theory, the shorter the filling time, the higher the molding efficiency; but in actual production, the molding time (or die-casting speed) is subject to many conditions. [0005] High speed filling. When filling at high speed, the shear rate is high, and the viscosity of the plastic decreases due to the effect of shear thinning, which reduces the overall flow resistance; the local viscous heating e...

Problems solved by technology

[0053] The purpose of the present invention is to solve the above problems and provide a mold for cutting the gate of the cylinder body of the air conditioner, which replaces the traditional manual operation and can realize the automatic removal of the double gates of the cylinder body of the air conditioner in the mold, thereby improving the production efficiency , to meet the needs of large-scale production; at the same time, it can prevent the tearing of the slit, improve the smoothness of the gate cut, and prevent the phenomenon of excessive cutting
