Problems solved by technology

[0003] At present, the structure of the inner cavity of the piston of the automobile air compressor is relatively complicated. Usually, there are pits on the pin seat and two reinforcing ribs connected to the top. The demoulding of the inner cavity core cannot be carried out
In addition, the traditional metal casting process is generally used to produce the piston at present, such as gravity metal mold casting, manipulator casting, pressure casting, forging, low pressure casting, etc. The mechanical properties and thermal conductivity cannot meet the needs of the current market development

Embodiment Construction

[0017] like figure 1 Shown: a piston of an automobile air compressor, the side of the piston pin seat is flat, and the inner cavity of the skirt is a cavity.

[0018] like figure 2 , 3, 4, and 5 show: 1 is the upper beam, 2 is the main mooring cylinder, 3 is the unloading rod, 4 is the movable scale, 5 is the upper template, 6 is the reset floating platen, 7 is the floating spring, 8 is the core, 9 is the die, and 10 is the Lower mold outer cover 11 is that bottom mold 12 is that lower template 13 is that bottom mold connecting rod 14 is that workbench 15 is unloading ring.

[0019] The mold used for manufacturing the above-mentioned automobile air compressor piston is characterized in that: it is composed of a "convex" shape core that can form the inner cavity of the piston, a discharge ring, a die that can form the external shape of the piston, and a bottom mold: the core is equipped with The unloading ring, and the gap fit between the unloading ring and the core, the bot...

Abstract

The present invention relates to an automobile compressor piston, including piston pin seat. It is characterized by that side surface of said piston pin seat is made into the form of flat block, the skirt inner cavity is hollow cavity. The die equipment for making automobile compressor piston is formed from convex core for forming piston inner cavity, discharging ring, female die for forming exterior form of the piston and bottom die.

Description

[0001] Field: [0002] The invention relates to a mold used for manufacturing a piston of an automobile air compressor and a manufacturing process for manufacturing the piston of an automobile air compressor by using the mold. Background technique: [0003] At present, the structure of the inner cavity of the piston of the automobile air compressor is relatively complicated. Usually, there are pits on the pin seat and two reinforcing ribs connected to the top. Just can't carry out to the stripping of cavity core. In addition, the traditional metal casting process is generally used to produce the piston at present, such as gravity metal mold casting, manipulator casting, pressure casting, forging, low pressure casting, etc. The mechanical properties and thermal conductivity cannot meet the needs of the current market development. Invention content: [0004] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a k...
