Piston casting mold cooling system and piston casting equipment

Abstract

The invention discloses a piston casting mold cooling system which comprises an air compressor, a vortex tube, a control valve bank and a controller, an output port of the air compressor is communicated with a gas inlet of the vortex tube, a low-temperature gas outlet of the vortex tube is connected with a gas inlet of the control valve bank, and a gas outlet of the control valve bank is connected with a cooling flow channel inlet of a casting mold. The controller is in communication connection with the control valve set so as to control low-temperature compressed gas generated by the vortex tube to enter a cooling flow channel of the casting mold. And the cooling speed is increased, and then the piston blank head metallographic structure grade is improved. Corrosion and leakage of cooling water to the mold are effectively avoided, the production efficiency is improved, the manufacturing cost is reduced, the overall performance is improved, compressed gas can be reused, and the workshop production cost is saved to a certain extent. The invention further discloses piston casting equipment comprising the piston casting mold cooling system.

Description

technical field [0001] The invention relates to the field of piston processing, in particular to a cooling system for a piston casting mold. Furthermore, the invention relates to a piston casting plant comprising the system described above. Background technique [0002] In the process of using the casting mold to cast the piston, the casting mold needs to be cooled. The current cooling method is to pass cooling water into the components of the casting mold. The water temperature is above 25°C, and the heat on the mold is taken away by the cooling water. Finally To achieve the purpose of rapid cooling of the mold. [0003] Generally, the faster the cooling rate of the casting, the shorter the solidification time, and the correspondingly denser the structure of the material obtained, the better the performance. However, limited by the structure of the mold, the diameter of the cooling water channel inside the mold cannot be designed too large. In addition, the temperature of...

Problems solved by technology

However, limited by the structure of the mold, the diameter of the cooling water channel inside the mold cannot be designed too large. In addition, the temperature of the cooling water is generally above 25°C, which ultimately leads to the limitation of the cooling speed of the entire mold system.

Due to insufficient cooling capacity of the mold, the solidification time of the blank is too long, and the metallographic structure of the head of the piston blank is not high

When the system cooling pipeline is blocked or leaked, it is not easy to be found, and the manual inspection process is time-consuming. The mold sealing system that has been used for a long time is aging, and the mold is easy to leak water during work, resulting in potential safety hazards.
