Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a thermostat processing mold. Background Art

[0002] The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, changes the water circulation range, adjusts the heat dissipation capacity of the cooling system, and ensures that the engine works within the appropriate temperature range. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. If the main valve of the thermostat is opened too late, it will cause the engine to overheat; if the main valve is opened too early, the engine preheating time will be extended, causing the engine temperature to be too low.

[0003] During the use of the existing thermostat processing mold, most of the heat is naturally dissipated after the thermostat is cast. The efficiency of natural heat dissipation is slow, which reduces the efficiency of thermostat demoulding and delays the processing time of the next process. Therefore, we have launched a new thermostat processing mold. Utility Model Content

[0013] 1.

By connecting an external cold air source with the air inlet pipe, cold air is sent into the heat dissipation cavity through the air inlet pipe, and the heat in the heat dissipation cavity is discharged through the air outlet pipe. By passing cold air into the heat dissipation cavity for heat exchange, the heat inside the lower mold can be quickly dissipated, the demoulding time of the thermostat can be accelerated, and the next process can be entered more quickly for processing;

[0014] 2.
