DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the operation of the existing molding sand temperature control mechanism is first introduced.

[0021] In the existing casting production process, the temperature of the molten metal will be transferred to the molding sand after pouring, and the temperature of the molding sand is cooled by natural heat dissipation. This heat dissipation method reduces the production speed and is prone to deformation in the irregularly shaped cavity of the casting. Therefore, regulating the temperature of the molding sand is the preferred solution to solve deformation and low production efficiency.

The water outlet pipe 5 is fixedly connected to the upper end of the left side of the annular water conduit 2, and the ends of the water outlet pipe 5 pass through the outer surface of the casting mold 1 respectively. The connecting seat 6 is fixedly connected to the surface of the right side of the casting mold 1. The voltage-stabilizing tube 7 is fixedly connected to the connecting seat 6.

The provided connecting seat 6 is used to support the voltage-stabilizing tube 7. When in use, The pressure water pump 8 pressurizes the cooling water in the tap water or other water storage structures, and then pumps it into the pressure-stabilizing tube 7 through the pressure water pipe 9.
