[0016] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] See also Figure 1 The present invention discloses a device for cooling and shaping a wax mold, comprising a motor 1, a gear 2, a counterweight 3, a lifting chain 4, a water tank 5, a temperature probe 6, a circulating water pump 7, a lifting platform 8 and a heater 9;

[0018] A heater 9 is provided at the bottom of the water tank 5, and a temperature measuring probe 6 is provided on the side of the water tank 5;

[0019] The circulating water pump 7 is connected to the water tank 5. Under the action of the circulating water pump 7, the water temperature in the water tank 5 tends to be consistent.

[0020] A gear 2 is provided on the top of the water tank 5, the motor 1 drives the gear 2, the lifting chain 4 cooperates with the gear 2, one end of the lifting chain 4 is connected to the counterweight block 3, and the other end is connected to the lifting platform 8;

[0021] In order to better monitor the water level line 10 , a liquid level meter (not shown) may be installed on the water tank 5 .

[0022] In terms of cooling, the present invention realizes different temperature reduction curves through the PID algorithm of the controller.

[0023] In terms of water pressure shaping, the present invention makes the wax model be placed at different water levels (maximum 1 meter) by means of lifting and lowering, so as to achieve different water pressures on the wax model.
