Example Embodiment
[0059] Example 1
[0060] Such as figure 1 As shown, a mold that can realize rapid cooling and rapid heating includes a control unit connected to the injection molding machine, a water pump, a heating element, a temperature sensor, an electric control water valve, an electric control air valve, and an electric control unit. The control air valve is connected to the pressure regulating filter and the water / air pipe connection joint through the air pipe. The electric control water valve is connected to the water pump and the water / air pipe connection joint through the water pipe. The water / air pipe connection joint is installed in the cooling insulation hole and the heat insulation cooling hole. The upper part is connected with the cooling heat insulation hole and the heat insulation cooling hole; the pressure regulating filter is connected with the compressed air pump through the air pipe. The temperature of the mold when heating the cooling rod and the heating rod is 60°C to 500...
Example Embodiment
[0066] Example 2
[0067] Such as Figure 5 As shown, the difference from Embodiment 1 is that the heating and cooling rod body 31 is cylindrical, the section of the heating element accommodating hole 32 is a sector with a central angle less than 180°, and the section of the cooling and heat insulation hole 33 is a sector with a central angle greater than 180°. , The cooling and heat insulation hole 33 surrounds the heating element receiving hole 32 from three directions. The temperature sensor 34 is arranged at one end of the heating and cooling rod body 31 and extends into the heating and cooling rod body 31.
Example Embodiment
[0068] Example 3
[0069] Such as Image 6 As shown, the difference from Embodiment 1 is that the heating and cooling rod body 41 is cylindrical, the section of the heating element accommodating hole 42 is similar to a semicircle, and the cross section of the cooling heat insulation hole 43 is similar to a semicircle, and the cross section of the cooling heat insulation hole Larger than the cross section of the heating element.
