[0026] The movable mold 2 can be driven by the regulating component to regulate the upper and lower positions, so that the entire mold can be opened, which is convenient for taking out the model inside it and improving the overall molding efficiency of the model. The injection molding partition 5 is used to separate the assembly valve body injection molding groove 4, so that the two assembly valve body injection molding grooves 4 are independent of each other, thereby molding two assembly valve shells of the ball valve. The two assembly valve shells can be assembled into a ball valve body after the valve core is installed between them. After the assembly valve shell is molded into a rough shape, the injection molding partition 5 is cooled by the cooling component to improve the heat dissipation and cooling effect of the model, making the model easier to shape. After the molding is completed, the movable mold 2 is lifted by the regulating component, and the injection molding partition 5 is flipped and rotated, so that the model can be conveniently taken out. Since the model is cooled and cooled, the high temperature of the model will not cause damage to personnel.

[0027] An injection channel 6 is provided in the mold base 1 and the movable mold 2, an injection port 7 is provided in the two injection grooves 4 of the assembled valve body, and the two injection ports 7 are respectively connected to the corresponding injection channels 6, a connecting groove 8 is provided on the mold base 1, and the connecting groove 8 is connected to the injection channel 6 opened in the mold base 1, a connecting head 9 is fixed to the bottom surface of the movable mold 2, the connecting head 9 is plug-fitted with the connecting groove 8, and the connecting head 9 is connected to the injection channel 6 opened in the movable mold 2, an injection connector 10 is fixed on the movable mold 2, an injection pipe 11 is connected to the injection connector 10, and the injection connector 10 is connected to the injection channel 6 opened inside the movable mold 2.

[0028] With the above structure, after the mold base 1 and the movable mold 2 are overlapped and fitted, the connector 9 and the connecting groove 8 are buckled together, and then the plastic solution is injected into the injection channel 6 through the injection pipe 11, and then injected into the injection groove 4 of the assembled valve body through the injection port 7, thereby realizing the injection molding work.

[0035] The working principle of the utility model is as follows: the regulating screw 15 is driven to rotate by the driving motor 16, and the regulating screw 15 will drive the movable mold 2 to move downward after rotating. When the mold base 1 and the movable mold 2 are overlapped and fitted, the connector 9 and the connecting groove 8 complete the buckle fit, and then the plastic solution is injected into the injection channel 6 through the injection molding pipe 11, and then injected into the injection molding groove 4 of the assembled valve body through the injection molding port 7. When the injection molding is completed, the coolant can be input into the injection molding partition 5 through the liquid pump 13, so as to absorb heat and cool the injection molding partition 5, and further cool the model in the injection molding groove 4 of the assembled valve body through the injection molding partition 5 to assist molding. After the valve shell is molded, the movable mold 2 can be lifted, and then the injection molding partition 5 is driven by the servo motor to perform a flipping action, so that the injection molding partition 5 is in a vertical state, so as to facilitate personnel to collect the model in the injection molding groove 4 of the assembled valve body or adhered to the injection molding partition 5.
