When the equipment is in use, the user starts the servo motor, and then the servo motor operates the converter. When the converter operates, it drives the coolant in the outlet pipe and the inlet pipe to circulate. When the coolant circulates, it flows in the cooling groove inside the lower template to quickly cool down the lower template.

[0025] Specifically, one end of the cooling groove 61 is fixedly connected to the water inlet pipe 63 , and one end of the water inlet pipe 63 away from the cooling groove 61 is fixedly connected to the hose 67 .

[0026] In this embodiment, by providing the cooling groove 61, the cooling liquid can flow through the interior of the lower template 1, thereby reducing the difficulty in rapidly cooling the interior of the lower template 1 when the device is in use.

[0027] Specifically, the hose 67 is fixedly connected to the surface of the water tank 68 , and the surface of the converter 64 is fixedly connected to the servo motor 65 . The servo motor 65 is provided to facilitate applying power to the converter 64 .

[0028] Specifically, a base 66 is fixedly connected to the surface of the servo motor 65 , and the base 66 is fixedly connected to the side of the lower template 1 . The base 66 is provided to facilitate the limiting of the servo motor 65 .

[0029] In this embodiment: a lifting device 7 is provided on the surface of the bottom plate 4, and the lifting device 7 includes a butt plate 71 and a connecting frame 73, the connecting frame 73 is fixedly connected to the lower surface of the bottom plate 4, the butt plate 71 is provided on the surface of the bottom plate 4, the upper surface of the connecting frame 73 is fixedly connected to a cylinder 72, one end of the cylinder 72 is fixedly connected to the surface of the butt plate 71, and the upper surface of the butt plate 71 is fixedly connected to a butt rod 74.

[0031] Specifically, a stop hole 76 is provided inside the lower template 1 , and the stop rod 74 is slidably connected to the inner wall of the stop hole 76 . The stop hole 76 is provided to facilitate the limiting of the stop rod 74 .

[0032] Specifically, a spring 75 is sleeved and connected to the surface of the push rod 74 , and both ends of the spring 75 are fixedly connected to the surface of the push plate 71 and the surface of the lower template 1 respectively. The spring 75 is provided to facilitate the application of a restoring elastic force to the push rod 74 .

[0033] Working principle: When the equipment is in use, the operator needs to install the equipment at the place where it is used, and then the upper and lower templates 1 are combined, the limit column 5 is combined with the inner wall of the lower template 1, and the liquid material is poured into the upper template 2, and then the liquid material fills the groove inside the lower template 1 to form a poured object. When the equipment is in use, the user starts the servo motor 65, and then the servo motor 65 operates the converter 64. When the converter 64 operates, it drives the coolant in the water outlet pipe 62 and the water inlet pipe 63 to circulate. When the coolant circulates, it flows in the cooling groove 61 inside the lower template 1, and the lower template 1 is quickly cooled down. By setting the cooling device 6, the lower template 1 is effectively cooled down, which plays a role in quickly cooling the lower template 1, reducing the equipment.

[0034] When the equipment is in use, the user starts the cylinder 72, and then the cylinder 72 moves to drive the push plate 71 to move. When the push plate 71 moves, it drives the push rod 74 to move. The movement of the push rod 74 drives the spring 75 to displace and deform to generate elastic force. When the push rod 74 moves, the push rod 74 lifts the injection molded part and separates it from the lower template 1. By setting the lifting device 7, the shaped material can be effectively taken out, which plays the role of taking out the material, reduces the situation that when the equipment is in use, the material inside the lower template 1 is tightly fitted after the equipment is cooled, making it difficult for the operator to quickly take out the material, thereby improving the practicability of the equipment.
