Then start the motor 17, which is the power source of the entire fixed device. After starting, it can convert electrical energy into mechanical energy to provide power for the movement of subsequent parts. The start of the motor 17 makes the gear 15 rotate. The gear 15 plays a role in transmitting power and changing the mode of movement in this system. It converts the rotary motion of the motor 17 into linear motion through meshing with the rack 14.

After the liquid enters the upper mold 4 and the lower mold 7, it is used to accelerate the molding of the raw material, and through heat exchange with the high-temperature raw material and the mold wall inside the mold, the liquid absorbs a large amount of heat, causing the raw material to cool and solidify rapidly, thereby shortening the molding cycle and improving production efficiency. The liquid sent into the mold will return to the inside of the water tank 18 through the fixed pipe 24 connected with the water tank 18, and take away the heat inside the mold. The fixed pipe 24 plays the role of a reflux channel in the circulation process of the liquid, smoothly guiding the liquid that has absorbed the heat of the mold back to the water tank 18. The water tank 18 serves as a storage container for the cooling liquid, providing sufficient liquid reserves for the entire cooling system. The liquid returned to the water tank 18 releases heat and balances temperature in the water tank 18, waiting to be pumped out by the water pump 20 for the next cycle. Through such a cycle, the cooling system can continuously provide low-temperature liquid for the mold, constantly taking away the heat inside the mold, maintaining the mold at an appropriate temperature range, ensuring the smooth progress of the injection molding process, and improving product quality and production efficiency.

[0037] Working principle: when using the device, the lower mold 7 with internal core pulling is placed above the fixed frame 10, then the motor 17 is started, the start of the motor 17 makes the gear 15 rotate, the gear 15 is engaged with the rack 14, then the two side racks 14 move, then the sliding block 13 moves in the side wall of the sliding groove plate 12, the movement of the sliding block 13 drives the clamping jaw 16 to slide in the horizontal groove 11, with the movement of the clamping jaw 16 into the fixed plate 9 to fix it, the lower mold 7 is fixed.

[0038] Then start the hydraulic rod 3 to make it drive the upper mold 4 to move down, the guide column 6 enters the connecting hole 8 inside with the movement of the upper mold 4, so that the upper mold 4 and the lower mold 7 are closed, then the raw material is injected into the mold through the injection port 5, at this time the water pump 20 is started to pump out the liquid inside the water tank 18 through the output pipe 21, and then the liquid is sent to the cooler 19 inside through the conveying pipe 22, and the liquid inside the water tank 18 is cooled by the cooler 19. The cooled liquid is sent to the connecting pipe 23 through the fixed pipe 24, and then sent into the inside of the upper mold 4 and the lower mold 7 through the connecting pipe 23, which is used to accelerate the molding of the raw material. The liquid sent into the mold will return to the inside of the water tank 18 through the fixed pipe 24 connected with the water tank 18, and take away the heat inside the mold. The new liquid enters the mold again to achieve circulation.
