The lower circulation pipe 16 is connected to the conveying pipe 11. The upper end of the tee 9 is fixedly connected to a flexible hose 10. The upper circulation pipe 15 is connected to the flexible hose 10. The flexible hose 10 is made of soft material. The tee 9, the flexible hose 10, and the conveying pipe 11 are located on the left and right sides of the upper mold plate 7 and the lower mold base 8.

[0023] Specifically, the base plate 1 serves as the foundation of the entire device, providing stable support and fixing other components (such as the support column 2, the lower mold base 8, etc.). The support column 2 connects the base plate 1 to the mounting plate 3, and the mounting plate 3 provides a horizontal mounting surface. The water tank 17 stores cooling water, providing a stable water source for the system. The water volume is monitored by a liquid level sensor, and water is automatically replenished or drained to maintain the system pressure balance. The water pump 18 provides cooling water circulation power to ensure that the water flow speed meets the heat dissipation requirements. The filter 19 removes impurities (such as rust chips and particles) from the cooling water to prevent blockage of pipes or heat exchanger 20. The tee 9 diverts the cooling water and simultaneously supplies water to the upper circulation pipe 15 and the lower circulation pipe 16. The hose 10 connects the tee 9 to the upper circulation pipe 15, allowing the pipe to deform when the upper mold plate 7 moves. The delivery pipe 11 connects the tee 9 to the lower circulation pipe 16, transmitting cooling water to the lower mold base 8. The connecting pipe 21 connects the water tank 17, water pump 18, filter 19, heat exchanger 20, and other components in series to form a complete cooling circuit.

An electric telescopic rod 6 is fixedly connected to the lower surface of the top plate 5. An upper mold plate 7 is fixedly connected to the lower end of the electric telescopic rod 6. An upper circulation pipe 15 is provided inside the upper mold plate 7. A lower mold seat 8 is fixedly connected to the upper surface of the base plate 1. A lower circulation pipe 16 is provided inside the lower mold seat 8. A cavity is provided inside the upper mold plate 7 and the lower mold seat 8.

A limit port is fixedly connected to the lower surface of the base plate 1. The upper mold plate 7 is located directly above the limit port.

[0025] Specifically, the base plate 1 serves as the foundation of the entire device, providing stable support and fixing other components (such as the support column 2, the lower mold base 8, etc.). The support rod 4 connects the base plate 1 and the top plate 5 to form a frame structure, supporting the movement of the upper mold plate 7. The electric telescopic rod 1 6 drives the upper mold plate 7 to rise and fall vertically, realizing the mold closing and opening with the lower mold base 8. The upper mold plate 7 and the lower mold base 8 cooperate to form a cavity, extruding and shaping the polyurethane foam. An internally integrated upper circulation pipe 15 is used for cooling, and a lower circulation pipe 16 is fixed inside the lower mold base 8. An extrusion inlet 13 is provided on the rear surface to allow the polyurethane foam to enter the mold cavity after extrusion. The electric telescopic rod 2 12 drives the internally set The push plate 14 is used for demolding. During operation, the electric telescopic rod 6 drives the upper mold plate 7 to descend and close with the lower mold base 8 to form a cavity. Polyurethane raw material is injected into the cavity through the extrusion port 13 to fill the space. The water pump 18 is started, and the cooling water circulates through the water tank 17 → filter 18 → heat exchanger 19 → tee 9 → hose 10, delivery pipe 11 → upper circulation pipe 16, lower circulation pipe 15 → water tank 17, absorbing the heat of polyurethane to solidify it. After that, the electric telescopic rod 6 drives the upper mold plate 7 to rise and reset, and the electric telescopic rod 12 drives the push plate 14 to push the solidified product out of the lower mold base 8, thus completing one production cycle.

[0026] Working principle: The base plate 1 serves as the device base, and a stable frame is constructed with the top plate 5 through the support rod 4, providing support for the movement of the upper mold plate 7. During operation, the electric telescopic rod 1 6 drives the upper mold plate 7 to descend, tightly closing with the lower mold seat 8 to form a cavity. Polyurethane raw material is injected through the extrusion inlet 13 and fills the cavity. Then, the water pump 18 starts, and cooling water flows out from the water tank 17, passing through the filter 18 for purification and the heat exchanger 19 for cooling. Then, it is divided through the tee 9, and enters the upper circulation pipe 15 in the upper mold plate 7 and the lower circulation pipe 16 in the lower mold seat 8 through the hose 10 and the delivery pipe 11, respectively. The cooling water circulates in the pipes, absorbing the heat released when the polyurethane raw material is cured, accelerating its molding. After the polyurethane is completely cured, the electric telescopic rod 1 6 drives the upper mold plate 7 to rise and reset. At the same time, the electric telescopic rod 2 12 pushes the push plate 14 forward, smoothly ejecting the cured product from the lower mold seat 8. This completes a full production cycle, realizing the efficient extrusion and water-cooled jacket shaping of polyurethane foam.
