[0025] First plastic groove 316 is formed in the upper end face of fixed mould 31, first communication pipe 313 is embeddedly installed in the fixed mould 31 outside first plastic groove 316, and the end of first communication pipe 313 away from fixed mould 31 is communicated and installed with cooling liquid tank 1;

[0026] A second shaping groove 326 is provided on the lower end face of the moving mold 32. A second connecting pipe 322 is embedded in the moving mold 32 outside the second shaping groove 326. The end of the second connecting pipe 322 away from the moving mold 32 is connected to the coolant tank 1.

[0027] Specifically, the coolant tank 1 forms a closed-loop cooling system through the inlet pipe 11, connecting hose 13, second connecting pipe 322, and first connecting pipe 313. When the circulation pump 12 is started, the coolant circulates within the system, cooling the first molding groove 316 of the fixed mold 31 and the second molding groove 326 of the moving mold 32. This method avoids directly immersing the high-temperature mold in water, thus reducing the generation of high-temperature steam. The design of the first connecting pipe 313 and the second connecting pipe 322 inside the mold ensures the flow path of the coolant. Simultaneously, the sealing effect of the first sealing gasket 315 and the second sealing gasket 325 prevents coolant leakage. This design not only improves cooling efficiency but also ensures the stability and safety of the mold during the cooling process. The connecting hose 13 is connected to the inlet pipe 11 and the second connecting pipe 322 at both ends using quick-connect fittings, allowing the coolant circulation path to be quickly established or disconnected. This design is easy to operate and improves work efficiency. Unlike existing technologies that directly immerse high-temperature molds in water, this device indirectly cools the mold through an internal circulating cooling system. This method not only avoids the generation of high-temperature steam but also reduces thermal stress caused by rapid temperature changes in the mold, thereby extending its service life. In summary, this device, by incorporating an internal circulating cooling system, achieves rapid cooling of the mold after molding, while avoiding the generation of high-temperature steam and the resulting safety hazards caused by the cooling of the high-temperature mold.
