During this process, the water pump 8 will drive the condensing agent to circulate in the water pipe, the storage tank 9 and the condensation plate 16, thereby improving the stability of cooling. An inclined groove 17 is provided on the surface of the condensation plate 16, and an insulation board 3 is provided on the surface of the condensation plate 16. A groove 5 is provided on the side surface of the insulation board 3, and a transmission block 10 is fixed to the bottom surface of the insulation board 3. Since the transmission block 0 has the same slope as the inclined groove 17, the condensation plate 16 will slowly rise during the process of pulling out the insulation board 3.

[0027] On the basis of the first embodiment, in order to realize the cooling function of the injection mold, a sliding groove 21 is provided on the inner wall side surface of the mounting groove 20, a through groove 6 is provided on the side surface of the lower mold 2, a slider 11 is fixed on the side surface of the heat insulation board 3, a connecting groove 13 is provided on the surface of the groove 5, an annular groove 12 is provided on the surface of the connecting groove 13, a limit block 4 is provided on the surface of the heat insulation board 3, the limit block 4 is rotated in the groove 5 to release the limit between the heat insulation board 3 and the lower mold 2, and the heat insulation board 3 can be pulled out, a connecting rod 15 is fixed on the surface of the limit block 4, and a rotating block 14 is fixed on the surface of the connecting rod 15;

Since the transmission block 0 has the same slope as the inclined surface groove 17, the condensation plate 16 will slowly rise during the process of the insulation board 3 being pulled out;

[0029] There are multiple groups of slide grooves 21, which are symmetrically distributed on the inner wall side surface of the installation groove 20. There are multiple groups of sliders 11, which are symmetrically distributed on the side surface of the insulation board 3. The sliders 11 correspond to the slide grooves 21.

The condensation plate 16 absorbs the heat of the injection groove to cool the plastic product in the injection groove. During this process, the water pump 8 will drive the condensing agent to circulate in the water pipe, the storage box 9 and the condensation plate 16, thereby improving the stability of cooling. When the injection mold does not need to cool the plastic product during heating, the insulation board 3 is inserted, and the insulation board 3 will prevent the heat of the injection groove from being absorbed by the condensation plate 16. This structure is simple and easy to operate, thereby achieving cooling of the injection mold and improving its use effect.
