The input pipe 106 is connected to the water pump 105. Through the water pump 105, the cooling water in the water tank 103 can be pumped out and injected into the input pipe 106. The cooling plate 107 is fixedly installed in the mold body 102 by bolts. The cooling plate 107 has a cavity for the circulation of cooling water inside. The input pipe 106 is communicated with the cavity of the cooling plate 107. The cooling water injected into the input pipe 106 can be input into the cavity of the cooling plate 107 and flow. When the mold body 102 is injection-molded, the heat of the rubber product can be transferred to the cooling water flowing in the cooling plate 107. The output pipe 108 is communicated with the cooling plate 107. The cooling water with heat in the cooling plate 107 can be discharged into the output pipe 108.

The cooling water injected into the input pipe 106 can flow into the cavity of the cooling plate 107. The heat of the rubber product can be transferred to the cooling water flowing in the cooling plate 107. The cooling water with heat in the cooling plate 107 can be discharged into the output pipe 108, and the dripping nozzle 109 can drip the cooling water with heat in the output pipe 108 downward from above the fixed frame 104. The cooling fan can blow the outside air into the fixed frame 104 and dissipate the heat of the cooling water dripped by the dripping nozzle 109 through the blown air, so that the heat in the cooling water is transferred to the blown air. Finally, the hot air is discharged through the discharge pipe 110. Thus, the rubber product in the mold body 102 can be quickly cooled by the cooling plate 107, and then it is convenient for the demolding mechanism in the mold body 102 to quickly demold the cooled and formed rubber product.

[0029] When using the demoulding structure of the injection mould for rubber product forming of this embodiment, when the workpiece needs to be cooled after the injection moulding of the mould body 102 is completed, the cooling water in the water tank 103 can be pumped out by the water pump 105 and injected into the input pipe 106. The cooling water injected into the input pipe 106 can flow into the cavity of the cooling plate 107. The heat of the rubber product can be transferred to the cooling water flowing in the cooling plate 107. The cooling water with heat in the cooling plate 107 can be discharged into the output pipe 108, and through the dripping nozzle 109, the cooling water with heat in the output pipe 108 can be dripped downward from above the fixed frame 104. The outside air can be blown into the fixed frame 104 by the cooling fan, and the cooling water dripped by the dripping nozzle 109 can be cooled by the blown air, so that the heat in the cooling water is transferred to the blown air. Finally, the hot air is discharged through the discharge pipe 110, so that the rubber product in the mould body 102 can be quickly cooled by the cooling plate 107, and then it is convenient for the demoulding mechanism in the mould body 102 to quickly demould the cooled and formed rubber product.
