Rapid cooling device for precise plastic mold forming

The utility model provides a quick cooling device for precise plastic mould forming, which relates to the technical field of plastic moulds and comprises a worktable, a support frame is mounted on the upper surface of the worktable, a lower mould block is mounted in the middle of the upper surface of the worktable, and an air cylinder is mounted in the middle of the upper surface of the support frame. The output end of the air cylinder is connected with the upper end of the pressing rod, and a rapid cooling mechanism is installed in the workbench. After raw materials enter the forming cavity through the feeding pipe, the water pump and the conveying pipe convey a water source into the cooling groove and the guiding groove, the temperature of the upper module and the lower module is taken away through flowing of water flow in the cooling groove and the guiding groove, and the raw materials in the upper module, the lower module and the forming groove are cooled and dissipated; and meanwhile, the situation that
