Abstract

The invention relates to a cooling device of injection moulding equipment, and specifically relates to an injection moulding machine cooling system. The system comprises a cooling water inlet port that is connected to the cooling part of an injection moulding machine, a cooling water outlet port, and a refrigerating machine for refrigerating the cooling water. The system also comprises a water storage tank for storing cooling water, a feed pump that is connected to the inlet port and the water storage tank, and a controller for controlling on-off of the refrigerating machine, the temperature sensors of the controller are fixed in the inlet port and the channel of the water storage tank, the outlet port is connected to the water storage tank, and the water inlet and the water outlet of the refrigerating machine are both communicated with the water storage tank. The provided cooling system can solve the problems that in the conventional injection moulding machine cooling system, the temperature of the cooling water is too low, and the energy is wasted, and can provide cooling water with a proper temperature.

Description

Technical field [0001] The invention relates to an accessory of injection molding equipment, in particular to a cooling system of an injection molding machine. Background technique [0002] The refrigerant system is a common refrigeration system, including evaporators, compressors, condensers, expansion valves, and feedwater pumps. PE, PPR, PVC and other pipes need to be cooled by cooling water during the injection molding process. Usually, the refrigeration of the cooling water is completed by the freezer. The structure of the existing cooling system of the injection molding machine is as follows: It includes a refrigerant system connected to the cooling water outlet of the injection molding machine, a water storage tank connected to the refrigerant system, a water pump connected to the water tank, and an injection molding machine connected to the water pump. [0003] The existing cooling system of the injection molding machine has the problem that when the injection molding mac...
