Problems solved by technology

[0002] At present, many injection molding companies use the cooling tower circulation system to cool the injection molds. Since the cooling water cools the mold, the water temperature will increase significantly. After the high-temperature water directly enters the cooling tower, the water temperature in the cooling tower will increase. The workload of the large cooling system will affect the subsequent cooling effect; there is also a direct discharge of the cooled high-temperature water, resulting in waste of water resources and water costs

Embodiment 1

[0020] like figure 1 As shown in the figure, a circulating water cooling method for injection molds is used. Specifically: according to the size of the mold 6, a cooling water pipe 5 is provided, and the cooling water pipe includes a main water inlet pipe 51, a plurality of branch water inlet pipes 53 (in this embodiment, four branch water inlet pipes are taken as an example) and a main water inlet pipe 53. The water outlet pipe 52, the multiple water inlet pipes 53 are arranged in parallel, one end of which is connected to the main water inlet pipe 51, and the other end is connected to the main water outlet pipe 52. The main water inlet pipe 51 passes through the mold water inlet pipe 4 and the cooling tower. The water outlet pipe 3 is connected to the water outlet of the cooling tower, the main water outlet pipe 52 is connected to the water inlet pipe of the heat exchanger 1, and the water outlet of the heat exchanger 1 is connected to the water inlet of the cooling tower. ...

Abstract

The invention relates to a cooling method of circulating water for an injection mold. According to the cooling method, high-temperature water in the injection mold is introduced into a heat exchanger so as to be subjected to heat exchange; afterwards the water is inputted into a cooling tower so as to be cooled; then the water returns into the injection mold. Compared with the prior art, the cooling method has the advantages of cost saving, efficiency increase, stability, reliability and the like.

Description

technical field [0001] The invention relates to a cooling method of circulating water, in particular to a cooling method of circulating water used for injection moulds. Background technique [0002] At present, many injection molding companies use the cooling tower circulation system to cool the injection mold. After the cooling water cools the mold, the water temperature will be greatly increased. After the high-temperature water directly enters the cooling tower, the water temperature in the cooling tower will increase, increasing the The work load of the large cooling system will affect the subsequent cooling effect; there are also direct discharges of the high-temperature water after cooling, resulting in waste of water resources and water costs. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a cost-saving, efficient, stable and reliable circulating water cooling method for injection molds in order to overcome the above-mentioned d...
