Description

Technical Field

[0001] This invention relates to a temperature control device for independent control of high and low temperature fluids by switching between two temperatures. Background Technology

[0002] The existing die casting process is divided into cold mold and hot mold stages. In the cold mold stage, an external medium is needed to heat the mold. In the hot mold stage, the temperature during heating is much lower than the temperature of the mold flow channel. The medium absorbs heat to cool the mold. However, traditional equipment can only be used to cool the mold by constantly passing through the heat exchanger of the main unit, which is inefficient. Summary of the Invention

[0003] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a temperature control device for independent control of high and low temperature fluids by switching between two temperatures.

[0004] The technical solution of this invention is: a temperature control device for independent control of high and low temperature fluids by switching between two temperatures, including a heat medium interface, a refrigerant interface, a temperature control device, and a client mold. The temperature control device includes an integrated water circuit board, which is equipped with a cold water return valve mounting seat, a hot water return valve mounting seat, a hot water outlet valve mounting seat, and a cold water outlet valve mounting seat. The heat medium interface is connected to the hot water outlet valve mounting seat and the hot water return valve mounting seat, and the refrigerant interface is connected to the cold water outlet valve mounting seat and the cold water return valve mounting seat. Multiple on / off control valves are installed on each of the cold water return valve mounting seat, the hot water return valve mounting seat, the hot water outlet valve mounting seat, and the cold water outlet valve mounting seat. The client mold is connected to the temperature control device.

[0005] Furthermore, the heat medium interface is connected to the hot water outlet valve mounting base and the hot water return valve mounting base through the heat medium outlet channel and the heat medium return channel, respectively, and the refrigerant interface is connected to the cold water outlet valve mounting base and the cold water return valve mounting base through the refrigerant outlet channel and the refrigerant return channel, respectively.

[0006] Furthermore, the inlet of the client mold is connected to multiple client inlet channels, and the on / off control valves of the hot water outlet valve mounting base and the cold water outlet valve mounting base are connected to the client inlet channels; the outlet of the client mold is connected to multiple client return channels, and the on / off control valves of the cold water return valve mounting base and the hot water return valve mounting base are connected to the client return channels.

[0007] Furthermore, the temperature control device also includes a return water temperature sensor and a pressure sensor. The return water temperature sensor is installed on the return water channel at the client end, and the pressure sensor is installed on the inlet water channel at the client end.

[0008] Furthermore, a cold water inlet / outlet bypass pipe is connected between the cold water return valve mounting base and the cold water outlet valve mounting base, and a hot water inlet / outlet bypass pipe is connected between the hot water return valve mounting base and the hot water outlet valve mounting base.

[0009] Furthermore, when the client mold is in the cold mold preheating stage, the on / off control valves of the hot water return valve installation seat and the hot water outlet valve installation seat are opened, and the client mold is heated.

[0010] When the die-casting machine is performing hot mold die casting, when the return water temperature sensor detects that the client mold is in a heating state, the on / off control valves of the hot water return valve and the hot water outlet valve are opened. When the return water temperature sensor detects that the client mold is in a cooling state, the on / off control valves of the cold water return valve and the cold water outlet valve are opened. The adjustment is made according to the process requirements of different molds.

[0011] The advantages of using the temperature control device for independent dual-temperature switching control of high and low temperature fluids provided by this invention are as follows:

[0012] It can improve the cooling efficiency of the heating module, facilitate equipment temperature control, and meet the dual requirements of heating and cooling in the injection barrel within one cycle;

[0013] This can greatly optimize the energy consumption of the equipment.

[0014] This greatly reduces the number of pipes required for equipment operation, reduces upfront investment costs, and lowers pipe heat dissipation. Attached Figure Description
