Description

Technical Field

[0001] The utility model belongs to the field of mold temperature controllers, and specifically relates to a mold temperature controller pipeline structure. Background Art

[0002] The pipeline pressure of the existing water-cooled mold temperature controllers on the market cannot be automatically adjusted. The pressure of the refrigerant output by the mold temperature controller is related to the pressure of the external cooling system and the number and flow rate of the equipment connected to the load end of the mold temperature controller. The inlet pressure of the circulating pump is the same as the inlet pressure of the cooling water, which is generally 0.4MPa-0.5MPa. After the pressure is increased by the circulating pump, the outlet pressure of the heat medium reaches more than 0.6MPa. When the flow rate at the load end is small, the outlet pressure of the heat medium can reach 0.7MPa-0.8MPa, which far exceeds the working pressure of the low-pressure insulation tank. The working pressure of the low-pressure insulation tank is generally below 0.4MPa, which can easily cause the insulation tank and pipeline to burst.

DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0021] Figure 1 It is a system structure schematic diagram of the mold temperature controller pipeline structure in the embodiment of the utility model.

[0022] like Figure 1 As shown, the mold temperature controller pipeline structure provided by the utility model includes a heat medium pipeline 10, a cooling water inlet pipeline 20 and a cooling water outlet pipeline 30. The outlet of the cooling water inlet pipeline 20 is connected to the heat medium pipeline 10, and the inlet of the cooling water outlet pipeline 30 is connected to the heat medium pipeline 10. A heater 11 is provided on the heat medium pipeline 10. A pressure regulating component 12 and a circulating pump 13 are provided on the heat medium pipeline 10. The circulating pump 13 is connected to the pressure regulating component 12. The pressure regulating component 12 can adjust the pressure boosting process of the circulating pump 13 according to the heat medium pressure at the outlet of the heater 1. The pressure boosting process of the circulating pump 13 is adjusted by adjusting the motor speed of the circulating pump 13, thereby automatically adjusting the pipeline pressure to avoid the problem of insulation pipe and pipeline bursting.

[0023] The pressure regulating assembly 12 includes a pressure sensor 121 and a frequency converter 122. The pressure sensor 121 is arranged on the heat medium pipeline 10. The pressure sensor 121 is connected to the frequency converter 122. The frequency converter 122 is connected to the circulation pump 13. The frequency converter 122 can adjust the motor speed of the circulation pump 13, thereby adjusting the pressure increase process of the circulation pump 13 to prevent the pipeline pressure from being too high. The pressure sensor 121 is located on one side of the water outlet of the heater 11, and can collect the pipeline pressure on one side of the water outlet of the heater 11, and output a pressure signal to the frequency converter 122. The frequency converter 122 receives the pressure signal and adjusts the motor speed of the circulation pump 13 according to the pressure signal. When the pressure is too high, the motor speed of the circulation pump 13 is reduced; when the pressure is too low, the motor speed of the circulation pump 13 is accelerated, thereby ensuring that the pressure at the outlet of the heat medium pipeline 10 is normal.

[0024] The pressure regulating assembly 12 includes a pressure display 123, which is arranged on the heat medium pipeline 10 and is located on one side of the water outlet of the heater 11. It can directly display the pipeline pressure on the water outlet side of the heater 11, making it convenient for operators to record and grasp the pipeline pressure.

[0025] A safety pressure relief valve 14 is provided at one end of the outlet of the heat medium pipeline 10. The safety pressure relief valve 14 can further protect the pipeline pressure. When the pressure regulating component 12 fails, it can directly release pressure to prevent excessive pressure from entering the low-pressure insulation tank, further avoiding the occurrence of insulation pipe and pipeline bursting problems.

[0026] A high-pressure limiter 15 is provided between the circulation pump 13 and the heater 11. The high-pressure limiter 15 is connected to the circulation pump 13. The high-pressure limiter 15 can limit the pipeline pressure from the outlet of the circulation pump 13, thereby further preventing the circulation pump 13 from over-pressurizing and further avoiding the problem of insulation pipe and pipeline bursting.

[0027] The outlet of the heat medium pipeline 10 is also provided with a first ball valve 41 and a first temperature sensor 42. The first ball valve 41 can control the flow of heat medium at the outlet of the heat medium pipeline 10, and the first temperature sensor 42 can detect the temperature of the heat medium at the outlet of the heat medium pipeline 10; the reflux port of the heat medium pipeline is provided with a second ball valve 43, a second temperature sensor 44 and a heat medium reflux filter 45. The second ball valve 43 can control the flow of heat medium at the reflux port of the heat medium pipeline 10, the second temperature sensor 44 can detect the temperature of the heat medium at the reflux port of the heat medium pipeline 10, and the heat medium reflux filter 45 can filter the heat medium at the reflux port of the heat medium pipeline 10 to prevent pollution and ensure the normal circulation of the heat medium; the first temperature sensor 42 and the second temperature sensor 44 can detect the temperature of the heat medium in the heat medium pipeline 10 to ensure the normal circulation of the heat medium and the normal operation of the mold temperature controller.

[0028] A pressure reducing valve 21 and a water inlet filter 22 are provided on the cooling water inlet pipeline 20. The pressure reducing valve 21 can reduce the pressure of the cooling water in the cooling water inlet pipeline 20 to 0.2MPa, and then enter the circulation pump 13 for pressure boosting, and then pass through the heater 11 for heating, flow through the heat medium pipeline 10, and the pressure sensor 121x collects the pipeline pressure on the water outlet side of the heater 11, and outputs a pressure signal to the frequency converter 122. The frequency converter 122 receives the pressure signal and adjusts the motor speed of the circulation pump 13 according to the pressure signal. When the pressure is too high, the motor speed of the circulation pump 13 is reduced; when the pressure is too low, the motor speed of the circulation pump 13 is accelerated, thereby ensuring that the pressure at the outlet of the heat medium pipeline 10 is normal.

[0029] The cooling water outlet pipeline 30 is provided with a solenoid valve 31 and a water outlet filter 32. The solenoid valve 31 can control the circulation of the cooling water outlet pipeline 30, and the water outlet filter 32 can filter the cooling water in the cooling water outlet pipeline 30 to prevent pollution and ensure the normal circulation of the cooling water.

[0030] The mold temperature controller pipeline structure provided by the utility model also includes a bypass pipeline 50, the end of the bypass pipeline 50 is connected to the heat medium pipeline 10, and both ends of the bypass pipeline 50 are connected to the heat medium pipeline 10. The bypass pipeline 50 can adjust the circulation of the heat medium, thereby facilitating the adjustment of the heat medium pressure in the heat medium pipeline 10, and further avoiding the problem of insulation pipe and pipeline bursting.
