Description

Technical Field

[0001] This utility model relates to the field of temperature control technology, specifically to an oil-type mold temperature controller. Background Technology

[0002] Oil temperature controllers use thermal oil as the heat transfer medium. An electric heater converts electrical energy into heat energy, and a circulating pump then delivers the thermal oil to the equipment requiring heating, achieving precise temperature control. With industrial development, thermal oil heaters have gradually become an important industrial heating device, applied in various production processes requiring precise temperature control.

[0003] Oil temperature controllers can achieve high-precision temperature control, typically reaching ±1℃ or even higher accuracy, which is crucial for temperature-sensitive production processes. Using heat transfer oil as the heat transfer medium, oil temperature controllers offer high thermal efficiency and heating speed, rapidly transferring heat to the target equipment. However, existing oil-based mold temperature controllers struggle to achieve automatic temperature control in practical use, easily leading to excessively high oil temperatures, thus affecting the normal operation of the controller and limiting its practicality.

[0006] The oil tank has an oil inlet on its side, and a vertical submersible pump, a return oil module, and a cooling water return port are located above the tank. The input end of the vertical submersible pump is located inside the oil tank, and the output end of the pump is connected to the outlet. The vertical submersible pump is used to extract the heat transfer oil from inside the oil tank and discharge it from the outlet.

[0007] The oil tank is equipped with a cooler, a temperature control device, and a heater.

[0021] Please see Figure 1-2 This utility model provides a technical solution: an oil-type mold temperature controller, including a machine body and an oil tank installed inside the machine body.

[0022] The oil tank has an oil inlet 1 on its side, and a vertical submersible pump 4, a return oil module 9, and a cooling water return inlet 7 are installed above the oil tank. The input end of the vertical submersible pump 4 is located inside the oil tank, and the output end of the vertical submersible pump 4 is connected to a discharge outlet 8. The vertical submersible pump 4 is used to extract the heat transfer oil inside the oil tank and discharge it from the discharge outlet 8.

[0023] The oil tank is equipped with a cooler 11, a temperature control device 10, and a heater 12. The temperature control device 10 is located near the top of the oil tank, the heater 12 is located at the bottom of the oil tank, and the cooler 11 is located above the heater 12. A cooling water inlet 6 is located on the top of the unit, which is connected to the refrigerant inlet of the cooler 11. A cooling water return outlet 7 is connected to the refrigerant outlet of the cooler 11. The temperature control device 10 is used to detect the oil level and the temperature of the heat transfer oil inside the oil tank. The cooling water inlet 6 is used to inject cooling water into the cooler 11, and the cooling water return outlet is used to discharge cooling water. The heater 12 is used to heat the oil inside the oil tank.

[0024] Furthermore, a cooling solenoid valve 5 is provided on the cooling water inlet 6, which is used to control the entry of cooling water.

[0025] Furthermore, an over-temperature alarm 2 and a liquid level indicator 3 are provided on one side of the machine body near the top. When the liquid level is insufficient, the liquid level indicator 3 is turned off, and when the liquid level reaches the required level, the liquid level indicator 3 is turned on.

[0026] Furthermore, the temperature control device 10 includes a liquid level float and a temperature sensor. The liquid level float is electrically connected to the liquid level indicator 3, and the temperature sensor is electrically connected to the over-temperature alarm 2, the cooling solenoid valve 5, and the heater 12. The liquid level float is used to detect the liquid level, and the temperature sensor is used to detect the temperature of the heat transfer oil. The switching of the liquid level indicator 3, the over-temperature alarm 2, and the cooling solenoid valve 5 is controlled by an external main control system.

[0027] Furthermore, a liquid level window 13 is provided on the side of the oil tank, which allows for a direct view of the oil level inside the tank.

[0028] Furthermore, the cooler 11 is spirally arranged inside the oil tank. The cooler 11 can use cooling pipes, and the spiral shape of the cooler 11 increases the operating time of the cooling water within the cooler 11.

[0029] In summary, when using this device, heat transfer oil is first injected through the oil inlet 1. When the injected heat transfer oil reaches the equipment's operational requirements, the liquid level indicator 3 illuminates, indicating that the medium is in place and the equipment can operate normally. When the customer starts the equipment's vertical submersible pump 4 and heater 12, the medium enters the equipment requiring temperature control through the outlet 8, and then returns to the oil tank through the equipment's return port module 9. When the equipment needs cooling, the cooling solenoid valve 5 opens, and external cooling water enters through the cooling water inlet 6 into the cooler 11, and then returns to the external circulating water return through the cooling water return port 7, completing the cooling and temperature reduction. This temperature control device 10 includes a liquid level detection and over-temperature alarm device. When the liquid level is low, the liquid level indicator 3 will turn off, indicating insufficient liquid level. When the temperature exceeds the limit, the over-temperature alarm 2 will output an alarm, shut down the heater 12, and automatically open the cooling valve to reduce temperature.

[0030] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
