DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] In an exemplary embodiment, Figure 1 As shown, an integrated large thin-wall die casting mold temperature control system is provided, comprising a medium channel 1, a spacer tube 2, a first heating device 3 and a temperature detection device 4. Among them: The medium channel 1 and the spacer tube 2 are arranged inside the mold body 5 .

[0022] A delivery pipeline 6 for the temperature control medium is connected between the first end of the spacer tube 2 and the second end of the medium channel 1, and the second end of the spacer tube 2 is connected to the first end of the medium channel 1 to form a circulation loop. A pump 7 is provided on the delivery pipeline 6, and the pump 7 is used to provide power so that the temperature control medium circulates in the circulation loop.

[0023] The temperature detection device 4 is used to detect the medium temperature value in real time, and the medium temperature value refers to the temperature of the temperature control medium located inside the mold body 5 .

[0024] In the embodiment of the present application, the temperature control system of the die-casting mold of an integrated large thin-walled component (such as an integrated large thin-walled metal / alloy component) is a temperature control system of the die-casting mold of an integrated large thin-walled component. The temperature detection device 4 is used to detect the temperature value of the medium in real time (continuous detection or regular detection at a set time interval) to ensure that its temperature meets the production requirements. The temperature detection device 4 is of various types, and can be a temperature sensor, a thermistor (such as a thermistor, a thermocouple, etc.), a thermometer (such as a glass thermometer, a digital thermometer, etc., which directly displays the temperature reading and is suitable for scenes where the temperature needs to be read intuitively), etc. There is no specific limitation on the installation position of the temperature detection device 4, and it can be set according to actual needs. For example, the temperature detection device 4 is set in the medium channel 1. For example, the temperature detection device 4 is set in the spacer tube 2. For another example, the temperature detection device 4 is set at the first end of the spacer tube 2. For another example, the temperature detection device 4 is set at the second end of the medium channel 1.

[0025] The first heating device 3 is installed on the spacer tube 2. When the medium temperature value is not greater than the first preset temperature value, the first heating device 3 is turned on to heat the temperature control medium flowing through the spacer tube 2; when the medium temperature value is greater than the first preset temperature value, the first heating device 3 is turned off; wherein the first preset temperature value is not less than the minimum temperature value required to heat the mold body 5 to the target temperature.

[0026] For example, the target temperature value is determined to be 40°C according to the molding process, and the temperature value required to heat the mold body 5 to the target temperature is determined by experiments to be 50-80°C, and the first preset temperature value is any value between 50-80°C, such as setting the first preset temperature value to 55°C. The temperature detection device 4 outputs the medium temperature value once every minute. If the medium temperature value output by the temperature detection device 4 for the first time is 30°C, which is less than the first preset temperature value of 55°C, the first heating device 3 is turned on to heat the temperature control medium flowing through the spacing tube 2. If the medium temperature value output by the temperature detection device 4 for the second time is 35°C, the first heating device 3 remains turned on and continues to heat the temperature control medium flowing through the spacing tube 2 until the medium temperature value output by the temperature detection device 4 for the nth time (n is greater than 2) is 58°C, which is greater than the first preset temperature value of 55°C, and the first heating device 3 is turned off. If the temperature of the mold body 5 drops below 55°C after the temperature control medium with a temperature of 58°C is used for heat exchange, the first heating device 3 is turned on again to heat the temperature control medium flowing through the spacer tube 2 until the medium temperature value output by the temperature detection device 4 is greater than 55°C again. Through the above method, it can be ensured that the mold body 5 is heated to 40°C by the temperature control medium after the temperature is increased.

[0027] In the embodiment of the present application, since the mold body 5 is heated by circulating the temperature control medium and performing cyclic heat exchange with the mold body 5, in order to heat the mold body 5 to the target temperature, the minimum temperature value required to heat the mold body 5 to the target temperature should be greater than the target temperature, and the target temperature should not be less than the minimum temperature required when the mold body 5 is used to form the product. For example, when the temperature required for the mold body 5 to form the product is 40 to 60 degrees Celsius, the minimum value of the target temperature is 40 degrees Celsius.

[0028] The temperature control medium circulates in the circulation loop, that is, the temperature control medium circulates the following flow process: from the conveying pipeline 6 into the spacing tube 2, after flowing through the spacing tube 2, into the medium channel 1 from the spacing tube 2, and after flowing through the medium channel 1, flows back from the medium channel 1 to the conveying pipeline 6. When the medium temperature value is not greater than the first preset temperature value, the first heating device 3 is turned on, and the temperature control medium is heated by the first heating device 3 when flowing through the spacing tube 2, so that the temperature rises, and the temperature control medium after the temperature rises enters the medium channel 1 from the spacing tube 2. The temperature control medium entering the medium channel 1 directly contacts the mold body 5. Since the temperature of the temperature control medium is higher than the temperature of the mold body 5, the two perform heat exchange and heat the mold body 5. Since the temperature control medium circulates in the circulation loop, the temperature control medium after the temperature rises performs cyclic heat exchange with the mold body 5, thereby heating the mold body 5. The temperature control medium is a fluid used to transfer heat, which is not specifically limited and can be selected according to actual application requirements. For example, water is used as the temperature control medium, and water as the temperature control medium has the advantages of high thermal conductivity and low cost. For another example, thermal oil is used as the temperature control medium, which has higher thermal stability and a wider temperature control range.

[0029] The temperature control of the mold body 5 is crucial to ensure the molding quality and production efficiency of the product. The internally designed medium channel 1 is used to control the temperature of the mold body 5. The design of the mold body 5 needs to be carried out according to the shape, size and precision requirements of the product and the characteristics of the molding process.

[0030] When the mold body 5 needs to be heated, a medium channel 1 and a spacer tube 2 are arranged inside the mold body 5, a conveying pipeline 6 for the temperature control medium is connected between the first end of the spacer tube 2 and the second end of the medium channel 1, and the second end of the spacer tube 2 is connected to the first end of the medium channel 1 to form a circulation loop; a pump 7 is arranged on the conveying pipeline 6, and the pump 7 is used to provide power so that the temperature control medium circulates in the circulation loop; a temperature detection device 4 is arranged to detect the medium temperature value in real time, and the medium temperature value refers to the temperature of the temperature control medium located inside the mold body 5; a first heating device 3 is arranged on the spacer tube 2, and when the medium temperature value is not greater than the first preset temperature value, the first heating device 3 is turned on to heat the temperature control medium flowing through the spacer tube 2; when the medium temperature value is greater than the first preset temperature value, the first heating device 3 is turned off; since the first heating device 3 is located in the mold The die body 5 is inside the die body 5, so that the temperature control medium is heated inside the die body 5 to make its temperature greater than the first preset temperature value, avoiding the heat loss caused by the excessively long conveying pipeline 6 when the temperature control medium is heated outside the die body 5 and the heated temperature control medium is conveyed to the inside of the die body 5 by the conveying pipeline 6; since the temperature control medium circulates in the circulation loop, and the medium channel 1 is opened inside the die body 5, the heated temperature control medium directly contacts with the die body 5 when circulating through the medium channel 1 for circulating heat exchange; and since the first preset temperature value is not less than the minimum temperature value required to heat the die body 5 to the target temperature, the temperature control medium heated to a temperature greater than the first preset temperature value is used, and the die body (die-casting die) 5 can be heated to the target temperature through circulating heat exchange, thereby improving the quality of the one-piece large thin-walled component formed by the die-casting die.

[0031] In another exemplary embodiment of the present application, in order to ensure uniform heating of the mold body 5 , the spacer tube 2 is disposed inside the medium channel 1 and does not contact the mold body 5 .

[0032] In another exemplary embodiment of the present application, in order to ensure the heating effect of the mold body 5, as Figure 1~2 As shown, the end of the second end of the medium channel 1 and the end of the first end of the spacer tube 2 are both flush with the side wall of the mold body 5, the first end of the medium channel 1 is located inside the mold body 5, the second end of the spacer tube 2 is located inside the medium channel 1, and the portion of the spacer tube 2 disposed inside the medium channel 1 does not contact the mold body 5.

[0033] In the embodiment of the present application, it is necessary to ensure that the spacing between the first end of the medium channel 1 and the side wall of the mold body 5 and the spacing between the first end of the spacing tube 2 and the first end of the medium channel 1 are as small as possible to ensure the heating effect.

[0034] In another exemplary embodiment of the present application, Figure 1As shown, at least one temperature control medium port 8 is provided on the delivery pipeline 6, and the pump 7 is used to provide power so that the temperature control medium entering from the temperature control medium port 8 circulates in the circulation loop.

[0035] In another exemplary embodiment of the present application, the temperature control medium port 8 includes a temperature control medium inlet and a temperature control medium outlet. The temperature control medium inlet is used to input the temperature control medium into the conveying pipeline 6, and the temperature control medium outlet is used to output the temperature control medium from the conveying pipeline 6.

[0036] In another exemplary embodiment of the present application, Figure 2 As shown, the delivery pipeline 6 includes a first pipeline 10 and a second pipeline 11. Among them: The first end of the first pipeline 10 is connected to the second end of the medium storage device 12, and the second end of the first pipeline 10 is connected to the first end of the spacing tube 2. The second end of the second pipeline 11 is connected to the first end of the medium storage device 12, and the first end of the second pipeline 11 is connected to the second end of the medium channel 1. The pump 7 is used to provide power so that the temperature control medium in the medium storage device 12 circulates in the circulation loop.

[0037] In an embodiment of the present application, the medium storage device 12 may be a box for storing a temperature control medium, such as a water tank. The amount of temperature control medium in the medium storage device 12 needs to be guaranteed to fill the circulation loop. There is no specific limitation on the installation position of the pump 7, which can be set according to actual needs. For example, the pump 7 is arranged to be located in the temperature control medium in the medium storage device 12. For example, the pump 7 is arranged to be located on the first pipeline 10. For another example, the pump 7 is arranged to be located on the first pipeline 10.

[0038] In another exemplary embodiment of the present application, the above-mentioned integrated large thin-walled die casting mold temperature control system further includes: The second heating device 9 is used to heat the temperature control medium in the conveying pipeline 6 .

[0039] In the embodiment of the present application, the installation position of the second heating device 9 is not limited and can be set according to actual needs. For example, the second heating device 9 is arranged on the conveying pipeline 6. For example, the second heating device 9 is arranged in the temperature control medium in the medium storage device 12. For another example, the second heating device 9 is arranged on the first pipeline 10. For another example, the second heating device 9 is arranged on the outside of the bottom of the medium storage device 12. In order to improve the heating efficiency of the temperature control medium, a second heating device 9 arranged outside the mold body 5 can be used to heat the temperature control medium in advance, and the temperature control medium heated by the second heating device 9 is conveyed to the spacer tube 2 through the conveying pipeline 6, and then the first heating device 3 is used to heat the temperature control medium flowing through the spacer tube 2 to compensate for the heat loss caused by the conveying pipeline 6.

[0040] In another exemplary embodiment of the present application, the first heating device 3 is an electric heating device.

[0041] Accordingly, the above-mentioned integrated large thin-walled die casting mold temperature control system, such as Figure 3 As shown, a switch 13 is also included to control the opening and closing of the first heating device 3.

[0042] In the embodiment of the present application, the switch 13 is arranged on the connection line between the first heating device 3 and the power supply 15. When the switch 13 is in a closed state, the first heating device 3 is connected to the power supply 15 and can work normally; when the switch 13 is in an open state, the first heating device 3 is disconnected from the power supply 15 and stops working.

[0043] In another exemplary embodiment of the present application, the above-mentioned integrated large thin-walled die casting mold temperature control system further includes: The controller 14 is used to control the switch 13 to be turned on and off according to the medium temperature value detected in real time by the temperature detection device 4 .

[0044] In the embodiment of the present application, when the medium temperature value detected in real time by the temperature detection device 4 is not greater than the first preset temperature value, the switch 13 is controlled to be closed by the controller 14 until the medium temperature value detected in real time is greater than the first preset temperature value, so that when the medium temperature value detected in real time by the temperature detection device 4 is not greater than the first preset temperature value, the first heating device 3 is controlled to be turned on to heat the temperature control medium flowing through the spacer tube 2, so as to heat the temperature control medium to the first preset temperature value inside the mold body 5, and use the heated temperature control medium to heat the mold body 5 to the desired temperature value.

[0045] In another exemplary embodiment of the present application, the first heating device 3 adopts a spiral cylindrical heating element, and is arranged along the length direction of the spacer tube 2 and installed on the inner wall of the spacer tube 2 to ensure uniform and efficient heat transfer.

[0046] In another exemplary embodiment of the present application, the first heating device 3 is an electric heating wire or an electromagnetic induction coil.

[0047] In the embodiment of the present application, the electromagnetic induction coil is a heating element that generates heat using the principle of electromagnetic induction, and it is wound by an insulated wire. When current passes through the electromagnetic induction coil, a changing magnetic field will be generated around it. In the magnetic field generated by the electromagnetic induction coil, if the spacer tube 2 is a magnetic conductive material (such as copper, iron, nickel, etc.), eddy currents will be induced in the changing magnetic field. When the eddy current flows, heat will be generated due to the effect of resistance, thereby achieving a heating effect. The heating wire is a resistive heating element, usually made of a metal alloy with high resistivity and high melting point, such as nickel-chromium alloy, iron-chromium-aluminum alloy, etc. When the heating wire is energized, the electrical energy will be converted into thermal energy due to the effect of resistance. This thermal energy is transferred to the spacer tube 2 by heat conduction, thereby heating the temperature control medium.

[0048] In another exemplary embodiment of the present application, the heating power of the first heating device 3 is adjustable.

[0049] In the embodiment of the present application, the current of the heating wire can be adjusted to accurately control the heating power, thereby achieving accurate adjustment of the temperature of the mold body 5.

[0050] In another exemplary embodiment of the present application, the controller 14 is further configured to: According to the first preset temperature value and the medium temperature value detected in real time by the temperature detection device 4, the rotation speed of the pump 7 is adjusted to achieve accurate temperature control.

[0051] In the embodiment of the present application, the first preset temperature value ensures that the mold body 5 can reach the required temperature during the heating process to meet the requirements of melting, flowing and solidification of the material, thereby producing a product that meets the quality standards. The pump 7 uses an adjustable speed motor (such as a variable frequency motor), and the controller 14 adjusts the speed of the pump 7 through a speed controller (such as a frequency converter).

[0052] In another exemplary embodiment of the present application, the above-mentioned integrated large-scale thin-walled die-casting mold temperature control system further includes a cooling device for reducing the temperature of the temperature control medium delivered to the spacer tube 2.

[0053] In the embodiment of the present application, the temperature-controlled medium after the temperature is reduced flows in the medium channel 1 and directly contacts the mold body 5. Since the temperature of the temperature-controlled medium is higher than the temperature of the mold body 5, heat exchange occurs between the two, and the temperature-controlled medium transfers heat to the mold body 5, thereby heating the mold body 5. The main function of the cooling device is to provide cooling capacity so as to reduce the temperature of the temperature-controlled medium when necessary, which helps to prevent the temperature-controlled medium from overheating, so that the temperature of the temperature-controlled medium is kept within a set range, and ensures the molding quality and production efficiency of the product. There is no limitation on the specific structure and cooling method of the cooling device, which can be selected according to actual needs. For example, an air cooling device is used. For another example, a heat exchange device based on cooling the temperature-controlled medium is used. There is no specific limitation on the installation position of the cooling device, which can be selected according to actual needs. For example, the cooling device is set on the conveying pipeline 6. For example, the cooling device is set on the first pipeline 10. For another example, the cooling device is set on the second pipeline 11. For another example, the cooling device is set on the medium storage device 12. For another example, the heat exchange device is arranged between the temperature control medium inlet and the temperature control medium outlet of the delivery pipeline 6, so that the temperature control medium flowing out of the temperature control medium outlet is cooled by the heat exchange device and then flows into the delivery pipeline 6 from the temperature control medium inlet. When a heat exchange device based on cooling the temperature control medium is used as a cooling device, the cooling device is started, that is, the cooling temperature control medium is started to be transported to the heat exchange device, so that the cooling temperature control medium is used to exchange heat with the medium storage device 12 or the delivery pipeline 6, and the temperature of the temperature control medium in the medium storage device 12 or the delivery pipeline 6 is cooled.

[0054] In another exemplary embodiment of the present application, Figure 4 As shown, a method for controlling the temperature of a die-casting mold for an integrated large thin-walled part is provided. The method is based on the above-mentioned temperature control system for the die-casting mold for an integrated large thin-walled part, and is executed by the controller 14 of the above-mentioned temperature control system for the die-casting mold for an integrated large thin-walled part, and includes the following steps 101 to 104. Among them: Step 101, controlling the pump 7 to operate so that the temperature control medium circulates in the circulation loop.

[0055] Step 102 : acquiring the medium temperature value detected by the temperature detection device 4 in real time.

[0056] Step 103 , if the medium temperature value obtained in real time is not greater than the first preset temperature value, the first heating device 3 is controlled to start, so as to heat the temperature control medium flowing through the spacer tube 2 .

[0057] Step 104: If the medium temperature value obtained in real time is greater than the first preset temperature value, the first heating device 3 is controlled to be turned off.

[0058] In another exemplary embodiment of the present application, the above-mentioned one-piece large thin-walled part die-casting mold temperature control method further includes: Step 105, if the medium temperature value obtained in real time is not less than the second preset temperature value, control the cooling device to start and cool the temperature control medium in the circulation loop until the medium temperature value obtained in real time is greater than the first preset temperature value and less than the second preset temperature value; wherein the second preset temperature value refers to a safety temperature threshold, and the safety temperature threshold is not less than the maximum temperature value required to heat the mold body 5 to the target temperature.
