Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of die casting technology, and more particularly to a die casting material temperature control system and a quantitative feeder control device. Background Art
[0002] In normal production, the automatic die-casting operation is started by pressing the start button on the die-casting machine, wherein the die-casting material (e.g., molten metal, such as molten aluminum) of the die-casting machine is provided by a holding furnace, and the molten aluminum is quantitatively extracted from the holding furnace by a quantitative feeder (e.g., a soup feeder), and poured into the mold (e.g., a melting cup) of the die-casting machine for die-casting. During production, the operator will not check the temperature of the die-casting material in the holding furnace in real time, but when the temperature of the die-casting material in the holding furnace does not reach the predetermined temperature, such as 700°C, the final die-casting (e.g., a rotor) will have an insufficient rotor filling rate due to the low temperature of the die-casting material, resulting in the scrapping of the final die-casting, thereby resulting in relatively low productivity. Utility Model Content
[0003] 1. Technical issues
[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a die-casting material temperature control system and a quantitative feeder control device, which solves the problem that traditional die-casting equipment continues to produce castings when the temperature is insufficient, and avoids the production of defective products when the temperature conditions do not meet the standards.
[0005] (II) Technical solution
[0006] To achieve the above objectives, the present disclosure is implemented through the following technical solutions:
[0007] According to one aspect of an embodiment of the present application, a die-casting material temperature control system is provided, the die-casting material temperature control system includes a die-casting machine, a quantitative feeder, and a holding furnace, the holding furnace contains molten die-casting material and keeps the temperature of the molten die-casting material at a predetermined temperature, the quantitative feeder transfers the molten die-casting material in the holding furnace to a mold of the die-casting machine to die-cast into a final die-casting, the die-casting material temperature control system also includes: a holding furnace temperature monitoring device, the holding furnace temperature monitoring device includes: a temperature sensor, which is arranged in the holding furnace to detect the temperature of the molten die-casting material; and a holding furnace temperature control box, which is arranged outside the holding furnace and connected to the temperature sensor to receive a temperature detection signal indicating the detected temperature from the temperature sensor; and a quantitative feeder control device, which is connected to the holding furnace temperature control box to receive the temperature detection signal from the holding furnace temperature control box, wherein the quantitative feeder control device is connected to the quantitative feeder and transmits a feeder deactivation control signal to the quantitative feeder in response to the detected temperature being lower than the predetermined temperature, and the quantitative feeder stops working in response to receiving the feeder deactivation control signal.
[0008] In this way, by arranging a temperature control box for the insulation furnace outside the insulation furnace, the temperature information of the molten die-casting material in the insulation furnace can be transmitted to the quantitative feeder, so that the quantitative feeder can learn the temperature of the molten die-casting material in the insulation furnace, and determine whether to act according to the temperature of the molten die-casting material. For example, when the temperature of the molten die-casting material (for example, aluminum liquid) in the insulation furnace does not reach the predetermined temperature (i.e., the set value), the quantitative feeder will no longer act, thereby no longer quantitatively extracting the molten die-casting material from the insulation furnace, and correspondingly, the molten die-casting material will not be injected into the mold of the die-casting machine. Since there is no predetermined amount of molten die-casting material in the die-casting machine, the die-casting machine will not perform die-casting, thereby solving the problem of traditional die-casting equipment continuing to produce castings when the temperature is insufficient, and avoiding the production of defective products when the temperature conditions are not up to standard.
[0009] According to an exemplary embodiment of the present application, a quantitative feeder includes: a multi-axis robotic arm; a scoop, which is installed at the free end of the multi-axis robotic arm and driven by the multi-axis robotic arm to move back and forth between a holding furnace and a die-casting machine to transfer the molten die-casting material in the holding furnace to a mold of the die-casting machine; and a driving device, which drives the multi-axis robotic arm to move to drive the scoop to move, wherein a quantitative feeder control device transmits a feeder deactivation control signal to the driving device to stop the driving operation of the driving device.
[0010] In this way, the feeding process can be automated, manual monitoring and intervention can be reduced, labor costs can be reduced, and the feeding can be quickly cut off, thereby avoiding supplying molten die-casting materials with insufficient temperature to the die-casting machine, avoiding the waste of molten die-casting materials and the scrapping of die-casting parts.
[0011] According to an exemplary embodiment of the present application, the die-casting material temperature control system also includes a die-casting machine control device, which is arranged outside the die-casting machine and connected to the die-casting machine. The die-casting machine control device is also connected to the insulation furnace temperature control box to receive a temperature detection signal from the insulation furnace temperature control box and transmit a die-casting machine deactivation control signal to the die-casting machine in response to the detected temperature being lower than a predetermined temperature. The die-casting machine stops working in response to receiving the die-casting machine deactivation control signal.
[0012] In this way, the temperature information of the molten die-casting material in the holding furnace can be conveyed to the die-casting machine, so that the die-casting machine can learn the temperature of the molten die-casting material in the holding furnace, and determine whether to act according to the temperature of the molten die-casting material. For example, when the temperature of the molten die-casting material (for example, molten aluminum) in the holding furnace does not reach a predetermined temperature (i.e., a set value), the die-casting machine will no longer perform die-casting, thereby solving the problem of traditional die-casting equipment continuing to produce castings when the temperature is insufficient, and avoiding the production of defective products when temperature conditions do not meet the standards.
[0013] According to an exemplary embodiment of the present application, the die-casting machine also includes: a molten die-casting material amount detector, which is arranged on the mold and detects the amount of molten die-casting material in the mold of the die-casting machine; wherein the molten die-casting material amount detector is connected to the die-casting machine control device to transmit a material amount detection signal indicating the detected amount of molten die-casting material to the die-casting machine control device, and the die-casting machine control device transmits a die-casting machine deactivation control signal to the die-casting machine in response to the detected amount of molten die-casting material being less than a set amount value.
[0014] In this way, it is possible to cooperate with the operation of the feeder to solve the problem of traditional die-casting equipment continuing to produce castings when the temperature is insufficient, and avoid the production of defective products when the temperature conditions are not up to standard. At the same time, it can avoid the situation where some parts of the mold may not be completely filled with the molten die-casting material due to insufficient amount of molten die-casting material in the die-casting machine, resulting in defects such as voids or shrinkage holes inside the casting and depressions or cracks in the casting, thereby improving the productivity of the casting.
[0015] According to an exemplary embodiment of the present application, the temperature control box of the insulation furnace also includes a temperature display meter, which displays the detected temperature for the user to view.
[0016] In this manner, the temperature of the holding furnace can be monitored in real time with a simple structure.
[0017] According to an exemplary embodiment of the present application, the molten die casting material includes molten aluminum liquid.
[0018] According to an exemplary embodiment of the present application, the temperature control box of the insulation furnace further includes an alarm, which generates an alarm in response to the detected temperature being lower than a predetermined temperature.
[0019] In this way, an alarm can be generated when the temperature is too low, thereby warning the operator in advance that the metal temperature is dropping and prompting the operator to promptly check and maintain the holding furnace to quickly resume operation of the holding furnace.
[0020] According to another exemplary embodiment of the present application, a quantitative feeder control device is provided, which is used in a die-casting material temperature control system. The die-casting material temperature control system includes a die-casting machine, a quantitative feeder, and a holding furnace. The holding furnace contains molten die-casting material and keeps the temperature of the molten die-casting material at a predetermined temperature. The quantitative feeder transfers the molten die-casting material in the holding furnace to a mold of the die-casting machine to die-cast into a final die-casting. The die-casting material temperature control system also includes: a holding furnace temperature monitoring device, the holding furnace temperature monitoring device includes: a temperature sensor, which is arranged in the holding furnace to detect the temperature of the molten die-casting material; and a holding furnace temperature control box, which is arranged outside the holding furnace and connected to the temperature sensor to receive a temperature detection signal indicating the detected temperature from the temperature sensor; the quantitative feeder control device is connected to the holding furnace temperature control box to receive the temperature detection signal from the holding furnace temperature control box, wherein the quantitative feeder control device is connected to the quantitative feeder and transmits a feeder deactivation control signal to the quantitative feeder in response to the detected temperature being lower than the predetermined temperature, and the quantitative feeder stops working in response to receiving the feeder deactivation control signal.
[0021] (III) Technical Effect
[0022] In an embodiment of the present application, a die-casting material temperature control system and a quantitative feeder control device are provided, wherein, by arranging a temperature control box for the insulation furnace outside the insulation furnace, the temperature information of the molten die-casting material in the insulation furnace can be transmitted to the quantitative feeder and the die-casting machine, so that the quantitative feeder and the die-casting machine can learn the temperature of the molten die-casting material in the insulation furnace, and determine whether to act according to the temperature of the molten die-casting material. For example, when the temperature of the molten die-casting material (for example, aluminum liquid) in the insulation furnace does not reach a predetermined temperature (i.e., a set value), the quantitative feeder will no longer act, thereby no longer quantitatively extracting the molten die-casting material from the insulation furnace, and correspondingly, the molten die-casting material will not be poured into the mold of the die-casting machine. Since there is no predetermined amount of molten die-casting material in the die-casting machine, the die-casting machine will not perform a die-casting action, thereby solving the problem that traditional die-casting equipment continues to produce castings when the temperature is insufficient, and avoids the production of defective products when the temperature conditions are not up to standard.

[0037] As discussed in the previous background art, conventional die casting equipment continues to produce castings when the temperature is insufficient, thereby resulting in the production of defective products when the temperature conditions do not meet the standards.
[0038] To this end, the concept of the present disclosure is to provide a temperature control box for the insulation furnace outside the insulation furnace, so that the temperature information of the molten die-casting material in the insulation furnace can be transmitted to the quantitative feeder and the die-casting machine, so that the quantitative feeder and the die-casting machine can be aware of the temperature of the molten die-casting material in the insulation furnace, and determine whether to act according to the temperature of the molten die-casting material, thereby solving the problem of traditional die-casting equipment continuing to produce castings when the temperature is insufficient, and avoiding the production of defective products when the temperature conditions are not up to standard.
[0039] Figure 1 1 is a schematic diagram of a die-casting material temperature control system according to an embodiment of the present application. The die-casting material temperature control system 100 includes a die-casting machine 10, a quantitative feeder 20, and a holding furnace 30. The holding furnace 30 contains molten die-casting material and keeps the temperature of the molten die-casting material at a predetermined temperature, for example, 700° C. The quantitative feeder 20 transfers the molten die-casting material in the holding furnace 30 to the mold 11 of the die-casting machine 10 to die-cast into a final die-casting.

The temperature of the molten die-casting material in the insulation furnace 30 can be detected by the temperature sensor 31 and displayed by the temperature display table 33 set on the insulation furnace temperature control box 32 for the user to view, so that the user can determine whether it is necessary to start the heater to heat the molten die-casting material in the insulation furnace 30.

[0047] The die casting material temperature control system 100 may further include a die casting machine control device 12 , which is disposed outside the die casting machine 10 and connected to the die casting machine 10 .
[0048] Specifically, the die casting machine control device 12 can be connected to the molten die casting material quantity detector to receive a material quantity detection signal indicating the detected molten die casting material quantity from the molten die casting material quantity detector, and the die casting machine control device 12 transmits a die casting machine deactivation control signal to the die casting machine 10 in response to the detected molten die casting material quantity being less than a set quantity value, thereby stopping the die casting machine 10 from working.
[0049] Alternatively or additionally, the die casting machine control device 12 can also be connected to the holding furnace temperature control box 32 to receive a temperature detection signal from the holding furnace temperature control box 32 and determine based on the received temperature detection signal that the detected temperature is lower than a predetermined temperature and transmit a die casting machine deactivation control signal to the die casting machine 10, and the die casting machine 10 stops working in response to receiving the die casting machine deactivation control signal.
