[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] like Figure 1 、 2As shown in Figure 4, the present application provides a die-casting mold demoulding structure, including a base 1, an air bag 4 and a water tank 5. The bottom of the base 1 is open, and a vacuum pump 2 is installed on the base 1. The vacuum pump 2 can be fixed to the base 1 by bolts. The output end of the vacuum pump 2 is connected to the inner cavity of the base 1. The bottom end of the base 1 is set as an annular structure, and an annular groove 3 is opened at the edge of the bottom end of the base 1. A circulation component 8 is set on the outside of the base 1. The air bag 4 is set as an annular structure, and the air bag 4 is installed in the inner cavity of the annular groove 3. The outer end of the base 1 is equipped with an air pump. The air pump can be fixed to the base 1 by bolts, the output end of the air pump is connected to the airbag 4, the water tank 5 is installed at the outer end of the base 1, the water tank 5 can be fixed to the base 1 by bolts, and a first water pump 6 is installed on the water tank 5, the first water pump 6 can be fixed to the water tank 5 by bolts, a water injection pipe 7 is installed at the outer end of the base 1, the water injection pipe 7 can be fixed to the base 1 by welding, one end of the water injection pipe 7 extends to the inside of the annular groove 3, and the other end of the water injection pipe 7 is connected to the inner cavity of the water tank 5 through the first water pump 6.

[0027] In the process of manufacturing compact motors, commonly used manufacturing methods include injection molding, machining, casting, forging, etc. Among them, during the die-casting process of parts, the formed workpiece needs to be demolded. Some existing demolding devices use suction cups to demold the workpiece, which has a wide range of applications. However, the die-cast workpiece is often in a high-temperature state, and the part where the suction cup contacts the workpiece is made of flexible material. Long-term contact with high temperature can easily cause it to age, thereby reducing the service life of the suction cup and damaging the sealing of the suction cup, resulting in demolding failure. Waiting for the workpiece to cool will seriously reduce processing efficiency.

[0028] In this solution, the top of the base 1 can be used for connection to a robotic arm. The robotic arm is a multi-joint mechanical device that is widely used in various application fields, including manufacturing, healthcare, logistics and warehousing. It has actuators, sensors and control systems. The robotic arm can accurately control the movement trajectory of the base 1 so that it can accurately fall on the workpiece to be demolded, and after the workpiece is adsorbed, it can drive the workpiece for demolding.

[0029] In this solution, after the bottom end of the base 1 contacts the surface of the workpiece, the user can start the air pump to expand the airbag 4, and the airbag 4 is squeezed out from the annular groove 3 and contacts the surface of the workpiece tightly. The material of the airbag 4 can be rubber. The airbag 4 can replace the traditional suction cup to form a closed space inside the base 1. Then, the user can start the vacuum pump 2 to extract the air inside the base 1, so that a negative pressure is formed inside, thereby achieving adsorption of the workpiece. However, when demolding the workpiece, since the workpiece is at a high temperature, it is difficult to directly let the airbag 4 contact the workpiece. Contact will cause damage to the airbag 4, so the user can start the first water pump 6 before starting the air pump to control the expansion of the airbag 4. The interior of the water tank 5 is filled with cooling water. The first water pump 6 introduces the cooling water into the water injection pipe 7 and injects it into the inner cavity of the annular groove 3 through the water injection pipe 7. The cooling water will fill the inner cavity of the annular groove 3 and quickly absorb the heat at the contact position with the workpiece, and quickly cool down the position of the workpiece that is about to contact the airbag 4, so that when the airbag 4 contacts the workpiece, it will not form an excessively high temperature, which effectively protects the airbag 4.

[0030] like Figure 2 As shown, the circulation component 8 includes a water suction pipe 81 and a cooler 83. The cooler 83 is installed at the outer end of the base 1. The cooler 83 can be fixed to the base 1 by bolts, and a second water pump 82 is installed at the outer end of the cooler 83. The second water pump 82 can be fixed to the cooler 83 by bolts. The water suction pipe 81 is installed at the outer end of the base 1. The water suction pipe 81 can be fixed to the base 1 by welding, and one end of the water suction pipe 81 extends to the inner cavity of the annular groove 3. The other end of the water suction pipe 81 is connected to the inner cavity of the cooler 83 through the second water pump 82. A circulation pipe 84 is installed at the outer end of the cooler 83. The circulation pipe 84 can be fixed to the cooler 83 by welding. The two ends of the circulation pipe 84 are respectively connected to the inner cavity of the cooler 83 and the water tank 5. The water suction pipe 81 is arranged in the opposite direction of the water injection pipe 7.

[0031] In this solution, while the water injection pipe 7 injects cooling water into the interior of the annular groove 3, the user can start the second water pump 82. The second water pump 82 can pump out the water in the annular groove 3 through the pumping pipe 81 and introduce it into the cooler 83. The cooler 83 is usually used to quickly cool hot water or other fluids. Its working principle is based on heat exchange and convection heat transfer, which is the existing technology. The water cooled by the cooler 83 returns to the circulation pipe 84 through the circulation pipe 84, thereby realizing the cooling water circulation, so that the cooling water continuously flows in the annular groove 3 in the form of flow, thereby improving the cooling speed. The pumping pipe 81 is set in the opposite direction of the water injection pipe 7, which can ensure that the cooling water flows completely through the interior of the annular groove 3, thereby improving the uniformity of heat dissipation.

[0032] like Figure 3As shown, the bottom of the water injection pipe 7 is arranged around the outer end of the base 1, and the water injection pipe 7 abuts against the outer end of the base 1.

[0033] In this solution, when the base 1 abuts against the workpiece, part of the heat of the workpiece will also be transferred to the base 1. The water injection pipe 7 is arranged around the base 1, so that the cooling water can absorb the surface temperature of the base 1 during the flow in the water injection pipe 7, further improving the heat dissipation effect. The material of the water injection pipe 7 can be set to copper, which has excellent thermal conductivity.

[0034] like Figure 3-4 As shown, a pair of coaxially arranged heat-conducting blocks 9 are installed at the bottom end of the base 1. The heat-conducting blocks 9 can be fixed to the base 1 by welding. The pair of heat-conducting blocks 9 are respectively arranged on the inner and outer sides of the annular groove 3.

[0035] In this solution, the material of the heat-conducting block 9 can be set to copper, which is in direct contact with the workpiece and can quickly conduct the heat from the workpiece surface. At the same time, the cooling water inside the annular groove 3 is also in direct contact with the heat-conducting block 9, thereby accelerating the conduction of heat from the workpiece surface to the cooling water and improving the cooling speed.

[0036] A filter screen 10 is installed on the inner wall of the water extraction pipe 81 extending to one end of the inner cavity of the base 1 . The filter screen 10 can be fixed to the water extraction pipe 81 by means of bolts.

[0037] In this solution, considering the presence of fine impurities on the surface of the workpiece, in order to prevent the impurities from entering the pumping pipe 81 with the cooling water and causing blockage of the inner cavity of the pumping pipe 81, a filter 10 is installed at the inner end of the pumping pipe 81, which can effectively intercept the impurities and ensure the stable circulation of the cooling water.

[0038] Working principle:

[0039] During use, the user manipulates the robotic arm to make the base 1 contact the surface of the workpiece to be demoulded, and then starts the first water pump 6. The first water pump 6 guides the cooling water in the water tank 5 into the water injection pipe 7, and injects it into the inner cavity of the annular groove 3 through the water injection pipe 7. The cooling water will fill the inner cavity of the annular groove 3 and quickly absorb the heat at the contact position with the workpiece, and quickly cool the position where the workpiece will contact the airbag 4. The user also starts the second water pump 82. The second water pump 82 draws the cooling water out of the annular groove 3 through the pumping pipe 81 and guides it into the cooler 83. After cooling by the cooler 83, the cooling water The water returns to the circulation pipe 84 through the circulation pipe 84, thereby realizing the cooling water circulation, so that the cooling water continuously flows in the annular groove 3 in the form of flow. After cooling for a period of time, the temperature of the workpiece surface around the annular groove 3 is reduced. At this time, the user starts the air pump to cause the airbag 4 to expand. The airbag 4 is squeezed out from the annular groove 3 and tightly abuts the surface of the workpiece, forming a closed space inside the base 1. Then the user starts the vacuum pump 2 to extract the air inside the base 1, so that negative pressure is formed inside, thereby achieving adsorption of the workpiece and driving the workpiece to be demolded through the robotic arm.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
