Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an aluminum alloy die-casting mold. Background Technology

[0002] Aluminum alloy die casting is a widely used manufacturing process in industrial production. It involves injecting molten aluminum alloy at high temperatures into a mold, which is then rapidly cooled and shaped to create metal parts with complex shapes and high precision. Due to its efficiency and economy, this process is widely used in the automotive, aerospace, and electronics industries.

[0003] Chinese patent document CN 221734781U discloses an aluminum alloy die-casting mold, belonging to the field of die-casting molds. It includes a fixed mold and a moving mold. The fixed mold has a cavity and is mounted on a first mounting plate. The moving mold has a core mounted on it, located above the cavity, and is mounted on a second mounting plate. However, the above technical solution still has the following drawbacks: In the prior art, after the product is die-cast, it is usually tightly fitted to the mold, making it difficult to remove directly. Furthermore, the product remains at a high temperature after forming, posing a significant safety hazard to operators who attempt to remove it.

[0004] Therefore, an aluminum alloy die-casting mold is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum alloy die-casting mold in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An aluminum alloy die-casting mold includes a base plate, a moving mold and a fixed mold arranged on the top of the base plate, a support frame and a grouting pipe fixedly connected to the right side of the fixed mold, and the bottom end of the support frame fixedly connected to the top surface of the base plate, an automatic demolding component for ejecting aluminum alloy products inside the fixed mold arranged on the left side of the top surface of the base plate, a cooling box fixedly connected to the middle of the top surface of the base plate, and the interior of the cooling box containing coolant, a receiving tray arranged below the fixed mold, a guide hole through the bottom of the receiving tray, a lifting control component for controlling the vertical movement of the receiving tray installed on the right side of the top surface of the base plate, and a cooling component arranged on the surface of the cooling box.

[0008] Furthermore, the lifting control component includes a motor, which is fixedly installed on the top surface of the base plate. A threaded rod is fixedly connected to the output end of the motor, and a connecting frame is threadedly connected to the surface of the threaded rod. The left end of the connecting frame is fixedly connected to the right side of the receiving tray, and the connecting frame is slidably connected to the support frame.

[0009] Furthermore, the cooling component includes a thermoelectric cooler, which is fixedly mounted on the front of the cooling box. A protective shell is fixedly connected to the front of the cooling box, and the thermoelectric cooler is located inside the protective shell. A cooling plate is fixedly connected to the cold end of the thermoelectric cooler, and the cooling plate is in contact with the coolant.

[0010] Furthermore, a heat sink is fixedly connected to the hot end of the semiconductor cooling chip, and a cooling fan is fixedly installed on the front side of the protective shell.

[0011] Furthermore, the automatic demolding assembly includes a mounting plate, which is fixedly connected to the top surface of the base plate. An electric push rod is fixedly mounted on the left side of the mounting plate, and the telescopic end of the electric push rod is fixedly connected to the moving mold. A guide rod is fixedly connected to the left side of the moving mold and is movably inserted into the mounting plate. An ejector rod is fixedly connected to the right side of the mounting plate and is movably inserted into the moving mold.

[0012] Furthermore, there are four guide rods, and the four guide rods are respectively located at the four corners of the back of the moving mold, and the telescopic end of the electric push rod is located at the geometric center of the left side of the moving mold.

[0013] The beneficial effects of this utility model are as follows:

[0014] After the moving mold and fixed mold are closed, molten aluminum is injected into the cavity under pressure through the injection pipe. After a period of cooling and solidification, the automatic demolding component moves the moving mold to the left and pushes out the aluminum alloy product inside the moving mold, allowing it to fall into the receiving tray. Then, the lifting control component moves the receiving tray downwards, allowing the tray and the aluminum alloy product to enter the cooling box, where the aluminum alloy product is submerged in the coolant. The coolant flow is facilitated by the guide holes, and the coolant absorbs the heat from the aluminum alloy product, cooling it down. After cooling, the receiving tray is raised by the lifting control component, allowing the product to detach from the coolant and be removed. The cooling component further cools the coolant inside the cooling box, maintaining a low and stable temperature. This invention achieves the effect of automatic demolding of die-cast aluminum alloy products and allows for rapid cooling again, making the removal of aluminum alloy products more convenient and safer.

[0024] like Figures 1 to 3As shown, an aluminum alloy die-casting mold includes a base plate 1, a moving mold 2 and a fixed mold 3 are arranged above the base plate 1, a support frame 4 and a grouting pipe 10 are fixedly connected to the right side of the fixed mold 3, and the bottom end of the support frame 4 is fixedly connected to the top surface of the base plate 1. An automatic demolding component 9 for ejecting the aluminum alloy product inside the fixed mold 3 is arranged on the left side of the top surface of the base plate 1. A cooling box 7 is fixedly connected to the middle of the top surface of the base plate 1, and the interior of the cooling box 7 is filled with coolant. A receiving tray 5 is arranged below the fixed mold 3, and a guide hole is opened through the bottom of the receiving tray 5. A lifting control component 6 for controlling the vertical movement of the receiving tray 5 is installed on the right side of the top surface of the base plate 1. A cooling component 8 is arranged on the surface of the cooling box 7. More specifically, after the moving mold 2 and the fixed mold 3 are closed, molten aluminum can be injected into the cavity under pressure through the injection pipe 10. After a period of cooling and forming, the automatic demolding component 9 can be used to control the moving mold 2 to move to the left and push out the aluminum alloy product inside the moving mold 2, so that the aluminum alloy product falls into the receiving tray 5. Then, the lifting control component 6 is used to control the receiving tray 5 to move downward, so that the receiving tray 5 and the aluminum alloy product enter the cooling box 7, so that the aluminum alloy product is submerged in the coolant. By setting guide holes, the coolant can be facilitated to flow. Then, the coolant absorbs the heat of the aluminum alloy product and cools it down. After cooling is completed, the lifting control component 6 can be used to control the receiving tray 5 to rise, so that the product is removed from the coolant. Then the aluminum alloy product can be picked up. The cooling component 8 can be used to cool the coolant inside the cooling box 7 and keep it at a low and stable temperature.

[0025] The lifting control assembly 6 includes a motor 601, which is fixedly mounted on the top surface of the base plate 1. A threaded rod 602 is fixedly connected to the output end of the motor 601. A connecting frame 603 is threadedly connected to the surface of the threaded rod 602, and the left end of the connecting frame 603 is fixedly connected to the right side of the receiving tray 5. The connecting frame 603 is slidably connected to the support frame 4. It should be noted that the operation of the motor 601 drives the threaded rod 602 to rotate, and under the action of the thread, the connecting frame 603 can slide along the surface of the support frame 4, thereby controlling the vertical movement of the receiving tray 5.

[0026] The cooling component 8 includes a thermoelectric cooler 801, which is fixedly mounted on the front of the cooling box 7. A protective shell 802 is fixedly connected to the front of the cooling box 7, and the thermoelectric cooler 801 is located inside the protective shell 802. A cooling conductor 803 is fixedly connected to the cold end of the thermoelectric cooler 801, and the cooling conductor 803 is in contact with the coolant. More specifically, by operating the thermoelectric cooler 801, cooling is performed using its cold end, and the coolant is cooled by contact with the coolant through the cooling conductor 803, thus maintaining the coolant at a low temperature and ensuring the cooling effect on the aluminum alloy product.

[0027] A heat sink 804 is fixedly connected to the hot end of the thermoelectric cooler 801, and a cooling fan 805 is fixedly installed on the front of the protective shell 802. It should be noted that by setting the heat sink 804, the heat dissipation of the hot end of the thermoelectric cooler 801 can be accelerated, and by operating the cooling fan 805, the airflow is further accelerated, which helps the thermoelectric cooler 801 dissipate heat.

[0028] The automatic demolding assembly 9 includes a mounting plate 901, which is fixedly connected to the top surface of the base plate 1. An electric push rod 902 is fixedly mounted on the left side of the mounting plate 901, and the telescopic end of the electric push rod 902 is fixedly connected to the moving mold 2. A guide rod 903 is fixedly connected to the left side of the moving mold 2 and is movably inserted into the mounting plate 901. An ejector rod 904 is fixedly connected to the right side of the mounting plate 901 and is movably inserted into the moving mold 2. More specifically, the electric push rod 902 moves the moving mold 2 to the left. The ejector rod 904 slides on the surface of the mounting plate 901, providing stable support for the moving mold 2. Under the action of the ejector rod 904, the product inside the moving mold 2 is ejected from inside the moving mold 2 and falls into the receiving tray 5.

[0029] There are four guide rods 903, which are respectively located at the four corners of the back of the moving mold 2. The telescopic end of the electric push rod 902 is located at the geometric center of the left side of the moving mold 2. It should be noted that by setting four guide rods 903 and placing the telescopic end of the electric push rod 902 at the geometric center of the left side of the moving mold 2, the pulling of the moving mold 2 is more stable.

[0030] In summary: After the moving mold 2 and the fixed mold 3 are closed, molten aluminum can be injected into the cavity under pressure through the injection pipe 10. After a period of cooling and forming, the automatic demolding component 9 can be used to control the moving mold 2 to move to the left and push out the aluminum alloy product inside the moving mold 2, allowing the aluminum alloy product to fall into the receiving tray 5. Then, the lifting control component 6 is used to control the receiving tray 5 to move downward, allowing the receiving tray 5 and the aluminum alloy product to enter the cooling box 7, where the aluminum alloy product is submerged in the coolant. The coolant flow is facilitated by the guide holes, and the coolant absorbs the heat of the aluminum alloy product to cool it down. After cooling, the receiving tray 5 can be raised by the lifting control component 6, allowing the product to be removed from the coolant. The aluminum alloy product can then be picked up. The cooling component 8 can cool the coolant inside the cooling box 7 to keep it at a low and stable temperature. In use, this utility model achieves the effect of automatic demolding of die-cast aluminum alloy products and can also quickly cool the product again, making it more convenient and safer to pick up the aluminum alloy products.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
