Description

Technical Field

[0001] The utility model relates to the technical field of tire mold casting, and more particularly to a metal casting mold which is easy to demould. Background Art

[0002] With the continuous increase in global car ownership and the continued development of the tire industry, the demand for tire molds is also growing. This is particularly true in emerging and developing markets, where the rapid development of the automotive industry has driven a booming tire mold market. A search revealed a Chinese patent with authorization publication number CN217393660U, which discloses a metal casting mold that facilitates demolding. The mold is equipped with a cooling pipe. When the mold needs to be cooled, cold water is delivered to the cooling pipe via an external water delivery device. Because the cooling pipe winds its way through the lower mold, it absorbs heat from the molten metal through the lower mold, accelerating the cooling of the casting and improving the casting efficiency of the device.

[0003] However, in actual use, although a cooling mechanism is loaded to reduce the temperature and improve the efficiency of the casting molding of the device, due to the certain weight of the casting, when removing the mold parts, workers need to use tools to pry the casting, which not only easily damages the casting and the mold, but also slows the operation process.

[0012] Technical effects and advantages of this utility model:

[0013] 1. By setting up a clamping and lifting mechanism and starting the stepper motor, the stepper motor drives the screw to rotate. When the screw rotates, the moving block moves up and down with the rotation of the screw. When the moving block moves to the specified position, the protrusion is clamped inside the casting by pulling the pull plate. Then, the stepper motor is started again to remove the casting from the lower mold. The operation is simple and can effectively avoid scratches or collisions on the casting surface (especially the complex pattern part on the outside);

[0014] 2. By setting up an auxiliary mechanism and starting the cylinder, the output end of the cylinder drives the upper mold to move upward. During the period of combining the upper and lower molds, the upper mold can be lowered slowly and steadily so that it can be accurately docked with the lower mold, realizing precise control of the position of the upper mold and effectively improving the quality of the casting.

Then the stepper motor 9 is started, and the stepper motor 9 drives the screw rod 8 to rotate. When the screw rod 8 rotates, the moving block 10 moves up and down with the rotation of the screw rod 8. When the moving block 10 moves to the specified position, the protrusion 14 is stuck in the casting by pulling the pull plate 12. Then the stepper motor 9 is started again, and the stepper motor 9 drives the screw rod 8 to rotate. When the screw rod 8 rotates, the moving block 10 moves with the rotation of the screw rod 8 to lift the casting. The electric slide rail 2 drives the sliding plate 3 back to its original position. The auxiliary mechanism drops the upper mold 5 to the top of the lower mold 4, and it can be poured again. Then the stepper motor 9 drives the screw rod 8 to rotate again, and the moving block 10 moves with the rotation of the screw rod 8 to place the casting on the base 1, and move the sliding plate 3 to remove the protrusion 14 from the inside of the casting. After that, the staff can remove the casting.

[0025] In a specific embodiment, as shown in the attached Figure 1 、 3 As shown in Figure 4, a plurality of sockets 15 are provided at the top of the lower mold 4, a plurality of insertion rods 16 are fixedly connected to the bottom of the upper mold 5, the insertion rods 16 are slidably connected to the sockets 15, and a liquid inlet 17 is fixedly connected to the top of the upper mold 5, so that when the upper mold 5 and the lower mold 4 are combined, there is better stability and precision.

[0026] Specifically, in this structure, when the upper mold 5 is removed from or placed on the top of the lower mold 4, the insertion rod 16 can be accurately inserted into the corresponding slot to ensure that the positions of the upper mold 5 and the lower mold 4 in the horizontal and vertical directions are accurate.

[0030] Specifically, in this structure, by starting the cylinder 19, the output end of the cylinder 19 drives the upper mold 5 to move.

[0031] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the stepper motor 9 is fixedly mounted on the top of the support plate 6, the output end of the stepper motor 9 passes through the top of the support plate 6, and the output end of the stepper motor 9 is fixedly connected to the screw rod 8, so that the stepper motor 9 drives the screw rod 8 to rotate, so that the moving block 10 moves.

[0032] Specifically, in this structure, the output end of the stepping motor 9 drives the screw rod 8 to rotate, and the moving block 10 moves up and down by causing the screw rod 8 to rotate forward and reverse.

[0033] In a specific embodiment, as shown in the attached Figure 2 、 5 As shown, a fixed plate 20 is fixedly connected between the two moving blocks 10. The fixed plate 20 is arranged on the top of the pulling plate 12 to improve the stability of the pulling plate 12 when lifting the casting.

[0034] Specifically, in this structure, a fixed plate 20 is fixed between the two moving blocks 10, so that the pulling plate 12 has a better supporting effect when lifting the casting.

[0035] The working principle of the utility model is as follows: the solution is poured into the mold through the liquid inlet 17. After cooling, the cylinder 19 is started, and the output end of the cylinder 19 drives the upper mold 5 to move upward, and then the electric slide 2 is started, and the electric slide 2 drives the sliding plate 3 to be sent between the two support plates 6. The stepper motor 9 is started, and the stepper motor 9 drives the screw rod 8 to rotate. When the screw rod 8 rotates, the moving block 10 moves up and down with the rotation of the screw rod 8.
