Description

Technical Field

[0001] The utility model relates to the technical field of die casting production, and more specifically to a demoulding device for die casting production. Background Art

[0002] Die casting is a metal casting process, which is mainly used to produce metal parts with complex shapes and good dimensional accuracy. During the die casting process, molten metal is quickly injected into a precision mold under high pressure, and then cooled and solidified to form the required parts. The die casting process has the advantages of high production efficiency, high material utilization rate, and good part surface quality. It is widely used in the automotive, electronics, aerospace and other industries.

[0003] After die casting is completed, a related demoulding device is generally required to remove the workpiece. In the prior art, a Chinese patent publication number CN218283687U discloses a demoulding structure for die casting production, including a lower die seat and an upper die seat, an upper clamping plate is arranged on the lower side of the upper die seat, and a core is fixed at the center of the lower surface of the upper clamping plate, and guide pillars are arranged near the four corners of the upper clamping plate, a fixed template is fixedly installed on the upper surface of the lower die seat near the left side, and a movable template that can be adjusted to move left and right is arranged on the right side of the fixed template, a blowing mechanism for blowing the workpiece off is arranged near the front side of the upper surface of the lower die seat, and a plurality of evenly arranged pads are arranged on the lower side of the lower die seat, and the resistance of the mold to the die casting workpiece is reduced by controlling the movable template to move to the right side and separate from the fixed template. At this time, the die casting can be easily ejected by the ejecting mechanism, and the die casting ejected by the provided blowing mechanism is blown, without the need for manual picking, so that the demoulding of the die casting is more convenient.

[0004] The above-mentioned prior art adopts an ejection structure for demolding. Under this structure, a movable "ejector pin" needs to be installed in the mold. In this way, a gap will be formed between the contact surface of the ejector pin and the mold. These gaps will eventually form burrs on the surface of the workpiece, thereby causing the surface of the workpiece to be rough. Generally speaking, it still has certain defects in use.

The mold clamping assembly and the blanking assembly are both installed on the support 1. The mold is closed by the mold clamping assembly, and the workpiece in the mold is taken out by the blanking assembly. The power assembly is installed between the mold clamping assembly and the blanking assembly, and the mold clamping assembly drives the blanking assembly to operate through the power assembly.

[0024] The mold closing assembly includes a frame 2 and a hydraulic cylinder 3. The frame 2 is fixedly mounted on a support 1. The hydraulic cylinder 3 is fixedly mounted on the frame 2. The fixed part of the mold is mounted on the support 1. The movable part of the mold is mounted on the movable end of the hydraulic cylinder 3. The movable part of the mold can be closed with the fixed part of the mold under the drive of the hydraulic cylinder 3. In this way, the mold can be driven to close by extending the movable end of the hydraulic cylinder 3.

[0025] The material unloading assembly includes a clamp 4, a driving disk 5 and a connecting rod 6. The driving disk 5 is rotatably installed on the support 1, and the driving disk 5 can move along the moving direction of the movable part of the mold clamping assembly, that is, along the moving direction of the movable end of the hydraulic cylinder 3. The connecting rod 6 is fixedly installed on the surface of the driving disk 5, and the clamp 4 is installed at the end of the connecting rod 6 away from the driving disk 5. At the same time, the clamp 4 can be extended into the molding cavity of the mold. In this way, it is only necessary to rotate the driving disk 5 and drive the clamp 4 to the top of the mold through the connecting rod 6, and then follow the movement of the hydraulic cylinder 3 to enter the molding cavity of the mold to clamp the workpiece, and then reverse the above steps to complete the material unloading.

[0026] It should be noted that in the present application, the clamp 4 adopts different models for different workpieces, and is not a single style clamp 4 of a fixed model. Since it is a prior art, the present application does not change it, so its structure will not be repeated.

[0027] There are several connecting rods 6, which are evenly distributed on the surface of the driving disk 5 in a circumferential manner. In this way, it can have multiple clamping functions, thereby facilitating continuous operation.

[0028] The power assembly includes a first rack 7, a second rack 8, a gear 9 and a protection box 10. The protection box 10 is fixedly installed in the middle of the frame 2. The first rack 7 and the second rack 8 are both slidably installed in the protection box 10. The gear 9 is rotatably installed in the protection box 10, and the gear 9 is meshed with the first rack 7 and the second rack 8 at the same time. At the same time, the tooth grooves of the first rack 7 and the second rack 8 are arranged relatively to each other. A connecting frame 15 is fixedly installed on the side of the first rack 7. The end of the connecting frame 15 away from the first rack 7 is fixedly connected to the movable part of the clamping assembly, that is, it is fixed to the movable end of the hydraulic cylinder 3. The top end of the rotating shaft of the driving disk 5 extends into the protection box 10 and is rotatably inserted in the second rack 8. In this way, as long as the movable end of the hydraulic cylinder 3 is extended, the first rack 7 will be driven to move downward through the connecting frame 15, the first rack 7 will drive the gear 9 to rotate, and the gear 9 will drive the second rack 8 to move upward, thereby driving the driving disk 5 to move upward.

[0029] The rotating shaft of the driving disk 5 can only rotate inside the second rack 8, and the rotating shaft of the driving disk 5 can move synchronously with the second rack 8, so that it can be ensured that the driving disk 5 can only rotate and move along its axial direction, thereby ensuring the stability of demoulding.

[0030] The power assembly also includes a motor 11, which is fixedly mounted on the lower surface of the support 1. A transmission assembly is connected between the output shaft of the motor 11 and the rotating shaft of the driving disk 5, thereby being able to drive the driving disk 5 to rotate.

[0032] A slide groove 13 is formed on the surface of the protection box 10 , and a slider 14 is slidably installed in the slide groove 13 . The slider 14 is fixedly connected to the side surface of the second rack 8 , so that the sliding stability of the second rack 8 can be effectively enhanced.

[0033] Therefore, the complete usage process is, first start the hydraulic cylinder 3 and make its movable end extend a distance, so that the hydraulic cylinder 3 will drive the first rack 7 to move down through the connecting frame 15, the first rack 7 will drive the gear 9 to rotate, the gear 9 will drive the second rack 8 to move up, thereby driving the driving plate 5 to move up, then, start the motor 11, so that the motor 11 drives the transmission rod 12 to rotate, and then drives the driving plate 5 to rotate, so that the connecting rod 6 rotates through the mold, at this time, the movable end of the hydraulic cylinder 3 can continue to be driven downward to close the mold for die casting, after the die casting is completed, drive the hydraulic cylinder 3 to move up a distance, thereby driving the driving plate 5 to move down, so that the driving plate 5 moves to the bottom of the movable part of the mold, and then drives the driving plate 5 to rotate through the motor 11, thereby driving the connecting rod 6 to rotate, so that the clamp 4 is above the molding cavity of the fixed part of the mold, and then continue to drive the movable end of the hydraulic cylinder 3 to contract, so that the clamp 4 moves down into the molding cavity and clamps the workpiece, and then reverses the above steps to take out the molded die casting.

[0034] In summary, during the entire use process, the blanking component is used to directly take the workpiece out of the molding cavity of the mold. In comparison, it is no longer necessary to set an ejector pin in the mold, thereby avoiding burrs generated by the ejector pin gap, making the workpiece surface smoother. Overall, the function is more complete.
