Description

Technical Field

[0001] The present invention relates to the field of casting equipment, and in particular to aluminum alloy plate casting equipment and an automobile plate casting method. Background Art

[0002] The core structure of aluminum alloy casting equipment (referred to as a die-casting machine) consists of an injection system, a clamping mechanism, a hydraulic power system, a mold, and a temperature control unit. Its principle is to inject molten aluminum alloy into a precision mold cavity at high pressure and speed, where it rapidly solidifies and forms the mold. The injection system comprises a pressure chamber, a punch, and a pressure intensifier. After molten aluminum is injected into the pressure chamber via a metering spoon, a hydraulically driven punch pushes the molten metal into the mold at extremely high speeds (up to 5-10 m / s). The pressure intensifier applies a pressure of 20-200 MPa during the filling phase to compensate for shrinkage and eliminate air holes. The clamping mechanism locks the mold using a hydraulic cylinder or toggle mechanism, ensuring a tight closure at the mold parting surface under high pressure.

[0003] Chinese patent application CN106735106A discloses a device for realizing mobile micro-die casting of metal components, comprising a die-casting environment box, an air inlet pipe provided at the top of the left side wall of the die-casting environment box, an exhaust pipe provided at the top of the right side wall of the die-casting environment box, an air guide pipe provided at the bottom of the right side wall of the die-casting environment box, and a vacuum device provided on the right side of the air guide pipe. Compared with existing devices for realizing mobile micro-die casting of metal components, the present invention has a simple structure and is easy to use. On the basis of existing devices for realizing mobile micro-die casting of metal components, a mold preheating sleeve is added, and the mold preheating sleeve is used to preheat the die-casting mold, thereby reducing the situation in which the casting loses fluidity due to sudden cooling during the die-casting process, resulting in failure to smoothly complete the filling of the mold, thereby affecting the production quality of the casting;

[0004] The above patents and prior art also have the following defects:

[0005] The molten metal liquid is injected into the mold cavity by applying pressure. The gate is usually set near the middle of the mold cavity. For some products with complex edges, the molten metal flows for a long time in the mold cavity, resulting in reduced cooling fluidity of the molten metal. In addition, the edge of the mold cavity is pressurized, making it impossible for the molten metal to quickly fill the mold cavity. The filling effect of the mold cavity edge is poor, resulting in defects such as gaps and pores on the edge of the product.

[0006] Therefore, the present application provides an aluminum alloy sheet casting equipment and an automobile sheet casting method to meet the needs. Summary of the Invention

The connecting plate 804 is provided in the movable pipe 803, the connecting valve plate 805 abuts against the connecting plate 804, and the connecting valve plate 805 has a connecting hole.

[0046] When the movable pipe 803 moves toward the cooling water channel, the blocking valve plate 802 is first separated from the blocking pipe 801, and then the connecting valve plate 805 is separated from the connecting plate 804;

[0049] The movable mold base 2 and the movable mold 4 move horizontally, the movable mold 4 and the fixed mold 5 are closed, and a mold cavity is formed between the movable mold 4 and the fixed mold 5. The molten aluminum alloy is poured into the material pipe 6 through the feed hole, and the punch 7 moves in the feed pipe 6. The punch 7 injects the molten aluminum alloy in the feed pipe 6 into the mold cavity at high speed. While the molten aluminum alloy is injected into the mold cavity, the fixed mold 5 and the movable mold 4 rotate, and the molten aluminum alloy is moved to the edge of the mold cavity by centrifugal force. The molten aluminum alloy is injected into the center of the mold cavity, so that the molten aluminum alloy quickly fills the mold cavity, thereby improving the molding efficiency, making the molten aluminum alloy have a good filling effect on the edge of the mold cavity, improving the molding quality of the product, and the product is not prone to bubbles and defects.

[0050] After the molten aluminum alloy is injected into the mold cavity of the movable mold 4 and the fixed mold 5, the fixed mold 5 and the movable mold 4 rotate to the initial position and stop.

Then the connecting valve plate 805 is removed from the connecting plate 804, and the opening of the movable pipe 803 is opened. The movable pipe 803 is connected with the cooling water channel. The movable pipe 803 on one side of the cooling water channel introduces cooling water into the cooling water channel. The cooling water will cool the molten aluminum alloy through the fixed mold 5 to form it. The cooling water is then discharged from the movable pipe 803 on the other side of the cooling water channel, which solves the cooling problem of the rotatable fixed mold 5, ensures the cooling effect of the product, and improves the molding efficiency and molding quality. When the fixed mold 5 rotates, the movable pipe 803 is separated from the cooling channel, and the cooling channel and the movable pipe 803 are respectively closed to prevent a large amount of cooling water from leaking and will not block the rotation of the fixed mold 5.

[0051] When the product is cooled and formed, the movable mold 4 moves to separate from the fixed mold 5, and the product is taken out. The spray pipe 10 sprays the release agent into the mold cavity of the fixed mold 5. At the same time, the fixed mold 5 rotates to make the release agent sprayed into the mold cavity more evenly.

The pushing tube 807 drives the blocking head to resist the blocking valve plate 802 and push the blocking valve plate 802 to move, and the blocking valve plate 802 is separated from the blocking tube 801. After the blocking valve plate 802 moves to the extreme position, the moving tube 803 continues to move, and the pushing tube 807 cannot move, while the moving tube 803 continues to move, so that the pushing tube 807 retracts into the moving tube 803 relative to the moving tube 803. The pushing tube 807 drives the connecting valve plate 805 through the connecting frame and compresses the connecting spring 808, so that the connecting valve plate 805 is separated from the connecting plate 804, and the cooling water enters the pushing tube 807 through the moving tube 803 and the connecting hole.
