Description

Technical Field

[0001] This utility model relates to the field of die casting equipment technology, and specifically to a die casting mold that is easy to demold. Background Technology

[0002] Die casting refers to the process of casting a mold by die casting metal under the action of other external forces. The main characteristics of die casting are that the metal fills the cavity under high pressure and high speed and is formed under high pressure. Currently, the sealing performance of the ejection mechanism is one of the key details in die casting production. During long-term use, the gap between the ejection mechanism such as ejector pins, ejector sleeves (ejector tubes), and push plates and the mold may be too large or due to wear, resulting in poor sealing. At the same time, poor sealing will cause thin, excess metal sheets to form after the casting cools, which are called "flash" or "burrs". Therefore, a die casting mold that is easy to demold is proposed. Utility Model Content

[0003] This utility model proposes a die-casting mold that facilitates demolding, solving the problem that the sealing performance of the ejection mechanism is one of the key details in die-casting production.

In summary, this technical solution avoids the problem of excessive clearance between the ejection mechanism and the mold, or poor sealing due to wear, during prolonged use.

[0029] The workflow for this application is as follows: Two sets of moving mechanisms on the surface of frame 2 are activated. The electric slide table 7 drives the die-casting mold 2 9 and moves the sliding block in the sliding groove, so that the die-casting mold 2 9 moves towards the center and precisely closes with the die-casting mold 1 8 inside the die-casting frame 1 to form a complete cavity. Multiple telescopic hydraulic cylinders 13 inside the die-casting frame 1 act synchronously, pushing the die-casting mold 1 8 to apply a huge clamping force to the die-casting mold 2 9 to ensure that the cavity remains sealed under high pressure. Subsequently, molten metal is injected into the cavity. While maintaining the mold closed, after the casting in the cavity cools and solidifies (the casting temperature needs to reach the appropriate electromagnet 16 before the following steps can be carried out, the casting can be air-cooled or water-cooled by external equipment), the multiple telescopic hydraulic cylinders 13 inside the die-casting frame 1 move synchronously, causing the die-casting mold 8 to move downward. At this time, the moving mechanism starts again, and the electric slide 7 drives the die-casting mold 9 to reset and separate from the die-casting mold 8, completing the mold opening. The multiple telescopic hydraulic cylinders 13 inside the die-casting frame 1 move synchronously, pushing the die-casting mold 8 upward. When the two sets of lifting components at the top of the frame 2 are working, the electric telescopic rod 10 extends and pushes the L-shaped connecting piece 20 to move downward along the guide rail 18, causing the electromagnet 16 on its surface to descend and magnetically connect to the casting in the die-casting mold 8. At the same time, multiple telescopic hydraulic cylinders 13 inside the die-casting frame 1 move synchronously, causing the die-casting mold 8 to move downward. At this time, the electric telescopic rod 10 pulls the L-shaped connecting piece 20 to move upward along the guide rail 18, causing the electromagnet 16 on its surface to rise, thus demolding the casting. When the horizontal moving mechanism is activated, the motor 14 drives the pulley 19 to rotate through the reducer 15, which in turn drives the adjusting belt 12, causing the entire adjusting frame 11 and its clamping mechanism to move directly above the casting. The two clamping mechanisms then begin to work. The electric slide rail on the stabilizing frame 21 drives the connecting plate 22 and the lever clamping cylinder 23 to move. The lever clamping cylinder 23 actuates, precisely clamping the casting on one side of the electromagnet 16. After the clamping mechanism clamps the casting, the electromagnet 16 stops working, the horizontal moving mechanism starts working again, the motor 14 reverses, and the clamping mechanism and the casting are smoothly moved out of the mold area together through the adjusting belt 12. The horizontal moving mechanism transports the casting to the top of the conveying mechanism. The clamping mechanism releases, and the casting is released onto the surface of the conveyor belt 5. The conveyor belt 5 continues to operate, transporting the casting to the next process.
