Description

Technical Field

[0001] The present invention relates to the field of casting equipment, and particularly relates to a casting equipment with rapid demoulding. Background Art

[0002] Casting equipment is a kind of high-efficiency casting equipment that uses high pressure to quickly inject molten metal into a precision mold and cool it into shape in a short time. It is mainly used for producing metal parts with complex shapes, precise dimensions, and smooth surfaces. Its characteristic is that the molten metal is injected into the mold by an injection mechanism after being heated by an external furnace. Die-casting equipment mainly consists of an injection system, a mold clamping mechanism, a hydraulic system, a control system, and a mold: the injection system injects the molten metal into the mold cavity at high speed through a piston; the mold clamping mechanism ensures that the mold is accurately closed under high pressure; the hydraulic system provides power for the equipment.

[0003] In the existing casting equipment, demoulding is required after cooling. Some large continuous casting equipment uses a push rod to push out, and after pushing out, it needs to be grabbed. Due to poor gripping stability at the edge of the product, some use a vacuum chuck for gripping, which is easy to drop, resulting in damage during discharging and reducing the qualified product rate.

[0004] Therefore, the present application provides a casting equipment with rapid demoulding to meet the requirements. Summary of the Invention

[0005] The purpose of the present application is to provide a casting equipment with rapid demoulding.

The clamping component includes two clamping strips. The two clamping strips can move vertically to both sides of the corresponding fixed rod, and the two clamping strips can move closer to each other to clamp the fixed rod. After the fixed rod is clamped, it can be separated from the push rod.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Refer to Figures 1 - 10 A casting device for rapid demolding as shown, including two casting molds 1. The casting mold 1 includes a moving mold 11 and a fixed mold 12, and the moving mold 11 can move to be combined with the fixed mold 12; An input pipe 2 is fixedly installed and communicated on the fixed mold 12, and a movable punch rod 10 is arranged in the input pipe 2; Demolding assemblies 3 are connected to both of the two casting molds 1. The demolding assembly 3 includes a push rod 31 and a fixed rod 32. The push rod 31 and the fixed rod 32 are in snap-fit, and the push rod 31 can move horizontally to push the fixed rod 32 out of the casting mold 1; A clamping assembly 4 is arranged on the demolding assembly 3. The clamping assembly 4 can move. The clamping assembly 4 includes two clamping strips 41. The two clamping strips 41 can move vertically to both sides of the corresponding fixed rod 32, and the two clamping strips 41 can move closer to each other to clamp the fixed rod 32. After the fixed rod 32 is clamped, it can be separated from the push rod 31.

[0022] The moving die 11 moves to close the mold with the fixed die 12. Molten aluminum is introduced into the input pipe 2. The punching rod 10 moves within the input pipe 2 to rapidly push the molten aluminum in the input pipe 2 into the fixed die 12, where it cools and forms. After forming, the moving die 11 moves to open the mold. During the mold opening process, the two ejector rods 31 move from the corresponding moving die 11 and fixed die 12, driving the fixed rod 32 to move and eject the formed product from the mold cavity. During the ejection process, the fixed rod 32 is located on both sides of the formed product to fix the formed product. The two clamping strips 41 move downward to both sides of the fixed rod 32, and then the two clamping strips 41 move closer to clamp the fixed rod 32. After the fixed rod 32 is clamped, it disengages from the corresponding ejector rod 31. The clamping assembly 4 drives the fixed rod 32 to move upward. The fixed rod 32 is located on both sides of the casting to fix the casting and drive the casting to discharge.

[0023] When the casting is formed, the casting can be ejected from the mold cavity through the ejector rod 31 and the fixed rod 32, with faster demolding and lower manual intervention. During the demolding process, both sides of the casting are always fixed by the fixed rod 32 to prevent the casting from falling and being damaged after demolding, improving the yield rate. After demolding is completed, the clamping assembly 4 clamps the fixed rod 32 and makes the fixed rod 32 disengage from the ejector rod 31. The fixed rod 32 in the clamping assembly 4 keeps clamping the casting and moves it out together, ensuring the stability of the casting during the discharging process.

[0024] Embodiment 2, referring to Figures 1 - 10 , which is different from the above embodiment in that the clamping assembly 4 further includes two clamping cylinders 43, a sliding plate 44, a fixed frame 45, a horizontal cylinder 46, and a vertical cylinder 47.

The two clamping strips 41 are respectively fixedly installed at the output ends of the corresponding clamping cylinders 43. The horizontal cylinder 46 is fixedly installed on the sliding plate 44, and the fixed frame 45 is fixedly installed at the output end of the horizontal cylinder 46.

[0025] The vertical cylinder 47 drives the sliding plate 44 to move vertically. The sliding plate 44 drives the fixed frame 45 and the clamping strips 41 to move vertically, so that the clamping strips 41 are located on both sides of the fixed rod 32. The clamping cylinders 43 drive the clamping strips 41 to move, so that the two clamping strips 41 move closer to clamp the fixed rod 32.

[0026] A clamping block is fixedly installed on the clamping strip 41 corresponding to the position of the fixed rod 32, and one side of the clamping block is arc-shaped.

[0027] The clamping strip 41 drives the clamping block to move horizontally, so that the clamping block abuts against the fixed rod 32 to clamp the fixed rod 32.

[0028] The clamping strip 41 clamps the fixing rod 32, driving the fixing rod 32 and the casting to move. When the casting moves to the blanking position, the horizontal cylinder 46 drives the fixing frame 45 to move, the fixing frame 45 drives the clamping strip 41 to move, and the clamping strip 41 drives the fixing rod 32 to move, causing the fixing rods 32 on both sides of the casting to move in opposite directions, releasing the clamping of the casting. The casting is blanked, and the clamping assembly 4 drives the fixing rod 32 to move to the position of the casting mold 1 and connect with the ejecting rod 31.

[0030] After the two clamping strips 41 move to both sides of the fixing rod 32, the clamping strips 41 correspond to the pressing plate 35. The two clamping strips 41 move closer to each other. The clamping strip 41 pushes the pressing plate 35 to move. The pressing plate 35 drives one end of the connecting rod 34 to move. Since the pressing plate 35 cannot move horizontally, the other end of the connecting rod 34 drives the central rod 36 to move. The central rod 36 drives the locking rod 33 to move, causing the locking rod 33 to disengage from the locking groove, enabling the fixing rod 32 to disengage from the ejecting rod 31.

The fixing cylinder disengages from the connecting groove, and the fixing block 37 disengages from the fixing groove, so that the fixing rod 32 disengages from the ejecting rod 31.

[0035] After the casting blanking is completed, the clamping assembly 4 drives the fixing rod 32 to reset. The vertical cylinder 47 drives the fixing rod 32 to move downward. The fixing cylinder enters the connecting groove, and the fixing block 37 enters the fixing groove. The clamping strips 41 move away from each other to release the clamping of the fixing rod 32. The return spring 38 pushes the central rod 36 to move. The central rod 36 drives the locking rod 33 to enter the locking groove.
