Description

Technical Field

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

[0002] Die-casting equipment is a highly efficient process that uses high pressure to rapidly inject molten metal into a precision mold, cooling it quickly to form the mold. It is primarily used to produce metal parts with complex shapes, precise dimensions, and smooth surfaces. Its characteristic is that the molten metal is heated in an external furnace and then injected into the mold via an injection mechanism. Die-casting equipment primarily consists of an injection system, a mold clamping mechanism, a hydraulic system, a control system, and the mold. The injection system uses a piston to force the molten metal into the mold cavity at high speed; the mold clamping mechanism ensures the mold closes precisely under high pressure; and the hydraulic system provides power.

[0003] The casting equipment in the existing technology needs to be demolded after cooling is completed. Some large-scale continuous casting equipment uses a push rod to push out the product, which needs to be grasped after being pushed out. Due to the poor grasping stability at the edge of the product, some use vacuum suction cups for grasping, which are easy to fall, resulting in damage during discharge and reducing the yield rate.

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

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1: Reference Figures 1-10 The rapid demoulding casting device shown includes two casting molds 1. The casting mold 1 includes a movable mold 11 and a fixed mold 12. The movable mold 11 can move to close the mold with the fixed mold 12.

[0043] The fixed die 12 is fixedly mounted on and connected to an input pipe 2, and a movable punch 10 is provided in the input pipe 2;

[0044] The two casting molds 1 are connected to a demoulding assembly 3, which includes an ejection rod 31 and a fixing rod 32. The ejection rod 31 and the fixing rod 32 are engaged with each other by a snap fit, and the ejection rod 31 can move horizontally to eject the fixing rod 32 from the casting mold 1;

[0045] A clamping assembly 4 is provided on the demoulding assembly 3, and the clamping assembly 4 can move. The clamping assembly 4 includes two clamping bars 41, and the two clamping bars 41 can be moved vertically to the two sides of the corresponding fixed rod 32. The two clamping bars 41 can move close to each other to clamp the fixed rod 32, and the fixed rod 32 can be detached from the ejection rod 31 after clamping.

[0046] The movable mold 11 moves to close the mold with the fixed mold 12, and the aluminum liquid is passed into the input pipe 2. The punch 10 moves in the input pipe 2 to push the aluminum liquid in the input pipe 2 into the fixed mold 12 at high speed, and cools and forms in the fixed mold 12. After forming, the movable mold 11 moves to open the mold. During the mold opening process, the two ejection rods 31 move from the corresponding movable mold 11 and the fixed mold 12, driving the fixed rod 32 to move and push the molded product out of the mold cavity. During the ejection process, the fixed rod 32 is located on both sides of the molded product to fix the molded product. The two clamping bars 41 move downward to both sides of the fixed rod 32, and then the two clamping bars 41 move close to each other to clamp the fixed rod 32. After being clamped, the fixed rod 32 is separated from the corresponding ejection rod 31, and 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.

[0047] When the casting is formed, it can be pushed out of the mold cavity by the ejection rod 31 and the fixing rod 32, which makes demoulding faster and reduces the degree of manual intervention. During the demoulding process, both sides of the casting are always fixed by the fixing rod 32 to prevent the casting from falling and being damaged after demoulding, thereby improving the yield rate. After the demoulding is completed, the fixing rod 32 is clamped by the clamping assembly 4, and the fixing rod 32 is separated from the ejection rod 31. The fixing rod 32 in the clamping assembly 4 keeps clamping the casting and moving it together to discharge the material, thereby ensuring the stability of the casting during the discharge process.

[0048] Example 2, reference Figures 1-10 , which is different from the above embodiment, is that the clamping assembly 4 also includes two clamping cylinders 43, a sliding plate 44, a fixed frame 45, a horizontal cylinder 46 and a vertical cylinder 47. The sliding plate 44 is fixedly mounted on the output end of the vertical cylinder 47, and the fixed frame 45 is slidably fitted on the sliding plate 44. The two clamping cylinders 43 are both fixedly mounted on the fixed frame 45. The fixed frame 45 is provided with an avoidance groove at the position corresponding to the fixed rod 32. The two clamping bars 41 are respectively fixedly mounted on the output ends of the corresponding clamping cylinders 43, the horizontal cylinder 46 is fixedly mounted on the sliding plate 44, and the fixed frame 45 is fixedly mounted on the output end of the horizontal cylinder 46.

[0049] The vertical cylinder 47 drives the sliding plate 44 to move vertically, and the sliding plate 44 drives the fixed frame 45 and the clamping bar 41 to move vertically, so that the clamping bar 41 is located on both sides of the fixed rod 32, and the clamping cylinder 43 drives the clamping bar 41 to move, so that the two clamping bars 41 are close to each other to clamp the fixed rod 32.

[0050] A clamping block is fixedly mounted on the clamping strip 41 at a position corresponding to the fixing rod 32 , and one side of the clamping block is arc-shaped.

[0051] The clamping bar 41 drives the clamping block to move horizontally, so that the clamping block abuts against the fixing rod 32 to clamp the fixing rod 32.

[0052] The clamping bar 41 clamps the fixed rod 32, driving the fixed rod 32 and the casting to move. When the casting moves to the unloading position, the horizontal cylinder 46 drives the fixed frame 45 to move, the fixed frame 45 drives the clamping bar 41 to move, and the clamping bar 41 drives the fixed rod 32 to move, so that the fixed rods 32 on both sides of the casting move in opposite directions, loosening the clamping of the casting, and the casting is unloaded. The clamping assembly 4 drives the fixed rod 32 to move to the position of the casting mold 1 and connects with the ejection rod 31.

[0054] After the two clamping bars 41 move to both sides of the fixed rod 32, the clamping bars 41 correspond to the extrusion plates 35, and the two clamping bars 41 move closer to each other. The clamping bars 41 push the extrusion plates 35 to move, and the extrusion plates 35 drive one end of the connecting rod 34 to move. Because the extrusion plates 35 cannot move horizontally, the other end of the connecting rod 34 drives the center rod 36 to move, and the center rod 36 drives the locking rod 33 to move, so that the locking rod 33 disengages from the lock groove, allowing the fixed rod 32 to disengage from the ejection rod 31.

[0055] Example 4, reference Figures 1-10 , which is different from the above embodiment, the demolding assembly 3 also includes a stabilizing rod and a reset spring 38. The stabilizing rod is fixedly installed in the fixing rod 32, and the stabilizing rod is inserted in the center rod 36 and slides with the center rod 36. One end of the reset spring 38 is fixedly installed on the fixing rod 32, and the other end of the reset spring 38 is fixedly installed on the center rod 36.

[0056] When the clamping bar 41 drives the central rod 36 to move through the extrusion plate 35 , the central rod 36 drives the return spring 38 to store force.

[0057] A connecting groove is provided at the top of the ejection rod 31, and the locking rod 33 slides in the fixing block 37. When the fixing rod 32 is connected to the ejection rod 31, the fixing block 37 is located in the fixing groove, the locking rod 33 is located in the locking groove, and the fixing cylinder is located in the connecting groove.

[0058] When unloading, the clamping bar 41 clamps the fixing rod 32, and then the clamping assembly 4 drives the fixing rod 32 to move upward, and the fixing rod 32 drives the fixing cylinder, the center rod 36, the fixing block 37 and the locking rod 33 to move upward, and the fixing cylinder disengages from the connecting groove, and the fixing block 37 disengages from the fixing groove, thereby disengaging the fixing rod 32 from the ejection rod 31.

[0059] After the casting is unloaded, 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 tube enters the connecting groove, the fixing block 37 enters the fixing groove, the clamping bars 41 move away from each other, and the fixing rod 32 is released. The reset spring 38 pushes the center rod 36 to move, and the center rod 36 drives the locking rod 33 to enter the locking groove. The fixing rod 32 is connected to the ejection rod 31, and the connection is more stable.

[0060] Example 5, with reference to Figures 1-10 , which is different from the above embodiment, is that a demoulding hydraulic cylinder is fixedly installed in the casting mold 1, and the ejection rod 31 is fixedly installed at the output end of the demoulding hydraulic cylinder, so that the ejection rod 31 and the fixed rod 32 can be moved into the casting mold 1, and the fixed rod 32 matches the casting mold 1.

[0062] The moving motor 62 drives the moving screw 63 to rotate, the moving block 64 moves on the moving screw 63, the moving block 64 drives the moving plate 65 to move, and the moving plate 65 drives the vertical cylinder 47, the fixed frame 45 and the clamping bar 41 to move. When discharging, the clamping bar 41 drives the casting to move to the outside of the casting casing 5 through the fixed rod 32 for unloading, which is convenient for conveying the casting and will not affect the casting process.

[0066] After molding, the movable mold 11 moves to open the mold. During the mold opening process, the two ejection rods 31 move from the corresponding movable mold 11 and fixed mold 12, driving the fixed rod 32 to move and eject the molded product from the mold cavity;

[0067] During the ejection process, the fixing rods 32 are located on both sides of the molded product to fix the molded product, and the two clamping bars 41 move downward to both sides of the fixing rods 32. Then, the two clamping bars 41 move closer to each other to clamp the fixing rods 32. After being clamped, the fixing rods 32 are separated from the corresponding ejection rods 31.

[0068] The clamping assembly 4 drives the fixing rod 32 to move upward. The fixing rod 32 is located on both sides of the casting plate to fix the casting plate. The clamping bars 41 clamp the fixing rod 32 to drive the fixing rod 32 and the casting plate to move.
