Technical Field

[0001] The utility model relates to the technical field of aluminum alloy die casting processing, in particular to a rapid demoulding device for aluminum alloy die casting production. Background Art

[0002] Aluminum alloy die-casting is a type of pressure-casting part. It is produced by pouring heated liquid metals such as copper, zinc, aluminum or aluminum alloy into the inlet of the die-casting machine using a pressure-casting machine equipped with a casting mold. The metals are then die-casted by the die-casting machine to produce copper, zinc, aluminum or aluminum alloy parts in the shape and size restricted by the mold. Due to its high production efficiency, aluminum alloy die-casting can be mass-produced in a short period of time. However, demolding of ordinary molds is not convenient enough, so special molds are required for processing and demolding.

[0003] At present, aluminum alloy die-casting is processed using die-casting molds. For example, Chinese patent announcement No. "CN220943128U" discloses a die-casting mold for thin-walled aluminum alloy die-casting parts, which includes a base plate with a groove formed inside. Two support columns are fixedly connected to the upper surface of the base plate, and a cross plate is fixedly connected to the upper surface of the support column. An upper mold is provided below the cross plate, and a lower mold is connected to the middle of the upper surface of the base plate. A cavity is formed in the middle of the upper mold and the lower mold.

[0004] However, during the die-casting process, it is difficult to remove the aluminum alloy die-casting from the current die-casting mold, and the temperature of the aluminum alloy die-casting is high, which makes it impossible for workers to remove the aluminum alloy parts from the mold in time, seriously affecting the processing efficiency of the aluminum alloy.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5 , a rapid demoulding device for producing aluminum alloy die-casting parts, comprising at least two mounting frames 1, at least two of the mounting frames 1 having fixed columns 2 fixed on their outer sides, and fastening mechanisms 3 are provided on both sides of the top of the mounting frame 1, the surfaces of the two fixing columns 2 are rotatably connected to connecting plates 4, a positioning mechanism 5 is provided between the two connecting plates 4 and the fixing columns 2, a top plate 6 is fixed between the two connecting plates 4, and a demoulding mechanism 7 is provided at the center of the top plate 6; the demoulding device can fix the mounting frame 1 on both sides of the mold by tightening the threaded columns 32 on both sides, and can rotate the top plate 6 inward to above the die-casting when demoulding, which not only does not affect the normal die-casting process, but also allows for convenient disassembly and assembly, without the need to remove the mold separately, and is very convenient to use. The die-casting can be adsorbed by the micro air pump 81 and the suction cup 72 and demoulded by the electric telescopic rod 71.

[0022] In this embodiment, the fastening mechanism 3 includes a threaded sleeve 31 connected to both sides of the top of the mounting frame 1. The inner side of the threaded sleeve 31 is threadedly connected to a threaded column 32. The bottom of the threaded column 32 is rotatably connected to a circular pressure plate 33. A knob 34 is fixed to the top of the threaded column 32. Turning the knob 34 can drive the threaded column 32 to rotate in the threaded sleeve 31. The threaded column 32 squeezes the circular pressure plate 33 downward and presses it tightly on both sides of the mold, making it convenient to fix the device.

[0023] Furthermore, the positioning mechanism 5 includes two positioning holes 51 and a fixing frame 52 distributed at a 90-degree angle. The two positioning holes 51 are located at the top and right side of the fixing column 2. The positioning holes 51 are opened on the surface of the fixing column 2. The fixing frame 52 is fixed to the outer sides of the two connecting plates 4. The inner side of the fixing frame 52 is slidably connected with a positioning rod 53 and a guide plate 54 is fixed on the surface of the positioning rod 53. The surface of the positioning rod 53 is sleeved with a spring 55 and the two ends of the spring 55 are respectively in conflict with the fixing frame 52 and the guide plate 54. The bottom of the positioning rod 53 passes through the fixing frame 52 and is engaged with the positioning hole 51. The positioning rod 53 can drive the guide plate 54 upward to squeeze the spring 55. The positioning rod 53 can be pulled out and inserted into another positioning hole 51, so that the top plate 6 can be rotated 90 degrees and positioned.

[0024] Furthermore, protrusions 10 are fixed on both sides of the positioning rod 53, and sliding grooves 9 are opened on both sides of the inner wall of the fixed frame 52, and the sliding grooves 9 are slidably connected to the protrusions 10.

One side of the micro air pump 81 is connected to a hose 82 and the other end of the hose 82 is connected to the suction cup 72. The micro air pump 81 can extract the gas in the suction cup 72, thereby increasing the suction force of the suction cup 72.

[0027] Working method: When demolding the die-casting, the staff places the mounting frames 1 on both sides of the mold, and then rotates the threaded column 32 by hand. The threaded column 32 can drive the circular pressure plate 33 to squeeze downward until it is tightened. Then the staff can start the electric telescopic rod 71 to drive the suction cup 72 to support the die-casting, and then start the micro air pump 81. The micro air pump 81 sucks out the gas in the suction cup 72 so that the suction cup 72 is tightly adsorbed on the die-casting. Then the staff can retract the electric telescopic rod 71, and the electric telescopic rod 71 can remove the die-casting. Then the staff can pull up the positioning rod 53, and the positioning rod 53 can drive the guide plate 54 upward to squeeze the spring 55. The positioning rod 53 can be pulled out and inserted into another positioning hole 51 to rotate the top plate 6 90 degrees and then position it. Then the micro air pump 81 can be turned off to loosen the die-casting and drop it. Then the die-casting process can be continued, and then the position of the suction cup 72 is reset to continue demolding.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
