Description

Technical Field

[0001] The present invention relates to the field of mechanical parts processing, and in particular to a die-casting ejection device of a hollow frame-shaped thin-walled sleeve. Background Art

[0002] In the field of mechanical parts processing, many parts have special structures, such as a hollow frame-type thin-walled die-casting. After the die-casting is formed, the lower round ejector of the die-casting equipment cannot eject the die-casting, and thus the demolding cannot be completed. For this type of hollow frame-type thin-walled die-casting, the conventional demolding methods are: 1. Setting a flat ejector, but due to the thin thickness of this type of ejector, it is very easy to break for the die-casting process that requires high temperature and high pressure. 2. Adding ejection auxiliary cylinders to the product wall, but this method will increase product characteristics, produce shrinkage marks, affect product appearance, and may interfere with assembly parts.

[0003] For example, a Chinese patent with publication number CN210280627U discloses a semi-solid magnesium-aluminum alloy hollow thin-walled casting molding control mechanism, including a base plate, a metal mold, and a gas pressure pump. The metal mold is composed of a first mold and a second mold. Support columns are arranged at the four corners of the upper end of the base plate, a low-pressure reactor is arranged in the middle position of the upper end of the base plate, a hydraulic cylinder is fixedly arranged at the upper end of the top plate, the lower end of the hydraulic cylinder driving end passes through the top plate and is fixedly connected to a hydraulic rod, the lower end of the hydraulic rod is fixedly connected to the first mold, the lower end of the connecting tube passes through the die-casting platform and is fixedly connected to the upper end of the low-pressure reactor, one side of the upper end of the low-pressure reactor is connected to a liquid inlet pipe, the other side of the upper end of the low-pressure reactor is connected to a pressure pipe, the pressure pipe is connected to the gas pressure pump, and liquid lifting pipes are arranged on both sides of the low-pressure reactor.

[0004] The above-mentioned molding control mechanism drives the ejector plate and the hydraulic rod through the hydraulic cylinder to eject the die-casting. However, for thin hollow thin-walled die-castings with a relatively thin thickness, one-time ejection can easily cause deformation of the die-casting, thereby resulting in a low product yield.

[0005] Therefore, there is a need for a die-casting ejection device that can avoid deformation of the die-casting during ejection and improve product yield. Utility Model Content

Further, the guide member 600 abuts against the first push plate 110, the first push plate 110 is provided with a through hole 110b, the ejector column 230 passes through the first avoidance hole 210c, the second avoidance hole 400c and the through hole 110b in sequence and then abuts against the guide member 600, the ejector column 230 is fixedly connected to the moving component 210, the rotating block 130 rotates when the moving plate 120 moves, and when the rotating block 130 rotates to a preset angle, it abuts against the moving component 210 , and then drives the moving component 210 to move, and at the same time the moving component 210 drives the ejection column 230 to move, and at this time the ejection column 230 ejects the guide member 600, and because the guide member 600 is connected to the product 10a, the product 10a is ejected secondary by the guide member 600, and thus the product 10a is ejected secondary by the first push plate 110 and the guide member 600, which ensures the normal ejection of the product 10a, avoids the deformation of the product 10a, and improves the product yield.

[0054] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
