Description

Technical Field

[0001] The utility model relates to the technical field of aluminum die casting processing, in particular to an auxiliary device for stamping aluminum die castings. Background Art

[0002] Aluminum die castings are a type of pressure-cast parts. They are made using a pressure-casting mechanical die-casting machine equipped with a casting mold. The heated liquid aluminum or aluminum alloy is poured into the inlet of the die-casting machine. The die-casting machine is die-cast to cast aluminum parts or aluminum alloy parts of the shape and size restricted by the mold. Such parts are usually called aluminum die-castings.

[0003] However, when the existing aluminum die-casting stamping equipment is used, the aluminum die-casting to be stamped is usually placed directly on the fixed die, and then the aluminum die-casting is stamped using the die. However, when the die contacts the aluminum die-casting, the position of the aluminum die-casting will change with the movement of the die, and the aluminum die-casting will tilt, which has a certain impact on the processing quality of the aluminum die-casting. At the same time, when the die is stamping the aluminum die-casting, the fixed die for forming the aluminum die-casting is subjected to the impact force of the die for a long time, which has a certain impact on the service life of the fixed die. Therefore, an auxiliary device for stamping the aluminum die-casting is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide an auxiliary device for stamping aluminum die-castings. The utility model solves the problems that the existing aluminum die-casting stamping equipment is inconvenient to limit the aluminum die-castings to be processed when in use, and it is inconvenient to buffer the impact force generated by the punching of the aluminum die-castings, and the fixed mold for forming the aluminum die-castings is easily damaged by arranging a motor, a transmission rod, a drive rod A, a drive rod B, a plate frame A, a plate frame B, a buffer spring A, a buffer spring B, a buffer plate, a telescopic rod, a rubber block and a bidirectional screw.

[0008] By adopting the above technical solution, when the fixed plate drives the die to punch the aluminum die-casting on the fixed die, the fixed block outside the fixed plate presses the buffer plate on the plate frame B, and then the buffer plate drives the connecting sleeve to slide outside the vertical rod, and the connecting sleeve presses the buffer spring A outside the vertical rod, and then the buffer spring A is compressed, and at the same time the buffer plate squeezes the rubber block inside the plate frame B, thereby buffering the downward impact force of the die, thereby facilitating the protection of the fixed die on the operating table.

[0009] Specifically, support sleeves are welded to the outside of the driving frame A and the driving frame B, and support rods that enable the driving frame A and the driving frame B to move stably are slidably connected to the inner side of the support sleeves.
