Description

Technical Field

[0001] The invention relates to the technical field of demoulding mechanisms, in particular to a demoulding mechanism for a special-shaped part and a method thereof. Background Art

[0002] Die casting is a metal casting process, which is characterized by using the mold cavity to apply high pressure to the molten metal, so that the molten metal fills the mold cavity under pressure, and is quickly formed into parts of a specific shape. Die casting usually produces nozzle waste and runner waste. Nozzle waste mainly refers to the part of the material that connects the metal product and the runner system during the casting process. When the metal product is removed from the mold, the nozzle part needs to be cut off, thereby generating nozzle waste. Runner waste refers to the waste generated by the channel part used to guide the molten metal from the nozzle of the die-casting machine into the mold cavity during the die-casting process. It has a relatively regular shape, generally in the shape of a tube or sheet, and can be recycled and reused after being cut and separated from the metal parts.

[0003] Chinese patent CN115946300A proposes a demoulding mechanism for a die-casting machine, including an upper mold and a lower mold arranged up and down, wherein a lower module is arranged on the lower mold, and an upper mold groove is arranged on a side of the upper mold close to the lower mold, and the lower module cooperates with the upper mold groove. The lower module is a trapezoidal block structure, and the elastic metal cylindrical rod forms an "eight" shape to "II" shape deformation tendency, and opens it outward from the position close to both sides of the two sets of side wing structures, so that the molded part can be smoothly separated from the lower module.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent uses an elastic metal cylindrical rod to form an "eight" shape to "II" shape deformation trend and open it outward from the positions close to both sides of the two sets of side wing structures, so that the molded part can be smoothly separated from the lower module. However, it cannot shear the runner waste after demolding, and cannot separate the metal parts and the waste.

[0006] 2. This patent cannot cool the punch while spraying the release agent, so that the metal part can be quickly shrunk and demolded.
