Description

Technical Field

[0001] The present application relates to the technical field of connecting seat production molds, and more specifically, to a production mold for a forklift component connecting seat. Background Art

[0002] As the main connecting part of forklift, the connecting seat is generally produced by stamping die. Stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping process, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the required parts.

[0003] After searching, the public (announcement) number: CN217912485U discloses a connecting seat production mold for forklift parts, which relates to the technical field of connecting seat production molds. In order to reduce the production cost of the production mold, the mold includes a lower mold, an upper mold and a side mold, and the upper mold is located directly above the lower mold... The application completes the workpiece forming and lower hole punching operations by the upper mold cooperating with the lower mold, and completes the side hole punching operation by the side mold cooperating with the lower mold. Compared with the traditional stamping mold, since the punching and forming are integrated operations, the high requirements of the stamping mold for precision are reduced, thereby indirectly reducing the production cost.
