Description

Technical Field

[0001] The utility model relates to a plastic mold and belongs to the technical field of molds. Background Art

[0002] In a small plastic mold using sliders, generally a pair of sliders work with the same molding part, that is, when a pair of sliders are driven to move toward each other to the mold closing position, the pair of sliders and the molding part together form a cavity of a molding point; when a pair of sliders are driven away from the molding part to the mold opening position, the pair of sliders are away from the molded plastic part to facilitate the removal of the plastic part from the molding point.

[0003] During the mold opening and closing process, one driving mechanism can only drive one slider, and a pair of sliders requires two driving mechanisms to drive. Each driving mechanism occupies a large mold size, which limits the number of cavities that can be set in the small plastic mold, which also leads to low production efficiency of existing small plastic molds.
