Punching tool for ejection block connecting rod fixing hole and use method thereof

Abstract

The invention belongs to the technical field of die machining and particularly relates to a punching tool for an ejection block connecting rod fixing hole and a use method thereof. The punching tool comprises an ejection block and a cylindrical punching die matched with the ejection block in use, wherein a rotation stopping groove is formed in the ejection block, and the punching die is clamp-connected in the rotation stopping groove. A guiding hole penetrating through the upper and lower surfaces of the punching die is formed in the punching die, and a rectangular rotation stopping face is arranged on the side face of the punching die. A rectangular clamp-fastening face matched with the rotation stopping face in use is arranged on the inner surface of the rotation stopping groove. The punching tool is simple in structure and convenient to use, a drilling process of the ejection block connecting rod fixing hole is optimized, the phenomenon is also avoided that the ejection block connecting rod fixing hole is eccentric due to improper manual operation, the punching quality and efficiency of the ejection block connecting rod fixing hole are improved, meanwhile the labor intensity ofworkers is also reduced, labor is saved, the ejection block punching cost is also reduced, and the punching tool is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of mold processing, and in particular relates to a punching tool for fixing holes of connecting rods of jack blocks and a use method thereof. Background technique [0002] The jacking block is a part of the mold ejection system, which is widely used in injection molds. During the mold manufacturing process, the jacking block connecting rod is connected and fixed with the jacking block connecting rod fixing hole on the jacking block, and the mold ejection action can be completed. At present, most of the fixing holes of the jacking block connecting rod are drilled on the jacking block, and most of them are programmed hole programs and machining point hole procedures. This kind of hole-pointing process not only requires the purchase of a large number of expensive hole-pointing equipment, but also requires workers to continuously debug and run related hole-pointing programs. This relatively increases the point ...

Problems solved by technology

This kind of hole-pointing process not only requires the purchase of a large number of expensive hole-pointing equipment, but also requires workers to continuously debug and run related hole-pointing programs.

This relatively increases the point hole cost of the fixing hole of the connecting rod of the top block, and also has higher requirements on the operating level of the workers.
