Abstract

The invention discloses a fixture for a punching pin of a mold and relates to the field of hardware accessories of molds. The fixture comprises a fixture body, a stop pin, an adjusting rod and a toothed plate, wherein a mounting hole for mounting of the punching pin of the mold is axially formed in the fixture body; the toothed plate is placed in the mounting hole; a stop pin hole is further formed in the fixture body, is higher than the toothed plate and is led to the mounting hole from the revolving surface of the fixture body; an adjusting cavity is further formed in the fixture body; an adjusting gear is arranged in the adjusting cavity, is turned by the aid of the adjusting rod and is meshed with the toothed plate to enable the toothed plate to move up and down. The fixture for the punching pin of the mold is reasonable in structure and compact in matching, the problem that a broken punching pin cannot be taken out can be solved, structure damage is prevented, and the service life of equipment is effectively prolonged.

Description

technical field [0001] The invention relates to the field of mold hardware accessories, in particular to a fixture for punching pins of a mold. Background technique [0002] The punching needle is an indispensable accessory when the stamping die is working. It is a replaceable die consumable. It is installed on the stamping die for continuous punching, stamping and punching operations, so that the processed material is separated or plastically deformed, so as to obtain the required finished or semi-finished products. The punching pin locking mechanism is mainly used in the precision assembly punching process of the hard disk magnetic head industry. It adopts the principle of circular hole line positioning and screw locking to achieve the purpose of fixing the punching pin. Using the principle of line positioning cannot guarantee the coaxiality of the punching needle, and the use of screw locking cannot control the force, resulting in poor consistency of punching needle clam...
