Abstract

The invention discloses a grinding jig for ejector pins of plastic molds. The grinding jig comprises a base, a height adjusting seat, a locking mechanism and an ejector pin clamp. A mounting plate is vertically arranged on the base. The height adjusting seat capable of moving up and down is arranged on the lower portion of the mounting plate. The locking mechanism is arranged between the height adjusting seat and the mounting plate. The ejector pin clamp arranged on the upper portion of the mounting plate comprises a clamp base and movable press plates. The clamp base is fixedly connected with the mounting plate, a plurality of rectangular jaws are vertically arranged on the clamp base, V-shaped grooves in multiple sizes are formed in the side wall of each jaw, and the movable press plates are arranged in the jaws and are all fixedly connected to a press-plate base. Horizontal movement control of the press-plate base is realized through a horizontal movement mechanism. The grinding jig can meet multiple grinding requirements of different batches of ejector pins with different heights and different diameters.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold thimble grinding jig. Background technique [0002] As an indispensable accessory for plastic molds, ejector pins are widely used in plastic molds to separate products from the mold. The thimble often needs to be highly ground on the grinding machine. In order to facilitate the grinding of the thimble, it is necessary to use the thimble grinding jig to position, clamp and fix the thimble. Existing thimble grinding jigs generally include support plates, positioning jaws, movable pressure plates, handles, etc., and have simple structures and single functions. For different diameters, different heights, and different batches (single or multiple) of thimbles, it is often necessary to replace different jigs when grinding, resulting in waste of time, low processing efficiency, high labor intensity, and waste of cost. Contents of the invention [0003] The techn...
