Description

Technical Field

[0001] The utility model belongs to the technical field of positioning processing, in particular to an automatic wire cutting positioning device for plastic mould processing. Background Art

[0002] Wire cutting, also known as linear electric spark cutting, is a method of processing based on the principle of continuous discharge, using electrode wire as a cutting tool. Wire cutting requires a positioning device to position and fix the plastic mold, but if the traditional positioning device is not exposed at both ends, the wire cutting cannot be fully performed.

[0003] After searching, the Chinese patent document (authorization announcement number CN216758480U) discloses a wire cutting positioning mechanism for processing plastic mold parts, including a box, a screen, a debris discharge port, an L-shaped support rod and a connecting block. A screen is fixedly arranged above the inner surface of the box, a debris discharge port is provided through the left surface of the box, an L-shaped support rod is fixedly arranged on the inner surface of the box, and a connecting block is fixedly arranged in the center of the outer surface of the L-shaped support rod; by placing the workpiece between the second fixed plate and the clamping plate, turning the adjustment bolt so that the clamping plate cooperates with the second fixed plate to fix the workpiece, the sliding plate is driven to move by the electric telescopic rod to determine the position of the workpiece, and then the positioning bolt is turned so that the positioning bolt drives the positioning plate to move to the right, and the positioning plate is closely attached to the left surface of the sliding plate to achieve the positioning effect. After taking out the workpiece in the middle, the sliding plate can be driven by the electric telescopic rod to be closely attached to the positioning plate to restore the original position of the workpiece, and the workpiece restoration accuracy is higher. The two ends of the positioning device are not exposed, so the wire cutting cannot be fully performed. Utility Model Content
