Machining method of slider insert

Abstract

The invention provides a machining method of a slider insert. The machining method of the slider insert comprises the following steps that a slider insert workpiece is machined according to the designsize of the slider insert; the slider insert workpiece is placed in a clamp of a grinding machine to be fixed; a grinding wheel machining track is obtained, and a grinding wheel of the grinding machine carries out secondary machining on the slider insert workpiece according to the grinding wheel machining track so as to remove a thread undercut on an internal thread of the slider insert; the stepof obtaining the grinding wheel machining track comprises the steps that an analysis model of the slider insert is established; according to the analysis model, the position of a thread undercut critical point is calculated; and the grinding wheel machining track is generated according to the position of the thread undercut critical point. According to the machining method of the slider insert, the grinding wheel machining track is established and generated according to the analysis model of the slider insert, and the grinding wheel of the grinding machine carries out secondary machining on the slider insert workpiece according to the established grinding wheel machining track so as to remove the thread undercut on the internal thread of the slider insert workpiece, so that a product external thread is prevented from being damaged by the undercut, and product release is facilitated.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a method for processing slider inserts. Background technique [0002] The external thread on some injection molded products will be processed through two slider inserts. Specifically, such as figure 1 As shown, the slider insert 10 is provided with a semicircular hole 11, and the inner wall of the semicircular hole 11 is provided with an internal thread 12, so that when the two slider inserts are molded together, a complete screw hole is formed. When the product is injection molded , the internal thread in the screw hole will form a corresponding external thread on the outer wall of the product. For example, figure 2 In the lens barrel product shown, the external thread of the lens barrel is molded at the center of the product, and the external threads on both sides of the parting line (center line) are molded by two sliders. [0003] Because burrs are easy to be produced at ...
