The invention provides a processing method of a slider insert, comprising: processing a slider insert workpiece according to the design size of the slide block insert; placing the slide block insert workpiece in a fixture of a grinding machine for fixing; obtaining a grinding wheel for processing track, and make the grinding wheel of the grinding machine carry out secondary processing on the workpiece of the slider insert according to the grinding wheel processing track, so as to remove the thread undercut on the internal thread of the slider insert; wherein, the steps of obtaining the grinding wheel processing track include: establishing the slide The analysis model of the block entry; according to the analysis model, the position of the critical point of thread undercut is calculated; according to the position of the critical point of thread undercut, the grinding wheel processing trajectory is generated. The present invention establishes and generates the grinding wheel processing track according to the analysis model of the slider insert, and allows the grinding wheel of the grinding machine to perform secondary processing on the slider insert workpiece according to the established grinding wheel processing track, so as to remove the internal thread of the slide block insert workpiece. The screw teeth are undercut, so as to avoid the undercut to damage the outer thread of the product, and facilitate the release of the product.
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, 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. E.g, 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 the mold-clos...
