A method for efficiently processing the tooth pattern on the surface of the knob mold

Abstract

The invention discloses a method for efficiently processing the tooth-shaped pattern on the surface of a knob mold, including mold design and processing: the mold adopts a detachable design and includes a mold core, an insert and a slider, and the matching inserts and sliders are respectively processed. Slider, and the insert hole and the T-slot to match the slider are processed on the core of the mold; electrode design: the electrode is designed as a single electrode, and the single electrode has a complete tooth pattern structure, and machining the electrode; and slider assembly and positioning and electric discharge forming. The invention designs a single electrode, which can be disassembled and assembled at one time during discharge, avoiding repeated disassembly, calibration and edge-seeking collisions, thereby saving manpower and material costs, improving processing accuracy, and achieving the purpose of reducing costs and increasing efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a method for efficiently processing tooth patterns on the surface of a knob mould. Background technique [0002] With the development and progress of economy and technology, cars are becoming more and more popular, and most cars are equipped with knobs, which can be used as control buttons to control and adjust gears, air conditioning, multimedia, etc. The surface of the knob is often provided with a tooth pattern, and the tooth pattern mainly plays the role of increasing the friction force, increasing the touch and adjusting the feel. [0003] The manufacture of knobs is often formed by molds. Among them, the processing of tooth patterns on the knob molds has become a key and difficult point. At present, most of the tooth patterns on the mold are processed by electrode discharge machining, and the mold includes a mold core and a slider. The slider is prov...

AI Technical Summary

Problems solved by technology

The existing processing method has the following defects: one is that the number of electrodes is large and the number of disassembly and assembly is many, each time the electrode and the slider are replaced, it needs to be re-calibrated and the number of touches is divided, which greatly reduces the production efficiency; the other is that due to Electrodes and sliders need to be disassembled and calibrated many times, resulting in an increase in the cumulative error of processing and affecting the appearance and accuracy of the product
