Abstract

The invention discloses a spraying jig which comprises an upper cover and a lower cover, wherein the lower cover is provided with a plurality of first positioning posts; the upper cover is provided with a plurality of first positioning holes corresponding to the first positioning posts; the upper cover is also provided with a plurality of spraying grooves used for exposing products to be sprayed and a plurality of yielding holes; the jig also includes screw caps which form locking structures with the first positioning posts; the upper cover is formed by etched molding. The invention further discloses an etching process applied to the upper cover of the spraying jig and a spraying process using the spraying jig for spraying. The spraying jig is simple in design, mature in technology, simple to manufacture, low in cost, high in production efficiency, easy to store and not liable to damage; the jig is infinitely reusable, and undesirable phenomena of spraying leakage or oil accumulation of the product due to over coverage do not occur no matter how complex the product is.

Description

technical field [0001] The invention relates to a spraying jig, in particular to a spraying jig, an etching process for the upper cover of the jig, and a spraying process using the spraying jig. Background technique [0002] In plastic surface treatment, spraying fixtures are needed to load products to assist spraying, and the existing spraying fixtures are all plastic spraying fixtures. However, plastic spraying fixtures have been used to design mold structures, edit tool paths, CNC, lathes, discharge, wire cutting, electroplating or polishing, assembly, testing, mold testing, injection molding, clamping, spraying and other production processes. With the development of the spraying market, spraying technology and equipment will become more and more mature. In the fierce competition environment, the market has greatly improved the spraying effect and quality requirements of products. High-quality spraying has become an irresistible development trend. . The production proce...
