Three-dimensional one-time spraying method

Abstract

The invention discloses a three-dimensional one-time spraying method which includes the following steps that firstly, an article to be sprayed is put into a die, the die comprises an inner cavity defined by an upper die body and a lower die body, a shaft hole for a rotating shaft to penetrate is formed in the top end of the upper die body, a protruding pillar used for installing the article to be sprayed is arranged on the inner wall of the upper die body, the bottom end of the lower die body is provided with a shaft hole for the rotating shaft to penetrate, and hollow holes for spraying are formed in the upper die body and the lower die body; secondly, after the upper die body and the lower die body are buckled together, the upper die body and the lower die body are installed on the rotating shaft through the shaft holes in the upper die body and the lower die body; thirdly, the die is rotated, and the article to be sprayed is sprayed through the hollow holes formed in the die. According to the three-dimensional one-time spraying method, the article to be sprayed is put into the die, the hollow holes are formed in the die to conduct spraying, needed patterns can be sprayed on the article at a time, the spraying efficiency is improved, the manufacturing cost is low, and the spraying effect is good.

Description

technical field [0001] The invention relates to a spraying method, more precisely, relates to a one-time spraying method on a three-dimensional surface. Background technique [0002] In the prior art, when spraying a pattern on a three-dimensional solid, due to the discontinuity of the pattern, it is impossible to perform a one-time spectrum on the three-dimensional solid, and it can only be done in the form of multiple spraying. For example, when spraying the surface of a sphere, spray a pattern first, then use related parts to block, and then spray another pattern. This spraying method has low work efficiency and high cost. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a three-dimensional disposable spraying method. [0004] In order to achieve the above object, the technical solution of the present invention is: a three-dimensional one-time spraying method, comprising the following steps: [0005] a...
