Technology for polishing front-back die parting line on mobile phone battery cover

Abstract

The invention discloses a technology for polishing a front-back die parting line on a mobile phone battery cover. The technology comprises the following steps: I, preparing a polishing machine; II, preparing a rotary table; III, placing two to-be-polished mobile phone battery covers on a pair of processing stations; IV, driving two sponge grinding wheels to carry out profile modeling polishing on the to-be-polished mobile phone battery covers on the two processing stations by a motor under the control of a controller, and simultaneously, carrying out dripping lubrication and cooling on the two sponge grinding wheels through two water pipes; and V, after the profile modeling polishing, rotating the rotary table, and taking down polished products. Through the steps, the front-back die parting line on the mobile phone battery cover is polished; the technology has the following characteristics: dust and undesirable odor are avoided, water can be recycled, the production process is short, and the production cost is low; in addition, the product appearance defect is overcome, and the product visual aesthetic feeling is improved.

Description

technical field [0001] The invention relates to a polishing process, in particular to a polishing process for the parting line of the front and rear molds of the battery cover of a mobile phone. Background technique [0002] Mobile phone battery cover In the injection molding production process, the injection mold will form a front and rear mold parting line in the middle of the battery cover. If the front and rear mold parting lines are not eliminated, the appearance of the mobile phone battery cover will be seriously affected. [0003] The existing polishing process of the front and rear mold parting lines is very harmful to people and the environment. The production process will not only produce a large amount of dust, waste water containing polishing wax and a large amount of peculiar smell, so that the operators have to wear gas masks, and the polishing process The production process is long and the production cost is high. [0004] Therefore, the prior art needs to be...
