Abstract

The invention discloses a printer bottom shell and an injection mould opening control method thereof. The printer bottom shell injection mould opening control method is used for controlling an injection mould to open a mould to take out the printer bottom shell. The method includes the steps that whether the injection mould reaches a mould opening temperature or not is detected; and if yes, the injection mould is controlled to open the mould in 1-5 sections under the mould opening speed of 5-70 mm / s. That is, according to the printer bottom shell and the injection mould opening control method,through section-by-section mould opening, the structure integrity of the printer bottom shell and the injection mould is guaranteed effectively, the yield of the printer bottom shell injection is increased, the service life of the injection mould is prolonged, and the cost of the printer bottom shell injection is lowered.

Description

technical field [0001] The invention relates to the field of injection molding of printer casings, in particular to a bottom casing of a printer and an injection mold opening control method thereof. Background technique [0002] In daily work and life, printers are becoming more and more indispensable equipment. Most of the existing printer shells are prepared by injection molding process. Injection molds are indispensable for the injection molding process of printer bottom shells; in the injection molding process, first It is necessary to control the closing of the injection mold to form an injection space, and then inject the glue, and finally control the opening of the injection mold to take out the bottom case of the printer; but in the existing injection molding process, when the injection mold is controlled to open, the bottom case of the printer will stick Injection molds, combined with violent mold opening, often cause the bottom case of the printer to be torn or def...
