Abstract

The invention discloses a printer bottom case and an injection molding control method thereof. The printer bottom case injection control method is used to control an injection molding machine to prepare the printer bottom case. Sectional closing mold; at injection pressure 20‑205kg / cm 2 With the injection speed of 5-75mm / s, the glue is injected in 1-5 sections for 1.5-11.5s; with the holding pressure of 47-57kg / cm 2 Press down for 0-8.5s; after cooling for 25-35s, open the mold in 1-5 stages. It can be understood that the above-mentioned printer bottom case injection molding control method of the present invention effectively protects the service life of the injection mold and reduces the production cost by closing the mold in sections; at the same time, the sol is fully Filling the injection mold, combined with segmental mold opening, significantly improves the injection molding yield of the bottom case of the printer.

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 molding control method thereof. Background technique [0002] In daily work and life, printers have become more and more indispensable equipment. With the development of technology, people have higher and higher requirements for the appearance of printers, which requires that the printer shell must have surface saturation and smoothness; Most of the existing printer casings are prepared by injection molding, but the printer casings, especially the printer rear casings, are equipped with complex thin-walled structures, inclined roof structures or thin inclined structures in order to accommodate and install the internal parts of the printer. . [0003] In the existing injection molding process, in order to meet the above structure, the injection mold is often provided with a separate front mold and rear mold, and the...
