Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] see figure 1 , the present invention provides a control method S10 for ejecting and ejecting the printer bottom case from the mold, which is used to control the ejection and demoulding of the printer bottom case to take out the printer bottom case, which includes:

[0035] Step S11, detecting whether the injection mold leaves the mold;

[0036] Step S12, if yes, control the ejection mechanism of the injection mold to eject the bottom shell of the printer in 1-2 stages at an ejection speed of 10-40 mm / s.

[0037] It should be noted that, in the printer bottom case and its injecti...

Abstract

The invention discloses a printer bottom shell and an injection molding ejecting and demolding control method thereof. The injection molding ejecting and demolding control method of the printer bottomshell is used for controlling ejecting, demolding and taking out of the printer bottom shell. The method comprises the steps that whether an injection mold leaves a mold or not is detected; and if yes, an ejecting mechanism of the injection mold is controlled for ejecting the printer bottom shell in a one to two section manner at the ejecting speed of 10-40 mm / s. According to the injection molding ejecting and demolding control method of the printer bottom shell, by means of section ejecting and demolding, the structure completeness of the printer bottom shell and the injection mold are effectively protected, the yield of injection molding of the printer bottom shell is increased, the service life of the injection mold is prolonged, and the injection molding cost of the printer bottom shell is reduced.

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 a method for controlling ejection and demoulding of injection molding 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, then inject the glue, and finally control the opening of the injection mold, and then control the ejector mechanism to separate the bottom case of the printer from the injection mold to complete the ejection and demoulding of the bottom case of the printer; [0003] However, in the existing injection molding process, when the bottom case of t...
