Problems solved by technology

[0005] (1) Plastic dehumidification is not complete, resulting in impurity marks prone to appear after the product is produced;
[0006] (2) After repeated rapid heating and cooling of the injection mold, the performance of hardness and toughness is reduced, which is easy to cause cracks in the mold;
[0007] (3) The cooling effect of the product is poor, the cooling time is long, the production efficiency is low, the cooling and shaping effect is poor, and it is easy to cause damage to the product during the ejection process

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] Such as figure 1 As shown, the present invention provides a method for injection molding of a lamp housing, comprising the following steps:

[0034] Step 100, the movable mold and the fixed mold are clamped, and the plastic melt is injected into the mold cavity formed by the mold clamping.

[0035] It should be added that, under the action of the drive system, the movable mold is closed along the slideway with the fixed mold, and at the same time, the ...

Abstract

The invention discloses a rubber injection molding method for a decorative lighting shell. The rubber injection molding method comprises the following steps of 100, closing a movable mold and a fixedmold and injecting a plastic melt into a mold cavity formed by mold closing; 200, conducting continuous pressure maintaining and cooling on the molds; 300, conducting demolding on an injection moldedproduct through a stripping mechanism. Through the method, plastics is subjected to pre-drying and dehydration, and the effect and quality of a plastic product can be improved; the molds are subjectedto segmented temperature regulation, the temperature regulation and control precision can be improved, the service life of the molds can be prolonged, the production quality is improved, and the high-temperature melt is protected against cracking caused by cooling; an external medium cooling method and a mold cooling method are combined to conduct cooling on a sprue to implement cooling on the product, and the shaping efficiency is improved. Accordingly, the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a method for injection molding of lamp decoration shells. Background technique [0002] Lighting is the eyes of the home. If there is no lamp in the family, it is like a person without eyes. A family without eyes can only live in darkness, so the position of the light in the home is very important. Nowadays, people call lighting fixtures as lighting fixtures. It can be seen from the title that lighting fixtures are not only used for lighting, but also can be used to decorate rooms. There are many types of lighting fixtures. From the living room , dining room, bedroom, kitchen and bathroom to aisle, balcony, bar! From indoors to outdoors, more to embellish the surrounding environment, the design styles of modern lighting fixtures are becoming more and more diverse, such as classical, modern, fashionable, European, American, refreshing, luxurious, and beautiful. This re...
