The invention relates to the technical field of illuminating lamps, and discloses a manufacturing method of an atmosphere lampshade. The method comprises the steps that firstly, material is baked, then the color and luster of the baked material are observed, after the color and luster meet the requirement, the next step of material storing is carried out, pressure and speed cooperate with each other in the material storing process, the baked material can be used for continuously and stably performing the next step of glue injection, the glue injection dotting process is the slow forming process of the lampshade, after part of the lampshade is subjected to glue injection dotting, a spray gun of an injection molding machine is rotated to start manufacturing of next part of the lampshade, therefore, the S3 is a continuously repeated process until the lampshade is completely formed through injection molding, and after the injection-molded lampshade is fully cooled, the lampshade is manufactured. By means of the atmosphere lampshade manufactured through the manufacturing method, the phenomena of bubbles, shrinkage, stripes and the like are avoided, the thick lampshade can be manufactured, the light condensation requirement can be met, and the lampshade has the effect of the colorful light with high penetrating power in cooperation with refraction textures on the surface of the lampshade.
Description
technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a method for manufacturing an atmosphere lampshade. Background technique [0002] Acrylic, also known as PMMA or plexiglass, is derived from English acrylic (acrylic plastic), and its chemical name is polymethyl methacrylate. It is an important plastic polymer material developed earlier, with good transparency, chemical stability and weather resistance, easy to dye, easy to process, and beautiful appearance. [0003] Acrylic lampshade is a lampshade made of acrylic as the main raw material. Acrylic material has outstanding optical transparency, good weather resistance, mechanical strength, electrical properties and chemical resistance, hardness 85-105HRM, excellent It has the advantages of excellent insulation performance, slow burning speed and no sparks. [0004] The advantages of acrylic lampshade are: acrylic lampshade has a very high refractive index and does not...
