A mosaic lampshade production process

Abstract

The invention discloses an embedded-type lampshade production process. The lampshade production process comprises the specific following steps: A, producing a supporting framework; B, carrying out surface treatment such as electroplating or coating on the supporting framework; C, carrying out surface treatment on a raw material of a silk weaving mold; D, customizing a full-cotton silk weaving mold according to the supporting framework; E, carrying out cold water treatment on the silk weaving mold, and wrapping and fixing the silk weaving mold onto the outer surface of the supporting framework; F, placing plastic raw materials into a feeding opening of a small-sized plastic extruder, heating the plastic raw materials after the plastic raw materials enter a screw part, smelting the plastic raw materials to a molten state, enabling a molten plastic wire to flow out of a discharging nozzle, manually moving the supporting framework and the silk weaving mold in the natural drooping process of the plastic wire, enabling the plastic wire to be uniformly distributed on the inner surfaces of the supporting framework and the silk weaving mold, and forming a plastic cover body by virtue of the plastic wire in one step; G, cooling and forming, then stripping the mold, and combining the plastic cover body and the supporting framework to form a lampshade; H, carrying out coloring treatment.

Description

technical field [0001] The invention relates to a production process of a lampshade, in particular to a production technique of a mosaic type lampshade. Background technique [0002] Lamps are ubiquitous in people's daily work and life, and are widely used. The structure of a lamp generally includes a lamp body and a lampshade arranged on the lamp body. It can be seen that the application of the lampshade is very extensive. Now popular in the market is a light-transmitting plastic lampshade formed by pouring molten plastic filaments on the surface of the mold and joining together. The production process of such a plastic lampshade is generally as follows: put the plastic raw materials into a small plastic extruder for heating Make it reach the molten state, the plastic filament in the molten state flows out from the discharge nozzle of the small plastic extruder, and the plastic filament in the molten state naturally falls to the outer surface of the prefabricated mold.

Now popular in the market is a light-transmitting plastic lampshade formed by pouring molten plastic filaments on the surface of the mold and joining together. The production process of such a plastic lampshade is generally as follows: put the plastic raw materials into a small plastic extruder for heating Make it reach the molten state, the plastic filament in the molten state flows out from the discharge nozzle of the small plastic extruder, and the plastic filament in the molten state naturally falls to the outer surface of the prefabricated mold. After the plastic filament is attached to the outer surface of the mold, it is cooled After molding, demoulding becomes the processing of the product. However, the objective disadvantage of this production process is that the product is formed by attaching to the outer surface of the mold, and the plastic filament is attached to the outer surface of the mold after being heated at a high temperature and then cooled and formed. , due to the basic principle of thermal expansion and cold contraction, it is easier to demould successfully after rapid demoulding. Otherwise, it will be difficult to demould successfully after the plastic lampshade is cooled. Then the mold of the product has the following basic requirements: High temperature, easy to shape, light, easy to demould

Based on the above requirements, the existing production process generally chooses resin materials as the mold material, because the resin can meet the above requirements, however, the easy release of the mold has greatly hindered the development of product form diversification. We know that the shape of the lampshade is divided into For the front and side, the impact of the resin mold on the front is relatively small. It can be round, square, and irregular, but there are relatively strict requirements on the side shape of the lampshade. The side shape of the lampshade must meet the upper diameter smaller than According to the requirements of the lower diameter, there are only two possible side shapes, the straight line shape with big top and small bottom or the arc shape with small top and big bottom. The mold cannot be demolded, which greatly hinders the diversified development of product structure, shape, style and size. The style is single and boring, the demoulding is cumbersome and complicated, the yield is low, the product quality is not stable and reliable, and the mold making is cumbersome and complicated, and the cost is high. , which greatly affects the production efficiency of the product, the production cost is high, and it is difficult to carry out mass production. Such a production process is traditional and old and is not suitable for promotion and application.
