Molding process of plastic arts lamp

Abstract

The invention discloses a molding method for a modeling art lamp. Firstly, a production mold is produced according to the shape of the modeling art lamp, then the surface of the production mold is dripped with PS plastic to form a modeling shell, then the modeling shell is decomposed to take out the production mold, then a decomposed part of the modeling shell is assembled by a PS dripping adhesive to produce two half PS plastic shells, and finally a light string is fixed into the PS plastic shell by a hot melt adhesive; and secondly, the PS dripping adhesive is used for sealing to ensure that the two half PS plastic shells are integrated into a whole to form the modeling art lamp with sharp and clear outline, vivid and realistic image, and strong appreciation and decoration. The adoption of the technological method does not need wound and weld an iron stands, the light string does not need use high temperature resistant electric wires, production technology is simple, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a lamp, in particular to a molding method of a plastic art lamp. Background technique [0002] For decoration, there are many plastic art lamps that imitate animal shapes on the market. The practice of this type of plastic art lamp is to wind and weld iron wires to form an iron frame of a predetermined shape, and then bind the light strings to the inside of the iron frame. , and finally drop plastic PS plastic (polystyrene) on the iron frame to make it shape, but the disadvantages of this method are: [0003] 1. Because the iron frame needs to be wound and welded according to the predetermined shape at first, the process is complicated and the production cost increases. [0004] 2. Since the light string is first bound to the inner side of the iron frame, and then PS plastic is dripped on the iron frame, the light string must use high temperature resistant wires, because the price of high temperature...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the iron frame needs to be wound and welded according to the predetermined shape first, the process is complicated and the production cost increases

[0004] 2. Since the light string is first bound to the inner side of the iron frame, and then PS plastic is dripped on the iron frame, the light string must use high temperature resistant wires, because the price of high temperature resistant wires is much higher than that of ordinary wires, resulting in The production cost of this kind of plastic art lamp is high

[0005] 3. Due to the blurred outline of the iron frame, the outline of the molded body after drop molding is also blurred, the image is not realistic, and the ornamental and decorative properties are not good.
