Plastic product surface imitation metal automatic wire-drawing device and process

Abstract

The invention relates to the technical field of plastic product surface wire drawing, in particular to a plastic product surface imitation metal automatic wire-drawing device and a process. The process comprises the steps that firstly, a plastic product is formed in an injection molding manner through a mould; then the plastic product is subjected to paint spraying treatment; and then the surface of the plastic product is subjected to wire-drawing treatment through the automatic wire-drawing device. According to the device and process provided by the invention, the surface of the plastic product is subjected to wire-drawing treatment, a wire-drawing portion of the plastic product is in an inwards-concave wave shape, the situation that during carrying or transportation or using of the plastic product, the wire-drawing portion is damaged, paint is peeled off, and consequentially the product is probably scraped can be effectively avoided, and the production cost of enterprises is lowered; and in addition, the surface of the plastic product is directly coated with paint after injection molding of the plastic product is completed, then wire-drawing is performed, the gap between every two adjacent wave valleys is not filled with the sprayed paint, and the wire-drawing effect is improved.

Description

technical field [0001] The invention relates to the technical field of wire drawing on the surface of plastic products, in particular to an automatic wire drawing device and process for imitating metal on the surface of plastic products. Background technique [0002] Surface brushing treatment is a surface treatment method that forms lines on the surface of the workpiece by grinding products to achieve a decorative effect. Because the surface brushed treatment can reflect the texture of the material, it has been loved by more and more users and has become more and more widely used. [0003] The traditional wire drawing process is to increase the wire drawing part in the injection mold, so that during the injection molding process of the plastic product, the injection mold can form a wire drawing on the surface of the plastic product, and then spray paint. The cross section of the plastic product is as follows: figure 1 As shown, the wire drawing part is convex and wavy; how...

[0003] The traditional wire drawing process is to increase the wire drawing part in the injection mold, so that during the injection molding process of the plastic product, the injection mold can form a wire drawing on the surface of the plastic product, and then spray paint. The cross section of the plastic product is as follows: figure 1 As shown, the wire drawing part is convex and wavy; however, during the handling or transportation of these plastic products, the wire drawing crest part is easy to be touched and damaged, and the paint will fall off, causing the product to be scrapped. The gap between the two troughs is easy to fill with spray paint, which affects the drawing effect
