Embodiment Construction
[0026] figure 1 It is a schematic diagram of a preferred embodiment of the present invention—a flat-panel TV panel installation fixture. The method for manufacturing multi-color high-gloss transparent injection molded parts of the present invention is illustrated through the processing of the panel. The method includes the following steps—refer to figure 1 , figure 2 :
[0027] Step 1. Through ordinary injection molding equipment, an ordinary high-gloss injection mold is used for injection molding to obtain a panel 1 of a high-gloss and transparent flat-panel TV;
[0028] Step 2. After trimming the panel 1, the panel is transported to the fuel injection station by the transportation line, and the rear side of the panel is clamped by the positioning fixture 2;
[0029] Step 3. According to the design requirements, spraying paint and coloring processing are carried out on the first set surface of panel 1;
[0030] Step 4. After the oil spraying is completed, the positioning ...

The invention discloses a manufacture method of multicolor specular transparent injection molding pieces. The method includes the following steps of: (1) adopting a common specular injection mold for injection and obtaining a specular transparent injection molding piece; (2) adopting a positioning fixture to clamp the injection molding piece; (3) painting and coloring the set surface of the injection molding piece according to design requirements; (4) after the painting, dismantling the positioning fixture; and (5) repeating the steps from (2) to (4) and sequentially painting and coloring the set surface of the molding until the processing procedure is finished. By adopting common injection equipment and the common specular transparent injection mold, the invention obtains the transparent injection molding piece through injection, then installs the positioning fixture on the injection molding piece and sequentially implements batch painting and coloring process on the surfaces of the injection molding pieces according to product requirements, so as to lead the injection molding piece to be completely compared favorably with the two-colored specular injection molding piece produced by direction injection in the appearance texture, visual effect and the like. The production technique has the advantages of short production period, low process requirement, easy debugging, low manufacture cost and the applicability to producing multicolor injection molding pieces.
Description
technical field [0001] The invention relates to a method for manufacturing injection molding products, in particular to a method for manufacturing multicolor, high gloss and transparent injection molding products. Background technique [0002] Through oil injection, two-color injection molding and other methods, the TV can change from a single-color shell to a multi-color shell that is colorful, individual, and refreshing. This has become a development direction for TV shells that is obvious to all. High-gloss, transparent, and two-color TV casings are among the best. Currently, such shells are obtained by direct injection molding. The production method of the two-color transparent shell obtained by direct injection molding. Its main disadvantages are: [0003] (1) A special two-color high-gloss and transparent mold is required. The structure of the mold is complex, there are many auxiliary mechanisms, and the manufacturing cost is very high. Once a failure occurs, it is ...
