Problems solved by technology

[0002] The current production process of the back cover of the household TV is generally sheet metal stamping or plastic injection molding, and the plastic injection molding process accounts for more than 80%. The disadvantages of the injection molding process are that the injection mold is large, the mold opening time is long, and the mold cost is high. Under the market situation of rapid replacement of home appliances, it cannot meet the requirements of rapid product development

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0026] Such as Figure 1 ~ Figure 4 As shown, a blister-processed TV rear cover molding process includes the following steps:

[0027] Step 1. Select thermoplastic plastic sheet 2;

[0028] Step 2: Laminating or silk-screening texture treatment on the upper surface of the thermoplastic sheet 2 so that the upper surface of the thermoplastic sheet is pre-covered with a film layer or a silk-screen ink layer 1;

[0029] Step 3: Cut the thermoplastic sheet 2 after the pre-coated film layer or the silk screen ink layer 1;

[0030] Step 4: Heat and soften the cut pre-coated film layer or the thermoplastic sheet 2 of the silk screen ink layer 1;

[0031] Step 5. The lower surface of the softened pre-coated film layer or the thermoplastic sheet 2 of the screen printing ink layer 1 is bonded to the convex mold 5 of the TV back...

Abstract

The invention discloses a rear television cover machined by a plastic sucking process. A to-be-machined rear cover panel is subjected to surface laminating or texture screen printing before plastic sucking; the plastic sucking process is characterized in that a method of manufacturing an opened shell product by virtue of a thermoplastic plastic sheet is adopted, and the plastic sheet is cut into certain size, is heated to be softened, is attached to the contour surface of a specific mold after deformed by virtue of air pressure difference of two surfaces of the sheet or mechanical pressure, is subjected to cooling setting and is trimmed. The rear television cover machined by the plastic sucking process has the advantages that the machining process is simple, the machining mold is simple to develop, low in cost and short in developing period, and standardized design of formed parts is facilitated.

Description

Technical field [0001] The invention relates to the technical field of processing and forming a TV back cover, in particular to a forming process of a TV back cover processed by plastic suction. Background technique [0002] The current production process of the back cover of the household TV is generally sheet metal stamping or plastic injection molding. The plastic injection molding process accounts for more than 80%. The disadvantage of the injection molding process is that the injection mold is large, the mold opening time is long, and the mold cost is high. Under the market situation of rapid upgrading of home appliances, it cannot meet the requirements of rapid product development. Summary of the invention [0003] The present invention overcomes the shortcomings of the prior art and provides a low-cost plastic-blown TV rear cover molding process. [0004] Considering the above-mentioned problems of the prior art, according to one aspect of the present invention, the present ...
