Injection molding manufacturing method of upvc wall decoration board

Abstract

The invention discloses an injection molding manufacturing method of a UPVC wall decorative plate. The method comprises the following steps of opening a mold, arranging a film in the mold, wherein one surface of the film is an appearance display surface and the other surface of the film is a UPVC plastic layer, making the appearance display surface of the film contact with a molding surface of the mold and the UPVC plastic layer of the film face to the mold cavity space, positioning the sticky film in the mold by a film positioning device, closing the mold, injecting a molten UPVC material into the mold by a hot runner system through multiple branched channels and multiple plastic inlet points, keeping a closing state of the mold for a certain time until the molten UPVC material and the UPVC plastic layer are cured to form an integral wall decorative plate, opening the mold, and pushing the molded wall decorative plate out of the mold by a demolding device. The injection molding manufacturing method realizes large-scale and low-cost manufacture of the wall decorative plate from the UPVC material. The injection molding manufacturing method reduces a decorative material cost, shortens a finishing construction period, reduces a labor cost and realizes nontoxic gas discharge and environmental protection effects.

Description

technical field [0001] The invention relates to a wall decoration board, in particular to a manufacturing method of a UPVC wall decoration board. Background technique [0002] In the decoration industry, the materials used in traditional wall interior decoration are mainly cement, mortar, ceramic tiles or chemical coatings and adhesives. With the development of the times, this decoration method has exposed more and more problems, which can be attributed to the following aspects: 1. Due to the complicated construction, the consumption of man-hours is high, resulting in high labor costs; 2. 1. Due to the long time for material preparation and construction, the construction period is long, which will be difficult for occasions (such as shops) that require frequent changes in decoration style; 3. Because the above-mentioned traditional decoration does not fully consider environmental protection issues, it often contains harmful or Toxic substances (such as toxic gases such as p...

Problems solved by technology

With the development of the times, this decoration method has exposed more and more problems, which can be attributed to the following aspects: 1. Due to the complicated construction, the consumption of man-hours is high, resulting in high labor costs; 2. 1. Due to the long time for material preparation and construction, the construction period is long, which will be difficult for occasions (such as shops) that require frequent changes in decoration style; 3. Because the above-mentioned traditional decoration does not fully consider environmental protection issues, it often contains harmful or Toxic substances (such as toxic gases such as polyoxymethylene), thus causing harm to the human body

4. Decorative materials are easy to fall off (for example, wall tiles fall off) and fade easily

5. Maintenance and replacement are troublesome and time-consuming

6. When redecorating, 99% of the materials cannot be recycled and reused, resulting in great waste

7. The post-processing cost of decoration waste increases

But this document also does not disclose any scheme about mounting on the mount

In addition, this composite multi-layer material cannot be recycled conveniently, and the manufacturing process is complicated
