IML reverse covering process of laundry machine panel

Abstract

The invention discloses an IML reverse covering process of a laundry machine panel. The process comprises the following steps: discharging a PET film, and cutting the PET film into a PET sheet of the corresponding size according to product appearance; printing the PET sheet, namely printing patterns on the PET sheet through a screen printing machine; thermally forming the PET sheet, namely performing thermal forming on the printed PET sheet through a thermal forming machine; inlaying the PET sheet, namely placing the thermally formed PET sheet to a movable mold cavity of an injection molding mold, wherein the printing surface of the PET sheet faces downwards and is positioned; performing product injection molding, namely performing injection molding on the product by using a two-plate mold, and fusing the PET sheet to the surface of a plastic piece through high-temperature high-pressure injection molding; opening the mold and taking out the finished product; and packaging. The process has the advantages that the production cycle is shortened, the waste of remnants is reduced, and the quality of the product is ensured.

Description

technical field [0001] The invention relates to an IML reverse-wrapping process for a washing machine panel. Background technique [0002] The traditional IML technology for washing machine panels only connects the decorative film belly to the front mold of the injection mold, and there are leaks of various sizes on the analysis surface that affect the overall aesthetics of the product. The innovative product wraps the decorative film back to the parting position. The rear mold area ensures zero leakage of the product and improves the overall quality of the product. [0003] Such as figure 1 As shown, in the current washing machine panel IML reverse-wrapping technology, the product is usually injected with a three-plate mold for injection molding. The disadvantages of traditional reverse-wrapping are: [0004] 1. The production cycle is long; [0005] 2. The surface of the sheet in the rubber sealing area of ​​the slider is easy to scratch; [0006] 3. The longer the ma...

AI Technical Summary

Problems solved by technology

[0004] 1. The production cycle is long;

[0005] 2. The surface of the sheet in the rubber sealing area of ​​the slider is easy to scratch;

[0006] 3. The longer the material head, the more waste is wasted;

[0007] 4. The longer material head leads to greater pressure loss in injection molding, and it is difficult to guarantee the appearance of the product;

[0008] 5. The mold structure is complex, and the slider is easy to run away from the repeated working position;

[0009] 6. The cost of mold development is high
