Problems solved by technology

[0002] With the improvement of people's living standards, people put forward higher requirements for the appearance of household appliances, and pay more and more attention to the aesthetic effect of household appliances. As we all know, an important aspect that affects the appearance of household appliances is the shell of household appliances, such as for flat panel display products As far as the current popular flat-panel display product shell is injection molded from two transparent materials, the injection molding process generally adopts two-color injection molding method. However, the mold development cost of two-color injection molding is very expensive, and special two-color injection molding equipment is required. The positioning accuracy requirements in the injection molding process are particularly high
Due to its high technical threshold, large capital demand, and high production costs, most domestic companies dare not easily invest in product development, resulting in a gap between the market competitiveness of domestic flat-panel TV casings and foreign brands.
[0003] Therefore, manufacturers or supporting manufacturers of household appliances, especially domestic manufacturers, still face difficulties in improving the appearance of household appliances and reducing costs

Embodiment Construction

[0020] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0021] Such as figure 1 As shown, a casing of a household appliance, the casing includes a first layer 1 of the casing and a second layer 2 of the casing, wherein the first layer 1 of the casing is a transparent layer, the second layer 2 of the casing is a translucent layer, and the casing The first layer 1 and the second layer 2 of the casing are successively solidified and integrally injection molded. In this embodiment, the first layer 1 of the casing is the outer layer, and the second layer 2 of the casing is the inner layer.

[0022] The injection molding method of the foregoing shell comprises the steps:

[0023] A. Inject the first layer 1 of the shell in the first set of molds; B. Take out the first layer 1 of the shell from the first set of molds and put it into the cavity of the second set of molds; C. The second shell layer 2 is injected into the...
