A mold that can improve the yield of TV casings

Abstract

The invention discloses a mould capable of improving the yield of television shells. The mould comprises a hot melting mechanism for melting raw materials into a liquid, wherein the hot melting mechanism is connected with an injection gun by a pipeline; the jet orifice of the injection gun is connected with a television shell forming mould; and hydrogen gas inletsareformed in thepipeline. According to the mould, moisture in the raw material can be removed by hydrogen gas, and the yield and the speed can be improved; by virtue of an extremely simple chamber structure, multi-time contact between a raw material solution and the hydrogen gas can be realized, so that the quality of the formed product can be greatly improved; stirring mechanisms or spraying mechanismsarearranged in thepipeline or hydrogen cavities, or the pipeline is arranged into a U-shaped pipeline or a curve type pipeline; in large-scale production,when the adopted pipeline is relatively large in diameter, the contact area between the raw material solution and the hydrogen gas can be increasedby virtue of stirring, spraying, the U shape or the curve shape; and the flow velocity and the compactness of the solution in the pipeline can be regulated by a reducing pipe structure, and the yield of the television shells can be improved. The mould is simple in structure and very practical.

Description

technical field [0001] The invention relates to the manufacturing equipment of the TV casing, in particular to a mold which can improve the yield of the TV casing. Background technique [0002] TV casings are mainly mass-produced through molds, and their structure includes a hot-melt mechanism for melting raw materials into liquids. The hot-melt mechanism is connected to an injection gun through a pipeline (injection gun: used to inject the melted raw material into the molding mold inside, similar to the principle of a glue gun, which can provide uniformity of solution injection and avoid air bubbles), the injection port of the injection gun is connected to the TV casing molding mold. In the prior art, due to the presence of more water in the solution, it will affect the TV. The yield and speed of the finished product of the casing. [0003] On the other hand, since the solution is mainly melted from granular raw materials, the granular raw materials are not only inhomogene...
