Problems solved by technology

[0002] The injection molding control panel in the prior art is usually made of non-environmental-friendly materials, and the size and overall thickness are too large, which increases the weight of the product and further leads to technical problems such as high production cost and inconvenient transportation and carrying.
In addition, because the material of the injection molding control panel in the prior art is usually polyvinyl chloride, its insulation is relatively weak, and the mold takes a long time in molding and cooling, and the mold used is not equipped with a water cooling system, resulting in injection molded products. The shrinkage ratio is too large, and the yield is low
There are many defects in the product: insufficient aging resistance, flammability, limited application in industrial occasions that withstand impact or load structures

Abstract

The invention discloses an injection molded control panel. The control panel is prepared from, by weight, 45-55 parts of PC resin flakes, 7-11 parts of panel filler, 5-8 parts of powdered metal and 1-2 parts of a light conversion agent. The invention further discloses an injection molding process of the injection molded control panel. The injection molding process comprises the steps of raw material pretreatment, material mixing, material drying, pretreatment through an injection molding system and an injection mold, injection molding, pressure maintaining, mold disassembling and the like. ThePC resin flakes are selected and used as main materials for replacing polyvinyl chloride in the prior art, thus, the manufactured injection molded control panel has high strength and elastic coefficient and good insulation performance; meanwhile, by adding the panel filler comprising calcium silicate, magnesium carbonate, diatom ooze and glass fibers into the raw materials, the abrasion resistance and the fatigue resistance of the control panel can be improved; and the injection molding process is easy and convenient to operate and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of injection molding control panel manufacturing, and in particular relates to an injection molding control panel and an injection molding process thereof. Background technique [0002] The injection molding control panel in the prior art is usually made of non-environmental-friendly materials, and the size and overall thickness are too large, which increases the weight of the product and further leads to technical problems such as high production cost and inconvenient transportation. In addition, because the material of the injection molding control panel in the prior art is usually polyvinyl chloride, its insulation is relatively weak, and the mold takes a long time in molding and cooling, and the mold used is not equipped with a water cooling system, resulting in injection molded products. If the shrinkage ratio is too large, the yield is low. There are many defects in the products: insufficient aging re...
