Injection molding process of plastic basin

Abstract

The invention discloses an injection molding process of a plastic basin. The process comprises the following raw materials in parts by weight: 32 parts of polyester chips, 5 parts of amino resin, 3 parts of butadiene, 3-4 parts of lignin, 1 part of methyl cellulose, 11 parts of polyvinyl alcohol, 9 parts of glacial acetic acid and 7 parts of benzoic acid. An injection molding preparation is carried out by sequentially placing the polyester chips, the amino resin, the butadiene, the lignin and the methyl cellulose into a stirring cylinder to be stirred, and a reinforcing agent is added during stirring. According to the injection molding process of the plastic basin, firstly, hardness of a finished product formed by injection molding is higher, the finished product is not easily broken, theservice life of the plastic basin is prolonged, and gas with peculiar smell or toxicity is not generated in the preparation process; and secondly, integrity of injection molding and uniformity of internal materials of the finished product can be improved, hardness of the finished product is further improved at the same time, and impact hardness, stretching strength and the tensile strength of theplastic basin can be improved, so that a better application prospect is achieved.

Description

technical field [0001] The invention relates to the field of injection molding technology, in particular to an injection molding technology for plastic pots. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method. Plastic basins also need to use injection molding devices to inject melted plastic into the plastic basin. In the mold, extruded through the mold; [0003] There are certain disadvantages in the existing injection molding process of plastic basins. When the existing plastic basins are injected, the thickness of the plastic basins is relatively thin, so the distance between the corresponding movable mold and the fixed mold is also small. At the same time, because the hot-melt plastic itself has less fluidity and is relatively viscous, it is difficult for...

Problems solved by technology

[0003] There are certain disadvantages in the existing injection molding process of plastic basins. When the existing plastic basins are injected, the thickness of the plastic basins is relatively thin, so the distance between the corresponding movable mold and the fixed mold is also small. At the same time, because the hot-melt plastic itself has less fluidity and is relatively viscous, it is difficult for the hot-melt plastic to enter these narrow spaces. The contact area with the inner wall of the mold increases, and the heat dissipation is faster, which causes the surface of the hot melt plastic to solidify and affects the flow of the plastic. Moreover, the existing plastic pot injection molding raw materials will produce odor and toxic gas when burned. , affecting the processing environment and the health of the staff, for this reason, we propose an injection molding process for plastic basins
