Problems solved by technology
[0002] At present, in related technologies, high-speed injection molding machines are generally used for injection molding of thin-walled plastic parts, but the injection cost of high-speed injection molding machines is 6-8 times that of ordinary injection molding machines, which seriously increases the production cost of products. Ordinary injection molding machine for injection molding will reduce fluidity due to high cavity pressure, making the molding of plastic parts unstable, and there will be too many burrs when using ordinary injection molding machines, which seriously affects the appearance quality of products, and the quality of plastic parts Weld marks are not easy to solve, which reduces the overall strength of plastic parts

The invention provides a glue feeding mode and ranking optimization method and an injection molding method. The glue feeding mode and ranking optimization method comprises the following steps: (102) an upper cover is optimized; a sprue of the upper cover is set as a two-point sprue; a glue feeding mode is set as side glue feeding; and a runner is set to convert from an open hot runner to a cold runner; (104) a middle cover is optimized; a sprue of the middle cover is set as a two-point sprue; the glue feeding mode is set as non-appearance surface point glue feeding; and the runner is set as a forward needle valve hot runner; and (106) a lower cover is optimized; a sprue of the lower cover is set as a one-point submersible sprue; the glue feeding mode is set as side glue feeding; and the runner is set as the forward needle valve hot runner. Through the settings, the injection molding of the upper cover, the middle cover and the lower cover by a general injection molding machine is realized, and the injection molding cost is effectively reduced; and through optimization of the sprue position and the glue feeding mode, the problem of weld lines can be effectively solved, the overall workpiece strength is guaranteed, and the beauty is higher.
