The technical scheme adopted by the invention for solving the technical problems is that the toy manufacturing injection molding process comprises the following steps:

step S100, preparing materials, namely firstly mixing raw materials according to a formula, then placing the raw materials into a stirrer for stirring and mixing, then placing pigment into the stirrer for coloring the raw materials, and finally placing the mixed and colored raw materials into a dryer for baking and drying;

step S200, the plastic part is injection molded, a cleaning tool is used for cleaning a mold, the mold is blow-dried after cleaning, mold parameters are adjusted after impurity-free residues are determined, the dried raw materials are placed into the mold for mold shaping, and the mold is quickly cooled and naturally cooled after shaping;

Step S300, embedding a toy inlay, firstly carrying out nanocrystallization treatment on the surface of the inlay, then carrying out injection molding on nano plastic into a pit on the surface of the inlay through a nano injection molding process, integrating the plastic and aluminum alloy, and finally embedding the inlay into the plastic piece;

Step S400, injection molding of a finished product, namely, carrying out die assembly injection molding on the semi-finished product obtained in the step S300, integrating the insert and the plastic part, and carrying out quick cooling and natural cooling on the molded part;

Step S500, toy surface decoration, namely carrying out a water outlet removing process on the cooled plastic part, detecting the surface of the plastic part after water outlet removing, placing the plastic part with unqualified appearance into a collecting box, and polishing, cleaning and drying the plastic part with qualified appearance in the next process.

Preferably, the formula in the step S100 is prepared from the following raw materials in parts by weight:

30-50 parts of synthetic resin, 20-30 parts of filler, 5-10 parts of plasticizer, 5-10 parts of curing agent, 2-5 parts of reinforcing agent, 1-2 parts of preservative, 20-25 parts of epoxy resin, 1-2 parts of calcium carbonate powder, 1-3 parts of cross-linking agent and 1-2 parts of compatilizer.

Preferably, the material is prepared in step S100 in at least 3 parts, and the color of each part of raw material is not uniform.

Preferably, the die assembly injection molding in step S400 includes the steps of wrapping the plastic part and the insert with the molten material, and cooling the molten material in an intermittent cooling manner at a relatively low speed to prevent the occurrence of cracks.

Compared with the prior art, the invention has the beneficial effects that:

The plastic produced by the formula has very strong ductility, compression resistance and other performances, the mechanical strength is higher, the plastic particles are more condensed, and the plastic is formed by three times of injection molding, meanwhile, the raw materials and the colors are different, the raw materials for the first injection molding are hard rubber, the raw materials for the nanometer injection molding are also hard rubber, and the raw materials for the third injection molding are soft rubber, so that the produced toy has strong layering sense.
