[0002] Injection molding is also called injection molding. It is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise production dimensions. Products are easy to update and can form parts with complex shapes. Injection molding is suitable for mass production and molding and processing fields such as products with complex shapes.

[0003] A method in which completely molten plastic material is stirred by a screw at a certain temperature, injected into a mold cavity with high pressure, and then cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods.

[0004] However, the traditional toy manufacturing injection molding process is not reasonable enough, and to a certain extent it is easy to cause unqualified product quality or failure to meet standards, waste resources and labor, such as insufficient melting of raw materials, easy deformation of products during cooling, etc. Therefore, it is urgent to design a toy manufacturing injection molding process that can meet people's needs.

[0008] Step S200, injection molding plastic parts, using a cleaning tool to clean the mold, blow it dry after cleaning, and adjust the mold parameters after confirming that there are no impurities left, then put the dried raw materials into the mold for mold shaping, and after the mold is shaped, quickly cool it and cool it naturally;

[0009] Step S300, inlaying the toy inlay, firstly performing nano-treatment on the surface of the inlay, then injecting nano plastic into the pit on the surface of the inlay by nano injection molding process, so that the plastic and the aluminum alloy are integrated, and finally embedding the inlay into the interior of the plastic part;

[0010] Step S400, finished product injection molding, the semi-finished product obtained in step S300 is molded and injection molded to integrate the insert and the plastic part, and the mold is quickly cooled and naturally cooled after being finalized;

[0011] Step S500, toy surface decoration, the cooled plastic parts are subjected to a draining process, and the surface of the plastic parts after the draining process is inspected, and the plastic parts with unqualified appearance are placed in a collection box, while the plastic parts with qualified appearance flow into the next process for polishing, cleaning and drying.

[0015] Preferably, the mold closing and injection molding in step S400 includes the following steps: the molten material wraps around the plastic part and the inlay, and an intermittent cooling method is used to make the cooling speed of the molten material relatively slow to prevent the generation of cracks.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The plastic produced by this formula has strong ductility, compression resistance and other properties, high mechanical strength, more condensed plastic particles, and is molded through three injection moldings. At the same time, the raw materials and colors are different. The raw material for the first injection molding is hard glue, and the nano injection molding is also hard glue. The raw material for the third injection molding is soft glue. Therefore, the toys produced have a strong sense of layering. BRIEF DESCRIPTION OF THE DRAWINGS
