[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0027] like Figures 1 to 5 As shown, in this embodiment, a manufacturing process of a large-sized solid toy includes the following steps:
[0028] S1. Prepare several molds, including but not limited to a first mold, a second mold, a third mold, a fourth mold, and a fifth mold;
[0029] S2. A first bone portion is designed in the first mold, and injection molding is performed in the first mold to obtain a first structure 1, wherein the first structure 1 includes a front frame 2 and an inner front bone portion 3;
[0030] S3. A second bone position is designed in the second mold. The first structure 1 is placed in the second mold for injection molding to obtain a second structure 4. The second structure 4 fills the front end of the front frame 2 and the rear side of the front bone position 3, and forms a middle bone position 5.
[0031] S4. A third bone position is designed in the third mold. The second structure 4 is placed in the third mold for injection molding to obtain a third structure 6. The third structure 6 covers the front end of the front frame 2, fills the rear side of the middle bone position 5, and forms the rear end bone position 7.
[0032] S5. A fourth bone position is designed in the fourth mold, and the third structure 6 is placed in the fourth mold for injection molding to obtain a fourth structure 8, wherein the fourth structure 8 covers the rear end bone position 7 and forms a covered bone position 9;
[0033] S6. Place the fourth structure 8 into the fifth mold for injection molding. During the injection molding process, the outer side of the fourth structure 8 is covered with rubber, wherein the covered rubber part is the fifth structure 10, and finally a finished product is obtained.
[0034] More specifically, the first bone position, the second bone position, the third bone position and the rear end bone position 7 are all horizontal bones parallel to each other. The outer side of the front frame 2 has a first expression structure, the front end of the second structure 4 has a second expression structure, and the front end of the third structure 6 has a third expression structure. The first expression structure, the second expression structure and the third expression structure form the expression of the finished product. A first connecting rod 11 is connected between the front end of the middle bone position 5 and the rear end of the middle bone position 5, and a second connecting rod 12 is connected between the front end of the rear end bone position 7 and the rear end of the rear end bone position 7. The inner side of the fifth structure 10 covers the first structure 1, the second structure 4, the third structure 6, and the fourth structure 8.
[0035] For large-sized solid toys, the fishbone glue-cutting method is used to form the bone structure, and the solid part inside the product is cross-divided into several parts to achieve an average material level for each color. The segmented injection molding reduces the cooling time of the injection molding.
[0036] For prominent isolated features such as the eyes and teeth of the toy, reverse injection molding is achieved from the inside out by opening holes in the half shell. That is, in the above description, the later molded structural part fills and covers the earlier molded structural part, subverting the problem of isolated feature injection molding that cannot be solved by traditional layer-by-layer stacking.
[0037] For special toy products that cannot be realized by normal multi-color encapsulation, they can be independently disassembled into multiple structures for assembly and injection molding to achieve different demoulding directions. In addition, injection molding of multiple different colors can solve more complex multi-color injection molding processes.
[0038] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be covered within the scope of protection of the present invention.
