Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a toy injection mold. Background Technology

[0002] Children's toys refer to items specifically designed for children's play. Toys are the backbone through which children translate their imagination, thinking, and other psychological processes into behavior. Children's toys can develop motor skills, train perception, stimulate imagination, arouse curiosity, and provide material conditions for children's physical and mental development. The main types of children's toys include: figurative toys, technical toys, assembly and building toys, construction and structural toys, sports activity toys, musical and sound-producing toys, labor activity toys, decorative toys, and homemade toys. The general educational requirements for toys are: they should promote the all-round development of children's physical, moral, intellectual, and aesthetic qualities; they should conform to children's age characteristics; they should satisfy their curiosity, activity, and desire for exploration; they should have beautiful shapes that reflect the typical characteristics of things; they should have varied activities that help encourage learning; they should meet hygiene requirements; they should be non-toxic in color; they should be easy to clean and disinfect; and they should meet safety requirements.

[0003] Existing injection molding molds require an injection tube to be inserted into the mold's filling hole during injection. During injection, the slurry forms a column in the filling hole, which needs to be processed after the mold is formed. This results in redundant steps, thus requiring a toy injection mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a toy injection mold, employing the following technical solution: It includes a base plate, with support plates fixedly mounted at both ends. Multiple lower frames are spaced apart on the base plate. Each support plate is equipped with a lifting device, and positioning plates are positioned between the lifting devices. Multiple upper frames, adapted to the lower frames, are spaced apart on the positioning plates. Each upper frame has an upper toy cavity with a filling hole at its upper end. Each lower frame has a lower toy cavity, and the upper end of each upper frame is equipped with a sealing mechanism for sealing the filling hole.

[0005] Furthermore, the lifting device includes a motor installed in the support plate, the output end of the motor is connected to a lead screw, the lead screw is threadedly connected to a support block, the support block is fixedly connected to the upper frame, and a guide rod is fixedly installed on one side of the support plate located on the lead screw, with the support block sleeved on the guide rod.

[0006] Furthermore, the motor is a servo motor.

[0007] Furthermore, the sealing mechanism includes positioning grooves on both sides of the filling hole at the upper end of the upper frame. One end of a spring is fixedly connected to the inner wall of the positioning groove, and the other end of the spring is fixedly connected to a sealing block. The upper end of the sealing block is a wedge shape that slopes from the side to the center, and the lower end of the sealing block has a curved surface that fits into the upper toy mold cavity.

[0008] Furthermore, the sealing block is made of plastic.

[0009] Beneficial effects

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The injection mold of this utility model is equipped with a sealing mechanism. When the injection tube extends into the filling hole of the mold for injection, the injection tube can push open the sealing block to carry out injection. After the injection is completed, when the injection tube extends out of the filling hole, excess slurry will remain in the filling hole. After the sealing block of the sealing mechanism closes, the excess slurry will be squeezed out, thereby avoiding the formation of excess slurry in the filling hole. Attached Figure Description

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] Reference Figures 1-3According to an embodiment of the present invention, a toy injection mold includes a base plate 1, with support plates 2 fixedly disposed at both ends of the base plate 1. Multiple lower frame bodies 3 are spaced apart on the base plate 1. Each support plate 2 is equipped with a lifting device, and a positioning plate 4 is disposed between the lifting devices. Multiple upper frame bodies 5, adapted to the lower frame bodies 3, are spaced apart on the positioning plate 4. Each upper frame body 5 has an upper toy cavity 6, and a filling hole 15 is provided at its upper end. Each lower frame body 3 has a lower toy cavity 7. A sealing mechanism for sealing the filling hole 15 is provided at the upper end of each upper frame body 5. The lifting devices drive the support plates 2 and positioning plates 4 to rise and fall, thereby allowing the upper frame bodies 5 to be joined with the corresponding lower frame bodies 3 to form a complete toy cavity. Injection is then performed through an injection tube inserted into the filling hole 15. When injection is complete, excess slurry may remain in the filling hole 15. The sealing mechanism can squeeze out the excess slurry to prevent residue.

[0019] Furthermore, the lifting device includes a motor 8 installed in the support plate 2, the output end of the motor 8 is connected to a lead screw 9, the lead screw 9 is threadedly connected to a support block 11, the support block 11 is fixedly connected to the upper frame 5, a guide rod 10 is fixedly installed on one side of the support plate 2 located on the lead screw 9, and the support block 11 is sleeved on the guide rod 10. The motor 8 is a servo motor 8; the motor 8 drives the lead screw 9 to rotate, so that the support block 11 moves up and down, and the upper frame 5 between the support blocks 11 can move with the movement of the support blocks 11, and the guide rod 10 can provide stability for the support blocks 11.

[0020] Furthermore, the sealing mechanism includes positioning grooves 12 on both sides of the filling hole 15 at the upper end of the upper frame 5. One end of a spring 13 is fixedly connected to the inner wall of the positioning groove 12, and the other end of the spring 13 is fixedly connected to a sealing block 14. The upper end of the sealing block 14 is a wedge shape that slopes from the side to the center, and the lower end of the sealing block 14 has a curved surface that fits against the upper toy mold cavity 6. The sealing block 14 is made of plastic. During injection molding, the injection tube extends into the filling hole 15, abuts against the upper end of the sealing block 14 and pushes it open. The sealing block 14 then compresses the spring 13. The injection tube extends into the upper toy mold cavity 6 for injection molding. After injection molding, the slurry is likely to leave residue in the filling hole 15. When the injection tube extends into the filling hole 15, the sealing block 14, pushed by the spring 13, will squeeze out the residual slurry and prevent the molded model from having residue.

[0021] In specific operation, the motor 8 drives the lead screw 9 to rotate, thereby causing the support block 11 and the upper frame 5 to move downwards. The upper frame 5 and the lower frame 3 merge together, and the upper toy mold cavity 6 and the lower toy mold cavity 7 form a complete toy model cavity. Then, the injection tube extends into the filling hole 15, abuts against the upper end of the sealing block 14 and pushes it open. The sealing block 14 then compresses the spring 13. The injection tube extends into the upper toy mold cavity 6 for injection molding. After injection molding, the slurry is prone to leave residue in the filling hole 15. When the injection tube extends into the filling hole 15, the sealing block 14, pushed by the spring 13, will squeeze out the residual slurry and prevent the molded model from having residue.
