DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 1 to Figure 8As shown, a nozzle deformation prevention replacement and disassembly mechanism for toy preparation includes a joint 1 applied to the discharge part of the injection molding machine and a clamping plate 6 for fixing the injection mold. The joint 1 includes a thermal insulation layer 2 for ensuring the injection temperature, a step frame 3 for resisting deformation, a nozzle 4 for easy disassembly and a ring frame 5 for reducing the rigid wear of the nozzle 4. The joint 1 is an annular structure with a cavity. The clamping plate 6 is engaged with one end of the joint 1. The thermal insulation layer 2 has a cavity structure and is arranged on the top of the joint 1. The step frame 3 is installed on the top of the thermal insulation layer 2. The nozzle 4 is arranged at the center of the step frame 3. The ring frame 5 is arranged at the bottom of the nozzle 4 and is in the thermal insulation layer 2.

[0028] The disassembly mechanism connects the discharge part of the injection molding machine and the card plate 6 through a rotating joint 1, and injection molding is performed through a mold pre-set on the card plate 6. During the rotation process, the step frame 3 fits tightly with the card plate 6 to prevent leakage of molten raw materials while ensuring uniform force between the nozzle 4 and the card plate 6 to resist deformation. The ring frame 5 is used to facilitate the installation and disassembly of the nozzle 4 and provide a certain amount of movement margin for the nozzle 4, so that the wear of the nozzle 4 caused by the injection pressure can be reduced in the insulation layer 2 during the injection molding process. The insulation layer 2 is easy to disassemble from the joint 1 while ensuring the injection temperature, which further facilitates the replacement and maintenance of the nozzle 4.

[0029] See also Figure 1~Figure 4 As shown, the insulation layer 2 includes a positioning hole 21, an engaging groove 22 and a threaded interface 23. The positioning hole 21 is arranged at the top of the insulation layer 2 and passes through the step frame 3. The engaging groove 22 is arranged in a circular array in the positioning hole 21. The threaded interface 23 is arranged at the connection between the insulation layer 2 and the joint 1.

[0030] The positioning hole 21 is used to position the nozzle 4, and the engaging groove 22 is used to fix the nozzle 4. When the joint 1 is docked with the card plate 6, the insulation layer 2 is required to drive the nozzle 4 to rotate to ensure that the joint 1 and the card plate 6 are seamlessly fitted. When the nozzle 4 needs to be replaced urgently, the joint 1 and the insulation layer 2 are separated by the threaded interface 23 to avoid stopping the injection molding work in order to withdraw the joint 1.

[0031] See also Figure 3~Figure 5 As shown, the step frame 3 includes a thread groove 31 , a clamping frame 32 and a feeding port 33 . The thread groove 31 is arranged on the arc surface of the step frame 3 . The clamping frame 32 is embedded and installed with the step frame 3 . The feeding port 33 is arranged at the center of the clamping frame 32 .

[0032] The clamping frame 32 is rotatably fitted with the step frame 3, and the close fit between the two improves the deformation resistance of the joint 1 and avoids the possibility of deformation of the joint 1 under high temperature conditions. The feed port 33 is connected to the mold interface on the clamping plate 6, and is used for the nozzle 4 to deliver molten raw materials for injection molding.

[0033] See also Figure 3~Figure 6As shown, the nozzle 4 includes a cutting blade 41 , a clamping strip 42 and a discharge hole 43 . The cutting blade 41 is arranged on the arc surface of the nozzle 4 , the clamping strip 42 is arranged in an array at the bottom of the nozzle 4 , and the discharge hole 43 is arranged on the nozzle 4 .

[0034] The cutting blade 41 is used to facilitate the detachment of the nozzle 4. After the injection molding is finalized and cooled, the nozzle 4 is easy to adhere to the product. The nozzle 4 is driven to detach from the clamping plate 6 through the reverse rotating joint 1. At this time, the cutting blade 41 cuts the material surrounding the nozzle 4 into pieces, making it easy to remove the nozzle 4.

[0035] See also Figure 6 As shown, the ring frame 5 includes a pressurized pipe 51 and a positioning rod 52 . The pressurized pipe 51 is arranged at the bottom of the nozzle 4 . The positioning rod 52 passes through the ring frame 5 and is connected to the lower surface of the step frame 3 .

[0036] The diameter of the pressurized pipe 51 is larger than the diameter of the nozzle 4 , and the diameter narrows from wide to narrow so as to provide pressure for the nozzle 4 to transport raw materials. The positioning rod 52 is used to fix the nozzle 4 and provide guidance for the movement of the nozzle 4 .

[0037] See also Figure 5 and Figure 6 As shown, the positioning rod 52 includes a gasket 521 and a spring 522. The gasket 521 is arranged on both sides of the ring frame 5. One end of the spring 522 is connected to the lower surface of the ladder frame 3, and the other end is connected to one side of the gasket 521.

[0038] The gasket 521 is used to clamp the ring frame 5, and the spring 522 provides a reset capability for the movement of the nozzle 4. When the injection pressure is too high, the nozzle 4 moves along the direction of the positioning rod 52 to reduce pressure and avoid excessive pressure from damaging parts. When the injection pressure is balanced, the spring 522 drives the nozzle 4 to reset.

[0039] See also Figure 1 to Figure 7 As shown, the card plate 6 includes a water pipe 61, a telescopic rod 62 and a mounting hole 63. The water pipe 61 is arranged inside the card plate 6, the telescopic rod 62 is installed at four ends of one side of the card plate 6, and the mounting hole 63 is arranged on the surface of the card plate 6 on the same side as the telescopic rod 62.

[0040] The water pipe 61 is used to provide a cooling path for the unformed product, the telescopic rod 62 is used to control the production and shedding of the product, and the mounting hole 63 is used to install a preset mold and facilitate the replacement of the mold.

[0041] See also Figure 1 to Figure 8As shown, an injection molding machine includes a laminating plate 7, a feeding tube 8 and the above-mentioned anti-deformation replacement and disassembly mechanism for the nozzle for toy preparation, the laminating plate 7 includes a seal 71, an air hole 72 and a push rod 73, the laminating plate 7 is installed on the telescopic rod 62 and is respectively located at the two ends of the telescopic rod 62 with the clamping plate 6, the feeding tube 8 is connected to the bottom of the ring frame 5, the seal 71 is arranged at the center of the laminating plate 7, the air hole 72 is arranged on the seal 71, and the push rod 73 passes through the laminating plate 7 and is located in the seal 71.

[0042] When the laminating plate 7 is in close contact with the cardboard 6, the molten raw material is fed into the mold from the feeding pipe 8 for molding. When molding is completed, the laminating plate 7 is pulled away from the cardboard 6 along the telescopic rod 62. At this time, the product is stuck at the seal 71. The product is pushed down from the seal 71 by the push rod 73 for the next injection molding. The air hole 72 is used to balance the air pressure to facilitate the detachment of the product.

[0043] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
