Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing, specifically a heating device for plastic product manufacturing. Background Technology

[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This includes products manufactured using processes such as injection molding and vacuum forming. The production of plastic products requires specialized equipment, such as injection molding machines and vacuum forming machines.

[0003] In existing injection molding machines, raw materials are conveyed into the material tube by a feeding mechanism. The material tube is heated by heating rings installed on its surface to melt the raw materials. The molten raw materials are then injected into the designated mold through the injection nozzle for molding. The heating rings on the surface of the material tube of existing injection molding machines consist of two sets of semi-circular heating rings fitted onto the surface of the material tube, and the two sets of semi-circular heating rings are connected together by bolts.

[0004] However, injection molding machines generate vibrations during operation. Prolonged vibrations can cause the connecting bolts of the heating ring to loosen, resulting in a loose fit between the heating ring and the material tube, which reduces the heating effect and affects the normal operation of the injection molding machine. Furthermore, the connecting bolts of the heating ring are generally quite long, requiring too many turns when replacing the heating ring, which affects work efficiency. Therefore, this utility model proposes a heating device for plastic product manufacturing to solve the above-mentioned technical problems. Utility Model Content

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a heating device for producing plastic products, the heating device for producing plastic products includes: a material pipe 1, and a positioning groove 2 is formed on the surface of the material pipe 1;

[0023] Heating ring 3, a base plate 4 is provided on the surface of heating ring 3, a lifting rod 5 is provided inside the base plate 4, a lifting plate 6 is sleeved on the surface of the lifting rod 5, a support plate 7 is provided on the side of the lifting plate 6, a limit rod 8 is provided on the side of the support plate 7, a limit plate 9 is provided on the surface of the lifting plate 6, and a positioning groove 10 is provided on the surface of the base plate 4.

[0024] First, by pulling the lifting plate 6, the fixing plate 14 can be inserted into the positioning groove 10, thereby allowing the two sets of heating rings 3 to cooperate and be fixed on the surface of the material tube 1. Then, the limiting rod 8 is inserted into the positioning groove 2 to prevent the heating rings 3 from sliding on the surface of the material tube 1. When it is necessary to replace the heating rings 3, the lifting plate 6 can be pulled directly to remove the fixing plate 14 from the positioning groove 10, and the limiting rod 8 can be removed from the positioning groove 2. Then, the two sets of heating rings 3 can be removed from the material tube 1.

[0025] Example 2: Based on Example 1, in order to facilitate the fixing of the heating ring 3 to the material tube 1, a lifting plate 6 is provided. The bottom plate 4 is fixedly connected to the surface of the heating ring 3. The heating ring 3 has an arc-shaped plate structure. After the two sets of heating rings 3 are aligned, they are fitted into a circular ring shape on the material tube 1. The bottom plate 4 has a lifting groove 11 on its surface and a moving groove 12 on its side. The lifting rod 5 is fixedly connected to the surface of the lifting groove 11. A limiting spring 15 is fitted on the surface of the lifting rod 5. The lifting plate 6 can move up and down along the lifting rod 5. The support plate 7 can move up and down in the moving groove 12. The support plate 7 has a square plate structure.

[0026] When in use, first pull up the lifting plate 6 to move the fixing plate 14 upward, then the two sets of heating rings 3 can be fitted onto the material tube 1. Then the lifting plate 6 can be loosened so that one end of the fixing plate 14 can be easily inserted into the positioning groove 10, thereby fixing the two sets of heating rings 3 onto the material tube 1.

[0027] Example 3: Based on Example 2, in order to increase the stability of the heating ring 3 on the material tube 1, a limiting rod 8 is provided. Multiple sets of positioning slots 2 are provided, and the multiple sets of positioning slots 2 are linearly arranged at equal intervals about the surface of the material tube 1. One end of the limiting rod 8 can be inserted into the positioning slot 2. The surface of the lifting rod 5 is threaded, and a limiting nut 13 is screwed onto the thread. One end of the limiting spring 15 is fixedly connected to the surface of the limiting nut 13, and the other end of the limiting spring 15 abuts against the surface of the lifting plate 6. The limiting plate 9 is fixedly connected to the surface of the lifting plate 6. A fixing plate 14 is provided on the side of the limiting plate 9. One end of the fixing plate 14 can be inserted into the positioning groove 10. The fixing plate 14 has a square plate structure.

[0028] When in use, the fixing plate 14 is inserted into the positioning groove 10, so that one end of the limiting rod 8 is inserted into the positioning groove 2. The limiting rod 8 is inserted into the positioning groove 2 to prevent the heating ring 3 from sliding on the material tube 1. The setting of the limiting spring 15 can facilitate the lifting plate 6 to be reset by the elastic force of the limiting spring 15 after the lifting plate 6 is pulled. The downward pressure of the limiting spring 15 can also fix the lifting plate 6 to prevent random displacement. When it is necessary to remove the lifting plate 6, the limiting nut 13 can be rotated to disengage the limiting nut 13 from the lifting rod 5, and the lifting plate 6 can be removed.
