Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a mold structure that facilitates rapid adjustment of the structure of injection molded products, including a left mold 1, a right mold 2 corresponding to one side of the left mold 1, and the left mold 1 and the right mold 2 are respectively inserted into guide pillars. The left mold 1 has an installation groove, and an installation frame 3 is placed in the installation groove. The installation frame 3 has a mold groove, and a mold block is correspondingly provided on the right mold 2. The installation frame 3 has first bolts 4 screwed on four sides, and the other end of the first bolts 4 is screwed into the left mold 1.

[0021] Furthermore, the mounting bracket 3 forms a spiral locking structure with the left mold 1 within the mounting groove by multiple sets of first bolts 4, thereby increasing the convenience of the device to adjust the shape of the required injection molded product by replacing the mounting bracket 3.

[0022] The right mold 2 is provided with a feed pipe 5 on the right side, and the lower end of the feed pipe 5 is connected to the feed hopper 6. The lower end of the feed hopper 6 is connected to the conveying pipe 7, and the conveying pipe 7 is provided with a motor 8 at one end. One end of the output shaft of the motor 8 is connected to the injection screw 9 through a coupling. The conveying pipe 7 is provided with a fixing pipe 10 at the left end, and the fixing pipe 10 is spirally provided with a nozzle 11. The conveying pipe 7 is provided with a heating plate 20 on the outer wall, and one side of the heating plate 20 is covered with a heat insulation plate 21 on the outside of the conveying pipe 7. A temperature detector 22 is inserted through the heat insulation plate 21.

[0023] Furthermore, under the action of the motor 8, the injection screw 9 forms a rotating structure in the material delivery pipe 7 through the output shaft and coupling, thereby driving the injection screw 9 to rotate through the motor 8, so that the rotating injection screw 9 pushes the material into the mold groove for injection molding.

[0024] Furthermore, the outer wall of one end of the nozzle 11 and the inner wall of the fixing tube 10 are respectively provided with matching threads, and the nozzle 11 forms a spiral locking structure with the material delivery tube 7 through the fixing tube 10, so as to facilitate the selection of the nozzle 11 with the corresponding opening size according to the shape and size of the mold to be injected for injection molding.

[0025] The feed pipe 7 is equipped with a fixed frame 12 at the top, and a servo motor 13 is installed inside the fixed frame 12. One end of the output shaft of the servo motor 13 is connected to the screw 14 through a coupling, and a sliding rod 15 is provided on one side of the screw 14. A movable block 16 is inserted through the screw 14 and the sliding rod 15, and a connecting rod 17 is provided at the lower end of the movable block 16. The lower end of the connecting rod 17 is inserted into the sliding groove on the fixed rod 19, and a second bolt 18 is inserted through the connecting rod 17 and the fixed rod 19. It should be noted that this utility model is a mold structure that facilitates rapid adjustment of the structure of injection molded products. All components are standard parts or components known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In this device, all the above-mentioned electrical components refer to power components, electrical components, and the matching monitoring computer and power supply connected by wires. The specific connection method should refer to the working principle above, and the electrical connection between each electrical component is completed in sequence. The detailed connection method is a well-known technology in the field.

[0026] Furthermore, under the action of the servo motor 13, the connecting rod 17 forms a limiting sliding structure with the fixed frame 12 through the screw 14, slide rod 15, movable block 16, and the connecting rod 17 forms a spiral locking structure with the fixed rod 19 through the second bolt 18. Thus, the servo motor 13 drives the material conveying pipe 7 to slide in a limiting manner, so as to adjust the position of the material conveying pipe 7 and the injection nozzle 11 according to the position of the injection hole on the right mold 2.

[0027] Working Principle: Using a mold structure that facilitates rapid adjustment of the injection molded product structure, the temperature of the heating tubes within the heating plate 20 can be adjusted via the control panel on the heating plate 20. This allows for easy control of the temperature inside the material delivery pipe 7 according to the injection molding process, ensuring energy efficiency while effectively guaranteeing the heat-melting effect of the material inside the material delivery pipe 7. Simultaneously, the temperature at the other end of the material delivery pipe 7 can be monitored via the temperature detector 22 on the insulation plate 21, ensuring the accuracy of the temperature monitoring data and thus the precision of temperature adjustment. During the use of the material delivery pipe 7, material can be fed into it through the feed pipe 5 and feed hopper 6. Simultaneously, the motor 8 can be started, and one end of the output shaft of the motor 8 drives the injection screw 9 to rotate via a coupling. The rotating injection screw pushes the molten material into the screw for injection molding. If the product injection shape needs to be adjusted during the use of the injection mold, the right mold 2 can be disassembled and replaced, and the first bolt 4 can be removed via a screw to select the appropriate shape based on the mold block on the right mold 2. The mounting bracket 3 of the mold slot is installed, and then the corresponding mounting bracket 3 can be installed through the first bolt 4 to increase the convenience of replacing the entire injection mold. Then, the position of the nozzle 11 can be adjusted according to the position of the injection hole on the right mold 2. After removing the second bolt 18 by screwing, the material delivery pipe 7 can be displaced as a whole, so that the screw 14 can be rotated by the servo motor 13, and the rotating screw 14 can drive the movable block 16 to move. At the same time, the movable block 16 is limited by the sliding rod 15, so that the material delivery pipe 7 can be moved horizontally by the movable block 16 that is limited to slide. After the material delivery pipe 7 moves to the appropriate position, the nozzle 11 is slid into the injection hole again by the sliding connecting rod 17, so as to ensure that the device can perform injection molding normally. At the same time, the nozzle 11 can be screwed to replace according to the shape and size of the mold, so that the material can be fully filled into the mold slot by the nozzle 11 with the appropriate hole size, further increasing the convenience of the device for adjusting the shape of the injection molded product. This is the usage process of the mold structure that facilitates the rapid adjustment of the injection molded product structure.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
