[0002] A paper guide wheel is a wheel used to guide and position materials such as conveyor belts or paper. It is commonly used in various automated systems and mechanical equipment to ensure that materials maintain the correct position and direction during transmission or processing. The design of the paper guide wheel helps prevent materials from deviating or falling off the track, ensuring the stable operation of the production line. The construction of the paper guide wheel may include one or more wheels, which are usually mounted on an axle and arranged on both sides of the conveyor belt or work table as needed. This device helps to adjust and maintain the accurate position of materials in industrial production for subsequent processing or transmission. Paper guide wheels are widely used. For example, they can be seen in the printing industry, paper processing, food production lines and other automated systems. By using paper guide wheels, production efficiency can be improved and product quality can be ensured.

[0003] When the paper guide wheel is produced, an injection mold is used for shaping. However, when the existing injection molding device performs injection molding on the injection molds of paper guide wheels of different sizes, the positions of the injection ports of the injection molds are also different due to the different sizes of the paper guide wheels. This requires the staff to spend a lot of time to adjust the position of the injection mold, delaying the production progress. Therefore, a paper guide wheel injection mold structure is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] Depend on Figure 1-4 Provided is a paper guide wheel injection mold structure, comprising an injection molding machine body 1;

[0023] A mold transfer assembly 2 is mounted on the upper end of the work surface of the injection molding machine body 1;

[0024] The mold shifting assembly 2 includes a reciprocating motor 20, the output end of which is connected to a threaded screw 21 and the threaded screw 21 is arranged horizontally. A nut sleeve 22 is meshed and slidably provided on the threaded screw 21, and a sliding block 23 is assembled outside the nut sleeve 22, and a mounting plate 24 is assembled on the upper end of the sliding block 23.

[0025] In this embodiment, by cooperating with each other among the components within the mold shifting assembly 2 and controlling the reciprocating rotation of the reciprocating motor 20, the moving distance of the injection mold 3 assembled on the mounting plate 24 is precisely controlled to ensure that the injection mold 3 can accurately reach the injection position, thereby reducing the adjustment and waiting time, thereby improving production efficiency, allowing staff to complete mold replacement and production preparation work more quickly, reducing production costs, and making the device suitable for various processing needs.

[0026] Specifically, refer to Figure 1-2 Two pads 25 are mounted on the working table of the injection molding machine body 1 and the two pads 25 are arranged in parallel. A slide rail 26 is mounted on each of the two pads 25 .

[0027] In this embodiment, the slide rails 26 are fixedly mounted on the backing plate 25 by bolts, and the two slide rails 26 are arranged in parallel and on both sides of the threaded screw 21 .

[0028] Specifically, refer to Figure 1 Two engaging blocks 27 are slidably engaged on the two slide rails 26 , and the upper ends of the four engaging blocks 27 are connected to the mounting plate 24 .

[0029] In this embodiment, four engaging blocks 27 are respectively engaged and slid on the two slide rails 26, and two engaging blocks 27 on the same side form a group. The upper ends of the four engaging blocks 27 are commonly installed with a mounting plate 24, and the connection between the two is a detachable design.

[0030] Specifically, refer to Figure 2 A limit block 28 is also mounted on the working table of the injection molding machine body 1 , one end of the threaded screw 21 passes through the limit block 28 and a deep groove ball bearing 281 is provided at the connection with the limit block 28 .

[0031] In this embodiment, a limit block 28 is installed on the work table of the injection molding machine body 1. The limit block 28 is used to limit the sliding block 23. When the sliding block 23 slides within the stroke range of the threaded screw 21, the limit block 28 can limit the sliding block 23 to prevent the sliding block 23 from exceeding the stroke range of the threaded screw 21. A deep groove ball bearing 281 is provided at the connection between the threaded screw 21 and the limit block 28 to provide good guidance for the threaded screw 21, reduce the friction between the threaded screw 21 and the limit block 28, and increase the service life of the threaded screw 21 and the limit block 28. At the same time, the deep groove ball bearing 281 can withstand radial and axial loads, ensure that the threaded screw 21 remains stable during movement, and reduce vibration and swing.

[0032] Specifically, refer to Figure 1 A plurality of mounting holes are provided on the upper end surface of the mounting plate 24 and a bearing plate 29 is also mounted on the upper end of the mounting plate 24 , and an injection mold 3 is mounted on the upper end surface of the bearing plate 29 .

[0033] In this embodiment, the several mounting holes provided on the mounting plate 24 can be used for installing bolts. The mounting plate 24 and the supporting plate 29 are installed by bolts. When the supporting plate 29 is worn out too much, the bolts between the two can be removed and the supporting plate 29 can be removed and replaced. At the same time, materials of different sizes and diameters can be installed through the mounting holes provided on the mounting plate 24.

[0034] Specifically, refer to Figure 2 A motor mounting plate 201 is mounted on one side of the reciprocating motor 20 , one end of the threaded screw 21 passes through the center point of the motor mounting plate 201 , and the lower end of the motor mounting plate 201 is connected to the working table of the injection molding machine body 1 .

[0035] In this embodiment, the motor mounting plate 201 is used to mount and fix the reciprocating motor 20 so that the reciprocating motor 20 will not shake or swing when in use.

[0036] The structure of the injection mold for the paper guide wheel of the utility model:

[0037] Before using the device, the user first connects the reciprocating motor 20 to an external power source, then installs the injection mold 3 to be injected on the supporting plate 29, turns on the reciprocating motor 20 and controls the reciprocating rotation of the reciprocating motor 20, so that the reciprocating motor 20 drives the threaded screw 21 connected to the output end to rotate. When the threaded screw 21 rotates, the nut sleeve 22 is engaged with the threaded screw 21, so that the nut sleeve 22 drives the externally installed sliding block 23 to slide within the stroke range of the threaded screw 21. When the sliding block 23 slides, it drives the mounting plate 24 installed at the upper end. Four engaging blocks 27 are installed at the lower end of the mounting plate 24. When the mounting plate 24 slides, the four engaging blocks 27 slide on the two slide rails 26 respectively, so that the mounting plate 24 slides more smoothly. At the same time, when the mounting plate 24 slides, it finally drives the supporting plate 29 installed at the upper end, so that the injection mold 3 installed at the upper end of the supporting plate 29 can accurately reach the injection position for injection.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
