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.

[0019] Example

[0020] See also Figure 1-Figure 3 The plastic mold shown in the figure is easy to disassemble and assemble, including a base 1, a plurality of connecting ears 2 are arranged on both sides of the base 1, the plurality of connecting ears 2 are fixedly connected to a sliding column 3, the sliding column 3 is slidably connected to a sliding sleeve 4, the sliding sleeve 4 is fixedly connected to a pressing plate 5, a tensioning assembly 6 is arranged on the bottom surface of the pressing plate 5, the tensioning assembly 6 is snap-fitted with an upper mold 7, a lower mold 8 is arranged below the upper mold 7, the lower mold 8 is snap-fitted with the tensioning assembly 6, the tensioning assembly 6 includes a limit block 601, the limit block 601 is fixedly connected to a limit rod 602, and the limit rod 602 is slidably connected to a group of horizontally symmetrical clamping blocks 603, the clamp block 603 is slidably connected to the connecting rod 604, and a spring 605 is provided on one side of the clamp block 603. The utility model fixes the tensioning assembly through the base and the pressing plate, and the tensioning assembly is snap-fitted with the upper mold and the lower mold. The tensioning assembly includes a limit block, the limit block is fixedly connected to the limit rod, the limit rod is slidably connected to the clamp block, and the clamp block is slidably connected to the connecting rod. A spring is provided on one side of the clamp block, so that the clamp block can clamp the mold tightly to ensure its stability during the injection molding process, while realizing rapid installation and disassembly of the mold and reducing the difficulty of operation.

[0021] Furthermore, one end of the sliding column 3 is fixedly connected to the top plate 9, and a telescopic cylinder 10 is provided on the top of the top plate 9. The sliding column is used as a key supporting component of the device, which not only ensures the stability of the overall structure, but also fixes one end of the sliding column to the top plate, ensuring that the top plate provides a solid foundation for the telescopic cylinder and subsequent mold fixing operations.

[0022] Furthermore, one end of the telescopic cylinder 10 passes through the top plate 9 and is fixedly connected to the top of the pressing plate 5, and the bottom of the pressing plate 5 is fixedly connected to the limit block 601. By passing one end of the telescopic cylinder through the top plate and being fixedly connected to the top of the pressing plate, the telescopic cylinder can directly control the lifting and lowering of the pressing plate. When the mold needs to be fixed or disassembled, the pressing plate can be easily lifted and lowered by adjusting the length of the telescopic cylinder, thereby achieving rapid tightening or release of the mold.

[0023] Furthermore, the inner side of the limit block 601 is tightly pressed against one end of the spring 605, and the other end of the spring 605 is tightly pressed against the clamping block 603. By tightly pressing one end of the spring against the inner side of the limit block, it is ensured that the spring can work stably under the control of the limit block. The limit block serves as a fixed point, providing a solid support for the spring, and also ensuring that the spring can maintain a stable shape when compressed or stretched, thereby effectively transmitting force. When the mold needs to be fixed, the elastic force of the spring will push the clamping block to clamp the mold tightly, ensuring its stability and accuracy. The elasticity of the spring also enables the clamping block to adapt to molds of different sizes, thereby improving the versatility of the device.

[0024] Furthermore, a steel ball 606 is provided inside the clamp block 603, and the steel ball 606 is tightly pressed against the self-connecting rod 604 through a spring 2 607. Through the combination of the steel ball, spring 2 and the self-connecting rod provided inside the clamp block, the elastic force of spring 2 can ensure that the steel ball and the self-connecting rod maintain close contact, thereby ensuring that the self-connecting rod is restricted and that the self-connecting rod can be stabilized in one position when the mold is replaced.

[0025] Furthermore, the self-restraining connecting rod 604 includes a connecting rod 608, one end of which is fixedly connected to a steel ball base 609, and the steel ball base 609 is internally rotatably connected to a steel ball 2 610. A limit plate 611 is provided in the middle of the connecting rod 608, and a spring 3 612 is provided on one side of the limit plate 611. The other end of the connecting rod 608 is slidably connected to an adjustment plate 613. The self-restraining connecting rod includes one end of the connecting rod fixedly connected to the steel ball base, and the steel ball 2 rotatably connected inside the steel ball base enhances the flexibility and smoothness of the self-restraining connecting rod, reduces friction resistance, and enables the self-restraining connecting rod to move and rotate more smoothly when subjected to force. When the connecting rod is subjected to external force, the spring 3 can absorb part of the impact force to protect the device from damage; and when the external force disappears, the spring 3 can quickly reset the connecting rod to ensure the fixing effect of the mold.

[0026] Furthermore, the lower part of the upper mold 7 and the lower mold 8 are provided with limiting grooves, and the limiting grooves tightly press the steel ball 2 610. The steel ball 2 610 is rotatably connected to the lower part of the upper mold 7 and the lower mold 8. The limiting grooves provided at the lower part of the upper mold and the lower mold provide a precise embedding position for the steel ball 2, ensuring that the steel ball 2 can function stably at a specific position and will not shift due to the movement or vibration of the mold. During the mold fixing process, the steel ball 2 can rotate freely in the limiting groove to adapt to the slight deviation of the mold, ensuring that the mold can be quickly and accurately aligned, simplifying the mold alignment process and improving the replacement efficiency.

[0027] In this solution, the workflow is: when the upper mold and the lower mold need to be fixed, the pressing plate is first controlled by the telescopic cylinder to move downward along the sliding column. As the pressing plate descends, the tensioning assembly at its bottom begins to contact the upper mold and the lower mold.

[0028] In the tensioning assembly, the limit block pushes the spring and the clamping block inward to clamp, and at the same time the self-adapting connecting rod is adaptively adjusted through its internal spring and steel ball structure to ensure tight clamping.

[0029] When the second steel ball is embedded in the limiting grooves provided in the upper mold and the lower mold, the mold is accurately positioned and fixed.

[0030] After the mold is fixed, the injection molding of the plastic product can be carried out. After the injection molding is completed, the pressing plate is controlled to rise by the telescopic cylinder. Then, the molded product can be easily taken out and the next round of injection molding or mold replacement can be carried out.

[0032] Although the 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.
