Technical Field

[0001] The utility model relates to the technical field of mold locking oil cylinders, in particular to a mold locking oil cylinder which is easy to disassemble and assemble. Background Art

[0002] The clamping cylinder is one of the key driving components in the injection molding machine mold. It is mainly used to provide sufficient clamping force to ensure the stability and accuracy of the mold. Its main functions include clamping, opening, and ejecting molded products. The performance of the clamping cylinder directly affects the production efficiency and product quality of the injection molding machine, so its design and manufacturing are crucial. In modern manufacturing, especially in high-precision, high-efficiency and high-flexibility production lines, the clamping cylinder is particularly widely used.

[0003] However, in the prior art, most of the existing clamping cylinders on the market are fixed designs, that is, once the clamping cylinder is installed on the injection molding machine, the disassembly process is relatively complicated and requires a lot of effort and time. This design limits the efficiency of equipment maintenance and replacement, especially when frequently changing molds or performing equipment maintenance, which increases the workload of operators. In addition, during the installation and removal of the ejector pin of the traditional clamping cylinder, special tools are usually required, and the steps are cumbersome, which poses great operational difficulties and safety hazards. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provide a clamping cylinder which is easy to disassemble and assemble.

[0015] Through the installed auxiliary mechanism, the arc block installed on the outer ring can effectively transmit the shape of the force during the process of pressing the outer ring. When pressing the outer ring, the arc block can effectively transfer the applied force to the part that needs to be operated, ensuring the effective execution of the operation.

[0028] Example 1

[0029] like Figure 1-4 As shown, the utility model provides a technical solution: a clamping cylinder that is easy to disassemble and assemble, comprising: a disassembly mechanism 1, an auxiliary mechanism 2 is arranged on the outside of the disassembly mechanism 1, the disassembly mechanism 1 comprises a cylinder body 11, a sleeve 12 is arranged inside the cylinder body 11, an ejector 13 inside the sleeve 12, a limit block 15 is arranged inside the ejector 13, a spring 14 is arranged inside the limit block 15, a side plate 113 is arranged at one end of the spring 14, the sleeve 12 is arranged at one end of the side plate 113, the limit block A squeeze block 16 is provided on one side of 15, an outer ring 17 is provided at one end of the squeeze block 16, a spring 111 is provided at the bottom of the outer ring 17, a bottom ring 112 is provided at the bottom end of the spring 111, a sleeve 12 is provided on the inner side of the bottom ring 112, a positioning column 18 is provided inside the sleeve 12, a ejector pin 13 is provided on the outer side of one end of the positioning column 18, a vertical rod 19 is provided inside the outer side of the sleeve 12, a fixing block 110 is provided at one end of the vertical rod 19, and the outer side of the fixing block 110 is provided with the outer ring 17.

[0030] In this embodiment, when the device is in use, in order to more quickly disassemble the ejector pin 13 on the mold-locking oil cylinder, the vertical rod 19 is rotated in the outer ring 17 so that the fixed block 110 and the concave groove on the outer ring 17 form a vertical shape, and then the fixed block 110 will no longer restrict the outer ring 17. At this time, the outer ring 17 is pressed down to separate the extrusion block 16 from the limit block 15. After separation, the spring 14 will bring the limit block 15 out of the ejector pin 13 with the side plate 113 as a support point, thereby completing the release of the ejector pin 13. Through this design, the ejector pin 13 on the mold-locking oil cylinder can be disassembled more quickly and conveniently, thereby improving work efficiency and reducing operation time.

[0031] Secondly, when installing the ejector pin 13, the ejector pin 13 is vertically matched with the sleeve 12, and a positioning column 18 is installed in the sleeve 12, so that the structural strength between the two can be increased. At the same time, the pressure of the outer ring 17 is released, and the spring 2 111 will release to reset the outer ring 17, and exert external force on the extrusion block 16 and the limit block 15 again, so that it enters the ejector pin 13, thereby completing its installation, improving the convenience and safety of operation.

[0032] Example 2

[0033] like Figure 1-4 As shown, the auxiliary mechanism 2 includes an arc block 21 , one side of the arc block 21 is fixedly connected to one side of the anti-slip pad 22 , and one end of the arc block 21 is fixedly connected to one side of the outer ring 17 .

[0034] In this embodiment, the arc block 21 installed on the outer ring 17 can effectively transmit the shape of the force during the process of pressing the outer ring 17. When pressing the outer ring 17, the arc block 21 can effectively transfer the applied force to the component that needs to be operated, ensuring the effective execution of the operation, and the arc block 21 is installed with an anti-slip pad 22. The anti-slip pad 22 can increase the friction with the outer ring 17 to prevent the hand from slipping or losing control when pressing the outer ring 17. This can ensure that the operator can press the outer ring 17 more firmly and improve the accuracy and safety of the operation.

[0035] Working principle:

[0036] like Figure 1-4As shown, the vertical rod 19 is rotated in the outer ring 17 so that the fixing block 110 and the recessed groove on the outer ring 17 form a vertical shape, and then the fixing block 110 will no longer restrict the outer ring 17. At this time, by pressing the outer ring 17 downward, the extrusion block 16 and the limit block 15 are separated. After separation, the spring 14 will bring the limit block 15 out of the ejector pin 13 with the side plate 113 as a support point, thereby completing the release of the fixation of the ejector pin 13. Secondly, the ejector pin 13 and the sleeve 12 are vertically matched, and a positioning column 18 is installed in the sleeve 12, which can increase the structural strength between the two. At the same time, the pressure of the outer ring 17 is released, and the spring 2 111 will release to reset the outer ring 17, and exert external force on the extrusion block 16 and the limit block 15 again, so that it enters the ejector pin 13, thereby completing its installation.
