Description

Technical Field

[0001] The utility model relates to the technical field of hardware moulds, in particular to a small-sized hardware mould quick-installation and resetting tool. Background Art

[0002] Hardware molds are made in industrial production by using various presses and special tools installed on the presses to press metal materials into parts or products of the desired shape through pressure. These special tools are collectively called hardware molds. When the mold is in use, the mold is generally reset through a reset tool to facilitate disassembly and quickly remove the hardware in the mold, thereby improving the efficiency of mold processing.

[0003] In the Chinese patent with publication number CN214078892U, a small hardware mold quick-install reset tooling is disclosed. By moving the limit plate to change its own height position, the extension plate is pressed by the limit plate to drive the lower template to change its own height. At this time, the reset spring undergoes elastic deformation, and the limit plate can adjust the maximum pop-up height of the lower template pushed by the reset spring. After the die pressing is completed, the lower template is quickly reset by the release of the elastic potential energy of the reset spring to pop out the hardware mold, which is convenient for personnel to carry out unloading work; however, when the above-mentioned small hardware mold quick-install reset tooling is actually used, the template is generally pushed out and reset by spring compression. The spring is prone to elastic fatigue after long-term use, and the user needs to replace it to ensure the normal reset of the template. However, when the existing spring is replaced, most of the extension plates are blocked by the limit plate, so that the template is hindered during disassembly, which makes it difficult to quickly disassemble the spring, which may increase the time required for the spring in the disassembly process, and is time-consuming and labor-intensive, reducing the practicality of the reset tooling. Utility Model Content

[0004] The purpose of the utility model is to provide a small hardware mold quick-assembly and resetting tool. Through the setting of the disassembly and assembly components, the extension plate and the limit plate can be disconnected, so that the template can be ejected in the square frame plate, thereby realizing the rapid replacement of the first spring. The problem that the existing limit plate blocks the extension plate, so that the square frame plate is hindered during disassembly, resulting in difficulty in rapid disassembly of the spring, which may increase the time required for the disassembly process of the spring, is solved. The utility model saves time and effort, greatly improves the practicability of the use of the resetting tool, and solves the above-mentioned deficiencies in the technology.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-Figure 3 A small hardware mold quick-install reset tool shown, comprising:

[0027] Two symmetrically distributed square frame plates 11 are installed on the mounting frame 1, and templates 12 are installed in both square frame plates 11, a first spring 13 is installed in the square frame plate 11, and the first spring 13 is used to push the template 12 to reset in the square frame plate 11, a limiting plate 14 is installed in the square frame plate 11, and an extension plate 15 matching the limiting plate 14 is installed on one side of the template 12; and a threaded seat is installed at the bottom end of the first spring 13, so that the threaded seat and the square frame plate 11 are screwed together to maintain a firm state between the first spring 13 and the square frame plate 11; wherein, the structures and principles of the mounting frame 1 and the limiting plate 14 are prior arts, and specific reference may be made to the comparative document (publication number CN214078892U, and the patent name is a small hardware mold quick-install reset tooling), which will not be repeated here.

[0028] As can be seen from the above, when in use, the hardware mold is placed on the upper surface of the template 12 according to the processing requirements, and then the two square frame plates 11 are closed to complete the die pressing work on the hardware. At this time, the other square frame plate 11 moves upward, and the first spring 13 is compressed and reset, thereby giving an upward thrust to one side of the template 12, and then the template 12 is pushed to move upward along the square frame plate 11, and the movement of the template 12 drives the extension plate 15 to approach the bottom end of the limit plate 14 in the square frame plate 11, and then the limit plate 14 and the extension plate 15 are in conflict with each other, which is used to limit the upward moving position of the template 12 in the square frame plate 11, and then the template 12 is quickly reset by the release of the elastic potential energy of the first spring 13 to pop out the hardware mold, which is convenient for personnel to unload.

[0029] refer to Figure 2-Figure 5As shown, the disassembly assembly 2 includes a slide groove 21 provided at the bottom of the template 12 for the extension plate 15 to slide, and a second spring 22 installed in the slide groove 21, and one end of the second spring 22 conflicts with the extension plate 15, and a control assembly is provided on the limit plate 14 to push the extension plate 15 to move; the control assembly includes a conflicting block 26 fixed to one side of the extension plate 15 and a threaded rod 24 screwed through the top of the limit plate 14, an eccentric wheel 25 is fixed to the bottom end of the threaded rod 24, and the outer portion of the eccentric wheel 25 conflicts with the conflicting block 26;

[0030] A slider 23 is fixed to one side of the extension plate 15 , and a limit groove corresponding to the slider 23 is provided in the slide groove 21 ; a rotating disk 27 is fixed to one end of the threaded rod 24 relative to the eccentric wheel 25 , and an arc pad is fixed to the outside of the rotating disk 27 .

[0031] Through the above technical solution:

[0032] When the first spring 13 needs to be replaced, the rotating disk 27 is gripped and rotated, so that the rotating disk 27 rotates and drives the threaded rod 24 to screw with the limit plate 14. At this time, the threaded rod 24 moves upward along the limit plate 14, and the rotation of the threaded rod 24 drives the eccentric wheel 25 to rotate synchronously at the bottom end of the limit plate 14 and pulls the eccentric wheel 25 upward. Moreover, when the eccentric wheel 25 rotates, it slides along the outside of the resistance block 26 and pushes the resistance block 26 to move into the inside of the slide groove 21. However, the movement of the resistance block 26 pushes the extension plate 15 to move along the slide groove 21. As the extension plate 15 moves, the slider 23 is driven to move synchronously along the limit groove, so that the second spring 22 is compressed. Subsequently, after the top end of the eccentric wheel 25 contacts the bottom end of the limit plate 14, the outer protruding part of the eccentric wheel 25 is located at the resistance block 26. The top of the block 26 makes the outside of the resistance block 26 remain level with one side of the limit plate 14, and then the elastic potential energy of the first spring 13 is released to push the template 12 to move, so that one side of the resistance block 26 slides upward along the eccentric wheel 25 and the side of the limit plate 14, exposing the template 12 and the first spring 13 to the outside of the square frame plate 11, and then the extension plate 15 and the limit plate 14 can be disconnected, so that the template 12 can be ejected in the square frame plate 11 to achieve rapid replacement of the first spring 13, which solves the problem that the existing limit plate 14 blocks the extension plate 15, which hinders the square frame plate 11 during disassembly, making it difficult to quickly disassemble the first spring 13, and may increase the time required for the disassembly process of the first spring 13, saving time and effort, and improving the practicality of the reset tooling.

[0033] In addition, refer to Figure 3-Figure 5As shown, a protection component 3 is installed on the limiting plate 14, and the protection component 3 is used to protect the rotating disk 27. The protection component 3 includes a positioning cavity 35 opened at the top of the limiting plate 14 and a sleeve 31 slidably sleeved on the outside of the rotating disk 27, and the sleeve 31 is slidably connected to the positioning cavity 35. A guide component is provided in the sleeve 31 to position it with the rotating disk 27;

[0034] The guide assembly includes a moving block 33 fixed in the sleeve 31 and a guide groove 32 opened at the top of the rotating disk 27, and the moving block 33 is slidably connected to the guide groove 32; a guide groove 34 communicating with the inside of the guide groove 32 is also opened at the bottom end of the rotating disk 27, and the moving block 33 is slidably connected to the guide groove 34.

[0035] Through the above technical solution:

[0036] When the adjustment of the rotating disk 27 is completed, the sleeve 31 is sleeved on the outside of the rotating disk 27 and the sleeve 31 is pressed downward, and then the sleeve 31 moves downward along the outside of the rotating disk 27, so that the sleeve 31 moves and pushes the moving block 33 to move downward along the guide groove 32. At this time, the moving block 33 conflicts with the bottom wall inside the guide groove 32, and the sleeve 31 partially slides into the positioning cavity 35. The rotating sleeve 31 drives the moving block 33 to slide into the guide groove 34 in the guide groove 32, and after the moving block 33 conflicts with the guide groove 34, the sleeve 31 is continued to be pressed so that the moving block 33 moves in the guide groove The sleeve 31 moves into the positioning cavity 35, and the top of the sleeve 31 contacts the top of the rotating disk 27, and the sleeve 31 slides into the positioning cavity 35, and then the sleeve 31 is rotated to move the moving block 33 in the positioning cavity 35. At the same time, the sleeve 31 rotates along the outside of the rotating disk 27 and cannot rotate the rotating disk 27, thereby protecting the rotating disk 27 and ensuring that the rotating disk 27 is fixed at the desired position to prevent the rotating disk 27 from sliding due to accidental contact, thereby effectively improving the stability of the rotating disk 27 and enhancing the stability between the template 12 and the square frame plate 11.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
