Description

Technical Field

[0001] This utility model belongs to the field of mold manufacturing technology, and in particular relates to a positioning and clamping mechanism for processing mold guide pillars. Background Technology

[0002] Mold guide pillars are guiding elements in the mold structure. With the development of mold technology and the improvement of production needs, the requirements for positioning and clamping of mold guide pillars during processing are becoming increasingly higher. Precise positioning and effective clamping can not only improve processing accuracy and efficiency, but also ensure the quality and service life of mold guide pillars, thereby ensuring the performance of the entire mold.

[0003] When existing positioning clamping mechanisms clamp positioning guide posts, if the design or adjustment of the positioning clamping mechanism is not proper, the positioning guide post may shift due to uneven force during clamping. Long-term use will lead to local material fatigue, cracks or breakage of the positioning guide post, thereby reducing the service life of the guide post.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] This utility model addresses the problem in existing technologies where, due to improper design or adjustment of the positioning clamping mechanism, uneven force causes displacement when clamping the positioning guide post. Prolonged use of this mechanism can lead to localized material fatigue, cracking, or breakage of the positioning guide post, thus reducing its service life. The following technical solution is proposed:

[0006] A positioning and clamping mechanism for machining mold guide pillars includes:

[0007] A positioning guide post is provided with an upper mold and a lower mold. The positioning guide post is connected to the lower mold, and the upper mold reciprocates vertically on the positioning guide post.

[0008] The clamping assembly includes a connecting rod, a locking block, a threaded component, and a positioning component. The connecting rod slides within the positioning guide post and the lower mold. The locking block slides along the surface of the connecting rod within the lower mold. The threaded component rotates within the lower mold via the positioning component and is threadedly connected to the inside of the locking block.

[0009] As a preferred embodiment of the above technical solution, a synchronization component is also included. The synchronization component includes a first linkage wheel, a second linkage wheel, and a linkage bar. Two threaded components are provided. The first linkage wheel and the second linkage wheel are respectively connected to two different threaded components. The first linkage wheel and the second linkage wheel are aligned in the horizontal direction. The first linkage wheel and the second linkage wheel are simultaneously connected to the same linkage bar, and the linkage bar moves in the horizontal direction inside the lower mold.

[0010] As a preferred embodiment of the above technical solution, the connecting rod passes through the interior of the locking block and the positioning guide post, and the inner walls of the locking block and the positioning guide post are in contact with the surface of the connecting rod to restrict the connecting rod during movement.

[0011] As a preferred embodiment of the above technical solution, four positioning elements are provided, which are evenly distributed at the two end edges of the two threaded elements to restrict the threaded elements during rotation.

[0012] As a preferred embodiment of the above technical solution, one of the threaded parts is provided with a rotating part, which is located at the end of the surface of one of the threaded parts away from the first linkage wheel.

[0013] As a preferred embodiment of the above technical solution, the connecting rod is provided with a magnetic component, and the magnetic component is provided with a handle, the handle being located at the end of the magnetic component away from the connecting rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) The positioning guide post is clamped by the clamping block, which avoids the problem of the guide post shifting due to uneven force, thereby improving the stability of the positioning guide post when it is installed inside the lower mold, and thus improving the service life of the positioning guide post.

[0016] (2) Through the cooperation between the first linkage wheel, the second linkage wheel and the linkage bar, the two threaded parts rotate synchronously. The synchronous rotation of the two threaded parts makes the movement of the locking block more stable and avoids the deviation caused by the asynchronous movement of the locking block.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a positioning and clamping mechanism for machining mold guide pillars, such as... Figures 1 to 4As shown, it includes: positioning guide pillars 1 and clamping components. The positioning guide pillars 1 are equipped with an upper mold 2 and a lower mold 3. The positioning guide pillars 1 are connected to the lower mold 3. The upper mold 2 reciprocates vertically on the positioning guide pillars 1. There are four positioning guide pillars 1, located at the corners of the lower mold 3. Both the positioning guide pillars 1 and the lower mold 3 have mounting slots. The clamping components include connecting rods 4, locking blocks 5, threaded parts 6, and positioning parts 7. There are two locking blocks 5, with their jaws facing each other, enclosing the positioning guide pillars 1. The threaded parts 6 are bidirectional screws. The connecting rods 4... The positioning guide post 1 and the mounting groove on the lower mold 3 slide inside each other. The locking block 5 slides along the surface of the connecting rod 4 inside the lower mold 3. The threaded part 6 rotates inside the lower mold 3 through the positioning part 7, and the threaded part 6 is threadedly connected to the inside of the locking block 5. The connecting rod 4 passes through the inside of the locking block 5 and the positioning guide post 1, and the inner walls of the locking block 5 and the positioning guide post 1 are in contact with each other with the surface of the connecting rod 4, which is used to restrict the connecting rod 4 during the movement. There are four positioning parts 7, which are evenly distributed at the two ends of the two threaded parts 6, and are used to restrict the threaded parts 6 during the rotation.

[0028] By clamping the positioning guide post 1 with the clamping block 5, the problem of the guide post shifting due to uneven force is avoided, thereby improving the stability of the positioning guide post 1 when it is installed inside the lower mold 3, and thus improving the service life of the positioning guide post 1.

[0029] In use, when the operator needs to install the positioning guide post 1 inside the lower mold 3, the operator pulls the magnetic component 12 through the handle 13 to separate it from the lower mold 3. As the magnetic component 12 moves, it drives the connecting rod 4 to move horizontally within the lower mold 3 and the locking block 5. The operator then installs the positioning guide post 1 inside the lower mold 3, aligning the mounting groove inside the lower mold 3 with the mounting groove on the lower mold 3 horizontally. The operator then inserts the connecting rod 4 inside the lower mold 3 and moves it in the opposite direction. The connecting rod 4 drives the magnetic component 12 and the handle 13 to move synchronously, and the connecting rod 4 passes through the locking block as it moves. Inside the positioning guide post 1 and the locking block 5, the positioning guide post 1 is locked and limited until the magnetic component 12 is magnetically attracted to the lower mold 3. Then the connecting rod 4 stops moving. At this time, the operator rotates the rotating component 11, which drives the threaded component 6 to rotate. When the threaded component 6 rotates, the two locking blocks 5 move closer to each other and clamp the positioning guide post 1, thus completing the clamping step of the positioning guide post 1. By clamping the positioning guide post 1 with the locking block 5, the problem of the guide post shifting due to uneven force is avoided, thereby improving the stability of the positioning guide post 1 when it is installed inside the lower mold 3, and thus improving the service life of the positioning guide post 1.

[0030] Specifically, four positioning guide pillars 1 are snapped into the interior of the lower mold 3. These four positioning guide pillars 1 are evenly distributed at the corners of the lower mold 3. The upper mold 2 is simultaneously fitted onto the outer surface of the four positioning guide pillars 1, and moves vertically on the outer surface of the positioning guide pillars 1. A single positioning guide pillar 1 and the interior of the lower mold 3 are slidably connected by the same connecting rod 4. A magnetic component 12 is fixedly connected to the end of the connecting rod 4 away from the lower mold 3, and a handle 13 is fixedly connected to the end of the magnetic component 12 away from the connecting rod 4. Two locking blocks 5 are slidably connected to the outer surface of the connecting rod 4, and the two locking blocks 5 enclose the positioning guide pillar 1. Threaded components 6 are threadedly connected inside the locking blocks 5, and there are two threaded components 6. The two threaded components 6 are located at the two ends of the locking blocks 5, respectively. Each threaded component 6 has a positioning component 7 at both ends, and the threaded component 6 rotates inside the lower mold 3 through the positioning component 7.

[0031] To address the issue of block 5 shifting during movement, as illustrated in the example above, the following solution is proposed: Figures 1 to 4 As shown, it also includes a synchronization component, which includes a first linkage wheel 8, a second linkage wheel 9, and a linkage bar 10. Both the first linkage wheel 8 and the second linkage wheel 9 are gears, and the linkage bar 10 is a rack. A single linkage bar 10 is simultaneously engaged with both the first linkage wheel 8 and the second linkage wheel 9. There are two threaded parts 6. The first linkage wheel 8 and the second linkage wheel 9 are respectively connected to two different threaded parts 6, and the first linkage wheel 8 and the second linkage wheel 9 are aligned in the horizontal direction. The first linkage wheel 8 and the second linkage wheel 9 are simultaneously connected to the same linkage bar 10, and the linkage bar 10 moves horizontally inside the lower mold 3. One of the threaded parts 6 is provided with a rotating part 11, which is located at the end of the surface of one of the threaded parts 6 away from the first linkage wheel 8. The connecting rod 4 is provided with a magnetic part 12, and the magnetic part 12 is provided with a handle 13, which is located at the end of the surface of the magnetic part 12 away from the connecting rod 4.

[0032] The coordination between the first linkage wheel 8, the second linkage wheel 9, and the linkage bar 10 enables the two threaded parts 6 to rotate synchronously. The synchronous rotation of the two threaded parts 6 makes the movement of the locking block 5 more stable and avoids the deflection caused by the asynchronous movement of the locking block 5.

[0033] In use, when the rotating part 11 rotates, it drives one of the threaded parts 6 to rotate. One of the threaded parts 6 drives the first linkage wheel 8 to rotate. The first linkage wheel 8 drives the linkage bar 10 to move horizontally inside the lower mold 3. During the movement, the linkage bar 10 drives the second linkage wheel 9 to rotate, and through the second linkage wheel 9, it drives the other threaded part 6 to rotate. When the two threaded parts 6 rotate synchronously, the locking block 5 can move stably along the threads on the surfaces of the two threaded parts 6. Through the cooperation between the first linkage wheel 8, the second linkage wheel 9, and the linkage bar 10, the two threaded parts 6 rotate synchronously. The synchronous rotation of the two threaded parts 6 makes the movement of the locking block 5 more stable and avoids the skewing caused by the asynchronous movement of the locking block 5.

[0034] Specifically, one end face of one threaded part 6 is fixedly connected to a rotating part 11, and the end of one threaded part 6 away from the rotating part 11 is fixedly connected to a first linkage wheel 8. The end face of the other threaded part 6 is fixedly connected to a second linkage wheel 9. Both the first linkage wheel 8 and the second linkage wheel 9 penetrate the interior of the positioning part 7. The first linkage wheel 8 and the second linkage wheel 9 are aligned in the horizontal direction, and the surfaces of the first linkage wheel 8 and the second linkage wheel 9 are simultaneously engaged with a linkage bar 10. The linkage bar 10 moves horizontally inside the lower mold 3.

[0035] Working Principle: When using this device, if the operator needs to install the positioning guide post 1 inside the lower mold 3, the operator pulls the magnetic component 12 through the handle 13 to separate it from the lower mold 3. As the magnetic component 12 moves, it drives the connecting rod 4 to move horizontally within the lower mold 3 and the locking block 5. The operator then installs the positioning guide post 1 inside the lower mold 3, aligning the mounting groove inside the lower mold 3 with the mounting groove on the lower mold 3 horizontally. The operator then inserts the connecting rod 4 into the lower mold 3 and moves it in the opposite direction. The connecting rod 4 drives the magnetic component 12 and the handle 13 to move synchronously. As the connecting rod 4 moves, it penetrates the interior of the locking block 5 and the positioning guide post 1, locking and limiting the movement of the locking block 5 and the positioning guide post 1 until the magnetic component 12 magnetically attracts the lower mold 3. At this point, the operator can stop moving. Rotating the rotating component 11 causes one of the threaded components 6 to rotate, which in turn drives the first linkage wheel 8 to rotate. The first linkage wheel 8 drives the linkage bar 10 to move horizontally inside the lower mold 3. During this movement, the linkage bar 10 drives the second linkage wheel 9 to rotate, which in turn drives the other threaded component 6 to rotate. When the two threaded components 6 rotate synchronously, the clamping block 5 can move stably along the threads on the surfaces of the two threaded components 6. During the movement, the two clamping blocks 5 move closer to each other and clamp the positioning guide post 1, thus completing the clamping step of the positioning guide post 1. By clamping the positioning guide post 1 with the clamping block 5, the problem of the guide post shifting due to uneven force is avoided, thereby improving the stability of the positioning guide post 1 when it is installed inside the lower mold 3, and thus increasing the service life of the positioning guide post 1.

[0036] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
