Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a guiding mechanism for molds. Background Technology

[0002] A mold is a tool used for shaping and processing, widely applied in industrial production to manufacture products of various shapes and sizes. Molds play a crucial role in modern industrial production, not only improving production efficiency and ensuring product quality but also reducing production costs. During mold use, the guiding mechanism plays a vital role. Through a precise guiding mechanism, it ensures that the mold moves smoothly and accurately along a predetermined trajectory during its movement, thereby avoiding product molding quality problems caused by deviation.

[0003] Currently, most mold guiding mechanisms use a combination of guide plates and guide rods to achieve the guiding function. The guide rod is usually installed on the fixed part of the mold, while the guide plate is installed on the moving part of the mold. When the moving part of the mold moves, the guide plate slides along the guide rod, thereby achieving precise guidance.

[0004] To improve mold stability and lifespan, springs are typically attached to the outside of guide rods to cushion the impact forces generated during mold movement. While springs effectively reduce mold vibration and wear, they are prone to fatigue, deformation, and even breakage over long-term use. In existing guide mechanism designs, guide rods are usually fixed to the mold, making disassembly difficult. This means that when springs need replacement, maintenance personnel cannot simply remove the guide rod to replace the spring. Instead, they often need to replace the entire mold, increasing maintenance costs and resulting in significant material waste. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a guiding mechanism for molds to solve the problems mentioned in the background art.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figs. 1-3A guiding mechanism for a mold includes a base 1, a lower mold 3 fixedly mounted on the top of the base 1, a positioning hole 2 on the top of the base 1, a support frame 4 fixedly mounted on the top of the base 1, a lifting assembly on the top of the support frame 4, an upper mold 7 mounted on the bottom of the support frame 4 via the lifting assembly, mounting assemblies on both sides of the upper mold 7, guide plates 10 mounted on both sides of the upper mold 7 via the mounting assemblies, guide holes 11 penetrating the top of the guide plates 10, a through hole 12 penetrating the top of the support frame 4, a moving assembly on the top of the support frame 4, and a moving plate 20 mounted on the top of the support frame 4 via the moving assembly. The moving assembly includes components fixedly mounted on the support frame 4. The top frame 13 of the frame 4 is a rectangular frame structure made of stainless steel, which provides higher structural strength and durability. A mounting bracket 14 is fixedly mounted on the surface of the frame 13. A drive motor 15 is fixedly mounted on the right side of the mounting bracket 14. A rotating shaft 16 is fixedly mounted on the output end of the drive motor 15. A first bevel gear 17 is fixedly mounted on the surface of the rotating shaft 16. A second bevel gear 18 is meshed on the surface of the first bevel gear 17. A screw 19 is fixedly mounted inside the second bevel gear 18. The screw 19 is rotatably connected to the frame 13 and threadedly connected to the movable plate 20. The movable plate 20 is connected to the frame 13. The sliding connection, through the setting of the moving component, facilitates the up-and-down movement of the moving plate 20, thereby enabling the moving plate 20 to move automatically up and down. A threaded hole 21 is provided at the bottom of the moving plate 20, and a guide rod 22 is threadedly connected inside the threaded hole 21. Multiple springs 23 are attached to the surface of the guide rod 22, and the springs 23 overlap with the base 1. The positioning hole 2, guide hole 11, and through hole 12 are all adapted to the guide rod 22. This guiding mechanism for the mold, through the cooperation of the guide plate 10 and the guide rod 22, can guide the movement of the upper mold 7. When it is necessary to adjust the spring 23... When replacing the spring 23, the moving plate 20 is moved upward by the moving component, so that the guide rod 22 is in the appropriate position. Then, the spring 23 is pulled out from the bottom of the guide rod 22 and disassembled. Then, the new spring 23 is put on the guide rod 22 from the bottom. Then, the moving plate 20 is moved downward by the moving component, so that the guide rod 22 is moved downward and inserted into the positioning hole 2. The spring 23 can be disassembled and replaced separately, avoiding the need to replace the entire mold. This reduces material waste, and the operation process is relatively simple, which can complete the replacement of the spring 23 more quickly and reduce the downtime of the mold.

[0021] Specifically, the lifting assembly includes a hydraulic push rod 5 fixedly installed on the top of the support frame 4. An installation block 6 is fixedly installed at the output end of the hydraulic push rod 5. The installation block 6 is fixedly connected to the upper mold 7. The lifting assembly facilitates the provision of driving force for the upper mold 7 to move up and down, thereby facilitating the use of the upper mold 7 in conjunction with the lower mold 3 to process products.

[0022] Specifically, the installation components include mounting plates 8 that overlap the left and right sides of the upper mold 7. The mounting plates 8 are fixedly connected to the guide plate 10. Bolts 9 are threaded inside the mounting plates 8 and are fixedly connected to the upper mold 7. By removing the bolts 9 from the upper mold 7 and the mounting plates 8, the fixing of the mounting plates 8 can be removed, and the mounting plates 8 and the guide plate 10 can be disassembled, making the guide plate 10 detachable and easy to replace.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0024] In use: During the up-and-down movement of the mounting block 6 by the hydraulic push rod 5, the upper mold 7 moves up and down. The guide plate 10 and guide rod 22 work together to guide the movement of the upper mold 7. The spring 23, in conjunction with the guide plate 10, provides a buffer for the upper mold 7. When the spring 23 needs to be replaced, the drive motor 15 rotates the shaft 16, causing the first bevel gear 17 to rotate, the second bevel gear 18 to rotate, and the screw 19 to rotate. This causes the moving plate 20 to move upward, and the guide rod 22 to move upward to the appropriate position. Then, the spring 23 is pulled out from the bottom of the guide rod 22 and disassembled. A new spring 23 is then fitted onto the bottom of the guide rod 22. At the same time, the drive motor 15 rotates the shaft 16, causing the first bevel gear 17 to rotate, the second bevel gear 18 to rotate, and the screw 19 to rotate. This causes the moving plate 20 to move downward, and the guide rod 22 to move downward, allowing the guide rod 22 to be inserted into the positioning hole 2.

[0025] Furthermore, when it is necessary to replace the guide rod 22 and the guide plate 10, the drive motor 15 rotates the rotating shaft 16, causing the first bevel gear 17 to rotate, the second bevel gear 18 to rotate, and the screw 19 to rotate, causing the moving plate 20 to move upward. This moves the guide rod 22 upward to a suitable position above the through hole 12, the bolt 9 is removed, and then the guide plate 10 is disassembled. The new guide plate 10 is then placed on the upper mold 7, and the bolt 9 is then installed into the mounting plate 8 and the upper mold 7, completing the guide replacement. After fixing plate 10, guide rod 22 is removed from threaded hole 21, and then a new guide rod 22 is installed into threaded hole 21. Then, drive motor 15 to rotate shaft 16, causing first bevel gear 17 to rotate, second bevel gear 18 to rotate, screw 19 to rotate, moving plate 20 downward, causing guide rod 22 to move downward, so that guide rod 22 passes through through hole 12 and guide hole 11 in succession, while spring 23 is sleeved on guide rod 22 until guide rod 22 is inserted into positioning hole 2.
