Description
Technical Field
[0001] This utility model relates to the field of mold guide post technology, specifically a replaceable mold guide post. Background Technology
[0002] Mold guide pillars are one of the commonly used accessories for molds. They are guide elements used in combination with components in molds to ensure that the mold moves in a precise position and guide the mold stroke. The guide pillars can control the up and down movement of the mold. Since the guide pillars need to be used for a long time, their lifespan is often related to the lifespan of the entire mold. Once damaged, they need to be disassembled and replaced.
[0003] Current disassembly methods typically involve directly disassembling the mold guide pillar into numerous sub-sections, which is cumbersome and can easily damage the parts, affecting the performance of the mold guide pillar. To address these issues, we propose a replaceable mold guide pillar. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A replaceable mold guide pillar includes a guide pillar body, a base at one end of the guide pillar body, a connecting assembly at the end of the guide pillar body near the base, the guide pillar body being fixed to the base via the connecting assembly, a threaded hole on the side of the base near the guide pillar body, limit grooves on both sides of the inner wall of the threaded hole, a guide pillar fixedly connected to the bottom of the inner cavity of the threaded hole, a telescopic spring sleeved on the surface of the guide pillar, one end of the telescopic spring being fixedly connected to the bottom of the inner cavity of the threaded hole, and a cone seat fixedly connected to the other end of the telescopic spring, the connecting assembly including an assembly cylinder, the end of the assembly cylinder away from the base being fixedly connected to the guide pillar body, assembly windows on both sides of the assembly cylinder, buttons built into the assembly windows, a connecting plate fixedly connected to one end of the button inside the assembly cylinder, and a limit seat fixedly connected to the end of the connecting plate near the base.
[0007] Preferably, the limiting grooves on both sides are symmetrically distributed along the base axis, and the conical surface of the conical seat faces the guide post body.
[0008] Preferably, the axes of the assembly cylinder, base, and guide post body coincide.
[0009] Preferably, a connecting ring is fixedly connected to the side of the assembly cylinder near the base, and the outer surface of the connecting ring is provided with an external thread that matches the threaded hole, and the connecting ring is threadedly connected to the base.
[0010] Preferably, the assembly windows on both sides are symmetrically distributed along the axis of the assembly cylinder, and the button is slidably connected to the inner wall of the assembly window.
[0011] Preferably, the two connecting plates have mounting grooves on their close-to-each end faces, and each mounting groove contains a reset spring, with both ends of the reset spring being fixedly connected to the bottom of the inner cavity of the two mounting grooves.
[0012] Preferably, the limiting seat has a triggering inclined surface that matches the cone surface on the side near the cone seat, and the limiting seat and the cone seat are slidably connected through the triggering inclined surface.
[0013] Preferably, the assembly cylinder has limiting windows on both sides to facilitate the passage of the limiting seat, and the end of the limiting seat away from the center of the assembly cylinder passes through the limiting window and is slidably connected to the wall of the limiting groove.
[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0015] The guide post fixing effect of this utility model is extremely good. It adopts a dual fixing method of threaded connection and limit seat. The threaded connection between the connecting ring and the threaded hole provides initial fixing. After the limit seat enters the limit groove, the fixing effect is further enhanced.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0024] Example: Figures 1-5 As shown, this utility model provides a replaceable mold guide post, including a guide post body 1, a base 2 at one end of the guide post body 1, a connecting component 3 installed at the end of the guide post body 1 near the base 2, the guide post body 1 being fixed to the base 2 via the connecting component 3, a threaded hole 201 being provided on the side of the base 2 near the guide post body 1, limit grooves 202 being provided on both sides of the inner wall of the threaded hole 201, the limit grooves 202 being symmetrically distributed along the axis of the base 2, a guide post 203 being fixedly connected to the bottom of the inner cavity of the threaded hole 201, a telescopic spring 204 being sleeved on the surface of the guide post 203, one end of the telescopic spring 204 being fixedly connected to the bottom of the inner cavity of the threaded hole 201, and a cone seat 205 being fixedly connected to the other end of the telescopic spring 204, the cone surface of the cone seat 205 facing the guide post body 1, during installation, the guide post body 1 is brought close to the base 2, and the connecting ring 302 on the assembly cylinder 301 is threadedly connected to the threaded hole 201 of the base 2. As the assembly cylinder 301 is gradually screwed into the threaded hole 201, the cone seat 205 approaches the limiting seat 309. The cone surface of the cone seat 205 contacts and presses against the triggering inclined surface 310 of the limiting seat 309, causing the limiting seat 309 to pass through the limiting windows 311 on both sides of the assembly cylinder 301 under the action of the pressing force and enter the limiting grooves 202 on both sides of the inner wall of the threaded hole 201 of the base 2, thereby achieving fixation. The dual fixing method of threaded connection and limiting seat 309 is more secure than the original simple threaded fixation, which can effectively prevent the mold guide pillar from loosening during operation, improve the accuracy and stability of the mold, avoid the problem of many parts and easy damage in the traditional direct subdivision disassembly method, reduce the maintenance cost of the mold guide pillar, and extend its service life.
[0025] Furthermore, the connecting assembly 3 includes an assembly cylinder 301. The end of the assembly cylinder 301 furthest from the base 2 is fixedly connected to the guide post body 1. The axes of the assembly cylinder 301, base 2, and guide post body 1 coincide. A connecting ring 302 is fixedly connected to the side of the assembly cylinder 301 closest to the base 2. The outer surface of the connecting ring 302 has an external thread 303 that matches the threaded hole 201. The connecting ring 302 is threadedly connected to the base 2. Assembly windows 304 are provided on both sides of the assembly cylinder 301, symmetrically distributed along the axis of the assembly cylinder 301. A button 305 is built into each assembly window 304, slidingly connected to the inner wall of the assembly window 304. A connecting plate 306 is fixedly connected to one end of the button 305 inside the assembly cylinder 301. The ends of the two connecting plates 306 are close to each other. The mounting plate 306 has a mounting groove 307, and a reset spring 308 is built into the mounting groove 307. The two ends of the reset spring 308 are fixedly connected to the bottom of the inner cavity of the two mounting grooves 307 respectively. The end of the connecting plate 306 near the base 2 is fixedly connected to a limiting seat 309. The side of the limiting seat 309 near the cone seat 205 has a triggering inclined surface 310 that matches the cone surface. The limiting seat 309 and the cone seat 205 are slidably connected through the triggering inclined surface 310. The two sides of the assembly cylinder 301 have limiting windows 311 to facilitate the limiting seat 309 to pass through. The end of the limiting seat 309 away from the center of the assembly cylinder 301 passes through the limiting window 311 and is slidably connected to the wall of the limiting groove 202. By pressing the buttons 305 on both sides of the assembly cylinder 301, the buttons 305 drive the connecting plate 306 to move towards the center of the assembly cylinder 301. The connecting plate 306 moves the limiting seat 309 towards the center of the assembly cylinder 301, causing the limiting seat 309 to disengage from the cone seat 205. Under the action of the telescopic spring 204, the cone seat 205 approaches the bottom of the threaded hole 201. At this time, the limiting seat 309 disengages from the limiting groove 202. Then, by rotating the guide post body 1 in the opposite direction, disassembly can be completed. During disassembly, simply pressing the button 305 will disengage the limiting seat 309 from the limiting groove 202, and then rotating the guide post body 1 in the opposite direction will complete the disassembly. The operation is simple and quick, reducing disassembly time and workload.
[0026] Working Principle: The mold guide pillar mainly consists of a guide pillar body 1, a base 2, and a connecting assembly 3. During installation, the guide pillar body 1 is brought closer to the base 2, at which point the connecting ring 302 on the assembly cylinder 301 is threadedly connected to the threaded hole 201 on the base 2. As the assembly cylinder 301 is continuously screwed into the threaded hole 201, the conical seat 205 inside the assembly cylinder 301 gradually approaches the limiting seat 309. Since the conical surface of the conical seat 205 faces the guide pillar body 1, and the limiting seat 309 has a triggering inclined surface 310 matching the conical surface on the side closest to the conical seat 205, a squeezing effect is generated when the conical seat 205 contacts the limiting seat 309. Under the push of this squeezing force, the limiting seat 309 passes through the limiting windows 311 on both sides of the assembly cylinder 301 and enters the limiting grooves 202 on both sides of the inner wall of the threaded hole 201 of the base 2, thereby realizing the fixed installation of the mold guide pillar.
[0027] During disassembly, the buttons 305 on both sides of the assembly cylinder 301 are pressed. The buttons 305 are slidably connected to the inner wall of the assembly window 304. When the buttons 305 are pressed, they move the connecting plate 306 towards the center of the assembly cylinder 301. A limiting seat 309 is fixedly connected to the connecting plate 306. As the connecting plate 306 moves, the limiting seat 309 also moves towards the center of the assembly cylinder 301, releasing the contact between the limiting seat 309 and the cone seat 205. At this time, the cone seat 205 moves closer to the bottom of the threaded hole 201 under the action of the telescopic spring 204. After the limiting seat 309 disengages from the limiting groove 202, the guide pillar body 1 is rotated in the opposite direction to complete the disassembly of the mold guide pillar.
[0028] The mold guide pillar employs a dual fixing method: threaded connection and limiting seat 309. On one hand, the threaded connection between the connecting ring 302 and the threaded hole 201 provides initial fixing; on the other hand, the limiting seat 309, after entering the limiting groove 202, further enhances the fixing effect. Compared to the original simple threaded fixing, this dual fixing method is more robust, effectively preventing the mold guide pillar from loosening due to various external forces during operation, ensuring the precision and stability of the mold, and providing a strong guarantee for high-quality mold production. Traditional mold guide pillar disassembly methods are usually cumbersome, requiring direct disassembly of the mold guide pillar into numerous sub-parts, which is not only complex to operate but also prone to damage. However, with this replaceable mold guide pillar, disassembly is simple: just press button 305 to disengage the limiting seat 309 from the limiting groove 202, and then rotate the guide pillar body 1 in the opposite direction to complete the disassembly. This operation is simple and quick, greatly reducing disassembly time and workload, and improving production efficiency. The design of this mold guide pillar is highly adaptable and can meet the needs of different types of molds. Whether it's a small or large mold, you can choose the appropriate mold guide pillars according to the actual situation, which improves the flexibility and versatility of mold design.
[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
