Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of swing mold bottom fixtures, and particularly relates to a swing mold bottom fixture with an integrated anti-displacement structure. Background Technology
[0002] The swaying mold base fixture is a key tooling equipment in industries such as mold manufacturing, injection molding, and stamping. It is mainly used to safely and stably store and maintain molding molds outside the production line. In the traditional sense, the swaying mold base fixture usually consists of a rigid base and several simple positioning blocks or limit pins. Its core function is to provide physical support for the mold and rely on the contact between the mold's own weight and the side limit blocks to maintain its relative position stability.
[0003] To improve mold stability, some fixtures are equipped with pressure plates or clamping plates to further secure the mold. However, these fixtures have the following technical problems during use: existing pressure plates or clamping plates are usually connected and driven by threaded pairs, and the operating parts such as the ends of the threaded rods are usually exposed. These exposed operating parts are easily touched by personnel or tools, causing the threaded pairs to rotate unexpectedly, which in turn loosens the locked mold and causes the mold to shift. Summary of the Invention

[0010] In a preferred embodiment of the present invention, the top of the threaded rod is rotatably connected to the bottom of the rotating rod, and a long spline hole is provided through the interior of the rotating rod, the long spline hole being adapted to a short spline hole.
[0011] As a preferred embodiment of the present invention, a long spline rod is slidably inserted into the long spline hole, and the bottom of the long spline rod can be inserted into the short spline hole.
[0012] As a preferred embodiment of the present invention, the upper outer circumference of the rotating rod is provided with a plurality of anti-slip grooves, the lower outer circumference is provided with a placement groove, the bottom of the placement groove is provided with a groove, and the pressure rod is hinged in the placement groove.
[0013] As a preferred embodiment of the present invention, the threaded rod includes: the threaded rod includes a body and a cover, the cover is fixedly connected to the upper end of the cover, the mounting groove is located at the upper end of the body, and the mounting groove is located in the cover.
[0014] As a preferred embodiment of the present invention, the side of the long spline rod is provided with a vertically arranged slide rail, and two symmetrically arranged limiting strips are fixedly connected to the outer side of the slide rail, and there is a gap channel between the two limiting strips. The upper end of the limiting strip has a locking interface, and the locking interface is part of the slide rail. The bottom of the placement groove has a limiting hole, the bottom of the pressure rod is fixedly connected to a limiting rod, and the end of the limiting rod is fixedly connected to a snap-fit protrusion. The snap-fit protrusion can snap into the snap-fit interface, and the width of the limiting rod is smaller than the width of the gap channel.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a limiting threaded sleeve to initially limit the target mold, and then uses an unfolded pressure bar to fix the target mold a second time, which can effectively prevent the target mold from shifting and improve its stability.
[0016] 2. This invention achieves the switching between rigid transmission during operation and motion decoupling during non-operation by inserting and separating the spline rod. In the non-operation state, the rotating rod and the threaded rod can rotate freely relative to each other.

Detailed Implementation
[0019] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0020] The structure of the present invention will now be described in detail with reference to the accompanying drawings.
[0021] Example 1
[0022] like Figures 1 to 6As shown in the figure, the swing mold bottom fixture with integrated anti-deviation structure provided by the embodiment of the present invention includes a base 1, a placement seat 3 is fixedly installed in the middle of the upper surface of the base 1, and positioning blocks 4 are fixedly installed on both sides of the upper surface. The placement seat 3 is provided with a plurality of through holes 31, and mounting holes 32 are provided at the four corners of the placement seat 3. A limiting threaded sleeve 5 is provided in the mounting hole 32. An adjustment mechanism 2 is provided at the upper end of the limiting threaded sleeve 5. The adjustment mechanism 2 includes a threaded rod 21, which is threadedly connected to the limiting threaded sleeve 5. A rotating rod 22 is provided at the upper end of the threaded rod 21, and a pressure rod 6 is hinged to the rotating rod 22.
[0023] Furthermore, the bottom of the limiting threaded sleeve 5 is fixedly connected to the base 1, and the limiting threaded sleeve 5 matches the standardized positioning hole at the bottom of the target mold.
[0024] The limiting threaded sleeve 5, as a basic component fixed on the base 1, has two main functions: first, its outer cylindrical surface at the top can match the standardized positioning hole at the bottom of the target mold for initial positioning; second, its internal thread and the threaded rod 21 form a helical pair. By rotating the rotating rod 22 to drive the threaded rod 21 to rotate, it can make it move up and down in a helical motion relative to the fixed limiting threaded sleeve 5, thereby adjusting the height of the pressure rod 6.
[0025] Furthermore, the threaded rod 21 has an installation groove 211 at its top end, and a short spline hole 212 at the top end of the installation groove 211. A spring 29 and a telescopic rod 210 are fixedly installed in the installation groove 211. The spring 29 is sleeved on the telescopic rod 210. A baffle 28 is fixedly connected to the upper end of the spring 29 and the telescopic rod 210. A short spline rod 27 is fixedly connected to the upper surface of the baffle 28. The short spline rod 27 is slidably inserted into the short spline hole 212.
[0026] Spring 29 provides upward elastic force to short spline rod 27 through baffle 28, so that it is inserted into short spline hole 212 in its natural state. When subjected to downward pressure, short spline rod 27 can overcome the elastic force of spring 29 and retract into mounting groove 211, forming a resettable elastic spline connection assembly, providing an interface that can be engaged and disengaged for subsequent transmission connection with rotating rod 22.
[0027] Furthermore, the top of the threaded rod 21 is rotatably connected to the bottom of the rotating rod 22. A long spline hole 213 is provided through the rotating rod 22. The long spline hole 213 is adapted to the short spline hole 212. A long spline rod 26 is slidably inserted into the long spline hole 213. The bottom of the long spline rod 26 can be inserted into the short spline hole 212. Several anti-slip grooves 25 are provided on the outer circumference of the upper end of the rotating rod 22. A placement groove 23 is provided on the outer circumference of the lower end. A groove 24 is provided at the bottom of the placement groove 23. The pressure rod 6 is hinged in the placement groove 23.
[0028] When it is necessary to move the pressure rod 6 downward to press it against the target mold, the long spline rod 26 is pressed down, and its bottom pushes the short spline rod 27 down and finally inserts it into the empty short spline hole 212. When rotating the rotating rod 22, the threaded rod 21 can be driven to rotate synchronously. Through the threaded engagement between the threaded rod 21 and the limiting threaded sleeve 5, the pressure rod 6 is lowered and pushed outward from the groove 24 to unfold the pressure rod 6 until the pressure rod 6 presses against the target mold. After the operation is completed and the long spline rod 26 is released, the spring 29 pushes the short spline rod 27 up, thereby pushing the long spline rod 26 out of the short spline hole 212, and the transmission chain is disconnected.
[0029] By inserting and separating the spline rod, the state switching between rigid transmission during operation and motion decoupling during non-operation is realized. In the non-operation state, the rotating rod 22 and the threaded rod 21 can rotate freely relative to each other. Even if the rotating rod 22 is accidentally touched, it will not cause the threaded rod 21 to rotate, which fundamentally avoids the loosening of the pressure rod 6 due to accidental contact and improves safety and reliability.
[0030] Specifically, the threaded rod 21 includes a main body and a cover. The cover is fixedly connected to the upper end of the main body, the mounting groove 211 is located at the upper end of the main body, and the 212 is located in the cover. This configuration allows for the assembly of the baffle 28, spring 29, and telescopic rod 210.
[0031] Working principle of Embodiment 1 of the present invention: First, place the target mold on the placement base 3, align its standardized positioning hole with the fixed limiting threaded sleeve 5, and complete the initial precise positioning. Then, perform the anti-deviation locking operation: the operator presses down the long spline rod 26, inserting it into the short spline hole 212 at the top of the threaded rod 21, thereby locking the spline transmission connection between the rotating rod 22 and the threaded rod 21. At this time, rotating the rotating rod 22 will drive the threaded rod 21 to rotate within the limiting threaded sleeve 5 and change to a linear downward motion. The descending threaded rod 21 drives the pressure rod 6, which is hinged to it, to move downward. When the bottom of the pressure rod 6 approaches the surface of the target mold, the pressure rod 6 is unfolded outward, and the pressure rod 6 continues to move downward until the unfolded pressure rod 6 is firmly pressed against the surface of the target mold, realizing the secondary tightening of the mold and effectively preventing deviation. After locking is completed, the long spline rod 26 is released, and the transmission connection is automatically released under the action of the spring 29. The rotating rod 22 enters the free-spinning state, effectively preventing subsequent accidental contact that could cause loosening.
[0032] In summary, this integrated anti-deviation structure swing mold bottom fixture achieves a state switching between rigid transmission during operation and motion decoupling during non-operation by inserting and separating the spline rod. In the non-operation state, the rotating rod 22 and the threaded rod 21 can rotate freely relative to each other. Even if the rotating rod 22 is accidentally touched, it will not cause the threaded rod 21 to rotate, fundamentally avoiding the loosening of the pressure rod 6 due to accidental contact, thus improving safety and reliability.
[0033] Example 2
[0034] Based on Example 1, the following settings are also made: See Figures 1-9 The long spline rod 26 has a vertically arranged slide rail 7 on its side. Two symmetrically arranged limiting strips 8 are fixedly connected to the outside of the slide rail 7, and there is a gap channel 9 between the two limiting strips 8. The upper end of the limiting strip 8 has a locking interface 10, which is part of the slide rail 7. The bottom of the placement groove 23 has a limiting hole 11. The bottom of the pressure rod 6 is fixedly connected to a limiting rod 12. The end of the limiting rod 12 is fixedly connected to a locking protrusion 13, which can be locked into the locking interface 10. The width of the limiting rod 12 is smaller than the width of the gap channel 9.
[0035] With this setting, during rotation, when the long spline rod 26 is inserted into the short spline hole 212, the pressure rod 6 can be manually positioned horizontally. At this time, the pressure rod 6 presses against the upper wall of the groove 24 without exceeding the set value, and the locking protrusion 13 engages with the locking interface 10. The lower side of the locking protrusion 13 and the upper end of the limiting strip 8 are in contact. On the one hand, the threaded rod 21 can be rotated by moving the pressure rod 6; on the other hand, it can prevent the long spline rod 26 from moving upward and disengaging from the short spline hole 212. It is not necessary to hold the long spline rod 26 with another hand, thus enabling one-handed operation and facilitating the operation of the target mold with the other hand. When the pressure rod 6 presses against the target mold and the pressing force reaches the set value, the pressure rod 6 will tilt slightly upward, so that the locking protrusion 13 enters the slide 7, and the diameter of the limiting rod 12 is smaller than the width of the gap channel 9. At this time, the long spline rod 26 will automatically rise. This design also prevents the long spline rod 26 from being lost, because after the long spline rod 26 moves upward to a certain limit, the locking protrusion 13 will contact the bottom of the slide rail 7, thereby preventing the long spline rod 26 from rising further and thus preventing it from falling off.
[0036] It should be noted that the inventor considered the following solutions during the design process: either setting only the limiting rod 12 to tighten the long spline rod 26, or providing a slot (not shown in the figure) on the surface of the long spline rod 26 so that the limiting rod 12 can be engaged in the slot. However, this solution has a drawback: although it can fix the position of the long spline rod 26, when the pressure rod 6 and the mold are pressed together, the limiting rod 12 cannot disengage from the long spline rod 26, and therefore cannot disengage the long spline rod 26 from the short spline hole 212, thus rendering the entire design ineffective. Therefore, the inventor creatively designed the above-mentioned mechanism to solve the above problems, achieving the effects of single-handed operation and preventing the long spline rod 26 from disengaging.
[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
