Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of accessory assembly, especially a buffer relaxation device. BACKGROUND

[0002] The guide sleeve and the guide pillar are a mold accessory used in cooperation to play a guiding role. In the traditional guide pillar guide sleeve guiding system, although its design has been widely used in many industrial applications, there are still some defects. The traditional guide pillar guide sleeve adopts rigid guiding setting, which means that they lack flexibility in design and cannot compensate for the positioning deviation caused by manufacturing errors, wear or improper installation. This rigid design is easy to cause mold damage during mold clamping. When the positioning deviation occurs between the guide sleeve and the guide pillar, the rigid guide cannot be adjusted, and the deviation may directly cause the mold to be scrapped during mold clamping. This not only increases the production cost, but also affects the production efficiency. When in use, the structure needs to be processed and improved again, which increases the process and reduces the work efficiency. Therefore, the present application provides a buffer relaxation device to solve the above technical problems. SUMMARY

[0006] The structure provides a high-efficiency and reliable mechanism for adjusting the tightness and ensuring smooth mold opening and closing operation through the combination of the adjusting plate, the top plate, the guide positioning rod, the connecting plate and the support plate. The clearance groove on the support plate provides additional space for the auxiliary guide positioning rod, and at the same time, disperses the force exerted by the guide positioning rod, avoids local stress concentration, and reduces the risk of deformation or damage caused by long-term use. The structure improves the rigid guide setting of the traditional guide pillar and guide sleeve, adopts the mold opening and closing mode to provide additional space, reduces the damage caused by the positioning deviation of the guide positioning rod and the guide hole when closing the mold, and when the guide positioning rod and the guide hole have positioning deviation, the rigid guide of the traditional guide pillar and guide sleeve cannot be adjusted, and the size of the deviation may directly cause the mold to be scrapped when closing the mold.

[0007] The structure is preliminarily aligned by the guide hole and the guide cone, and then the guide hole is positioned to limit the outer surface of the guide positioning rod for secondary alignment, so that it maintains a coaxial structure to facilitate mold closing.

The clamping block has an anchor-shaped structure, and the guide positioning rod has a clamping groove installed in the clamping block. The clamping block has an anchor-shaped structure and is limited to the surface of the guide positioning rod after being installed in the clamping groove, thereby preventing the guide positioning rod from continuously penetrating into the interior of the guide hole.

[0009] Further, the surface of the guide positioning rod is provided with a connecting frame and a limiting block, and one end of the limiting block faces the surface of the fixed block. This structure can limit the movement of the guide positioning rod during movement, prevent the guide positioning rod from exceeding the predetermined travel range, and avoid damage or failure caused by excessive stretching.

[0011] Further, the surface of the supporting plate is provided with a buffer cylinder, one end of the buffer cylinder is provided with a buffer block, and the buffer block is symmetrically installed at both ends of the buffer cylinder; this structure ensures that the impact force is uniformly distributed on both sides of the buffer cylinder, avoids local stress concentration, reduces the damage risk caused by impact, and the symmetrically installed buffer block can provide dynamic balance during movement, reduce vibration and shaking, ensure the stability of equipment operation, and improve the accuracy of operation.

[0012] Further, one end of the connecting plate is provided with a pad plate for reducing the vibration force, one end of the pad plate is connected with a limiting plate, and the pad plate is located between the connecting plate and the limiting plate; the installation position of the pad plate plays a role in uniformly distributing stress, avoids local stress concentration, cooperates with the local position limitation of the limiting plate, reduces the vibration force generated during mold closing, and thereby reduces the probability of scratching the inner surface of the air-avoiding groove when the guide positioning rod moves up or down.

[0013] Further, the guide positioning rod matrix is arranged on the surface of the top plate and movably connected with the top plate, the diameter of the air-avoiding groove is larger than the diameter of the guide positioning rod, and the structure of the guide positioning rod matrix arrangement can make the guide positioning rod more uniformly distribute the force, avoid local stress concentration and cause bending or deformation, in addition, the mold opening and closing orientation of the guide positioning rod is limited through the multi-point positioning mode, the accuracy of mold opening and closing is ensured, the larger diameter of the air-avoiding groove ensures that the guide positioning rod has sufficient movement space during movement, avoids the jamming phenomenon, and ensures the smoothness and stability of the guide positioning rod during upward movement or downward movement.
