Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a stable guide post structure. Background Technology

[0002] As a core guiding component of the mold, the guide pillar's primary function is to ensure precise guidance and positioning when the moving and fixed molds close, preventing molding defects caused by misalignment. Simultaneously, the guide pillar rigidly supports the moving and fixed mold plates, ensuring stable mold operation under high-speed opening and closing and load variations.

[0003] However, the widely used guide post mechanism currently has potential hidden dangers: its buffer system is equipped with only a single spring structure, which leads to excessive stress concentration under high-frequency impact loads. During long-term operation, the spring is prone to failure due to insufficient fatigue resistance, causing the guide post to instantly lose its buffer protection and auxiliary support capabilities, which in turn induces a chain of failures such as mold jamming, guide post surface scratches, and even template deformation. Utility Model Content

[0004] Therefore, it is necessary to provide a stable guide post structure to solve the technical problems existing in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A stable guide post structure includes: a base plate, a mounting plate, a first elastic element, an elastic component, a first guide sleeve, a second guide sleeve, and a top plate. The mounting plate is disposed at the top of the base plate, and a limiting cylinder and a guide post are disposed at the top of the mounting plate. The guide post is located inside the limiting cylinder. The inner surfaces of the first elastic element, the first guide sleeve, the second guide sleeve, and the top plate are all sleeved on the outer surface of the guide post. A first end of the first elastic element is connected to the top of the mounting plate, and a second end of the first elastic element is connected to the bottom end of the first guide sleeve. The outer surface of the first guide sleeve slides in cooperation with the inner surface of the limiting cylinder. A plurality of limiting posts are arranged around the top of the first guide sleeve, and a plurality of movable holes are opened around the bottom of the second guide sleeve. Each movable hole corresponds one-to-one with the position of a limiting post. The limiting post is installed in the movable hole through the elastic component. The top plate is connected to the top of the second guide sleeve.

[0007] Furthermore, the top end of the first guide sleeve is also surrounded by a plurality of guide rods, and the bottom end of the second guide sleeve is surrounded by a plurality of guide holes, each guide hole corresponding to the position of one of the guide rods.

[0008] Furthermore, the inner surface of the limiting cylinder is provided with multiple guide grooves, and the outer surface of the first guide sleeve is surrounded by multiple guide blocks, each of the guide blocks being slidably disposed in one of the guide grooves.

[0009] Furthermore, the guide block has an arc-shaped surface on the side facing the guide groove, and the horizontal cross-sectional shape of the guide groove corresponds to the arc-shaped surface.

[0010] Furthermore, a plurality of heat dissipation holes are spaced apart on one side of the guide groove, and the heat dissipation holes are provided through the outer surface of the limiting cylinder.

[0011] Furthermore, the stable guide post structure also includes multiple fasteners, the top of the mounting plate has multiple through holes, the top of the base plate has multiple threaded holes, and each fastener passes through one of the through holes and connects to the side wall of one of the threaded holes.

[0012] Furthermore, the elastic component includes a plurality of spaced-apart second elastic elements, the second elastic elements being sleeved on the outer surface of the limiting post, the first end of the second elastic element being connected to the top end of the first guide sleeve, and the second end of the second elastic element being located inside the movable hole and movably abutting against the inner wall of the movable hole.

[0013] Furthermore, both the first elastic element and the second elastic element are springs.

[0014] The beneficial effects of this utility model are as follows: by setting a first elastic element, an elastic component, a first guide sleeve, and a second guide sleeve, when the top plate moves downward, the top plate drives the second guide sleeve to press down on the elastic component. The pressure is transmitted to the first guide sleeve through the elastic component, causing the second guide sleeve to move downward and press down on the first elastic element. The first elastic element and the elastic component simultaneously buffer the pressure when the top plate moves downward. The synergistic effect of the first elastic element and the elastic component can absorb vibration more evenly, thereby enabling the guide column to achieve precise guidance and stable support.

Detailed Implementation

[0021] Example 1

[0022] A stable guide post structure, such as Figures 2 to 4As shown, the system includes: a base plate 10, a mounting plate 20, a first elastic element 50, multiple second elastic elements 52, a first guide sleeve 60, a second guide sleeve 70, and a top plate 30. The mounting plate 20 is disposed at the top of the base plate 10. A limiting cylinder 40 and a guide post 62 are disposed at the top of the mounting plate 20. The guide post 62 is located inside the limiting cylinder 40. The inner surfaces of the first elastic element 50, the first guide sleeve 60, the second guide sleeve 70, and the top plate 30 are all fitted onto the outer surface of the guide post 62. The first end of the first elastic element 50 is connected to the top of the mounting plate 20, and the second end of the first elastic element 50 is connected to the bottom end of the first guide sleeve 60. The outer surface of the first guide sleeve 60 is connected to the limiting cylinder. The inner surface of the 40 slides together. The top end of the first guide sleeve 60 is surrounded by multiple limiting posts 61. The bottom end of the second guide sleeve 70 is surrounded by multiple movable holes 71. Each movable hole 71 corresponds to a limiting post 61. Multiple spaced second elastic elements 52 form an elastic component. The limiting posts 61 are fixedly or movably installed in the movable holes 71 through the elastic component. The second elastic elements 52 are sleeved on the outer surface of the limiting posts 61. The first end of the second elastic element 52 is connected to the top end of the first guide sleeve 60. The second end of the second elastic element 52 is located in the movable hole 71 and movably abuts against the inner wall of the movable hole 71. The top plate 30 is connected to the top end of the second guide sleeve 70. During use, as the mold opens and closes, the top plate 30 drives the second guide sleeve 70 to move up and down. Since the second guide sleeve 70 and the first guide sleeve 60 are indirectly connected by the first elastic element 50, when the second guide sleeve 70 moves downward, the inner wall of the movable cavity of the second guide sleeve 70 presses down on the second elastic element 52. Subsequently, the pressure can be transmitted to the first guide sleeve 60 through each of the second elastic elements 52, causing the first guide sleeve 60 to also move downward and press down on the first elastic element 50. Thus, the pressure of the top plate 30 moving downward can be buffered by the second elastic elements 52 and the first elastic element 50, so that the guide post structure can achieve precise guidance and stable support. When the top plate 30 retracts, it drives the second guide sleeve 70 to move upward. At this time, due to the release of pressure, the second elastic elements 52 and the first elastic element 50 undergo an elastic phase change recovery, causing the first guide sleeve 60 and the second guide sleeve 70 to return to their initial positions. Since each second elastic element 52 is sleeved on the outer surface of the limiting post 61, the limiting post 61 can restrict the movement direction of the second elastic element 52, ensuring that the movement direction of the second elastic element 52 is consistent with the movement direction of the second guide sleeve 70. When the first guide sleeve 60 moves up and down, the outer surface of the first guide sleeve 60 slides on the inner surface of the limiting cylinder 40. The limiting cylinder 40 can restrict the movement direction of the first guide sleeve 60, making the movement direction of the first guide sleeve 60 consistent with the movement direction of the second guide sleeve 70.

[0023] Preferably, the top end of the first guide sleeve 60 is further surrounded by a plurality of guide rods 62, and the bottom end of the second guide sleeve 70 is surrounded by a plurality of guide holes 72, each guide hole 72 corresponding to a guide rod 62. When the second guide sleeve 70 moves downward, each guide rod 62 moves within each guide hole 72. The guide rods 62 can restrict the direction of movement of the second guide sleeve 70, ensuring that the second guide sleeve 70 always moves in a vertical direction during its up-and-down movement, and preventing the second guide sleeve 70 from shifting laterally or tilting.

[0024] Preferably, the inner surface of the limiting cylinder 40 is provided with multiple guide grooves 41, and the outer surface of the first guide sleeve 60 is surrounded by multiple guide blocks 63, each guide block 63 being slidably disposed within a guide groove 41. By utilizing the cooperation between the guide grooves 41 and the guide blocks 63, the movement direction of the first guide sleeve 60 can be restricted, ensuring that the movement direction of the first guide sleeve 60 is consistent with that of the second guide sleeve 70. Furthermore, by providing the guide blocks 63 and guide grooves 41, the resistance encountered by the first guide sleeve 60 when moving on the limiting cylinder 40 can be reduced, resulting in smooth movement of the first guide sleeve 60.

[0025] Preferably, a plurality of heat dissipation holes 42 are spaced apart on one side of the guide groove 41, and the heat dissipation holes 42 penetrate the outer surface of the limiting cylinder 40. The heat dissipation holes 42 can effectively dissipate the frictional heat generated by the guide block 63 and the guide groove 41 during relative sliding, thereby reducing the temperature rise of the contact surface and preventing the first guide sleeve 60 from deforming due to overheating, which would affect the normal use of the guide post.

[0026] Preferably, the stable guide post structure further includes multiple fasteners 80. The top of the mounting plate 20 has multiple through holes 22, and the top of the base plate 10 has multiple threaded holes 11. Each fastener 80 passes through a through hole 22 and connects to the side wall of a threaded hole 11. The fasteners 80 secure the mounting plate 20 to the base plate 10, ensuring the stability of the entire guide post structure and increasing its operational stability. The fasteners 80 are bolts.

[0027] Example 2

[0028] Unlike Example 1, see [link to example]. Figure 1 and Figure 4 The guide block 63 has an arc-shaped surface 631 on the side facing the guide groove 41, and the horizontal cross-sectional shape of the guide groove 41 corresponds to the arc-shaped surface 631. The arc-shaped surface 631 can reduce the sliding resistance of the guide block 63 in the guide groove 41, making the movement of the guide block 63 in the guide groove 41 smoother.

[0029] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0031] Unlike Example 1, see [link to example]. Figure 2 and Figure 3 Both the first elastic element 50 and the second elastic element 52 are springs.
