Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary positioning components for mold assembly, and specifically relates to a mold assembly positioning structure. Background Technology

[0002] Common molds include stamping molds, injection molds, and die-casting molds. During the assembly of the upper and lower mold bases, it is necessary to ensure precise assembly between the punch and the die. Therefore, a positioning structure is required. Traditional positioning methods mainly rely on guide pillars and guide sleeves. The smooth opening and closing of the mold is ensured by the linear positioning of the guide pillars and guide sleeves.

[0003] During the long-term assembly process of the mold, there may be a large horizontal positional deviation between the upper and lower mold bases. The guide bushing does not have a limiting design on the outside, and the guide bushing may be offset, causing the guide post to directly hit the inner wall of the guide bushing. Friction will occur between the guide bushing and the guide post, and may even damage the outer surface of the guide post and the inner surface of the guide bushing. Small impurities are prone to adhere to the outer surface of the guide post and the inner surface of the guide bushing, which will aggravate wear and cause deviation or offset between the guide bushing and the guide post, further increasing wear. This will prevent the guide post from being smoothly poured into the guide bushing, which requires improvement.

[0004] Existing guide sleeve and guide post positioning molds have the problem of not having a design to prevent offset when limiting the position of the guide sleeve. To address this, this application proposes a mold assembly positioning structure. Utility Model Content

The connecting rod 32 is welded to the fixed outer ring 31. The fixing block 33 is fixed to the connecting rod 32 by screws. The anti-skew block 34 is welded to the fixing block 33. The anti-skew block 34 penetrates the top cover 42 and is inserted into the interior of the positioning block 41, and is symmetrically distributed. The anti-skew block 34 is limited by the positioning block 41, preventing the anti-skew block 34 from skewing with the fixing block 33, the connecting rod 32, and the fixing outer ring 31, thereby limiting the guide sleeve cylinder 2 and preventing deviation or offset of the guide sleeve cylinder 2; the limiting components include the positioning block 41 and the top cover 42 fixedly connected by screws, the partition plate 43 embedded inside the positioning block 41, and the rolling element 44 installed inside the positioning block 41. The positioning block 41 and the top cover 42 limit the anti-skew block 34 and prevent the anti-skew block 34 from skewing. The rolling element 44 4. The anti-skew block 34 rolls into contact with the anti-skew block 34, reducing the friction force on the anti-skew block 34; the positioning component includes a stabilizing rod 5 whose top end is fixedly connected to the end of the connecting rod 32, and a positioning cylinder 6 whose top end is fixedly connected to one end of the stabilizing rod 5. The positioning cylinder 6 is provided with ball bearings 9 inside. The stabilizing rod 5 and the connecting rod 32 are fixed by bolts. The positioning cylinder 6 is sleeved on the outside of the guide post 1. The positioning cylinder 6 is limited by the guide post 1, thereby limiting the stabilizing rod 5, the connecting rod 32, the fixed outer ring 31, and the guide sleeve cylinder 2, and preventing the guide sleeve cylinder 2 from shifting.

[0029] In this embodiment, the positioning block 41 has a recessed movable cavity on the surface facing the top cover 42. The partition plate 43 divides the movable cavity into cavity A and cavity B. The rolling body 44 is located in cavity B. The bottom end of the anti-skew block 34 is inserted into cavity A. The anti-skew block 34 can be inserted into the interior of the positioning block 41 so that the positioning block 41 limits the anti-skew block 34.

[0030] In this embodiment, the anti-skew block 34 rolls in contact with the partition plate 43, and the surface of the anti-skew block 34 is tangent to the surface of the partition plate 43, thereby reducing the frictional force on the anti-skew block 34.

[0031] In this embodiment, the center lines of the fixed outer ring 31 and the guide sleeve cylinder 2 are on the same vertical line, the center line of the connecting rod 32 is perpendicular to the center line of the fixed outer ring 31, the height of the guide sleeve cylinder 2 moving down is the same as the depth of the anti-skew block 34 moving into the positioning block 41, and the vertical distance of the guide sleeve cylinder 2 moving is the same as the vertical distance of the anti-skew block 34 moving.

[0032] In this embodiment, the centerline of the positioning cylinder 6 overlaps with the centerline of the guide post 1. The ball bearing 9 inside the positioning cylinder 6 rolls in contact with the guide post 1. The ball bearing 9 is tangent to the guide post 1. The friction between the ball bearing 9 and the guide post 1 is small and does not affect the vertical movement of the positioning cylinder 6 on the outside of the guide post 1.

[0033] In this embodiment, connecting rings 7 are fixed to the top and bottom of the positioning cylinder 6 by screws. A wiping ring 8 is fixed to the inner surface of the connecting ring 7 by adhesive. The inner diameter of the wiping ring 8 is the same as the outer diameter of the guide post 1. The diameter of the positioning cylinder 6 is the same as the diameter of the guide sleeve cylinder 2. The surfaces of the positioning cylinder 6, the connecting ring 7, and the wiping ring 8 are flush. During the vertical movement of the guide sleeve cylinder 2, the wiping ring 8 plays the role of rough sealing and wiping impurities on the surface of the guide post 1. The connecting ring 7 has a screw hole b that extends into the positioning cylinder 6, which facilitates the screw fixing of the connecting ring 7 and the positioning cylinder 6.

[0034] Working principle and usage process of this utility model:

[0035] During the mold closing process of the upper mold base and the lower mold base, the guide sleeve cylinder 2 moves outside the guide pillar 1, and the guide pillar 1 is guided into the interior of the guide sleeve cylinder 2, thereby limiting the guide sleeve cylinder 2.

[0036] The anti-skewing block 34, the fixing block 33, the connecting rod 32, and the fixing outer ring 31 form an anti-skewing whole. The positioning block 41 is fixedly connected to the lower mold base. When the positioning block 41 is in a fixed state, the whole moves synchronously with the guide sleeve cylinder 2.

[0037] When the guide sleeve cylinder 2 moves down, the entire structure moves down, and the anti-deviation block 34 is inserted into the interior of the positioning block 41, so that the positioning block 41 restricts the anti-deviation block 34.

[0038] Under the limiting effect of the positioning block 41 and the top cover 42, the guide sleeve cylinder 2 is limited, so as to prevent the guide sleeve cylinder 2 from deviating or shifting.

[0039] The positioning cylinder 6 is sleeved on the outside of the guide post 1. The positioning cylinder 6 is limited by the guide post 1, which in turn limits the stabilizing rod 5, the connecting rod 32, the fixing outer ring 31, and the guide sleeve cylinder 2, thus preventing the guide sleeve cylinder 2 from shifting.

[0040] During the vertical movement of the guide sleeve cylinder 2, the wiping rubber ring 8 serves to provide a rough seal and wipe away impurities from the surface of the guide column 1.

[0041] In summary: The guide sleeve and guide post positioning structure of this application has an anti-deviation design that limits the position of the guide sleeve. The anti-deviation block 34, the fixing block 33, the connecting rod 32, and the fixing outer ring 31 form an anti-deviation whole. Under the limiting effect of the positioning block 41 and the top cover 42, the above-mentioned whole and the guide sleeve cylinder 2 are limited, so as to avoid deviation or displacement of the guide sleeve cylinder 2.
