Description

Technical Field

[0001] This utility model belongs to the technical field of molds, specifically relating to a reusable guide post structure. Background Technology

[0002] During the mold closing process, guide pillar mechanisms are often used in mold design to ensure the mold's guiding and positioning requirements and to prevent damage to the parting surface.

[0003] The existing guide post and guide sleeve are mostly made by directly sliding the guide post and guide sleeve together. After a long period of operation, the lubricating oil will be lost, which will cause the guide post to wear.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0005] The existing structure cannot be reused, and the guide rod needs to be disassembled before lubricating oil can be added. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a reusable guide post structure. By optimizing the guide post structure, the problem of needing to disassemble the guide rod to add lubricating oil is solved.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A reusable guide post structure includes a guide rod for engaging with a guide sleeve; a connecting plate disposed at the end of the guide rod; a first groove is provided on the surface of the guide rod near the connecting plate, the first groove surrounding the circumference of the guide rod, and multiple through holes are provided at the bottom of the first groove; multiple conduits communicating with the through holes are disposed inside the guide rod; a manifold is disposed inside the connecting plate, one end of the manifold being disposed on the side of the connecting plate, and the other end of the manifold communicating with the conduits; a second groove is provided on the surface of the guide rod away from the connecting plate, and multiple guide grooves are provided between the first groove and the second groove, the guide grooves being disposed along the length direction of the guide rod.

[0009] In some possible implementations, a plurality of the through holes are spaced apart along the first groove, and a plurality of the guide grooves are spaced apart around the guide rod.

[0010] In some possible implementations, a first transition portion is provided between the sidewall of the first groove and the surface of the guide rod, and a second transition portion is provided between the second groove and the surface of the guide rod, wherein both the first transition portion and the second transition portion are arc-shaped.

[0011] In some possible implementations, the number of guide grooves is 6 to 7, and the number of through holes is 6 to 7.

[0012] In some possible implementations, the outer diameter of the guide rod is smaller than the outer diameter of the connecting plate.

[0013] In some possible implementations, both the guide rod and the connecting plate are made of alloy material.

[0014] One of the above technical solutions has the following beneficial effects:

[0015] This invention optimizes the guide post structure by designing a first groove on the surface of the guide rod. Multiple through holes are designed at the bottom of the first groove, connecting to a conduit and a manifold. Lubricating oil can be directly delivered to the first groove through the manifold, conduit, and through the through holes. The lubricating oil in the first groove is then guided by gravity through multiple guide grooves into a second groove, thus delivering the lubricating oil to the gap between the guide rod and the guide sleeve. This eliminates the need to disassemble the guide rod to add lubricating oil, allowing for repeated use of the guide rod and improving production efficiency. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0035] Example 1

[0036] Since the existing structure cannot be reused, the guide rod needs to be disassembled before lubricating oil can be added.

[0037] like Figures 1-3As shown, the reusable guide post structure of this utility model includes a guide rod 1 for cooperating with a guide sleeve; a connecting plate 2 disposed at the end of the guide rod 1; a first groove 3 is provided on the surface of the guide rod 1 near the connecting plate 2, the first groove 3 is arranged around the guide rod 1, and a plurality of through holes 4 are provided at the bottom of the first groove 3; a plurality of conduits 5 communicating with the through holes 4 are provided inside the guide rod 1; a manifold 6 is provided inside the connecting plate 2, one end of the manifold 6 is disposed on the side of the connecting plate 2, and the other end of the manifold 6 is connected to the conduits 5; a second groove 7 is provided on the surface of the guide rod away from the connecting plate 2, and a plurality of guide grooves 8 are provided between the first groove 3 and the second groove 7, the guide grooves 8 being arranged along the length direction of the guide rod 1. This invention optimizes the guide post structure by designing a first groove 3 on the surface of the guide rod 1. Multiple through holes 4 are designed at the bottom of the first groove 3, connecting to the conduit 5 and manifold 6. Lubricating oil can be directly delivered to the first groove 3 via the manifold 6, conduit 5, and through holes 4. The lubricating oil in the first groove 3 is then guided by gravity through multiple guide grooves 8 into the second groove 7, thus delivering the lubricating oil to the gap between the guide rod 1 and the guide sleeve. This eliminates the need to disassemble the guide rod, solving the problem of having to remove it to add lubricating oil. It also facilitates the reuse of the guide rod and improves production efficiency.

[0038] It should be noted that one end of the manifold 6 is exposed on the side of the connecting plate 2. This end can be directly connected to the lubricating oil pump. When additional lubricating oil is needed, the lubricating oil pump is turned on, and the lubricating oil is delivered through the manifold 6, the conduit 5, and the through hole 4 to the gap between the guide rod 1 and the guide sleeve. Multiple conduits 5 can be embedded in the side wall of the guide rod 1. The connecting plate 2 is designed as a hollow structure, and the manifold 6 is an L-shaped structure located inside the connecting plate 2. One end of the manifold 6 is connected to each conduit 5 through a distributor, and the other end of the manifold 6 is located on the side of the connecting plate 2, where an interface for cooperating with the lubricating oil pump is installed. The guide groove 8 connects the first groove 3 and the second groove 7. The lubricating oil in the first groove 3 flows along the guide groove 8 to the second groove 7. The guide groove 8 covers most of the surface area of ​​the guide rod 1, enabling the delivery of lubricating oil to the sliding area between the guide rod 1 and the guide sleeve.

[0039] In the reusable guide post structure according to this utility model, multiple through holes 4 are spaced apart along the first groove 3, so that the lubricant is evenly distributed at each position of the first groove 3, and multiple guide grooves 8 are spaced around the guide rod 1. Specifically, the lubricant in the first groove 3 flows along the guide groove 8 to the second groove 7. The guide groove 8 covers the circumferential surface area of ​​the guide rod 1, and the circumferential surface of the guide rod 1 corresponds to the gap between the guide rod 1 and the guide sleeve, which can deliver the lubricant to the area where the guide rod 1 and the guide sleeve slide together, avoiding the lubricant overflowing from the guide sleeve and causing waste. Among them, the guide groove 8 extends downward along the length direction of the guide rod 1, and the guide groove 8 is inclined at a certain angle, which helps to increase the length of the guide groove 8 on the surface of the guide rod 1, thereby increasing the length of the lubricant path on the surface of the guide rod 1 and improving the overall lubrication effect.

[0040] In the reusable guide post structure according to the present invention, a first transition portion 9 is provided between the side wall of the first groove 3 and the surface of the guide rod 1, and a second transition portion 10 is provided between the second groove 7 and the surface of the guide rod 1. Both the first transition portion 9 and the second transition portion 10 are arc-shaped, which can improve the reliability of the flow of lubricating fluid between the first groove 3 and the second groove 7, so that the lubricating fluid flows smoothly in the guide groove 8 and delivers the lubricating oil to the area where the guide rod 1 and the guide sleeve slide together.

[0041] The working principle of this utility model is as follows:

[0042] This invention optimizes the guide post structure by designing a first groove 3 on the surface of the guide rod 1. Multiple through holes 4 are designed at the bottom of the first groove 3, connecting to the conduit 5 and manifold 6. Lubricating oil can be directly delivered to the first groove 3 via the manifold 6, conduit 5, and through holes 4. The lubricating oil in the first groove 3 is then guided by gravity through multiple guide grooves 8 into the second groove 7, thus delivering the lubricating oil to the gap between the guide rod 1 and the guide sleeve. This eliminates the need to disassemble the guide rod, solving the problem of having to remove it to add lubricating oil. It also facilitates the reuse of the guide rod and improves production efficiency.

[0043] Example 2

[0044] Unlike Embodiment 1, this embodiment has 6 to 7 guide grooves 8 and 6 to 7 through holes 4. However, this utility model is not limited to this. The number of guide grooves 8 and through holes 4 can be adjusted according to the actual size of the guide post. The outer diameter of the guide rod 1 is smaller than the outer diameter of the connecting plate 2 to prevent the guide sleeve from coming out of the guide rod 1.

[0045] The other structures are the same as in Embodiment 1, and will not be described again here.

[0046] Example 3

[0047] Unlike Embodiment 1, the guide rod 1 and connecting plate 2 in this embodiment are both made of alloy material, preferably copper-carbon alloy, which helps to reduce the risk of scratching.

[0048] The other structures are the same as in Embodiment 1, and will not be described again here.

[0049] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
