Technical Field

[0001] The utility model relates to the field of wax molds, and specifically relates to a roller-type inclined pressure block structure that is convenient for replacement. Background Art

[0002] In the design of molds, inclined draw blocks are commonly used, and all of them use flat compression springs to achieve automation. However, it is easy to wear due to flat friction compression, so it also leaves drawbacks for the accuracy of the mold in the later stage.

[0003] Currently, in order to ensure the accuracy of flat friction and reduce wear, the method of using rollers or roller sleeves is mostly adopted. By replacing sliding friction with rolling friction, wear is reduced and accuracy is improved. However, since the rollers or roller sleeves still need to be replaced regularly in the later stage, and most of the rollers or roller sleeves are located inside the inclined draw block, it is quite troublesome to maintain and replace them in the later stage.

The length of the roll sleeve 8 is slightly less than the sum of the lengths of the circular grooves on the corresponding left inclined block 2 and the right inclined block 1. The outer diameter of the roll sleeve 8 is slightly less than the inner diameter of the circular groove. The distance from the inclined surface to the center of the roll sleeve 8 is slightly less than the radius of the roll sleeve 8, and the roll sleeve 8 can protrude from the inclined surface through the communication groove 7;

[0036] The left inclined block 2 and the right inclined block 1 are also provided with corresponding connecting holes 3. The left inclined block 2 and the right inclined block 1 can be connected together through connecting bolts, and then the roller sleeve 8 is restricted in the circular groove between the left inclined block 2 and the right inclined block 1.

[0037] For the convenience of installation, the circular grooves penetrate through the left inclined block 2 and the right inclined block 1 respectively. On the left side of the left inclined block 2 and the right side of the right inclined block 1, large-diameter holes are provided at the positions corresponding to the circular groove holes. The diameter of the large-diameter holes is larger than the diameter of the circular groove. One end of each of the left roller shaft 9 and the right roller shaft 10 is provided with a boss 4. The boss 4 can be matched with the large-diameter hole. The length of the boss 4 is equal to the depth of the large-diameter hole, and the diameter of the boss 4 is equal to the diameter of the large-diameter hole. The left roller shaft 9 and the right roller shaft 10 with the boss 4 can be directly installed from the end of the large-diameter hole.

[0038] To prevent the left roller shaft 9 and the right roller shaft 10 from detaching from the end of the large-diameter hole, the other end of the left roller shaft 9 of the present utility model is provided with a threaded hole 11, and the other end of the right roller shaft 10 is provided with a threaded post 12; or, the other end of the right roller shaft 10 is provided with a threaded hole 11, and the other end of the left roller shaft 9 is provided with a threaded post 12; the threaded post 12 can be screwed with the threaded hole 11, and internal hexagonal holes are provided at the end parts of the bosses 4 of the left roller shaft 9 and the right roller shaft 10, which is convenient for realizing the connection of the left roller shaft 9 and the right roller shaft 10.

[0041] The specific disassembly and assembly process of the present utility model:

[0042] First, the left roller shaft 9 and the right roller shaft 10 are respectively installed on the left inclined block 2 and the right inclined block 1. Before the left inclined block 2 and the right inclined block 1 are combined, both ends of the roller sleeve 8 are respectively sleeved on the left roller shaft 9 and the right roller shaft 10, and then the left inclined block 2 and the right inclined block 1 are combined. At the same time, the left roller shaft 9 or the right roller shaft 10 is rotated so that the left roller shaft 9 and the right roller shaft 10 are connected through the threaded post 12 and the threaded hole 11. Finally, the left inclined block 2 and the right inclined block 1 are connected by using a connecting bolt to pass through the connecting hole 3.

[0043] When disassembling, the connecting bolt needs to be disassembled first, and then the left roller shaft 9 or the right roller shaft 10 is rotated to separate the left roller shaft 9 and the right roller shaft 10, so that the left inclined block 2 and the right inclined block 1 can be separated. At this time, the roller sleeve 8 can be taken off from the left roller shaft 9 and the right roller shaft 10.

[0044] During the disassembly process, the disassembly and assembly at the position with high assembly accuracy are reduced, and thus the original assembly accuracy is always ensured.
