According to one embodiment of the present application, as shown in fig. 1-4, the self-contact type slider device of the present embodiment includes a slider frame 1 and a plurality of elastic supports provided on the slider frame 1.
Referring to fig. 1 and 2, the slider frame 1 is a cuboid, four sides on the cuboid are provided with a plurality of through holes, each through hole is used for fixing an elastic supporting body, two other sides on the cuboid are respectively provided with a synchronous belt connecting plate 7, and the synchronous belt connecting plates 7 are connected with synchronous belts to realize traction driving of the slider frame 1.
Referring to fig. 3 and 4, the elastic support body includes a locking bolt 6, a bearing support 4, a spring 5, and a rolling bearing 3, the bearing support 4 passes through the through hole, the rolling bearing 3 is fixed on one end of the bearing support 4 outside the slider frame 1, and the rolling bearing 3 is supported, achieving close contact of the rolling bearing 3 with the inner wall of the guide rail 8. The other end of the bearing support 4 is sleeved with a spring 5, and the bearing support 4 is fixed on the sliding block framework 1 through a locking bolt 6. The spring 5 is used for relieving stress between the rolling bearing 3 and the guide rail 8 and has the function of buffering and damping; meanwhile, the extension length of the rolling bearings 3 can be adjusted by adjusting the locking bolts 6, so that each rolling bearing 3 is tightly attached to the inner wall of the guide rail 8, and further stable running of the traction drive of the sliding block is ensured.
According to an embodiment of the application, referring to fig. 2, 3 and 4, a support plate 2 is provided on the slider frame 1 for supporting the moving mold.
