[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figure 1~Figure 5As shown, a multi-directional combined slider includes a first slider 1, a first step groove 11 is provided on the first slider 1, two first fixed blocks 12 are fixedly connected to the first step groove 11 to form a first slide groove 13, and the second slider 2 is slidably connected to the first slide groove 13. The first driving mechanism adopts hydraulic drive or pneumatic drive, and the first driving mechanism includes a telescopic cylinder 14 and a telescopic rod 15, and the telescopic rod 15 is connected to the first slider 1 through a card slot. The second driving mechanism includes a second fixed block 21, the second fixed block 21 is fixedly connected to an inclined guide column 22, the second fixed block 21 is slidably connected to the second slider 2, the inclined guide column 22 is slidably connected to the second slider 2, the inclination direction of the inclined guide column 22 is consistent with the sliding direction of the second slider 2, and the second driving mechanism drives the second slider 2 to slide relative to the first slider 1, as shown in FIG. Figure 3 As shown, when the second fixed block 21 and the inclined guide column 22 move upward relative to the first slider 1, the second slider 2 slides to the left; when the second fixed block 21 and the inclined guide column 22 move downward relative to the first slider 1, the second slider 2 slides to the right. In this embodiment, the fixed block 21 is fixedly connected to the mother mold and moves synchronously with the mother mold. The third driving mechanism drives the third slider 3 and the fourth slider 4 to slide relative to the first slider 1. The third driving mechanism includes a third fixed block 31. The third fixed block 31 is fixedly connected to the first slider 1. The third connecting block 32 is provided with a third slide groove 321. The third fixed block 31 is slidably connected to the third connecting block 32 through the third slide groove 321. The T-slot connecting block 33 is fixedly connected to the third connecting block 32. The third slider 3 and the fourth slider 4 are slidably connected to the T-slot connecting block 33 respectively. The third connecting block 32 is threadedly connected to the resin shutter 34. The resin shutter 34 is used to sequentially drive the third connecting block 32 and the T-slot connecting block 33, and then drive the third slider 3 and the fourth slider 4 to slide relative to the first slider 1.

In this embodiment, the resin shutter 34 uses the machine signal male and female molds to open the mold. The resin shutter 34 generates a vacuum effect before opening the mold. When the mold is opened, the resin shutter 34 drives the connection block 32 to move.
