The positioning mechanism 300 includes a holder, an upper mold 330, a lower mold 340, a first driving cylinder 310, a second driving cylinder 351, a driving block 352, and a roller 500.

The upper mold 330 is located above the lower mold 340, and the upper mold 330 and the lower mold 340 are closed by moving the upper mold 330 downwards and moving the lower mold 340 upwards.

The lower die 340 is slidably connected to the support, specifically, the support includes a top plate 321, a guide post 322 and a bottom plate 323, the upper end of the guide post 322 is connected to the top plate 321, the lower end of the guide post 322 is connected to the bottom plate 323, and the connection mode includes a welding or bolt connection mode. Both ends of the guide post 322 extend in the up-down direction. The lower mold 340 is provided with a guide hole adapted to the guide post 322, where the adapted connection means that the outer circumferential surface of the guide post 322 is attached to the inner circumferential surface of the guide hole. Due to the design, the lower die 340 can only move in the up-and-down direction, and the movement is more stable. In addition, the upper mold 330 is also provided with guide holes adapted to the guide posts 322.

In addition, the roller 500 may be fixed to the connecting portion, so that the roller 500 is fixed to the lower mold 340 and cannot rotate.

The axial direction of the roller 500 is perpendicular to the extending and retracting direction of the first driving cylinder 310, the extending and retracting direction of the first driving cylinder 310 is the up-down direction, and the axial direction of the roller 500 is in the horizontal plane, that is, the XY plane, and in this embodiment, the axial direction of the roller 500 is the same as the Y direction.

The driving block 352 is located below the roller 500, the driving block 352 is provided with a slope 355 connected with the roller 500, and the angle between the slope 355 and the horizontal plane may be 30 °, 45 ° or other angles.

In other embodiments, as shown in fig. 4, the positioning mechanism 300 further includes a stop block 353.

The limiting block 353 is arranged above the driving block 352 and connected with the driving block 352, for example, the limiting block 353 and the driving block 352 are fixed by an integral forming mode, a bolt connecting mode or a welding mode, so that the limiting block 353 and the driving block 352 can horizontally move together. The limiting block 353 is provided with a limiting inclined plane 358 connected with the roller 500. The height distance between the limit ramps 358 and the ramps 355 is equal to or slightly greater than the diameter of the roller 500.

The limiting block 353 is provided to avoid that the lower mold 340 moves upwards due to a large acting force generated between the lower mold and the upper mold 330 during mold splitting, so that mold splitting cannot be completed. When the driving block 352 moves in the opposite direction, the limiting block 353 located above the roller 500 applies an acting force to the roller 500 to drive the roller 500 to move downward, so that the lower mold 340 moves downward, and the mold splitting process is guaranteed to be completed smoothly.

Further, the driving block 352 is provided with a first plane 354 and a second plane 356 which are connected to the roller 500, an upper edge of the inclined surface 355 is connected to the first plane 354, and a lower edge of the inclined surface 355 is connected to the second plane 356, that is, the first plane 354 is higher than the second plane 356.

The limiting block 353 is provided with a first limiting plane 357 and a second limiting plane 359 which are connected with the roller 500, the upper edge of the limiting inclined plane 358 is connected with the first limiting plane 357, and the lower edge of the limiting inclined plane 358 is connected with the second limiting plane 359, that is, the first limiting plane 357 is higher than the second limiting plane 359.

The height distance between the first limit plane 357 and the first plane 354 is equal to or slightly greater than the diameter of the roller 500. The height distance between the second limit plane 359 and the second plane 356 is equal to or slightly greater than the diameter of the roller 500.

During the mold splitting process, the roller 500 is pressed by the first limiting plane 357, the limiting slope 358 and the second limiting plane 359, and moves downwards steadily. The first limiting plane 357 can prevent the lower mold 340 from moving upward due to the force applied to the upper mold 330 during the mold separation. The second stopper plane 359 ensures that the lower mold 340 moves down to the position and contacts the second plane 356.
