It is connect with mounting groove side, the other end of elastic component is connect with closing piece.
Preferably, the convex block is additionally provided with sliding surface, the cell wall of the sliding surface and connecting hole is slidably connected.
The beneficial effects of the utility model：The utility model is by being arranged closing piece and card slot, and closing piece is convex when reusing
Block is pushed into card slot, is clamped with card slot, is realized the self-locking of sliding block, sliding block is effectively prevent to shrink back, avoid when product is unformed
Just injection mold is opened.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is the decomposition texture schematic diagram of the utility model.
Fig. 3 is the mated condition structural schematic diagram of the utility model link block, closing piece, card slot.
Specific implementation mode
1 the utility model is described further to attached drawing 3 and specific implementation mode below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of sliding block self-locking structure for plug rubber shell injection mold, including sliding block 1 and cunning
The both sides of the shovel base 2 that block 1 is slidably connected and the oil cylinder 3 for driving shovel 2 linear slide of base, the shovel base 2 are both provided with fixation
Block 4, formed between two pieces of fixed blocks 4 with shovel 2 matched sliding slot of base, the left end of the shovel base 2 is provided with connecting hole 21, described
The piston rod of oil cylinder 3 is provided with link block 5, and the link block 5 is connected in the connecting hole 21 of shovel base 2, the both sides of the shovel base 2
Two connectivity slots 22 being connected to connecting hole 21 are also respectively provided with, closing piece 6 is both provided in two connectivity slots 22, it is described
Fixed block 4 is provided with the card slot 41 coordinated with closing piece 6, and the both sides of the link block 5 are provided with for closing piece 6 to be pushed into card slot 41
Interior convex block 51；Or the elastic component for releasing closing piece 6 is equipped in connectivity slot 22.
The present embodiment link block 5 is set in the connecting hole 21 of shovel base 2, and oil cylinder 3 pushes shovel base 2 to be moved with movable slider 1, lock
Block 6 is fixed block 4 and blocks；When be moved to closing piece 6 it is opposite with the card slot 41 of fixed block 4 when, the closing piece 6 in connectivity slot 22 can be pushed away
Enter in card slot 41, be clamped with card slot 41, realizes the self-locking of sliding block 1, effectively prevent sliding block 1 to shrink back, avoid unformed in product
When just injection mold is opened.
In the present embodiment, the right end of the shovel base 2 is provided with lower inclined plane 23, and the sliding block 1 is provided with ramp 11, described
Lower inclined plane 23 is abutted with ramp 11, and oil cylinder 3 pushes shovel base 2 to be slided with movable slider 1.
It drives sliding block 1 to move for convenience of shovel base 2, lower inclined plane 23 is set on shovel base 2 here, ramp is set on sliding block 1
11；Can certainly inclined-plane only be set on shovel base 2 or sliding block 1.
