Block is connect, the oil cylinder contiguous block is connected by cylinder connector with cylinder piston rod, and chute is formed with the sliding block, and the oil cylinder connects
Connect block sidepiece and be formed with the first projection, first projection is placed in the chute, first projection and the chute inwall it
Between form gap；Cavity is formed with the slider guide I-shaped, lift block is provided with the cavity, spring is formed with the lift block
Groove, the spring groove is interior to be provided with spring, and the lift block top is formed with groove, and the both sides inwall of the groove is formed slopely first
Inclined-plane, the oil cylinder contiguous block bottom are formed with the second projection, and the bottom of second projection is formed with to be coordinated with first inclined-plane
The second inclined-plane, the bottom of the sliding block is formed with locked groove, when second projection is slipped into the groove, on the lift block
In the floating embedded locked groove, when second projection is skidded off in the groove, the lift block is lowered away from the locked groove.
As the further optimization of above-mentioned technical proposal, one end top of the lift block away from sliding block is formed with and described
The 3rd inclined-plane that two inclined-planes coordinate.
As the further optimization of above-mentioned technical proposal, the chute is provided with stopper slot, and gear is provided with the stopper slot
Plate.
Compared with prior art, the utility model utilizes the lift block pair being arranged in mould without additional clamping apparatus
Sliding block is locked, while is not increasing volume using the cooperation between sliding block, lift block and oil cylinder contiguous block after cylinder movement
Sliding block is set to automatically terminate lock-out state in the case of outer process, simple in construction, injection cycle is short, and manufacturing cost is low, and fault rate is low.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is the cross section structure diagram of the utility model mode-lock status.
Fig. 3 is the cross section structure diagram that the utility model completes core pulling action state.
Fig. 4 is the partial enlarged drawing at A in Fig. 2.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.As Figure 1-4, self-locking
Sliding block core-pulling mechanism, including slider guide I-shaped 1 and the sliding block 2 that is horizontally slipped positioned at the interior energy of slider guide I-shaped 1, it is described
The side of sliding block 2 is fixedly connected with fuse 7, and oil cylinder contiguous block 3, the oil cylinder are provided with the sidepiece of the sliding block 2 away from fuse 7
Contiguous block 3 is connected by cylinder connector 31 with the piston rod of oil cylinder, and chute 21, the oil cylinder contiguous block 3 are formed with the sliding block 2
Sidepiece is formed with the first projection 32, and first projection 32 is placed in the chute 21, and the width of first projection 32 is less than
The width of the chute 21 so that gap 6 is formed between the first projection 32 and the inwall of the chute 21；The slider guide I-shaped
Cavity is formed with 1, lift block 4 is provided with the cavity, spring groove is formed with the lift block 4, spring is provided with the spring groove
5, the top of lift block 4 is formed with groove 41, and the both sides inwall of the groove 41 is formed slopely the first inclined-plane 411, the oil cylinder
The bottom of contiguous block 3 is formed with the second projection 33, and the bottom of second projection 33 is formed with coordinate with first inclined-plane 411 second
Inclined-plane 331, the bottom of the sliding block 2 are formed with locked groove 22, when second projection 33 is slipped into the groove 41, the buoyance lift
Block 4 floats in the embedded locked groove 22, when second projection 33 is skidded off in the groove 41, the lift block 4 decline from
Open the locked groove 22.
In above-mentioned technical proposal, one end top of the lift block 4 away from sliding block is formed with to be coordinated with second inclined-plane 331
The 3rd inclined-plane 42, oil cylinder contiguous block 3 reply sliding process in make the 3rd inclined-plane 42 and the contact slide of the second inclined-plane 331 more
It is smooth.
In above-mentioned technical proposal, the chute 21 is provided with stopper slot 211, and baffle plate is provided with the stopper slot 211, to prevent
First projection 32 departs from chute 21 in the course of the work.
The course of work of the present utility model is as follows, as shown in Fig. 2 core-pulling mechanism is in mode-lock status, the piston rod of oil cylinder
Start to shrink at, drive oil cylinder contiguous block 3 to move right, lift block 4 is gradual under the effect of the second inclined-plane 331 of oil cylinder contiguous block 3
Decline, until the first projection 32 touches with the right cell wall of chute 21, now the second projection 33 of oil cylinder contiguous block 3 skids off described recessed
Groove 41, spring 5 is compressed during being somebody's turn to do, and lift block 4 is also lowered away from the locked groove 22, releases the locking to sliding block 2；Oil cylinder
Piston rod continues to shrink, and because first projection 32 touches with the 21 right cell wall of chute on sliding block 2 on oil cylinder contiguous block 3, oil cylinder connects
Connect block 3 also to move right with movable slider 2 and fuse 7, until such as Fig. 3 positions, now complete whole core pulling action.
The utility model is locked using the lift block 4 being arranged in mould to sliding block 2 without additional clamping apparatus,
Do not increasing the feelings of process using the cooperation movement between sliding block 2, lift block 4 and oil cylinder contiguous block 3 under oil cylinder drive simultaneously
