Interior slidable sliding block, the side of the sliding block is fixedly connected fuse, and the sliding block connects away from oil cylinder is provided with the sidepiece of fuse
Block is connect, the oil cylinder contiguous block is connected by cylinder connector with cylinder piston rod, chute is formed with the sliding block, 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, is provided with spring in the spring groove, 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 is formed with the second projection, and the bottom of second projection is formed with and coordinates 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 insertion locked groove, when second projection is skidded off in the groove, the lift block is lowered away from the locked groove.
Used as the further optimization of above-mentioned technical proposal, the lift block is formed with and described away from one end top of sliding block
The 3rd inclined-plane that two inclined-planes coordinate.
Used 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, it is of the invention without additional clamping apparatus, using the lift block being arranged in mould to sliding block
Locked, while not increasing extra work 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 sequence, simple structure, injection cycle is short, and low cost of manufacture, fault rate is low.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the invention.
Fig. 2 is the cross section structure diagram of mode-lock status of the present invention.
Fig. 3 is the cross section structure diagram that the present invention completes core pulling operating state.
Fig. 4 is the partial enlarged drawing at A in Fig. 2.
Specific embodiment
The invention will be further described 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, the sliding block
2 side is fixedly connected with fuse 7, and the sliding block 2 is connected away from oil cylinder contiguous block 3, the oil cylinder is provided with the sidepiece of fuse 7
Block 3 is connected by cylinder connector 31 with the piston rod of oil cylinder, and chute 21, the sidepiece of oil cylinder contiguous block 3 are formed with the sliding block 2
Be formed with the first projection 32, first projection 32 is placed in the chute 21, and first projection 32 width less than described
The width of chute 21 so that gap 6 is formed between the first projection 32 and the inwall of the chute 21；On the slider guide I-shaped 1
Cavity is formed with, lift block 4 is provided with the cavity, spring groove is formed with the lift block 4, spring 5, institute are provided with the spring groove
State the top of lift block 4 and be formed with groove 41, the both sides inwall of the groove 41 is formed slopely the first inclined-plane 411, the oil cylinder connection
The bottom of block 3 is formed with the second projection 33, and the bottom of second projection 33 is formed with the second inclined-plane coordinated with first inclined-plane 411
331, the bottom of the sliding block 2 is formed with locked groove 22, when second projection 33 is slipped into the groove 41, the lift block 4
Float in the insertion locked groove 22, when second projection 33 is skidded off in the groove 41, the lift block 4 is lowered away from institute
State locked groove 22.
In above-mentioned technical proposal, the lift block 4 is formed with away from one end top of sliding block and coordinates 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, the stopper slot 211 and is provided with baffle plate, in case
First projection 32 departs from chute 21 in the course of the work.
The course of work of the invention is as follows, as shown in Fig. 2 core-pulling mechanism is in mode-lock status, the piston rod of oil cylinder starts
Shrink, drive oil cylinder contiguous block 3 to move right, lift block 4 is gradually reduced in the case where second inclined-plane 331 of oil cylinder contiguous block 3 is acted on,
Until the first projection 32 is touched with the right cell wall of chute 21, now the second projection 33 of oil cylinder contiguous block 3 skids off the 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；The piston of oil cylinder
Bar continues to shrink, because first projection 32 is touched with the right cell wall of chute 21 on sliding block 2 on oil cylinder contiguous block 3, oil cylinder contiguous block 3
Band movable slider 2 and fuse 7 also move right, until such as Fig. 3 positions, now complete whole core pulling action.
The present invention is locked using the lift block 4 being arranged in mould without additional clamping apparatus to sliding block 2, while
Using the cooperation movement between sliding block 2, lift block 4 and oil cylinder contiguous block 3 under oil cylinder drive, in the case where operation is not increased
