The mechanism slips component includes the first slide body 6, the second slide body 7, unlocking insert 13, lock core spring 14, lock Core 15, sliding block cut spring 16, sliding block pull bar 17;First slide body 6, the second slide body 7 are coupled by sliding block pull bar 17, lock core Spring 14 is placed on sliding block pull bar 17 and is installed in the first slide body 6, is to separate the first slide body 6 and second for core pulling action Slide body 7, sliding block pull bar 17 is used to control separating distance between the two;Unlocking insert 13 is installed on the first sliding block by screw On body 6, its head is provided with the convex pressure head of unlocking, and for lock core 15 to be pushed, lock core 15 is installed on take-up housing 3, its lower end peace Equipped with lock core spring 14, lock core spring 14 is used to ensure the lock-bit reliability of lock core 15, and the Main Function of lock core 15 is to ensure to start During core pulling, it is motionless that the second slide body 7 is locked in original position by the first slide body 6, the second slide body 7 when separating;The bottom of second slide body 7 Portion is provided with lock-bit groove corresponding with lock core 15;The inner side of take-up housing 3 is provided with square groove, for the first slide body 6, the second slide body 7 Core pulling and the slip that resets on take-up housing 3, as shown in Fig. 3, Fig. 4, Fig. 7.
The mechanism can realize twice core pulling function at three, mold insert 10 and central inner core pulling centered on first time core pulling action Synchronous core pulling at 12 liang of spill mold insert;Second core pulling is that the first slider head mold insert 8, the synchronization of the second slider head mold insert 9 are taken out Core.
Mechanism's core pulling power and support component include core pulling oil cylinder 1, oil cylinder installing plate 2, take-up housing 3, oil cylinder pull bar 4;Take-up housing 3 is the support member of whole mechanism, and core pulling oil cylinder 1 is installed on take-up housing 3 by oil cylinder installing plate 2, core pulling oil cylinder 1 The first slide body 6, the second slide body 7 is driven to complete core pulling and homing action by oil cylinder pull bar 4.
During real work, as shown in Fig. 4, Fig. 8, Fig. 9, its motion operation principle is as follows:
1)The injection of first time core-pulling die is finished, and after die sinking, die joint is opened, the cavity surface demoulding;Wedging briquetting 5 loses Go the pressuring action to the first slide body 6, core pulling oil cylinder 1 to act, pull the first slide body 6 to press institute in Fig. 8 by oil cylinder pull bar 4 Show the core pulling of K directions, sliding block cut spring 16 is flicked this moment, the second slide body 7 is propped up and do not allow it and move, to ensure the first sliding block Body 6 is first slided, and the first slide body 6 will skid off the K1 of the S1 distances as shown in Fig. 8, Fig. 9 to core pulling with center mold insert 10, synchronous Ground, the pin 11 of stirring of center mold insert 10 will force central inner core pulling spill by the sliding guide groove of central inner core pulling spill mold insert 12 The direction movement as shown in K2 in Fig. 9 of mold insert 12 completes inner core pullings of the S2 apart from length;S2 is treated after the completion of inner core pulling, first slides The second slide body of ability stretchy 7 of block 6 is extracted out along K directions, and control is then completed by unlocking insert 13;Thus, take out for the first time Core completes the core pulling of product central circular hole position and edge circular hole madial wall square hole position, i.e. center mold insert 10, central inner core pulling spill The action core pulling of moulding section at the two of mold insert 12, as shown in Fig. 4, Fig. 8, Fig. 9, direction shown in K, K1 is same direction;
2)At the end of the core pulling of second core pulling first, unlocking insert 13 follow the first slide body 6 along K directions move S1 away from From rear, its head concave part lock core 15 overcomes the bullet top resistance of lock core spring 14 to be depressed along M directions, so that lock core 15 loses To the pinning inhibition of the second slide body 7, can be held by sliding block pull bar 17, follow the first slide body 6 along K to doing core pulling Motion, thus, second core pulling completes the core pulling of product edge circular hole, that is, drive the first slider head mold insert 8, the second slider head to inlay Part 9 completes the core pulling of edge circular hole position;, during second core pulling, lock core 15 is depressed always, as shown in Figure 8;
3)When resetting, core pulling oil cylinder 1 is acted, and promotes the first slide body 6 to press K shown in Fig. 8 by oil cylinder pull bar 4 Direction is reversely pushed back, and the second slide body 7 will be propped up and moved together by the first slide body 6 by sliding block cut spring 16, treat second After slide body 7 resets, lock core 15 is upspring, and is pinned, and the first slide body 6 will continue to oppress sliding block cut spring 16 until first Slide body 6 is resetted completely, and last mould is closed completely, and the first slide body 6 is compressed pinning by wedging briquetting 5 completely, is waited next The beginning of individual injection cycle.
Specific embodiment described herein is only the technology neck belonging to the present invention to the present invention spiritual explanation for example The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode Generation, but without departing from spirit of the invention or surmount scope defined in appended claims.
