Core.
The mechanism 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, it is as follows that it moves operation principle：
1) first time core-pulling die injection is finished, after die sinking, and die joint is opened, and cavity surface has been stripped；Wedging briquetting 5 is lost to
The pressuring action of one slide body 6, core pulling oil cylinder 1 is acted, and the first slide body 6 is pulled by K side shown in Fig. 8 by oil cylinder pull bar 4
To core pulling, sliding block cut spring 16 is flicked this moment, and the second slide body 7 is propped up and does not allow it to move, to ensure the first slide body 6 first
Slide, 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, synchronously, in
Sliding guide groove by central inner core pulling spill mold insert 12 is forced central inner core pulling spill mold insert by the pin 11 of stirring of heart mold insert 10
The 12 direction movements as shown in K2 in Fig. 9 complete inner core pullings of the S2 apart from length；S2 is treated after the completion of inner core pulling, the first slide body
6 the second slide bodies of ability stretchy 7 are extracted out along K directions, and control then to be completed by unlocking insert 13；Thus, first time core pulling is complete
Into 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 mold insert
The action core pulling of moulding section at the two of 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 of core pulling first, unlocking insert 13 follows the first slide body 6 to be moved along K directions after S1 distances,
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 is lost to the
The pinning inhibition of two slide bodies 7, can be held by sliding block pull bar 17, follow the first slide body 6 along K to doing core pulling fortune
It is dynamic, thus, second of core pulling completes the core pulling of product edge circular hole, that is, drives the first slider head mold insert 8, the second slider head mold insert
9 complete the core pulling of edge circular hole position；, during second of 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 anti-by K directions shown in Fig. 8 by oil cylinder pull bar 4
To pushing back, 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 the second slide body 7
After reset, lock core 15 is upspring, and is pinned, and the first slide body 6 will continue to oppress sliding block cut spring 16 until the first slide body 6
Reset completely, last mould is closed completely, the first slide body 6 is compressed and pinned by wedging briquetting 5 completely, waits next injection to follow
The beginning of ring.
