With reference to shown in Fig. 1 and Fig. 2, mould core pulling interlock, including die 10, runner plate 20, oblique top 30, the first core pulling
The core-pulling mechanism 50 of mechanism 40 and second.
With reference to shown in Fig. 3 and Fig. 4, runner plate 20 and die 10 are setting up and down, and oblique top 30 is arranged in die 10, oblique top 30
Moved up and down with respect to the tiltable of die 10, oblique top 30 has a positioning block and the support bar 32 being supported in below locating piece, fixed
The both sides of position block 31 locating piece 31 are recessed formed with the first positioning hole and the second positioning hole respectively, the first core-pulling mechanism 40 and the
Two core-pulling mechanisms 50 are symmetricly set in the both sides of die 10, and the first core-pulling mechanism 40 includes the first core pulling cylinder 41 and the first core pulling
Entering son 42, the first core pulling cylinder 41 acts on the first core pulling and enters son 42 and can drive it close to or away from the first positioning hole, and second
Core-pulling mechanism 50 includes the second core pulling cylinder 51 and the second core pulling enters son 52, and the second core pulling cylinder 51 acts on the second core pulling and enters son
52 and it can be driven close to or away from the second positioning hole, the first core pulling, which enters the core pulling of son 42 and second and enters son 52, to be coaxially disposed.
In the technical scheme, the first core pulling is entered into son, the second core pulling enters son and the three of oblique top 30 forms mutual interlocking gear.Allow whole
Individual core-pulling mechanism has the first core pulling to enter sub- base, the second core pulling enters sub- three fulcrums of base and mutual interlocking gear.So that core pulling enters son
When being molded injection under huge injection pressure, do not deform, off normal, core pulling is entered son and smoothly depart from product depth
Hole.
Due to being obliquely installed the shaping of (non-perpendicular, at an acute angle between support bar and locating piece) injection between support bar and die
Afterwards, oblique top 30 ramps up, and then removes locating piece from the side of product.
Further, the first core pulling, which enters between the core pulling of son 42 and second enters son 52, forms one and locating piece cooperation opening 43,
First core pulling enters the core pulling of son 42 and second and enters son 52 has protruded out the first locating dowel 421 and the second locating dowel into opening 43 respectively
521, the first locating dowel 421 and the second locating dowel 521 coordinate with the first positioning hole and the second positioning hole respectively.
Further, the outer surface of the first locating dowel 421 and the second locating dowel 521 is respectively formed with taper guiding face.
Further, the first core-pulling mechanism 40 includes the first core pulling base 44, and the first core pulling base 44 is connected to first
Between the core pulling of core pulling cylinder 41 and first enters son 42, formed with 0 first blocking surface 441 on the first core pulling base 44；Second core pulling
Mechanism 50 includes the second core pulling base 54, and the second core pulling base 54 is connected to the second core pulling cylinder 51 and the second core pulling enters son 52
Between, formed with the second blocking surface 541 on the second core pulling base 54；The lower section of runner plate 20 is fixed with the He of the first core pulling jacking block 21
Second core pulling jacking block 22, the first core pulling jacking block 21 and the second core pulling jacking block 22 coordinate respectively with the first blocking surface 441 and the second resistance
Block face 541 coordinates to limit its axial movement.

The guiding face that core jacking block slips into.
In this case, the first blocking surface and the second blocking surface are obliquely installed, and its stage portion formed, which has, is more than 90 ° of angles.
The operation principle of this case mould core pulling interlock is as follows：
During shaping, the first core pulling cylinder 41 first and the second core pulling cylinder 51 are worked, and the first core pulling is entered into son 42 and second
Core pulling enter son 52 insert die 10 in, make the first core pulling enter son 42 and second core pulling enter son 52 on locating dowel 421,521, insertion
In positioning hole in oblique top 30, form the first core pulling and enter the form that sub 42, second core pulling enters son 52 and the three of oblique top 30 interlocking.
Then mould matched moulds, sliding block 11 are pushed into die 10, with die 10 by dead.The first core pulling jacking block 21 and second is taken out simultaneously
It is huge when preventing forming machine injection respectively with the first core pulling base 44 and the dieback of the second core pulling base 54 on the top of core jacking block 22
Injection pressure, beats back core-pulling mechanism.Then shaping injection starts.After shaping injection, pressurize, cooling terminate.First mold, sliding block
Retract, while the first core pulling jacking block 21 and the second core pulling jacking block 22 follow runner plate 20 to move, with the first core pulling base 44 and
Two core pulling bases 54 separate.Then the first core pulling cylinder 41 and the second core pulling cylinder 51 are acted, and the first core pulling is entered into son 42 and the
Two core pullings enter son 52 and detach die 10, open the mutual interlocking gear with oblique top 30.Subsequent ejecting product 60, takes out product 60, enters
Next actuation cycle.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
