Specific embodiment
With reference to the accompanying drawing and specific embodiment the invention will be further described:
Specific embodiment is as shown in fig. 1 to fig. 4, and the present invention is a kind of shaping mould convenient for demoulding with internal buckle muscle moulding
Have, including preceding mould 1 and rear mold 2, type core 3, the die cavity inner face of the preceding mould 1 and the type core of rear mold 2 are provided in the rear mold 2
Outside fastens the forming cavity to form moulding,
Preceding demoulding mechanism is had additional on the preceding mould 1, the preceding demoulding mechanism includes tiltedly bullet block 4 and setting outside multiple groups
Outer draw runner 5 on preceding mould 1, the outer oblique bullet block 4 form sliding gomphosis with outer draw runner 5, and the outer draw runner 5 is from top to bottom
It is obliquely installed towards the direction away from preceding 1 center line of mould, the outer oblique bullet block 4 surrounds the mould of preceding mould 1 around the center line of preceding mould 1
The medial surface in intracavitary face, the outer oblique bullet block 4 is provided with internal buckle muscle protrusion 6；
Rear demoulding mechanism is had additional in the rear mold 2, the rear demoulding mechanism includes identical as outer oblique 4 quantity of bullet block
Interior oblique push block 7 and the internal chute 8 that is arranged on type core 3, the interior oblique push block 7 and internal chute 8 form sliding gomphosis, described
Internal chute 8 be obliquely installed from bottom to top towards the direction of 3 center line of point to the core, the type core 3 and interior oblique push block 7 surround type
3 outside of core, the lateral surface of the interior oblique push block 7 are provided with internal buckle muscle recess portion 9；
The rear demoulding mechanism further include demoulding outer pushing plate 10, the demoulding outer pushing plate 10 by demoulding oil jar 16 with
Rear mold 2 forms folding cooperation, 7 lower end of interior oblique push block and demoulding 10 sliding gomphosis of outer pushing plate.
The working principle of the invention is that the forming cavity for forming moulding is fastened using preceding mould 1 and rear mold 2, is filled in forming cavity
It infuses injected plastics material and, when product stripping, due to the presence of internal buckle muscle structure, works as mold to obtain product as shown in Figure 5
When being opened from state as shown in Figure 4, by preceding demoulding mechanism, with being gradually opened for preceding mould 1, outer oblique bullet block 4 is slided outside
It under the guiding of item 5, relies on power for support and moves down, preceding mould 1 has separation trend with outer oblique bullet block 4 at this time, as preceding mould 1 opens the increasing of distance
Add, outer oblique bullet block 4 is gradually disengaged and far from product, the outer translational motion that tiltedly bullet block 4 is only opened outward, preceding mould during being somebody's turn to do
Internal buckle muscle protrusion 6 on 1 is detached from from the internal buckle muscle of product, when the maximum row for reaching outer oblique bullet block 4 and outer 5 sliding gomphosis of draw runner
Cheng Hou, outer oblique bullet block 4 are moved integrally and are opened with preceding mould 1, expose product；
At this time as shown in figure 3, product is sleeved on type core 3 under this state, ejected by the demoulding oil jar 16 of setting, demoulding
Outer pushing plate 10, interior oblique push block 7 are opened under the drive of demoulding oil jar 16, and interior oblique push block 7 is gradually pushed away from the internal chute 8 on type core 3
Out, and product is pushed out also with interior oblique push block 7, and with the inclination of internal chute 8, interior oblique push block 7 is gradually gathered, opposing product and
Speech, interior oblique push block 7 move inward, and the internal buckle muscle portion point of product is deviate from from the internal buckle muscle recess portion 9 of interior oblique push block 7, realize product
With the separation of interior oblique push block 7, at this point, product takes out with mold separation, robotic arm completely, demoulding oil jar is retracted, is closed
Mould, then this carries out injection molding production.
Further, it shown in as shown in Figure 2, Figure 3 and Figure 4, is additionally provided in the rear mold 2 and hales hook 11, described hales
Hook 11 is in " 7 " character form structure, is provided on the demoulding outer pushing plate 10 for haling the through-hole that hook 11 passes through, the outer oblique bullet
4 bottom of block is provided with and hales the locating slot 12 of the cooperation of hook 11, and the slot edge of the locating slot 12 is above provided with hook pulling block 13, institute
The locating slot 12 stated surrounds the groove body inner cavity of " 7 " font by hook pulling block 13.Hook 11 and locating slot 12 are haled to cooperation, works as mold
Clamping process in, bullet block 4 is in the state sliped off due to outer at this time tiltedly, such as mould part preceding in Fig. 2 and Fig. 3, outer oblique 4 bottom of bullet block
After portion is contacted with demoulding outer pushing plate 10, gradually slid inward is shunk outer oblique bullet block 4, is haled hook 11 at this time and is caught on the upper of hook pulling block 13
End forms good fixed limit connection, when outer oblique bullet block 4 needs to open, at this time before mould 1 is whole moves up, outer oblique bullet block 4 by
It does not separate with preceding mould 1 temporarily in the extruding of product, is hooked on hook pulling block 13 due to haling hook 11 at this time, thus the preceding mould of strict guarantee
1 to move up be that outer oblique bullet block 4 can be haled hook 11 and pull open, and goes on smoothly die sinking process, when outside outer oblique bullet block 4 tiltedly to haling hook 11
After separating with hook pulling block 13, product has also been separated with outer oblique bullet block 4 at this time, after outer oblique bullet block 4 reaches the stroke end, is haled
Hook 11 nor affects on outer oblique bullet block 4 and moves up with preceding mould 1.
Further, positioning guide column 14, the positioning guide column 14 and demoulding outer pushing plate 10 are provided in the rear mold 2
It vertically and is interspersed on demoulding outer pushing plate 10, positioning guide column 14 plays the positioning action to demoulding outer pushing plate 10, guarantees outside demoulding
The movement of exactly is capable of in push plate 10.
Further, the T-shaped groove-like structure of internal chute 8 guarantees that interior oblique push block 7 smoothly slides in internal chute 8
Without deviating from.
Further, it is provided with heating device 15 on the outer oblique bullet block 4, realizes the whole heating of this mold, reaches
The effect of plastics smooth flow in injection moulding process.
The present invention realizes the reduction to equipment volume by integration demoulding outer pushing plate 10 and interior oblique push block 7, and can
Realize the demoulding to internal buckle muscle structure, product can be taken out using manipulator of injection machine, met automation injection molding production needs, passed through
Thimble system is substituted, reaches attenuating die cost, saves the purpose of production cost, there is extensive market value.
