Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail:
Specific embodiment is as shown in fig. 1 to fig. 4, the utility model be it is a kind of convenient for internal buckle muscle moulding demould at Pattern has, including preceding mould 1 and rear mold 2, and type core 3, die cavity inner face and the rear mold 2 of the preceding mould 1 are provided in the rear mold 2 The forming cavity for forming moulding is fastened outside type core,
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 utility model is that the forming cavity for forming moulding is fastened using preceding mould 1 and rear mold 2, in forming cavity Interior perfusion injected plastics material, when product stripping, due to the presence of internal buckle muscle structure, is worked as to obtain product as shown in Figure 5 When mold is 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 exists It under the guiding of outer draw runner 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 distance Increase, outer oblique bullet block 4 is gradually disengaged and far from product, and the outer translational motion that tiltedly bullet block 4 is only opened outward, preceding during being somebody's turn to do Internal buckle muscle protrusion 6 on mould 1 is detached from from the internal buckle muscle of product, when the maximum for reaching outer oblique bullet block 4 and outer 5 sliding gomphosis of draw runner After stroke, outer oblique bullet block 4 is moved integrally and is opened with preceding mould 1, exposes 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 utility model realizes the reduction to equipment volume by integration demoulding outer pushing plate 10 and interior oblique push block 7, and Can be realized the demoulding to internal buckle muscle structure, product can be taken out using manipulator of injection machine, meet automation injection molding production needs, By substituting thimble system, reaches attenuating die cost, save the purpose of production cost, there is extensive market value.
