The specific embodiment
For the technical scheme of the more detailed above-mentioned utility model of statement, below list specific embodiment and carry out Proof Technology effect; It is emphasized that these embodiment are not limited to limit scope of the present utility model for the utility model is described.
The automatic material stripping mechanism that the utility model provides, as depicted in figs. 1 and 2, comprise that male model 100, master mold 200, first enter a little 110, binary point 120, guide pillar 130, enter son 140, take-up housing 150, draw material pin 160, limited screw 170, stripper plate 210, shutter 220, pull bar 230 and position-limitting pin 240, wherein, described male model 100 is oppositely arranged with master mold 200, and between male model 100 and master mold 200, be formed for the cavity of formed product, described first enters a little 110 to be arranged in described master mold 200, and is communicated with described cavity; Described in described binary point 120 is arranged at, enter in son 140, and be communicated with described cavity, in injection moulding process, from first enter a little 110 and binary point 120 to injected plastic in cavity; Described guide pillar 130 is obliquely installed, and the upper end of described guide pillar 130 is fixed on described master mold 200, and described guide pillar 130 passes described take-up housing 150 and stretches in described male model 100, like this, when master mold 200 rises, guide pillar 130 rises thereupon, under the drive of guide pillar 130, take-up housing 150 outwards moves; Described limited screw 170 is fixed in described take-up housing 150, and enters in son 140 described in stretching into through described guide pillar 130, and in the process of outwards moving at take-up housing 150, limited screw 170 departs from gradually into son 140; The described material pin 160 that draws is fixed in described master mold 200, and stretches in described cavity, for pulling stub bar to depart from from entering son 140; Described stripper plate 210 is connected with described master mold 200 by described position-limitting pin 240, and the position of described stripper plate 210 and the position of described cavity corresponding; Described stripper plate 210 is fixedly connected with one end of described pull bar 230 by shutter 220, preferably, described shutter 220 comprises taper bolt and sleeve, the bottom (one end that diameter is less) of described taper bolt is fixed on described stripper plate 210, and described jacket casing is located on described taper bolt and with described pull bar 230 and is fixedly connected with; The other end of described pull bar 230 is connected with described male model 100, particularly, described pull bar 230 is connected with described male model 100 by a spring 250, described spring 250 is always in compressive state, like this, when master mold 200 rises, the sleeve in shutter 220 slides along described taper bolt, and stripper plate 210 and male model 100 are departed from; When sleeve cannot, again to head (one end that diameter the is larger) motion of taper bolt, that is to say, shutter 220 opens to extreme position, and stripper plate 210 utilizes the effect of position-limitting pin 240 and master mold 200 to depart from, and realizes coming off of stub bar.
It should be noted that, please continue to refer to Fig. 1 and Fig. 2, the movable distance of described sleeve on described taper bolt is greater than the vertical distance that described binary point 120 enters son 140 described in the being arranged in distance of Fig. 1 Z direction (along), that is to say, before stripper plate 210 is realized material stripping action, be the extreme position that moves of sleeve on taper bolt before, stub bar has departed from into son 140, thereby reduces die sinking risk; Please emphasis with reference to figure 1, at stub bar, do not depart from completely into sub 140 o'clock, entering son 140 can not follow guide rod 130 and move, therefore the movable distance of described sleeve on described taper bolt is that guide pillar 130 drives the move distance of take-up housing 150 on directions X, like this, the length that enters son 140 described in described limited screw 170 stretches into need to be greater than the now move distance of take-up housing 150 on directions X, to guarantee keeping motionless into son 140.
In addition, automatic material stripping of the present utility model mechanism can be applied to two template dies or three template dies, cold runner or hot flow path.
Please continue to refer to Fig. 1 and Fig. 2, the motion process of automatic material stripping of the present utility model mechanism is as follows:
1. board injection moulding, first enters a little 110 and binary point 120 injected plastic simultaneously, completes formed product, cooling;
2. mould die sinking, under the effect of limited screw 170, guide pillar 130 drives take-up housing 150 to retreat, enter son 140 and keep motionless, until shutter 220 moves to extreme position, now stub bar has departed from into son 140 under the effect of drawing material pin 160, is bonded on stripper plate 210;
3. mould continues die sinking, and stripper plate 210 departs from master mold 200, realizes automatic material stripping, and the move distance of stripper plate 210 is the spacing distance of position-limitting pin 240;
4. mould continues motion, and guide pillar 130 drives take-up housing 150 motion together with entering son 140, completes die sinking.
In sum, the automatic material stripping mechanism that the utility model provides, comprise that male model 100, master mold 200, first enter a little 110, binary point 120, guide pillar 130, enter son 140, take-up housing 150, draw material pin 160, limited screw 170, stripper plate 210, shutter 220, pull bar 230 and position-limitting pin 240, wherein, described male model 100 is oppositely arranged with master mold 200, and between male model 100 and master mold 200, is formed for the cavity of formed product; Described guide pillar 130 is obliquely installed, and one end of described guide pillar 130 is fixed on described master mold 200, and the other end passes described take-up housing 150 and stretches in described male model 100; Described first enters a little 110 to be arranged in described master mold 200, and is communicated with described cavity; Described in described binary point 120 is arranged at, enter in son 140, and be communicated with described cavity; Described limited screw 170 is fixed in described take-up housing 150, and enters in son 140 described in stretching into through described guide pillar 130; The described material pin 160 that draws is fixed in described master mold 200, and stretches in described cavity; Described stripper plate 210 is connected with described master mold 200 by described position-limitting pin 240, and the position of described stripper plate 210 and the position of described cavity corresponding; Described stripper plate 210 is fixedly connected with one end of described pull bar 230 by shutter 220; The other end of described pull bar 230 is connected with described male model 100.In the utility model, when master mold 200 rises, guide pillar 130 drives take-up housing 150 outwards to move, because inserting in son 140, limited screw 170 plays position-limiting action, enter son 140 and keep motionless, and the stub bar entering in cavity from binary point 120 departs from into son 140 under the effect of drawing material pin 160, stripper plate 210 departs from male model 100 under the effect of shutter 220 simultaneously, then under the effect of position-limitting pin 240, depart from master mold 200, realize automatic material stripping; When stub bar with enter son 140 and depart from completely after, limited screw 170 departs from from enter son 140, guide pillar 130 drives take-up housing 150 and enters son 140 and moves upward simultaneously, completes die sinking.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to including these changes and modification.
