Accompanying drawing explanation
Fig. 1 is a kind of three auxiliary ejection mechanisms of the present invention and mould structure composition schematic diagram thereof.
Detailed description of the invention
Figure 1 shows that related description figure of the present invention;
A kind of three auxiliary ejection mechanisms and mould thereof, comprise upper clamping plate 1, guide pillar 2, cavity plate 3, secondary auxiliary ejection spring 4, auxiliary ejection spring 5, the push pedal 6 of de-material, core fixing plate 7, dynamic model backing plate 8, release link 9, thimble panel 10, thimble push plate 11, counterdie seat board 12, support column 13, release link 14, three auxiliary ejection cores 15, auxiliary ejection core 16, secondary auxiliary ejection core 17.
Described mould die carrier structure is made up of upper clamping plate 1, guide pillar 2, cavity plate 3, core fixing plate 7, dynamic model backing plate 8, counterdie seat board 12, support column 13;
Described ejecting mechanism is made up of secondary auxiliary ejection spring 4, auxiliary ejection spring 5, the push pedal 6 of de-material, release link 9, thimble panel 10, thimble push plate 11, release link 14, three auxiliary ejection cores 15, auxiliary ejection core 16, secondary auxiliary ejection core 17;
Described de-material push pedal 6, thimble panel 10, thimble push plate 11, release link 14 form edge ejecting mechanism, and release link 14 is installed on thimble panel 10, thimble push plate 11, and its upper end and thimble push plate 11 are connect by screw fastening;
A described auxiliary ejection spring 5 and an auxiliary ejection core 16 form an auxiliary ejection mechanism; Secondary auxiliary ejection spring 4 and secondary auxiliary ejection core 17 form secondary auxiliary ejection mechanism; Three times auxiliary ejection core 15 forms three auxiliary ejection mechanisms, and its lower end is connected with injection machine push rod and thimble push plate 11 by screw;
Described three auxiliary ejection cores 15, auxiliary ejection core 16, secondary auxiliary ejection core 17 float and install with in mold cores, can slide by limited travel in mould die sinking direction, by different ladder stacked assembling between three;
Described secondary auxiliary ejection spring 4 is installed in secondary auxiliary ejection core 17 by the pin that floats, and one time auxiliary ejection spring 5 is installed in an auxiliary ejection core 16 by the pin that floats.
During real work, as shown in Figure 1, its motion running can be divided into several step:
1) after ejection die die cavity is opened, thimble panel 10 will be promoted at injection machine push rod, thimble push plate 11 promotes three auxiliary ejection cores 15, release link 9, product ejects from core by the push pedal 6 of de-material, now, due to an auxiliary ejection core 16, secondary auxiliary ejection core 17 loses the thrust of three auxiliary ejection cores 15, at an auxiliary ejection spring 5, under the elastic force bounce-back jacking of secondary auxiliary ejection spring 4, move upward simultaneously, assist and product is ejected together, until be subject to the restriction of limited step successively, thus complete once, secondary auxiliary ejection, three auxiliary ejection cores 15, by being synchronized with ejecting of de-material push pedal 6 always, complete three auxiliary ejection functions of mechanism, until ejected from mold cores completely by product,
2) when resetting, before mold cavity is closed, thimble panel 10, thimble push plate 11, three auxiliary ejection cores 15, release link 9, the push pedal 6 of de-material synchronously retract by injection machine push rod by mould release link, now, compressing auxiliary ejection core 16, secondary auxiliary ejection core 17 are overcome auxiliary ejection spring 5 by three auxiliary ejection cores 15, the elastic force of secondary auxiliary ejection spring 4 forces the two to reset, mould closes, and waits for that next injection cycle starts.
