The specific embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection domain.
Please referring to accompanying drawing 1 to accompanying drawing 4; The utility model mainly comprises B plate 1, back die 2, ejector retainner plate, base plate 5, one-level thimble 6 and secondary thimble 7; In the present embodiment, back die 2 is installed together with B plate 1, wherein; B plate 1 top has the groove that matches with back die 2 shapes, and back die 2 is inlaid in the B plate 1.One-level thimble 6 cooperates respectively with secondary thimble 7 tops and is installed in the die 2 of back; And one-level thimble 6 and secondary thimble 7; Can be movable in the die 2 of back, one-level thimble 6 can extend out to die 2 tops, back with secondary thimble 7 tops, and the product in the die of back 12 is realized ejecting.One-level thimble 6 is respectively equipped with more than one with secondary thimble 7 in the utility model, and in the present embodiment, one-level thimble 6 is provided with two, and secondary thimble 7 is provided with one, and during practical implementation, the concrete quantity of one-level thimble 6 and secondary thimble 7 can be set according to actual needs.In the present embodiment, ejector retainner plate comprises face ejector retainner plate 3 and end ejector retainner plate 4, face ejector retainner plate 3 and the 4 range upon range of settings of end ejector retainner plate; Face ejector retainner plate 3 is arranged on end ejector retainner plate 4 tops, and the bottom of one-level thimble 6 is inserted in the face ejector retainner plate 3, and one-level thimble 6 bottoms are against on the end ejector retainner plate 4; Through the ejecting force that makes progress of end ejector retainner plate 4 generation opposite ejector retainner plates 3, one-level thimble 6 is moved upward, secondary thimble 7 passes face ejector retainner plate 3 and end ejector retainner plate 4; In the present embodiment; Secondary thimble 7 bottoms are equipped with nut 10, and the big I of nut 10 is concrete selected according to the size of secondary thimble 7, can play the effect of locating on the Z direction for secondary thimble 7 through nut 10.In the present embodiment, secondary thimble 7 centre positions are fixed with hanging platform 8, are set with spring 9 on the secondary thimble 7, and spring 9 one ends prop up hanging platform 8, and the other end props up face ejector retainner plate 3, can produce thrust upwards through 9 pairs of secondary thimbles of spring 7.In the present embodiment, in order to dwindle the mold integral volume, have the stopper slot 11 that matches with hanging platform 8 cross sections in B plate 1 bottom corresponding to secondary thimble 7 positions, when secondary thimble 7 realized that product ejects, hanging platform 8 can embed in the stopper slot 11.
The utility model in use, the concrete action of mould is:----thimble ejects, and----taken product away in the mould die sinking.Wherein, the utility model is to ejecting two parts of branch (two-part action links up): first, and all thimble (comprising one-level thimble 6 and secondary thimble 7) ejects; Second portion has part thimble (secondary thimble 7) to stop to eject (if the secondary thimble continues to eject the folder product risks), and another part thimble (one-level thimble 6) continues to eject.
In the present embodiment, the concrete action of first is: ejecting mechanism (be ejector retainner plate, comprise end ejector retainner plate 4 and face ejector retainner plate 3) ejects; At this moment, secondary thimble 7 leans on spring 9 that power is provided, and all the other one-level thimbles 6 lean on end ejector retainner plate 4 that power is provided; When the middle hanging platform 8 of secondary thimble 7 by B plate 1 in stopper slot 11 withstand (for ejecting 20mm, during practical implementation, can set according to actual needs in the present embodiment) can not advance the time; It is motionless that secondary thimble 7 begins to keep, and at this moment, product 12 ejects in the die 2 of back; But product 12 is clung/clamps by the part thimble, the difficult demoulding; At this moment, the concrete action of second portion is: one-level thimble 6 systems continue to eject, and eject fully up to product 12; (for ejecting 25mm, during practical implementation, can set according to actual needs in the present embodiment); Eject completion, at this moment, the thimble of clamping product has broken away from product; Product can be easy to the demoulding, and the wait manipulator is taken away.
Adopt the utility model to be used for product when mould ejects, can be not too much because of thimble, thimble clings/clamps product; Can realize product stripping smoothly, make things convenient for manipulator to take out product, and can guarantee the full-automatic safety in production of mould realization; The structure of the utility model takes up room little; Simplify mould structure greatly, reduce manufacturing cost, promote die life.
