Description
Technical field
The present invention relates to injection mold, particularly relate to injection mold and postpone side core-pulling mechanism.
Background technology
After injection mold is to working of plastics injection mo(u)lding, if the sidewall of working of plastics is shaped with bulge loop, groove and through hole simultaneously, prior art is typically with side action sliders and extracts bulge loop, groove and through hole simultaneously out, and due to working of plastics after moulding, it is big to the package power of side action sliders, it is easily caused working of plastics deformation if extract out simultaneously, is even pulled off.
Summary of the invention
The invention aims to the shortcoming overcoming prior art to exist, it is provided that a kind of bulge loop first extracting working of plastics out and groove, then extract the through hole of working of plastics out, loose core smoothly, it is ensured that finished product rate, the injection mold of simple in construction postpones side core-pulling mechanism.
nullInjection mold of the present invention postpones the technical scheme of side core-pulling mechanism: include compound plate and lower compound plate，Under upper compound plate, die cavity is set，Perforation is had in lower compound plate，On lower compound plate, mould foot is set，On lower compound plate between mould foot, ejector retainner plate is set、Lower ejector retainner plate and thimble，Injector push rod contacts through perforation with lower ejector retainner plate，On mould foot, backing plate is set，Core and side action sliders are set on backing plate，At die cavity、The working of plastics of injection mo(u)lding is had between core and side action sliders，The sidewall of working of plastics is shaped with bulge loop、Groove and through hole，It is characterized in that: under described upper compound plate, block is set，Block inwall is shaped with interior inclined-plane and trough with straight angle，Spring groove is had between core and side action sliders，Spring groove arranges sliding block spring，Side pumping slot is had in side action sliders，Outside the pumping slot of side, fixed plate is set，Fixed plate outer wall is shaped with outer inclined-plane，The outer inclined-plane of fixed plate contacts with the interior inclined-plane of baffle plate，Side core-pulling bar is set in the pumping slot of side，It is shaped with baffle plate on side core-pulling bar，Side core-pulling bar outer wall is positioned on the left of baffle plate and arranges delay spring，One, side core-pulling bar matches through side action sliders with the through hole of working of plastics，Match through fixed plate with the trough with straight angle of block in side core-pulling bar other end.
The invention discloses a kind of injection mold and postpone side core-pulling mechanism, when after working of plastics injection mo(u)lding, lower compound plate band dynamic model foot, upper ejector retainner plate, lower ejector retainner plate, thimble, backing plate, core, side action sliders and working of plastics are moved rearwards by, mould is gradually opened, now sliding block spring pushes out side action sliders under restoring force effect, and owing to side core-pulling bar contacts with the trough with straight angle of block, side action sliders side core-pulling bar when being displaced outwardly still remains stationary as, played a supporting role by side core-pulling pole pair working of plastics, side action sliders is made first to deviate from bulge loop and the groove of working of plastics, realize side core-pulling for the first time；And lower compound plate continues band dynamic model foot, upper ejector retainner plate, lower ejector retainner plate, thimble, backing plate, core, side action sliders and working of plastics and is moved rearwards by, when side core-pulling bar contacts with the interior inclined-plane of block downwards, postpone spring and push out baffle plate under restoring force effect, baffle plate drives side core-pulling bar to be displaced outwardly, the through hole of working of plastics the most outwards extracted out by side core-pulling bar along the interior inclined-plane of block, realize second time side core-pulling, finally driven thimble by working of plastics ejection device by upper and lower ejector retainner plate.This programme injection mold postpones side core-pulling mechanism, trough with straight angle first with block coordinates with side core-pulling bar, the interior inclined-plane of block coordinates with the outer inclined-plane of fixed plate outside side action sliders, during making mould be gradually opened, first side action sliders is extracted out bulge loop and the groove of working of plastics, working of plastics is then played a supporting role by side core-pulling bar, prevent working of plastics from deforming to side, the interior inclined-plane of recycling block coordinates with side core-pulling bar, side core-pulling bar is extracted out the through hole of working of plastics, side core-pulling the most at twice, effectively reduce the working of plastics package power to side action sliders, working of plastics is made to loose core smoothly, ensure finished product rate.
Injection mold of the present invention postpones side core-pulling mechanism, and the side of described backing plate arranges limited block, and limited block is spacing with side action sliders to be contacted.Having had limited block, the distance sliding in and out side action sliders carries out spacing, prevents sliding block spring from side action sliders ejecting hypertelorism, and causes resetting.Described side core-pulling bar is positioned on block side and is shaped with oblique surface.There is oblique surface, contacted with oblique surface by the interior inclined-plane of block when matched moulds, promoted side core-pulling bar to reset.
