Abstract
The utility model discloses a secondary internal core-drawing mechanism for an injection mold of a reducing pipe joint. The secondary internal core-drawing mechanism is characterized by comprising a main mold core, wherein the front end of the main mold core is connected with an internal core-drawing small sliding block; an internal inclined sliding surface is arranged on the inner side of the internal core-drawing small sliding block; a sliding rod is arranged in the main mold core; an external inclined sliding surface is arranged on the sliding rod and is matched with the internal inclined sliding surface; a connecting seat is arranged at the rear end of the main mold core; installing grooves are formed in the rear ends of the connecting seat and are internally provided with fixed plates; the fixed plates are fixed with the connecting seat by screws; sliding seats are arranged at the rear end of the connecting seat and are fixed with the sliding rod by bolts. The secondary internal core-drawing mechanism disclosed by the utility model has the advantages that due to adoption of the scheme, the demolding difficulty of internal back-off is solved, the structure is simple, the demolding is convenient, the internal core-drawing small sliding block is small in size, the type of an injection molding machine is also reduced, an energy-saving effect is achieved, and since the inclination is added at the matching position with the main mold core, the pulling damage of a product caused by the phenomena of friction and locking generated with the main mold core when in core drawing is prevented.
Description
Technical field
The utility model relates to the pipe reducer injection mold, particularly relates to pipe reducer injection mold secondary internal core-pulling mechanism.
Background technology
The reducing fittings joint has played the effect of transition connection drainpipe in water-drainage tube part, conventional reducing joint inside does not have buckle, in assembling, easily come off, therefore people develop the reducing joint of a kind of inside with buckle, and this is a larger difficult problem for mold releasability all to be shaped with buckle inside and outside it.
Summary of the invention
The purpose of this utility model is the shortcoming existed in order to overcome prior art, and a kind of inner core pulling at twice is provided, simple in structure, is convenient in demoulding the pipe reducer injection mold secondary internal core-pulling mechanism that the inner core pulling structure volume is little.
The technical scheme of the utility model pipe reducer injection mold secondary internal core-pulling mechanism is: it is characterized in that: comprise main core, the main core front end connects the inner core pulling small slide block, inner core pulling small slide block inboard is shaped with interior oblique sliding surface, sliding bar is set in main core, be shaped with outer oblique sliding surface on sliding bar, outer tiltedly sliding surface matches with interior oblique sliding surface, Connection Block is installed in the main core rear end, the Connection Block rear end is shaped with mounting groove, mounting plate in mounting groove, fixed head fixes through screw and Connection Block, in the Connection Block rear end, sliding seat is set, sliding seat fixes through bolt and sliding bar.
The utility model discloses a kind of pipe reducer injection mold secondary internal core-pulling mechanism, after the injection mo(u)lding of reducing fittings joint, first by sliding seat, through bolt, driving sliding bar moves backward, and Connection Block and main core maintain static, the outer oblique sliding surface of sliding bar front end coordinates with the interior oblique sliding surface of inner core pulling small slide block, the inner core pulling small slide block is moved to centre, the inner core pulling small slide block is deviate from the interior buckle of reducing fittings joint, realize once loosing core, and sliding seat drive sliding bar continues to move backward, when sliding bar moves to while contacting with fixed head, sliding bar drives fixed head and moves backward, fixed head through screw belt be dynamically connected the seat and main core move backward, deviate from the reducing fittings joint, realize twice core pulling.This programme adopts the mechanism of taking out in secondary, solved the demoulding difficult problem of inner back-off, simple in structure, be convenient in demoulding, inner core pulling small slide block volume is little, model to injection machine also reduces, and plays energy-conservation effect, when with the main core cooperation place, having increased gradient and prevent from loosing core, with main core, produces friction and kills phenomenon and cause product to pull.
The accompanying drawing explanation
Fig. 1 is the schematic perspective view of pipe reducer injection mold secondary internal core-pulling mechanism;
Fig. 2 is the structural representation of pipe reducer injection mold secondary internal core-pulling mechanism;
Fig. 3 is the schematic perspective view of reducing fittings joint.
The specific embodiment
The utility model pipe reducer injection mold secondary internal core-pulling mechanism, as shown in Fig. 1-Fig. 3, it is characterized in that: comprise main core 1, the main core front end connects inner core pulling small slide block 2, inner core pulling small slide block inboard is shaped with interior oblique sliding surface 3, sliding bar 4 is set in main core, be shaped with outer oblique sliding surface 5 on sliding bar, outer tiltedly sliding surface 5 matches with interior oblique sliding surface 3, Connection Block 6 is installed in the main core rear end, the Connection Block rear end is shaped with mounting groove 7, in mounting groove, mounting plate 8, fixed head fixes through screw 9 and Connection Block 6, in the Connection Block rear end, sliding seat 10 is set, sliding seat fixes through bolt 11 and sliding bar 4.After the injection mo(u)lding of reducing fittings joint, first by sliding seat 10, through bolt 11, driving sliding bar 4 moves backward, and Connection Block 6 and main core 1 maintain static, the outer oblique sliding surface 5 of sliding bar 4 front ends coordinates with the interior oblique sliding surface 3 of inner core pulling small slide block 2, the inner core pulling small slide block is moved to centre, the inner core pulling small slide block is deviate from the interior buckle of reducing fittings joint, realize once loosing core, and sliding seat 10 drive sliding bars 4 continue to move backward, when sliding bar moves to while contacting with fixed head 8, sliding bar drives fixed head and moves backward, fixed head moves backward through screw 9 drive Connection Blocks 6 and main core 1, deviate from the reducing fittings joint, realize twice core pulling.This programme adopts the mechanism of taking out in secondary, solved the demoulding difficult problem of inner back-off, simple in structure, be convenient in demoulding, inner core pulling small slide block 2 volumes are little, model to injection machine also reduces, and plays energy-conservation effect, when with main core 1 cooperation place, having increased gradient and prevent from loosing core, with main core, produces friction and kills phenomenon and cause product to pull.
