Description
Technical field
The present invention relates to injection molds, more particularly to threading bend pipe vertical rotating mold.
Background technique
Threading bend pipe is in 90 ° of arc-shaped bends since it is internal, and internal caliber is smaller, thus can not directly core pulling, demoulding,
Prior art is all to use horizontal injection molding (to be molded threading bend pipe to be horizontally placed at threading bend pipe by injection mold
In the die cavity of mold), it is horizontally arranged rack and pinion in a mold, rack and pinion is meshed, moves by powered belt carry-over bar
Dynamic, rack drives gear axial-rotation, gear drives the rotation of arcuate rotation plate, and arcuate rotation strip is moved inner core pulling curved bar and axially revolved
Turn extraction threading bend pipe, which has the drawback that:, will since threading bend pipe is in the die cavity for be horizontally placed at injection mold
Inner core pulling curved bar rotation extraction threading bend pipe, and each rotating mechanism cannot interfere with again, therefore can only set rotating core-pulling mechanism
Set the quadrangle outer wall in injection mold, the rotating core-pulling mechanism at each angle can carry out core pulling to a threading bend pipe, and such one
Secondary mold can only at most be molded four threading bend pipes, to reduce production efficiency, and rotary core pulling machine will be arranged in four angles
Structure keeps mould structure complicated, improves the manufacturing cost of mold.
Summary of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, it is simple to provide a kind of structure, reduces mold system
This is caused, the threading bend pipe vertical rotating mold of production efficiency is improved.
The technical solution that the present invention threads bend pipe vertical rotating mold is: including upper compound plate and lower compound plate, upper compound plate is divided into

Guide post matches, and lower insert core is arranged on the inside of side action sliders, has between moving die insert, fixed die insert and side action sliders perpendicular
The threading bend pipe of vertical injection molding, the threading bend pipe upper end of setting are matched with upper insert core, threading bend pipe lower end and lower edge
Block fuse matches, and mounting base is arranged on the moving template, inner core pulling fixed plate, rotor plate and side core-pulling is arranged in mounting base
Sliding block, inner core pulling fixed plate are mutually fixed through fastener with mounting base, and inner core pulling straight-bar is arranged in inner core pulling fixed plate, and inner core pulling is straight
Bar passes through lower insert core, and the head of inner core pulling straight-bar is formed with inner core pulling curved bar, the bending section of inner core pulling curved bar and threading bend pipe
Position inner wall matches, and rotor plate is mutually fixed through fastener with mounting base, and one of rotor plate is formed with gear, and setting turns in gear
Inner shaft board and outer shaft board is arranged in axis on moving template, is respectively set gear-bearing in inside and outside shaft bearing plate, gear-bearing with
Shaft matches, and rack gear mounting hole is provided in moving template, and lifter rack, lifter rack and gear phase are arranged in rack gear mounting hole
Engagement is arranged air cylinder fixed plate in the two sides of moving template, cylinder is arranged in air cylinder fixed plate, and the piston rod of cylinder is solid across cylinder
Fixed board connects lifter plate, and the lower end of lifter rack is mutually fixed with lifter plate.
The invention discloses a kind of threading bend pipe vertical rotating molds, and after threading bend pipe injection molding, lower compound plate is driven
Support block, upper ejector retainner plate, lower ejector retainner plate, thimble, moving template, moving die insert, mounting base, inner core pulling fixed plate, rotor plate, side core-pulling
Sliding block, air cylinder fixed plate, cylinder, lifter plate, lifter rack and threading bend pipe move downwardly together, and upper compound plate, solid plate, fixed
Mould insert, lock module, upper insert core and inclined guide pillar remain stationary, and are opened mold from fixed die insert and moving die insert, this
When on insert core extraction threading bend pipe it is suitable for reading, at the same time, the oblique guide holes of side action sliders and inclined guide pillar cooperate, and take out side
Core sliding block moves outward while moving down, and side action sliders drive lower insert core to move outward, makes lower insert
Fuse extracts the lower mouth of threading bend pipe out outward, and reserves certain overturning gap to inner core pulling straight-bar and inner core pulling curved bar,
Upper and lower insert core completes core pulling, and after mold die sinking in place, drives lifter plate to move down by the piston rod of cylinder, goes up and down
Strip is moved lifter rack and is moved down along rack gear mounting hole, and the two sides of lifter rack are meshed with gear, and band moving gear rotates,
Gear is rotated through gear-bearing of the shaft in inner shaft board and outer shaft board, and gear band turn movable plate is flipped up, and is rotated
Strip is moved mounting base and is flipped up, and mounting base drives inner core pulling fixed plate, side action sliders to be flipped up, and side action sliders drive
Lower insert core, inner core pulling straight-bar and inner core pulling curved bar rotate upwards, and inner core pulling curved bar is made gradually to rotate out threading bend pipe
Crooked position finally drives upper and lower ejector retainner plate and thimble that will complete the upward ejection device of threading bend pipe of core pulling by power.We
Case threads bend pipe vertical rotating mold, mainly will form vertical die cavity between fixed die insert and moving die insert, makes to be molded into
The threading bend pipe of type is in upright state, then by the lifter rack arranged vertically and gear cooperation, drive rotor plate, mounting base,
Inner core pulling fixed plate, side action sliders are flipped up together, drive lower insert core, inner core pulling straight-bar and interior by side action sliders
Core pulling curved bar rotates out the crooked position of threading bend pipe upwards, in a mold can be simultaneously since threading bend pipe uses vertical distribution
Row is distributed multiple threading bend pipes, and the mechanism of one group of rotary core pulling can drive multiple inner core pulling curved bars to synchronize pumping simultaneously in mold
Core, therefore a secondary mold can be molded multiple threading bend pipes, structure is simpler, reduces die manufacturing cost, improves production
Efficiency.
The present invention threads bend pipe vertical rotating mold, is provided with leading for arc in the inner shaft board and/or outer shaft board
Xiang Kong, is arranged guiding axis in gear, and guiding axis is matched with pilot hole.Guiding axis is limited and led by pilot hole
To guiding axis limits gear, keeps gear spinning movement more accurate, and protecting threading bend pipe being capable of smooth core pulling.
