Described screw mandrel is a multi start thread, and the line number can be the 2-16 line, and pitch is 100mm-300mm, left-handed or dextrorotation, tooth depth 2-10mm.
Described screw length is 50mm-200mm, and screw internal diameter, flute profile and line number are corresponding with the screw mandrel working portion to be cooperated.
Described driving gear both ends of the surface are equipped with pressure bearing respectively.
Beneficial features of the present utility model is coarse pitch multi start thread screw mandrel and screw to be applied to mould unload in the screw device, not only have simple in structure, simplify mould structure, shorten the advantage of molding duration and raising die life, and can be made into the mould standard workpiece, be applicable to the automatic mould unloading of the mould of all threaded working of plastics, be suitable for especially that screw thread is dark, production efficiency and product quality have higher mould manufacturing.
Description of drawings
Accompanying drawing is for being equipped with injection mould structural representation of the present utility model.
Among the figure: 1 solid plate, 2 spline pins, 3 moving platens, 3-1 moves plate A, 3-2 moves plate B, and 3-3 moves plate C, and 3-4 moves plate D, 4 screw mandrels, 5 screws, 6 guide pillars, 7 driving gears, 8 alignment pins, 9,10 pressure bearings, 11 cores, 12 driven gears, 13 push pedal thread bush, 14 die bottom plates, 15 push pedals, 16 plastics, 17 push rods, 18 molding machine top thick sticks, 19 pillow blocks, 20 gear seams.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is specified.
Please refer to accompanying drawing, Plastic Parts with Thread pickoff in a kind of injection mould, mainly contain solid plate 1, core 11, guide pillar 6 reaches by moving plate A3-1, moving plate B3-2, the moving platen 3 that moving plate C3-3 and moving plate D3-4 form, it is characterized in that: between moving platen 3 and solid plate 1, the lead screw transmission pair is housed, be connected with screw mandrel 4 in the centre bore of described solid plate 1, screw mandrel 4 one ends are that the many steps of staight shank are inserted or be threaded into formula, its length dimension is decided on solid plate thickness, screw mandrel 4 one ends are provided with pillow block 19, pillow block 19 is affixed with solid plate, and be connected with spline pin 2, prevent that screw mandrel 4 from rotating, the other end of screw mandrel 4 inserts in the push pedal thread bush 13, described moving platen 3 centers are provided with through hole, moving plate C3-3 lower surface in the moving platen 3 is provided with gear seam 20, at moving plate A3-1, moving plate B3-2, be penetrated with screw 5 between the moving plate C3-3 central through hole, the affixed driving gear 7 in screw 5 rear ends, moving plate D3-4 is pressed on the pressure bearing 10 that is socketed on screw 5 rear ends, driving gear 7 and the driven gear 12 planetary engagements that are connected on the core 11, described push pedal thread bush 13 is connected movingly with die bottom plate 14 and is affixed with push pedal 15.Screw mandrel 4 is multi-thread steep-pitch thread, according to injection moulding plastic screw thread specification, its line number can be the 2-16 line, and pitch is 100mm-300mm, left-handed or dextrorotation, tooth depth 2mm-10mm, screw mandrel 4 active length sizes are provided with plurality of specifications, are 100mm-500mm, and screw 5 length are 50mm-200mm, the chamfering of every screw thread front end is consistent with the chamfering of screw end face, is convenient in the arbitrarily angled vertically insertion screw 5 of screw mandrel 4; Screw 5 flute profiles, pitch and line number and 4 corresponding cooperations of screw mandrel.Driving gear 7 both ends of the surface are equipped with pressure bearing 9,10 respectively, to reduce leading screw 4 axial resistances.The utility model operation principle is: when mould is opened after the injection mo(u)lding, screw mandrel 4 was extracted from screw 5 vertically when solid plate 1 separated with moving platen 3, the rotation that under the effect of screw mandrel 4 and the helix of screw 5, screw 5 is produced around its axle center, then driving the driven gear 12 that is fixed in the driving gear 7 on the screw 5 and is engaged with rotates, core 11 reverse rotations with driven gear 12 keyed jointings, core 11 separates with plastic 16, stops operating when the injection moulding machine mould open stroke stops screw 5.At this moment, by screwing out in the plastic 16, injection machine top thick stick 18 promotes to be fixed in the push pedal thread bush 13 of push pedal 15 with screw thread core 11 fully, makes push rod 17 promote moving plate A, and plastic 16 is come off.Take out the material handle.Screw mandrel 4 inserts the readiness that enters next molding cycle in the screw 5 during matched moulds.Demould time only accounted for 0.2 second in each molding cycle, goods do not have take off split, scuffing and metaboly.Product size reaches optimum state.
