Description
Technical field
The present invention relates to a kind of ejecting device, particularly relate to one and be applied in injection mold, for the ejecting device that moulding is released.
Background technology
Developing in mould is injection mold faster.Its product is also applied in daily life more and more widely, as each industrial circle such as building, machinery, electronics, instrument, instrument.After moulding completes injection moulding in injection mold, need moulding to take out.At present, conventional taking-up mode has with under type: one is manual taking-up, and namely after injection mold die sinking, mode is by hand taken out in moulding, and its shortcoming is that labour intensity is large, and production efficiency is low; Two is adopt spring ejector, and namely ejected by moulding by spring force, its production efficiency is high, and its shortcoming is that spring force is difficult to control, and poor stability makes the axial displacement of moulding be difficult to control, and spring needs often to change, and adds production cost.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of machinery and release that replacement is taken out by hand and use the ejecting device stable, result of use is good.
Technical solution of the present invention is achieved in that a kind of ejecting device, comprises die shoe, upper bolster, top board and drive unit; Described upper bolster is arranged on die shoe; Described top board is arranged on upper bolster; Described drive unit drives top board to move upward; Described drive unit comprises motor, worm screw, worm gear, gear, tooth bar, pusher plate and push rod; The output shaft of described motor is provided with worm screw; Described worm and wheel matches; The inner of described worm gear is provided with gear; Described wheel and rack matches; Described tooth bar is connected with pusher plate; Described pusher plate is provided with many push rods; The top of described push rod contacts with top board.
Preferably, described pusher plate comprises pusher plate base plate and pusher plate upper plate; Described pusher plate upper plate is arranged on pusher plate base plate; Described pusher plate base plate is connected by guide pillar with pusher plate upper plate; Described tooth bar is connected with pusher plate upper plate.
Preferably, the output shaft of described motor is provided with two bearing blocks; Described two bearing seats are in the two ends of worm screw.
Preferably, described motor is servomotor.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Ejecting device of the present invention, releases moulding with machinery and replaces original craft to take out moulding, reduce labour intensity, improve production efficiency; Meanwhile, just can control the axial displacement of moulding by controlling motor, the spring force overcoming spring ejector is in the past difficult to control, poor stability, and the axial displacement of moulding is difficult to control, and spring needs the frequent deficiency changed.Ejecting device of the present invention, result of use is good, reduces production cost, and production efficiency have also been obtained raising.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of ejecting device of the present invention;
Accompanying drawing 2 is the using state structural representation of ejecting device of the present invention;
Wherein: 1, die shoe; 2, upper bolster; 3, top board; 4, motor; 5, worm screw; 6, worm gear; 7, gear; 8, tooth bar; 9, push rod; 10, output shaft; 11, pusher plate base plate; 12, pusher plate upper plate; 13, guide pillar; 14, bearing block; 15, moulding.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of ejecting device as shown in Figure 1, comprises die shoe 1, upper bolster 2, top board 3 and drive unit; Described upper bolster 2 is arranged on die shoe 1; Described top board 3 is arranged on upper bolster 2; Described drive unit drives top board 3 to move upward; Described drive unit comprises motor 4, worm screw 5, worm gear 6, gear 7, tooth bar 8, pusher plate and push rod 9; The output shaft 10 of described motor 4 is provided with worm screw 5; Described worm screw 5 is matched with worm gear 6; The inner of described worm gear 6 is provided with gear 7; Described gear 7 matches with tooth bar 8; Described tooth bar 8 is connected with pusher plate; Described pusher plate is provided with many push rods 9; The top of described push rod 9 contacts with top board 3; Described pusher plate comprises pusher plate base plate 11 and pusher plate upper plate 12; Described pusher plate upper plate 12 is arranged on pusher plate base plate 11; Described pusher plate base plate 11 is connected by guide pillar 13 with pusher plate upper plate 12; Described tooth bar 8 is connected with pusher plate upper plate 12; The output shaft 10 of described motor 4 is provided with two bearing blocks 14; Described two bearing blocks 14 are positioned at the two ends of worm screw 5.
Of the present invention a kind of ejecting device as shown in Figure 2, after moulding 15 completes injection moulding in injection mold, moulding 15 is arranged in upper bolster 2 and top board 3, now, motor 4 starts, and the output shaft 10 of motor 4 drives worm screw 5 to move, and worm screw 5 drives turbine 6 to rotate, driven gear 7 rotates, band carry-over bar 8 moves up, and drives pusher plate upper plate 12 to move up, thus drives push rod 9 to move up, cause top board 12 to move up, thus reach the object released by moulding 16.
Ejecting device of the present invention, releases moulding with machinery and replaces original craft to take out moulding, reduce labour intensity, improve production efficiency; Meanwhile, just can control the axial displacement of moulding by controlling motor, the spring force overcoming spring ejector is in the past difficult to control, poor stability, and the axial displacement of moulding is difficult to control, and spring needs the frequent deficiency changed.Ejecting device of the present invention, result of use is good, reduces production cost, and production efficiency have also been obtained raising.
Above-mentioned ejecting device, when described motor is servomotor, the stroke that push rod 9 moves up is more accurate, and ejecting device result of use is best.
