Description

The full-automatic injection moulding bottle blowing of three stations device

The utility model belongs to the former technical field of plastics, more particularly relates to utilize the device of injection machine blowing hollow product.

Existing injection moulding bottle blowing equipment is that 93226738.6 plastic cement penetrates bottle blowing machine as the patent No., though can realize automatic bottle blowing, adopts 180 ° of rotary two stations, and inefficiency, goods are deviate from difficult.Though the mould multi-cavity is difficult for making, package unit complex structure, cost are too high, are difficult to make mould bottle more greatly on common small injecting machine.It is obvious that the body of making penetrates the mould parting line, and the body smoothness is relatively poor.

The purpose of this utility model is will provide a kind of to make a bottle high efficiency, mould are easy to manufacture, the full-automatic injection moulding bottle blowing device of stable and reliable product quality.

The technical solution of the utility model is: it comprises solid plate and is installed in moving platen on the pull bar, and its design feature is that the punch fluid motor is installed on the moving platen and is the driven pulley that axle rotates by the driving wheel of its driving with the pull bar.The side of driven pulley is equipped with three identical punch assemblies, and this punch assembly evenly divides on the same circumference that with the pull bar is the center.Injection molding assembly, blowing mould assembly and bottle removing mechanism are installed on solid plate, and it is on the same circumference at center that the three also is that hexagonal angle is evenly distributed on the pull bar, and corresponding with three punch assembly positions, blowing mould assembly top is equipped with the differential cylinder of its folding of control.

The spring that each punch assembly of the present utility model comprises two punch slide blocks and is installed in the interior telescopic punch insert of slide block and is contained in its back has gas passage on the protruding horizontal core, has two pin-and-holes on each punch slide block.The blowing mould assembly also comprises two slide blocks, have on each slide block two with the punch slide block on the corresponding latch in pin-and-hole position.

Bottle removing mechanism of the present utility model constitutes by taking off its flexible bottle cylinder that takes off of bottle manipulator and control.

Compared with prior art, the utlity model has following advantage:

1, adopt 120 ° of rotations of punch three stations, three stations are worked simultaneously, do not have the stand-by period, and injection, bottle blowing, take off bottle and once finish synchronously, high efficiency, energy consumption is low;

2, demoulding station is outside machine, and goods are deviate from easily, need not manual operation, and sanitary condition is good;

3, mould is easy to manufacture, and cost is low, can realize a multi-cavity mold, and the adapted small injecting machine can be made the bottle of moulding of larger capacity;

4, make to mould bottle steady quality reliable, it is smooth evenly not have the mould of ejaculation parting line body, bottleneck precision height, the envelope bottle is effective.

Below in conjunction with drawings and Examples structure of the present utility model and operation principle are described in further detail.

Fig. 1 is a transverse sectional view of the present utility model, shows its overall structure;

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is the B-B cutaway view among Fig. 1.

In the embodiment that accompanying drawing provides, solid plate 10 is fixed on the body, and moving platen 3 is installed in two one ends and is fixed on the pull bar 2 on the solid plate.Moving platen 3 is promoted reciprocating along pull bar 2 by reciprocal locking cylinder 1, finish the die opening and closing action.Punch fluid motor 4 is fixed on the moving platen 3, drives driven pulley 6 by driving wheel 5 and rotates along the axis that with pull bar 2 is the center.Driven pulley 6 is a fluted disc, and the center studs with ball rotary sleeve 16, rotary sleeve 16 lining with the concentric moving platen projection of pull bar 2 on, driven pulley 6 is spacing by swivel nut 15 lockings.Be equipped with three and play the punch assembly 7 of rotation with one on the side of driven pulley 6, being hexagonal angle, to be evenly distributed on pull bar 2 be on the same circumference in axle center.Each punch assembly 7 comprises two punch slide blocks and is installed in telescopic punch insert 14 in the slide block; spring is equipped with in punch insert 14 back; have two pin-and-holes 17 on each punch slide block, having the gas passage that is communicated with air admission hole 18 on the driven pulley 6 on the punch insert 14.Injection moulding assembly 13 is installed on solid plate 10, blowing mould assembly 9 and bottle removing mechanism 25, the three also is hexagonal angle, and to be evenly distributed on pull bar 2 be on the same circumference at center, corresponding with three punch assembly 7 positions.Blowing mould assembly 9 also comprises two slide blocks, have on each slide block two with the punch slide block on the corresponding latch 21 in pin-and-hole 17 positions.Be installed in of the folding of the differential cylinder 8 of blowing mould assembly 9 tops by blowing mould push rod 19,20 control blowing mould assemblies 9.Have on the solid plate 10 one connect with source of the gas and with driven pulley 6 on the corresponding venthole 22 in air admission hole 18 positions.Bottle removing mechanism 25 is made of bottle removing mechanism hand 23 and its flexible bottle cylinder 24 that takes off of control.

During work, at first each mould is adjusted to the right place.For the first time during matched moulds, one in the punch assembly 7 heat is melted material under the rotation of screw rod 12 promotes at injection station and injection molding assembly 13 matched moulds, injects injection molding assemblies 13 by barrel 11 and forms bottle base, all the other two stations waits.After above-mentioned action was finished, whole die sinking put in place, and punch liquid changes 6 rotations of motor 4 driving driven pulleys and puts in place for 120 °, then carries out the matched moulds second time.At this moment repeat to move just now at second punch assembly of injection station 7 and injection molding assembly 13 matched moulds; and at the bottle blowing station; first punch assembly 7 and blowing mould assembly 9 matched moulds; latch 21 on the blowing mould slide block enters in the pin-and-hole 17 in the punch slide block; venthole 22 on the solid plate 10 communicates with a air admission hole 18 on the driven pulley 6; the elastic force that overcomes spring from the gas of source of the gas is gone out bottle blowing moulding and pressurize by the gas passage on the punch insert 14.After above-mentioned action was finished, blowing mould assembly 9 was opened under the promotion of differential cylinder 8, and this punch assembly 7 is also opened under the stirring of latch 21, moulded bottle and still was retained in the punch of opening, and took off bottle station and still was in wait state.After whole die sinking puts in place, fluid motor 4 drives driven pulley 6 again and rotates 120 ° again and put in place, carry out matched moulds for the third time then, injection, bottle blowing two stations repeat above-mentioned action, and taking off a bottle station this moment, when taking off bottle manipulator 23 and being inserted into the bottleneck recess treating die sinking under taking off bottle cylinder 24 control, punch assembly 7 leaves, and manipulator 23 is motionless, and shaped bottle is deviate from because of deadweight falls, and takes off bottle cylinder 24 and drives manipulator 23 returns.Like this injection, bottle blowing, take off bottle and finished one-period in turn, go round and begin again then, three stations synchronous workings realizes the full-automatic process of injection moulding bottle blowing.
