Description

Full-automatic injection blow-moulding shaper for hollow plastics

The utility model is that a kind of full-automatic injecting draws and blows the plastic blow moulding machine.

The plastic hollow moulding process of present non-stretching type mainly contains two classes: a class is an extrusion blow plastic blow moulding machine.Another kind of is to annotate to blow the plastic blow moulding machine, the advantage of extrusion blow-molded technology is that die cost is low, and is easy at uniform machinery up conversion product variety, and its shortcoming is that the bottleneck precision is low, sealing is poor, waste material is many end to end, blowing must be carried out secondary operations to bottleneck during wide-mouth bottle, and expense height, quality are low.And the advantage of injection blow moulding technology is a goods precision height, and the bottleneck good seal performance does not have waste material end to end, its shortcoming is a complex process, and die cost is high, and the user almost can not change product variety on uniform machinery, the goods of the production in enormous quantities of suitable single variety only, machine involves great expense.

The purpose of this utility model just provides a kind of advantage that can comprehensively absorb extrusion blow-molded technology and injection blow moulding technology, rejects the shortcoming of these two kinds of moulding process, makes that plastic hollow goods precision height, bottleneck good seal performance, the die cost produced are low, the user is easy to change product variety, production efficiency height, material tail full-automatic injecting few, that energy consumption is low, volume is little and draws and blow the plastic blow moulding machine on uniform machinery.

Solution of the present utility model is such: die head device 1 also can move up and down over against head 3 and draw, when die head device 1 is displaced downwardly to head 3, by head or the injection moulding of thread bottle oral area part of Bottle-mouth die 14, bottleneck core 12 with the plastic hollow goods, make goods head non-trimming waste material, move on the die head device 1 then, molten plastic is pulled out be distracted into the pipe embryo.Blow molding die device 2 is in the both sides of die head device 1, when die head device 1 moves down, blow mold 6 separately, when plastic hollow goods head or the injection moulding of screw thread bottleneck, and after being distracted into the pipe embryo by die head device 1, blow mold 6 matched moulds, blowing cooling forming.After taking above-mentioned measure, its plastic hollow goods head or screw thread bottleneck are injection moulding, and its precision height, whole plastic hollow goods have only the bottom that some waste materials are arranged, and whole technology is once High-Speed Automatic finishes.

The utility model has the advantages that plastic hollow goods precision height, the bottleneck good seal performance of being produced, die cost is low, and the user is easy to change product variety on uniform machinery, the production efficiency height, and the material tail is few, and energy consumption is low, volume is little.

The utility model includes die head device 1, blow molding die device 2, head 3, cut bottle at the bottom of device 4, robot device 5.Die head device 1 drives to move up and down over against head 3 and by the die head oil cylinder and draws, its Bottle-mouth die 14, bottleneck core 12 can be pulled out molten plastic from head 3, when die head device 1 is displaced downwardly to head 3, by head or the injection moulding of thread bottle oral area part of Bottle-mouth die 14, bottleneck core 12 with the plastic hollow goods, make goods head non-trimming waste material, move on the die head device 1 then, molten plastic is pulled out be distracted into the pipe embryo.Blowing device 2 is in the both sides of die head device 1, and when die head device 1 moved down, blow mold 6 separated, when the plastic hollow goods are distracted into the pipe embryo by die head device 1 after, and blow mold 6 matched moulds, the blowing cooling forming is made the plastic hollow goods.

Die head device 1 of the present utility model adopts small oil tank 10 to drive Bottle-mouth die 14 and bottleneck core 12 simultaneously as shown in Figure 6, makes itself and mouthful mould form an accurate bottleneck moulding injection mould, and traction body pipe embryo.Bottle-mouth die 14 is three lobe Bottle-mouth dies, its outer garden is enclosed within the sleeve pipe for the garden frustum, when moving on the small oil tank 10 drive sleeve pipes, Bottle-mouth die 14 opens the demoulding under the elastic force effect of spring 13, when sleeve pipe moved down, sleeve pipe played the crushing block effect, the garden frustum of extruding Bottle-mouth die 14, Bottle-mouth die 14 is closed up, carry out bottleneck moulding injection.Sleeve pipe is to be connected with small oil tank 10 by connecting rod 11.Head 3 has the annular gap between plug 24 and mouthful mould 22 as shown in Figure 8, has helicla flute on the plug 25, is provided with hot flow path heater 26 near the head 1 helicla flute.Molten plastic enters helicla flute from charging aperture, extrudes from the annular gap, and adjustment screw 27 is all arranged on each feeding-passage, to guarantee Products Quality.The extracting of manufactured goods 9 is to be finished by robot device 5, robot device 5 adopts Pneumatic Transmission, constitute by paw 15, stingy cylinder 16, gear 17, rack piston 18, stepper piston 19, piston rod 20, cylinder 21, the rotation of its arm by rack piston 18 driven gears rotate finish extractings, cut the end, three transpositions of let-down locate, one end of rack piston 18 is the inner chambers that are enclosed within stepper piston 19, and an end of stepper piston 19 is to be enclosed within piston 28 inner chambers.When air pressure passes to the left side, rack piston 18 moves right earlier, utilizes stepper piston 19 to continue to move right, and utilizes the interior sky of stepper piston 19 to carry out the transposition location once, and then pulling stepper piston 19 continues to move right, and carries out transposition location more once by piston seat 28 inner chambers.When air pressure when the right is transmitted, rack piston 18 is moved to the left on earth, carries out the transposition location once more, thereby realizes three transpositions location.The lifting of arm is finished by cylinder 21, and the folding of paw 15 is finished by stingy cylinder 16.Cut the cutter 30 that has under the basic skill or training position by motor 31 driven rotary at robot device 5, after goods were put down by robot device 5, motor 31 drove cutterhead 29 and rotates, and cutter 30 cuts.

The head 3 of present embodiment has two injection ports, cooperate two cover die head device 1, blow molding die devices 2, cut bottle at the bottom of device 4 and robot device 5, can once make two goods.
