Abstract

The utility model relates to a machine for blow-moulding plastic bottles, comprising a lathe bed, an electrical control box, a hopper, an injection component, a parison injection mould, a middle toggle plate, a back toggle plate and a back mould plate. The utility model is characterized in that a parison injection mould locking mechanism designs the traditional longitudinal mode-locking into the transverse mode-locking; the middle toggle plate rotates the mold core 180 DEG back and forth to carry out the process of two operating positions injection-blow moulding. A middle toggle plate and a transverse mode-locking mechanism are added on the present injection moulding machine to form a machine for blow-moulding plastic bottles. The utility model has the advantages that the investment is low, the effect is quick, and the purpose of one machine with double purposes are achieved.

Description

Machine for blow-moulding plastic bottle

The utility model belongs to the device with the plastics-production hollow article, the improvement of particularly relevant plastics injection bottle blowing machine.

General plastics injection bottle blowing machine all adopts the rotation of oil pump drive screw to give traditionally and moulds, and oil cylinder is injected, driven mobile mould and opens and closes and carry out locked mode.Make in the barrel plastics through plasticizing by injection member, inject under certain pressure that pressurize, solidify in the core chamber, workpiece is unloaded in die sinking behind cooling forming, then repeat to produce continuously.Can only produce general plastic products in this way, be not suitable for producing small dimension high density polyethylene (HDPE) (HDPE) plastic drug package.

The utility model is at above-mentioned shortcoming, and design reaches with duplex plate, four die sinkings and rotating mould structure annotates blow molding processing.Rotating mould, injection folding mould, middle bracket open-and-close mechanism have been increased, mobile mould is designed to blow molding die, middle bracket is made up of oil cylinder, tooth bar, rotating shaft, rotating mould, detent mechanism, positioning seat etc., keying oil cylinder, tooth bar move, make the 180 ° of back and forth rotations of rotating mould that are fixed on the rotating shaft, thereby the parison on the middle bracket, core are back and forth rotated exchange.

Can carry out the injection moulding processing of various thermoplastics with said method.Steady quality, good seal performance is specially adapted to produce high density polyethylene (HDPE) (HDPE) hollow screw socket, and anti-limit flat plastic products especially are fit to produce small dimension high density polyethylene (HDPE) (HDPE) screw socket Plastic medicinal bottle.And the automaticity height, production efficiency can be enhanced about more than once.

Accompanying drawing 1 is that plastics injection bottle blowing machine master looks diagrammatic sketch

Accompanying drawing 2 is that two stations notes one blow the rotation diagrammatic sketch

Accompanying drawing 3 is parison injection mould cut-away views

Accompanying drawing 4 is middle bracket cut-away views.

Number in the figure is: 1---front template, and 2---biconjugate is opened the interlock template, and 3---the oil cylinder of cranking arm supporting; the middle bracket of 4---moving crank arm seat, 5---opens and closes oil cylinder, 6---the connecting rod oil cylinder of cranking arm; 7---mould adjusting mechanism, 8---the locked mode of cranking arm is adjusted seat, and 9---connecting rod; 10---connecting rod, 11---the supporting of cranking arm, 12---the locking slide block; 13---piston rod, 14---oil cylinder, 15---the guide rail cylinder seat; 16---rotating shaft, 17---top mechanism of qi structure, 18---detent mechanism; 19---oil cylinder, 20---sill, 21---tooth bar; 22---upright arm, 23---the piston pole socket, 24---rotating mould; 25---positioning seat, 26---entablature, 27---cylinder; 28---lathe bed; 29---hopper, 30---articles injection-moulded, 31---the parison injection mould; 32---middle bracket; 33---the back bracket, 34---rear pattern plate, 35---electric control box; 36---core A, 37---core B.

Now in conjunction with the accompanying drawings, the utility model is described in further detail.

The course of work of plastics injections bottle blowing machine is: at first rear pattern plate 34 effects, and vertically will back bracket 33, middle bracket 32 moves to and parison injection mould 31 matched moulds.Open and close the connecting rod oil cylinder 6 of cranking arm this moment, makes the vertically entad motion of seat 4 of cranking arm, and biconjugate opened the template 2 that links vertically lock.Open and close the oil cylinder 14 of connection piston rod 13 simultaneously, with the locking slide block 12 on the piston rod 13 laterally entad move with biconjugate open the interlock template 2 laterally lock.Plastics are injected into biconjugate by articles injection-moulded 30 and open space among interlock template 2 and the core A36 in the hopper 29 at this moment, form parison A.While, opens and closes cylinder 27 and makes 27 couples of parison B of top mechanism of qi structure blowing in the bracket 33 of back at parison B on the core B37, forms goods.And exhaust hood 27 resets, and top mechanism of qi structure 17 also resets, and rear pattern plate 34 moves after resetting and making back bracket 33 vertically, and bracket 32 in the disengaging, take out finished product from the bracket 33 of back.Oil cylinder 14 resets, and locking slide block 12 on the piston rod 13 is unclamped reset.Simultaneously the connecting rod oil cylinder 6 of cranking arm also resets, and drivening rod 9, connecting rod 10 reset, and make biconjugate open interlock template 2 and split, and bracket opens and closes oil cylinder 5 at this moment opening and closing, and bracket 32 moves after vertically and breaks away from parison injection mould 31 in making, and parison A is on core A36.Open and close to connect the oil cylinder 19 of tooth bar 21, tooth bar 21 moves, and driven rotary axle 16 rotates, and the rotating mould 24 that is fixed on the rotating shaft 16 is rotated together, turns to after detent mechanism 18 on the rotating mould 24 hits positioning seat 25, and oil cylinder 19 stops.At this moment, the core A36 in the middle bracket 32 forwards the position of core B37 to, and core B37 forwards the position of core A36 to.Rear pattern plate 34 effects this moment vertically move forward back bracket 33, and bracket opens and closes oil cylinder 5 in the keying, and the core A36 in making on the bracket 32 inserts biconjugate and opens in the interlock template 2, and back bracket 33 moves to the matched moulds position, and rear pattern plate 34 quits work.Open and close the connecting rod oil cylinder 6 of cranking arm, the seat 14 of cranking arm is vertically entad moved, drivening rod 9, connecting rod 10 move, making biconjugate open interlock template 2 closes up, locks, at this moment open and close oil cylinder 14, piston rod 13 is laterally entad moved, the locking slide block 12 locking biconjugates on the piston rod 13 are opened interlock template 2, articles injection-moulded 30 start injections, work is carried out in circulation continuously.

This plastics injection bottle blowing machine is as long as on existing plastic-injection moulding machine, and bracket 32 and horizontal clamping mechanism in the increase can become a novel plastics injection bottle blowing machine, reduced investment, and instant effect reaches the function of dual-use.This plastics injection bottle blowing machine is made with metal material.
