[background technology]
At present, the processing of injecting, drawing and blowing plastic by one-step method hollow container both at home and abroad, adopt three stations or four stations to annotate the stretch blow blow moulding machine mostly, because its station is many, mold component is corresponding supporting more, processing, assembly precision to mould and equipment require height, and this just certainly will increase the manufacturing cost and the production cost of products of main frame and mould.Granted publication number improves for the notes stretch blow blow moulding machine of the patent of invention of CN2649318Y " two work station one-step rotation injection blowing bottle machine " to traditional " three stations ", " four stations ", take the scheme of two stations, overcome the manufacturing cost and the high problem of production cost of products of main frame and mould basically.But the moving plate that is somebody's turn to do " two work station one-step rotation injection blowing bottle machine " drive core lifting is placed between upper mounted plate and the support, injection mould and bottle blowing mould are placed on the support, if support is lower, can make troubles to operation, if the rising support must make complete machine become huge.This machine adopts and is inserted into the formula oil cylinder and adds and be inserted into the pad post or machinery is carved piece locking injection mould and bottle blowing mould in addition, and not only structure is complicated, and operating process is also complicated.
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of simple in structure, easy to operate double-station reciprocating rotary type injection stretch blow blow moulding machine, traditional " three stations ", the main frame of " four stations " notes stretch blow blow moulding machine existence and the high and high problem of production cost of products of manufacturing cost of mould can be overcome, above-mentioned " two work station one-step rotation injection blowing bottle machine " existing weak point can be overcome again.
The technical scheme that solves the problems of the technologies described above is: a kind of double-station reciprocating rotary type injection stretch blow blow moulding machine, comprise main frame and mould two major parts, described main frame partly comprises frame, be horizontally fixed on the worktable panel on the frame, place the injecting systems of horizontal positioned on the frame, injection moulding clamping system perpendicular to the worktable panel setting, lie in a horizontal plane in blowing matched moulds system and vertically disposed stretching device on the worktable panel, injection moulding station and stretch-blow station are 180 ° of symmetrical distributions, ° finish injection moulding and stretch-blow exchange station by the reciprocal Rotate 180 of rotating mechanism;
Described injection moulding clamping system comprises cope match-plate pattern, worktable panel, lower bolster, Mode-locking oil cylinder, guide pillar, be installed in the rotary drive mechanism on the cope match-plate pattern, the rotating disc and the oil cylinder of loosing core, lower bolster is connected with cope match-plate pattern by the guide pillar that vertically passes worktable panel, Mode-locking oil cylinder is fixed on the worktable panel below, its tailpiece of the piston rod is fixedlyed connected with lower bolster, lower bolster can move up and down along with the flexible of Mode-locking oil cylinder piston rod, thereby driving cope match-plate pattern does, the following reciprocating motion, rotating disc is installed in the middle part, lower surface of cope match-plate pattern, and rotary drive mechanism is installed in the top of cope match-plate pattern and is rotationally connected with rotating disc;
Described mould part comprises that symmetry is installed in an identical mouth module I of the following square structure of rotating disc and a mouthful module II, and corresponding with mouth module I center is the core group that is connected with the oil cylinder piston bar of loosing core and fixedly connected with hot flow path and be installed in injection module on the worktable panel; Corresponding with mouth module II center is the stretching module that passes cope match-plate pattern, and is installed in the blowing module in the middle of the blow-molding system.
In initial state, cope match-plate pattern and mouthful module I, a mouthful module II are positioned at and are up to bit position, core group that is connected with the oil cylinder of loosing core and the sealing cylinder in the stretching device and draft cylinder also all are in the tip position of cope match-plate pattern top, the bottle mould of blowing module is in opening, and core group, mouthful module I, injection module and hot flow path are in the same side and constitute the injection station; Stretching module, mouthful module II and bottle mould are in opposite side and constitute the stretch-blow station;
Rotating disc drives mouthful module I under the driving of rotary drive mechanism and a mouthful module II does back and forth to rotate 180 ° of intermittences, finishes injection moulding and stretch-blow exchange station.
Its further technical scheme: described blowing matched moulds system comprise structure identical about two die cylinders and matched moulds plate, two guide rods that play the guiding balanced action are equipped with in die cylinder cylinder body both sides, guide rod one end links to each other with the matched moulds plate, the adjustment screw of the position-limiting action the when other end has been equipped with and has regulated die cylinder and run to the center, thus die cylinder drives the flexible open and close that drives left and right sides matched moulds plate and bottle mould of guide rod.
Described stretching device comprises stretching support, sliding seat, draft cylinder and sealing cylinder; The stretching support is fixedly mounted on the cope match-plate pattern, sliding seat is installed in the stretching mid-stent, sealing cylinder is installed in a top of the trellis that stretches, the sealing cylinder tailpiece of the piston rod is fixedlyed connected with the top of sliding seat, draft cylinder is installed in the sliding seat top, the draft cylinder tailpiece of the piston rod is connected with the stretching bar of stretching module by contiguous block, the stretching module seal the bottom that piece is fixedly mounted on sliding seat, the sealing cylinder piston rod drives draft cylinder and seals piece and pumps along the stretching support, and the draft cylinder piston rod drives contiguous block and the stretching bar pumps.
Further technical scheme is: the mouth module I and mouthful module II of described mould part comprise n mouthful of mould, 1 group of Hough board component and 1 mouth mould cylinder respectively, the injection module comprises n die and 1 die socket, and described blowing module comprises 1 group of bottle mould that contains n die cavity; The described core group that is connected with the oil cylinder piston bar of loosing core comprises n core; The described stretching module that is connected with stretching device comprises that n root stretching bar and n piece seal piece;
N the core of n die cavity of n the mouth mould of above-mentioned mouth module I and mouthful module II, n die of injection module, bottle mould, core group and the n root stretching bar of stretching module, the value that the n piece seals the n in the piece are identical, and the span of n is: n is the arbitrary integer in 1~20.
Mouthful mould cylinder directly drives the Hough plate and a mouthful mould carries out the open and close action, by alignment pin and limited block realize the hole mould in and position-limiting action.
After goods blowing was finished, its stripping means was: open blow molding die earlier, a mouthful module II is being with goods up openings at one side mould cylinder on one side, and this moment is because the stretching bar still keeps stretching out state, and the goods both sides lose constraint and drop voluntarily, afterwards the draft cylinder original position of withdrawing again.
