Description
Technical field
The utility model relates to a kind of link gear that can drive the bed die lifting on bottle blowing machine when driving the mould bases folding.
Background technology
Be distributed with a plurality of moulds for the moulding plastics bottle on bottle blowing machine, this mould generally comprises left mould, right mould and bed die, described left mould, right mould and bed die can be separated or close up under the driving of separately driving mechanism, being embodied as the closure or openness of mould, thus can feed station place opening mold with the bottle embryo is put into its die cavity, in shaping station place close die to take out and to be transported to subsequent processing with the bottle embryo blow molding in shape chamber and at bottle outlet station place opening mold with the plastic bottle with moulding.Therefore, the motion of accurately controlling left mould, right mould and bed die is the key factor that can blow moulding machine produce plastic bottle smoothly.
as Fig. 1, shown in 2, it is the structural representation of major part of a kind of bottle blowing machine of prior art, it comprises the mould that is arranged on the bottle blowing machine frame, mould forms the left mould 103 of die cavity when closing up, right mould 104 and bed die 105 form, its left mould 103, right mould 104 is arranged on left mould bases 101 and right mould bases 102 and drives it by left mould bases 101 and right mould bases 102 and separates in the horizontal direction or close up, 105 of bed dies are arranged on the bed die support and drive it by the bed die support and separate or close up with right mould 104 with left mould 103 in vertical direction, the separating and close up by folding mould device and control of left mould bases 101 and right mould bases 102, the vertical direction of bed die support moves and is controlled by lowering or hoisting gear, wherein, folding mould device is to drive the folding roller by its cooperation that is arranged on the folding roller 107 on its folding idler-wheel connecting-rod 106 and is fixed on the folding pattern cam 108 on the bottle blowing machine frame to connect pavilion 106 and swing, thereby the arm shaft (not shown) that makes folding idler-wheel connecting-rod 106 drive side fixed thereon swings to drive mould bases folding kinematic link (not shown), and then order about mould bases folding connecting rod (not shown) by mould bases folding kinematic link and impel left mould bases 101 and 102 horizontal movements of right mould bases, the left mould 103 of final drive and right mould 104 are separated or close up.Lowering or hoisting gear drives the bed die support by the lifting roller 109 that is arranged on the bed die frame bottom and the cooperation that is fixed on the lifter cam 110 on the bottle blowing machine frame and slides up and down along the slide rail that is fixed on the mould bases support, make bed die 105 separate or close up with left mould, right mould at predetermined station, thereby realize the separation of mould or close up.
but when working due to bottle blowing machine, mould bases support 111 on it, be arranged on the left mould bases 101 on mould bases support 111, right mould bases 102, the bed die support, and folding mould device is all around the rotating shaft High Rotation Speed of bottle blowing machine, and adapt for the rotating speed with bottle blowing machine, lowering or hoisting gear also need to drive the bed die support with and on the bed die fast lifting, therefore, the bottle blowing machine of prior art usually can there are the following problems: 1, in the process that the bed die support descends, the bed die support is under the downward thrust of top spring 112, the lifting roller 109 of its lower end is in a flash inconsistent with the elevated surfaces of the curved surface of lifter cam 110, and lifting roller 109 from the turning of lifter cam 110 be transitioned into low site surface in a flash, lifting roller 109 can produce with the curved surface of lifter cam 110 shock of larger intensity, and its impact strength strengthens with the quickening of its rising or falling speed, and this shock can produce larger noise on the one hand, produce noise pollution, on the other hand, easily cause hard and crisp roller cracking to occur because of shock.2, the larger lifter cam of volume 110 need to be set separately and coordinate to drive the lifting of bed die support drive bed die with lifting roller 109, will inevitably strengthen the volume of bottle blowing machine, take more space.3, because bottle blowing machine runs up, so its dimension precision requirement to lifter cam 110, and the lifting roller 109 of bed die support and the assembling quality of fit between lifter cam 110 require all very high, otherwise can affect the normal operation of bottle blowing machine, therefore, it can bring larger difficulty to the work such as making, technique and installation of lifter cam, strengthens production cost.
Summary of the invention
The purpose of this utility model is to provide a kind of link gear that can realize mould bases folding and the bed die lifting of bottle blowing machine, it can reduce bottle blowing machine shared space, improve the service life of bottle blowing machine, and the stability of bottle blowing machine operation, but and decrease noise.
the link gear of mould bases folding and the bed die lifting for bottle blowing machine described in the utility model, comprise and at the driving lower swing of drive unit and to drive the folding mould connecting rod of the mould bases folding of bottle blowing machine, there is an end of oscillating bearing connecting rod to be connected with folding mould connecting rod, the other end of oscillating bearing connecting rod is connected with the slide block that can be arranged on horizontally slidingly on the mould bases support, be fixed with on slide block and drive seat, for being fixed with the bed die lifting guide plate with height fall curve slideway on the bed die support that drives the bed die lifting, drive and be connected with the driving shaft that its end can be stretched into curve slideway and can slide on seat in curve slideway, folding mould connecting rod swing and when driving the mould bases folding, but driving joint bearing connecting rod band movable slider horizontal slip, thereby with the driving seat horizontal movement on movable slider, and then make the drive shaft bed die lifting guide plate vertical direction that stretches in curve slideway move to drive the lifting of bed die support.
but the utility model is owing to being connected with the oscillating bearing connecting rod of the slide block horizontal slip of drive installation on the mould bases support on folding mould connecting rod, and be provided with curve slideway and the driving shaft that matches being fixed on the bed die lifting guide plate on the bed die support and being fixed on driving seat on slide block, this bed die lifting guide plate is supported by driving shaft, when rotating under the driving of folding mould connecting rod at drive unit with when driving the mould bases folding, the link motion of folding mould guide rod driving joint bearing, to promote slide block horizontal slip on the mould bases support, thereby it is mobile to drive the driving seat, so that sliding in curve slideway and drive bed die lifting guide plate, the driving shaft of driving seat moves up and down, and then make bed die lifting guide plate order about bed die lifting on bed die support and bed die support, realize the folding of mould bases and the lifting interlock of bed die.Therefore, compared with prior art, the utlity model has following beneficial effect: 1, can drive simultaneously mould bases folding and bed die lifting by driving the rotation of folding mould connecting rod, and the lifter cam that large volume need not be set on bottle blowing machine coordinates to drive the lifting of bed die support drive bed die with the lifting roller, therefore, can effectively reduce the volume of bottle blowing machine, improve the space availability ratio of workshop.2, slide in curve slideway under the driving of oscillating bearing connecting rod when driving shaft and drive in the process of bed die lifting guide plate lifting, driving shaft offsets with the sidewall of curve slideway all the time, can not produce shock, but the decrease noise intensity, and the service life of improving corresponding component.3, rotate by driving folding mould connecting rod the mode that drives simultaneously mould bases folding and bed die lifting, more easily guarantee its quality of fit, can reduce the difficulty of making, technique and the installment work of corresponding component, reduce production costs.
