Description
Technical field
The present invention relates to plastic bottle blowing molding machine field of mechanical technique, particularly relate to the flexible structure of a kind of limit mould and the bottle blowing machine of bed die linkage.
Background technology
Bottle blowing machine is the equipment in the plastic bottle processing and manufacturing fields such as carafe, oil bottle, medicine bottle, bottle blowing machine includes left and right limit mould and bed die, three cooperatively forms a complete bottle die cavity, during work, within opening left and right limit mould and bed die and bottle base being placed in die cavity, turn off left and right limit mould and bed die, bottle base is carried out blowing processing, opening left and right limit mould and bed die after complete bottle molding to be processed, the bottle after machining is taken away and delivers to next procedure.
The Chinese patent of Patent No. 201220622542.9 discloses the link gear of a kind of bottle blowing machine limit mould and bed die, as shown in Figure 1, 2, including mould bases support 101, drive the folding connecting rod 102 of bottle blowing machine limit mould folding, drive the bed die support 103 of blowing machine bottom mold lifting, also have and connect folding connecting rod and the linkage linkage of bed die support, drive linkage linkage motion while folding connecting rod driven mold folding, and then driven the lifting of bed die support by linkage linkage；Being provided with track base 105 on mould bases support, bed die support connects the slide rail 104 slided in track base；Described linkage linkage includes the fixing connecting rod 106 being fixed on folding connecting rod, the crank 107 being hinged on mould bases support, fixing connecting rod and crank are connected by the two ends of connecting rod 108, and fixing connecting rod is driven by folding connecting rod and drives connecting rod, crank-motion successively；Equipped with the crank slot gusset 109 having curved slot 110 on bed die support, the roller 111 rolled along curved slot it is provided with on crank, crank handle turns roller rolls and to applying the power with vertical direction in the curved slot of crank slot gusset, and then drives crank slot gusset, bed die support motion.
This kind of bottle blowing machine can realize the linkage between limit mould and bed die well, but still there is problems in that as shown in Figure 3, when blown container, bed die stress moves down, but because there is gap d between limit mould 201 and bed die 202, and the part such as bed die support, slide rail, track base, crank, roller and cam is rigid body, will produce bigger internal force between above-mentioned part during relative motion, slide rail and track base that wherein rigidity is poor are easily deformed and wear and tear.Cause slide rail and track base need to shut down replacing, greatly reduce production efficiency, increase cost of equipment maintenance.
Summary of the invention
Purport of the present invention is in the field at Bian Mo and bed die linkage bottle blowing machine, there is provided a kind of and can form, with bed die, the flexible structure buffered by opposite side mould during bottle blowing, to reduce the interaction force of limit mould and bed die connected component, greatly reduce device damage speed, the extension device life-span, and ensure product quality.
Bottle blowing machine limit of the present invention mould and the flexible structure of bed die link gear, including mould bases support, drive the folding connecting rod of bottle blowing machine limit mould folding, drive the bed die support of blowing machine bottom mold lifting, it is hinged with crank on mould bases support, folding connecting rod is by connecting rod connecting crank drive it to rotate, equipped with having the cam of cam curve on bed die support, equipped with the roller rolling along cam curve and driving bed die support vertical to move on crank；Having the special-shaped slot of band arc-shaped above cam curve, be provided with movable block in special-shaped slot, movable block can rotate in the circular arc of special-shaped slot, and when it goes to extreme lower position, its lower surface forms continuous print cam curve with cam；Leave gap between the upper surface of movable block and special-shaped slot, in gap, be provided with the elastomer of elastically deformable.
Bottle blowing machine limit of the present invention mould and the flexible structure of bed die link gear, when bottle blowing machine is filled with compressed gas blown container, bed die stress moves down.Existence because of bed die Yu this gap of mould, limit, and the part such as bed die support, slide rail, track base, crank, roller and cam is rigid body, to produce bigger internal force during relative motion between above-mentioned part, slide rail and track base that wherein rigidity is poor are easily deformed and wear and tear.After arranging flexible structure, the internal rigid impact of above-mentioned part is absorbed by the deformation of elastomer, and this rigid shock is converted into soft impulse by elastomer.By the setting of this structure; significantly reduce the internal force that between bed die, slide rail, track base, crank, roller and cam, rigid body relative motion produces; it is effectively protected slide rail and the deformation of track base, decreases the damage of above-mentioned part; this is conducive to the extension device life-span; improve production efficiency and reduce maintenance cost, advantageously ensuring that product quality.

Detailed description of the invention
A kind of bottle blowing machine limit mould and the flexible structure of bed die link gear, including mould bases support 1, drive the folding connecting rod 2 of bottle blowing machine limit mould folding, drive the bed die support 3 of blowing machine bottom mold lifting, crank 4 it is hinged with on mould bases support, folding connecting rod is by connecting rod 5 connecting crank drive it to rotate, equipped with having the cam 6 of cam curve 7 on bed die support, equipped with the roller 8 rolling along cam curve and driving bed die support vertical to move on crank；Having the special-shaped slot 9 of band arc-shaped above cam curve, be provided with movable block 10 in special-shaped slot, movable block can rotate in the circular arc of special-shaped slot, and when it goes to extreme lower position, its lower surface forms continuous print cam curve with cam；Leave gap between the upper surface of movable block and special-shaped slot, in gap, be provided with the elastomer 11 of elastically deformable.
The center of described elastomer 11 has axis and is perpendicular to the through hole of bed die support 3 direction of motion, and its outer surface pushes against the upper surface of the end face in special-shaped slot and movable block respectively.Elastomer can produce a certain amount of elastic deformation, and when the deformation of elastomer can make the relative motion between parts, stress diminishes；The through hole at center can improve its effective deflection, strengthens buffering effect.
The end face of special-shaped slot 9 is waveform, including two crests of continuous print and a trough；The end face of movable block 10 is the arc that middle part caves inward, its one end pushes against in a crest of special-shaped slot and can rotate in special-shaped slot around this point, elastomer 11 is arranged between another crest of special-shaped slot and the medial recess position of movable block, and the vertical at elastomer axis place is roller and promotes bed die in place of fitting in die cavity with limit mould.Special-shaped slot is wave-like, and one end of movable block end face projection pushes against at the crest of its wave, it is ensured that the rotation of movable block is smooth and easy；And the end face depression of another crest of special-shaped slot and movable block forms the space of a location, elastomer is securely positioned at this.
Fixing equipped with pressing plate 12 on cam 6, the plate face of pressing plate is covered in outside the side of special-shaped slot 9.The setting of pressing plate is positioned in special-shaped groove from side by movable block and elastomer, is conducive to improving its steadiness.
