The patent No. be 201220622542.9 Chinese patent disclose the link gear of a kind of bottle blowing machine limit mould and bed die, as shown in Figure 1, 2, comprise 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 the interlock linkage connecting folding connecting rod and bed die support, drive the motion of interlock linkage while the folding of folding connecting rod driven mold, and then drive bed die support to be elevated by interlock linkage; Mould bases support is provided with track base 105, bed die support is connected with the slide rail 104 slided in track base; Described interlock linkage comprises the stationary links 106 be fixed on folding connecting rod, be hinged on the crank 107 on mould bases support, stationary links is connected with the two ends of crank by connecting rod 108, and stationary links is driven by folding connecting rod and drives connecting rod, crank-motion successively; The crank slot gusset 109 having curved slot 110 bed die support is equipped with, crank is provided with the roller 111 rolled along curved slot, crank handle turns roller rolls and to applying with the power of 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 interlock between limit mould and bed die well, but still there is following problem: as shown in Figure 3, when blown container, bed die is stressed to be moved 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 larger internal force during relative motion between above-mentioned part, the slide rail that wherein rigidity is poor and track base are easily out of shape and wear and tear.Cause slide rail and track base to shut down replacing, greatly reduce production efficiency, increase cost of equipment maintenance.
Summary of the invention
Purport of the present invention is in linking in the field of bottle blowing machine at Bian Mo and bed die, there is provided a kind of and opposite side mould and bed die can form the flexible structure cushioned in bottle blowing process, 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.
The flexible structure of bottle blowing machine limit mould of the present invention and bed die link gear, comprise 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, mould bases support is hinged with crank, folding connecting rod is by connecting rod connecting crank and drive it to rotate, and bed die support is equipped with the cam having cam curve, crank is equipped with and rolls along cam curve and to drive the roller that bed die support vertical moves; Have 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 and cam form continuous print cam curve; Leave gap between the upper surface of movable block and special-shaped slot, in gap, be provided with the elastomer of elastically deformable.
The flexible structure of bottle blowing machine limit mould of the present invention and bed die link gear, when bottle blowing machine is filled with Compressed Gas blown container, bed die is stressed to be moved down.Because of the existence in bed die and 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 larger internal force during relative motion between above-mentioned part, the slide rail that wherein rigidity is poor and track base are easily out of shape and wear and tear.After arranging flexible structure, the internal rigid of above-mentioned part is impacted and is absorbed by elastomeric deformation, 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; the distortion of effective protection slide rail and track base, decrease the damage of above-mentioned part; this is conducive to the extension device life-span; enhance productivity and reduce maintenance cost, being conducive to ensureing product quality.
