Abstract
The utility model discloses a limiting stopper in radial tire activating collaterals mold. The mold includes a guide strip and a guide ring capable of sliding and being limited on the guide strip, wherein a sliding chute that does not penetrate the guide strip body is provided along the length direction of the guide strip, the limiting stopper on the guide ring and the sliding chute end constitute a limiting structure between the guide ring and the guide strip, the limiting stopper is a split type structure, composed of circular nuts and T-bolts meshed with the circular nuts, grooves for incomplete embedding of the nuts are provided on one surface of the guide ring facing to the sliding chute, stepped bolt holes are provided on the guide ring, the T-bolts are provided in the bolt holes and are connected to the circular nut.
Description
Technical field:
The utility model relates to the limited block in the segmented mold of radial tyre, belongs to the production mould technical field.
Background technology:
At present, the domestic mould that is used to produce high-grade radial mainly is an activating mold, its operation principle is by forming to concentric mechanism and die cavity, in conjunction with Fig. 1, mould is included in the tapered plane guiding and produces the lead ring 3 of enough mold clamping force effects, adorns pattern block and drive pattern block 7 does sliver 5 (Fig. 3 A, 3B, 3C), slide block 6, loam cake 1, base 2, the limited block 4 that the radial axle stamen moves, compositions such as upper and lower sidewall plate 8,9.Existing known limited block (Fig. 4 A, 4B) is an overall structure, is the bolt of step axle as the screw rod position, and its mounting means is a thread mill drilling on lead ring 3 at first, after limited block 4 directly is installed on the lead ring, the leading section of limited block protrudes in the inclined-plane of lead ring.Because during die sinking, under the effect of vulcanizer, lead ring 3 moves upward, limited when the chute 51 of sliver 5 slides into the chute end when limited block, drive slide block 6, pattern block 7 liftings simultaneously.Because the deadweight and the quiet effect of inertia of slide block and pattern block, this process will produce sizable shearing force, and this shearing force acts directly on the screw thread of limited block leading section, the stop portion that often causes connecting thread on the limited block to be extruded gross distortion even front end in operation process is cut off, limited block can't be removed replacing, not easy-maintaining.Thereby make troubles to production, also fallen at the end simultaneously mould just with the life-span with increased the maintenance and repair cost.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide the novel limited block in the segmented mold of radial tyre, under the prerequisite that guarantees instructions for uses such as its position-limiting action and working strength, guarantee when die sinking, connecting thread not to be pushed gross distortion even its positive stop end is fractureed, and change easily because of the effect that is subjected to shearing force.
The utility model technical solution problem adopts following technical scheme:
Limited block in the loose mould of radial ply tire, described mould comprises sliver, and can on sliver, slide and limited lead ring, its length direction of sliver upper edge offers the chute that does not connect the sliver body, the end of being fixed in limited block on the lead ring and chute constitutes the position limiting structure between described lead ring and the sliver, described limited block is a split-type structural, reaching the T type bolt that matches with round nut by round nut constitutes, described lead ring is provided with the groove that not exclusively embeds for described nut towards the one side of described chute, lead ring is provided with the step bolt hole, and described T type bolt is located in the described bolt hole and with described round nut and is connected.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The designed technical scheme of the utility model is: under the prerequisite that guarantees instructions for uses such as limited block bottom position-limiting action and working strength, former limited block is set to split-type structural, because of its stress surface on the chute end of the face of cylinder of limited block round nut and sliver, guarantee when die sinking, the extruding of limited block connecting thread not to be caused gross distortion even fracture because of the effect that is subjected to shearing force, can be under the prerequisite that guarantees the limited block instructions for use, prolong its service life, fall the maintenance and repair cost of bottom die, and simple in structure, easily realize.
Description of drawings:
Fig. 1 is the existing activating mold structural representation of producing tire; Fig. 2 A is the sliver front view; Fig. 2 B sliver right view; Fig. 2 C sliver vertical view; Fig. 3 A is known limited block front view; Fig. 4 A is a round nut front view in the utility model limited block; Fig. 4 B is the vertical view of Fig. 4 A; Fig. 5 is known limited block assembling schematic diagram; Fig. 6 is the utility model limited block installation diagram schematic diagram.
Number in the figure: 1 loam cake, 2 bases, 3 lead rings, 4 limited blocks, 5 slivers, 51 chutes, 6 slide blocks, 7 pattern blocks, 8 upper sidewall plates, 9 lower fetal pleurons, 10 round nuts, 11 is T type bolt, 12 bolts hole.
The specific embodiment:
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
[0011]
The specific embodiment, non-limiting examples is as described below:
Embodiment: in conjunction with Fig. 2 C, Fig. 5, offer screwed hole on the existing lead ring 3, limited block 4 is connected on the lead ring 3 by screwed hole, the inclined-plane that the leading section of limited block 4 protrudes in lead ring 3 is in the chute 51 of sliver 5, in conjunction with Fig. 1, during die sinking, lead ring 3 rises, when limited block 4 limited when the chute 51 of sliver slides into the end of chute, sliver promptly drives slide block 6, pattern block 7 rises, because the deadweight and the quiet effect of inertia of slide block and pattern block, this process will produce sizable shearing force at the front end of limited block 4, the thread segment of limited block be damaged be difficult to dismounting and change.
In conjunction with Fig. 6, the technical solution of the utility model is that original limited block is set to split-type structural, limited block reaches the T type bolt 11 that matches with round nut by round nut 10 and constitutes, and offers the bolt hole 12 of step on lead ring 3, is used to install T type bolt; Correspondingly, the contacted one side of lead ring and sliver is provided with groove and not exclusively embeds for round nut 10, a part that is round nut 10 embeds in the groove, the inclined-plane that a part protrudes in lead ring 3 is in the chute 51 of sliver, so as outstanding part can and the end of chute form position limiting structure between lead ring and sliver.During die sinking, lead ring 3 slides on sliver 5, and is limited when round nut 10 slides into the end of chute 51, and the shearing force that is produced acts directly on the external cylindrical surface of round nut 10, has protected helicitic texture, even damaged also easy dismounting and change.
