Abstract

The invention relates to a fixed connection push board of a lower mold plate of a giant tire adjustable mold. The bottom parts of various patterned mold blocks are articulated with a slide block which is arranged between the lower mold plate and the push board and is embedded in a radial slide groove; and a link rod is articulated with a lower mold sleeve at the back of various patterned mold blocks. The patterned mold block back is provided with an upper inclined plane and a lower inclined plane or an upper inclined arc surface and a lower inclined arc surface, and an upper mold sleeve and the lower mold sleeve are provided with an upper fixing ring and a lower fixing ring of an inner polygonal cone surface which is matched with the upper inclined plane and the lower inclined plane or provided with an upper cone surface and a lower cone surface which are matched with the upper inclined arc surface and the lower inclined arc surface. When the mold is locked, the push board and the lower mold plate drive the slide block and the patterned mold block to move downwards; the patterned mold block controlled by the link rod withdraws downwards and inwards to closely contact the tire surface periphery; the slide block connected with the bottom end slides inwards along the slide groove; the upper mold sleeve move downwards to press the patterned mold block to further withdraw downwards and inwards and an spigot of the upper mold sleeve and the lower mold sleeve are closed; and then the mold locking is completed. Then the mold is opened by a reverse movement. The adjustable mold meets the requirements of giant tire sulfuration and shaping and is applicable in sulfuration machines and sulfuration tanks; the patterned mold block moves flexibly and accurately, which guarantees the quality of sulfuration and shaping.

Description

Giant tire activating mold

(1) technical field

The present invention relates to tyre adjustable die, particularly giant tire activating mold.

(2) technical background

Tyre adjustable die is the critical equipment of tyre vulcanization, the decorative pattern module that activating mold comprises upper die and lower die and can move radially.The giant tyre diameter is big, section is wide, decorative pattern is dark, the also corresponding increasing of the size of its mould, weight.Just nearly one ton of the activating mold of common version, the weight of a decorative pattern module, this just makes that the manipulation strength of open-close module is big, dyskinesia.Therefore this activating mold can only be applicable to vulcanizer, and can not be used for vulcanizing tank.

(3) summary of the invention

The objective of the invention is to design a kind of giant tire activating mold, its decorative pattern module is installed on counterdie, moves radially flexibly, and matched moulds centering accurately, reliably.

The giant tire activating mold of the present invention design comprises Upper Die-sleeve and is installed on the cope match-plate pattern of Upper Die-sleeve, lower die-sleeve and be installed on the lower bolster of lower die-sleeve, and the decorative pattern module of the identical size of N piece is around being installed on the lower bolster periphery, N=16～40.Cope match-plate pattern, lower bolster and the decorative pattern module of closing up into circumference constitute the die cavity of tire during matched moulds, it is characterized in that, the lower bolster affixed push pedal in bottom, the bottom of each decorative pattern module and a slide block outer end are hinged, slide block is between lower bolster and push pedal, be embedded in the radial groove of push pedal, hinged 1～4 connecting rod in the back side that each decorative pattern module is outside, the connecting rod other end is articulated in lower die-sleeve.Be that intilted tapered plane down in bottom or declivity cambered surface, upper rear portion are the intilted upward tapered plane in upper end or go up oblique cambered surface bottom each decorative pattern module back side, when the decorative pattern module back side is up and down during tapered plane, the last retainer plate that the interior N pyramidal surface that matches with tapered plane on the decorative pattern module is arranged under the Upper Die-sleeve has the following retainer plate of the interior N pyramidal surface that matches with tapered plane under the decorative pattern module on the lower die-sleeve.When the decorative pattern module back side was last declivity cambered surface, die sleeve was that the internal conical surface up and down that is mated is arranged up and down.

During matched moulds, push pedal and lower bolster drive slide block, the decorative pattern module moves down, each decorative pattern module is inwardly drawn in and is adjacent to the tyre surface circumference under the effect of connecting rod, Upper Die-sleeve moves down then, because of the end opening of last retainer plate external diameter greater than decorative pattern module top, last retainer plate covers on outside the decorative pattern module, the downward slippage of ramp along the decorative pattern module back side, compressing decorative pattern module, the lower inclined plane at the decorative pattern module back side is reclining the inner conical surface of retainer plate to glide, and lower bolster and push pedal move down, and each decorative pattern module is further also inwardly closed up downwards, the slide block that its bottom connects is along the inside slippage of chute, the last lower inclined plane at its back side is fitted with the inner conical surface of retainer plate up and down, die sleeve closure up and down, and matched moulds is finished.During die sinking, Upper Die-sleeve moves on cope match-plate pattern, decorative pattern module top is unfettered, push template on push pedal is stressed, move in lower bolster and the push pedal, drive on slide block, the decorative pattern module and move, simultaneously under the control of connecting rod, slide block moves outside chute, and mould is opened in the outside translation of the relative tire of each decorative pattern module.

Be connected with spring between slide block the inner and the push pedal, be convenient to slider displacement.

The interface of die sleeve has the seam that cooperatively interacts up and down, and Upper Die-sleeve and lower die-sleeve seam closure during matched moulds guarantee that die sleeve centering is accurate up and down.

Up and down after the die sleeve closure, each bottom, decorative pattern module top and gapped between the die sleeve up and down, pressure hour when unloaded or in the capsule, die sleeve supports mold clamping force up and down, and each decorative pattern module holding capacity is not avoided its damage.

The advantage of giant tire activating mold of the present invention is: 1, this activating mold is satisfied with the giant tyre sulfuration typing requirement of major diameter, wide section, as can be used for section width and reach the sulfuration typing that 27 inches, rim diameter reach 49 inches 27R49 giant tyre, and can be used for vulcanizer and vulcanizing tank; 2, under the effect of slide block and connecting rod, each decorative pattern module moves flexibly accurately, guarantees sulfuration typing quality; 3, the seam of die sleeve cooperation makes centering easy up and down, and guarantees that decorative pattern module, bolster matched moulds put in place; 4, push away in the push pedal and make that to unload tire convenient and strength-saving; 5, the die sleeve closure supports mold clamping force up and down, avoids the fail in compression of decorative pattern module.
