Abstract
The invention relates to a downward adjustable mould for a giant tyre, an upper mould is fixedly positioned on an upper supporting plate of a vulcanizing machine or tank, lower steel rings of a lower mould are fixedly installed on a lower mounted plate of the vulcanizing machine or tank, an outer mould is fixedly mounted on the lower steel rings, adjustable blocks are circumferentially arranged around the circumferential portion of the lower mould, a plurality of guide sliding chutes are evenly arranged on the inner side surface of the outer mould, a lower mould plate is positioned on the inner ring of the lower steel rings, and gib blocks on the back portion of the adjustable block are inserted into the guide sliding chutes and arranged above the circumferential margin of the lower mould plate. In mould clamping time, the upper mould plate falls down with a top bridge of the vulcanizing machine or tank to press the adjustable blocks and the lower mould plate to go down with the upper mould plate, and the adjustable mould is in a radial-axial movement along the guide sliding chutes to mutually fold, forming a mould cavity with the upper mould plate and the lower mould plate. In mould opening time, a cylinder of the adjustable mould jacks up the lower mould plate and the adjustable blocks. The mould satisfies the requirements of vulcanizing and shaping a zero-angle giant tyre, a centering mechanism which is engaged with the upper mould plate and the outer mould is convenient in centering, being used to form a complete set together with the vulcanizing machine or tank, the adjustable blocks move flexibly and accurately, and the segregated structure of the outer mould is convenient in arrangement, adjustment and maintenance.
Description
(1) technical field
The present invention relates to tyre adjustable die, particularly jumbo tyre bottom-open type adjustable die.
(2) background technology
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.Usually the activating mold of version, active block is installed with the upper beam of equipment with die sleeve and is connected, during die sinking, with the fixing activating mold of putting the beams in place by segmented mold operating mechanism ejection active block, the axial and radial motion of the downward do of active block is opened.And, adopt segmented mold vulcanizedly for the giant-scale engineering radial-ply tyre, and then the weight of a decorative pattern module is just nearly one ton, and this just makes that the manipulation strength of open-close module is big, dyskinesia.And the activating mold of version can only be applicable to vulcanizer usually, and can not be used for vulcanizing tank.
(3) summary of the invention
The objective of the invention is to design a kind of jumbo tyre bottom-open type adjustable die, its active block is installed on counterdie, and the active block unfolding mode is from bottom to top, does axially and radial motion, is called for short bottom-open type.Active block is radial and axial to be moved flexibly, and matched moulds centering accurately, reliably can be general on vulcanizer and two kinds of vulcanizing equipments of vulcanizing tank.
The jumbo tyre bottom-open type adjustable die of the present invention's design comprises upper die and lower die and active block, and patrix comprises cope match-plate pattern and mounting plate, and cope match-plate pattern is installed under the mounting plate, and mounting plate is connected with the entablature of vulcanizer or vulcanizing tank.Counterdie comprises outer die casing, lower bolster, lower steel ring and bottom plate, lower steel ring is installed on the bottom plate of vulcanizer or vulcanizing tank, and medial surface is that the outer die casing of back taper is installed in lower steel ring, and the active block of 16～24 identical sizes of piece is around being installed on the lower bolster periphery; Cope match-plate pattern, lower bolster and the active block that closes up into circumference constitute the die cavity of tire during matched moulds, the outer die casing medial surface is evenly equipped with 16～24 guide chutes corresponding with active block, on lower bolster is installed in and encircles in the lower steel ring, there is the gib block that matches with guide chute at the back of each active block, the gib block of active block is inserted in the guide chute of outer die casing, is positioned at lower bolster circumferential outer edge top.On the face that active block and cope match-plate pattern are in contact with one another wearing plate is installed all, the two forms a pair of pair of friction components.With on the lower bolster face that contacts of active block wearing plate is installed also.The seam that cooperatively interacts is arranged between cope match-plate pattern and the active block, and die parting line of the two and horizontal plane have 4～6 ° angle on the seam.
Cope match-plate pattern is equipped with the centering body that cooperates with outer die casing, as guide post, and perhaps wedge.
During matched moulds after patrix and the counterdie centering, cope match-plate pattern descends with the entablature of vulcanizer or vulcanizing tank, mold clamping force is with the wearing plate pressing of cope match-plate pattern and active block, form the transmission that friction pair guarantees power, cope match-plate pattern compressing active block and lower bolster therewith descend, when descending, segmented mold moves radially to the center along oblique guide chute, close up mutually, also form friction pair between the bottom surface of active block and the wearing plate of lower bolster, final cope match-plate pattern, lower bolster and each active block that closes up into circumference constitute the forming cavity of tire, finish matched moulds.The sulfuration mold clamping force is finished by the plunger case that vulcanizer adds power cylinder or vulcanizing tank.Segmented mold oil cylinder piston bar jack-up lower bolster and active block from bottom to top during die sinking, active block is done axially and radial motion from bottom to top along guide chute, and pair of friction components guarantee that active block moves steadily, finishes die sinking up and down.
The advantage of jumbo tyre bottom-open type adjustable die of the present invention is: 1, this activating mold is satisfied with the all-steel giant radial 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 applicable to supporting with the central authority of vulcanizer, or the capsule clamping device of using with vulcanizing tank is supporting; 2, outer die casing and active block and equipment underbeam are connected and installed, and active block is to do from bottom to top axially and radial motion is opened during die sinking, and under the cooperation of gib block and guide chute, each active block piece moves flexibly accurately, guarantee the sulfuration quality of finalizing the design; 3, the friction pair between the wearing plate of active block and bolster, the exactly of the transmission of assurance mold clamping force and the radial and axial displacement of active block; 4, the centering body that cooperates between cope match-plate pattern and the outer die casing is convenient to accurate centering, thereby guarantees that matched moulds puts in place; 5, the split-type structural of outer die casing and active block is convenient to install, adjusts and is safeguarded.
