Abstract
The utility model provides a guide meridian type detachable mould with double prick surface, which comprises an upper plate, a lower plate, a detachable block which is equally distributed along the cycle, a guide bar which is arranged at the detachable block and fixedly connected with the detachable block, and a guide ring which matches with the guide bar; the utility model is characterized in that: the matching side of the guide bar and the guide ring is a part of the circular conical surface, which means that the matching side of the guide bar is the outward protruding part of the circular conical surface, while the contact surface of the guide ring is the inside sunken part of the circular conical surface. The guide device of the meridian type detachable mould uses the centering performance of circular conical surface, solves the centering of the whole meridian type detachable mould, and eliminates the centering adjustment of the planes by the pane guide, therefore, the production, the process, the installation, the debugging and the maintenance and service etc. are very simple and convenient and has a high precision.
Description
Affiliated technical field
The utility model belongs to the radial manufacturing technology; Be specifically related to improvement to the radial segmented mold.
Background technology
At present, also there are a certain distance in sub-materialization rate of domestic tire and developed countries, according to incompletely statistics, the comprehensive meridian rate of domestic tire is about 45%, wherein tyres for passenger cars comprises that imported product is 100%, and truck tyre is 40%, and Off-the-road tire and agricultural vehicle tire are 0 substantially; And developed country abroad, what have has then reached 100%.Exist the reason of this gap to have a lot, the backwardness of process technology equipment is exactly an one of the main reasons wherein.Radial sulfurization technology equipment has two kinds of mechanical vulcanizer and hydraulic pressure vulcanizing machines, and these two kinds of machines all more uses segmented molds to come moulding, and in whole process of production, it directly has influence on production work efficiency and end product quality.Segmented mold is a kind of novel tyre sulfuration model of studying the sixties in last century successfully, is applicable to that the belt angle is bigger, the not expansive radial of fetus diameter when typing and sulfuration.It generally is according to the situation of the different equal portions of tyre tread, is divided into some secter pats.Each secter pat can slide up and down along the guide groove of constant slope on the lead ring and radial expansion under the effect that drives cylinder.Closed up the back and constituted a complete die cavity with last lower sidewall mould.Employing cylinder and spring that the driving mechanism of segmented mold has, the utilization that also has drive the cavity that forms between lead ring and the model and fill in air or other media, and lead ring is driven as piston.The emphasis that slip between the spigot surface of driving lead ring and segmented mold and matching requirements are segmented mold generally adopts planar guide.Domestic normally machining production of planar guide segmented mold, be that first machinery processes the one piece tyre pattern ring, then the pattern ring that processes is cut into nine fritters---active block, again active block is carried out facing-up, be contained in the complete segmented mold of composition on the general particular manufacturing craft behind the facing-up.Its planar guide ring also is to adopt machining to form, and processes deviation a little, will make to concentric mechanism centering property badly, and the perishable meeting of spigot surface causes wearing and tearing and poor fit, makes action ineffective.This plane segmented mold is complex structure not only, involves great expense, and maintenance difficult, precision are not high, is used for producing the tire quality after often can not guaranteeing to vulcanize, so percent defective height, waste raw material.External segmented mold has planar guide, also has cylinder to lead; Their structure, technology and operation principle and above-mentioned domestic segmented mold are basic identical.
Summary of the invention
The purpose of this utility model is to provide a kind of good to neutrality, simple in structure for addressing the above problem, machining accuracy height, bipyramid face guiding radial segmented mold easy to maintenance.
For achieving the above object, the utility model is a kind of bipyramid face guiding radial segmented mold of realizing like this, comprises upper plate, lower plate, along the active block that circumference is divided equally, be installed on the described active block and the gib block of fixedlying connected, the guide collar that cooperates with described gib block with active block; The mating surface of above-mentioned gib block and guide collar is arranged to the part of taper seat, and promptly the mating surface of gib block is the part taper seat of evagination, and the contact-making surface of guide collar is the part taper seat of indent.
The taper seat of the evagination of above-mentioned each gib block of fixedlying connected with each active block is the taper seat of the sustained height of same tapering circular cone.
The taper seat of the indent of above-mentioned guide collar is identical with the tapering of the taper seat of the evagination of above-mentioned gib block, and with the taper seat of the evagination of this gib block be the taper seat of sustained height.
Advantage and effect
The gib block of this radial segmented mold adopt evagination taper seat a part and guide collar adopts the part of the taper seat of indent with matching; Utilize performance in fixed that taper seat self had, extraordinary solved whole radial segmented mold to neutrality.And saved with complicated to the neutrality adjustment between each face of planar guide, thus from the production and processing to Installation and Debugging and maintenance etc. all very simple, convenient, and precision height.And this radial segmented mold when having adopted ingenious so simple design also to solve former planar guide in case the aggravation wearing and tearing that corrosion etc. occurred and the problem of poor fit occur, owing to adopt the guiding design of the self-centering of double cone curved surface, matching problem can not occur even corrosion occurs yet, not improve greatly so can not produce local wearing and tearing anti-wear performance therefrom yet.
Description of drawings
Accompanying drawing 1 is the main cutaway view of an examples of implementation radial tire of the utility model segmented mold.
Specific embodiment
As shown in Figure 1, a kind of bipyramid face guiding radial segmented mold comprises upper plate 1, and lower plate 2 has between upper plate 1 and the lower plate 2 and places the cavity that the tire tire is accompanied; Evenly be provided with 9 active blocks 3 along upper plate 1 and lower plate 2 outer marginal circumferences, there is required decorative pattern behind the tire building these active block 3 inboards, be installed on each active block 3 and fixedly connected 9 gib blocks 4 with active block 3, each gib block 4 usefulness is similar to the dovetail groove form and cooperates a guide collar 5; After tyre vulcanization finishes like this, for can the demoulding, need earlier each active block 3 horizontal openings are opened upper plate 1 again, the radial that vulcanizates could take out smoothly; The cooperation that the action of each active block 3 horizontal openings utilizes above-mentioned gib block 4 and guide collar to be similar to the dovetail groove form is finished, concrete action is that guide collar 5 is moved up, guide collar 5 is slided in groove, because gib block 4 vertical directions can not move, so guide collar 5 just drives the gib block horizontal motion, and gib block 4 is fixedlyed connected with active block 3, so also just drive active block 3 horizontal movements, when guide collar 5 moved to the summit, active block 3 was just all opened.
The mating surface of gib block 4 and guide collar 5 all is parts of taper seat, and promptly the mating surface of each gib block 4 is parts of the taper seat of evagination, and the contact-making surface of guide collar 5 is parts of the taper seat of indent.
Decide neutrality in order to increase, the taper seat of the evagination of each gib block 4 is sustained height taper seats of same tapering circular cone.The taper seat of the indent of guide collar 5 is identical with the tapering of the taper seat of the evagination of gib block 4, and with the taper seat of the evagination of this gib block 4 are taper seats of sustained height.
