Vulcanizing press for tires
The present invention relates to vulcanizing press for tires.
Existing this vulcanizing press for tires is just like the vulcanizing pree shown in Figure 22 and Figure 23 (along the view of the arrow D direction among Figure 22).
Among Figure 22 and Figure 23, the body frame 21 of this tire pressurization sulphur machine is to be made of upper frame 21a, lower frame 21b and two side framework 21c, 21d, lower mold 23 is fixed on the lower frame 21b by counterdie installation component 22, with 23 of this lower molds then and make can free folding upper mold 24 be fixed on the patrix installation component 25, fixing the end of the piston rod 27 of two hoist cylinders 26 on the sidepiece that is installed in upper frame 21a on the patrix installation component 25.And, between the both sides of patrix installation component 25 25a, 25b and two side framework 21c, 21d, installing guide member 28.This guide member 28 is made of the roller 30 that is installed in the track strip 29 on side framework 21c, the 21d and be installed on sidepiece 25a, the 25b of patrix installation component 25, advance on the running face 29a of the track strip of processing through high-accuracy mechanical 29 by roller 30, patrix installation component 25 just can face toward counterdie installation component 22 vertical lift freely.And on patrix installation component 25, erectly installing pressurization and transmitting bar 31, the top of bar 31 is transmitted in this pressurization, inserts and by being installed in hollow pressurization oil cylinder 32 inside on the upper frame 21a regularly.
Below, the action of above-mentioned vulcanizing press for tires is described.
By the piston rod 27 that dwindles hoist cylinder 26, patrix installation component 25 is risen, thereby upper mold 24 is risen, then, the tire of not slaking is put in the lower mold 23.
The elongation of the piston rod 27 by making hoist cylinder 26 descends patrix installation component 25, and upper mold 24 is descended, and makes two metal dies, 23,24 closures.Then,, pressure is delivered to pressurization transmits on the bar 31, mould is closed pressurization by making 32 actions of hollow pressurization oil cylinder.
When mould is closed the pressurization end,, patrix installation component 25 is risen by the piston rod 27 that dwindles hoist cylinder 26.Then, the tire that will vulcanize with loading machine outputs to outside the machine, makes the sulfuration end of job, with loading machine the tire of new not slaking is put in the lower mold 23, begins the sulfuration operation of next tire.
The vulcanizing press for tires of above-mentioned prior art is that the guide member 28 that is made of roller 30 and track strip 29 is installed between both sides 25a, the 25b of patrix installation component 25 and two side framework 21c, the 21d two in the localities.
As a result, just must be installed in the depth of parallelism adjustment of 28 of these two guide members in the localities, still, because under the situation of vulcanizing press for tires, be accompanied by heat of vulcanization and cause thermal deformation, thereby this adjustment be difficult.Because the installed surface of guide member 28 on patrix installation component 25 and side framework 21c, 21d increases, therefore just the problem that machined surface is increased and make cost up is arranged again.
Existing vulcanizing press for tires is also driven disclosed vulcanizing pree in clear 58-71143 number just like the Japanese patent gazette spy.
This vulcanizing press for tires is fixed on lower mold on the bottom in the body frame of frame-like, simultaneously upper mold is installed on the downside of lifting platform (patrix installation component), and lifting platform can be supported in the body frame free lifting.On the other hand, the mould pressue device is fixed on the top of body frame, can be installed in the side to the adjusting pad that is clipped in this mould pressue device and be between the lifting platform of down position with keeping out of the way.
Thereby, when upper and lower metal die being pressurizeed, because of adjusting pad is clipped between mould pressue device and the lifting platform by the mould pressue device, to give plus-pressure by this adjusting pad and lifting platform, and when the upper and lower metal die of folding, adjusting pad is avoided to the side, make the lifting platform lifting.
Generally, the vulcanizing press for tires so-called vulcanizing pree of type in pairs on two groups of metal sulphide die devices, installing mould pressue device (mold closing mechanism) in addition respectively and laterally be set up in parallel.
Vulcanizing press for tires in the past, owing to need installing to have adjusting pad with the roughly the same length of lifting travel of lifting platform, thereby the lengthening just of the length on the above-below direction of body frame, the problem that whole vulcanizer is maximized is arranged.
And the paired vulcanizing press for tires of type because in molding cycle (about 15 minutes now), cure time (in the matched moulds) is long, not the slaking tire pack into and the take-off time of tire (load, discharge time) short, mold closing mechanism just is unsuitable for shared.
Now, the cure time in the vulcanizing press for tires is shortening, and might make loading, discharge time lengthening in the future, but in this case, the running efficiency of mold closing mechanism reduces then is a problem, and cost is reduced.
Open flat 2-127409 discloses a kind of vulcanizing press for tires to the open communique of Japanese Utility Model in fact, and wherein, guide member includes guide that is contained on the patrix installation component and the guide rail that is contained on the body side frame.For being slidingly matched, easily cause serious wearing and tearing between this guide and the guide rail.
