Description

The tire-mold cleaning device of double-deck hydraulic vulcanizing press

Affiliated technical field

The utility model relates to a kind of tire-mold cleaning device, and the tire-mold that this device is used for double-deck hydraulic vulcanizing press cleans.

Background technology

Tire-mold in use, its die cavity needs cleaning regularly because of the pollution of deposition.At present, known cleaning device has two class devices of mechanical ablution and chemical cleaning method.The former generally is devices such as electrical grinding machine, sand-blasting machine, dry ice machine, and this method exists abrasive material to stop up steam vent, and has shortcomings such as labour intensity is big or time-consuming.The latter use simple dress chemical solvent the hydrojet case, connect supply line, sprinkler head etc. when using, though mould is had corrosion, and liquid is restive when cleaning, cleaning environment, operator there is pollution, but its cleaning is easy, and running cost, equipment investment are all low, still are widely used.In addition also have advanced ultrasonic cleaning equipment, laser cleaner, but investment is high, is not also accepted extensively by market at present.

The tire-mold of double-deck hydraulic vulcanizing press cleans and generally adopts chemical cleaning method, and it has dual mode, and the one, vulcanizer is concentrated outward and is cleaned, though clean conveniently, and overcome the environmental pollution of production scene, the workload of dismounting, transhipment mould is bigger.Another kind of is that sulfuration board supernatant is washed, but solvent liquid is open when the water cleaning die die cavity of production scene, and just there is very major injury in the solvent that flies upward to cleaning personnel and field apparatus, thereby contaminated environment, operating efficiency is low simultaneously, and water consumption is big, easily influences adjacent operation.

Summary of the invention

In order to overcome the shortcoming of existing tire-mold Chemical cleaning---be that machine concentrates the cleaning amount big outward, board supernatant contaminate dyes environment, the deficiency that operating efficiency is all low.The utility model provides a kind of cleaning device, and this device can be washed at sulfuration board supernatant, pollutes and water consumption but can reduce site environment, improves operating efficiency, and simple being suitable for.

The technical scheme that its technical problem that solves the utility model adopts is: after mold cavity spray chemical liquids, mould is in closure state, close the seal device by adding at mould steel ring place, add ring-like water injector in the mold cavity, utilize sulfuration pipeline, the curing medium-inner cold water of vulcanizer, circumferentially each site pressure to mold cavity of formula is sprayed water, after solvent liquid converges in die cavity, most cleaning fluid is concentrated discharging by this device again, and little part is only by the die venting hole and discharges on the spot.

Gasket set and ring-like water injector: every cover gasket set constitutes by identical two groups, the inside and outside two parts of every component, and inside is divided into rubber seal; The outside is divided into steel bushing, and screw hole is arranged on the steel bushing.Ring-like water injector is formed by ring-like pipe and water-in and water-out silk guide rod assembly welding, and each circumferentially, respectively directly upwards is distributed with many apertures ring-like pipe; Water inlet silk guide rod has only the sealing ring end to offer aperture, tyre spiral shell mosquito, the equal blow-by of both ends of the surface; Water outlet silk guide rod all has aperture near the two ends, the end face seal of ring-like pipe end, and the sealing ring end is the spiral shell mosquito in addition.The steel bushing of gasket set cooperates with the spiral shell mosquito of the water-in and water-out silk guide rod of ring-like water injector, can regulate the centre distance of two rubber seal, and being convenient to adapt to specification difference is not that very big mould cleans; All to have aperture be the importing that adds big flood to water-in and water-out silk guide rod and draw at the sealing ring end; The end face seal of the ring-like pipe end of water outlet silk guide rod is to guarantee that water must spray to die cavity in the ring-like pipe, the aperture of the water outlet silk guide rod of ring-like pipe end guarantees that the water in the die cavity converges thus and derives, thereby makes the water under high pressure of sealing finish the single cycle cleaning in mold cavity.

The beneficial effects of the utility model are: whole cleaning process is simple suitable, fully closed, high pressure type hydroblasting, the cleaning efficiency height, and on-the-spot controlled pollution is little.Simultaneously Clean-give, draining is convenient, cleaning device mainly is the existing tyre vulcanization pipe network that utilizes vulcanizer.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: 1. medium is into and out of control valve, 2. Pressure gauge, 3. tire-mold bearing flat plate, 4. water-in and water-out flexible pipe, the 5. upper and lower mould of tire-mold fixed head 6. tires, 7. ring-like water injector, 8. gasket set, 9. mould entery and delivery port.

The specific embodiment

In Fig. 1 embodiment, rinse water is used high pressure type inner cold water, and the curing medium by vulcanizer is finished cleaning into and out of pipe network at mold cavity.Promptly the medium by series connection advances valve into and out of the inner cold water of control valve (1), the water supply hose of water-in and water-out flexible pipe (4), water inlet by mould entery and delivery port (9) enters in the mold cavity, in mold cavity, circulate, derive by the delivery hose of water-in and water-out flexible pipe (4) by the delivery port of mould entery and delivery port (9) again, discharge into and out of the exhaust-valve of control valve (1) by medium again, finish the cleaning of mould.

In Fig. 2 embodiment, rinse water enters an end gasket set (8) by the water inlet of mould entery and delivery port (9), enter ring-like water injector (7) again, make press water be ejected into mold cavity, form flushing, most of water converges by ring-like water injector (7) again in the die cavity after the flushing, is derived by the delivery port of mould entery and delivery port (9), and the fraction water in the die cavity is then directly discharged by board on the spot by the steam vent of mould.

In Fig. 3 embodiment, rinse water is entered by an end rubber seal mouth of gasket set (8), the end holes of the water inlet silk guide rod by ring-like water injector (7) and aperture are introduced, enter its ring-like pipe again, spray to mold cavity by the aperture on the ring-like pipe, most of water in die cavity aperture of the ring-like pipe end of the water outlet silk guide rod by ring-like water injector (7) again converges, by water outlet silk guide rod, by the aperture and the end holes of water outlet silk guide rod sealing ring end, arrive the rubber seal mouth of the other end and discharge.
