Description

Mould cooling device of tyre shaping vulcanizer

Technical Field

The utility model relates to a tire design vulcanizer technique specifically is a tire design vulcanizer mould cooling device.

Background

At present, when the existing tire shaping vulcanizer in China vulcanizes tires, the temperature of a tire mold is very high, and when the vulcanizer produces tires with different specifications, the tire mold needs to be replaced.

It is a common practice to replace the tire mold by disconnecting the medium (such as high temperature steam, superheated water, etc.) that heats the mold and allowing the tire mold to cool naturally in air.

The method for cooling the tire mold takes long time, has low production efficiency, and cannot meet the requirements of modern production.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model aims to solve the technical problem that an improve production efficiency's tire design vulcanizer mould cooling device is provided.

The technical scheme includes that the tire shaping vulcanizer mold cooling device comprises a mold cooling mechanism, and is characterized in that the mold cooling mechanism comprises a liquid spraying ring pipe with a semicircular section, the liquid spraying ring pipe is welded on the inner wall of the lower part of a lower steam chamber body to form a closed pipeline, the liquid spraying ring pipe is connected with an outdoor cooling liquid inlet pipe through a liquid inlet formed in the lower steam chamber body, and the bottom of the lower steam chamber is connected with an outdoor cooling water return pipe through a liquid return opening formed in the lower steam chamber body; and nozzles for spraying cooling medium inwards and upwards are uniformly distributed on the 1/4 arc-shaped pipe body at the upper part of the liquid spraying ring pipe at the periphery.

In order to expand the spraying range of the cooling medium, a plurality of radial nozzles are arranged on the 1/4 arc-shaped pipe body of the water spraying ring pipe.

The plurality of nozzles are arranged into an upper nozzle, a middle nozzle and a lower nozzle, so that the spraying requirement can be met.

Conventionally, the cooling liquid inlet pipe is arranged at the rear side of the lower steam chamber.

Conventionally, the cooling liquid inlet pipe is provided with a stop valve, a check valve and a filter.

The utility model has the advantages that:

1. the utility model discloses tire design vulcanizer mould cooling device can accelerate the formation of vortex, cools off the mould fast, shortens retooling time, improves work efficiency.

2. The utility model discloses simple to operate, low cost, control is simple, and the practicality is good, is applicable to various tire design vulcanizer.

Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The utility model discloses tire design vulcanizer mould cooling device, be semicircular hydrojet ring canal 2 including the cross-section, hydrojet ring canal 2 welds and forms to the confined pipeline on the inner wall of 1 room body lower parts in lower steam chamber, sets up the inlet that link up in room body rear portion of 1 room body lower part in lower steam chamber corresponding to hydrojet ring canal 2 position, the inner intercommunication hydrojet ring canal 2 of inlet, the outer end of inlet is passed through the coupling and is connected the outer cooling feed liquor pipe of 1 room of lower steam chamber, be equipped with trip valve, check valve and filter on the cooling feed liquor pipe, the liquid mouth has been seted up back to the bottom of lower steam chamber 1, the liquid mouth returns the liquid pipe through the outer cooling of coupling joint room, as shown in figure 1, figure 2, figure 3, figure 4.

The 1/4 arc-shaped pipe body at the upper part of the liquid spraying ring pipe 2 is uniformly provided with nozzles 2-1 for spraying cooling medium inwards and upwards at the circumference, the nozzles 2-1 are an upper nozzle, a middle nozzle and a lower nozzle which are arranged on the arc-shaped pipe body, and all the three nozzles 2-1 are radial ports, as shown in fig. 1, 2 and 3.

The utility model discloses an operation mode does:

1. a sealed vulcanisation environment is formed when the upper steam chamber 3 is inserted down into the lower steam chamber 1.

2. And (3) opening the cut-off valve, enabling a cooling medium (tap water is conventionally adopted) to enter the liquid spraying ring pipe 2 through the cooling liquid inlet pipe, and spraying the cooling medium (tap water) onto the tire mold through the nozzles 2-1 which are arranged on the liquid spraying ring pipe 2 at different angles and are circumferentially and uniformly distributed to rapidly cool the mold.

3. The temperature raising medium after cooling the mould returns to the cooling pipeline system through the cooling liquid return pipe.

4. The cooling medium (tap water) cooled by the cooling pipeline system enters the liquid spraying ring pipe 2 through the cooling liquid inlet pipe for recycling.
