Description

TECHNICAL FIELD [0001] The present invention relates to a condenser drain device for a tire vulcanizer,

The present invention relates to a device for discharging condensate of a tire vulcanizer, which is capable of improving the quality of an article tire by uniformly maintaining the temperature inside the bladder by discharging condensed water generated during vulcanization of the green case.

Generally, pneumatic tires are manufactured by mixing semi-finished products such as a cacass, a tread, a belt layer, an inner liner, etc. by mixing the rubber, A green case is made, the green case is put into a mold, and a certain temperature and pressure are applied to produce a finished tire.

The manufacturing process of the pneumatic tire includes a refining process for producing a compounded rubber by mixing synthetic rubber, natural rubber, reinforcing material and various additives; A semi-finished product manufacturing process for manufacturing various semi-finished products using the produced compounding rubber; A cutting process for producing semi-finished products in a predetermined standard; A forming step of forming the cut semi-finished product into a green case; A vulcanizing step of applying the heat and the pressure to the green case to produce the finished tire; And inspecting the quality of the finished tire.

In the vulcanizing step, steam is supplied to the inside of the green case to apply a constant temperature and pressure, and sulfur is added to harden the rubber component of the tire, thereby strengthening the tire.

1, the green case 60 is inflated at a constant temperature and pressure in the green case 60 provided inside the mold of the vulcanizer 50, The bladder 51 uses steam to expand the bladder 51 and regulates the pressure inside the bladder through the supply and discharge of the steam.

Accordingly, in the conventional tire vulcanizer, heat and pressure are supplied using the steam supplied into the bladder 51 through the vulcanizer post 55. When the vulcanization of the green case 60 is completed, The steam is discharged through the discharge port 52 'formed in the condensate cylinder 52 of the steam generator 50.

Since the discharge piston valve 54 is turned off when the green case 60 is vulcanized, the internal pressure of the bladder 51 and the pressure to the front end of the discharge piston valve 54 are the same, The condensed water stored in the condenser 52 is not discharged. When the green case 60 is completely vulcanized, the discharge piston valve 54 is opened, thereby causing a pressure difference between the discharge piston valve 54 and the discharge piston valve 54. Therefore, And is discharged to the outside through the discharge pipe 53 together with the steam inside the steamer 51.

However, in the above-described conventional tire vulcanizer, steam and condensed water are not discharged during the vulcanization of the green case, and consequently, condensed water remains in the condensate tube. Therefore, And a temperature deviation is caused in the upper and lower parts of the green case under vulcanization, so that uniform vulcanization can not be carried out, thereby deteriorating the quality of the finished product tire.

On the other hand, Patent Document 1 discloses a tire mold having a heating conduit in which a discharge connector is connected to an outlet of a heating conduit, and a longitudinal axis of the discharge connector is positioned below a longitudinal axis of the heating conduit, Lt; / RTI >
