Description

VESSEL FORM FOR VULCANIZATION OF CONSOLIDATED TAPES

It was filed on August 23, 1961 No. 742496 / 23-4 to the Committee on Inventions and Discoveries under the Council of Ministers of the USSR

Published in the “Bulletin of inventions .N 13 for 1962

A known mold for the vulcanization of rim bands on tires on presses, comprising a base and a cover. For this, however, it is necessary to use profile blanks that are created manually (cutting, spreading, glue and joining rim tape blanks).

The purpose of the invention is to reduce the use of manual labor, to facilitate the loading and unloading of molds and to ensure the use of rubber regenerate. For this, a mold is proposed in which a sliding part is installed between the base and the lid mounted on the heated surfaces of the table and the traverse of the tress. The sliding part of the mold is provided with a steam jacket along the outer contour and rollers to move it along the guides of the brackets attached to the frame of the press.

The drawing shows the proposed mold in two projections.

The mold consists of a base / and cover 2 mounted on a table 5; traverse 4 presses; a middle sliding part 5 provided with a steam jacket 6 along the outer contour and rollers 7 for moving it along the guides 8; Brackets I attached to the frame 10 of the press.

All parts of the mold have cylindrical protrusions 11 for centering and matching. The inner surfaces of the base and the sliding part are made in the shape of the product.

Mold works as follows.

After heating the mold to 167-170 ° C, lay the workpiece and automatically raise the base 1 up.

With the help of the centering pins and the cylindrical lock (flange), the middle half of the part 5 is picked up and carried upwards up to the cover. As soon as all three main parts of the latex form begin to come into contact, the rim tape is pressed and vulcanized; the pressure of the press is 100-120 tons. The press is equipped with control and electrical devices, after vulcanization of the rim tape, it opens automatically.

Subject invention

A mold for vulcanizing rims of tires on presses, including the base and the lid, characterized in that, in order to reduce the use of manual labor, ease the loading and unloading of the mold and ensure the use of rubber regenerate, between the base and the lid mounted on the heated table surfaces and press traverse, a mold retractable part is installed, provided with a steam jacket along the outer contour and rollers to move it along the guide brackets attached to the press frame.
