Abstract
The invention discloses an improved oval inner tube vulcanization mold, which is provided with an inner tube vulcanization upper mold 1, an inner tube vulcanization lower mold 2, inner tube vulcanization upper mold die orifice planes 3, 4, 5 and 6, and inner tube vulcanization lower mold die orifice planes 7, 8, 9 and 10, and is characterized in that: after the inner tube vulcanization upper die 1 and the inner tube vulcanization lower die 2 are assembled, the shape of an inner cavity is oval, the oval long axis is in the horizontal direction, the oval short axis is in the vertical direction, the ratio of the long axis to the short axis is 1.05-1.25, the die opening planes 7, 8, 9 and 10 of the inner tube vulcanization lower die 2 rise and are respectively combined with the die opening planes 3, 4, 5 and 6 of the inner tube vulcanization upper die to reach certain pressure, internal pressure steam or wind is filled into an inner tube green tire of the inner cavity, and air of the inner cavity starts vulcanization after the mold assembly between the inner tube vulcanization upper die 1 and the inner tube lower die 2 is expanded and extruded. The inner tube mould cavity is not required to be provided with an exhaust groove or an exhaust line for exhaust, so that the problems of complicated processing of the inner tube mould and difficult mould cleaning, labor waste and material consumption in production are solved, the manufacturing cost is saved, and the appearance quality of a product is improved.
Description
Technical Field
The invention relates to an inner tube vulcanizing mold, and directly relates to an improved oval inner tube vulcanizing mold.
Background
At present, in the inner tire manufacturing industry, gas in an inner tire mold is exhausted through transverse and longitudinal exhaust grooves or exhaust lines on the inner surface of the mold, a large number of exhaust grooves or exhaust lines are added in the inner tire mold of a general enterprise, scars of the exhaust grooves or the exhaust lines are left on the appearance of a product, the appearance quality of a finished product is affected, and the exhaust grooves or the exhaust lines need to be machined again when the mold is used. Therefore, an improved oval inner tube vulcanization mold is developed, air is exhausted without an air exhaust groove or an air exhaust line, and the air exhaust groove or the air exhaust line of the inner tube mold is not required to be machined again in the inner tube production.
Disclosure of Invention
The invention aims to provide an improved elliptical inner tube vulcanization mold, which does not need to be provided with an exhaust groove or an exhaust line for exhaust in a mold cavity of the inner tube mold, solves the problems of complicated processing of the inner tube mold, difficult mold cleaning in production, waste of labor and material consumption, saves the manufacturing cost and improves the appearance quality of a product. The die is simple in structure, convenient to process and use and convenient to produce and manage.
The purpose of the invention is realized as follows: the utility model provides a modified oval inner tube vulcanization mould, has that inner tube vulcanizes and goes up mould 1, inner tube vulcanizes lower mould 2, inner tube vulcanizes and goes up mould die orifice plane 3, 4, 5, 6, and inner tube vulcanizes lower mould die orifice plane 7, 8, 9, 10, characterized by: after the inner tube vulcanization upper die 1 and the inner tube vulcanization lower die 2 are assembled, the shape of an inner cavity is oval, the oval long axis is in the horizontal direction, the oval short axis is in the vertical direction, the ratio of the long axis to the short axis is 1.05-1.25, the die opening planes 7, 8, 9 and 10 of the inner tube vulcanization lower die 2 rise and are respectively combined with the die opening planes 3, 4, 5 and 6 of the inner tube vulcanization upper die to reach certain pressure, internal pressure steam or wind is filled into an inner tube green tire of the inner cavity, and air of the inner cavity starts vulcanization after the mold assembly between the inner tube vulcanization upper die 1 and the inner tube lower die 2 is expanded and extruded.
The inner die cavity of the inner tube vulcanizing die is oval after die assembly, the raw tire is better vulcanized by matching with the die after being inflated with internal air, the exhaust is facilitated, the problems of complex processing of the inner tube die, difficulty in die cleaning in production, waste of labor and material consumption are solved, the manufacturing cost is saved, and the appearance quality of a product is improved. The die is simple in structure, convenient to process and use and convenient to produce and manage.
