Abstract

The invention discloses a radial tire vulcanization mold for a common shaping vulcanizer. The mold is composed of an upper template, a lower template and an active module located at the crown of the tire mold. The upper template uses a connecting piece and a flexible module The outer cover of the opening and closing mold is connected as a whole, and the lower formwork is connected and fixed with the vulcanizing machine table. The active module has a cone and matches the inner cone of the outer cover. The active module is opened by moving the outer cover up and down. Clamping moves. The invention has the advantages of simple structure, convenient and accurate mold opening and closing operation, and does not need the active module operating mechanism necessary for the radial tire vulcanizer, so that the radial tire vulcanization can be carried out on the ordinary vulcanizer, thereby greatly reducing the processing cost.

Description

Radial tire vulcanization mold for ordinary shaping vulcanizer

technical field

The invention relates to a mold of a vulcanizing machine in tire production, in particular to a radial tire vulcanizing mold used on a common setting vulcanizing machine.

Background technique

In the prior art, due to the limitations of its structure and function, ordinary tire shaping and curing machines are usually only used for ordinary, middle and low-end tire curing and shaping, and cannot be vulcanized and shaped for higher varieties of radial tires. For the radial tires that have become more and more popular at present, the vulcanization setting needs a vulcanizing machine with an active module operating mechanism. The active module moves up and down with the opening and closing of the vulcanizing machine. This kind of operating mechanism is powerless. If the enterprise wants to change from ordinary tires to radial tires, to update products and increase varieties, it often needs to purchase new radial tire vulcanization equipment, and the original ordinary setting vulcanizers are either idle or will be scrapped. This situation is undoubtedly a great waste and loss for business operators.

Contents of the invention

The present invention aims at the above-mentioned problems existing in the prior art and proposes a radial tire vulcanization mold used on a common vulcanizing machine. The machine is used for radial tire vulcanization production.

In order to solve the above-mentioned technical problems, the common vulcanizing machine radial tire vulcanization mold of the present invention is composed of an upper template, a lower template and an active module located at the crown of the tire, wherein the outer surface of the active module is made into a cone, the The cone is matched with the inner cone of an outer sleeve used to open and close the flexible module. The outer sleeve is connected with the upper template by a bolt connection, and can be moved up and down with the vulcanizing machine. The formwork is connected and fixed with the vulcanizing machine. In order to separate the active module from the lower formwork when the mold is opened, a separation groove and a spring are set between the active module and the lower formwork.

In the above-mentioned radial tire vulcanization mold, the upper side template connected with the outer sleeve as a whole moves up and down with the opening and closing of the vulcanizing machine table. When moving downward, the outer sleeve makes the movable module inward for mold clamping through the action of the conical surface. Move; when moving upward, the jacket constraint of the active module is released, and the mold opening movement is completed by the action of the separation groove and the spring. The radial tire vulcanization mold of the present invention has the characteristics of simple structure, convenient operation, and no special requirements for ordinary vulcanizers, and realizes the purpose of vulcanizing radial tires with ordinary vulcanizers. The modular operating mechanism greatly reduces the production cost of radial tire vulcanization.

Detailed ways

According to the common stereotyped vulcanizer radial tire vulcanization mold shown in Figure 1, it is divided into an upper template 2, a lower template 1 and an active module 4 located at the crown of the tire mold. 9 is connected and fixed, and the upper side formwork 2 is connected as a whole with a bolt connector 6 and an outer sleeve 3 for opening and closing the flexible module 4 . A part of the outer surface of a fan-shaped block is made into a conical body 8, and the inner body of the outer sleeve 3 has an inner conical surface that matches the conical body 8 of the active module 4, and the inner conical surface of the outer sleeve 3 can be movably placed in the active module 4. On the cone body 8; on the lower template 1, there are T-shaped slots 7 in the radial direction according to the circumference, and cooperate with the corresponding T-shaped blocks located under the active module 4, and a separation spring is installed in the T-shaped slot 7 5. The two ends act on the active module 4 and the lower template 1 respectively.

When the integrated outer sleeve 3 and the upper template 2 are started to move downward by the vulcanizing machine, the inner cone surface of the outer sleeve 3 matched with the conical body 8 moves the active module 4 inward for mold clamping, Together with the upper template 2 and the lower template 1, the radial tire vulcanization cavity is formed. After the vulcanization process is completed, the vulcanizer lifts the upper template 2 and its outer sleeve 3, and the active module 4 is connected to the lower side under the action of the separation spring 5. The template 1 is separated, thereby completing the vulcanization of the radial tire.
