Description
The present invention relates to a tire mold preheating system, and more particularly, to a tire mold preheating system for preheating a mold used for tire vulcanization.
In general, in order to manufacture a tire, a rubber compounded with various rubbers and chemicals is mixed with a semi-finished product through a compression process and a rolling process, and then various semi-finished products are assembled in a molding process to form a green tire in a predetermined shape, The tire is finished with a curing process that chemically bonds the compounded rubber with heat and pressure.
In this vulcanization process, the green tire is inflated through the bladder loaded inside, and the outer surface of the green tire is adhered to the tire by receiving heat and pressure through the mold.
Accordingly, in the tire vulcanization process, the tire mold is required to be preheated, and conventionally, the tire mold is preheated in such a manner that water vapor is used as a heat source, but the rubber mold is brought into contact with the lower surface of the mold through the metal plate.
On the other hand, according to this method, there is a disadvantage that the temperature inside the mold can not be uniformly preheated, and there is a problem that it is difficult to preheat the mold at a high temperature due to a large heat loss.
Further, there arises a problem that further preheating is required in the curing process after the preheating.
It is therefore an object of the present invention to provide a tire mold preheating system capable of preheating a desired portion of a tire mold to a desired temperature.
According to an aspect of the present invention, there is provided a tire manufacturing method comprising: a body portion forming a preheating space in which a tire mold introduced from the outside is preheated; A transfer unit for supplying the tire mold to the preheating space or for releasing the tire mold from the preheating space; A first coil part provided inside the preheating space and movable in a height direction of the body part and preheating the tire mold through induction heating; A lowering module for lowering the first coil part so that the first coil part surrounds the tire mold when the tire mold flows into the preheating space; A preheating module for controlling a preheating amount or a preheating time of the first coil part while the first coil part surrounds the tire mold; And a control module including a lift module for raising the first coil part when the preheating of the tire mold is completed.
The apparatus may further include a second coil part provided on the preheating space to preheat the upper portion of the tire mold.
The second coil part is provided movably along the height direction of the preheating space, and the lowering module includes the second coil part such that when the tire mold flows into the preheating space, the second coil part is adjacent to the tire mold, It is preferable to lower it.
The apparatus may further include a third coil part provided between the transfer part and the tire mold to preheat the lower part of the tire mold.
The third coil part may further include a refractory material enclosing an outer surface of the transfer part, wherein the transfer part protrudes from the outer surface of the transfer part and protrudes through the refractory material and supports the load of the tire mold desirable.
In addition, an opening / closing part for opening or closing the preheating space may be formed on one side of the body part, and the transferring part may be introduced into or removed from the preheating space through the opening / closing part.
Preferably, the opening and closing part includes a first opening and closing part and a second opening and closing part formed on one surface facing the first opening and closing part, and the conveying part moves to the first opening and closing part after passing through the second opening and closing part.
It is preferable that the lowering module adjusts the lowering position of the first coil part so that the first coil part faces the central part of the tire mold.
Preferably, the control unit sequentially operates the descending module, the preheating module, and the ascending module.
In addition, it is preferable that the first coil portion has a diameter of 1320 mm or more.
According to the present invention, the tire mold can be uniformly preheated to a high temperature.
Further, the preheating process of the tire mold can be automated.
Further, the time required for preheating the tire mold can be shortened, and the productivity of the tire can be improved.
