METHOD OF TIRE VULCANIZATION AND TIRE VULCANIZATION APPARATUS
A technology for tire vulcanization that simplifies the structure of a lower container through avoiding of the electrical wiring and air piping for detaching a vulcanized tire from the lower container and enables use of simple operation parts, such as hydraulic cylinder and air cylinder, in a segment mold opening-and-closing unit provided on an upper container to thereby realize simplification of the segment mold opening-and-closing unit and reduction of equipment cost. There is provided a method of tire vulcanization comprising the tire insertion step of inserting green tire (G) in lower container (11) at tire supply position (A); the tire vulcanization step of carrying out vulcanization molding of the green tire (G) between the lower container having moved to tire vulcanization position (B) and upper container (10) having moved from ascent position (Y) to descent position (X) at the tire vulcanization position; the container departing step of moving the upper container to the ascent position while leaving the vulcanized tire in the lower container; and the tire takeout step of drawing out the vulcanized tire from the lower container having moved to tire takeout position (C). Further, there is provided a relevant tire vulcanization apparatus.
A tire vulcanization apparatus that realizes not only reduction of operation steps as compared with the prior art through, in the insertion and setting of a green tire in a lower container, direct insertion and setting of a green tire taken and retained at a tire loading position in a lower container but also simplification of a tire vulcanization apparatus through avoiding of a tire lifting and lowering unit capable of ascending and descending at a tire supply position, thereby attaining a reduction of equipment cost. The tire vulcanization apparatus comprises tire loading unit (5) capable of reciprocation in a horizontal direction between tire supply position (A) and tire loading position (P) adapted to take and retain green tire (G) at the tire loading position and perform insertion and setting of the green tire (G) in lower container (11) at the tire supply position (A).
A method of tire vulcanization in which a tire detaching unit does not need to have ascending/descending function, and in which even when the ascending/descending is conducted, the ascending/descending stroke is shortened, thereby reducing the height of tire vulcanization apparatus as a whole and rendering the apparatus compact. The method of tire vulcanization comprises the steps of (S2) lifting vulcanized tire (T) obtained by vulcanization molding of green tire (G) to ascent position (D) at tire vulcanization position (Y) by means of upper container (30); (S3) moving tire detaching unit (20) to the tire vulcanization position; (S4) lowering the upper container from the ascent position (D) to tire delivery position (B) and causing the tire detaching unit to hold the vulcanized tire; (S5) opening the upper container at the tire delivery position; and (S6) lifting the upper container having released the vulcanized tire from the tire delivery position to waiting position (C).
[PROBLEMS] To arrange the stroke region of a piston lower in comparison with before by such a structure as a tapered portion formed on the inner circumferential surface at the opening of a cylinder case can be included in the piston sliding surface, and to provide a piston valve which can be made compact by forming the cylinder case to have a lower profile in comparison with before thereby lowering the overall height of the piston valve while reducing the cost by decreasing the hardening area on the inner circumferential surface of the cylinder case. [MEANS FOR SOLVING PROBLEMS] A tapered portion (17) for guiding insertion of a piston (10)isformed at the opening of a cylinder case (14) having the inner circumferential surface formed as the piston sliding surface (13).

The tire vulcanizing apparatus is one comprising superior container (10) with a superior die fitted via platen (13) to support plate (11) and inferior container (20) with an inferior die fitted via platen (23) to support plate (21) so that raw tire (T) set between the superior and inferior dies is vulcanized and molded by indirect heating of the containers by the heat from the platens, wherein each of heat insulating members (12,22) is disposed between the relevant platen and support plate in such a fashion that each of heat insulating air layers (11a,21a) is provided between the relevant heat insulating member and platen, or between the relevant heat insulating member and support plate.
This invention provides an apparatus for cooling a tire after vulcanization, which, by blowing cooling air while rotating a tire after vulcanization, can realize uniform cooling and shortening of the time for cooling the vulcanized tire and can prevent deformation of the vulcanized tire caused by the centrifugal force of the vulcanized tire.
