Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described in detail.

[0038] exist figure 1 , 2 Among them, the tire vulcanizing machine 1 of this embodiment includes: a lower table 3L on which the lower mold part 2L is mounted, an upper table 3U on which the upper mold part 2U is mounted, and the above-mentioned upper table 3U is supported so as to be able to move up and down in a lowered position. P1 ( image 3 , 4 shown) the lifting unit 4 for closing the upper and lower mold parts 2U and 2L, and the mold fastening unit 5 for fastening the upper and lower mold parts 2U and 2L at the lowering position P1.

[0039] As said upper and lower mold part 2U, 2L, it does not specifically limit, The mold of a well-known structure can be used suitably. E.g Figure 7 (A), Figure 7 As illustrated in (B), the lower mold portion 2L of this example includes a lower mold 6 corresponding to the lower sidewall portion and the lower bead portion of the tire T, and a h...

Abstract

The invention addresses the problem of tightening a mold evenly and with good precision over long periods. This tire-curing press (1) is equipped with: a lower table (3L) on which the lower mold section (2L) is installed; an upper table (3U) on which the upper mold section (2U) is installed; a hoisting means (4), which supports the upper table to move up and down freely; and a mold-tightening means (5), which tightens the mold at the lowered position. The hoisting means is equipped with a clamping mechanism (19). The mold-tightening means is equipped with: a connecting implement (30), which has tie rods (32) that connect the upper and lower tables; and a pressurizing implement (31) that has a ring-shaped pressurizing plate (41), which is disposed to slide vertically inside a ring-shaped groove (40) that provides a recess on the lower table and on the upper surface of which the lower mold section is installed.

Description

technical field [0001] The present invention relates to a tire vulcanizing machine capable of performing fastening of upper and lower mold parts in a balanced and high-precision manner over a long period of time, and capable of stably ensuring a large fastening force. Background technique [0002] Patent Document 1 below proposes a tire vulcanizing machine using a crank mechanism. Such as Figure 8 As shown, this tire vulcanizing machine includes a lower table b1 on which a lower mold part a1 is mounted, an upper table b2 on which an upper mold part a2 is mounted, and a lifting unit c that supports the upper table b2 in a liftable manner. In addition, a crank mechanism e is employed as the above-mentioned elevating unit c. The crank mechanism e includes: a crank gear e1 rotatably supported by the two side frames d; a side groove e2 provided in the vertical direction of the two side frames d; The slide block e3 and the connecting rod e4 connecting the above-mentioned crank ...
