Problems solved by technology

[0012] However, the tire vulcanizing device 1 of the above-mentioned conventional structure is a device that makes the elevating/sliding mechanism 10 slide back to the standby position, and sends and feeds the tire between it and the lower die 3, but in the vulcanizing position , the pressurizing cylinder 21 arranged below pulls the connecting rod 13 to pressurize the green tire in the metal mold
However, in this pressur

Embodiment Construction

[0048] Next, one embodiment of the tire vulcanizer of the present invention will be described based on the drawings.

[0049] Figure 1~4 The shown tire vulcanizer 1A is a device that puts a green tire into a die that can be separated into a lower die 3 and an upper die 4 , heats and presses it, and vulcanizes it into the final shape of a finished tire. In addition, in order to form the inner shape of the tire, an air bag (not shown) is disposed inside the mold.

[0050]This tire vulcanizer 1A is installed on a base member 2 fixed to a foundation. A fixed lower mold 3 and a moving trolley 14 capable of moving back and forth in the horizontal direction are provided on the base member 2 . In addition, the lifting / sliding mechanism 10A of the upper mold 4 and the pressurizing cylinder mechanism 30 are provided on the moving trolley 14, and can move integrally.

[0051] In addition, the tire vulcanizer 1A of the present embodiment includes a slide-back mechanism. For example ...

Abstract

In a tire vulcanizing apparatus in which a lift and slide mechanism is slidable back to an evacuation position, an upper die can uniformly exert a pressing force during a vulcanizing process. The tire vulcanizing apparatus (1A) for processing a green tire into a complete-tire shape by inserting the green tire in a die separable into a lower die (3) and an upper die (4) and heating and pressing the green tire, wherein the slide mechanism is provided so that the upper die (4) separated and lifted from the lower die (3) can be reciprocated by linear slides (14) between a vulcanizing position at which the upper die (4) is pushed toward the lower die (3) fixed to a base (2) and an evacuation position at which the green tire is placed between the upper die (4) and the lower die (3) and is taken out after being formed into a complete tire, and the upper die (4) is installed under a beam (11); with a lift cylinder mechanism (30) therebetween, the beam (11) being integrated with tie rods (13) which is movable upward and downward along guide holes of the linear slides (14) by operations of the lift cylinders (12).

Description

technical field [0001] The invention relates to a tire vulcanizing device for vulcanizing and forming tire blanks. Background technique [0002] The tire vulcanization device is a device that puts a raw rubber tire (green tire) preformed into a shape similar to the finished product into a metal mold, and applies heat and pressure to finally form the shape of the finished tire. [0003] In this kind of tire vulcanization device, especially in the tire vulcanization device for manufacturing large tires with an outer diameter of more than 1.5m, in order to facilitate the feeding of the green tire before vulcanization and the delivery of the finished tire after vulcanization, a method of using the bottom tire is adopted. The structure of the slide-back method in which the upper die moves to the retracted position after the die is separated and raised. [0004] Figure 5 and Image 6 It shows the conventional structure of the tire vulcanizing device adopting the slide back stru...
