Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold changing device for a tire vulcanizer.

The tire vulcanizing machine already proposed by the applicant is explained with reference to Figs. 1 to 6. (1) is the base of the tire vulcanizing machine; A register ring (2) is attached, and a lower hot plate (3) is fitted thereto, and a lower mold (4) is installed by tightening bolts (5) to the lower hot plate (3). In addition, the upper mold (6), which forms the mold sound with the lower mold (4), is connected to a bolster (7) provided in the vulcanizer mold opening/closing mechanism (not shown) via the upper hot plate (8). installed. Note that (9) is a bolt for fixing the upper mold (6) and the upper hot plate (8). Also, the above is one step (1
) is equipped with a so-called swing cylinder (a type of swing cylinder in which the cylinder rod is expandable and retractable, and the rod can rotate approximately 90 degrees when contracted).
The upper surface of the flange fitting (10α) at the rond end engages with the lower surface of the pot (3C) on the outer periphery of the lower hot plate (3), so that the lower hot plate (3) is raised and lowered by the raising and lowering of the rod of the cylinder. Also, the bottom surface of the same clamp fitting (10α) is the lower heating plate (3).
It is designed to detachably engage with the upper surface of the collar (3d) on the outer periphery of the holder. Further, the connection between the bolster (force) and the upper hot plate (8) is achieved by providing the bolster (7) with something similar to the cylinder described above, or by simply using a pole-Y. In addition, the upper and lower heat plates +3) (8) are each equipped with steam supply and exhaust pipes (3α
) (3bX8α) (8h), and quick joint (11α) (IIh) (12α) (12
b) are removably connected to the holster (7) and the piping (13a) (13b) (14'Z) (14b) on the X' (1) side. In addition, the mold exchange trolley (A) is movable with wheels, and the frame of the trolley (fA) has a group of rotating rollers (le) and a pair of arms (1 and 1) that can be moved in and out. The arm (Lη) is guided by a guide roller 081 and is movable between the same roller group (1θ).

Also, on the upper surface of the same arm αη, there are many rotating ball bearings a
1 is attached to the lower surface of the arm αη, and a group of rollers (
b) is installed. In addition, the vulcanizer body x-s(1)
A centering lock (1a) is fixed to the centering lock (1a), and the wedge (3g) of the lower hot plate (3) is fitted to this to center the glock (1a) on the vulcanizer main body base (1). Furthermore, there is a heat insulating plate between the lower heating plate (3) and the lower mold (4), but the illustration Z is omitted.

Next, the operation of the mold changing device of the tire vulcanizer will be explained. When replacing the mold, the upper and lower molds (41(6)'!rpol)
(Attach the upper and lower heat plates (3 bar 8) with 51 (9),
) and (3), and (6) and (8) respectively, install the piping (3α) (3/') (8α) (
8h) to the upper and lower hot plates +3) (8),
Preheat the hot plate and mold. Thereafter, the hot plate and mold assembly is placed on the trolley (Al) and transported to the front of the vulcanizer. At this time, arm a of the trolley (A)
It is stored in the section (17 (Z)) between the upper roller group (16). The arm α7) is then stopped at a fixed position by a known method such as a centering pin (not shown).Then, the arm α7) is pushed out toward the vulcanizer side manually or by a cylinder mechanism.Then, by the rope force , the hot plate and mold assembly are transferred together with the arm Cη onto the vulcanizer main body base (1), and the centering ring (1eL) of the vulcanizer main body base (1) and the wedge part of the lower hot plate (3) (
3C), the same hot plate and mold assembly is the base (1)
At this time, even if the stop position of the trolley (A) is inaccurate, the guide function of the pole bearing pupil, block (1α) and (rust part) will keep the hot plate and mold The assembly is correctly positioned on the base (1) by freely moving the upper part of the arm αη in the front-back and left-right directions.Then, extend the cylinder (190 rod) upward and attach the clamp fitting as shown in the right-hand view of Figure 6. After supporting the hot plate and mold assembly χ via Yotsuba (3C)'r on the upper surface of (10α),
Move the arm α7) backward toward the N side. At this point, the rod of the cylinder (ll) can be retracted. Then, the hot plate and mold assembly will be moved to the center of the lower hot plate (3) or the lower mold (4). Place the hole on the base (1) while being guided by the register ring (2). At this time, the cylinder (10
) is rotated approximately 90° near the retraction limit, and the clamp fitting (10α) is attached to the lower heating plate (3) as shown in the left half of Figure 3.
Firmly grasp the lower brim (γ) of the Next, quick joint (1
1α) (Ilb) (12α) (, 12b), each hot plate pipe χ is connected to complete the work.

In the mold changing device, the centering block (1α) on the base (1) side of the vulcanizer body and the wedge part (3) on the lower hot plate (or dummy plate) (3) side separate the hot plate and mold assembly. In order to perform positioning (centering), all vulcanizers are equipped with this centering Glock (1α) and a specially shaped lower heating plate (or dummy brake).
(31), and there was a problem in that a large amount of modification costs would be required when automating mold replacement in an existing tire vulcanizer.

The present invention addresses the above-mentioned problems, and includes a mold exchange trolley that runs on a rail and stops when it directly faces a tire vulcanizer, and a mold that is mounted on the trolley so that it can be raised and lowered. a lifting drive device for raising and lowering the centering member; an arm for carrying in and out of molds that is provided on the trolley on the side of the centering member so as to be able to move forward and backward; a forward and backward drive device for

The mold changing device for the tire vulcanizer of the present invention is constructed as described above, and the mold can be reliably centered on the mold changing cart, and a special centering member is installed on the vulcanizer main body side. There's no need. Furthermore, since centering is performed on the inner circumferential surface of the mold, there is no need to adjust the centering member even for molds with different outer diameters. Alternatively, it is sufficient to simply replace the centering member with a centering member of a different diameter, which has the effect of making it extremely easy to deal with molds having different outer diameters.

The present invention has been described above with reference to embodiments (1), but of course the present invention is not limited to such embodiments (and various modifications to the design may be made without departing from the spirit of the present invention). It is something.
