(57) [Summary] [Objective] The present invention is a mold for preheating a mold to a predetermined temperature by a mold heating device separate from the tire vulcanizer before setting the tire vulcanizer. A heating device is provided. An upper heating plate and a heat shield attached to the lower surface of a beam that can be moved up and down, a carriage movable between a heating position below the upper heating plate and a standby position lateral to the heating position, and A heating device for a tire vulcanizing mold, comprising: a lower heating plate attached to an upper surface of a trolley, configured to heat the tire vulcanizing mold between the upper heating plate and the lower heating plate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for heating a tire vulcanizing mold before incorporating it into a tire vulcanizing device.

[0002]

[Prior Art]

 A tire vulcanizing mold is usually heated in a tire vulcanizing apparatus until a predetermined temperature is reached.

[0003]

[Problems to be solved by the device]

 When the tire vulcanization mold is heated by the tire vulcanizer, it usually takes 3 to 4 hours. During this time, the tire vulcanizer cannot produce tires, and the production efficiency of the tire vulcanizer is high. Is reduced. An object of the present invention is to provide a mold heating device for heating a mold to a predetermined temperature by a heating device separate from the tire vulcanizer before setting the mold on the tire vulcanizer. To do.

[0004]

[Means for Solving the Problems]

 By installing a mold heating device separate from the tire vulcanizer and heating the mold to a predetermined temperature in advance, the production efficiency of the tire vulcanizer is improved. Since a tire vulcanizer can usually be fitted with two molds, a heating device for such a tire vulcanizer should have a structure capable of simultaneously heating two molds.

[0005]

[Action]

 At the standby position, place the tire vulcanization mold on the lower heating plate of the truck and move the truck to the heating position. The upper heating plate is lowered onto the tire vulcanizing mold, and at the same time, the periphery of the tire vulcanizing mold is surrounded by a heat shield, and the upper and lower heating plates heat the mold. The heated mold is moved to the standby position again and set in the tire vulcanizer by a crane or the like.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. In the figure, 1 is a frame, 2 is a beam, 3 is a lifting cylinder, 4 is an upper heating plate, 5 is a guide device, 6 is a beat shield, 7 is a tire vulcanizing mold, 8 is a trolley, and 9 is a lower heating plate. Reference numeral 10 is a wheel, 11 is a rail, 12 is a cylinder for moving a carriage, and two upper heating plates 4 of the same type are fixed to a beam 2. The beam 2 can be moved up and down by using a frame 1 as a guide. The lifting cylinder 3 and the guide device 5 mounted on the upper part realize the lifting operation. The heat shield 6 is prepared to reduce heat dissipation when the mold 7 is heated, and is attached to the beam 2. Two lower heating plates 9 of the same type are fixed to a dolly 8, and the dolly can be moved forward or backward by rotating wheels 10 using a rail 11 as a guide. This operation is realized by the carriage moving cylinder 12. The upper heating plate 4 and the lower heating plate 9 ensure a predetermined temperature and capacity by introducing steam having a predetermined pressure into the pipes and hoses. A timer for measuring these heating times and a temperature recorder (not shown) for monitoring the time course of temperature are also provided.

Next, the operation of this device will be described. The mold 7 to be heated is installed on the lower heating plate 9 from above at the stand-by position of the truck by using a crane or a forklift. In order to avoid interference with the mold 7, the upper heating plate 4 moves to the raised position. The dolly 8 moves to the heating position by the operation of the dolly moving cylinder 12. At the heating position, the upper heating plate 4, the heat shield 6, the mold 7, and the lower heating plate 9 are located on the same center.

The upper heating plate 4 and the heat shield 6 descend to a lower position where the lower surface of the upper heating plate 4 contacts the upper surface of the mold 7, and then stop. At this position, set the timer for the required time and start the mold heating. Further, at this position, the heat generated from the upper heating plate 4 and the lower heating plate 9 is effectively added to the mold 7, so that the heat shield 6 covers the mold 7 to reduce the amount of heat dissipated. The mold 7 which has been heated is taken out of this apparatus by the reverse operation to the above.

By using this apparatus as described above, it has become possible to improve the production efficiency of the tire vulcanizer by about 5% as described below. (Assuming that the mold is changed once every 3 days) 3 hours / 3 days × 24 hours × 0.9 ≒ 0.05

[0010]

[Effect of the device]

 A heating device for a tire vulcanizing mold according to the present invention includes an upper heating plate and a heat shield mounted on the lower surface of a beam that can be raised and lowered, a heating position below the upper heating plate, and a standby position beside the heating position. And a lower heating plate attached to the upper surface of the trolley, which is configured to heat the tire vulcanizing mold between the upper heating plate and the lower heating plate. By doing so, it has the following effects.

Since it is not necessary to heat the mold to the required temperature in the tire vulcanizer, the time required for heating the mold (usually 3 or 4 hours) is unnecessary, and the productivity of the tire vulcanizer is improved.
