However, it is difficult to seal the fluid sent to the heating pressurizing chamber and the cooling pressurizing chamber in the above-described structure of the continuous press device by the fluid pressurizing system, and this fluid is heated at a high pressure. When it is sent to the pressurizing chamber and the cooling pressurizing chamber, fluid leaks from the seal portion, which is very dangerous. For this reason, the heating press surface plate frame and the cooling press surface plate frame must be strongly pressed against the conveyor belt, and a frictional force is generated between the end surface of the press platen frame and the corresponding conveyor belt surface. Also,
In the configuration of the continuous press device using the pressure plate pressing method described above, the material to be molded is pressed by the pair of upper and lower press platens via the transfer belt formed of metal such as stainless steel, and is transferred to the upper and lower press platens. Since the belt is in direct contact with the belt, when the conveyor belt is driven by a driving means such as a motor to convey the material to be molded, friction is generated between the upper and lower press surface plates and the conveyor belt. In order to drive the conveyor belt against these frictional forces, it is necessary to increase the output of the driving means such as a motor that drives the conveyor belt, but this is uneconomical because the energy conversion efficiency deteriorates. Further, as described above, as the output of the driving means such as the motor is increased, the output of the transport belt formed thinly cannot be received and the transport belt is damaged or damaged.
Since the conveyance may be interrupted, it is necessary to make the conveyor belt thicker, but it is preferable that it be thin in order to smoothly follow the conveyor belt. Also, increasing the thickness causes poor heat conduction characteristics. And the energy loss increases,
It may adversely affect the press.

The present invention has been made in view of the above circumstances, and an object of the present invention is to convey a molding belt while conveying the molding material while press-molding the molding material via the conveyance belt. By suppressing the friction generated with the press surface plate, the thinly formed conveyor belt is pressed to improve the heat conduction characteristics without being damaged or damaged by the driving means such as a motor with a small output. It is an object of the present invention to provide a continuous press device that can be conveyed while being conveyed.
