Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a urethane foam that can be arranged in large numbers in parallel on the same plane to form a heat insulating wall of an LNG ship, a heat insulating wall of a gas holder, or a heat insulating wall of a refrigerated warehouse. A facility for molding and manufacturing panels made of foam material, which injects foam material into the panel molding form while circulating the panel molding form along a fixed path in a closed loop.
The present invention relates to so-called continuous foam molded panel manufacturing equipment that continuously manufactures panels by sequentially performing curing and taking out molded panels in an assembly line manner.

An object of the present invention is to extremely easily, quickly and reliably switch the molding formwork between the formwork completed position and the mold release position from which the molded panel can be taken out after curing, without using any special equipment. The object of the present invention is to make it possible to manufacture panels by circulating the molding frame in a truly rational and efficient manner.

In other words, in conventional continuous production equipment for foam molded panels of this type, the molding form is circulated and moved by an endless rotating body such as a trolley conveyor, but when pouring foam into the molding form and forming the molded panel from the molding form. The mold for molding was taken out from the endless rotating body at the time of removal.

Therefore, especially when the molding form is large and heavy, a special device is required to take out and attach the molding form to the endless rotating body, which is expensive in terms of equipment. Poor workability.

In addition, conventional equipment connects the front and back opposed formworks and the circumferential formwork that make up the molding formwork to each other via bolts and nuts. By separating the molding formwork, the molding formwork is placed in a releasing position. Therefore, it takes a lot of effort and effort to change the position of the molding formwork, and the molding formwork is large and heavy. In some cases, special attitude switching devices are required.

In this way, conventional foam molded panel continuous manufacturing equipment requires a large number of large auxiliary equipment and is expensive, and the work of pouring foam into the molding form and taking out the molded panel is complicated and troublesome. Therefore, it was not possible to truly improve the efficiency of panel manufacturing by circulating the molding form.

In view of these points, the present invention fixes and supports one of the front and back opposed molds constituting the molding mold with respect to the endless rotating body, and supports the other mold and the peripheral side. The formwork is integrally supported with respect to the fixed formwork so as to be swingable and switchable between a formwork completed position and a mold release position, and this movable formwork is connected to the fixed formwork via a worm gear mechanism. A continuous manufacturing facility for foam molded panels was constructed by equipping the formwork with a formwork operating device that selectively swings the frame between the two positions described above.

Therefore, according to the configuration of the present invention, with the fixed formwork being fixedly supported by the endless rotating body, by swinging the other formworks and the peripheral formwork with respect to the fixed formwork, it is possible to Since the formwork can be switched between the formwork completion position and the mold release position, foaming injection work and molded panel removal work can be performed while the molding formwork is fixedly supported by the endless rotating body.

Moreover, since the mold itself is provided with a device for changing the posture, the posture of the mold can be changed simply and quickly by simply operating the device.

Furthermore, since the posture switching device is composed of a worm gear mechanism, the formwork posture can be switched with a very light operation, and the formwork posture after the change can be fixed by the worm gear mechanism. No special locking mechanism is required.

As described above, the present invention is capable of keeping the molding form always supported by the endless rotating body, and that the posture of the molding form can be changed extremely quickly, easily, and reliably without using any special equipment. As a result, it has become possible to provide a rational continuous foam molding panel manufacturing facility that continuously manufactures panels by circulating the molding frame.
