This invention belongs to the field of
polyurethane foam molding and curing technology, specifically referring to a high
flame-retardant
polyurethane foam foaming, molding, and curing equipment and its usage method. It includes a curing frame, an
internal heating curing mechanism, and a bottom-measuring localized cooling mechanism. The
internal heating curing mechanism is mounted on the curing frame, and the bottom-measuring localized cooling mechanism is mounted on the
internal heating curing mechanism. The internal heating curing mechanism includes a molding component, a curing component, an
auxiliary heating component, and a closing component. The molding component is located on the inner side wall of the curing frame, the curing component is located on the bottom wall of the curing frame, the
auxiliary heating component is located on the upper wall of the molding component, and the closing component is located on the upper wall of the curing frame. The bottom-measuring localized cooling mechanism includes a temperature measuring component, a reversing component, a surface-applying component, and a cooling component. This invention provides a high
flame-retardant
polyurethane foam foaming, molding, and curing equipment and its usage method that enables the
internal temperature of the foam to be higher than the surface temperature during the curing process, preventing the foam from becoming soft and sticky due to insufficient reaction.
