INTEGRAL MOLDING METHOD FOR CROSS FLOW FAN

INTEGRAL MOLDING METHOD FOR CROSS FLOW FAN

PURPOSE:To effect integral molding of a cross flow fan by drawing a gap forming mold making contact with the surface side of a single sheet and a gap forming mold making contact with the back side thereof with a time lag and drawing a central mold in the direction of length. CONSTITUTION:When a gap...

description PURPOSE:To effect integral molding of a cross flow fan by drawing a gap forming mold making contact with the surface side of a single sheet and a gap forming mold making contact with the back side thereof with a time lag and drawing a central mold in the direction of length. CONSTITUTION:When a gap forming mold 3 located in a gap 2 between sheets 1 is drawn in a radial outward direction P, a gap forming mold 3a group making contact with the surface side of the single sheet 1 is arranged such that the mold group is simultaneously drawn in a relation between a pin 7 and a guide groove 8 through rotation of a cam board 6. A gap forming mold 3b group making contact with the back side thereof is arranged in a similar manner described above. The shape of the groove 8 of the mold 3b group is formed such that a portion extending to the middle is formed in the shape of an concentric arc of circle 8' so that the mould 3b group is drawn after drawing of the mould 3a group. Thus, since drawing is effected with a time leg, when the mould 3a group is first drawn, it is smoothly drawn in a state to be supported to the mould 3b group, and when the mould 3b group is drawn, since the one side of the sheet 1 is already brought into a free state, the mould group is smoothly drawn.
