INSULATING MATERIAL FOR SLOT COIL OF ROTATING MACHINE AND MOLDING METHOD THEREFOR

A thermoplastic synthetic resin, which has flowed into tab-shaped flanges 16, 16 from gates 173, 173 on both sides, collides with a facing wall 161 of each tab-shaped flange 16, thereby changing direction by 90 degrees and reducing the inflow speed, and fills the tab-shaped flanges 16, 16 and long-s...

Zusammenfassung:A thermoplastic synthetic resin, which has flowed into tab-shaped flanges 16, 16 from gates 173, 173 on both sides, collides with a facing wall 161 of each tab-shaped flange 16, thereby changing direction by 90 degrees and reducing the inflow speed, and fills the tab-shaped flanges 16, 16 and long-sided flanges 15, 15. Subsequently, the thermoplastic synthetic resin flows into thin outer peripheral walls 131, 132 and partition walls 133 at an optimal inflow speed; therefore, the flow of the thermoplastic synthetic resin improves, thus making it possible to create a smooth molded article with an accurate shape. The tab-shaped flanges 16, 16 and the long-sided flanges 15, 15 function as runners, and the thermoplastic synthetic resin smoothly flows into the thin outer peripheral walls 131, 132 and the partition walls 133.
