Title: Processing method for welder of thermoplastic synthetic resin sheet
Inventor: HARADA KUNIHIKO
IPC: B29C65/04
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a protrusion of the surface of a sheet from generating a sink, by performing welder processing in a nonpressing recessed part in a design surface by a mold electrode provided with a vent path. CONSTITUTION:Fine two vent holes (vent paths) 30, 30 for ventilation of inner air of the inside of a nonpressing recessed part 122 are formed by penetrating through the top of a top force electrode 12 and molding surfaces of the nonpressing recessed part 122, in the nonpressing recessed part 122 of a design surface of the top force electrode 12. When a sheet S is pressed by the top and bottom force electrodes 12, 11, a part of the sheet S is pressed into the nonpressing recessed part 122. At this time, though a part of the sheet S becomes a softened state by heat transferred from the top force electrode 12, since the inner air is ventilated outside through the vent holes 30, 30 each, a part of the sheet S is crushed to a deformation by expansion pressure of compressed inner air, through which generation of what is called a sink can be prevented.
