Heat Allowed resin - method of manufacturing a belt to be successively uneven molding the door on a metal plate rotating belt and it by resin - shot molding apparatus and cooling method and apparatus for producing a molded belt.

摘要

[Challenge] In one set of press mold, thermoplastic resin of softening state - an uneven pattern shape to produce an uneven metal plate belt to continuous vacuum forming Doo, further melt resin - bets does not adhere to the metal plate belt As such, a metal plate back resin - to provide a technique for cooling during molding bets. A in opposing molding sides the same length, in the case of the press upper and lower molds the same irregularities are aligned, by fitting the shape terminal is molded to the metal plate 1 to the press die opposite the terminal, vertical the following press molding, continue to the next both. Or in the case of the type that forms the one or more straight lines and curves, with the pattern on the metal plate with the concavo-convex pattern of the shaped edge and the inner surface by press molding, the surface is connected to the belt so that the surface. The belt by opening a large number of small holes 17, the metal belt 19 is rotated, the soft, hot melt resin of the hard - transferring an uneven pattern by vacuum forming method and. In cooling the backside of the metal belt with a cooling belt 41 which moves in contact with the same speed. [Selection Figure] Figure 1
