双色成形法和双色成形用模具及双色成形品
Abstract:
本发明提供一种双色成形法、双色成形用模具、双色成形品，在双色成形时，可防止第一树脂部的树脂收缩、树脂变形为要因的外观品质的降低。一种双色成形法，包含由通用模具(K20)和第一次模具(K21)成形第一树脂部31的工序、由通用模具(K20)和第二次模具(K22)与第一树脂部31一体成形第二树脂部(32)的工序，其中，在第二树脂部(32)成形时，利用第二次模具(K22)所具备的保持部(4)保持第一树脂部(31)形状。即使第一树脂部(31)在成形后变形，由于利用保持部(4)保持第一树脂部(31)形状，所以也可以防止第一树脂部(31)形状变形为要因的双色成形品外观品质的降低。
Abstract(English):

Provided are a two-color molding method, a two-color molding die, and a two-color molded article capable of suppressing deterioration of the appearance quality which is caused by resin shrinkage or resin deformation in a first resin portion in the two-color molding. The method includes molding a first resin portion (31) by a common die (K20) and a primary die (K21); and molding a second resin portion (32) by the common die (K20) and a secondary die (K22) integrally with the first resin portion (31), in which a shape of the first resin portion (31) is maintained by a holder provided in the secondary die (K22) in the molding of the second resin portion (32). Even when the molded first resin portion (31) is deformed, the shape of the first resin portion (31) is maintained by the holder (4). Accordingly, deterioration of an appearance quality of the two-color molded article, which is caused by a shape deformation of the first resin portion, is suppressed.
