摘要： An injection-molding apparatus comprising:

an injection machine (2),
a mold unit (1) connected to said injection machine and comprising separable molds (11,12), which constitutes therein a cavity for forming a molded product, and
a holding means (3) disposed adjacent to said mold unit for removing said molded product from said mold unit, comprising a plural of chucks (35) adapted to advance into and retreat from a region defined between the opened molds of the mold unit,
said molded product being subjected to a primary cooling in the cavity of said mold unit and then subjected to a secondary cooling after removed from the mold unit, and
the ratio of the number of said chuck to the number of said cavity being set to a value not less than a ratio of an operation time of each chuck to an operation time of said mold unit; and
a method for injection-molding a molding material comprising a thermoplastic resin and an inorganic filler using the apparatus.

The injection-molding apparatus and method according to the present invention are useful for the production of such articles required to have a high dimensional accuracy, for example electronic parts such as a magnet roll or the like.
