<P>PROBLEM TO BE SOLVED: To solve the problem that, when a raw material resin for injection molding stored inside a hopper is dried, since an independent drier separate from an injection molding machine is used heretofore, the whole equipment is enlarged, and further, energy efficiency is bad. <P>SOLUTION: The injection machine comprising a heat recovery means 15 having a heat exchange part 51 for recovering heat generated in an injection molding machine and a hopper 40 storing a raw material resin 11 and feeding the same to an injection cylinder part 13 in the injection molding machine contains: a hot blast duct 52 in which one end side is fitted with the heat exchange part 51 and the other end is communicated with the inside of the hopper 40; an exhaust fan 53 for introducing the heat recovered in the heat exchange part 51 from the hot blast duct 52 into the hopper 40 as hot wind; and a heat recovery means 15 communicated with the exhaust port 56 formed at the hopper 40, and the exhaust fan 53 is assembled into the exhaust duct 54. <P>COPYRIGHT: (C)2009,JPO&INPIT |
