发明名称 INJECTION MOLDING DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To obtain uniform transfer by preventing a filler from floating up to the surface side of a molded product under the state that the filler such as glass is contained in synthetic resin. Ž<P>SOLUTION: Under the condition that, before the pouring of the synthetic resin in a cavity S, the temperature on the cavity forming surface side of a fixed mold 6 is raised by feeding hot vapor into the heating medium passage 35 of the fixed mold 6 than the softening point temperature of the synthetic rein or higher, by providing a difference 40 in level on a parting surface, the heating medium passage 35 nearest to the parting surface can be brought to the higher surface 26A and 6A of the parting surface as nearer as possible through its provision near to the lower end of the cavity S, resulting in also raining the temperature of the parting surface near the cavity S equal to the temperature of the central part on the cavity forming the surface side of the fixed mold 6 or the like. In addition, as the heat heated on the cavity forming surface side of the fixed mold 6 is hindered by an open air flow passage 38 from being transmitted to a movable mold 26 and from being taken away, a sufficient temperature rise is also attained in the parting surface.
