| 摘要 |
The present invention relates to a balance molding apparatus and, more specifically, to a balance molding apparatus which enables a continuous molding operation. To this end, combined injection and compression molding for a mixed ingredient of iron powder and a thermoplastic resin is carried out step by step, thereby increasing the compression rate of the balance. Supplied with the mixed ingredients from a ingredient mixer, the volume of an ingredient extruder which transports the ingredients to a mold is formed in a bigger size than the ingredient mixer. By forming, at a side of an inlet, an ingredient storing chamber which has a larger volume than a main body of the ingredient extruder, the mixed ingredients supplied from the ingredient mixer can be sufficiently accommodated while molding, compressing, and cooling a product in the injection mold and the extruder. In addition, the ingredient mixer can operate continuously without interruption. |
