| description | To improve precision of adding fillers and manufacture moldings with higher performance.SOLUTION: A molding is manufactured by using an injection molding device which includes: a cylinder 11 that has a supply port 13h positioned on an upstream to be supplied with a resin material, and a supply port 15h positioned on a downstream of the supply port 13h to be supplied with a filler F; a screw S arranged in the cylinder; a drive part for controlling rotation, forward and retraction movements of the screw S; and an elevator mechanism for elevating/lowering a stick ST which is a rod-like jig at the supply port 15h. By providing a bridge prevention device for elevating/lowering the stick ST, bridging of the filler F (formation of aggregates of the filler F) to be added in a vicinity of the supply port 15h can be prevented, precision of adding the filler F to a molten resin can be improved, and also, the filler F can be more evenly dispersed in the molten resin. As a result, properties such as mechanical strength of the molding to be formed are improved.SELECTED DRAWING: Figure 1
【課題】フィラーの添加精度を向上させ、より性能の高い成形体を製造する。【解決手段】上流に位置し樹脂材料が供給される供給口１３ｈと、これより下流に位置しフィラーＦが供給される供給口１５ｈとを有するシリンダ１１と、その内に配備されたスクリュＳと、このスクリュＳの回転、前進および後退を制御する駆動部と、供給口１５ｈにおいて棒状のジグであるスティックＳＴを昇降させる昇降機構と、を有する、射出成形装置を用いて成形体を製造する。スティックＳＴを昇降させるブリッジ防止装置を設けることにより、供給口１５ｈの近傍において添加するフィラーＦのブリッジ（フィラーＦの塊の生成）を防止することができ、溶融樹脂へのフィラーＦの添加精度を向上させることができ、また、溶融樹脂へフィラーＦをより均一に分散させることができる。その結果、形成される成形体の機械的強度などの特性が向上する。【選択図】図１ |
