金属与树脂的复合体及其制造方法
摘要：
本发明提供金属与树脂的复合体及其制造方法，是将金属形状物与热塑性树脂形状物利用注射成形一体化地接合(注射接合)的复合体，实现了热塑性树脂形状物相对于金属形状物的垂直精度的提高。金属与树脂的复合体(40)由金属形状物(20)、利用注射成形与该金属形状物(20)的一方的面一体化接合的热塑性树脂形状物构成。热塑性树脂形状物具备底座(42)、从该底座(42)上竖立设置的凸台部(41)。设有横浇道(43)，其经由2个以上的直浇口与底座(42)连通，将从浇口(45)注射的熔融了的热塑性树脂流入凸台部(41)，从所述浇口(47)向凸台部(41)的相面对的部位大致均等地流入、填充从浇口(45)注射的所述热塑性树脂。由此就可以将凸台部(41)与金属形状物(20)垂直地注射接合。
摘要（英）：

The invention provides a complex of metal and resin and a manufacturing method thereof. The complex is formed by integrally joining a metal object and a thermoplastic resin object through injection (injection join), realizing improving vertical precision of the thermoplastic resin object with respect to the metal object. The complex (40) of metal and resin is formed by integrally joining a face of the metal object (20) and thermoplastic resin object through injection moulding. The thermoplastic resin object has a pedestal (42) and a lug boss part (41) vertically provided on the pedestal (42).A transverse pouring channel (43) is provided and is communicated with the pedestal (42) through over two vertical poring ports. The molten thermoplastic resin injected from the pouring port (45) flows into the lug boss part (41). The thermoplastic resin injected from the pouring port (45) is uniformly filled and flows to the part facing to lug boss part (41) from the pouring port (47). Therefore, the lug boss part (41) and the metal object (20) can be vertically joined by injection.
