2 二次射出成形部
3 合成樹脂射出成形品
Claims (1)
- 硬質合成樹脂の一次射出成形により成形した一次射出成形部の外面の一部に、軟質合成樹脂の二次射出成形により成形した二次射出成形部を重複一体化した合成樹脂射出成形品において、一次射出成形部の表面側の外面の一部の二次射出成形部の背面の重複部が重複する部位の全部又は一部を、表面側の外面の重複しない部位よりも背面側に凹ませ、一次射出成形部の二次射出成形部の重複部が重複する部位及びこの重複する部位に隣接する部位の背面側の外面を、一次射出成形部の他の部位の背面側の外面より背方に膨出させ、二次射出成形部の重複部の肉厚を各部においてほぼ同じとすると共に、この重複部の端縁部が、重複部の他の部位に対して端ほど背方となるように傾斜した表面側の傾斜面及び同じ傾斜となった背面側の傾斜面を備えた傾斜した端縁部となり、一次射出成形部の外面の一部に重複した二次射出成形部の重複部の背面部の全部又は一部を一次射出成形部の外面の上記凹みに埋設し、二次射出成形部の重複部の傾斜した端縁部の背面の傾斜した部分の一次射出成形部への埋設深さを他の部位の埋設深さよりも深くすると共に、二次射出成形部の一次射出成形部への重複部の傾斜した端縁部の表面の傾斜した部分を重複部の他の部位に比べて一次射出成形部の表面側の外面からの突出高さを低くして成ることを特徴とする合成樹脂射出成形品。
