Abstract

The invention discloses an injection mould with a pushing needle for pushing out. The injection mould includes a bottom plate, a back mould plate and a surface plate. The surface plate is provided with a front mould plate. The front mould plate and the back mould plate are movably connected to each other through a guide column. A back mould insert is arranged in the back mould plate and a front mould insert is arranged in the front mould plate. A flow pass is disposed between the front mould insert and the back mould insert. The bottom plate is provided with a pushing needle bottom plate. The pushing needle bottom plate is provided with the pushing needle, a first water opening pushing needle, a second water opening pushing needle and a third water opening pushing needle, wherein heads of the pushing needle, the first water opening pushing needle, the second water opening pushing needle and the third water opening pushing needle are disposed in the flow pass. The head of the second water opening pushing needle is fan-shaped and the heads of the first water opening pushing needle and the third water opening pushing needle are ball-shaped. The injection mould is simple in structure and is convenient to use. A material is convenient to push out. The injection mould is large in material-pushing strength and a plastic workpiece can be pushed out more conveniently during a demoulding process.
