Technical Field

The utility model relates to a punching press and press-cutting machine equipment field especially relate to a die cutting machine suitable for injection molding.

Background

Injection molding, also known as injection molding, is a process in which a plastic material that is completely melted is stirred by a screw at a certain temperature, injected into a mold cavity at high pressure, and cooled to solidify to obtain a molded article. The method is suitable for mass production of parts with complex shapes. The workpiece manufactured by injection molding is not a final product after demolding, so that an injection molding part needs to be processed, the traditional method is that unnecessary injection molding waste is manually cut off, and a needed injection molding product is left, although the injection molding improves the production efficiency, the later manual processing occupies a large amount of time, the whole production efficiency is reduced, and the size and the shape of the manually processed product are often not accurate enough, so that the defective rate is increased.

The utility model provides a die cutter suitable for injection molding, this die cutter lean on stamping equipment and die-cut mould to exert external force to the injection molding and cut to obtain the injection molding of required shape and size. The operation personnel use this die cutter can effectively improve production efficiency, and this die cutter is particularly useful for annular injection molding.

Injection molding preparation's injection molding, its shape is decided by injection mold, injects into injection mold with fused raw materials through the mouth of moulding plastics, and unnecessary raw materials also can the cooling forming between mouth of moulding plastics and the injection molding, the utility model discloses in be called "unnecessary portion" with this part. In the injection molding process of ring-shaped injection-molded parts, the excess part is often connected at the inner hole of the ring-shaped injection-molded part.
