Description

Plastic part forming rear die with single-ended and different-direction chute

Technical Field

The utility model relates to an injection mold, in particular to a plastic part molding rear mold with a single-ended anisotropic chute.

Background

Plastics are increasingly used in life due to their various excellent physical and chemical properties. Thermoplastics are convenient to mold and are therefore typically injection molded into the desired appearance and structural parts. When a chute with an opening direction inconsistent with the direction of the rest surface is formed at one end of the plastic part, the chute is usually demolded by adopting a strong demolding mode, and in order to facilitate demolding, the chute cannot be too deep or the inclination direction cannot deviate too much. When the deflection angle of the chute is larger and the depth of the chute is deeper, the forming sliding blocks are required to be arranged independently to form the chute, but when the size of the plastic part is smaller, a plurality of sliding blocks are used at the same end, and the space is limited, so that the forming sliding blocks cannot be realized.
