摘要： The present invention relates to an injection mold device having a shear flow making part. The device comprises an injection mold provided with a cavity in which molten resin mixed with predetermined pigments is filled, a shearing force making part installed in the injection mold, some portion thereof being exposed to the cavity to be in contact with the molten resin injected into the cavity and driven by external power to cause the molten resin in contact with the surface thereof to generate shear flow by a viscosity thereby adjusting locations of the pigments within the molten resin; and a driving part for driving the shearing force making part.The injection mold device according to the present invention is capable of solving a problem due to poor orientation and lack of content of the pigments at a vicinity of the weldline thereby manufacturing a high quality product by generating a viscous flow in the molten resin located at a weldline generation area in an inside of an injection mold and thus adjusting location of the pigments mixed in the molten resin in the corresponding area.

The polymer resin composition includes: a polymer resin; 0.01-10.0 parts by weight of flaky pigment particles having an inverse aspect ratio of 0.01-0.1 based on 100 parts by weight of the polymer resin; and 0.01-10.0 parts by weight of polyhedral pigment particles having an inverse aspect ratio of 0.300-0.999 based on 100 parts by weight of the polymer resin. Using the polymer resin composition, a polymer resin molded product having excellent appearance, i.e., having a uniform color even in resin flow lines or resin weld lines, and in which there is no degradation in the physical properties of the polymer resin contained therein can be manufactured at a low cost.
