Abstract
This article proposes a set of counter-pressure injection foaming molding process and mold design optimization solutions to solve the manufacturing problems of automobile instrument panel injection molded parts with complex structures and high performance requirements.Through the pre-setting mesh cloth by the manipulator and the staged back pressure injection molding foaming process,the airbag area is injected first under the condition of 1 mm mold gap,and the mechanical properties of the airbag area of the product are improved by the mesh cloth reinforcement effect and pressure gradient control.In view of the control requirements of the non-foaming area,a pneumatic ejector and cylinder drive spring block composite system is developed,and anti-foaming control is achieved through dynamic pressure compensation.According to the characteristics of the mold structure,different water channels are designed on both sides of the mold,and 3D printing water channels and beryllium copper inserts are designed in the airbag area to ensure the consistency of the overall cooling of the injection molded parts.Through the above mold process optimization and mold structure design,high-quality and high-performance molding of complex parts of automobile instrument panels is achieved.关键词
