Abstract
To improve the problem of uneven wall thickness in the blow molding process of plastic oil drums,Ployflow software was used to perform numerical simulation on a specific model of plastic oil drum.An orthogonal experiment was designed to study the effects of blow time,blow pressure,and mold movement speed on the forming of the plastic oil drum.The variance of the wall thickness of the product was used as the measurement standard to achieve the goal of optimizing the overall wall thickness uniformity of the blow molding.The results showed that the blow pressure had a significant impact on the blow molding quality of the plastic oil drum.Under the conditions of a blow time of 6 s,blow pressure of 0.2 MPa,and mold movement speed of 0.6m/s,the wall thickness distribution of the plastic oil drum was relatively uniform.This study provides reference for the actual production of plastic oil drums.关键词
