摘要:利用 Moldflow 对塑料排水泵过滤网的注塑成型过程进行仿真 ,通过对其结构分析制定了合理的浇口位置和冷却水路。 利用三因素三水平正交试验,研究了熔体温度(A) 、充填压力(B)和开模时间(C)对于塑件翘曲变形的影响,得出较优的工艺参数组合为A1B3C3,即熔体温度 220 ℃,充填压力 80%,开模时间 6 s,此时塑件的最大翘曲变形量1 3 3为 0.632 8 mm,与优化前相比降低了 10.37%。最后依据 Moldflow 的分析结果 ,利用 UG 软件对注塑模具的结构进行了设计,根据塑件卡扣的结构特点,型腔采用整体式结构 ,型芯设计为组合式( 主型芯+ 滑块)结构,并采用三组“ 斜导柱+ 滑块”式侧向抽芯机构解决脱模问题。为实现顺序脱模,借助尼龙塞以增加定模板与动模板之间的开模阻力 ,设计了内置式“小拉杆+拉杆套”结构的定距分型机构;考虑到塑件形状和模具结构与成本,设计了沿塑件侧壁轮廓排布的圆推杆脱模机构;为避免气纹 、气穴等缺陷的形成,在型腔处设计了排气槽结构。该模具结构设计较为合理 ,可为其他结构相似塑件的模具设计提供有益参考和指导。 
Abstract:Moldflow was used to simulate the injection molding process of the plastic drainage pump filter, and the reasonable gate location and cooling water channel were determined by analyzing its structure. The effects of melt temperature (A), filling pressure (B), and mold opening time(C) on the warping deformation of plastic parts were studied by using three-factor and three-level orthogonal tests. The results show that the optimal combination of process parameters was obtained as A1B3C3, that is, a melt temperature of 220 ℃, a filling pressure of 80%, and a mold opening time of 6 seconds. At this time, the maximum warpage deformation of the plastic part is 0.632 8 mm, which is reduced by 10.37% compared with before optimization. Finally, according to the analysis results of Moldflow, UG software was used to design the structure of the injection mold. According to the structural characteristics of the plastic fastener, the cavity adopted the integral structure, and the core was designed into a combined structure, which is composed of the main core and sliders, and three groups of "inclined guide post + slider" type side core pulling mechanism were used to solve the demoulding problem. To realize the sequential demand, the nylon plugs were used to increase the opening resis‐ tance between the fixed formwork and the moving formwork, and a fixed distance parting mechanism with a built-in "small tie rod+ tie rod sleeve" structure was designed. Considering the shape of the plastic part and the structure and cost of the mold, a circular push rod ejector mechanism arranged along the side wall profile of the plastic part was designed. To avoid the formation of air marks, air pockets, and other defects, the exhaust groove structure was designed in the cavity. The design of the mold structure is reasonable and can provide useful reference and guidance for the mold design of other structurally similar plastic parts.
