Abstract During an injection moulding process, it is very diffi-cult to achieve efficient and balanced cooling. It is also difficultto generate an optimal cooling design for industrial parts automatically.In this paper, a milled groove insert method in mouldcooling was proposed for cooling of medium and large plasticparts. The advantages of this method include a better cooling effect,ease and flexibility of design, characteristics of auto-designand considerable savings on the coolant flow rate. A household
iron part was studied and the assemblies were modelled. Thecooling analyses of the mould assembly and thermal stress analysisof plastic parts were performed using ABAQUS/Standardto compare the proposed method to the most popular straightdrilledcooling channel method. The thermal stress analysis wasrun, consequently, based on the result of the cooling analysis.Simulation results have confirmed the merits of the milledgroove insert method.

摘  要

   在注射模具过程期间，达到有效的和平衡的冷却是非常困难的。指定为工业零件自动地生产一个最优冷却方法也是困难的。在这篇文章中，加工沟槽插入方法在模具冷却时打算用工具和大的塑料零件冷却。这种方法的优势包括一个更好的冷却效果，设计容易而且灵活，有自动设计的特征和在冷却流动速率上相当的节省材料。一个家庭的铁零件被研究和作为模型的装配。模具组装的冷却分析和塑料零件的热压力分析是通过使用ABAQUS/标准完成计划的方法成为最流行的横木冷却渠道方法。热压力分析被运行，基于冷却分析的结果达到一致性。模拟器的结果已经证明了沟槽插入方法的优点。
