摘要
本文阐述了塑料注射成型时，型腔内温度的不均匀所产生的应力，对制品有害，分析了温度集中较高的地方，如塑料拐角、模具浇口、厚壁部分、细长型芯等处，提出了修正热流量的措施。
This paper describes stress produced due to uneven temperature in mould chamber in plastic injection forming.It may harm the product.The author also analysis spots where temperature concentrated higher,such as plastic corner,mould pouring mouth thiek wall,slender mould cove etc.Put forth measures for correcting thermal flow.
