摘要
介绍了双层注塑结构及工作原理，指出了该模具的设计要点。该模具采用热流道技术，缩短了开模行程和成型周期；在成型面积和锁模力不变的情况下，一次注射两层制品，使生产效率提高近１倍；产品加工费用降低了４０％～５０％；节约主机投资。
The working principle of double layer injection mould is introduced in this
paper,pointing out the main point of the mould design.In this mould hot runner system
is used to reduce mould opening stroke and shorten moulding cycle.With the moulding
area and clamp capacity unchanged,the injection moulding of double layer product could
increase the production capacity by 100%,decrease production cost by 40%50%,cutting
down the investment for main machinery,and increasing the utilization ratio of the
machinery.
