摘要
论述了导纸轮注塑模的模具结构特点和工作原理。该模具一模一腔,二次分型,4处点浇口进浇,侧凹拉断点浇口,模外抽芯,双推出结构。实践证明,该模具设计合理、动作可靠、实用性强。
The mold structure characteristics and the operational principle of injection mold for guide paper roller were discussed. One mold cavity, twice cavity parting, double-ejection device and core-pulling outside were adopted on the mold with four pin-point gates. The pin-point gates were broken by reentrants. The mold is rational in design, reliable in operation and strong in practicability.
