铰笔刀外壳注射模设计
摘 要： 随着各种性能优越的工程塑料的不断开发，注射工艺越来越多地用于制造领域成型各种性能要求的制品。注射模具的设计质量、注射机应用等直接影响成型制品的效率、质量及成本。目前单型腔、简单型腔的模具达70%以上，仍占主导地位。本次设计的塑件（铰笔刀外壳）比较小。通过对多种相似塑件的模具结构参考，同时为了提高生产效率，采用了一模四腔的平衡式布置的模具。由于塑件本身的结构，采用斜导柱侧向抽芯机构，不但使模具布局合理，而且解决了出模难的问题。本设计模具结构紧凑、合理，且便于加工、制作、装配、调整。

Design of injection mould for the crust of reamer
Material processing and control engineering Yeyanfen Tutor Liuhoucai
Abstract： With the development of engineering plastics with superior properties, the craft of injective mould more and more was used to shape product while accessed properties met with the requirement in the manufacturing field. The designing quality of injective mould and the application of injective machine ect. directly effect the coefficience ,the quality and the cost for formative product . The mould with simple cavity reaches above 70%, still occupied the dominant position up to now. This design models (the crust of reamer) quite small. compared to many kinds of models with similar structure in reference paper . The mould with four cavities was layouted in the balance position in order to enhance the productive coefficiency . Because models itself structure, the slanting guide with lateraed loose core and the slanting slide with lateraed loose core were used in this design . the problem of difficult demoulding was resolved.The design of mould had a compact and feasible conformation and was easy in processing,assembling and adjusting.
