摘 要
通过对飞机模型的工艺分析和相关参数的计算,选用注塑成型方式制造.选定注塑机的型号为XS-ZY-125并采用一模一腔的注塑模式进行加工.结合飞机模型的结构特点,选用平直分型面,便于脱模.浇口形式采用点浇口,保证成飞机模型的质量和外观且自行拉断容易实现脱模时的自动化.在对飞机模型的尾架盲孔进行成型时,采用常见的侧向分型与抽芯的方式,同时,设计计算了型腔尺寸.飞机模型的推出机构采用常用的推杆推出机构,并选用导柱导套的合模导向机构.在软件应用方面,综合运用Auto CAD、UG软件,对飞机模型注塑模的整体结构进行设计和分析,绘制出飞机模型三维零件图和模具装配图,生成二维图,清晰的表示了飞机模型注塑模的各部分的结构和装配关系.在模具辅助加工方面,制定了动模上的型腔加工工艺路线,确定了铣刀、进刀量加工余量等.

Abstract (ztlthb)
Based on the technical analysis and calculation of related parameters of the model airplane, the corresponding injection molding manufacture process was selected.The selected
plastic injection moulding machine model was XS-ZY-125 and the injection mode of one mold to one model was adopted in the production.(ztlthb)
Considering the structural characteristics of aircraft models, flat parting surface was adopted as it was easy to release the mold.(ztlthb)
Point Injection mouth was the type used in the injection, which guaranteed the quality and
appearance of the aircraft model and it could pull off easily when releasing so it was easy to realize the automation.For the molding of the tail of the aircraft model the commonly used lateral parting type and the core-pulling operation were employed. At the same time,
design and calculation of cavity size were conducted. The Launching mechanisum was the commonly used push lever design combined with the clamping of the guide pin bushings guiding mechanism. In terms of software applications, integrated application of Auto
CAD, UG software to design the overall structure of the injection mould for the aircraft
model and analysis was introduced. The three dimensional parts and tooling assembly
drawing of aircraft models and a two-dimensional graph could be quicly generated with the software, which could clearly illustrate the aircraft model, the structure of injection
mold parts and theassembly. In terms of mould processing, the development of a dynamic
simulation of cavity processing was designed with detailed determination on the amount
of milling cutters, feed allowance.(ztlthb)
