摘要：随着时代的发展，计算机领域和制造业领域的相互促进及中国制造2025强国战略的不断深化。更多的设计、制造、验证、分析的过程被计算机软件虚拟模拟而代替。NX作为一款先进的三维数字化机械设计类软件，其为模具行当提供了一套全面的解决方案Mold Wizard，能够极大的降低设计工作人员的工作量，PTS产品模板工作室可以服务于企业的特定需求，在不通过二次开发的前提下完成高度的定制化企业需求。68724
本次课题以NX11.0.0.33为例，根据齿轮特殊的精度要求和材料属性需求设计了一套注射模具，作为一个高要求的传动件，其模具两端各设计一个定位环，同时配备模温检测器、压力传感器和计数器等辅助原件；为了简化设计过程采用标准化的大水口模架；采用镶件以减少加工表面，降低成本；为方便分模时塑件能留在公模侧，设计了一对弹簧帮助分模；设计了单头的热流道配合潜伏式浇口，保证塑件表面质量的同时，减少材料浪费；通过分模验证和模流验证保障设计的可行性；设计了两个PTS模板，齿轮模板，可以通过修改基本参数实现产品额变形同时拟定了产品需求，即产品质量，产品在变形后可以自动检测设计是否通过验证满足需求；分模模板，可以是实现模具A、B侧的组件展开，便于观察。本设计采用NX设计软件，极大的方便了产品的设计过程，并且设计的模板在日后产品变形时仍具有一定作用。强大的验证模块起到了良好的辅助设计作用，改模具产品具有可行性强，贴合实际的特点，并具备一定的重用性。

Inject mold Design of gear
Abstract: With the development of the times, computer areas and manufacturing areas of interaction and the deepening of China's manufacture 2025 strategy. More design, manufacture, verification, analysis software by computer simulation instead. NX as an advanced three-dimensional digital mechanical design software, which provides a comprehensive solution for mold business Mold Wizard, can greatly reduce the workload of the staff, PTS product template Studio can serve the specific needs of the enterprise, without going through the secondary development of done without a high degree of customization to business needs. This times subject to NX11.0.0.33 for cases, according to gear special of precision requirements and material property needs design has a injection mold, as a high requirements of drive pieces, its mold ends the design a positioning ring, while equipped with die temperature detection device, and pressure sensor and counter, auxiliary original; to simplified design process used standardization of flood mouth die frame; used set pieces to reduced processing surface, reduced cost; for convenient points die Shi plastic pieces can left in male die side, design has pair spring help points die; Design has single head of heat road tie lurking type poured mouth, guarantee plastic pieces surface of while, reduced material waste; through points die validation and die flow validation guarantees design of feasibility; design has two a PTS template, gear whether through validation meet needs; points die template, can is achieved mold a,, and b side of component expand, easy observation. This design uses the NX software, greatly facilitates the process of product design, and design template variant still has a role in the future. Strong authentication modules play a good role in computer aided design, mold product having modified feasible, practical characteristics, and with a certain degree of reusability. template, can through modified basic parameter achieved products amount deformation while developed has products needs, that products quality, products in deformation Hou can automatically detects design whether through validation meet needs; points die template, can is achieved mold a,, and b side of component expand, easy observation. This design uses the NX software, greatly facilitates the process of product design, and design template variant still has a role in the future. Strong authentication modules play a good role in computer aided design, mold product having modified feasible, practical characteristics, and with a certain degree of reusability.
