In this paper, the forming techlonogy for the blanker slots of shell to linear bearing is analysed.

分析了直线轴承外毂架侧槽的成型工艺，并介绍了实现精密侧冲成型的模具结构，对模具关键零件凸模的结构及主要尺寸的设计进行了阐述，提出了设计要点。

The election of press process is based on consulting correlation datum and analyzing the form of manufactured product meticulous; The election of press die is based on synthesis considerations on economical efficiency、the processing property of part and complex degree iso many factors; Calculating the work blank of manufactured product unfold dimension is lined feed on the premise of calculation convenience but without contribution die confectioning simplified frequent application cast.

冲压工艺的选择是经查阅相关资料和和对产品形状仔细分析的基础上进行的；冲压模具的选择是在综合考虑了经济性、零件的冲压工艺性以及复杂程度等诸多因素的基础上进行的；产品毛坯展开尺寸的计算是在方便建设又不影响模具成型的前提下简化为所熟悉的模型进行的。

CONCLUSI ON :Theformulationinthe studyforthefirsttime combinedfourtypes of additivesincludingionic surfactant,non-ionic emul-sifier(Pluronic F-68 and Tween-80),andlecithinto obtainfavorably stable nanosuspension,which could stabilize for more thansix months without creaming.

Secondly, by the numerical simulation "experiments" and mechanics analyses, the effects of temperatures, forming velocities and the entering angles of mould on the products were studied. The main invaliding forms both of crinkling and crazing were simulated and analyzed, so that the technical parameters of forming, geometrical parameters of moulds were optimized.

其次，通过对TC1钛合金薄板整流内罩的深拉热成形的数值模拟&实验&和力学分析，探讨温度、成形速度和模具压边力等对成形产品的影响，模拟分析了&起皱&和&拉裂&等主要失效形式，对成形工艺参数、模具几何参数等进行了优化。

Rational injection and demould methods were determined,so did the design of loosing core,injection, demounting and cooling system.

因此在设计注塑模具时必须要特别注意，需要综合考虑模具的浇注系统、排气系统、冷却

My old metal casting mold assemblies were disassembled and used to keep my new molds snuggly in place.

我的旧金属铸造模具的集会被拆解，并用以保持我的新模具snuggly在的地方。

In January, 2008 Michael donated a 2005-06 Dodge Charger carved plaster body original, urethane mold pulled from the original and a copper electroformed body made from the urethane mold.

在2008年1月迈克尔捐赠了2005至06年度道奇Charger刻石膏机构原，聚氨酯模具拉从原来的和铜电铸体从聚氨酯模具。

Ask the important medium-sized fairly good area manufacturing industry enterprise owner who pushes forward middle , western part industrial foundation actively to assist separation , use whose mould workshop , branch factory within not very long time, adopt ways of effectively instituting multiple forms , change mechanism, energetically, develop a clearly established ownership , manage independently and with the initiative in one's own hands, the operation and mould adapting to a marketplace produce the quick response modern times special field mould enterprise , cultivate being able to represent horizontal industry "faucet" enterprise, drive the development that area estate enchains.

以前在学校的时候，我以为自己学到了很多专业方面知识，曾经还一度的认为自己不错，但是在工厂实习的这段时间以后，我才发现自己的缺陷和不足，而且还非常的缺乏经验，因为在学校的时候我们接触的都是些纯理论的专业知识，并没有与实践联系起来，所以我们对模具的认识只局限在表面上的感性的认识，而没有上升到理性认识的高度，换句话说就是还没有真正的认识模具这一名词的真正含义。但是只有实践还是不够的，经验才是最宝贵的。而对与我们这些刚刚走出大学校园的毕业生来说最缺乏的就是经验了。所以在实习的这段时间我吃了不少苦头

To ensure the quality and enhance the productivity, we have accomplished the optimization of mold structure and the simulation of melt filling and mold opening. In the end, the best case to solve processing problems and optimize mold structure and processing parameters is excogitated.

因此，为保证产品质量，提高生产效率，我们进行了模具结构CAE优化及充模、开模仿真，为解决实际生产缺陷、优化模具结构和工艺参数提供了最有效途径。

Introduce the order and debug of the plastics profile extrudes molding,emphasized to introduce the technique detail that the time that the order molding should notice,And the regulation of test and acceptance the molding.

着重介绍了模具订购时应注意的技术细节和模具调试及验收的注意事项。
