浇注

The small formation holes in the brush cover was constructed with the mold core in moving and static container, and center ingate was employed to the gating system.

针对电刷端盖压铸件结构及工艺要求，选择端盖口部大端面为动静模分型面，铸件上各成形小孔由动静模型芯对接组成，浇注系统采用中心浇道。

Numerical simulation results show that the fluid flow in Lost Foam Process was different from that in an ordinary green sand mold, the molten metal flow forwards in a circular-arc shape from the ingate, meanwhile, the nature of the gating system influenced the filling process notably. As the polystyrene pattern decomposition has a strong quenching effect on the flowing metal fornt, a high temperature gradient was formed at the flowing metal front, this resulted in the dropping of temperature of the metal to the liquidus temperature quickly and decreased the flowability of molten metal, the temperature distribution in the metal behind, however, was even. The properties of the pattern and the coating affected the temperature distribution remarkably.

从内浇口开始，金属液呈放射状均匀向前充填，同时浇注系统性质显著影响金属液充型过程的流场；由于聚苯乙烯模样气化吸热对金属液的激冷作用，在金属液流端部区域产生很大的温度梯度，使得端部区域金属液很快降至液相线温度，降低了金属液的充型能力，而后续金属液中温度分布则比较均匀，模样性能、涂料性能显著影响这一温度分布特点。

The praguite fiber is ofen made into pitched block amd pasting on the surface of fiber, or into pouring material and casting on the surface of firebrick it is also used as head and thermal insultation material.

莫来石纤维常制作成纤维扎块粘贴在纤维表面或浇注料、耐火砖表面，用作高温隔热保温材料。

The primary and secondary windings and iron core are insulated by epoxy resin.

一、二次绕组及铁芯均浇注在环氧树脂内，耐污染及潮湿。

This improvement mainly reflected along the rolling direction, so that steel is no longer a certain extent, isotropic body; pouring the bubble was formed, cracks and loose, but also under high temperature and pressure have been welded together.

这种改善主要反映了沿轧制方向，使钢不再是在一定程度上，各向同性体；浇注泡沫形成，裂缝和松动，但在高温高压也被焊接在一起。

A somewhat different variety of this development at its finest can be found in the most modern asphalt wearing course construction method,"Stone Mastic Asphalt".

一种略为不同的各种这方面的发展在其优秀的可以在最现代的沥青身穿课程建设的方法，"石浇注式沥青"。

So near the end of the 60s, a new construction method for asphalt wearing courses emerged: what is known today as "Stone Mastic Asphalt".

如此接近60年代末，一个新的施工方法沥青身穿课程出现：什么是当今的"石浇注式沥青"。

The significance of this new construction method is clear when one considers that alone in Germany, over 200 million square meters of asphalt wearing courses paved using the Stone Mastic Asphalt construction method have been built.

的意义，这种新的施工方法是明确认为，当一个独自在德国，超过200万平方米的沥青铺设身穿课程使用石浇注式沥青施工方法已建成。

Epoxy resin is a kind of important thermosetting resin, because of excellent bonding and mechanical strength, electrical insulation properties, and widely used in electronic materials, packaging and coating, adhesive, composites matrix etc series of excellent performance and extensive use.

环氧树脂是一种重要的热固性树脂，因具有优异的粘结性、机械强度、电绝缘性等特性，而广泛应用于电子材料的浇注、封装以及涂料、胶粘剂、复合材料基体等方面一系列优异性能和广泛用途。

On how this text use advanced technical design make and mould plastics the mould summary, Upgrade and design method to mould plastics mould , settle well and mould plastics key of mold design -------Pour the system, carry and offer the system, cooling system side dividing into type and smoking the rational design of the core organization, In the hope of and discuss with colleagues together , make joint efforts and promote and mould plastics mould development of technology.
