注塑模具弹簧是否可以经过150摄氏度处理,韧度各方面怎样?

Along with the our country mold industry rapid development,the moldprofession inevitably faces highly effective,is being precise,andthe globalization development.But casts the mold to take in the moldprofession one of most important units,also will certainly to ahigher level to develop.It also can be more and more important to ourcountry economy influence.Washes floods the bottle cap is in the daily life,extremely commonone kind of plastic packing product.This mold design even if obtainsfrom this common plastic product,introduced washes floods the bottlecap to inject the mold the unique feature,as well as three minuteorganizations mold movement processes.Used has pulled the materialpole to be located in decides the mold to pour the system,caused theworkpiece and pours the system reliable separation.Simultaneously thearticle introduced through this example the plastic injects the moldthe design process,further explained designs in the mold in the idea,should boldly have,nimble,the broad thought ability importance.Essential character:三板mold; Double drawing of patternsorganization; Two levels of drawing of patterns organizations;

　　Moldflow是一款模拟仿真分析软件,能够优化塑料零件、注塑模具和成型过程,为实际设计提供指导.本文利用Moldflow软件对键盘外壳进行纤维取向的分析.分别分析材料、注塑工艺、纤维含量对纤维取向的影响；以及纤维含量对注塑成型过程的影响.
　　Moldflow, a simulant and emulational analysis software, can optimize plastic hardware, injection moulds and molding processes and provide a practical design with direction. By means of the Moldflow, this paper makes some analysis on the fiber orientation to the keyboard case and analyzes the influence on the fiber orientation by the material, the molding technics and the fiber content respectively and the influence on the process of injection molding by the fiber content,
　　分别选取填充20%GF的ABS、PPV、PP材料,在相同的工艺条件下,20%GF在三种材料中,平均纤维取向以及纤维取向张量受材料分子结构的影响均有所不同.

　　Respectively select the filler materials ABS, PPV and PP of GF and on the same technics term, the tensors of 20% of GF’s average fiber orientations of the three materials are different from each other because of the influence from their respective molecular structures.

　　选取PC+ABS+20%GF材料,分别改变模具温度、熔体温度,平均纤维取向均有所变化,纤维泊松比为0.4219,定值不变,而纤维取向张量只受熔体温度影响.

　　Select the material PC+ABS+20% of GF and alter the temperatures of the mold and the fusant respectively, and the average fiber orientation has somewhat change: the Poisson's ratio of fiber is 0.4219 and the Fixed value is the same while the tensor of the fiber orientation is only influenced by the temperature of the fusant.

　　选取聚丙烯（PP）材料分别加入不同比例的玻璃纤维（GF）,在相同工艺条件下,随着纤维含量的增加,平均纤维取向呈先减小后增大的趋势变化；制品变形量呈减小趋势,但当纤维含量为35%时,变形量急剧增大,之后又呈减小趋势.

　　Select polypropylene (PP) and add to different proportional fiber-glass, and, on the same technics terms, the average fiber orientation shows a trend to change to decreasing first and increasing later as the fiber content is increasing; although the finished product shows a decrescent trend, the deflection increases rapidly when the fiber orientation is 35% and then it shows a decrescent trend once more.
　　

推板与型芯做斜面配合；耐用不易跑披锋.间隙一般0.01mm单边.具体跟注射用塑胶料,成型条件,产品结构等有关系.

应该是加胶的意思 比如注塑的产品在厚度或尺寸 上的增加,用加胶的方法达到品质 装配的要求.

1．单分型面注塑模;
2．双分型面注塑模;
3.带有侧向分型与抽芯机构的注塑模;
4．带有活动成型零部件的注塑模;
5.自动卸螺纹注塑模;
6.无流道注塑模;
7.直角式注塑模;
8.脱模机构在定模上的注塑模.

三角函数算出来的垂直距离是顶出行程,是动模底部到上顶针板的距离

It is not economical if we die sink only 100 pieces of products,we can make them through rapid prototyping.

壁厚3mm就差不多了,关键是要加筋位以防拔模时变形的；1KG的压力?点受力和面受力相差很大

在立式注塑机上,定模在上面,动模在下面.在定模上,两个半圆凹模合成一个杯子的外形,在动模上,一个凸模形成杯子的内腔.当定模的两个半圆凹模合在一起时,动模上的凸模和凹模合在一起,形成一个整的杯子的形状.两个半圆的凹模的动作是由滑块、斜导柱带动的.滑块在定模上,斜导柱在动模上,当动模动作时,斜导柱带动定模的滑块前后移动,形成合模、开模的动作.
