开模

First, based upon the fields in the single cavities, open and short modes are constructed, whose coupling holes on disks are shorted magnetically and electrically respectively. Second, the whole field in the chain is expanded with the short and open modes. With the Galerkin method and the second vector Green theorem, it is possible to describe the physics problem by a simple general eigenvalue matrix equation. Here, the dispersion curves in periodical structures are available.

它首先利用有限元等方法计算各加速单腔中的电磁场，根据一定规则构造成所需的开模和闭模，然后把整个长腔链加速结构中的场用这些开模和闭模展开，再利用伽略金方法和第二矢量格林定理进行数学变换，考虑各模式在加速腔壁和腔间耦合孔处的边界条件后，就能把加速结构中电磁场用数学上的广义本征值矩阵问题描述，从而能够得到所求的色散曲线和电磁场形态。

Hexagonal bolts are usually formed with cold heading. The process is classified as open-die forging and therefore its die design is less complicated. The mushroom-like head has to be sheared into hexagonal shape and the amount of the scrap is somehow significant especially for heading with short bolts or high alloy material. There is an increasing demand in increasing the gross profit by increasing the yield of workpiece material.

六角螺栓头端通常以冷间顶铁成形製程来製造，由於冷间顶铁属於开模锻造，模具设计较容易，但需以剪缘模再对蕈状头端冲剪成为六角头，此剪缘后的废料量不容忽视，尤其对於长度较小的螺栓，或其它应用於紧扣件的高级合金而言，藉由减少废料以提高產品毛利的需求日益迫切。

Analyzed the structure characteristics of the perfume cover outer shell plastics piece, described the piece's structure and work principle which model a craft and inject a mold, its principle :adopt and certainly be apart from bolt and spring coil and carry on two cents type, use inclined lead a side outside the pillar and take out heart, type the heart crest spare parts, while entering and anticipating adoption incubate the type sprinkle into anticipate a form, while opening a mold, with the ball head pull and anticipate a pole sprinkle and note system and anticipate, then make use of and take out and push plank and release a plastics piece inside a heart,use spring coil and reset first while matching a mold, then carry on willing model a beginning next time.

摘要分析了香水盖外壳塑件的结构特点，叙述了该塑件成型工艺、注射模的结构和工作原理，其原理是：采用定距螺钉和弹簧进行二次分型，用斜导柱外侧抽芯，型芯顶出零件，进料时采用潜伏式浇口进料形式，当开模的时候，用球头拉料杆把浇注系统凝料顶出，然后利用型芯内抽推板推出塑件，合模时用弹簧先复位，然后进行下一次成型开始。
