【正文】 and the inclined angle in the cavity plate is 15176。生產(chǎn)工藝原理”。2002。[3]很多的鑲嵌件和標準零件被用于注塑模具。注塑成型機的頂出桿只需要移動120毫米。是一個模具的兩腔和側(cè)澆口的布局，10個抽芯機制如圖的的設計，是合理的，機構緊湊的。斜頂桿的耐磨性能非常的好，通過分析和計算，斜導桿的傾斜角度是20176。當模具打開的時候, 斜頂柱被固定在固定的模具中間，引導下滑到模具的一半，運動沿著下滑道滑動，與其配對的斜面腔板能夠確保劈滑動作用，當模具關閉的時候。相應的抽芯機制設計應在5個地方?；脽羝?，脫模以下是兩個汽車發(fā)動機的表面，如圖，1。機械、汽車制造、華南理工大學、中國廣州,510640 4深圳市重點實驗室的先進的模具制造技術、深圳大學、中國深圳518060 電子郵件: 摘 要： 對兩個汽車發(fā)動機構造特征、形成進行了分析。對注塑模具的結構設計與兩腔和工作過程的進行了探討。塑料配件開始被大規(guī)模生產(chǎn)成兩個塑料的部件，而且是要被塑造成一個模子。在F,H,G的塑料第二部分區(qū)域里，有三種構造，I和J的塑料第二部分在這三種構造里有六個凹進去的限制，在五個地方，相應的corpulling機制也應設計成一樣?？紤]到模具結構及工藝參數(shù)的問題, 這個傾斜角的角度被定為13度，斜板的角度被定為15176。這樣的角度可以確保實現(xiàn)抽芯和的受力分布。圖6如下：整個模具工作過程如下：融化塑料流入型腔模具通過澆注系統(tǒng)，在全部填充滿后，模具才打開。當脫模器停止運動后，塑料零件就會被取出來。所以， 注塑模具的經(jīng)濟效率非常的好,而且注塑模具的維修比較的容易。史、柯正龍”,國立中山大學電機,問陸g。于216:1523年。制造工程師學會。. The slide and theponents which are in touch with the slide are easy to wear because the slide moves frequently. In order topostpone wearing the ponents, the two steps are adopted as follow: The slide is made of 718H and is quenched to 50HRC around. The wear plates are laid on the bottom of the slide and on the back of the slide. The wear plates are madeof GS2510 and are quenched to 60HRC around. The slide way is formed by the slide wedge and the core plate. The slide way is easy to machine and to maintain.1. slide 2. fixed block 3. locking block 4. angle pin 5. wearplate 6. positioning screw plate 8. slide wedge 9.spring rodFigure 3.

DESIGN OF ANGLE EJECTOR ROD COREPULLINGMECHANISMSFour angle ejector rod corepulling mechanisms are designed in the area of D and E of the plastic part 1 and inthe area of I and J of the plastic part 2. The mechanisms are distributed in figure 4. Distribution of angle ejector rod corepullingmechanismsTaking the angle ejector rod corepulling mechanism 1 shown in figure 4 for example, the mechanism is mostlyposed of angle ejector block 1, angle ejector rod 9, angle ejector guide block 4, angle ejector guide block 6, angle pin 5, angle ejector slide 7 and wear plate 8.
