三&#8231;拔块动作原理及设计要点
是利用成型机的开模动作，使拔块与滑块产生相对运动趋势，拨动面B拨动滑
块使滑块沿开模方向及水平方向的两种运动形式，使之脱离倒勾。
如下图所示：
<img src="attachments/dvbbs/20038122223899161.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122223899161.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
β=α≦25°　(α为拔块倾斜角度)
H1≧1.5W  　(H1为配合长度)
S=T+2～3mm　　(S为滑块需要水平运动距离；T为成品倒勾)
S=H*sinα-δ/cosα
(δ为斜撑梢与滑块间的间隙,一般为0.5MM；
H为拔块在滑块内的垂直距离)
C为止动面，所以拨块形式一般不须装止动块。(不能有间隙)

四&#8231;滑块的锁紧及定位方式

由于制品在成型机注射时产生很大的压力,为防止滑块与活动芯在受到压力
而位移,从而会影响成品的尺寸及外观(如跑毛边),因此滑块应采用锁紧定位，
通常称此机构为止动块或后跟块。
常见的锁紧方式如下图：

<img src="attachments/dvbbs/2003812225639305.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003812225639305.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />滑块采用镶拼式锁紧方式,通常可用标准件.可查标准零件表,结构强度好.适用于锁紧力较大的场合.




<img src="attachments/dvbbs/20038122261098623.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122261098623.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />采用嵌入式锁紧方式,适用于较宽的滑块





<img src="attachments/dvbbs/20038122271562464.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122271562464.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />滑块采用整体式锁紧方式,结构刚性好但加工困难脱模距小适用于小型模具.

五.滑块的定位方式
滑块在开模过程中要运动一定距离,因此,要使滑块能够安全回位,必须给滑块
安装定位装置,且定位装置必须灵活可靠,保证滑块在原位不动,但特殊情况下
可不采用定位装置,如左右侧跑滑块,但为了安全起见,仍然要装定位装置.常见的定位装置如下：


<img src="attachments/dvbbs/2003812234342690.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003812234342690.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />利用弹簧螺钉定位,弹簧强度为滑块重量的1.5~2倍,常用于向上和侧向抽芯.




<img src="attachments/dvbbs/20038122352859307.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122352859307.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />利用弹簧钢球定位,一般滑块较小的场合下,用于侧向抽芯




<img src="attachments/dvbbs/20038122363161667.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122363161667.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />利用弹簧螺钉和挡板定位,弹簧强度为滑块重量的1.5~2倍,适用于向上和侧向抽芯





<img src="attachments/dvbbs/20038122373959355.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122373959355.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />利用弹簧挡板定位,弹簧的强度为滑块重量的1.5~2倍,适用于滑块较大,向上和侧向抽芯.

七&#8231;滑块的导滑形式
块在导滑中,活动必须顺利、平稳,才能保证滑块在模具生产中不发生卡滞或
跳动现象,否则会影响成品质品,模具寿命等常用的导滑形式如下图所示。


<img src="attachments/dvbbs/20038122485021185.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122485021185.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />采用整体式加工困难,一般用在模具较小的场合。



<img src="attachments/dvbbs/20038122495569286.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122495569286.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />采用压板,中央导轨形式,一般用在滑块较长和模温较高的场合下。

八&#8231;倾斜滑块参数计算
由于成品的倒勾面是斜方向,因此滑块的运动方向要与成品倒勾斜面方向
一致,否侧会拉伤成品。
1.滑块抽芯方向与分型面成交角的关系为滑块抽向动模.
如下图所示：<img src="attachments/dvbbs/20038122573884190.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20038122573884190.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
α°=d°-b°
d°+b°≦25°
c°=α°+(2°-3°)
H=H1-S*sinb°
S=H1*tgd°/cosb°
L4=H1/cosd°


2.滑块抽芯方向与分型面成交角的关系为滑块抽向定模.
如下图所示：

九&#8231;母模遂道滑块
1.应用特点
a.制品倒勾成型在母模侧
b.制品外观有允许有痕迹
c.滑块成型面积不大
如下图所示：
<img src="attachments/dvbbs/2003812322919625.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003812322919625.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />


2.母模遂道块简图如下：

(3).设计注意事项
<img src="attachments/dvbbs/2003812385264031.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003812385264031.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
a. 上固定板的厚度H2≧1.5D  
    (D为大拉杆直径；大拉杆直径计算超级链接三板模大拉杆计算；H2上固定板的厚度)
b. 拨块镶入上固定板深度H≧2/3H2
c. 注口衬套头部要做一段锥度，以便合模。且要装在上固定板上，以防止成型机上的喷嘴脱离注口衬套，产生拉丝现象不便取出，影响下一次注射。
d. 拨块在母模板内要逃料。
e. 耐磨板要高出母模板0.5mm，保护母模板。以及支撑拨块防止拨块受力变形。
f. 小拉杆限位行程S≦2/3H1，以利合模。 (H1为滑块高度)
g. 拨杆前端最好装固定块，易调整，易加工，构成三点支撑，增加拨块强度。
h. 要使耐磨块装配顺利，要求点E在点D右侧。如下图所示：
i. 滑块座与拨块装配时，要特别注意尺寸B与B1的关系，应为B>B1，但为了
装配的顺畅，也可将其滑块座后模板部分全部挖通。
