Description

注射压缩成形方法及其合模控制方法
本发明涉及注射压缩成形方法及其合模控制方法。
在注射压缩成形中，以往的合模控制是对合模力进行检测、并将其实测值与合模力的目标值之差反馈至电动机的转矩中进行的。
但是，在上述以往的注射压缩成形方法中存在以下问题。虽然高循环成形或快速硬化树脂成形的场合要求高速的合模控制，但由于以往的合模力控制方法是合模力检测装置在注射开始后对合模力进行检测并根据其实测值进行合模力的反馈控制，故存在无法与高速的合模控制对应且不能获得高复制程度的成形件。
另一方面，不仅要求短时间的成形获得高复制程度的成形件，并要求对花费时间的高精度的多种成形件进行注射成形。另外，在减速比因肘式机构或曲柄机构等的位置而变化的合模机构中，由于闭模位置附近的必要电动机转矩较小，一旦进行将合模力反馈到电动机转矩上的合模控制，控制的精度即变差。
本发明的目的在于提供一种通过缩短模具的开闭动作所需时间来提高成形件的质量并缩短成形生产节拍的注射压缩成形方法及其合模控制方法。
为实现上述目的，本发明的注射压缩成形方法及其合模控制方法的特点是对合模力进行检测、并与根据其实测值使速度指令值变动的合模力反馈速度控制合并进行对模具的位置进行检测并控制的位置控制。
更具体地说，是最初进行高速的位置控制，在可动模具到达预定位置的时刻将位置控制切换成合模力反馈速度控制。
或者，将速度确定为一定并最初进行使模具高速移动的一定速度控制，在合模力到达低于目标值的规定值的时刻切换成合模力反馈速度控制。由于各种成形件因树脂的状态千变万化、并且模具的温度也在变化，合模力也与此相应而变动。通过对微妙地跟随这种变动并可高精度微调的合模力反馈速度控制与高速位置控制或一定速度控制进行适当的切换，同时实现成形所需时间的缩短和高精度的成形。

以下参照附图说明本发明的注射压缩成形方法及其合模控制方法的一实施形态。
图1为注射成形机的结构的概略图。注射成形机具有模具10、模具开闭推顶机构7、控制装置8。模具开闭推顶机构7作为运动系统，系由经皮带4将从伺服电动机1传递的旋转运动变为横向往复运动的曲柄机构5和将该横向往复运动变为上下运动的肘式机构6组成。控制装置8对从作为设于系杆2上的合模力检测装置的变形传感器3来的模拟信号进行检测并对伺服电动机1的速度和转矩进行控制。模具10由沿系杆2安装于滑动自如的下台板9的下模10a和经上台板11安装于系杆2的上模10b组成。上模10b中设有注射作为成形材料的熔融树脂的喷嘴。
以下说明从注射开始至压缩的本发明的合模控制方法。
图1所示的注射成形机的控制装置8根据由变形传感器3来的模拟信号和由伺服电动机1的速度和位置信号向伺服电动机1输出速度和转矩指令。本发明的合模控制方法系与根据检测出的合模力进行指令速度的合模力反馈速度控制合并进行对模具的位置进行检测并控制的位置控制。
图2A-图2C为表示注射压缩成形的注射-压缩时的时间图。其中，图2A表示可动模具10a的位置的变化，图2B表示合模力的变化，图2C表示可动模具10a的速度的变化。
注射压缩开始时，控制装置8进行位置控制，并使可动模具10a以设定的高速度移动。一旦测得可动模具10a到达合模位置X1点，控制装置8即由位置控制切换为合模力反馈速度控制。合模力反馈速度控制中输出的速度指令值为测得的合模力与合模力的目标值之差的比例值。图3为本实施形态的合模控制方法的合模力反馈速度控制的方框图。F为合模力的目标值，F’为合模力检测装置测得的实测值。P为比例乘数，I为积分乘数，V为向伺服电动机输出的速度指令值。如图3所示，是补充F与F’的差乘以P的值和F与F’之差的积分值乘以I的值算出速度指令值V。由于合模力反馈速度控制是根据合模力的目标值与实测值之差的比例值算出速度指令值，可动模具的移动速度虽然不快，但能跟随合模力的微妙变化进行高精度的控制。
一旦根据这样求得的速度指令值V使可动模具10a移动且合模力到达目标值F1，即在指定的时间内维持合模力=F1的状态。然后，可动模具10a由合模力反馈速度控制沿与固定模具10b分开方向移动，其结果是合模力如图2B所示从比当初的F1值低的F2值进一步变化到比F2值更低的F3值。其间进行与成形件的成形状态的变化对应的合模力控制，并对成形件加以压缩成形。
一旦合模力到达F3值，控制装置8即由合模力反馈速度控制切换为位置控制。可动模具10a以设定的高速度移动并回到注射压缩成形开始时的位置，并结束注射压缩成形。
该合模控制方法由于在树脂注射开始时和注射过程中进行位置控制并使可动模具10a以高速度移动，然后切换为合模力反馈速度控制而以高精度进行树脂成形，再切换为位置控制而使可动模具10a以高速度移动，故成形精度不会降低，并能实现高速注射压缩成形。因此，如适用于高循环成形或快速硬化树脂成形，能获得高复制程度的成形件。
另外，如在冷却工序中进行合模力反馈速度控制，并花费时间将模具打开，则成形精度进一步提高。
另外，在通过位置控制使可动模具10a移动的期间，也可在合模力的实测值到达比目标值F1稍低的F1’值的时刻切换为合模力反馈速度控制。这样，能进行与树脂的成形状态的变化随时对应的合模控制。
以下参照图4A-图4C和图5说明本发明的合模控制方法。该实施形态的合模控制方法的特点是，在通过上述控制装置8进行一定速度控制并使可动模具10a移动的过程中，在到达合模力的实测值设定范围内的值的时刻将一定速度控制切换为合模力反馈速度控制。
图4A-图4C为表示注射压缩成形的注射-压缩时的时间图。其中，图4A表示可动模具10a的位置的变化，图4B表示合模力的变化，图4C表示可动模具10a的速度的变化。
注射压缩开始时，控制装置8进行一定速度控制，并使可动模具10a以一定的高速度V0移动。一旦合模力的实测值到达比设定的目标值F1低若干的-△F1，控制装置8即由一定速度控制切换为合模力反馈速度控制。由于切换为合模力反馈速度控制后可动模具10a的移动速度急剧降低，故实际的合模力不会超过目标值F1。
另外，如图5的方框图所示，如在合模力反馈速度控制中对速度设置上限，可防止可动模具10a移动过度。虽然速度指令值V是补充合模力的目标值F与合模力的实测值F’的差乘以比例乘数P的值和F与F’之差的积分值乘以积分乘数I的值算出的，但最好不超过预先设定的速度V0。
采用这种合模控制方法，由于模具移动速度的控制可相应于树脂的成形状态的变化引起的合模力的变动进行，故能在不会降低成形精度的情况下实现高速注射压缩成形。
如上所述，采用本发明的注射压缩成形方法及其合模控制方法，由于能缩短模具开闭动作所需时间，并相应于树脂的成形状态的变化引起的合模力的变动进行模具移动速度的控制，故能实现在提高成形精度的同时缩短成形生产节拍。
