Four to deepen grass-roots governance according to law1) 注塑机是在高温、高压和快速的工况下工作，所以安全生产很重要，安全生产包括人身安全、设备安全和物的安
全。安全才能促进生产。安全保护和防护装置对注塑机是很重要的，安全保护和防护装置有机械、电器、液压保护和防护罩。
2) 设有的安全保护装置：有熔断器、热继电器和空气开关等电器元件，为保护电器过载，也就是保护注塑机过载。
急停按钮，当注塑机发生故障或涉及人生安全时，按急停铵钮，注塑机立即停机。报警装置：有报警灯和蜂鸣器，显示屏能显示注塑机当时故障的报警内容。如料温偏差，油温偏差，全程未按时完成，托模进退没有到终位，储料未定时完成，润滑检出失败等等。例显示屏显示射出监控失败，报警灯闪烁，蜂鸣器响，这时必须将半自动转换到手动，报警停止等待排除故障，排除故障后转换到半自动即投入正常生产。射出监控失败，就是注射不到位，造成原因有储料量过多，料温或模温过低，注射压力低或速度慢，喷嘴头堵塞等原因，通过分析即能排除故障。当开冷车时，在手动工况下如实际料温不在设定的温度范围内，偏高或偏低，此时按预塑和注射触膜键，就无预塑和注射动作，（是有注塑机电脑内已设定保护参数起作用）防止开冷车或喷料。

Four to deepen grass-roots governance according to law3) 对人的安全保护和防护装置：有机械保护即锁模安全装置，在移动模板上装锁定螺母来固定保险杆，固定模板上
装档板和保险杆罩。当安全门打开，移动模板后移开模，保险杆从保险杆罩内移出，档板落下，如在安全门打开时其它闭模装置失灵，移动模板闭合时，保险杆随移动模板前进，很快保险杆就撞在档板上，阻止移动模板闭合，保护了操作人员取制品的手等。电器安全装置，急停按纽安装在电脑操作显示面板下面和对面防护罩上，各一只急停按钮。当注塑机发生故障或危及人身安全时，按急停按钮，即关油泵电机，停止所有工作动作，起紧急保护作用。行程开关装在主辅操作面固定模板上端各一只。在主操作面移动模板下端机架上装一只行程开关。三只行

行程
开关动作，移动模板闭合。这要任一扇安全门不关上，即有一只行程开关不动作，闭模电源不接通，注塑机不会合模，达到合模保护作用。液压保护装置在主辅操作面的二扇安全门下装有连动杆，在连动杆处，辅操作面安全门下的机架上装一只二位二通液压伐，当二扇安全门关上，连动杆脱开安全门，液压伐打开，控制压力油接通闭模电液伐，这时才能闭模。当其中任一扇安全门不打开，都不能闭模。
总之：机械、电器和液压三项措施保护闭模，这要其中有一项安全措施不失灵，就能控制不闭模，保护操作工在开模工况下取制品时不伤及人身。防护罩是防止注塑机移动部位不受外物掉落进去损坏设备和防止操作工不当心触摸到移动部位受伤。

一. 注塑成型机多级注射优点：
多级注射结合高速和低速注射的优点，能充分发挥注塑机成型性能，适应加工几何形状复杂的制品，适应流道和型腔各断面流动变化。能较好消除制品的注射纹、缩孔、气泡、汇笼线、烧伤等缺陷。
1. 高速注射优点：①缩短注射时间；②增大流动距离；③提高制品表面光洁度；④提高熔接痕的强度；⑤防止产生
冷却变形。
2. 低速注射的优点：①、防止产生溢边；②防止产生流动纹；③防止模具跑气跟不上进料；④防止带进空气；⑤防
止产生分子取向变形。
3. 多级注射效果：①缩短注射时间；②减少溢边缺料；③减少流动纹；④减少制品重量误差；⑤减少缩孔；⑥降低
锁模力；⑦减少制品表面光泽不均；⑧减少制品流痕，提高熔接强度；⑨防止制品烧伤；⑩减少弯曲（翘曲）及变形；11提高涂漆性和电镀牢度。
多级注射成形技术，不应利用调整注射压力来改变所需的注射速度，所以在确定注射压力时稍高一点，从而依改变速度的方法来调节，能较好的较快调节好成型制品。
二. 依据成型制品模具先择注塑机： 1.
依据成型制品的投影面积，重量和材质，结合模具的外形尺寸和顶出行程，选择合适的注塑机，在保证制品成型质量的同时还需考虑到成型制品的经济性。 2. 注塑机的主要技术参数：
1) 合模力、最大注射量、最大模厚和最小模厚、移模行程、拉杆间距离、顶出行程和顶出压力等。先择适应成型制
品的注塑机的技术要求，可按以下几条分：
2) 合模力：制品投影面积乘模具型腔压力≤合模力，Ｐ合≥QF型腔压力； 3) 最大注射量：制品重量<最大注射量。制品重量=最大注射量*75～85%。
4) 注塑机装置模厚:注塑机装模厚度友最大最小值二点间的区间。模具最大厚度注塑机≤最大模厚;模具最小厚度≥
注塑机最小模厚
5) 移模行程：模具开模距离=模具厚度+制品高度+顶出距离+取制品空间。即开模具模距离<移模行程。 6) 拉杆间距离：就是安装模具位置；模具长*宽≤拉杆距离
7) 顶出行程和压力：制品顶出距离和压力<注塑机顶出行程和压力； 其它：抽芯装置、气辅、干燥、模温机等。
