Abstract

用超导性电磁装置(12)实现本发明塑料压铸机 工作元件(1a、4、5、6、11、19)的驱动。该超导性电磁 装置的导线(12a)由含钡、铜、氧和镧或钇的合金所制 成，并使用液氮作为使其达到所需跃变温度的冷却介 质。因此，驱动机器所需的电能几乎可以在毫无损耗 的情况下转换成机械运动或动力。

Description

本发明涉及一个带有工具部件、闭合部件、注射部件和各种辅助装置的塑料压铸机。
在现有技术的压铸机中，这些部件或装置中的所有或至少一部分各种可动或加压的工作元件是由液压装置驱动的，而液压装置又是由电动机带动的液压泵提供动力的。然而，也有的已知压铸机的工作元件全部是由电动机直接驱动的。以上两种体系虽有各种不同的实施方案，但它们都有一个共同的缺点，即当电能转换成直线的或者旋转的机械运动或动力时，都不得不产生可观的损耗，不管这种转换是在电动机上通过机械轴实现的，还是在液体驱动的压铸机中通过电机带动的泵和液压工作元件实现的。
因此，本发明的任务在于，用损耗极低的能量转换大幅度降低驱动塑料压铸机的所有工作元件或者至少一部分工作元件所需的能量。根据本发明可解决上述任务，即用超导性电磁装置驱动至少一部分工作元件，并用冷却介质将该电磁装置的导线冷却到跃变温度以下。
为此，至少要用超导性电磁装置驱动作线性运动的工作元件如可移动的工具夹板、推料器、芯件拉出器和注射装置的压紧圆筒，以及可轴向移动的蜗杆。然而，为了蜗杆的旋转驱动也可装设带有超导性电磁系统的电动机。
超导性电磁装置的芯子和线圈可装在一个壳体内，并由冷却装置向壳体供给冷却介质;也可以将电磁装置的导线制成管状体，并由冷却装置向管状体导入冷却介质。由于采用上述结构，输入导线线圈的电能在转换成机械运动或动力时几乎没有损耗。
附图描述本发明的实施例，其中：
图1为本发明塑料压铸机的轴向截面简图;
图2和图3为放大比例的超导性电磁装置的不同实施例的轴向截面简图。
图1所示的压铸机具有工具部件1、闭合部件2、注射部件3和作为辅助装置的推料装置4、芯件拉出装置5及压紧装置6。在该例中，闭合部件有一个肘杆2a，其一侧连接在一个固定的支撑板7上，另一侧与工具部件1的可动模具压板1a相连。该模具压板1a由横梁8支撑。横梁8一端被支撑板7支撑，另一端被固定的模具压板1b所支撑。靠工具部件1的两个模具压板1a和1b装有可拆卸的模件9a、9b。注射部件3具有一个蜗杆11，它可在被压紧在固定模具压板1b上的喷射园筒内作轴压移动和旋转运动。
在所示例中，所有可直线移动的工作元件，即由肘杆2a操纵的可移动模具压板1a、推料装置4、芯件拉出装置5和圆筒10的压紧装置6以及蜗杆11都由超导性电磁装置12所驱动。这些电磁装置具有内含线圈12a的外壳12b和一个带有伸出外壳12b的延长部分12d的芯子12C。电磁装置12的线圈12a经电控装置13、14、15与电源17相联，其中13、14、15又与主控装置16相连接。为了达到实现超导所必需的跃变温度，线圈12a必须由特殊的合金制成，而且必须冷却降温。该合金一般由镧、钡、铜和氧所组成，其中的镧也可用钇来代替。这种合金的跃变温度一般大于90K，因此可用液氮作为冷却介质。为了冷却线圈12a，设有与主控装置16相连的、并由液氮提供冷源的冷却装置18，该装置通过管道20与电磁装置12相连通。
在图1和图2所示电磁装置12的实施方案中，将各电磁装置的使压力和液体密封不漏的外壳12b通过管道20与冷却装置18相连接;而在图3所示实施方案中，则是把导线112a制成通入冷却介质的管子。电磁装置12的作为芯子延长部分的从动杆12d，相对于芯子12C是绝缘的，以使导向芯子的热传递保持尽可能低。
示例中用于驱动蜗杆11作旋转运动的电动机19也装有超导性电磁装置，而且也相应地与冷却装置18相连接。
显然，这些由线圈和可直线移动的可调芯子组成的电磁装置12可以被超导性直线电动机或者被附有使旋转运动转换成直线运动的装置的超导性回转式电动机所代替。然而，在任何情况下，由于超导性，用于驱动压铸机工作元件的电能基本上可以毫无损耗地转换成机械运动或动力。
