Description
本发明涉及挤压铸造技术领域，特别涉及一种串缸立式挤压铸造机。
挤压铸造是将一定量熔融金属液直接注入金属模膛，随后合模实现金属液充填流动，并在机械静压力作用下发生高压凝固和少量塑性变形，从而获得毛坯或零件的一种金属加工方法。目前，普通的立式直接挤压铸造机已用来大量生产合金铸件，带来了铸件品质的大幅提高，但普通的立式直接挤压铸造机只能提供一次直接挤压压力，在压制结构复杂的铸件时，这一压力并不能均匀地分布在挤压面上，无法保证整个铸件在有效挤压比压下凝固。特别是当铸件的不同部位在垂直方向上的厚度相差较大时：在直接挤压铸造过程中，厚度较小部位先于厚度较大部位凝固，从而导致挤压压力主要分布在厚度较小处，而需要在持续高压下凝固的厚大部位只能分配到较少压力，这种情况不利于厚度大的部位的成型和铸件整体性能的提高，特别随着铸件厚度差的增大，这一不利因素将更加明显。

第一次挤压；主驱动缸保压一定时间后，副驱动缸通过活塞杆带动第二挤压部向下挤压铸件厚度较厚的位置，副驱动缸增压并保压，使铸件厚度较厚的凝固部位仍在高压下凝固，实现对铸件的第二次挤压。通过该串缸立式挤压铸造机实现对铸件在竖直同方向的二次挤压，在铸件凝固过程中，根据铸件不同部位的凝固先后顺序，分阶段进行二次挤压，使挤压压力在合金凝固的过程中合理分布，提高了局部挤压比压和压力有效作用时间，有效地解决了厚度大的部位不及厚度小的部位的组织致密和晶粒粗大等问题，有利于厚度大的部位的成型和铸件整体性能的提高，提高产品质量和成品率；且该铸造机的驱动缸采用串联联动的方式，使整体体积小、结构更紧凑。
下面对技术方案进一步说明：
进一步的是，串缸立式挤压铸造机还包括顶板，顶板与副驱动缸的活塞杆连接，第二挤压部与顶板连接。副驱动缸的活塞杆通过顶板与第二挤压部连接，便于安装和维护。
进一步的是，第一模板和第二模板之间连接有导柱，动模板设有与导柱配合的导向孔。导柱对动模板的移动起导向作用，使动模板在上下移动过程中更稳定，避免发生偏移，也使合模精度更高。

进一步的是，驱动机构为升降液压缸，升降液压缸的活塞杆与动模板连接。
进一步的是，第一挤压部为上模芯，第二挤压部为围绕上模芯布置的上模环。使适应于中心厚度小，外圈厚度大的铸件的铸造，特别适用于涡轮的铸造，解决涡轮的外圈部位不及肋板部位的组织致密和晶粒粗大的问题。
进一步的是，上模具还包括上模架，上模架与动模板连接，上模芯固定于上模架上。
进一步的是，下模具包括固定于第二模板上的下模套、及固定于下模套上的下模芯，下模芯设有与上模芯和上模环配合的型腔。
进一步的是，主驱动缸的最大挤压力大于副驱动缸的最大挤压力。
进一步的是，主驱动缸和副驱动缸为液压缸。
与现有技术相比，本发明具有以下有益效果：
本发明通过该串缸立式挤压铸造机实现对铸件在竖直同方向的二次挤压，在铸件凝
