调节挤出吹塑口模间隙的液压伺服系统

Hydraulic Servo System for Adjust The Clearance of Blow Moulding Die

在中空塑料容器的挤出吹塑成形中，只有主动调节机头口模间隙，使挤出坯料各部分按制品的需要具有不同的厚度，才能保证得到均匀壁厚的制品。本文将介绍一种对带有轴向和径向壁厚控制装置的挤出机头进行主动调节的多路液压伺服控制系统。

During blown moulding plastic vessel, product with even wallthickness is pledged to be producted by adjust the clearance of die that makes the pavision had different wallthickness which is demanded by the product.A mulit paths hydraulic servo system for adjust extruder head with a wallthickness control unit on axial and radial is introduced in this paper.
