Title: FAST SWITCHING DEVICE FOR EXTRUSION MOULD
Abstract:
Disclosed is a fast switching device for an extrusion mould, the fast switching device comprising a set of sliders provided at an outlet end face of the extrusion mould (1), and a driving mechanism for driving sliders (2, 3) in the set of sliders to move and then partially plug a cavity in the extrusion mould (1). Production is switched for products having a similar section via the driving mechanism by driving the sliders (2, 3) in the set of sliders to move and then partially plug the cavity in the extrusion mould (1), so that halt is not necessary and it is also not necessary to remount a mould during the switching, thereby reducing the scrap of products due to starting and debugging and the scrap of extruded materials, and also enabling the consistency between product batches to be increased, thus reducing the rejection rate.
