Abstract
The top stem casing that this utility model provides, body arranges the assembly cavity that cylinder is vertical with shoulder, and taper assembly cavity is taper, and so easily the extrusion in extruder connects and assembles stable；And taper assembly cavity is cylinder, shoulder is planar annular, and two sides is vertical, thus can guarantee that taper assembly cavity ensure that extrusion molding seals and fills type smoothly, and the little material surface so making to draw of mantle friction degree is smooth；It is provided with six reinforcements in the bottom of top stem casing so that top stem casing entirety more fastens firmly, is difficult to be extruded material and breaks through, and the life-span is longer simultaneously.
Description
Technical field
This utility model relates to a kind of top stem casing.
Background technology
Top stem casing carries out moulding extruding with push rod is supporting for extruder.In prior art, the structure existing defects of top stem casing, it is easily broken when being in particular in body extruding thin with extruder connecting portion structure, contact site is that plane is difficult to link up with extruder be connected.
