Description
Technical field
The utility model relates to bar extrusion equipment, particularly a kind of center foaming bar rod-extruding machine head.
Background technology
At present, center foaming bar rod-extruding machine head has following effect aborning: 1, make viscous state material become parallel lines motion from screw, and stably introducing port mould and being shaped; 2, produce back pressure, make the further homogenizing of material, improve quality of item; 3, necessary briquetting pressure is produced, to obtain the closely knit and shape goods accurately of structure.
The cooling of existing center foaming bar rod-extruding machine head arranges cooling water pipe extruding exit, and this type of cooling can not control the foaming layer temperature of bar, and the quality causing bar to be extruded exists the phenomenons such as foaming is incomplete.
Summary of the invention
The purpose of this utility model is the defect for prior art, provides the center foaming bar rod-extruding machine head of simple, the adjustable foaming degree of a kind of structure.
A kind of center foaming bar rod-extruding machine head of the present utility model, comprise the inner core die of from inside to outside coaxial line device, outer core and handpiece body, the appearance surface cover of handpiece body has one deck heating collar, there is between inner core die and outer core bar foaming layer gap, there is between outer core and handpiece body bar wall thickness gap, the side of handpiece body connects the first extruder, the extrusion of the first extruder is communicated with bar foaming layer gap, the opposite side of handpiece body connects the second extruder, the extrusion of the second extruder is communicated with bar wall thickness gap, a cooling water cavity is provided with in described inner core die, the opening of cooling water cavity is provided with a chamber plug, described chamber has water inlet pipe and outlet pipe beyond the Great Wall, the bottom of cooling water cavity is stretched in one end of water inlet pipe.
In technique scheme, described inner core die and outer core are all fixed by screws on handpiece body.
Described handpiece body is provided with a thermocouple.
The bottom outer surface of described outer core can for shrinking shape opening.
The bottom outer surface of described outer core can be expansion shape opening.
Compared with prior art, the utility model has the advantages that: the utility model arranges cooling water cavity in inner core die, cooling water enters cooling water cavity, until after filling cooling water cavity, flowed out by outlet pipe, controlled the temperature of inner core die by the inlet of controlled cooling model water, cooling water influx is larger, the heat taken away is more, cooling effect is better, and foaming is just slower, and abscess is also less, foaming is also incomplete, otherwise otherwise.The thickness of foaming bar can come by changing outer core, if select the outer core shrinking shape opening, foaming bar is outer just thick, selects the outer core of expansion shape opening, and foaming bar is outer just thin.This handpiece structure is simple, the foaming degree of bar is adjustable, and can prepare multiple different bar.
