Specific embodiment
We make a kind of pipe tobacco conveying described in the utility model of copper alloy section bar extruding mould in conjunction with attached drawing below
Further instruction.
As shown in Fig. 1 to Fig. 5, a kind of pipe tobacco conveying copper alloy section bar extruding mould of the present embodiment, including by outer
The die ontology that die sleeve 1 and interior die body 2 form, the inner wall of the outer die casing 1 is equipped with the guiding groove 11 that axial length extends, described
The quantity of guiding groove 11 is two, and is symmetrical with 1 central distribution of outer die casing, and the outer wall of the interior die body 2 is equipped with and guiding groove pair
The guiding tendon 21 answered, the end face of the interior die body 2 are equipped with extrusion cavities 3, and the side of the outer die casing 1 is equipped with several threaded holes
12, the outer die casing 1 is fixed with interior die body 2 by threaded hole 12 and bolt, and the outlet end of the extrusion cavities 3, which is equipped with, does not advise
Molding port 4 then, the molding port 4 is made of the first arc port 41, the second arc port 42 and third inverse-arc shape mouth 43, described
The place molding end face 6 of molding port 4 is bolted with interior die body 2.The opening of the molding port 4 carries out fillet 5 and handles.Institute
State middle-end and terminal position that threaded hole 12 is distributed in 1 side of outer die casing.The side of the interior die body 2 is equipped with corresponding with threaded hole
Limit circular groove 22.The service condition of the mold is as follows: cooperating the screw hole of outer die casing end for outer die casing by fixing piece and squeezes
Machine is fixed out, and then interior die body is packed into outer die casing, threaded hole and corresponding limit by bolt cooperation outer die casing middle-end
For circle of position slot by outer die casing and interior die body fixation, entire die ontology is i.e. operable after the completion of connecting with extruder.Its
The thickness of middle molding end face is greater than the case where showing in attached drawing 3., since molding port is not conventional circle, rectangular configuration, and
It is more complicated polymorphic structure, in extruder work, the pressure and frictional force that the aperture position of molding port is subject to are larger, damage
Consumption is very fast, and replacement frequency is very fast, therefore, is effectively reduced by removably forming end face setting compared to entire mold is replaced
Cost effectively increases replacement efficiency, to improve production and processing efficiency, reduces due to only needing replacing molding end face
Operation difficulty.Fillet setting can reduce the consumption of molding port opening, and can generate burr in the process to avoid product moulding,
Improve section quality.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
