Abstract
The utility model discloses a kind of improved aluminum sectional material mould.By the way that the work band of outer die cavity is divided into some sections, the length of each section of work band is different, and each work interband is connected with fillet, tap hole is arranged to gradually expand along the direction of extrusion, and it is arranged to the smooth surface transition gradually to be drawn in along the direction of extrusion at the neck position for being connected the core with the lower mould, so as to not set material guide groove at neck position.This avoid the accumulation of aluminium in material guide groove, flow velocity slowly causes extruded product temperature difference.So as to avoid in Surface of profile formation bright line, it is ensured that the quality of Surface of profile.
Description
Technical field
The utility model is related to extruding die for aluminum shaped material field, more particularly to a kind of improved aluminum sectional material mould.
Background technology
Usual aluminium section bar is that aluminum alloy materials are pressed through after aluminium section die on extruder to obtain.Produce hollow type
Generally shunting aluminium section die is used during material.As shown in figure 4, what its lower mould of common shunting aluminium section die was connected with core
Material guide groove 1c is provided with the 1b of neck position, for supplementing feed, so as to avoid causing section bar segmental defect due under feeding.But this
Sample can cause aluminum amount in groove many again, and flow velocity causes extruded product temperature difference slowly, form Surface of profile bright line, have impact on Surface of profile
Quality.
Utility model content
In order to overcome drawbacks described above and not enough the utility model to provide following technical scheme：A kind of improved aluminum sectional material mould
Tool, the aluminium section bar includes upper die and lower die, and the upper mould is provided with outer die cavity, and the lower mould is provided with core, and the lower mould enters
Expect that end is provided with some tap holes, the tap hole gradually expands along the direction of extrusion, the neck position that the core is connected with the lower mould
The smooth surface transition gradually drawn in along the direction of extrusion is sentenced, material guide groove is not set, the work band of the outer die cavity is divided into some sections,
The length of each section of work band is different, and each work interband is connected with fillet.
Preferably, the side of the upper mould, which is provided with, carries nib.So facilitate the handling of mould.
Compared with prior art, the utility model has the advantages that：If by the way that the work band of outer die cavity is divided into
Dry section, the length of each section of work band is different, and each work interband is connected with fillet, and tap hole is arranged to gradually expand along the direction of extrusion
Greatly, and by the core it is arranged to the smooth surface mistake gradually to be drawn in along the direction of extrusion at the neck position being connected with the lower mould
Cross, so as to not set material guide groove at neck position.This avoid the accumulation of aluminium in material guide groove, flow velocity slowly causes extruded product
Temperature difference.So as to avoid in Surface of profile formation bright line, it is ensured that the quality of Surface of profile.
Brief description of the drawings
Fig. 1 is upper mould front view in the utility model embodiment.
Fig. 2 is lower mould front view in the utility model embodiment.
Fig. 3 is lower mould complete section right view in the utility model embodiment.
Fig. 4 is mould complete section right view under shunting in the utility model background technology.
Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is elaborated.
As shown in FIG. 1 to 3, a kind of improved aluminum sectional material mould, the aluminium section bar include upper mould 2, lower mould 1, it is described on
Mould 2 is provided with outer die cavity, and the work band of the outer die cavity is divided into some sections, and the length of each section of work band is different, and the band that respectively works
Between with fillet be connected.The side of the upper mould 2 is provided with and carries nib 2a.The lower mould 1 is provided with core 1b, and the lower mould 1 enters
Expect that end is provided with some tap hole 1a, the tap hole 1a gradually expands along the direction of extrusion, and the core 1b is connected with the lower mould 1
Neck position at smooth surface transition gradually to be drawn in along the direction of extrusion, material guide groove 1c is not set.
Compared with prior art, the utility model has the advantages that：If by the way that the work band of outer die cavity is divided into
Dry section, the length of each section of work band is different, and each work interband is connected with fillet, and tap hole is arranged to gradually expand along the direction of extrusion
Greatly, and by the core it is arranged to the smooth surface mistake gradually to be drawn in along the direction of extrusion at the neck position being connected with the lower mould
Cross, so as to not set material guide groove at neck position.This avoid the accumulation of aluminium in material guide groove, flow velocity slowly causes extruded product
Temperature difference.So as to avoid in Surface of profile formation bright line, it is ensured that the quality of Surface of profile.
The utility model is described in detail above, but the utility model be not limited to it is described herein specific
Embodiment.It will be appreciated by those skilled in the art that in the case of without departing substantially from the utility model scope, can make other changes and
Deformation.Protection domain of the present utility model is defined by the following claims.
