Abstract
The utility model provides an extrusion molding mould of soft aluminium ribbon line, it can solve the problem that the aluminium ribbon line tensile strength who adopts current extrusion molding mould processing can't reach the requirement. It includes outer die sleeve and interior mold core, and interior mold core is installed in outer die sleeve, and ascending recess has been offered to the bottom surface of interior mold core, and the recess forms the extrusion die cavity with the bottom conical surface of outer die sleeve.
Description
Technical field
The utility model relates to the processing tool field of plain conductor, especially relates to the processing tool of soft flat aluminium wire, is specially a kind of mold for extruding and forming of soft flat aluminium wire.
Background technology
The extrusion molding of metallic conductor is that metal blank is put into extrusion die chamber, under the effect of high temperature and pressure, extrudes from specific extrusion die, thus obtains the metallic conductor of certain size and cross sectional shape.Existing flat aluminium wire extrusion die is shown in Fig. 1 and Fig. 2, it comprises outer die casing 2 and inner mould core 7, inner mould core 7 is installed on the bottom of outer die casing 2, the flat bottom surface 6 of inner mould core forms extrusion die cavity 5-1 with the bottom conical surface 4 of outer die casing, and its tensile strength of flat aluminium wire adopting the extrusion process of existing flat aluminium wire extrusion die to obtain is about 75N/mm
2, the tensile strength that cannot meet current soft flat aluminium wire cannot reach 50 ~ 65N/mm
2instructions for use.
Summary of the invention
For the problems referred to above, the utility model provides a kind of mold for extruding and forming of soft flat aluminium wire, and it can solve and adopt the flat aluminium wire tensile strength of existing mold for extruding and forming processing to meet the requirements of problem.
A kind of mold for extruding and forming of soft flat aluminium wire, it comprises outer die casing and inner mould core, described inner mould core is installed in described outer die casing, it is characterized in that: the bottom surface of described inner mould core offers groove upwards, and the bottom conical surface of described groove and described outer die casing forms extrusion die cavity.
Further, described inner mould core comprises the first core rod, the second die sleeve, the 3rd die sleeve and the 4th die sleeve, the end face of described first core rod is flush-mounted in the bottom groove of described second die sleeve, the top stage face of described second die sleeve is flush-mounted in the bottom groove of described 3rd die sleeve, and described 4th die sleeve is installed on described 3rd die sleeve.
Further, groove upwards described in the bottom surface of described first core rod offers, the bottom recesses of described first core rod and the bottom conical surface of described outer die casing form described extrusion die cavity.
The beneficial effects of the utility model are: because it to offer groove upwards in the bottom surface of inner mould core, thus the volume of extrusion die cavity that the bottom conical surface increasing this groove and outer die casing is formed, the increase of this extrusion die cavity volume can make metal blank at high temperature under high pressure by improving the temperature of extrusion die cavity during this extrusion die cavity, thus makes that the flat aluminium wire of each extrusion molding becomes softer, tensile strength reduces.
