Abstract
The utility model relates to the metal press working field, in particular to a die of an extruding machine. The die comprises a die body and a through hole arranged on the die body, wherein the through hole comprises a metal feeding segment and a metal discharging segment; the feeding segment is a straight hole; the diameter of the discharging segment is increased gradually; the diameter of the leftmost end of the discharging segment is equal to the diameter of the feeding segment, and the diameter at the rightmost end thereof is equal to the diameter of an output metal product; the leftmost end of the feeding segment is provided with a pressurizing segment; the pressurizing segment is a hole with the diameter being decreased gradually, and the diameter at the right end of the pressurizingsegment is equal to the diameter of the feeding segment. The die has the beneficial effects that as the pressurizing segment is added at the left end of the feeding segment, the pressure of the metalmaterial in the feeding segment is higher, no hollow heart exists in the extruded product, and the quality of the extruded product is improved.
Description
Technical field
The utility model relates to the mould of stress metal manufacture field, particularly a kind of pressurizing unit.
Background technology
At present, the mould of existing pressurizing unit, comprise feeding-passage, shaping channel and tapping channel, feeding-passage is a straight hole, and tapping channel is a hole that diameter increases gradually, the stress metal that the mould of such pressurizing unit enters shaping channel is big inadequately, so the product of output is easy to generate hollow parts, influences the quality of product.
The utility model content
The purpose of this utility model is at existing pressurizing unit shaping channel stress metal above-mentioned big inadequately, the metal product of producing is easy to generate the problem of hollow parts, provides a kind of metal product of production the pressurizing unit mould of hollow parts can not occur.
The realization the technical solution of the utility model is as follows:
A kind of mould of pressurizing unit, comprise mold and the through hole that is arranged on the mold, this through hole comprises metal feed zone and discharging section, feed zone is a straight hole, the diameter of discharging section increases gradually, discharging section high order end diameter is identical with the diameter of feed zone, and low order end is identical with the diameter of the metal product of output, is provided with one section pressurized segment at described feed zone high order end.This pressurized segment is a hole that diameter reduces gradually, and the right-hand member diameter of pressurized segment is identical with the feed zone diameter.
The beneficial effects of the utility model make the metal material pressure that enters feed zone bigger for because increased pressurized segment at the feed end left end, and it is hollow that the product that squeezes out can not occurred, and improve the quality of extruded product.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure, 1 is mold, and 2 is feed zone, and 3 is discharging section, and 4 is pressurized segment.
The specific embodiment
Mould with reference to a kind of pressurizing unit shown in the accompanying drawing 1, comprise mold 1 and the through hole that is arranged on the mold 1, this through hole comprises metal feed zone 2 and discharging section 3, feed zone 2 is a straight hole, the diameter of discharging section 3 increases gradually, discharging section 3 high order end diameters are identical with the diameter of feed zone, and low order end is identical with the diameter of the metal product of output, are provided with one section pressurized segment 4 at described feed zone 2 high order ends.Described pressurized segment 4 is a hole that diameter reduces gradually, and the right-hand member diameter of pressurized segment 4 is identical with feed zone 2 diameters.
After the copper bar enters mould by squeegee roller rotation drive, will be by the shape of the extruding becoming of the through hole on the mold 1 final products, the through hole of existing mould comprises feed zone 2 and discharging section 3, feed zone 2 is a straight hole, the flaring hole that discharging section 3 increases gradually for diameter, the utility model has added one section pressurized segment 4 in feed zone 2 fronts on the basis of existing mould, the hole that this pressurized segment 4 reduces gradually for diameter, pressure can be bigger when entering feed zone 2 and discharging section 3 for metal like this, there is hollow problem in the product that can avoid squeezing out, improves the quality of extruded product.
Claims (2)
1, a kind of mould of pressurizing unit, comprise mold and the through hole that is arranged on the mold, this through hole comprises metal feed zone and discharging section, feed zone is a straight hole, the diameter of discharging section increases gradually, discharging section high order end diameter is identical with the diameter of feed zone, and low order end is identical with the diameter of the metal product of output, it is characterized in that: be provided with one section pressurized segment at described feed zone high order end.
2, the mould of a kind of pressurizing unit according to claim 1 is characterized in that: described pressurized segment is a hole that diameter reduces gradually, and the right-hand member diameter of pressurized segment is identical with the feed zone diameter.
