The invention discloses a rod extruding die structure which comprises a rod extruding die upper die, a punch and a rod extruding die female die, wherein the punch is arranged on the rod extruding die upper die, the rod extruding die female die comprises an upper female die, a lower female die, a female die guide sleeve and an extruding opening, the lower female die can be detachably fixed on the bottom surface of the upper female die, a through hole is formed in the center of the upper female die, the female die guide sleeve is assembled in the through hole in an interference fit manner, an extruding opening assembling hole is formed in the lower female die, the extruding opening is assembled in the extruding opening assembling hole in an interference fit manner, and the female die guide sleeve and the inner hole of the extruding opening are correspondingly arranged. The rod extruding die structure can continue production only by replacing the extruding opening part after the rod extruding die is worn, and only the punch, the female die guide sleeve and the extruding opening are replaced when other products need to be replaced, so that the structure is simple and the design is ingenious; but also improves the utilization rate of the die and reduces the processing cost.

Description

Rod extruding die structure

Technical Field

The invention relates to a rod extruding die, in particular to a replaceable rod extruding die structure.

Background

At present, in the rod extruding process, the consumption of a mold is large; in particular to high-temperature alloy and titanium alloy products, the high hardness greatly abrades the rod-extruding die. And when the abrasion of the rod extruding die exceeds the required size, the rod extruding die needs to be discarded. Different products need to be manufactured into different rod extruding dies, and the defects of low die utilization rate and high processing cost exist.

Disclosure of Invention

The invention aims to provide a rod extruding die structure, which aims to solve the problems of low die utilization rate and high processing cost of a rod extruding die in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an crowded pole die structure, its includes crowded pole mould, drift and crowded pole mould bed die, the drift install in on the last mould of crowded pole mould, wherein, crowded pole mould bed die includes bed die, lower bed die, bed die guide pin bushing and extrusion mouth, down the bed die can be fixed in on the bottom surface of bed die with dismantling, the center department of going up the bed die has seted up the through-hole, bed die guide pin bushing interference fit assemble in the through-hole, be provided with extrusion mouth pilot hole down on the bed die, extrusion mouth interference fit assemble in the extrusion mouth pilot hole, the hole of bed die guide pin bushing and extrusion mouth corresponds the setting.

Particularly, the extrusion opening assembling hole is a tapered hole with a large upper part and a small lower part, and the outer wall corresponding to the extrusion opening is also of a tapered structure.

Particularly, the extrusion opening extends into the through hole to form a positioning section, and the positioning section abuts against the bottom end of the female die guide sleeve.

Particularly, the upper end of the extrusion opening is provided with a limiting step surface for limiting the positioning section.

Particularly, the upper female die and the lower female die are both of cylindrical structures, a plurality of notches are formed in the lower portion of the upper female die at intervals along the circumferential direction of the same height of the upper female die, a plurality of connecting holes are formed in the notches and the lower female die correspondingly, and the fixing bolts penetrate through the connecting holes to fix the lower female die on the upper female die.

Compared with the prior art, the invention has the advantages that the production can be continued only by replacing the extrusion opening part after the extrusion rod die is worn, and only the punch, the female die guide sleeve and the extrusion opening are replaced when other products need to be replaced, so that the structure is simple and the design is ingenious; but also improves the utilization rate of the die and reduces the processing cost.

Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, in the present embodiment, a rod-extruding die structure includes a rod-extruding die upper die 1, a punch 2, and a rod-extruding die female die 3, the rod-extruding die upper die 1 is provided with a punch mounting hole 4, a fixing screw penetrates through the punch mounting hole 4 to fix a top end of the punch 2 on a bottom surface of the rod-extruding die upper die 1, the rod-extruding die female die 3 includes an upper female die 30, a lower female die 31, a female die guide sleeve 32, and an extrusion opening 33, the upper female die 30 and the lower female die 31 are both of a cylindrical structure, a plurality of notches 34 are spaced apart from a lower portion of the upper female die 30 along a circumferential direction of the same height, a plurality of connection holes are provided in the notches 34 corresponding to the lower female die 31, and a fixing bolt penetrates through the connection holes to fix.

Go up female mould 30's center department and seted up through-hole 35, female mould guide pin bushing 32 interference fit assembles in through-hole 35, is provided with extrusion mouth pilot hole 36 on the female mould 31 down, and extrusion mouth pilot hole 36 is big-end-up's bell mouth, and the outer wall that corresponds extrusion mouth 33 also is the toper structure, and extrusion mouth 33 interference fit assembles in extrusion mouth pilot hole 36, and female mould guide pin bushing 32 corresponds the setting with the hole of extrusion mouth 33.

The extrusion opening 33 is provided with a positioning section 37 extending inwards the through hole, the positioning section 37 abuts against the bottom end of the female die guide sleeve 32, and the upper end of the extrusion opening 33 is provided with a limiting step surface 38 used for limiting the positioning section 37.

The female die of the extrusion rod die adopts a split structure design, after the extrusion rod die is worn, only the part of the extrusion port 33 needs to be replaced, and production can be continued, and when other products need to be replaced, the punch 2, the female die guide sleeve 32 and the extrusion port 33 only need to be replaced.
