SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an crowded pole mould structure to there is the low and high problem of processing cost of mould utilization ratio in the crowded pole mould of solution prior art.

To achieve the purpose, the utility model adopts the following technical proposal:

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.

The utility model has the advantages that compared with the prior art, the rod extruding mould structure can continue production only by replacing the extrusion port part after the rod extruding mould is worn, and only the punch, the female mould guide sleeve and the extrusion port are needed to be replaced when other products are needed, 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.
