Abstract

Relate to the Cold Extruding Die device of mould, comprise clam member, die shrink ring, die plate insert, its die shrink ring is step, inside has retainer plate, and die plate insert is arranged at retainer plate bottom, and fastening briquetting is on the step of die shrink ring.The utility model can prevent the race material produced in extrusion process, and its extruding is beated stable, and axiality is good, and easy to maintenance, spare part difficulty of processing and cost low.

Description

Cold Extruding Die device

Technical field

The utility model relates to mould.

Background technology

Guide cylinder cold stamping die is split type die, and namely die set forms up and down, and advantage is that service life is longer, in the groove of its lower cavity die bottom upper cavity die, makes upper cavity die be close on lower cavity die, adopts the mode of positioning spigot to carry out radial location.In extrusion process, upper lower cavity die engages and does not tightly easily cause running material, and extrusion is beated and is difficult to ensure.And solid die is have an insert in die, advantage is that die axiality is guaranteed, but easily cracks at step R place and cause die to scrap.

Summary of the invention

The utility model is to provide: Cold Extruding Die device, and it is a kind of deficiency overcoming above-mentioned two kinds of dies, and has the concave die device of above-mentioned two kinds of die advantages.

The technical solution of the utility model is:

The utility model comprises clam member, die shrink ring, retainer plate, die plate insert, die shrink ring outside is step, inside there is a retainer plate, die shrink ring coordinates with retainer plate prestressing force, a die plate insert is arranged at the bottom of retainer plate, retainer plate and die plate insert interference fit, clam member is on the step on die shrink ring top.

The utility model has the advantages that:

1, the utility model can prevent the generation of running material phenomenon in extrusion process, and extruding is beated more stable than split type die, and is convenient to adjustment, long service life;

2, the utility model can ensure its axiality, easy to maintenance, and its die plate insert is changed quick, and difficulty of processing reduces, and cost reduces;

3, the easy installing/dismounting of insert, for Extruding die coating process provides condition.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Detailed description of the invention

See accompanying drawing embodiment, the utility model is described in further detail.

In Fig. 1: die shrink ring 2 is outer steps shape, inside there is a retainer plate 3, die shrink ring 2 coordinates with retainer plate 3 prestressing force, a die plate insert 4 is arranged at the bottom of retainer plate 3, interference fit between retainer plate 3 and die plate insert 4, clam member 1 is compressed fastening at the step place of die shrink ring 2

Its mould, through Long-Time Service, reaches the level of split type die its service life, and axiality is guaranteed and reaches the level of integral concave mould.
