Abstract

The utility model discloses a six composite mold structures, include: mold core, center circle and mould shell, the quantity of mold core is six, and these six mold cores enclose and establish into a composite mold structure, the outer lane of composite mold structure is circular, the center circle sets up in the periphery of composite mold structure, and is interference fit between center circle and the composite mold structure, a hole has been seted up in the mould shell, center circle set up in in the hole, be interference fit between the hole of center circle and mould shell. In this way, the utility model discloses six angles can solving the hexagonal mould receive the problem that stress rises easily and split, have improved the hexagonal mould utility life -span.

Description

A kind of six combination die structures

Technical field

This utility model relates to mould applications, particularly relates to a kind of six combination die structures。

Background technology

Hexagonal flange screw is a kind of common securing member, when producing hexagonal flange screw, hexagonal flange needs to produce with mould, and produce hexagonal flange screw, during whole hexagonal, owing to stress is too big, existing six angles of hexagonal mould place is due to by stress effect, easily it is split up, reduces the service life of hexagonal die life, add the cost payout of enterprise simultaneously。

Utility model content

This utility model is mainly solving the technical problems that provide a kind of six combination die structures, it is possible to solves the problem that six angles of hexagonal mould are easily split up by stress, improves the hexagonal mold use life-span。

For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of six combination die structures, including: core rod, central ring and formwork, the quantity of described core rod is six, and these six core rods enclose and are set as a combination die structure, the outer ring of described combination die structure is circular, described central ring is arranged at the periphery of combination die structure, and be interference fit between central ring and combination die structure, an endoporus is offered in described formwork, described central ring is arranged in described endoporus, is interference fit between described central ring and the endoporus of formwork。

Preferably, wherein the structure of every core rod is all identical with size。

Preferably, the outer ring radian of described core rod is 60 °。

The beneficial effects of the utility model are: hexagonal mode division is become six by this utility model, then combines with central ring, and by interference fit, such stress is released, and the life-span of hexagonal mould improves tens times。

In accompanying drawing, the labelling of each parts is as follows: 1, six core rods, and 2, central ring, 3, formwork。

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining。

Referring to Fig. 1 to Fig. 5, this utility model embodiment includes:

A kind of six combination die structures, including: core rod 1, central ring 2 and formwork 3, the quantity of described core rod 1 is six, and these six core rods 1 enclose and are set as a combination die structure, the outer ring of described combination die structure is circular, and described central ring 2 is arranged at the periphery of combination die structure, and be interference fit between central ring 2 and combination die structure, offering an endoporus in described formwork 3, described central ring 2 is arranged in described endoporus, is interference fit between described central ring 2 and the endoporus of formwork 3。

When this utility model is installed, six core rod 1 interference fit being first pressed into central ring 2, then together with central ring 2 interference fit, six core rods 1 being press-fitted are pressed into formwork 3, by this kind of structure, stress is released, and the life-span improves tens times。

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model。
