Abstract

The utility model discloses a double-guide die, which comprises an upper die and a lower die. An upper die assembly ring is fixedly sleeved on the outside of the upper die, a lower die assembly ring is sleeved on the outside of the lower die, the upper die and the lower die are assembled to form a die cavity, a guide cavity is disposed on the lower portion of the upper die assembly ring, a seam allowance is arranged on the outer edge of a die chamber of the lower die, after the upper die and the lower die are assembled, the lower die assembly ring extends into the guide cavity of the upper die assembly ring, and the upper die extends into the seam allowance of the lower die. The double-guide die realizes bidirectional guide, accordingly can reliably guarantee concentricity of the upper die and the lower die, improves position degree of products, and has the advantages of low cost, simple structure, fine reliability and the like.

Description

A kind of two guiding mould
Technical field
The utility model relates to a kind of mould, especially relates to the two guiding moulds that use in a kind of Forging Technology.
Background technology
Mould is to be used for the instrument of formed article, and this instrument is made up of various parts, and different dies is made up of different parts.It mainly realizes the processing of article profile through the change of institute's moulding material physical state.Existing mould adopts single guiding more; Promptly outside last, be installed with the matched moulds circle, be with matched moulds circle down outside on counterdie, lead to realize forging through last matched moulds circle and following matched moulds circle and process at patrix; The upper and lower mould axiality can be poor when but this kind mould forged; And the upper and lower mould axiality is the key factor that influences the product space degree, thereby has solved forging upper and lower mould axiality, is exactly to have solved a product space degree difficult problem to a great extent.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of simple in structure, two guiding moulds that the product precision is high.
The technical scheme of the utility model is following: a kind of two guiding moulds; Comprise upper die and lower die, be installed with the matched moulds circle outside on said patrix, be with matched moulds circle down outside on said counterdie; Said upper die and lower die matched moulds forms die cavity; Its main points are: matched moulds circle bottom is provided with the guiding cavity on said, has seam at the impression outward flange of said counterdie, behind the upper die and lower die matched moulds; Said matched moulds circle down stretches in the guiding cavity of said upward matched moulds circle, and said patrix stretches in the seam of said counterdie.Adopt above structure; During the upper die and lower die matched moulds, said down matched moulds circle stretches in the said guiding cavity of going up the matched moulds circle, thus realize upper guide to; The cavity that promptly leads can be realized down the thick guiding of matched moulds circle; Said patrix stretches in the seam of said counterdie, thus realize lower guide to, seam can be realized the essence guiding to patrix; Above two-way guiding can make the axiality of the upper die and lower die when forging high, so can be good at guaranteeing the position degree of product.
Gap M≤the 0.02mm of the madial wall of said patrix lateral wall and said seam, the gap N of said matched moulds circle lateral wall down and said guiding cavity madial wall is 0.08~0.12mm, adopts above structure, can guarantee guiding accuracy reliably.
Beneficial effect: the utility model adopts two-way guiding, thereby can guarantee the axiality of upper die and lower die reliably, so improved the position degree of product; Have characteristics such as cost is low, simple in structure, good reliability.
Description of drawings
Fig. 1 is the structure intention of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1: a kind of two guiding moulds; Comprise patrix 1 and counterdie 2, be installed with matched moulds circle 3 outward on said patrix 1, be with time matched moulds circle 4 outside on said counterdie 2; Said patrix 1 forms die cavity 5 with counterdie 2 matched moulds; Matched moulds circle 3 bottoms are provided with guiding cavity 3a on said, have seam 2a at the impression outward flange of said counterdie 2, behind patrix 1 and counterdie 2 matched moulds; Said matched moulds circle 4 down stretches in the guiding cavity 3a of said upward matched moulds circle 3, and said patrix 1 stretches in the seam 2a of said counterdie 2.
In Fig. 1, it can also be seen that: the gap M≤0.02mm of the madial wall of said patrix 1 lateral wall and said seam 2a, the gap N of said matched moulds circle 4 lateral walls down and said guiding cavity 3a madial wall is 0.08~0.12mm.
The above is merely the preferred embodiment of the utility model; It is not restriction with the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
