Abstract
The utility model discloses a hot-press sintering die with an inner lining and solves the problems that since dies in the prior art adopt integral structures, different dies are often required to be replaced for producing products with different specifications and sizes; the dies are inconvenient to dismantle; and once the interiors of the dies are slightly damaged, the whole dies are required to be replaced, and resources are wasted. The hot-press sintering die comprises a lower punch, an upper punch corresponding to the lower punch and an external die, wherein the external die is arranged on the external walls of the lower punch and the upper punch; and the inner lining, of which the external diameter is matched with the inner diameter of the external die, is arranged in the external die. When the hot-press sintering die with the inner lining is used for sintering, a user only need to put a filler into a filling area and then enables the filler to be subjected to hot-press sintering, and when the hot-press sintering are completed, the user only need to take the inner lining out but do not need to take the whole die out, so that the hot-press sintering die is convenient to mount and dismount, the trouble that a conventional die is needed to be wholly taken out after the sintering is completed is avoided; and meanwhile when the die is damaged, the user only need to replace the inner lining instead of the whole die, so that the manufacturing cost is greatly lowered.
Description
Technical field
The utility model relates to a kind of hot pressed sintering mould with liner.
Background technology
Hot pressed sintering is a kind of production technology that under HTHP pottery or metal dust is formed by a firing, and it adopts hot pressing die to carry out punch forming usually.Owing to be under the situation of very big pressure, to work, therefore general hot pressed sintering mould outer wall is all very thick, and general mould all is integrated now, often change different moulds for producing the different specification size product needed, the dismounting inconvenience is if mould inside has damage, need integral replacing, the waste resource, therefore, existing hot pressed sintering mould can not satisfy people's demand.
The utility model content
The purpose of this utility model is to provide a kind of hot pressed sintering mould with liner, mould all is structure as a whole in the solution prior art, often change different moulds to producing the different specification size product needed, dismounting is inconvenient, and mould inside has damage slightly, just need integral replacing, the waste problem of resource.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of hot pressed sintering mould with liner comprises low punch, with corresponding with it upper punch, and the external mold that is arranged at low punch and upper punch outer wall; Also be provided with the liner that external diameter and this external mold internal diameter are complementary on the described external mold inwall.
Further, the height of described liner is higher than the height 1cm of external mold at least.
Again further, described upper punch and low punch are cylinder.
In addition, described external mold and liner are cylindric.
As a kind of preferred, described external mold and liner are made by graphite.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is provided with liner in external mold, during sintering, only need filler is joined in the liner, after hot pressing is finished, only need the liner taking-up is got final product, do not need entire die is all taken out easy accessibility, the trouble of having avoided existing mould after sintering is finished, entire die must be taken out, simultaneously when mould has damage, only needing does not need to change entire die according to actual conditions changeable liner more, has reduced production cost widely.
(2) height of the utility model liner is higher than the height of external mold, when its role is to SINTERING PRODUCTION, can make things convenient for installation and the taking-up of mould, and the internal diameter of the external diameter of liner and external mold is complementary, pressure is excessive to ftracture liner because bearing when avoiding hot pressed sintering.
(3) external mold in the utility model and liner are made by graphite material, and it is strong to have an anti-pressure ability, and resistant to elevated temperatures characteristics, and it is very suitable for being applied in the vacuum heating-press sintering field.
(4) the utility model is simple in structure, and is easy to operate, safe and reliable, with low cost, is suitable for promoting the use of.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the parts name of mark correspondence is called in the accompanying drawing:
The 1-low punch, 2-upper punch, 3-external mold, 4-liner, 5-packing area.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, a kind of hot pressed sintering mould with liner comprises low punch 1, with corresponding with it upper punch 2, and the external mold 3 that is arranged at low punch and upper punch outer wall; Also be provided with the liner 4 that external diameter and this external mold internal diameter are complementary on the described external mold inwall.When being arranged on sintering like this, only need filler is joined packing area 5, after hot pressing is finished, only need the liner taking-up is got final product, do not need entire die is all taken out, easy accessibility, the trouble of having avoided existing mould after sintering is finished, entire die must be taken out, simultaneously when mould has damage, only need are according to actual conditions changeable liner more, do not need to change entire die, reduced production cost widely; And because the external diameter of liner and the internal diameter of external mold be complementary, thereby avoided when hot pressed sintering liner because bearing the excessive phenomenon generation of ftractureing of pressure.
For when the SINTERING PRODUCTION, can make things convenient for installation and the taking-up of mould, the height of described liner is higher than the height 1cm of external mold at least.
In order better to realize the utility model, described upper punch and low punch are cylinder; Described external mold and liner are cylindric.
In order to guarantee that anti-pressure ability of the present utility model is strong and high temperature resistant, described external mold and liner are made by graphite.
The course of work of the present utility model is as follows:
Before hot pressed sintering, at first liner is placed already installed external mold, then filler is joined in the packing area, by upper punch and low punch it is exerted pressure, after hot pressing is finished, directly liner is taken out, product is just along with liner is removed together, at last liner is separated with product, namely finish whole hot pressed sintering work.
The utility model is simple in structure, and is easy to operate, safe and reliable, with low cost, is suitable for promoting the use of.
According to above-described embodiment, just can realize the utility model well.What deserves to be explained is; under the prerequisite based on the said structure design; for solving same technical problem; some do not have substantial change or polishing even in that the utility model is made; the essence of the technical scheme that adopts is still the same with the utility model, so it also should be in protection domain of the present utility model.
