Abstract
The utility model discloses a pre-forming mold of high-purity aluminum-oxide cakes and belongs to the field of forming mold equipment. The pre-forming mold comprises a cavity body (1) and a movable pressing column (2), and is characterized in that the movable pressing column (2) is a solid cylinder; the cavity body (1) is in a round-pipe shape with openings at the upper end and the lower end; the outer diameter of the movable pressing column (2) is in clearance fit with the inner diameter of the cavity body (1) and the movable pressing column (2) can be freely pulled. The pre-forming mold disclosed by the utility model has the advantages that aluminum-oxide powder is pre-pressed into cakes, so that certain strength is achieved and the deformation is not easy; and polytetrafluoroethylene or PP materials are adopted, so that the pollution to high-purity aluminum oxide is avoided and the quality of products is guaranteed.
Description
Technical field
High purity aluminium oxide biscuit preforming tool belongs to the mould apparatus field.
Background technology
If high purity aluminium oxide carries out pre-stamped cake type and the intensity that guarantees the later stage compacting in the process of biscuit moulding.Often with punching block aluminium oxide is carried out dry-pressing formedly in the prior art, inevitably can produce friction in the dry-pressing formed process of punching block and polluting, introduce iron tramp.The utility model adopts tetrafluoro or PP material to make, and has stopped the problem that high purity aluminium oxide that the mould in the biscuit forming process causes pollutes.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of mould that can avoid the friction of high purity aluminium oxide biscuit forming process to pollute is provided.
The technical scheme that its technical problem that solves the utility model adopts is: this high purity aluminium oxide biscuit preforming tool, comprise cavity, movable compression leg, it is characterized in that: described movable compression leg is solid cylinder, and described cavity is the up and down tubular type of the equal opening in two ends; Described movable compression leg external diameter and cavity internal diameter matched in clearance, and can in cavity, freely twitch.
Concrete, described cavity and movable compression leg adopt tetrafluoro or PP material to make.
Concrete, described movable compression leg diameter is than the little 0.5～1.0mm of cavity internal diameter.
Concrete, the barrel thickness of described cavity is 15～20mm.
The utility model high purity aluminium oxide biscuit preforming tool is the pre-stamped mould therefor of high purity aluminium oxide biscuit moulding.
The utility model high purity aluminium oxide biscuit preforming tool can manufacture and design according to the large freedom in minor affairs of required aluminium oxide biscuit the mould of different sizes.
Compared with prior art, the beneficial effect that high purity aluminium oxide biscuit preforming tool of the present utility model has is: the utility model is that alumina powder is pre-pressed into biscuit, make it have certain intensity, can after further cold isostatic compaction in not yielding, make the even aluminium oxide biscuit of shape.The utility model uses tetrafluoro or PP material to stop the pollution of mould to high purity aluminium oxide in addition, has guaranteed the quality of product.
Description of drawings
Fig. 1 is the utility model high purity aluminium oxide biscuit preforming tool profile.
Fig. 2 is the utility model high purity aluminium oxide biscuit preforming tool top view.
Wherein: 1, cavity 2, movable compression leg.
Fig. 1～2nd, the most preferred embodiment of the utility model high purity aluminium oxide biscuit preforming tool is described further below in conjunction with 1～2 pair of the utility model of accompanying drawing.
The specific embodiment
With reference to accompanying drawing 1～2: high purity aluminium oxide biscuit preforming tool, comprise cavity 1, movable compression leg 2, wherein movable compression leg 2 diameters are than the little 0.5～1.0mm of cavity 1 internal diameter, and cavity 1 and movable compression leg 2 all are tetrafluoro or PP material.Movable compression leg 2 is solid cylinder, and cavity 1 is the up and down tubular type of the equal opening in two ends.
When the utility model uses, in the plane with in the quantitative alumina powder jointed cavity 1 of packing into, more movable compression leg 2 is inserted cavity 1, after manpower applies certain pressure, change in the low pressure press and suppress, press is exerted pressure to movable compression leg, alumina powder jointed in the cavity 1 is subjected to molded, after suppressing, take out a whole set of mould, a whole set of mould is turned over, push movable compression leg 2 biscuit of forming is ejected, finally obtain the preformed biscuit.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
