Abstract
The utility model discloses a ceramics cylinder isostatic pressing inner diameter one-shot forming mould, which relates to a mould and comprises a forming mould sleeve and a core. The utility model is characterized in that the core is positioned in the forming mould sleeve through an upper rubber sealing head and a lower rubber sealing head; the core consists of an upper core and a lower core; the upper external diameter of the lower core is smaller than the lower external diameter and a conical surface is disposed at the external surface of the transition part of the core external diameter; the external diameter of the upper core is equal to that of the lower part of the lower core; the lower end of the upper core is connected to the upper end of the lower core and a core with a middle step structure is formed. The utility model is advantageous in that as the middle step structure can be directly formed into the middle inner step of the ceramic cylinder, thereby a processing on the inner diameter of a ceramic cylinder body is of no need; the problem that the working efficiency is low and cost is high can be solved; the one-shot forming mould is suitable for producing ceramic cylinder.
Description
Technical field
The utility model relates to mould, and specifically the pottery tube waits static pressure internal diameter one-shot forming mould.
Background technology
Before the utility model proposes, isostatic compaction technology is a kind of developing direction of vacuum ceramic moulding, is subjected to the favor of the ceramic tube of more and more vacuum interrupters manufacturer.The method of isostatic compaction explained hereafter vacuum arc-extinction porcelain tube is: will pack in the moulding rubber die by the powder of mist projection granulating, in cold isostatic press, be pressed into base just, with lathe first base car is made into base by drawing then, be fired into the pottery tube by high temperature kiln at last.But because the particularity of vacuum arc-extinction porcelain tube internal structure---middle interior step is less than porcelain spare two ends (as shown in Figure 3), cause the Vehicle Processing moulding is generally adopted in the processing of this special construction, that is: porcelain tube base substrate internal diameter when compacting stays certain Vehicle Processing surplus, after finishing the external diameter Vehicle Processing, change anchor clamps, go up lathe once more and press figure internal diameter machine-shaping.Do like this, though the core designs of mould is simple, handling ease, the internal diameter Vehicle Processing is taken a lot of work, the time-consuming material of expense again.
Summary of the invention
The purpose of this utility model will overcome the deficiencies in the prior art exactly, and a kind of simple in structure, time saving and energy saving and static pressure internal diameter one-shot forming mould such as pottery tube etc. of reducing production costs is provided.
At above-mentioned purpose, pottery tube provided by the utility model waits static pressure internal diameter one-shot forming mould, its technical scheme is: comprise moulding die sleeve and core, described core is positioned in the moulding die sleeve by last rubber end socket and following rubber end socket, described core comprises mo(u)ld top half core and following core, following core upper end external diameter is littler than lower end external diameter, and the outer surface of its external diameter intermediate location is a taper seat, the external diameter of last core is identical with the external diameter of following core lower end, the described core lower end of going up links to each other with following core upper end, form the core of band intermediate step structure, step in the centre of this intermediate step structure straight forming pottery tube in forming process, thus do not need once more the internal diameter of porcelain tube base substrate to be processed.
In such scheme, described core down upper end is provided with backstay, the position of last core correspondence is provided with the locating hole that matches with backstay, following core passes locating hole by backstay and is positioned at the mo(u)ld top half in-core, fix on the backstay and with nut, help core and following core like this location accurately is installed.
In such scheme, the described center of core down is provided with deep gouge, helps saving mold materials like this, thereby reduces cost.
In such scheme, described going up between core upper end and the nut is provided with sealing ring.
The combining structure that the utility model adopt to be gone up core and following core forms the core of band intermediate step structure, has guaranteed in the forming process step in the centre of straight forming pottery tube, thereby has not needed once more the inner surface of a ceramic base substrate to be processed.
The utility model is compared with the prior art, and shows that fully its superiority is: have simple in structure, time saving and energy saving and reduced the characteristics of production cost.
Description of drawings
Fig. 1 is a user mode structural representation view of the present utility model;
Fig. 2 is the user mode structural representation view of existing mold;
Fig. 3 is the structural representation view of pottery tube.
Among the figure: go up rubber end socket 1; Following rubber end socket 2; Moulding die sleeve 3; Core 4; Last core 4.1; Following core 4.2; Backstay 4.3; Deep gouge 4.4; Nut 5; Sealing ring 6; Powder 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, the utility model comprises moulding die sleeve 3, goes up core 4.1 and following core 4.2, it is described that core 4.2 upper end external diameters are littler than lower end external diameter down, and the outer surface of its external diameter intermediate location is a taper seat, the external diameter of last core 4.1 is identical with the external diameter of following core 4.2 lower ends, described core 4.1 lower ends of going up link to each other with following core 4.2 upper ends, form the core 4 of band intermediate step structure, and this core 4 is positioned in the moulding die sleeve 3 by last rubber end socket 1 and following rubber end socket 2.
Above-mentioned core 4.2 upper ends down are provided with backstay 4.3, the position of last core 4.1 correspondences is provided with the locating hole that matches with backstay 4.3, following core 4.2 passes locating hole by backstay 4.3 and is positioned in the core 4.1, backstay 4.3 upper ends are also fixing with nut 5, and the number of this backstay 4.3 can design according to actual needs.Certainly, also can adopt other locate mode between last core 4.1 and the following core 4.2.Described going up between core 4.1 upper ends and the nut 5 is provided with sealing ring 6.The described center of core 4.2 down is provided with the deep gouge 4.4 that is used for economical with materials.The described material of going up core 4.1 and following core 4.2 adopts the 45# steel, after designing requirement processing, quenches polishing, chromium plating.
The using method of the utility model in actual production is as follows:
1, rubber end socket 2 is enclosed within down core 4.2 lower ends down, moulding die sleeve 3 is enclosed within down on the rubber end socket 2 again, and tightens moulding die sleeve 3 with rubber band;
