Abstract

The utility model provides a wet-method molding die orifice which comprises multiple coils whose calibers gradually increase/decrease. Each coil is provided with a molding ring and an overlap ring, wherein the overlap ring is positioned at the bottom of the molding ring and integrated with the molding ring, edges of the molding ring and the overlap ring are arranged in an inclined manner, and the diameter of the overlap ring is lower than that of the molding ring. The multiple coils are successively cooperated and connected via the overlap rings and the molding rings to realize molding. The coils are made of steel, the surfaces of the multiple coils are plated with chrome and thus respectively wrapped in hard chrome protective layers, and the thickness of the hard chrome protective layers ranges from 0.5mm to 1.5mm. According to the problem, the problem in the prior art that product quality is influenced due to the fact that burrs exist at the inner surface of the molding die orifice and rust tends to appear after long time use.

Description

A kind of wet moulding die orifice

Technical field

The utility model relates to the equipment for the manufacture of processing electric power transport means, more specifically, relates to a kind of former of electroceramics device.

Background technology

While adopting wet moulding to generate electroceramics, need to use vacuum press pug mill, carry out the turning of extrusion modling recycling by moulding die orifice and modify finished product.Existing moulding die orifice adopts stainless steel to be used as the manufactured materials of moulding die orifice more, because the inner surface of described moulding die orifice need to keep smooth, in making a slip of the tongue journey, the existing shaping mould of use finds, there is burr in the inner surface of described moulding die orifice, and the time limit one also there will be rusty stain for a long time, thereby affect the quality of product.

Utility model content

In view of the above, the purpose of this utility model is to provide a kind of wet moulding die orifice, occurs rusty stain, thereby affect the problem of product quality for solving prior art because the inner surface of moulding die orifice exists burr and the time limit one length.

For achieving the above object and other relevant objects, the utility model provides following technical scheme:

A kind of moulding die orifice is provided, comprise that multiple bores are the coil of incremented/decremented, the folded circle that described coil comprises shaping ring and is positioned at described shaping ring bottom and is connected as a single entity with described shaping ring, described shaping ring becomes to be obliquely installed with the edge of folded connection circle and the diameter of described folded circle is less than the diameter of described shaping ring, and the coil that described multiple bores are incremented/decremented coordinates connection moulding successively by folded connection circle and shaping ring; Described coil is steel, and wherein said multiple bores are the surface of the coil of incremented/decremented and all do chromium plating processing, superscribes a hard chrome protective layer in the surface of described coil, and the thickness range of described hard chrome protective layer is at 0.5mm to 1.5mm.

Preferably, described folded circle connected for detachable connection with coordinating of shaping ring.

Preferably, the shaping ring that described multiple bore is the coil of incremented/decremented all becomes consistent equal with the height of folded connection circle.

As mentioned above, the utlity model has following beneficial effect: the situation that has burr or rusty stain by changing described moulding die orifice inner surface in the chrome faced mode of described coil, in addition, outside the materials such as relatively existing employing stainless steel, the utility model can adopt general steel and then carry out chromium plating processing, original lower of the one-tenth of this mode, therefore, the utility model has solved well in prior art and has occurred rusty stain because the inner surface of moulding die orifice exists burr and the time limit one is long, thereby affects the problem of product quality.

embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, all other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belong to the scope that the utility model is protected.

Please refer to Fig. 1 and Fig. 2, the surface-treated structural representation of a kind of wet moulding die orifice 11 that Fig. 1 provides in one embodiment for the utility model, the surface-treated broken section structural representation of the described a kind of wet moulding die orifice 11 providing in the specific embodiment exemplifying in Fig. 1 is provided Fig. 2, from figure, one shaped device 1 is provided in the present embodiment, moulding die orifice 11 on described shaped device 1, it comprises that multiple bores are the coil 2 of incremented/decremented, described coil 2 comprises shaping ring 21 and the folded circle 23 that is positioned at described shaping ring 21 bottoms and is connected as a single entity with described shaping ring 21, described shaping ring 21 becomes to be obliquely installed with the edge of folded connection circle 23 and the diameter of described folded circle 23 is less than the diameter of described shaping ring 21, the coil 2 that described multiple bore is incremented/decremented connects moulding by folded connection circle 23 and coordinating successively of shaping ring 21, described coil 2 is steel, and wherein said multiple bores are the surface of the coil 2 of incremented/decremented and all do chromium plating processing, superscribes a hard chrome protective layer 3 in the surface of described coil 2, and the thickness range of described hard chrome protective layer 3 is at 0.5mm to 1.5mm.

Particularly, described folded circle 23 coordinates connection for detachable connection with shaping ring 21, and the shaping ring 21 that described multiple bores are the coil 2 of incremented/decremented all becomes consistent equal with the height of folded connection circle 23.

In sum, there is the situation of burr or rusty stain by changing described moulding die orifice 11 inner surfaces in the chrome faced mode of described coil 2 in the utility model, in addition, outside the materials such as relatively existing employing stainless steel, the utility model can adopt general steel and then carry out chromium plating processing, original lower of the one-tenth of this mode, therefore, the utility model has solved well in prior art and has occurred rusty stain because the inner surface of moulding die orifice 11 exists burr and the time limit one is long, thereby affects the problem of product quality.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
