Abstract

The utility model provides a grouting device which comprises an upper die and a lower die, wherein a die frame is arranged between the upper die and the lower die; a filter membrane is arranged between the inner surface of the upper die and the upper surface of the die frame; a filter membrane is also arranged between the inner surface of the lower die and the lower surface of the die frame; and a cavity is arranged in the die frame. The grouting device solves the technical problem of low yield in the die forming process and has no pollution to the formed product by adopting the resin materials. The compression strength of the resin materials is high and can bear greater grouting pressure, so that the formed product has high density, and the forming efficiency is also improved. The filter membranes are arranged in the die with the structure, so that micropores on the surfaces of the upper and lower dies cannot be easily blocked in the forming process, and the die ejecting is facilitated at the same time.

Description

A kind of grouting device

Technical field

The utility model relates to preparation ceramic target mold for forming, is specifically related to a kind of grouting device.

Background technology

Existing ceramic target mold for forming is made up of two moulds of negative and positive, according to the difference of shape of product, the groove identical with the shape of product curved surface is set in former or formpiston.Behind the matched moulds, slurry is injected under certain pressure in the cavity, after keeping the regular hour under certain pressure, form required product again.

And this kind mould adopts the gypsum material to make, polluted product, and compression strength is low, is not suitable for using the slip casing by pressure moulding, and practical number of times is less, and the demoulding is difficulty comparatively, makes the product of moulding easy to crack, and distortion, directly has influence on the yield rate of product.

Summary of the invention

In order to solve the low technical problem of yield rate in the above-mentioned ceramic target slip casing by pressure forming process, the utility model provides a kind of grouting device.

The grouting device that the utility model provides comprises patrix, counterdie is provided with framedly between the described upper die and lower die, be provided with the filtration mould between patrix inner surface and the framed upper surface, be provided with the filtration mould between counterdie inner surface and the framed lower surface, be provided with cavity in framed; Described framed injected hole and the plasma discharge hole of being provided with; Described cavity be shaped as one or more.

As further improvement in the technical proposal, the aperture of described filtration mould and filtration mould is 0.1 μ m or 0.8 μ m or 1.5 μ m.

As further improvement in the technical proposal, described upper die and lower die are made for the porous plastics material; Described filtration mould and filtration mould are the organic polymer material.

The utlity model has following advantage:

1, adopt resin material that the product of want moulding is not had any pollution;

2, the compressive resistance height of resin material can bear bigger grouting pressure, makes the product density height of formation, also the shaping efficiency of Ti Gaoing.

3, the filter membrane that is provided with in this knot mould makes product be not easy to stop up the micropore on upper and lower mould surface in forming process, also helps the demoulding simultaneously.

Description of reference numerals

Patrix 1, patrix inner surface 101; Counterdie 2, counterdie inner surface 201; Framed 3, framed upper surface 301, framed lower surface 302; Cavity 305, injected hole 303, plasma discharge hole 304; Filter mould 4; Filter mould 5.

The specific embodiment

Referring to shown in Figure 1,

The grouting device that the utility model provides comprises patrix 1, counterdie 2, and be arranged at framed 3 between patrix 1 and the counterdie 2, in order to prevent that product slip in forming process from stopping up the micropore on upper and lower mould surface, also help the demoulding, between patrix inner surface 101 and framed upper surface 301, be provided with and filter mould 4, be provided with filtration mould 5 between counterdie inner surface 201 and the framed lower surface 302, also be provided with cavity 305 in framed 3; This cavity 305 be shaped as one or more, the shape of product of the shape of cavity 305 and the moulding of wanting is consistent.For charging and plasma discharge, framed 3 are provided with injected hole 303 and plasma discharge hole 304; Patrix 1 and counterdie 2 adopt porous plastics to make, this porous plastics is made up of acrylic resin or epoxy resin, such material can bear big grouting pressure in the formed product process, owing to select for use resin material in forming process, not have in the product that foreign ion enters the moulding of wanting, in the quality that guarantees product simultaneously, also effectively raise yield rate.

Filtering mould 4 and filtering mould 5 is the organic polymer material, and this organic polymer material is polytetrafluoroethylene (PTFE) or polyether sulfone or nylon 6 or nylon 66 or mixed cellulose ester or polyvinylidene fluoride.Filtering mould 4 and filtering mould 5 its apertures is 0,01-20 μ m, thus reach good drainage effect, be convenient to after the use clean, can repeatedly use, also greatly reduce production cost; In order to adapt to the slurry of different performance, the aperture of filtering on mould 4 and the filtration mould 5 can be elected 0.01-0.5 μ m as; 0.5-1 μ m; 1-5 μ m; 5-10 μ m; Any interval value among the 10-20 μ m.Be preferably 0.1 μ m, 0.5 μ m or 1 μ m.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
