Abstract

The utility model discloses a forming die for the back side pattern of a ceramic brick, which relates to a ceramic forming die used for venting. The utility model comprises a die body, an upper surface of the die body and a back side pattern surface opposite to the upper surface of the die body, wherein back side pattern modules are distributed on the back side pattern surface of the die body. The utility model is characterized in that venting convex blocks are fixed to the back side pattern surface, and through holes are arranged on the venting convex blocks and communicated with the upper surface of the die body. Because the venting convex blocks are fixed to the back side pattern surface of the die body, and the venting through holes are arranged on the convex blocks and communicated with the upper surface of the die body, the gas in the ceramic powder material can be smoothly discharged through the venting through holes when the forming ceramic brick is pressed, which improves the density uniformity of the ceramic body and enhances the quality of the ceramic brick body. In addition, the back side pattern surface of the ceramic brick can not generate projection. The utility model can be applied to ceramic plants to produce floor bricks or fields in others trades that make use of powder material to press forming plate-shaped components.

Description

Ceramic Tiles back of the body line mould

Technical field

The utility model belongs to the forming process of ceramics mould applications, is specifically related to a kind of forming process of ceramics mould that is used for exhaust.

Background technology

The upper and lower surface of ceramic floor brick is generally burnishing surface and back of the body line face, and burnishing surface when laying, is carried on the back line face and ground firm attachment through polishing rear surface good quality.Building ceramics factory when producing the ceramic wafer brick, adopt press and mould with ceramic powder press-formed be Ceramic Tiles.Contain a large amount of air in the powder in the mould of being made up of upper mold core and lower mold core, the air in pressing process in the ceramic powder must overflow.Otherwise the density of the Ceramic Tiles after the moulding is inconsistent, makes the Ceramic Tiles base substrate break easily in follow-up polishing, polishing process.In the prior art situation, the mould that building ceramics factory uses air when producing the plate brick can only be discharged from the slit between core rod and the mold periphery.For small-sized mould, the exhaust resistance during moulding is less relatively, and exhaust is also more smooth and easy.But be of a size of 60 * 60cm or above Ceramic Tiles mould for production, the resistance during exhaust is very big, and the time of exhaust is also very long.Be exhaust from powder smoothly, can realize by the shaping speed that reduces press, but simultaneously also with low production efficiency.For addressing these problems, people have offered a lot of through holes on mould, and in the compression moulding process of Ceramic Tiles base substrate, a large amount of gases in the powder can be discharged from these through holes.But because gas can drive a small amount of powder overflow when discharging from these through holes in the back of the body line face formation point-like of Ceramic Tiles, the projection of wire.The existence of these projectioies can cause the Ceramic Tiles injustice that lands.Because the existence of above-mentioned drawback, a lot of building ceramics factories are in the operation of compression moulding Ceramic Tiles or reduce press-molding speed obtaining balanced good exhaust performance, or simply do not make independent pump-down process.Above-mentioned measure has reduced production efficiency, has also reduced product quality.

The utility model content

For overcoming the deficiencies in the prior art part, the utility model provides a kind of Ceramic Tiles back of the body line mould, and this mould has been realized good exhaust performance and the Ceramic Tiles back of the body line face produced does not have projection in the process of compression moulding Ceramic Tiles.

The scheme that its technical problem that solves the utility model adopts is: design a kind of Ceramic Tiles back of the body line mould, comprise die ontology, the upper surface of die ontology, and the back of the body line face relative with the die ontology upper surface, back of the body line module distributes on the back of the body line face of die ontology, it is characterized in that on back of the body line face fixedly exhaust projection, offer through hole on the exhaust projection, this exhaust hole is connected with the upper surface of die ontology.

The exhaust projection is a long strip type, and the exhaust projection is determinant and is distributed on the back of the body line face; Back of the body line module is determinant arranges and is arranged on the back of the body line face, and the exhaust projection is arranged between the two adjacent back of the body line module ranks; The height of exhaust projection can be set to 0.5-1mm.

The beneficial effect that the utility model had is:

Since on the back of the body line face of die ontology fixing exhaust projection, offered the exhaust hole that is connected with the die ontology upper surface on the projection, when the compression moulding Ceramic Tiles, gas in the ceramic powder can smooth and easy discharge in exhaust hole, improve the ceramic body density uniformity, improved the quality of Ceramic Tiles base substrate.

2. during compression moulding Ceramic Tiles, the gas in the powder discharges and drives a small amount of powder overflow, and the powder raised line of overflow has been limited in the rectangular groove on the Ceramic Tiles, thereby makes the back of the body line face of Ceramic Tiles can not produce projection.

3. the utility model can be used building ceramics factory and produce floor tile, or other industry is utilized the field of powder compression moulding tabular component.

The specific embodiment

As shown in Figure 1, 2, be distributed with a plurality of back of the body line modules 2 on the back of the body line face 111 of die ontology 1, back of the body line module is used for the shrinkage pool on the press ceramic brick back of the body line face, and back of the body line module 2 is the determinant setting.Fixed exhaust projection 3 between two adjacent back of the body line module ranks, offered exhaust hole 4 on the exhaust projection 3, this exhaust hole is connected with die ontology upper surface 112.

Shown in Fig. 3,4, die ontology 1 and the lower mold core 5 compression moulding Ceramic Tiles that is involutory, the gas in the powder is smooth and easy discharge from exhaust hole 4, has improved the density uniformity of Ceramic Tiles.Among Fig. 4, on the surface of Ceramic Tiles body 7, form and exhaust projection 3 corresponding recesses 9.When the gas in the powder is discharged, can form fin 6 on the Ceramic Tiles body 7 from exhaust hole 4.Owing to the existence that recess 9 is arranged makes fin 6 be positioned under the recess 9, thereby fin 6 is lower than the back of the body line face 111 of Ceramic Tiles body 7.This makes the good stability that lands when laying Ceramic Tiles.

When making die ontology 1, the height that can control exhaust projection 3 is 0.5-1mm, and promptly the degree of depth of the recess 9 on the Ceramic Tiles body 7 after the compression moulding is 0.5-1mm.Best results in such cases.
