Abstract
The utility model relates to an isostatic mould-core for producing ceramic tile moulds. An oil recess plate is embedded in an upper mould plate; a sealing rubber layer is covered between the surface of the oil recess plate and a working face rubber layer, and the back side of the sealing rubber layer is provided with a convex pressure transmission piece at the position corresponding to an oil recess; the side periphery of the oil recess plate, which is connected with the upper mould plate, is provided with gaps and sealing grooves; rubber filled in the gaps and the sealing grooves is connected with the working face rubber layer or the sealing rubber layer into integration. The isostatic mould-core can completely block all channels leading to the working face, can ensure no oil leakage, improves the service life of moulds, and ensures the quality of green bricks.
Description
The utility model relates to the core rod of the core rod of producing mould for ceramic wall and floor tiles, particularly a kind of isostatic tooling.
During the adobe of compacting ceramic tile, because powder fills not really evenly in die cavity, it is also inhomogeneous that the difference of each dot density makes it the blank density of compression moulding, the ceramic tile dimension low precision after firing, and yield rate is on the low side.Existing import mould in core rod, be provided with a plurality of pressure transmission parts of HYDRAULIC CONTROL SYSTEM with equalization of pressure pass to downtrodden adobe.Use this isostatic tooling that the quality percentage of product is improved greatly.Chinese patent 95205523.6 has also provided one " isostatic mold core ", and it establishes a plurality of oil grooves that communicate in cope match-plate pattern, is provided with the pressure transmission part between each oil groove and the rubber layer as working face, so that oil pressure is passed to adobe by a plurality of pressure transmission parts.Because the pressure transmission part is to fill in the concave station of template, in the course of work of exerting pressure, the concave station of the relative template of pressure transmission part has micro displacement, and promptly the fit clearance place of pressure transmission part and template concave station may leakage of oil.The service life of in fact this isostatic mold core is often unsatisfactory, and main cause is exactly leakage of oil.Hydraulic oil leaks under the rubber layer as working face.May cause that working face rubber layer and template peel off, even may break through rubber layer because of oil pressure is excessive.The most recurrent then is that fluid oozes out from the rubber layer edge, pollutes the working face of die cavity and influences downtrodden unfired brick quality.
The purpose of the utility model is to provide a kind of isostatic mold core that prevents that hydraulic oil from oozing out, and to improve the service life of mould, guarantees unfired brick quality.
Isostatic mold core described in the utility model, the oil groove that is interconnected is arranged in the cope match-plate pattern, cope match-plate pattern surface coverage working face rubber layer, embed an oil pocket plate in the cope match-plate pattern, have a plurality of oil pockets that communicate with oil groove on the oil pocket plate, there is the pressure transmission part that protrudes into oil pocket at the corresponding oil pocket place at the oil pocket plate surface coverage caulking gum layer and the caulking gum layer back side, the side perimeters that oil pocket plate and cope match-plate pattern join has the narrow end communication seals groove in slit wide outside and narrow inside and slit, and rubber of filling in slit and the seal groove and working face rubber layer or caulking gum layer are connected as a single entity.
Described isostatic mold core, between working face is with glue-line and oil pocket plate, cover the caulking gum layer that one deck and pressure transmission part are connected as a single entity again, and equal filled rubber in peripheral slit that the oil pocket plate links to each other with cope match-plate pattern and the seal groove, hydraulic oil all passages have been blocked fully towards working face, can guarantee oil-proof, thereby improved service life, and guaranteed unfired brick quality.
The upward view of Fig. 1 cope match-plate pattern;
Fig. 2 is the A-A partial enlarged drawing of Fig. 1;
Fig. 3 is the A-A partial enlarged drawing of Fig. 1.
Embodiment is just like Fig. 1,2
Embed oil pocket plate 5 in the cope match-plate pattern 1, have a plurality of oil pockets 8 on the oil pocket plate, oil groove 7 in the cope match-plate pattern is communicated with each oil pocket 8, oil pocket plate 5 surface coverage caulking gum layers 3, there is the pressure transmission part 4 that protrudes into oil pocket at corresponding each oil pocket 8 place, the caulking gum layer back side, by a plurality of bolts 6 oil pocket plate 5 and caulking gum layer 3 are fixed on the cope match-plate pattern 1.Oil pocket plate 5 has slit wide at the top and narrow at the bottom 10 with the periphery that cope match-plate pattern 1 joins, slit narrow end communication seals groove 9, and rubber of filling in slit and the seal groove and working face rubber layer 2 are connected as a single entity.
Embodiment two is as Fig. 3
The rubber and the caulking gum layer 3 of filling in slit 10 and the seal groove 9 are connected as a single entity, and all the other are identical with embodiment one.
Claims (1)
