Abstract

The utility model relates to a hard alloy mould for making ceramic floor and wall tiles, comprising a frame, a plurality of female moulds which are composed of a plurality of side plates and are fixed on the inner wall of the frame and side plates which are composed of hard alloy and steel base bodies for supporting the hard alloy, and the utility model also comprises hard alloy used for fixing shaping faces or compression faces of the side plates and ceramic ground and wall tiles. The utility model solves the problems of low hardness and short service life of ceramic ground and wall tiles which are made of alloy steel or high-speed tool steel. The utility model relates to a matched mould of ceramic shaping, particularly a ceramic shaping press.

Description

Carbide alloy pottery ground, wall brick mould

The utility model relates to forming process of ceramics, particularly with the supporting mould of forming process of ceramics forcing press.

At present, extensive use steel alloy (Cr12MoV) is made pottery ground, wall brick pressing mold both at home and abroad, because the hardness low (HRC58-60) of this kind steel alloy have only 12-15 service life round the clock, thereby more mold exchange is frequent, causes very big waste, production cost increases; 92208202 and 94,221,995 two utility model patents provide some improved new dies, their adopt and to inlay high-speed tool steel or to solve the low problem of steel alloy hardness in the method for mold periphery edge antifriction alloy, but can only improve life-span 2-3 doubly, effect is undesirable.

The purpose of this utility model is pottery ground, the wall brick mould that a kind of high life will be provided.

The utility model comprises a framework, a plurality of side plates are formed a plurality of formers, former is fixed on the inwall of framework, and side plate is made up of the steel matrix of carbide alloy and supporting carbide alloy, and forming face that contacts with pottery ground, wall brick on side plate or compression face be carbide alloy fixedly.

Because the utility model is to change side plate into carbide alloy with forming face or the compression face that pottery ground, wall brick contact, the life-span of its mould has improved more than 13 times; The time of a die change that brickmaking machine omits produces continuously, can increase production the ceramic tile that is worth more than 700,000 yuan, energy-conservation 80,000 yuan simultaneously, again because forming face or compression face are carbide alloy, the no scratch of product periphery that uses the utility model to make, even mould is during because of overproof scrapping, and the product periphery does not have scratch yet.

The utility model will be further described below in conjunction with accompanying drawing

Fig. 1: embodiment 1 structural representation

Fig. 2: A-A cutaway view Amplified image

Fig. 3, Fig. 4, Fig. 5, Fig. 6 are that carbide alloy is fixed on several forms on the steel matrix

Find out that from Fig. 1 and Fig. 2 present embodiment has a framework 1, a plurality of side plates 6 are formed a plurality of formers 5, and former 5 is fixed on the inwall of framework 1; Each side plate 6 is made up of the steel matrix 2 of carbide alloy 4 and supporting carbide alloy 4, its connected mode is varied, embodiment 1 be with screw 3 with the carbide alloy 4 of bulk be pressed on respectively the top of steel matrix 2 and below, Fig. 4 is that the carbide alloy 4 with bulk is embedded in the steel matrix 2, every block of side plate 6 all has carbide alloy 4 up and down like this, thereby form two cover formers 5 up and down, after top former 5 surpasses service life, all side plate 6 above-below directions are turned, just can use the former 5 of another side, reduce the time of making mould.Framework 1 is installed in the press base; Can use through debugging.

In order to save carbide alloy 4, only forming face or the compression face that contacts with pottery ground, wall brick at side plate 6 installed the carbide alloy 4 or coated with hard alloy 4 powder of sheet, also can reach above-mentioned same effect; Fig. 3, Fig. 5, Fig. 6 are fixed on connected modes such as the hot embedding of carbide alloy 4 usefulness of sheet, welding, dovetail on the steel matrix 2.

The carbide alloy that the utility model adopted is to make the hard phase with tungsten carbide; Nickel, chromium, molybdenum are made the bonding phase, and its fundamental component percentage by weight is as follows: tungsten carbide 80-94%, nickel 5-15%, chromium 0.3-3%, molybdenum 0.5-3%.This hardness of alloy reaches HRA88-89, and corrosion resistance strengthens greatly, is specially adapted to ceramic die.
