Problems solved by technology

Although the use of cemented carbide can improve the wear resistance of the mold working surface, but due to the extremely expensive price of cemented carbide, it is difficult to process and the production cost is high
Moreover, cemented carbide is very easy to crack during processing and is easy to be scrapped.

Embodiment Construction

[0012] Such as figure 1 As shown, the refractory brick / ceramic tile mold of the present invention with replaceable working surface includes a mold body 1, and the opposite sides of one side of the mold body 1 are all processed with ribs 4, and the mold body 1 between the two ribs 4 is processed on this surface. There are three grooves, and permanent magnets 2 are installed in the three grooves. A liner 3 used as a mold working surface is arranged between the two ribs 4, the thickness of the liner 3 is consistent with the height of the rib 4, and the inner surface of the liner 3 is pasted by a permanent magnet 2. Close on the face of the mold body 1 between the two sides 4 . Lining plate 3 wherein is to form with punching out of thin steel plate. When assembling, install the permanent magnets 2 one by one in the groove of the mold body 1, and then push the liner 3 from the side of the mold body 1 without ribs 4, and the permanent magnet 2 will suck the liner 3 and tighten it ...

Abstract

The invention relates to a working face-replaceable refractory brick / tile mould. The working face-replaceable refractory brick / tile mould comprises a mould body and is characterized in that the opposite two sides of one side surface of the mould body are provided with flanges, the surface of the mould body between the two flanges is provided with pits or slots, and permanent magnets are mounted inside the pits or slots; a lining plate serving as a mould working face is arranged between the two flanges, and the inner surface of the lining plate is adhered to the surface of the mould body between the two flanges through the permanent magnets. According to the working face-replaceable refractory brick / tile mould, the mould body is wearing-resistant, easy to machine, low in manufacturing cost, replacement-free, long in service life and particularly applicable to refractory brick / tile moulds.

Description

technical field [0001] The invention relates to a mold. Specifically, it is a mold that can be replaced on the working surface, especially suitable for refractory brick / tile molds. Background technique [0002] At present, in the refractory brick and ceramic tile production industry, most of the refractory brick molds or ceramic tile molds used are ground from bearing steel after carburizing and quenching. Due to the high hardness components such as quartz sand and silicon carbide in the raw materials of refractory bricks and ceramic tiles, the surface of the mold that is in contact with the adobe is subject to strong plowing and wear during the extrusion process of the adobe, which is easily damaged, resulting in a short life of the mold , Even multiple molds need to be replaced within one working shift. The replaced damaged mold needs to be re-grinded or re-quenched and re-grinded. It will be scrapped after multiple grindings. Big. In order to overcome this defect, som...
