A special-shaped ceramic brick forming mold and its preparation method

Abstract

The invention discloses a special-shaped ceramic tile forming mold and a manufacturing method thereof, and belongs to the technical field of powder forming. The special-shaped ceramic tile forming mold comprises a middle frame, wherein an inner cavity of which the cross section is quadrangular is formed in the middle frame; and corners of the quadrangular inner cavity are right-angled. The special-shaped ceramic tile forming mold is characterized in that angle blocks are arranged on corners of side walls of the inner cavity, and the angle blocks and the side walls of the inner cavity form a mold cavity jointly in a surrounding manner. The angle blocks are arranged in the middle frame which has the traditional structure, and the angle blocks and the side walls of the inner cavity form the mold cavity for special-shaped ceramic tiles jointly in the surrounding manner, so that the difficulty on machining of the special-shaped inner cavity of the middle frame in the prior art is reduced greatly; center lines of the side plate mounting holes are perpendicular to the side walls of the middle frames; the method is the same with the traditional method of machining side plate mounting holes, the technical is mature, and machining is facilitated; and moreover, the angle blocks which serve as small objects can be precisely manufactured by mature technologies of edge milling or linear cutting in the prior art, and the shape of the mold cavity is convenient to control.

Description

technical field [0001] The invention belongs to the technical field of powder molding, and in particular relates to a molding mold for special-shaped ceramic bricks and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people's demand for home decoration is also increasingly diversified. As an environmentally friendly building material, ceramic tiles have long been the first choice for home decoration. However, the vast majority of traditional ceramic tiles are square or rectangular, and their shapes are relatively single, which cannot meet the increasingly diverse needs of people. [0003] In order to broaden the market and enhance competitiveness, ceramic tile manufacturers have developed a regular hexagonal ceramic tile. Like the traditional ceramic tiles, the ceramics are formed by pressing ceramic powder in the cavity of the mold, and its shape and size are controlled by the cavity of the mold. The mold u...

Problems solved by technology

[0004] 1. The inner cavity of the traditional middle frame 1 is processed by an end mill on a gantry milling machine. To process the inner cavity into a regular hexagon, the middle frame 1 must be turned 60 degrees on the workbench, so that the middle frame 1 It will exceed the workbench and cannot pass through the gantry, and cannot be processed

[0005] 2. Since the included angle of each side wall of the regular hexagonal cavity is 120 degrees, it is difficult to achieve more accurate control, resulting in the formed ceramic tiles not being regular hexagonal, and the ceramic tiles cannot be closely connected, which affects the decorative effect and limits Popularization and application of regular hexagonal ceramic tiles

[0006] 3. This kind of mold requires that the center of the installation hole 2 of the side plate 3 forms an included angle of 60 degrees with the outer wall of the middle frame 1, or the center of the installation hole 2 of the side plate 3 forms an included angle of 60 degrees with the side wall, which is difficult to achieve precise control , affecting the installation angle of the side plate 3, greatly increasing the processing difficulty of the side plate installation hole 2
