Abstract
The invention discloses a method for manufacturing a large-size earthenware slab, and relates to the technical field of ceramic part preparation. The method comprises the following steps of S1, mold design and manufacturing, wherein a needed workblank is designed according to the product specification, the workblank is a cube, the size specification section of the workbland is larger than 10,000 square millimeters, the height is 300 mm to 3,000 mm, an isostatic pressing mold is designed according to the workblank, the mold is composed of a square auxiliary mold body keeping a charging shape and a main mold body for bearing pressure, and the main mold body is composed of a square outer elastic mold sleeve, an elastic rubber end cap and a steel mold core. The method is low in equipment investment and low in mold manufacturing cost, large-specification and large-size products complex in shape can be produced conveniently, and the interiors of the products are even; and deformation and cracking are not prone to happen during sintering and grinding machining, and the method has great significance on manufacturing of large-size ceramic sintered parts.
Description
technical field [0001] The invention relates to the technical field of preparation of ceramic parts, in particular to a method for manufacturing a large-size ceramic flat plate. Background technique [0002] The preparation of high-tech ceramic products by spray-dried granulated powder dry pressing molding and isostatic pressing molding is mature and widely used, but for large-sized plate-shaped parts and arc-shaped parts (some with various grooves, holes, grooves, etc.) etc. The existing process has problems such as large equipment investment, difficult mold manufacturing, poor density uniformity, serious firing deformation, internal stress defects and cracks in processing, and many of these parts are used in high-precision or ultra-precision equipment or instruments, such as: Three coordinates, laser processing equipment, etc., the present invention solves the above problems, and is of great significance for the manufacture of large-sized ceramic fired parts.
