Manufacture method of ceramic die blank

Abstract

The invention discloses a manufacture method of a ceramic die blank. The manufacture method of the ceramic die blank comprises the following steps: building a three-dimensional model of a die blank; slicing the three-dimensional model of the die blank to manufacture a plurality of two-dimensional slice models; smelting the selected material, stacking to manufacture the three-dimensional model of the die blank layer by layer according to outline information of multilayer two-dimensional slice models of the three-dimensional model of the die blank to obtain a die blank entity; and carrying out surface treatment on the die blank entity. The method is capable of directly forming a complex three-dimensional die blank; the problems of molding and production of dies are solved; all the parts are relatively good in connection properties and high in surface smoothness; the functions of the die blank can be better realized. In addition, the manufacture method is high in flexibility degree; the labor intensity of artificial carving is alleviated; the product is short in development period and high in machining speed.

Description

technical field [0001] The invention relates to the field of processing technology, in particular to a method for making a ceramic mold. Background technique [0002] In the production process of traditional ceramics, grouting is usually used. Based on the physical characteristics of the gypsum mold that can absorb water, the ceramic powder ingredients are formulated into a fluid slurry, and then injected into the mold. After the water is absorbed by the mold, The ceramic mud forms a uniform mud layer with a certain thickness, and the green body with a certain strength is formed during the dehydration and drying process. [0003] However, before this, it is necessary to manually make ceramic molds. The production process includes determining the production drawing, material selection, rough carving and fine carving, etc. In order to ensure that the target ceramic parts can be made, this process requires a lot of labor and time. High strength and long production cycle. For ...

[0003] However, before this, it is necessary to manually make ceramic molds. The production process includes determining the production drawing, material selection, rough carving and fine carving, etc. In order to ensure that the target ceramic parts can be made, this process requires a lot of labor and time. High strength, long production cycle

For some target parts with complex structures, the mold making process is more complicated and time-consuming, and there are even many processed parts that cannot be made through molds, so the scope of use of molds is limited

In addition, molds are used to shape ceramics. The quality of molds and the flatness of the surface of molds seriously affect the production process and effect of ceramics.
