Casting device for manufacturing fused silica ceramics

Abstract

The invention discloses a casting device for manufacturing fused silica ceramics. The casting device comprises a filtering net, a variable-speed motor, a centrifugal cavity, a constant temperature layer and auger blades. The constant temperature layer is installed inside the centrifugal cavity, the constant temperature layer is internally provided with the auger blades, the variable-speed motor ismounted on the lower part of the left side of the centrifugal cavity, and the filtering net is installed on the upper part of the left side of the variable speed motor. The casting device is scientific and reasonable in structure and safe and convenient to use, the filtering net can filter impurities doped into the mud, and the quality of quartz sand ceramic handicrafts is improved; the variable-speed motor is arranged to limit the rotation speed of the auger blades to control the inflow speed of the mud by adjusting the rotation speed of the motor; the centrifugal cavity can enable the mud to perform centrifugation to enable the mud to be stirred more uniformly and thoroughly, and the hardness of the quartz sand ceramic handicrafts is enabled to be higher; and the constant temperature layer is arranged to enable the mud to be not affected by the temperature in the centrifugal cavity.

Description

technical field [0001] The invention relates to the technical field of casting devices, in particular to a casting device for making fused silica ceramics. Background technique [0002] At present, the commonly used quartz ceramic molding process is mud casting. Due to the incomplete mixing of the mud, the microstructure is uneven, the reliability of the material is poor, the production cycle is long, and the cost is high, especially for some quartz materials that require high material performance. For ceramic products, the traditional casting device is far from meeting the requirements, and the casting device currently on the market generally flows the mud into the mold through the action of gravity. The structure will change with the change of temperature, so the hardness of the molded ceramic products is low. Contents of the invention [0003] The present invention provides a casting device for making fused silica ceramics, which can effectively solve the problem of un...
