Steel Die Spinning Ceramic Forming Machine

technical field

The utility model relates to a steel mold spinning ceramic forming machine.

Background technique

The traditional daily-use ceramic molding machine adopts rolling forming. During the production process, the clay is put into the plaster mold cavity, and the clay is rolled with a roller to form. This production method has a short service life of the plaster mold (about 300 mold times); The waste gypsum mold is put into the environment, the product density is low, the surface is rough, the amount of spray glaze is large, the forming cycle is long, and the production efficiency is low. To this end, in the Chinese invention patent application with the application publication number CN107225652 A, titled "Steel Die Stamping and Forming Device", a steel die stamping and forming device is disclosed, including a motor, a rolling and stamping head of the upper steel die, and a moving linear slide. , moving slider, lower steel mold, hydraulic column, hydraulic oil supply system, lower steel mold stamping platform, hydraulic cylinder, main part, the top of the main part is provided with a motor, the motor main shaft and the upper steel mold are rolled and stamped.
