Description

Technical Field

[0001] The utility model relates to the technical field of ceramic processing taking-out fixtures, in particular to a taking-out fixture for precision ceramic injection blanks. Background Art

[0002] Ceramic injection molding technology is a rapid prototyping technology, which is characterized by being suitable for preparing parts with complex shapes and high dimensional accuracy requirements, and being able to achieve automated continuous production.

[0003] In the production of existing ceramic products, it is often necessary to move ceramic blanks, such as transferring ceramic blanks to a high-temperature furnace, or transferring ceramic blanks out of a high-temperature furnace. This process usually requires the use of a fixture to clamp the ceramic blank.

[0004] The Chinese patent document with application number 201720342896.0 discloses a ceramic blank clamp: the first cylinder and the second cylinder can drive the first clamping member and the second clamping member to approach and separate from each other to clamp and release the ceramic blank; when clamping the ceramic blank, multiple first cylinders apply clamping pressure at different positions of the first elastic steel sheet, and at the same time cause the first elastic steel sheet to undergo elastic deformation to adapt to the curvature of the outer curved surface of the ceramic blank.

[0005] When the shape of the ceramic blank changes, the contact between the first elastic steel sheet and the ceramic blank will be reduced until it becomes a line contact. When the contact area between the arc plate and the ceramic blank is small, if the clamping force is large, the right angle of the first elastic steel sheet will cause the ceramic blank to be clamped. When the clamping force is small, the friction force is too small due to insufficient contact area, which will cause the ceramic blank to rotate or even fall off. Utility Model Content
