Abstract

The utility model provides a centrifugal pressure slurry filling moulding machine for ceramic. The utility model is comprises a frame, a base, a die holder, a chassis, an adjusting screw mandrel, a slurry inlet, a slurry outlet, a slurry delivering pipeline, an electric motor, a driving device and a slurry chamber. The slurry chamber is arranged under the chassis and is movably connected with the base through a rolling bearing. A throughhole is arranged at the bottom of the slurry chamber and is movably connected with the slurry delivering pipeline. A seal ring and the rolling bearing are arranged at the joint. The driving device is composed of a motor, a belt, a driving wheel and a driveshaft of the chassis. The rolling bearing is arranged at the joint between the adjusting screw mandrel and the upper frame. During the slurry filling process with pressure, the utility model enables the die to move in a circle center. Under the centrifugal force and pressure in the die, the slurry is sufficiently attached to the inner wall of the die. So the utility model causes the semi-finished product to be denser and evener, decreases the deficiency of the semi-finished product due to the stagnation of the slurry, and improves the product quality and the acceptance rate after baking. The advantages are more evident for the semi-finished products with complex structures.

Description

A kind of ceramic centrifugal pressure casting machine

Technical field

The utility model relates to a kind of ceramic grout make-up machine, relates in particular to a kind of ceramic centrifugal pressure casting machine.

Background technology

It mainly is to adopt slip casting and roll forming method that conventional batch is produced blank forming mode daily, art ceramics, and for being shaped as non-circular or difform ceramic body, then mostly adopts the slip casing by pressure method of forming.But this method tends to make inhomogeneous, the leakiness of blank structure after the moulding because of mud remains in a standstill, and particularly for the base substrate of some planform complexity, the easier defective that causes influences product quality and sintering qualified rate.

Summary of the invention

For overcoming inhomogeneous, the leakiness of blank structure the slip casing by pressure method of forming makes moulding because of mud remains in a standstill after, influence the deficiency of product quality and sintering qualified rate, the utility model provide a kind of can make moulding after blank structure more closely knit, more even, avoid causing the casting machine of body defect, satisfy the needs that ceramic industry is produced better because of mud remains in a standstill.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of ceramic centrifugal pressure casting machine, structurally comprise framework, base, die frame, chassis, adjusting screw mandrel, pulp inlet, grout outlet, slurry conveyance conduit, also be provided with motor, transmission device and slurry chamber; The slurry chamber is fixedly installed on below the chassis and by rolling bearing and base and flexibly connects, and the bottom of slurry chamber is provided with a through hole, and through hole and slurry input channel flexibly connect, and are provided with sealing ring and rolling bearing in the junction; Transmission device is made up of motor, belt, drive and chassis power transmission shaft, and the chassis power transmission shaft is fixedlyed connected with the chassis; Be provided with rolling bearing in the junction of regulating screw mandrel and upper frame.Its operation principle is: when motor rotates, driving the chassis power transmission shaft by transmission device rotates, thereby driving the chassis rotates, the mould that is placed on above the chassis also rotates thereupon, slurry flows to mould by grout outlet after entering the slurry chamber by pulp inlet and input channel, because this moment, mould was done center of circle motion with the chassis, the slurry that enters in the mould is adsorbed on the die wall by the effect of centrifugal force and pressure fully, realizes injection forming.

Realize the utility model, change the fixed form of traditional ceramics slip casing by pressure machine mould, when carrying out slip casing by pressure, make mould do center of circle motion, because slurry is subjected to the acting in conjunction of centrifugal force and pressure in mould, be adsorbed on the mould inner wall more fully, make base substrate more closely knit, even, reduced because of mud remains in a standstill and caused the defective of base substrate, improve the quality of products and sintering qualified rate, for the complicated base substrate of structure, effect is more obvious especially.
