Die mechanism of vibration molder with slide block on middle part and operation method thereof

Abstract

The invention belongs to the technical field of refractory material formation and provides a die mechanism of a vibration molder with a slide block on the middle part and an operation method thereof. The die mechanism comprises a die body (1), an upper template (3), a lower template (5), a molding frame (4), a pre-pressing slide block (2) and a driving body, wherein the pre-pressing slide block (2) and the driving body are arranged up and down; the pre-pressing slide block (2) is connected with the driving body, when pre-pressing is performed under the action of the driving body, the pre-pressing slide block (2) extends downwards to press materials in the molding frame (4), and after pre-stressing is finished, the pre-pressing slide block (2) retracts upwards, so that the lower end surface of the pre-pressing slide block (2) is aligned with the lower end surface of the upper template (3). The amount of the air pressed into a molded blank body is effectively reduced, and the occurrence that the finally molded blank body has a laminated defect is avoided. The die mechanism has the advantages of reliable molding and high molding efficiency.

Description

technical field [0001] The invention belongs to the technical field of refractory molding, and mainly relates to a die head mechanism of a vibration molding machine with a slider in the middle and an operation method thereof. [0002] Background technique [0003] The semi-dry vibration molding of shaped refractory products is essentially a process in which the particles or fine powder in the mud gather under the action of external pressure and form a dense green body with the discharge of air. Whether there are lamellar cracks in the brick forming process is closely related to the amount of air that is pressed into the forming mud. The literature "Research on the air permeability of brick bricks formed by semi-dry method" (Foreign Refractory Materials, 1997 (9): 49-52) mentioned In the compacting process of adobe compaction, in order to discharge air from the formed adobe, it is necessary to increase the air permeability of the adobe, but the air permeability of the adobe f...

AI Technical Summary

Problems solved by technology

[0009]Through the above different technical methods, the quality and yield of bricks have been greatly improved, but there are more or less problems, such as: setting on the mold Vent hole, after a period of molding, the powder often blocks the air hole, and it is troublesome to clean up; the frequency conversion and amplitude modulation scheme needs to greatly prolong the molding time, which reduces the molding efficiency; vacuuming requires additional vacuum equipment and lower operability
