Abstract

PURPOSE:To make it possible to easily take out a molded body from a mold without requiring troublesome manual operation and valuable carrying-out device and breaking the molding body by a constitution wherein a bottom force consists of a supporting stand and an outer frame which is seated through a part of a sheet-like matter serving as a carrying means on the top surface of the supporting stand. CONSTITUTION:A supporting stand 12 is vertically movable through the actuation of a hydraulic cylinder and positioned and held at the desired position. In the attached drawing, a pin plate 15 and a top force 14 are at their top dead centers and at the same time an outer frame 13 is at its bottom dead center. In addition, the respective pins 15a of the pin plate 15 break through a sheet 22 in the inner hole of the outer frame 13. Under the above-mentioned state, the predetermined amount of powdered ceramic material is charged from a charger 32 into the outer frame 13 so as to be uniformly and quickly filled on the sheet 22 in the outer frame 13 by vibratory action of a vibrator 17. When a top force 14 is shifted to its bottom dead center under the state just mentioned above, the top force 14 fits in the outer frame 13 by the predetermined amount, resulting in compression-molding the ceramic material by both the top force 14 and an upper plate 12a in the outer frame 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compression molding apparatus for powder and granular materials such as ceramic powder and granules.

[Prior art]

In addition, in order to form the above-mentioned molded body by compression molding,
It is common to use a compression molding apparatus for powder and granular materials, which is equipped with a lower die provided on the machine stand and an upper die provided at the lower end of the ram.

[Problem that the invention seeks to solve]

By the way, in such a molding device, after compression molding is completed, the molded product remains in the lower mold, but the molded product can be taken out by the operator by hand, by sliding it on the machine stand, or by removing the mold from the lower mold. It is moved by a predetermined amount from below the upper mold and taken out by suction by an unloading device having a suction means. These methods tend to damage the molded body unless it is firmly fixed. In addition, the manual movement method requires troublesome removal work, the sliding method has the problem of deformation, and the adsorption method requires expensive unloading equipment and is difficult to remove if the molded product is porous. It is impossible to take out the molded body.

Therefore, an object of the present invention is to enable a compression molding apparatus for powder and granular materials to easily take out the molded product without requiring troublesome manual work or expensive unloading equipment, and without damaging the molded product in any way. It is in.

[Means for solving problems]

The compression molding apparatus for powder and granular materials according to the present invention includes a receiving stand provided on a machine base, and an outer frame mold provided on the upper part of the receiving stand so as to be movable up and down and placed on the receiving stand. and a mold that is movable up and down above the outer frame mold, moves back and forth with respect to the outer frame mold, and compresses and molds the powder and granular material accommodated in the outer frame mold between it and the receiving table. A flat plate-shaped receiving means provided with an upper mold and provided on one side of the receiving base at substantially the same height as the receiving base, and stretched along the upper surfaces of the receiving base and the receiving means. The device is characterized in that it is provided with a sheet-like conveying means that is movable from the receiving stand side to the receiving means side.

[Operations and Effects of the Invention] In the compression molding apparatus having such a configuration, the outer frame mold is placed on the receiving base and its upper surface via a part of the sheet-like material of the conveying means, and both constitute the lower mold. Therefore, the powder and granules are accurately compression-molded by the lower mold and the upper mold. After compression molding, if the upper die and the outer frame die are moved upward, the molded article will be placed on the conveying means of the receiving stand. Therefore, when the conveying means is moved, the molded body is received while being placed on the conveying means and is carried out to a predetermined position.

Therefore, according to such a molding device, the molded product can be easily taken out without any troublesome manual work by the operator, but at this time, the molded product does not come into contact with other members, so there is no risk of damage. There is no need for any expensive unloading equipment.
