Abstract

PURPOSE:To contrive to prevent bulge and burr on a product from occurring and to enhance the dimensional accuracy by a structure wherein pressing blades, the tilt angle of the inner surface side incline of each of which is made to be at nearly 90 degrees to a pressing face and at the same time the tilt angle of the outer surface side incline of each of which is made to be inclined to the vertical axis at a predetermined angle, are provided and the outer peripheral flange faces of the pressing blades are made to be lower than the pressing face. CONSTITUTION:Pressing blades 3 are implanted along the outer shape of a product. A pressing face 2 is a portion, which is surrounded by the pressing blades 3 and onto which projecting and recessed pattern is formed. As for the shape of the pressing blade 3, the tilt angle of the inner surface side incline 4 of the pressing blade is made to be at nearly 90 degrees to the pressing face 2 and the title angle of the outer surface side incline 5 is made to be inclined outwards by 22-45 degrees to the vertical axis. The outer peripheral flange faces 6 of the pressing blades 3 are made to be lower than the pressing face 2. When a green sheet is pressed with the above-mentioned pressing tool A, projecting and recessed pattern 7 is produced by the pressing face 2 and at the same time cut-off parts 8 are produced with the pressing blades 3 and cut off. When a product 10 is pressingly cut off with said pressing blades 3, bulge, burr and the like are difficult to develop on the product.

。In the structure of a press die that presses a green cement sheet (green sheet) to form a pattern on its surface, the present invention has a press blade installed on the right side of the press surface of the die in a shape that follows the outer shape of the product. A press blade is provided in which the angle of the inner inclined surface of the blade is formed at a substantially right angle to the press surface, and the angle of the outer inclined surface of the press blade is inclined from 22 degrees to 45 degrees with respect to the vertical axis. This relates to the structure of a press mold in which the outer peripheral flange of the press mold is lower than the press surface.

〔実施例〕〔Example〕

第１図及び第２図において、Ａはプレス金型、１は基台
、２はプレス面、３はプレス刃である。In FIGS. 1 and 2, A is a press die, 1 is a base, 2 is a press surface, and 3 is a press blade.

。The pressing surface 2 presses the green sheet to give it a surface pattern and increase its density. The press blade 3 is implanted in a shape that follows the outer shape of the product, and the press surface 2 is attached to the press blade 3.
This is the area surrounded by , and an uneven pattern is formed. The shape of the press blade 3 is such that the angle of the inner inclined surface 4 is approximately perpendicular to the press surface 2, and the angle of the outer inclined surface 5 is inclined outward by 22 degrees to 45 degrees with respect to the vertical axis. There is.

このプレス刃３の外面側傾斜面５の角度として特定の角
度を選択しているのは実験の結果による。The reason why a specific angle is selected as the angle of the outer inclined surface 5 of the press blade 3 is based on the results of experiments.

プレス刃３の外周鍔部６はプレス面２より低（形成され

側にフクレ、パリ等が発生しないものである。耳部９の
上面１２は製品１０の上面より高い位置になっている。The outer periphery flange 6 of the press blade 3 is formed lower than the press surface 2. When a green sheet is pressed with this press die A, an uneven pattern 7 is formed by the press surface 2 as shown in FIG. A cutting part 8 is formed and cut by the press blade 3. Reference numeral 9 is an ear part.When the green sheet is pressed and cut by the press blade 3 and the product 10 is cut out, the product 10 has blisters, cracks, etc. In other words, because the press blade 3 has a specific shape, the material escapes to the ear part 9 and becomes the escape part 11.
No blisters, flakes, etc. will occur on the sides. The upper surface 12 of the ear part 9 is located at a higher position than the upper surface of the product 10.

理由はプレス刃３の外周鍔部６がプレス面２より低く形
成されているために製品１０の部分には大きな圧力がか
がり耳部９には小さな圧力がかかる為、材料が耳部９に
逃げることができ製品１０を精度良く切断でき、切断後
の寸法変化も小さいものである。The reason is that because the outer periphery flange 6 of the press blade 3 is formed lower than the press surface 2, a large pressure is applied to the product 10 part and a small pressure is applied to the ear part 9, so that the material escapes to the ear part 9. Therefore, the product 10 can be cut with high precision, and dimensional changes after cutting are small.

精度も良いものであるThe structure of the press mold of the present invention is that in the structure of a press mold that presses a green cement sheet (green sheet) to form a pattern on the surface, the press blade is placed on the press surface of the mold in a shape that follows the outer shape of the product. A press in which the angle of the inner inclined surface of the press blade is approximately perpendicular to the press surface, and the angle of the outer inclined surface of the press blade is inclined from 22 degrees to 45 degrees with respect to the vertical axis. Since the press blade is equipped with a blade and the outer flange of the press blade is lower than the press surface, the press blade can form an uneven pattern on the green sheet and cut the product at the same time, allowing blisters, cracks, etc. to escape to the edges. Blisters, flakes, etc. do not easily occur on the product side, and the dimensional accuracy of the product is also good.
