本考案は、ラバ−プレス成形法に使用する成形型に関するものである。 The present invention relates to a mold used in a rubber press molding method.
【０００２】0002
従来、粉体材料の成形に利用される方法にラバ−プレスと呼ばれる方法がある 。このラバ−プレス成形法は、粉体をゴム型に充填して密閉し、このゴム型をプ レスの圧力容器内に入れ、静水圧により四方から均等に加圧して粉体の成形を行 なう方法である。 以下、セラミックス製エンジン用バルブのラバ−プレス成形型について説明す る。図３Ａはゴム型を治具に取付けた正面図、図３Ｂは図３ＡのＸ−Ｘ線の断面 図、図４は一部の拡大図である。両端が開口したほぼ円筒形のゴム型15にセラミ ックスの粉体成形材料16を充填し、ゴム型15の両端開口部をそれぞれ金型11，12 で密閉し、この成形型を治具に取付けてプレスの圧力容器に入れ、周りから静水 圧を加えて成形している。治具は、上下の金属製プレ−ト10，10間に３本の支柱 13を配置し、上方の金属プレ−ト10には、把手14を設けてある。 金型11とゴム型15との接合部は、図４に示すように、粘着テ−プ17で密封固定 する。上部の金型12についても同様である。 特開昭６２−２２４４９８号公報には、成形品の主要表面に対応する表面を非 弾性体とし、補助表面に対応する表面を弾性体で構成したラバ−プレス用成形型 が提案されている。 Conventionally, there is a method called rubber press used for molding powder materials. . This rubber press molding method involves filling a rubber mold with powder and sealing it. The powder is then placed in a pressure vessel with hydrostatic pressure applied evenly from all sides to form the powder. This is the way to do it. The rubber press mold for ceramic engine valves is explained below. Ru. Figure 3A is a front view of the rubber mold attached to the jig, and Figure 3B is a cross section taken along line X-X in Figure 3A. Figures 4 and 4 are partially enlarged views. Ceramic is placed in a nearly cylindrical rubber mold 15 with open ends. Fill the powder molding material 16 of the rubber mold 15 with molds 11 and 12, respectively. This mold is then attached to a jig and placed in the pressure vessel of the press. It is molded by applying pressure. The jig has three supports between the upper and lower metal plates 10 and 10. 13, and a handle 14 is provided on the upper metal plate 10. The joint between the mold 11 and the rubber mold 15 is sealed and fixed with adhesive tape 17, as shown in Figure 4. do. The same applies to the upper mold 12. JP-A No. 62-224498 discloses that the surface corresponding to the main surface of the molded product is Rubber press mold with an elastic body and a surface corresponding to the auxiliary surface made of an elastic body is proposed.

上記従来のラバ−プレス用成形型は、これを取付ける治具が大型で金属製であ るので重くなり、運搬用に把手14を設けている。このため、益々大型になり、プ レスの圧力容器に少ししか入らず、大量生産に不向きとなる。 また、金型11とゴム型15とを粘着テ−プ17で密封固定するのに熟練を要し、金 型をセットしたゴム型を治具に取付けるのにも時間がかかる The conventional rubber press mold mentioned above requires a large and metal jig to mount it. Since it is heavy, a handle 14 is provided for transportation. For this reason, the size of the printer is increasing. Only a small amount can fit into a low pressure vessel, making it unsuitable for mass production. In addition, it requires skill to seal and fix the mold 11 and the rubber mold 15 with the adhesive tape 17. It takes time to attach the rubber mold with the mold set to the jig.
【０００４】 本考案は、上記の課題を解決し、成形型を小型軽量とし、セット作業を容易と して生産性の向上を図ることを目的とするものである。0004 This invention solves the above problems, makes the mold smaller and lighter, and makes setting work easier. The purpose of this is to improve productivity.

ゴム型の外側に治具を嵌合し、ゴム型の内部に粉末材料を充填し、Ｏリングを 取付けた分割型をゴム型の開口端に嵌合して分割型を締付けると、Ｏリングが張 出してゴム型の内面に押付けられて固定される。 この成形型をプレスの圧力容器に入れて静水圧を加えると、圧力媒体が治具の 孔を通ってゴム型の周面にも加わり、ゴム型に充填した粉体材料が成形される。 Fit the jig to the outside of the rubber mold, fill the inside of the rubber mold with powder material, and insert the O-ring. When the attached split mold is fitted into the open end of the rubber mold and the split mold is tightened, the O-ring will be stretched. It is taken out and pressed against the inner surface of the rubber mold and fixed. When this mold is placed in the pressure vessel of the press and hydrostatic pressure is applied, the pressure medium is released into the jig. The powder material passes through the holes and is applied to the circumferential surface of the rubber mold, and the powder material filled in the rubber mold is molded.

【０００８】 次ぎに、本考案の成形型の使用法を説明する。 ゴム型５の外側に治具７を嵌合し、ゴム型５の内部にセラミックスの粉末材料 ６を充填する。ボルト４を弛めた状態でＯリング３を取付けた型１，２をゴム型 ５の開口端に嵌合し、ボルト４を締めると、Ｏリング３が型２の傾斜面２ａで外 側に張出してゴム型５の内面に押付けられ、ゴム型５の外側に治具７が嵌合され ているので、分割型１，２はゴム型５に固定される。 この成形型をプレスの圧力容器に入れ、静水圧を加えると、圧力媒体が治具７ の孔８を通ってゴム型５の周面にも加わり、ゴム型５に充填した粉体材料６が成 形される。[0008] Next, how to use the mold of the present invention will be explained. A jig 7 is fitted on the outside of the rubber mold 5, and a ceramic powder material is placed inside the rubber mold 5. Fill 6. With bolt 4 loosened, molds 1 and 2 with O-ring 3 attached are rubber molds. When the O-ring 3 is fitted into the open end of the mold 2 and the bolt 4 is tightened, the O-ring 3 is released on the inclined surface 2a of the mold 2. It is pushed out to the side and pressed against the inner surface of the rubber mold 5, and the jig 7 is fitted on the outside of the rubber mold 5. Therefore, the split molds 1 and 2 are fixed to the rubber mold 5. When this mold is placed in the pressure vessel of the press and hydrostatic pressure is applied, the pressure medium is released into the jig 7. The powder material 6 that has been filled in the rubber mold 5 is also added to the peripheral surface of the rubber mold 5 through the hole 8 of the mold. Shaped.
