本発明は主としてホットプレス後のスリーブと炭化珪素
焼結晶との離型を良くするものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention is primarily concerned with improving the release of a sleeve and sintered silicon carbide crystal after hot pressing.
従来、ホットプレス用のスリーブと炭化珪素焼結晶の離
型を良くするものは用いられておらず、ホットプレス後
、スリーブと炭化珪素焼結晶とが固着するため焼結晶を
取出すにはスリーブを割らなければならなかった。この
ためスリーブの使用が１回限りで、その都度新品のスリ
ーブを使用しなければならない欠点があった。Conventionally, a sleeve for hot pressing and a material that improves the release of silicon carbide sintered crystals have not been used, and since the sleeve and silicon carbide sintered crystals stick together after hot pressing, it is necessary to break the sleeve to remove the sintered crystals. I had to. Therefore, the sleeve can only be used once, and a new sleeve must be used each time.
本発明の目的はホットプレス後のスリーブと炭化珪素焼

できる。The purpose of the present invention is to improve the mold release between the sleeve and silicon carbide fired crystal after hot pressing, by applying or applying a sheet or paste containing carbon as a main component to the inside of the sleeve. It is possible to prevent the sintered crystal from sticking to the sleeve and take out the sintered crystal without breaking the sleeve.
従来法だとスリーブが焼結晶と固着して１回限りでダメ

ペーストを当て或いは塗布しスリーブと焼結晶の離型を
良くしたものである。このため焼結晶及びスリーブ自身
も破壊せず、スリーブの寿命が大巾に延びる。With the conventional method, the sleeve would stick to the sintered crystal and fail after just one use, so this method is based on applying a mold release agent to the mold, which is used when manufacturing castings. From this, a sheet or paste containing carbon as a main component is applied or applied to the inside of the sleeve to improve mold release between the sleeve and the fired crystal. Therefore, neither the fired crystal nor the sleeve itself is destroyed, and the life of the sleeve is greatly extended.
本発明の実施例を第１図および第２図によシ説明する。 An embodiment of the present invention will be explained with reference to FIGS. 1 and 2.
第１図は従来法、第２図は本発明による方法。FIG. 1 shows the conventional method, and FIG. 2 shows the method according to the present invention.
従来は炭素を主成分とするダイ１の内側に炭素を主成分
とするスリーブ２を焼結晶５と接し、上下方向は炭素を
主成分とするスペーサー４を介して炭素を主成分とする
パンチ３にて加圧するものである。Conventionally, a sleeve 2 mainly composed of carbon is placed inside a die 1 mainly composed of carbon, and a sleeve 2 mainly composed of carbon is in contact with a sintered crystal 5, and a punch 3 mainly composed of carbon is inserted through a spacer 4 mainly composed of carbon in the vertical direction. Pressure is applied at
本発明によるものは第２図のスリーブ２の内側に炭素を
主成分とするシートまたはペースト６を当て或いは塗布
しホットプレスするもので、加圧方法は従来法と同じで
ある。In the method according to the present invention, a sheet or paste 6 mainly composed of carbon is applied or applied to the inside of the sleeve 2 shown in FIG. 2 and hot pressed, and the pressing method is the same as the conventional method.
従来法と本発明による方法とを比較すると、従来法では

ーブの使用回数が１回限シであった。本発明による方法
では、スリーブと焼結晶との固着がなく、スリープの使
用回数が大巾に増加する。Comparing the conventional method and the method according to the present invention, in the conventional method, the sleeve had to be broken in order to take out the fired crystal because the sleeve and the fired crystal were stuck together. For this reason, the sleeve could only be used once. In the method according to the present invention, there is no adhesion between the sleeve and the fired crystal, and the number of times the sleeve can be used is greatly increased.
また、従来法のスリーブと本発明のシートまたはペース
トは共に炭素を主成分とするものであり、焼結晶に対す
る影響は無かった。Furthermore, both the sleeve of the conventional method and the sheet or paste of the present invention have carbon as a main component, and had no effect on the sintered crystals.

結晶およびスリーブ自身も破壊しない。このためスリー
ブの寿命が大巾に延びる効果がある。According to the present invention, the sleeve and the sheet or paste do not stick together after hot pressing, and neither the fired crystal nor the sleeve itself is destroyed when the fired crystal is removed from the sleeve. This has the effect of greatly extending the life of the sleeve.
