一般に、射出成形機は成形材本・１をライナ内に投入し
た後材料を加熱溶融させ、プランジャにて型内に圧入す
ることで所望の形状に成形するものである。(Prior Art) In general, an injection molding machine is used to charge a molding material into a liner, heat and melt the material, and then press fit the material into a mold using a plunger to form a desired shape.
このような射出成形機ｔこてＩＣパッケージを成形する
ときは材料が酸化珪素（Ｓ ｉ Ｏｚ）等を用いる関係
」二、ライナは酎）￥８耗性及び耐食性か請求される。When molding an IC package using such an injection molding machine, silicon oxide (SiOz) or the like is used as the material, and the liner is ¥8 wear and corrosion resistant.
このため、従来よりセラミンクス製内筒を外筒体に対し
焼ばめあるいは圧入させてライナを二Φ；構造とし、耐
摩耗性及び耐食性を向上させたものが知られている。For this reason, it has been known that the inner cylinder made of ceramics is shrink-fitted or press-fitted into the outer cylinder to form a liner with a two-Φ structure, thereby improving wear resistance and corrosion resistance.
（発明が解決しようとする問題点）
ところで、ｉ４述したように成形材料を溶融するためラ
イナを２００〜３００℃に加熱すると、前記セラミック
ス製内筒体はほとんど膨張しないのに対し外筒体は著し
く膨張する結果、内筒体が外筒体より抜は出ることがあ
り、故障の原因となっていた。(Problems to be Solved by the Invention) By the way, as mentioned in i4, when the liner is heated to 200 to 300°C to melt the molding material, the ceramic inner cylinder hardly expands, while the outer cylinder expands. As a result of significant expansion, the inner cylindrical body may be pulled out of the outer cylindrical body, causing failure.
本発明はこのような点に鑑みてなされたもので。The present invention has been made in view of these points.
耐芹耗性及び耐食性に慢れると同時に故障の少ないライ
ナを提供するものである。The objective is to provide a liner that has excellent wear resistance and corrosion resistance, and at the same time has fewer failures.
（問題を解決するための手段）
本発明は、外筒体を低線膨張係数の金属とし、この金属
の内側に高線膨張係数の金属を介在してセラミックス製
内筒体を焼ばめあるいは圧入させた構成を右するもので
ある。(Means for Solving the Problem) The present invention uses a metal with a low coefficient of linear expansion as the outer cylinder, and inserts a metal with a high coefficient of linear expansion inside the metal, and shrink-fits or shrinks the inner cylinder made of ceramics. This is the configuration that was press-fitted.
（作 用）
本発明は、ライナ自身が高温となっても外筒体と内筒体
との膨張差は極めて少なく、かつ中間筒体の膨張により
内筒体は外筒体に強固に保持される。(Function) In the present invention, even if the liner itself becomes high temperature, the difference in expansion between the outer cylinder and the inner cylinder is extremely small, and the inner cylinder is firmly held by the outer cylinder due to the expansion of the intermediate cylinder. Ru.
