（産業上の利用分野）
本考案はガスレンジ、ガステーブル等の厨房用
器具に使用するガスバーナーのキヤツプ、即ち、
バーナー本体上面に開設した開口を覆い、バーナ
ー本体との間に炎口を形成するバーナーキヤツプ
をセラミツク材料によりプレス成形するための成
形金型に関する。[Detailed description of the invention] (Field of industrial application) The present invention is a gas burner cap used in kitchen appliances such as gas ranges and gas tables.
This invention relates to a molding die for press-molding a burner cap, which covers an opening formed on the upper surface of a burner body and forms a flame port between it and the burner body, from a ceramic material.
（従来の技術）
従来、ガスレンジ、ガステーブル等に使用する
ガスバーナーは鋳鉄製又はその他の金属製である
が、金属素材は耐熱性に限界があり、また煮汁等
の付着によつて腐食し易いため耐久性が低いもの
であつた。(Prior art) Conventionally, gas burners used in gas ranges, gas stoves, etc. are made of cast iron or other metals, but metal materials have limited heat resistance and are susceptible to corrosion due to adhesion of boiling liquid, etc. Since it is easy to use, its durability was low.
そこで、ガスバーナーを耐熱性、耐蝕性に優れ
たセラミツク製とすることが考えられる。 Therefore, it is conceivable to make the gas burner made of ceramic, which has excellent heat resistance and corrosion resistance.
この場合には当然バーナーキヤツプもセラミツ
ク製とするのであるが、その成形は、装置の簡便
さ、作業性の良さ等を考慮するとプレス成形が適
している。 In this case, the burner cap is of course made of ceramic, but press molding is suitable for its molding in view of the simplicity of the equipment and good workability.
一方、プレス成形には粉状、粒状、団粒状、練
土状のセラミツク材料を使用することが可能であ
るが、前三者はプレス成形したとき成形素地に均
一な密度が得られず、部分的に粗密が生じ、焼成
した場合の歪みの原因になるので、好ましくな
い。 On the other hand, it is possible to use ceramic materials in the form of powder, granules, aggregates, and kneaded clay for press molding, but the former three do not have uniform density in the molded material when press molded, and some This is not preferable because it causes uneven density and causes distortion when fired.
そこで、練土状のセラミツク材料を用いてプレ
ス成形することになるが、この場合歪みが生じる
のはほとんど離型時に原因がある。 Therefore, press molding is performed using clay-like ceramic material, but in this case most of the distortion occurs during demolding.
即ち練土状のセラミツク材料を用いてプレス成
形した成形素地は柔かく変形し易いばかりでな
く、型に被着し易いので、離型により歪みが生ず
ることが多い。 That is, a molded base formed by press molding using a clay-like ceramic material is not only soft and easily deformed, but also easily adheres to the mold, so that distortion often occurs when the mold is released.
また細かく複雑な形状の部分にあつては離型
時、該部分が欠けたり、ひび割れすることも多
い。 Moreover, when parts have fine and complicated shapes, they often chip or crack when released from the mold.
尚、バーナーキヤツプは歪みが生じると、バー
ナー本体への装着に不都合を来たすばりでなく、
炎口の大きさが不揃になり、均一な炎が得られな
かつたり、バーナー本体との嵌め合わせ部分に隙
間が生じ、そこからガスが漏れて炎口以外の部分
に炎が立つ等、性能上、安全上重大な欠陥となる
恐れがある。 In addition, if the burner cap becomes distorted, it may become inconvenient to attach it to the burner body.
The size of the flame opening may become uneven, making it impossible to obtain a uniform flame, or there may be a gap in the fitting part with the burner body, from which gas may leak, causing flames to appear in areas other than the flame opening, resulting in poor performance. Moreover, there is a risk of serious safety defects.
