体であり、一方端部にブロープレート取付部２を具備し
ており、この取付部２は例えばネジ部２′によりブロー
プレート１０に嵌合する。In FIGS. 1 and 2, reference numeral 1 denotes a hollow metal nozzle body, which is provided with a blow plate attachment part 2 at one end, and this attachment part 2 is attached to the blow plate 10 by, for example, a threaded part 2'. Fit together.
他方端部にはノズルコム係止部４を介してノズル挿入部
３を具備し、該ノズル挿入部３は型式に応じて所定の長
さの円筒となっている。The other end is provided with a nozzle insertion part 3 via a nozzle comb locking part 4, and the nozzle insertion part 3 is a cylinder with a predetermined length depending on the type.
前記ノズルゴム係止部４にはノズルゴム基部６が嵌合、
係止され、ノズルゴム５はノズル挿入部３上に嵌合、装
着しである。A nozzle rubber base 6 is fitted into the nozzle rubber locking portion 4,
The nozzle rubber 5 is then fitted onto the nozzle insertion portion 3 and installed.

する。As shown in the figure, the nozzle rubber 5 consists of a nozzle comb base 6, a nozzle rubber end γ, and a nozzle rubber conical part 8, and the nozzle rubber end 7 has a plurality of radial cuts 9 as shown in FIG.
The incision 9 is opened and closed in a known manner as compressed air is blown into and exhausted from the sandbox (not shown).
第２図に示す如く本発明のぞきノズルのブロープレート
１０との嵌合部周辺には冷却水通路１１を設は加熱金型
からの伝熱を冷却し得る機構としである。As shown in FIG. 2, a cooling water passage 11 is provided around the fitting part of the peep nozzle of the present invention with the blow plate 10 as a mechanism for cooling the heat transferred from the heating mold.
尚、図において１２は上金型、１３は下金型をそれぞれ
略図的に示しである。In the figure, 12 schematically represents an upper mold, and 13 schematically represents a lower mold.
上記の説明ではノズルゴムの例で示したが、コムに限定
されることなく、可撓性材料であればよく、鋳型造型機
の型式によっては耐熱性の可撓性材料を使用するもので
ある。In the above explanation, the nozzle rubber was used as an example, but the material is not limited to a comb, and any flexible material may be used. Depending on the model of the mold making machine, a heat-resistant flexible material may be used.
本発明のぞきノズルは、従来のものの如くノズルゴム５
の端面を直角とせず、前述の如く截頭円錐形又は半球状
として、このような形状の端面に複数個の放射状の切目
９を設けである。The peep nozzle of the present invention has nozzle rubber 5 like the conventional one.
The end face is not a right angle, but is shaped like a truncated cone or a hemisphere as described above, and a plurality of radial cuts 9 are provided on the end face of such a shape.
従って圧縮空気のサンドボックスへの吹込によって前記
切目９が開放されても切目９の基部の変形の程度が直角

ルゴム５先端部の耐用寿命が犬となる。Therefore, even if the cut 9 is opened by blowing compressed air into the sandbox, the degree of deformation of the base of the cut 9 is small unlike in the case where the cut 9 is at a right angle (as shown in Figure 4), and the open portion tends to become large (D >D'), the molding sand is easily blown in a short period of time and provides restoring force to the cut 9, so that the useful life of the tip of the nozzle rubber 5 is shortened.
更に、金属管状のノズル挿入部３を内装しているのでノ
ズルゴム５の保持が確実でありかつノズルゴム部５の熱

ノズルゴム５の耐用寿命が長くなる効果を有し、砂洩れ
等の恐れもな〈従来品に比べて数倍の耐用寿命を有する
特徴を有する。Furthermore, since the nozzle insertion part 3 in the form of a metal tube is installed inside, the nozzle rubber 5 can be held securely, and the heat in the nozzle rubber part 5 can be cooled by heat transfer to the metal nozzle insertion part 3, so that the useful life of the nozzle rubber 5 can be reduced. It has the effect of increasing the durability and there is no risk of sand leakage, etc. (It has a service life several times longer than conventional products.
