この発明は中子ケレンの固定法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing a core.

に示すように各ボア入子5,6,7,8間に1個
所だけケレン19を使用していたが中子1の形状
によつては1個所だけのケレンでは中子1の変
形、折損の防止が不十分なためケレンを2個所以

方法ではケレンの取付位置のばらつき、中子砂の
ケレンへの巻きつき不良、ケレンの埋め込み時間
の増加等の問題があつた。 Conventionally, when casting a water jacket for a cylinder block of an engine, for example, the water jacket core may be deformed or broken. In order to prevent the water jacket core from being deformed or broken, a burr 19 is generally used at only one location between each bore insert 5, 6, 7, and 8, as shown in Figures 5 to 7. However, depending on the shape of the core 1, kerating in only one place may not be sufficient to prevent deformation or breakage of the core 1, so two or more burrs may be required. The keren from the second place was embedded. This method had problems such as variations in the mounting position of the keratin, poor winding of the core sand around the kern, and an increase in the time required to embed the dente.
この発明は中子造型時に複数のケレンを容易に
所定位置に設置固定できる方法の提供を目的とす
る。 The object of the present invention is to provide a method by which a plurality of kerens can be easily installed and fixed in a predetermined position during core molding.
上記目的を達成するためこの発明は複数のケレ
ンを一対のピースにより保持し、一対のピースを
中子造型時の中子組み付け部材により保持するこ
とを特徴としている。 In order to achieve the above object, the present invention is characterized in that a plurality of cores are held by a pair of pieces, and the pair of pieces is held by a core assembly member during core molding.
以下実施例を示す図面によりこの発明を説明す
る。第1図乃至第3図において、2,16,1
7,18はケレンであり、これらは矩形状の対向

形成される8個のケレン保持孔20内に保持され
ている。11〜15は中子外壁部型である。 The present invention will be explained below with reference to drawings showing embodiments. In Figures 1 to 3, 2, 16, 1
7 and 18 are kerens, which are formed between the opposing surfaces of a pair of pieces 3 and 4 having rectangular opposing surfaces and between the pieces 3 and 4 and the bore inserts 5, 6, 9, and 10. It is held in eight keren holding holes 20. 11 to 15 are core outer wall types.
中子1が硬化すると第3図に示すようにボア入

第4図はピース3を示し、イは平面図、ロは正面
図、ハは側面図を示す。 When the core 1 is hardened, the bore inserts 5, 6, 9, 10 and pieces 3, 4 are removed from the mold as shown in FIG. As a result, the core 1 has 8 pieces 2, 16,
17 and 18 to prevent deformation and breakage of the core 1 during water jacket casting. In addition,
FIG. 4 shows piece 3, in which A shows a plan view, B shows a front view, and C shows a side view.
この発明は上述のように所望の鋳造品用の中子

に際し中子の変形、折損がなくなり均等な品質の
鋳造品が得られる。 As described above, this invention is such that a plurality of kerens are held by a pair of pieces during the molding of a core for a desired casting product, and the pair of pieces is held by a core assembly member for molding the core. because there is,
The workability and accuracy of attaching the keren are improved, and the ability of sand to wrap around the keren is also improved. As a result, there is no deformation or breakage of the core during casting, and a cast product of uniform quality can be obtained.
