〔産業上の利用分野〕
この発明は、鋳物用押湯及び押湯の堰折り方法に関する
。DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) [Industrial Field of Application] The present invention relates to a casting feeder and a method for folding the feeder.
従来、鋳物製品において堰折りを行う場合、ハンマー等
によって押し湯に衝撃を与えたり、又、押し湯と鋳物製
品との間の余裕空間に楔部材を圧入させることにより行
っていた。Conventionally, when weir-folding a cast product, it has been done by applying an impact to the riser with a hammer or the like, or by press-fitting a wedge member into the extra space between the riser and the cast product.
しかしながら、このように堰折りを行うと、鋳物製品に
破断面が侵入する、所謂身喰いが発生する場合があり、
鋳物製品の質の低下を招くおそれが発生した。However, when weir folding is performed in this way, the fractured surface may penetrate into the cast product, which is called "self-cutting".
There was a risk that the quality of the cast products would deteriorate.

収部を破断するものである。Further, the weir folding method according to the second invention is the same as the first invention.
, the housing part is broken by applying force from one wall side of the housing part.
第一の発明において、かかる第二発明の方法により押湯
１５の堰折りを行えば、前記したように鋳物製品１１に
身喰いが発生しない状態で堰折りができる。In the first invention, if the feeder 15 is folded by the method of the second invention, the weir folding can be performed without causing any weir in the cast product 11 as described above.
以下、図面に基づいてこの発明の詳細な説明する。 Hereinafter, the present invention will be described in detail based on the drawings.
第１図は第一実施例を示したものであり、図において、
１１は筒状の鋳物製品であり、外側面に棚状の突出部１

角度へよりも小さいものである。FIG. 1 shows the first embodiment, and in the figure,
Reference numeral 11 indicates a cylindrical casting product, and a shelf-like protrusion 1 is provided on the outer surface.
It has 3. Further, 15 is a feeder, which is provided on the upper surface of the protruding portion 13 via a weir 17. Here, the lower surface of the storage part 17 (corresponding to one wall surface of the present invention) and the cast product 11
The angle θ· between the upper surface of the housing portion 17 (corresponding to the opposite wall surface in the present invention) and the wall surface of the cast product 11 is smaller than the angle between the upper surface of the housing portion 17 (corresponding to the opposite wall surface in the present invention) and the wall surface of the cast product 11.
１９は突起物であり、押湯１５の下面において下方向に
向かった状態で一体成形されている。又、２１は余裕空
間であり、この突起物１９と鋳物製品１１の外側面との
間に形成されている。A projection 19 is integrally formed on the lower surface of the riser 15 so as to face downward. Further, reference numeral 21 denotes an extra space, which is formed between this protrusion 19 and the outer surface of the cast product 11.
このように形成された鋳物用押湯において、押湯１５の
堰折りを行うには、

トン・シリンダ機構を利用すればよい。In the casting riser formed in this way, in order to perform the weir folding of the riser 15, an allowance space 2 between the outer surface of the casting product 11 and the protrusion 19 is created.
1, the wedge member 23 may be inserted upwardly into I. When the wedge member 23 is inserted in this manner, as described above, the riser 15 rotates counterclockwise around the housing part 17, and due to the rotational moment, the weir part 17 moves against the wall surface of the cast product. Since it is bent on the surface or along the broken line 25 shown in FIG. 1, the cast product 11 does not suffer from wear. Note that a piston-cylinder mechanism may be used to move the wedge member 23 back and forth.
次に、第２図は第二実施例を示したものであり、筒状の
