Description
【0001】[0001]
本考案は、砂型を模型から離型するための押上げ治具に関する。 The present invention relates to a lifting jig for releasing a sand mold from a model.
【0002】[0002]
従来から深い溝やシマを有する鋳造品の成形に際しては、模型に対して砂型の 離型が困難であった。これは砂型がもろく深い溝やシマの場合に砂型の引出しや 押出しに際して模型との間に引張り力が作用するため砂型が崩れるおそれがあっ た。 In the past, it was difficult to release the sand mold from the model when molding a cast product with deep grooves and stripes. When the sand mold is fragile and has deep grooves or stripes, a tensile force acts between the sand mold and the model when the sand mold is pulled out or extruded, which may cause the sand mold to collapse.
【0003】[0003]
このため模型に僅かな抜き勾配を設けて抵抗を少なくして離型することが行わ れている。したがって深い溝やシマを形成するには成形品に対して研磨や研削に よる手段が必要とされている。 For this reason, a slight draft is applied to the model to reduce the resistance and the mold is released. Therefore, in order to form deep grooves and stripes, it is necessary to have means for polishing or grinding the molded product.
【0004】[0004]
本考案は、砂型の深い溝やシマの模型に接している下面部分全面に模型よりや や小さい(0.2〜0.5mm)模型と同一形状の砂型押上げ治具を用いて砂型 を押上げて離型するもので、この治具は模型取付台を貫通した下側にある押出し 板に固定されている構成となっている。 The present invention uses a sand mold lifting jig of the same shape as the model, which is slightly smaller (0.2 to 0.5 mm) than the model, to push the sand mold over the entire bottom surface in contact with the deep groove of the sand mold or the model of the stripe. It is lifted and released from the mold, and this jig is configured to be fixed to the lower extrusion plate that penetrates the model mount.
【0005】[0005]
したがって本考案によるときは、砂型と模型の間隙が極めて小さく形成するこ とにより砂型と模型の離型の際、離型抵抗より砂型の圧縮強度が大きいので型抜 き勾配は必要なく型抜きが可能となる。これは従来は砂型の深い溝やシマの一部 あるいは全部が引張り荷重を受けるのに対して本考案の治具によるときは、深い 溝やシマの部分全面が圧縮荷重を受けるためで砂型の引張り荷重測定は殆どでき ない値に対して、砂型の圧縮強度は極めて大きく、生砂型法では1.3〜5kg /cm2熱硬化法およびガス硬化法では20〜40kg/cm2の圧縮強度にな るため本考案による押上げ治具を使用するときは全く問題のない砂型の成形が可 能となるものである。Therefore, according to the present invention, when the sand mold and the model are separated from each other by forming the gap between the sand mold and the model to be extremely small, the compression strength of the sand mold is larger than the mold release resistance. It will be possible. In the conventional jig, the whole or part of the deep groove or stripe receives a compressive load. against a load measurement can hardly value, the compressive strength of the sand mold is extremely large in the green sand molding method I compressive strength of 20~40kg / cm 2 in 1.3~5kg / cm 2 heat-curing method and a gas curing technique Therefore, when using the push-up jig according to the present invention, the sand mold can be molded without any problem.

添付図面により本考案の砂型押上げ治具を説明する。本考案は例として図に示 すような深い溝やシマ(2)のある円筒形の砂型(1)について説明する。図1 は本考案の砂型(1)を押上げ離型する治具(7)の実施例図であって、図にお いて(1)は砂型であり、(2)は砂型(1)に形成されている深い溝やシマを 示している。したがって砂型(1)を成形する模型(3)にはこれと対象的に溝 やシマを形成するための突部(4)が形成されている。(5)は模型取付台を示 していて模型(3)は取付台(5)上に装置されている。(7)は砂型押上げ治 具であって取付台(5)を貫通して上下に移動するように構成されている。 The sand mold lifting jig of the present invention will be described with reference to the accompanying drawings. As an example, the present invention describes a cylindrical sand mold (1) having deep grooves and stripes (2) as shown in the figure. FIG. 1 is an embodiment diagram of a jig (7) for pushing up and releasing the sand mold (1) of the present invention, in which (1) is a sand mold and (2) is a sand mold (1). It shows the deep grooves and stripes that have been formed. Therefore, the model (3) for molding the sand mold (1) is provided with the projections (4) for forming grooves and stripes in contrast to this. (5) shows a model mount, and the model (3) is mounted on the mount (5). (7) is a sand-type lifting tool, which is configured to penetrate the mount (5) and move up and down.
【0007】 図2を参照して、治具(7)の平面形状は砂型(1)の底面部全面に模型(3 )よりやや小さい同形に形成されている。したがって図1の実施例図にても理解 できるように模型(3)と砂型(1)の間には極く僅かな間隙(9)が形成され 、これによって離型に対して生じる引張り抵抗を吸収するものである。With reference to FIG. 2, the jig (7) is formed in the same shape as the model (3) on the entire bottom surface of the sand mold (1). Therefore, as can be understood from the embodiment diagram of FIG. 1, a very small gap (9) is formed between the model (3) and the sand mold (1), which causes the tensile resistance against the mold release. It absorbs.
【0008】 図3は砂型(1)と模型(3)の配置関係を示す断面図であって、この本考案 の押上げ治具(7)が模型取付台(5)を貫通して砂型(1)を上方に押上げ離 型するもので、治具(7)が砂型(1)の底面の全面に当接しながら離型を行う 。FIG. 3 is a cross-sectional view showing the positional relationship between the sand mold (1) and the model (3). The push-up jig (7) of the present invention penetrates the model mount (5) and the sand mold ( 1) is pushed up and released from the mold, and the jig (7) releases the mold while contacting the entire bottom surface of the sand mold (1).

このように本考案の治具によるときは砂型と模型の離型の際に砂型と模型との 間に極めて小さな間隙があり、離型抵抗よりも砂型の圧縮強度が大きくなって型 抜き勾配を付す必要がなく、したがって精密な砂型を成形することができるとい う従来の砂型の離型手段にはみられない卓越した効果を奏する。 As described above, when the jig of the present invention is used, there is an extremely small gap between the sand mold and the model when the mold is released from the sand mold. Since it does not need to be attached, it is possible to form a precise sand mold, and it has an outstanding effect not found in the conventional mold releasing means for sand molds.
