Abstract

PURPOSE:To obtain a general-purpose flask which can be easily formed to the desired flask height by constituting of a movable cheek middle flask as ascendable/descendable and a fixed check middle flask. CONSTITUTION:A metallic flask 3 is set on a lower base plate 2 providing a pattern 1. On this metallic flask 3, the cheek middle flask composing of the fixed cheek middle flask 4 and the movable cheek middle flask 5, is laid. Succes sively, the above movable cheek middle flask 5 is ascended/descended through a cylinder, etc., to form the desired flask height. After that, molding sand 7 is charged from upside of the movable check middle flask 5 and after flattening the sand, the molding sand 7 is rammed with an upper base plate 6. After that, by removing the above cheek middle flasks 4, 5, the pattern projected from the upper end surface of the metallic flask 3 is safely and easily molded at good efficiency.

Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は、鋳枠の改良に関するものであり、詳しくは、
継ぎ枠を備えた鋳枠に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvement of a casting flask, and in detail:
This invention relates to a casting flask equipped with a joint frame.

ある。(Prior art and problems to be solved) Conventionally, when the model is large and the flask is small, a flask with the required flask size is formed by adding a joint frame to the flask. Foundry Terminology Dictionary 2nd Edition (April 20, 1980) Nikkan Kogyo Shimbun P158) When using various models during molding, the joint frames had to be replaced each time, resulting in an increase in the number of joint frames owned. This also causes the problem of increased man-hours for frame replacement. The present invention has been made to solve these problems and provides a highly versatile joint frame.

（課題を解決するための手段） 本発明は、昇降自在な可動継ぎ枠と固定継ぎ枠とを備え
た鋳枠である。(Means for Solving the Problems) The present invention is a casting flask that includes a movable joint frame that can be raised and lowered and a fixed joint frame.

造型される。A joint frame consisting of a fixed joint frame 4 and a movable joint frame 5 which is movable up and down is placed on the metal frame 3, and the movable joint frame 5 is formed to be movable up and down by a cylinder (not shown). The present embodiment has the above-mentioned configuration, in which the movable joint frame 5 is raised and lowered to form a desired frame height, and then the casting flask 7 is introduced from above the movable joint frame 5, and after sand cutting, the upper surface plate 6 When the casting sand 7 is tamped and the joint frame 4.5 is removed, a mold is formed in which the casting sand 7 surface protrudes from the upper end surface of the metal frame 3 as shown in FIG.

る。(Effects of the Invention) According to the present invention, since it is provided with a movable joint frame that can be raised and lowered and a fixed joint frame, there is no need to replace the joint frame depending on the size of the casting, and it is not necessary to replace metal frames of the same size in a row. Since the metal frame can be easily transported, safety and productivity are improved. Furthermore, it is possible to deal with variations in the compactability value of green sand, and the sand metal ratio for each mold can be maintained. When this flask is used in the two-stage mold filling method, it greatly contributes to reducing defects.
