ステイション自動造型機が開発され、水平割り砂型の造
型時間の短縮、省力化を企っている。(2) Conventional technology Conventionally, in a horizontally split sand mold making machine, sand plow tanks are installed on the upper part of the machine frame in left and right directions, and the sand plow tanks are placed on a table that forms the gap between the sand plow tanks. Upper and lower sand molds were formed using various operations such as a stripper, and after a core was inserted into the hole of the sand mold, the upper and lower sand molds were pushed out to a pouring table using an extrusion mechanism. However, the molding machine has the disadvantage that the molding cycle is slow because various operations such as sand mold molding, core insertion, and extrusion are performed on the same table. Therefore, in recent years, a vertical rotating base is pivotally supported behind the molding section on the table, and four sets of mold flasks are supported above and below the vertical rotating base. A mold flask swiveling part with a protruding part is installed, and while the mold flask swiveling part is intermittently rotated by 90 degrees, the sand mold is formed at the front position, and supported on the upper and lower arm frames at the side and rear positions. Set the core in the sand mold in the mold flask, then align the mold flasks in the upper and lower arm frames on the right side, push the sand mold downward, and push the matched sand mold onto the pouring table on the side. Rotary 4 made to come out
A station automatic molding machine was developed to shorten the molding time and save labor for horizontally split sand molds.
（３）発明が解決しようとする問題点

。(3) Problems to be Solved by the Invention However, in the four-station automatic molding machine, the sand mold in the lower mold flask supported in the lower arm frame is Since the core has to be inserted manually by the worker, the spacing between the upper and lower arm frames is wide, and safety during work is maintained.
従って、第１ステイションである造型部や、第４ステイ

ある。また、第１ステイションである造型部においてマ
ツチプレートの挿入も前後誘導機構で挿入するため前後

困難性があった。Therefore, the time required to guide the upper and lower mold flasks up and down in the molding section, which is the first station, and the frame alignment and extrusion section, which is the fourth station, becomes long, which tends to increase the molding time. Furthermore, since the match plate is inserted in the first station, which is the molding section, by a front-rear guidance mechanism, it is difficult to guide the match plate back and forth or to replace the match plate.

ことにある。The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a 4-station molding machine with an upper mold at the side and rear portions of the second and third stations of the mold flask rotating section. The frame can be rotated upwards to improve workability and safety when setting the core, thereby shortening the gap between the upper and lower arm frames, increasing the efficiency of molding work and reducing equipment costs. Insert a matuchi plate so that it can be measured,
To provide a 4-station automatic molding machine that facilitates replacement, stops a mold flask rotating part, and improves locking reliability.
