Description

The invention relates to foundry.

The purpose of the invention is to increase productivity and reduce the complexity of the manufacture of casting molds.

Nz FIG. 1 to 3 depict the steps for producing molds in a three-position casting line unit.

The design of a three-position casting line unit contains a gas-explosive device 1, a two-position trolley 2, a gland table 3, a filling frame 4, a hopper 5, a stretcher 6, a roller table 7, a block 8. a model plate with models 9, hydraulic cylinders 10, the upper yoke 11, lower yoke 12, pressing table 13. filling frame 14. metering hopper 15, extension device 16, roll tables 17, flask 18, model plate 19. hydraulic cylinders 20.

Three-position block casting line works as follows.

In the roller table 7 (Fig. 1), the empty flask 8 is installed above the model plate, the pressure table 3 rises, the box is fixed on the model plate, then pressed against the filling frame 4 and to the metering hopper 5 with the molding mixture.

The flask and filling frame are filled with molding sand. The gland table with the model-anchor equipment is lowered. Then the carriage 2 transports the pressure table 3 with the model-mold tooling, filled with molding sand, to the molding position (Fig. 2). At the same time, the pressure table 13 with the model plate 19 and the filling frame 14 are moved to the dosage position of the moldable mixture. During molding with the help of a gas-explosive device (Fig. 2), on the roller 17, the empty flask 18 is installed under the model plate 19, then pressed against the filling frame 14 and to the metering hopper 15.

a mixture. The gland table with the model-auxiliary equipment is lowered. At the compaction position, the tool is pressed with the molding sand to the combustion chamber and a pulse compaction of the mold.

Claims (2)

Then the carriage 2 moves to the extreme left position. The pressing table 13 with the model-mold tooling, filled with molding sand, is placed at the sealing position (Fig. 3), and on the table 3 the model is pulled, i.e. the cylinders 10 move upwards, the flask rests on the roller conveyor 7, the filling frame is separated from the flask, the finished mold is removed from the molding block. Claim 1. Three-position molding unit casting line containing the top and the lower traverse with the hoppers and molding head mounted on the upper traverse, a two-stage transport device with two model kits and flasks moved on it, characterized in that, in order to increase productivity and reduce the labor intensity of the manufacture of casting molds, the vehicle is made in the form of a trolley, on which movable tables and vertically located hydraulic cylinders with filling frames rigidly fixed on their rods and installation roll tables are placed Opok. 2. The unit according to claim 1, characterized in that the molding head is made in the form of a gas explosive device. 1 // FIG. 2
