Description

one

The invention relates to foundry, in particular, to machines for making molds.

A known molding machine comprising a working table with piston drives, at the ends of which T-shaped heads are fixed for fixing a model plate having through-through. Shaped grooves 1}.

The disadvantage of this machine is the difficulty arising from the replacement of model plates.

The purpose of the invention is to provide a quick change of the model plate.

This goal is achieved by the fact that the machine is equipped with a roller table mounted on T-shaped heads and guides made in the slots of the model plate.

.In FIG. 1 shows the molding machine: 11, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2

The molding machine contains model plates 1 and 2 with models 3 and 4, work table 5, with pistons attached to it by drives 6, with rods 7 with C-shaped heads 8. Model plates 1 and 2 are equipped with nPR1EVLYU1ZMI 9, which are housed in

through T-slots 10. On the T-shaped heads 8 of the rods 7, a roller table 11 with rollers 12 is installed. RoAgangi 13 and 14 are installed along the movement of the model plates 1 and 2. The pusher 15 serves to move the model plates.

The molding machine works as follows.

ten

In the initial position, the model plate 1 with model 3 is pressed with T-shaped heads 8 rods 7 piston actuators 6 to the work table 5. To change the model plate 1 with model 3

15 include piston actuators 6 and rods 7 with T-heads B move upward, freeing model plate 1. Roller conveyor 11 with i2 rollers fixed on T-shaped

20 heads 8, also moves upwards. The rollers 12 come into contact with the guides 9. With further upward movement of the rods 7 of the piston actuators 6, the model plate 1 is brought to

25, the transport level of the roller tables 13 and 14 and is removed from the fixing pins of the desktop. The pusher 15 operates, pushing along the roller table 13 a new model plate 2 with the model

30 4 on the rollers 12, which are mounted on the work table 5, simultaneously pushing out the spent model plate 1 with the model 3 on the live rolls 14. After the model plate is installed above the work table 5, the piston actuators 6 are turned on, the rods 7 are lowered down and T-shaped heads 8 are pressed: model plate 2 with model 4 to work table 5 and the machine is ready for operation. Invention Form A molding machine comprising a working table with piston drives at the ends of the rods of which T-shaped heads are fixed for fixing a model plate having through T-shaped grooves, which, in order to ensure a quick change of the model plate, is equipped with a roller table, mounted on T-shaped heads and guides made in the slots of the model plate.
