(54) DEVICE FOR MOLDING WITH CRYSTALLIZED UNDER PRESSURE

one

The invention relates to foundry, in particular, to devices for casting with crystallization under pressure and may find application in machine-building plants in the production of castings.

A known installation for casting with crystallization under pressure, containing a hydraulic press and mechanisms for locking the mold and removing the castings 1.

However, such an installation is complicated and inconvenient in operation, since the mold is manually filled. The use of automatic dispensers in this installation requires an increase in production space.

A device for casting with crystallization under pressure is also known, comprising a matrix, a pressing punch and a dosing chamber, one of the walls of which is rigidly connected with a reciprocating drive 2.

The disadvantage of this device is limited technological capabilities.

The purpose of the invention is the expansion of technological capabilities.

The goal is achieved by the fact that in a device comprising a die, a pressing punch and a dosing chamber.

one of the walls of which is rigidly connected with the drive of the reciprocating movement, the dosing chamber is open and provided with a height-adjustable insert with a cut in the head part.

The drawing shows a device for casting with crystallization under pressure, a general view.

The device contains a pressing punch 1, a matrix 2, a dosing chamber 3, in the wall of which a height-adjustable insert 4 is fixed with a cut in the upper

10 parts of plum izlischkov metal. The part of the wall 5 of the matrix 2 moving in the cavity of the dosing chamber is detachable and rigidly connected to the actuator 6.

The device works as follows.

Before pouring the metal, the punch 1 is in the up position. After pouring the metal into the chamber 3, metering is on. The actuator 6 and the movable part of the wall 5 of the matrix 2 melt is pressed into the mold. The metal leaks merge through the insert 4. After the movable part

20 of the wall 5 of the matrix 2 reaches its leftmost position, the punch 1 is turned on. The metal crystallizes under

pressure. Then the punch 1 lift and remove the casting from the mold. The actuator 6 moves the movable part of the form 5 to the extreme right position. The metal is cast and the cycle repeats.

The proposed device improves the accuracy of melt dosing.

The invention can be used by machine-building plants.
