SU1217568A1 - Chill mould machine for making castings of the body of revolution type - Google Patents

Description

one

The invention relates to foundry, in particular, to casting in metal molds and can be used in the formation of castings of the type of rotation bodies.

The purpose of the invention is to increase the level of work.

FIG. 1 depicts a compact machine, a slit; in fig. 2 shows section A-A in FIG. one .

The chill machine contains a base 1, on which racks 2 with guides 3 are fixed. The mold-forming parts 4 of the mold are fixed on the supporting wheel platforms 5, mounted on the guides 3, which can be moved in the radial direction. The hinged mechanism for opening the chill mold includes a pull ring 6 and two link levers 7 connected to the pull ring by means of adjustable rods 8.

The vertical movement of the pull ring 6 is carried out with the help of a pull rod 9. The axes of connection of the levers 7 are spring-loaded with respect to the uprights 2. The springs 10 serve to keep the shape of the formed parts of the mold in the working position, and also play the role of a follow-up mechanism, excluding the play formed due to wear of the hinge joints, on the wc work. The tension of the springs is adjusted by moving the rear axles of the springs in the grooves 11 of the uprights 2. In the uprights 2 there are copier grooves 12 in which the axes 13 of the ball 8 are placed .2

peaceful connections of levers and formative parts 4.

Racks 2 are installed in guide chutes 14 of the base on which

their. can be moved in the radial direction when installing the chill molds with different dimensions.

Chill, stan.ok works as follows.

In the initial position

the ring 6 is in the extreme upper position and, through the levers 7, reliably keeps the supporting wheel platforms 5 with the forming parts 4 of the mold attached to them from being displaced in the radial direction. After the metal is cast and the cast is crystallized, the pull ring is moved downwards with the help of a drive. Simultaneous rotation of the levers 7 and displacement of the forming parts 4 takes place - the chill mold is cleared. Casting under its own weight falls into the receiver, which can be a carousel bunker or production line conveyor. After the preparation of the mold for the next casting and the insertion of the rod, the cycle is repeated.

The use of the proposed chill machine improves the reliability of operation by simplifying the design of the mechanism for opening and moving the mold forming parts of the mold and at the same time ensuring the centering of the shaping parts and adjusting their initial position.
