Description

The invention relates to foundry, in particular, to chill machines with movable and fixed plates for casting a wide range of parts.

The known chill machine includes a movable chisel plate mounted on the guides, on which an ejector device is placed, having a plate with ejectors, and guiding rods on which two shoulders are pivotally attached, interacting with free ends with ejector return stops mounted on a fixed rack, a conical rod and a podruzh.inenny swivel disk with mirrors for the passage of a tapered rod and guide rods mounted on a fixed rack 1.

However, a known chill machine does not provide for the ejection of a casting in a ram open, which reduces its technological capabilities.

The purpose of the invention is to expand the technological capabilities of the machine.

This goal is achieved by the fact that the proposed machine is equipped with a screw with a tapered shank mounted on a fixed rack that interacts with the holes on the swivel disk, and the ejector return stops are made folding.

FIG. 1 shows the proposed machine, plan view; in fig. 2 is a section along A-A in FIG. 1 in FIG. 3 is a section along BB in FIG. 2; in fig. 4 shows a section along BB in FIG. 2; in fig. 5- adjustment of the machine for ejection of the casting at the end of the chill mold with the return of the pushers at the closing of the chill mold.

The chill machine consists of a fixed stand 1 connected by two round guides 2 to a fixed hog P. CLEAN 3. A moving hinged plate 4 is moved along the round guide 2 by a cylinder 5 rigidly mounted on the stand 1.

On the fixed tuck plate 3 fixed 6 for driving the plate 7,

five

on which the ejector 8 or the metal rod 9 are mounted.

A pivot disk 11 is mounted on a rack 1 in a rigidly fixed hinge 10, which freely rotates along the outer surface of a sleeve 12 mounted on a rack 1

The disk 11 is provided with holes through which the rods 13 pass, connected

with ejector emitters 14 semi-chills 15, a tapered rod 16 mounted on plate 4, and a screw 17c with a tapered shank. On the lid 10, cups 18 with adjustable stops 19 are mounted. In the lid 10 a spring 20 is installed, which presses the disk 11 against the conical surface of the rod 16. On the plate 4, the ejector return levers 21 are mounted. One shoulder of the levers 21 is connected with the rods 13, rollers 22 are mounted at the end of the others. On the stand 1 against the rollers 22 there are folding supports 23 of the ejector return levers.

The chill machine works as follows.

After the casting crystallizes, the chill molds are disassembled, and at the beginning of the movement of the plate 4 with semi-cocoon 15 under the action of the cylinder 5, the rod 13 abuts against the rotary disk 11, keeping the ejectors 14 stationary (on the order of 25-35 mm).

The casting 24 remains on the fixed part of the chill mold. Upon further movement of the plate 4, the conical rod 16 enters the hole in the disk 11, which turns: ivaet- s. When the disk 11 is rotated, the axis of the hole is aligned with the axis of the tapered rod 16 and the axis of the holes of the disk 11 with axes

rods 13. The rods are released and then move together with the slab 4. When the casting 24 is pushed, the ejector return levers 21 rotate and move with the plate 4 in this position. At the end of the stroke, the rollers 22 abut against the folding ejectors 23 of the ejector return levers and return the ejectors 14 to the starting position.

The ejection of the casting from the fixed part of the chill mold is carried out by cylinder 6,

To eject the casting, at the end of the chill mold, it is necessary to tilt the stops 23, align the axes of the rods 13 of the ejectors and the holes in the rotary disk, adjust the stops 19 with the screw 17.

After partial crystallization of the casting 24, the metal rod 9 is removed with the help of the cylinder 6, and then the mold is opened, the plate 4 with the half-heel 15 and the casting 24 moves together with the rods 13. At the end of the stroke the rods 13 abut against the adjustable stops 19 and push the casting 24. Return The ejectors 14 are carried out when the chill mold is closed when the thickened parts of the rods 13 are stopped in the cover 10.

Due to the possibility of extrusion of the casting at the beginning and at the End, the chill machine is more versatile than the known chill machine and can be widely used in foundries for mass production of castings.
