The invention relates to the foundry industry, in particular, vertical gum 1 ma / shik for centrifugal pouring.

According to the main author. For 1011332, a known vertical centrifugal casting machine, which is a multi-stage installation, in which the orientation of the molds relative to the unloading position is carried out using an orientation mechanism containing an L-shaped plate, installed with its base on the top of the drive pulley of each spindle, between its axis of rotation and the peripheral part, as well as, a fixed frame with two. under spring-loaded rollers, and srshteyna with an additional roller, the spring-loaded rollers are horizontally displaced so that their circumference and axis are perpendicular to the base of the l-shaped plate, and the additional RO.LICK is installed in the plane of motion of the upper part of said plate Til.

The disadvantages of this installation are constructive s.pozhnost and low reliability of the orientation mechanism.

The aim of the invention is to improve the reliability of operation. And simplify the design of the machine "

The goal is achieved by those. that in a vertex machine for centrifugal casting, the shape orientation mechanism of the mold contains orienting disks fixed on the tails of the lamb tails with the legs on the side surfaces; -; x, over the unloading position of the parts ;, a spring-loaded plate is installed the radius of which is equal to the distance from the center of the rotary table, the rfo of the axis of rotation of the spindle, pyr herewith the distance between this plate and the axis of rotation of each spindle lies within the interval between the plane; about the boom and the axis of rotation of the pinpindle.

In addition, the long-wearing ones are tsiskies attached to an individual grinch and supply rollers, located with him. on edge

for its limits, with the axis of the rollers parallel to the axis of rotation of the pin five.

In Fig, 1, a prefix vertical machine for centrifugal casting (top view, half a rotary stand. Conventionally not shown) with an oy mechanism; orientation; lz FIG. 2 is a section A-L in FIG. 1, (; and a cut-out of the vertical orientation mechanism; real plane).

The mechanism of orientite ... our consists of, discs with flips on the side surfaces 1j of eccentrically mounted He. shafts of spindles 2, rotated with: tola 3 and arcuate plate 4, - mounted on, c the position of unloading parts in the plane of the orienting disks 1. Plate 4 is equipped with a spring 5 with a rod b for the jib, enip in r eantally , | -1 plane, with the radius of the plate-f H 4 equal to the distance from the center of the rotary CTOjsa 3 to the axis of rotation of the shaft of spindle 2 (R.,), and the distance between plate 4 to the axis of rotation of spindle 2 .1; the range of the interval between the flat; OST, MON: SKY DISC 1 to the axis of the maturing: spindle 2 CH 2 Crom TOio, attached to one of uiTOKOB 6 and.

The proposed verticals of the length for the centrifugal g-it work as follows

Thus, the position of the form 9, connected through the spindle 2 shaft to the disk, is fixed relative to the ejection ate castings. After passing of the segment plates 4 form much focus 9 with the workpiece 10 is stopped at the unloading position, where the automated produced vybivk.a this part.

The technical and economic advantages of the proposed device are an increase in the reliability of the orientation of the injection molds during operation, i.e., the reduction of noise and the simplicity of the design of the orientation mechanism.

The listed advantages of the proposed machine make it possible to increase the stability and reliability of the machine as a whole.
