Description

The invention relates to foundry, namely, to the design of chill machines, mainly for, and for hollow castings.

Closest to the invention is a chill machine containing. a bed mounted on the upper and lower subcutaneous plates of the semi-heel and an intermediate plate rigidly mounted on the hydraulic cylinder rod, connected by vertical columns with the upper 1T under-nail plate.

However, this chill machine could not be used for a single chill mold with different cavities, the axes of which are perpendicular to the plane of the chill mold, in one and the same casting. The number of permanent metal rods is limited by the amount of the chill machine, which coKpaiaaet the number of seats in the barrel or the number of cavities in the casting. These chill machines are of limited use for mechanically separating gates and feeders in various multi-chip molds.

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

cars..

This goal is achieved by the fact that the cocylock machine, containing a frame, mounted on the upper and lower podkokilnyh semikokili plates, rigidly fixed on the hydraulic rod of the cylinder, the intermediate plate connected by vertical columns with the upper tamikolous plate, is provided with an MTH hub for chromium and rods, and in

10 of the upper subcutaneous and intermediate plates are made through radial grooves, in which they are mounted on the intermediate plate with the possibility of axial adjustment of the sleeve.

The firm 1 shows a cocoon machine at the time of removal of permanent metal rods from a metal mold; Fig. 2 shows the upper subcutaneous and intermediate plates with bushings in one of the installation options for metal rods; in FIG. 3, view A and FIG. 2. .

The chill machine contains a bed 1, a top plate of the subcutaneous plate 2

25 and the lower one according to AА: the oxide plate 3, to which the upper and lower half-coconuts 4 are attached. The upper knuckle plate 2 is connected by columns 5 to an intermediate plate b fixed on the stem 7 of the cylinder of hydraulic water 8. On the guide columns 9 between the plates springs 10 are dressed. Plate 2 and 6 have through-shaped radial grooves I. In the grooves of the intermediate plate there are sleeves 12 for metal rods 13. The outer surface of the sleeves 12 has a thread on which nuts 14 are screwed, holding the sleeves in the grooves of the plate at the wrong height by rel sheniyu to the chill mold and at the desired distance from the plate center. The chill machine works as follows. After the melt has been poured with semi-coils 4 and solidified, the hydraulic actuator is turned on, and the hydraulic cylinder rod 7 moves along the guide columns 9 intermediate plate 6 with metal rods 13 installed in bushings 12. Springs U hold the upper plate 2 in the lowest position during metal removal rods 13 of semi-heels 4. With a further rise, the intermediate plate 6 by columns 5 raises the upper sub-hammer plate 2 with the upper semi-cocoon 4, the chills are opened. After removal from the casting chamber (not shown), the rod 7 of the hydraulic cylinder and, accordingly, the intermediate plate b are moved down and the half-heel is closed 4. Then the cycle is reversed. The grooves 11 in the intermediate plate b are designed to place the sleeves 12 in them with the ability to move in the radial direction during the installation of semi-coils 4 in the chill machine, and in the upper tuck-on plate for placing metal rods 13. The nuts 14 fix the sleeves 12 on the intermediate plate b with the possibility of adjustment along the axis of these sleeves and, correspondingly, metal rods 13; Such an adjustment makes it possible to remove even identical metal rods 13 from semi-coils 4 in series, which sharply reduces the force of the connector and, accordingly, the power consumed by the chill machine. The proposed chill machine makes it possible to manufacture castings with several cavities in a single chill mold or several hollow castings in a multi-piece mold, as well as to carry out sequential removal of cores, which reduces the thrust force of the hydraulic press and reduces the laboriousness of manufacturing the products. Formula of the Invention The chill machine, comprising a frame, mounted on the upper and lower hip plates of the semi-heel and rigidly fixed on the hydraulic rod of the intermediate plate, connected by vertical columns with the upper hog plate, differs from the fact that provided with sleeves for placing the rods a in the upper tamoil and in the intermediate plates are made through radial grooves in which the sleeves are mounted on the intermediate plate with the possibility of axial oh adjustment.
