Abstract

Usage: casting parts in a chill mold. SUMMARY OF THE INVENTION: the machine consists of a drive, a leading section 2, a tension section 3, a number of intermediate sections 4, lamellar chains 5, tensioned on the leading 6 and driven 7 sprockets, lower half-coils 8, mounted on the pull chains of the upper half-coils 9 connected to the lower ones with a possibility of rotation and provided with rollers 10, a guide 11 located around the sprockets 7 and its inner surface is described by the expression p (-pi}. where p is the distance of the sprocket axis to the outer surface of the roller mounted on the upper chill mold; pi - otherwise position above the upper branch of the plate-like chain; pi - value under the lower branch of the plate-type chain; y - angle, radian, (p (pi / pi - p) -g above the upper branch of the plate-type chain; y (p-pi ) + 1 -n under the lower branch of the plate chain chains, and the axis of the rollers are located at the free edge of the upper half of the chill mold. 4 ill.

Description

At the point O - the origin of the angle p (the increase in the angle occurs clockwise). In a specific example, p is 420 mm, pi is 660 mm.

The distance between the mouth of the sprocket axis and the outer surface of the roller mounted on the upper chill mold as a function of angle f is shown in the table for a specific example.

In the initial position at point a, the roller 10 of the upper half of the chill mold smoothly enters the guide (at point a) when the sprocket 7 rotates counterclockwise and gradually approaches the lower half of the chill mold. Upon reaching point b, the chill mold is completely closed. Due to the fact that the axis of the rollers is located at the free edge of the upper half of the chill molds, the shoulder pressing force of the roller against the guide is two times greater than in the prototype, therefore, with equal moments of pressing force and gravity in the proposed device, the pressing force is twice less than in the prototype, therefore, wear is less, durability is more.

Figure 1 shows the device, a General view; figure 2 is the same, plan view; in Fig.3 is a section along aa in Fig.1; figure 4 is a section of figure 2.

As can be seen from these figures, the machine for casting parts into a chill mold with a horizontal connector consists of a drive 1, a leading section 2, a tension section 3, a number of intermediate sections 4, lamellar chains 5, tensioned on the leading 6 and driven 7 sprockets , the lower halves of the chill molds 8, mounted on the traction chains, the upper halves of the chill mold 9, connected to the lower ones with the possibility of rotation and provided with rollers 10 of the guide 11. The guide 11 is located around the sprockets 7 and its inner surface corresponds to the formula

The proposed device operates as follows.

When the drive motor 1 is turned on, the drive sprockets 6 begin to rotate and the lamellar chain chains 5 with the chills 8 and 9 are driven. On the lower branch of the lamellar chain chains 5, the upper halves of the chill mold 9 hang vertically. When approaching the guide 11 (at point a), the roller 10 smoothly approaches the guide 11 and gradually presses the upper half of the chill molds 9 to the lower 8. At point b, the chill mold is assembled. The chill mold is poured, and the mass of the upper half of the chill mold 9 is selected so that additional loading is not required to avoid lifting during pouring. When the leading wall is bent around, the upper halves 9 under the action of gravity are opened, they hit the adjacent lower front half 8. leading to knocking out the castings. During further movement along the lower branch, the chill molds are blown with air to cool through the air nozzle 12 and stained with a spray gun 13.

The use of the proposed device allows to fully automate the production of castings without rods.
