Description

The invention relates to devices for the manufacture of articles from molding compounds.

The purpose of the invention is to improve the quality of products by eliminating gaps between the sides, facilitating the process of stripping and improving reliability.

FIG. 1 shows the installation, general view ;, FIG. 2 is a view A of FIG. one; FIG. 3 is a view B in FIG. one; in fig. 4 — node I in FIG. 2; in fig. 5 is a view of B in FIG. 1 (locking device); in fig. 6 is a view of FIG. one; in fig. 7 is a section d-d in fig. 6; in fig. 8 is a section E-E of FIG. one; in fig. 9 — node II in FIG. one; in fig. 10 is a section of an LF in FIG. 9, in FIG. 11 is a section through AND-FIG. 9; in fig. 12 is a section C-C in FIG. eight; in fig. 13 is a node III in FIG. one; in fig. 14 is a section LL in FIG. 13.

The installation for molding the ventilation units comprises a base 1, a vibro-cabinet 2 mounted on the base 1, a pallet 3 mounted on the base-1 and mixed in a vertical plane by means of a hydraulic cylinder 4, hingedly interconnected sliding sides 5 and a lock 6 for fixing the sides 5 in a standing position.

The installation is equipped with a stand 7 mounted on the base 1 with guide rollers 8 and a limit switch 9, a locking device 10 pivotally connected to the stand 7, and stops 11 mounted on the sides 5 and guide brackets 12. The lock device 10 is made in the form of a lever 13 with a roller 14, provided with a spring-loaded retainer 15 with a ruler 16 in contact with the limit switch 9. The lock b is hingedly connected to the hydraulic cylinder 4 and is designed as a shtangi being moved along the guide rollers 8 and provided with a roller 14 stop 17 and in contact with the stop 11 sides 5 brackets 18 with clamps 19, in contact

with guide brackets 12. The guide brackets 12 are made in the form of a split cone, the flat side of which is parallel to the beads 5. In the closed position, the spring-loaded clamp 15 enters the bracket 20 with a groove.

The installation works as follows.

The sides 5 are opened, while the hydraulic cylinder 4 tons is not followed by the lock 6 rod, which is raised upwards in the direction of y. 8 pillars of the rack 7. In this case, the clips 19 of the brackets 18 exit from the guide holes of the brackets 12 and the locks open 6. With a further rise of the stopper of the locking device 10, the brackets 18 slide along

0 the inclined surface of the stops 11 and tear off the beads 5 from the concrete surface. Zat.m hydraulic cylinders 4 raise the pallet 3 with the product. To close the flanges 5, the rod of the hydraulic cylinder 4 goes down, after which the clips 19 of the brackets 18 enter the guide holes of the brackets 12 and the flanges 5 shrink. To prevent gaps between the flanges 5 arising from the installation vibration, turn the locking device 10 by 30 °,

0 fix it in this position and do not allow the lock 6 to move upwards. At the same time, the locking device 10 presses the limit switch 9 with the ruler 16 and the installation control circuit opens, which prevents the locking device 10 from breaking. the locking device 10 to the neutral position.
