Description

The invention relates to devices for the production of products from polymeric materials and can be used in the woodworking industry in the manufacture of products from polymeric materials for MHfKdft furniture, as well as in other pastures of national economy. A known installation for the continuous manufacture of products from polymeric materials, comprising half-molds moving around an annular support, interlocking with a subsequent half-form f | . The disadvantage of this installation is that dynamic shocks occur when the half-form is moved from the unloading position to the closing and loading position, which can cause damage to individual components and shorten the service life of the installation. The closest technical solution is a device for continuous production of products from polymeric materials, containing a rotating disk with molds, an interlocking and disconnecting device, mechanisms for loading and unloading press molds 2. The disadvantage of this device is that it has large dimensions and a low manufacturer. The aim of the invention is to measure the dimensions and increase the productivity of the device. The goal is achieved by the fact that the device is equipped with additional, below, disk, images of aHHbiNs from separate platforms with molds placed on them, and having rollers, interacting with a copier surface. FIG. 1 shows the proposed device; in fig. 2 - section A-A of FIG. one; in fig. 3 - section bb of FIG. 2. Installation of products made of polymeric materials contains a rotating disk1 fixed on a fixed axis 2, an electric motor 3, a belt drive 4, a gearbox 5, a conical pair 6 and 7 and a cylindrical pair 8 and 9, which communicate the rotational movement of the disk 1, on the surface of which there is a mold 10, representing the top Russian installation. Loading and unloading mechanisms are as follows.

On the cylindrical part 11 of the rotating disk 1, the guides 12 are fastened to the lower part, between which there is a slide 13, which provides additional movement (direction) of the carriage 14. On the platform 15 a mold 16 is fixed. In the lower part of the slide 13, the chassis 17 is fixed. terminating with a movable arm 18, which allows the wheel 19 to rotate around the chassis 17 with a roller 20. The trolley 14 is fixed in the extreme positions. Mold 16, located under the disk 1, form an additional Rus. The copy surface 21 is movably secured to the finger 22. On the copy surface 21, the finger 23 is rigidly fixed, by means of which the rod 24 of the pneumatic cylinder 25 deflects the copy surface 21, ensuring the exit of the lower rus molds 16. Copy surface 26 provides entry of molds 16.

The closing and disconnecting devices comprise a shoulder 27, which serves to pivot the lock 28, which grips the finger 29. The stop 30 limits the rotation of the lock 28 seated on the axis

31, on which springs are mounted

32, covered with a nut 33. The device operates as follows.

When the disk 1 is rotated, the molds 10 installed on it are traversed a certain distance. At the moment when the mold 10 passes through the mold removal area and the mold is filled with components, the operator turns the finger 29 away from the lock 28, opens the mold 10, after which the finished product is selected and the corresponding components are poured into the mold to obtain the next foamed product. Next, the operator closes the mold 10. With the further passage of the molds of the technological cycle, a polymerization process occurs, ending by the moment when the operator serves the lower rus. After mold service

10, the upper operator sends a signal to the pneumatic cylinder 25, the rod 24 of which, the exit from the pneumatic cylinder 25, deflects the copy surface 21, on which the roller slides

20, and the cart 14 begins to leave

from under the disk 1. After the mold 10 has been serviced, the coping surface 26, in contact with the roller 20, ensures its insertion

Under the disk 1. By the time the lower russe service ends, the process of polymerization of products on the upper rus ends, then the cycle repeats.
