Description

The invention relates to the manufacture of foam products, in particular polystyrene foam, and can be used in many industries.

The purpose of the invention is to improve the quality of manufactured products by eliminating their damage.

Fig. 1 shows a device, a section; FIG. 2 is a section A-A in FIG. 1; FIG. 3 is a view B of FIG. 1; in fig. 4 is a view B in FIG. 3; FIG. 5 is a section on the HGD of FIG. four.

A device for producing expanded polystyrene products contains a power unit 1 (press) for smith: an animated form block consisting of an upper half-mold 2 and a lower half-mold 3. On the upper half-mold 2 there is mounted a mechanism for gripping the finished products in the form of installed on opposite sides and 4 rotatable levers 5 and 6 with bars 7, on which spikes 8 are fastened to grip the products, are fixed between the barbell. The lever 6 is connected to a lever 10 which is spring-loaded relative to the pivot bracket 9. The bottom half-mold 2 is mounted on the ejection plate 11. On the plate 11, on opposite sides of the half-molds, unequal high thrusts 12 are mounted on which adjustable stops 13 and rails 14 are located to turn the gear wheels 15, which push or pull the pushers 16, which are mounted with the ability to interact with the corresponding rotary levers 5 and 6, the ejection plate 11 is moved by the ejectors 17 away from the drive. Mechanisms 18 for filling the form are pre-installed on the upper half-form and have 5 foam foamed polystyrene. The device is equipped with a mechanism 19 for unloading finished products 20 in the form of parallel-lying at a distance, larger dimensions of the half-form and having a horizontal section for unloading products and a vertical section for. two endless chains 21 connected between each other by pins 22 on one of the sections, the length of which corresponds to the length of the finished product.

An actuator 23 is mounted for moving the chains 21 and a locking 24 is used for selecting the product. In addition, a manifold (not shown) is provided for supplying steam and water.

The device works as follows.

Upon completion of the sintering process of expanded polystyrene, the mold opens,

and the upper half-form 2 rises up a distance greater than the stroke of the ejection frame by 40-50 mm and takes up an intermediate runner,

0 Then, the ejection plate 11 rises, and the product 20 is again partially inserted into the upper mold half 2. Together with the plate, rods 12 are lifted, which with stops 13 act on

5 slats 14. Slats 14, rotating the gears 15, set in motion the plungers 16. In the extreme upper position of the plate 11, the right plunger 16 moves the swivel lever 5 with spikes

0, 8, and since the lever 5 is connected by a rod 4 with a pivoting lever 6 with spikes 8, it moves the bar to the distance at which they pass an unstable position and with

5 spring-loaded lever 10 closes the strips 7, which, with their spikes 8 (02 mm), engage the product 20.

The angle of rotation of the levers is designed so that the strips of 1-3 mm do not reach the product in order not to leave an imprint on it and not to spoil the presentation.

The ejection plate 11 in the upper position acts on the position sensor, with the result that the movable plate of the power body 1 together with the upper half-form 2 rises to the extreme upper position and acts (1, impinges on the position sensor, the drive 23 of the chains 21 turns on, while the pins 22 enter t into the space between the half-and are located under the product 20. After that, the plate 11 vip-alky-ni falls down, the pushers 16 begin to move, and the left pusher extends, spreading the swivel levers 5 and 6 with strips 7 and spikes 8 and they fixed uyuts

(j in the diluted position, and the right pusher 16 is drawn in, freeing the way for the upper half-form to move downwards.

Then the unloading mechanism returns to its original position, with the pins moving first in a plane parallel to the plane of the half-form connector, then, bending along with the chains
