Description

-2-exposition of the vizon of the invention

The invention is based on the technical problem of providing a solution for an automatic device for forming hollow figures of two-part molds and returning the empty mold halves to the casting station of the hollow-figure plant with the working phases arranging the closed two-part molds, releasing the molded articles in the closed two-part mold, Separation of upper mold part and lower part, leading away the upper mold part, emptying of the lower mold part, clocked, ordered, pairwise merging and returning the empty mold halves to the casting station of the hollow molding plant from mold folder, detaching, cover, turning, return station represent. According to the group supplied, closed, filled, two-part molds are released by means of time-shifted moving pushers for further transport. After reaching the insertion position fixed with stop, the filled, two-part form is pushed by slide on two resiliently mounted strips. Elastic deformation of the mold by means of a ram supports the residual detachment of the shaped hollow figures from the mold half walls. When fed to the Abdeckelstation the closed, two-part mold is positioned by clocked on and disengageable locking pin, first raised by the recess in the lower mold part by means of the beginning of the mold top part plunger unilaterally and fixed in the upper position by means of spring-loaded locking lever. Thereafter, with a second plunger with the same approach, the opposite side of the Formenobertoiles pushed up to the horizontal position and pushed over the spring-loaded locking lever on a rigid support bar, this is the filled mold base by rigid hold-down, which begin at the edge of the mold incorporated recesses , secured against lifting.

The upper mold part is inserted by means of a slider on the same level in a swing frame, pivoted with it up to 180 ° and stored gravitationally on a return conveyor belt in the required feed position to the casting machine. The capped, filled with detached items mold bottom is fed after disengagement of the locking pin in the turning station.

After reaching the insertion position fixed with stop the filled mold base is inserted by means of slide in two opposite turning rails, there arrested from both sides with a spring-loaded ball bearing in the recesses of his front pages and by synchronous rolling of the turning rails supporting gears by 180 ° on each rack, gravitationally unloaded from articles on the conveyor belt. The combined turning and lowering movement of the turning rail makes it possible to push out emptied lower mold part by means of a slider against its previous insertion direction from the lowered turning rails to a lower lying feed belt. The emptied mold base is brought during its supply to the return station by stacked opposing belt conveyor in its required feed position to the casting machine.

The clocked pairwise ordered return of the mold tops and the emptied mold bases is realized by pushing out a deflated mold bottom from a formed mold bottom block on the pulse of falling on the same return belt mold shell and thus closed the molding cycle. The transport of the closed molds and opened mold halves by means of continuously moving webbing conveyor, all working organs (slide, plunger, locking pin, swing frame, turn rail) are driven by means of pneumatic cylinder to the triggered by the incoming pulse form.

embodiment The invention will be explained using an exemplary embodiment.

Fig. 1 shows the classification of the automatic molding device between production plant consisting of casting station. 1

and cooling paternoster 2, and the further processing processes such as Stanniolieren 6 u. ä.

According to Fig. 2 and 3, the groups supplied, filled, two-part molds 7 after leaving the Kühlpaternosters 2 clocked first in the mold folder 11. In this case, two locking slide 18 stop the movement of the second and

third mold 7, while the first mold 7 immediately slips on a webbing conveyor 17. With a time delay, the locking slides are lowered and forms 7 are fed to the belt conveyor 17.

According to Fig. 2 and 4, the mold 7 after reaching the fixed stop with insertion position by means of slide 19 on two spring

fastened strips pushed on. By elastic deformation of the mold by means of two push rods 20, the separation of the shaped hollow figures is supported by the mold half walls. The moving through the slide 19 mold 7 transports the mold located on the strips 7 on a lower belt conveyor 17th

According to FIGS. 2, 5 and 6, the mold 7 is supplied to the cover station 13 and positioned by means of locking pins 27. By Hubstößel 25 is the upper mold part 8 through the recess in the filled mold base 9 first on one side of its edge

lifted and pressed on two spring-loaded locking lever 23. With the same approach, the opposite side of the

Mold upper part 8 pushed up to the horizontal position and pushed onto a rigid support bar. Two rigid hold-down 26 prevent the lifting of the lower mold part 9. By means of slide 19, the upper mold part 8 on

pushed the same level in the swing frame 28, with him up to 180 "and pivoted on a lower

Gurtbandförderer 17gravitatively filed. After disengagement of the locking pin 27, the lower mold part 9 of the turning station 14th

fed.

According to Fig. 2 and 7, the lower mold part 9 after reaching the stop position fixed by means of slide 19 in

two opposite turning rails 21 inserted. A locking device 22, consisting of a spring-loaded

Ball bearing, locks the lower mold part 9 in the recesses of its end faces. By rolling two, the Wendeschionen

supporting gears by 180 ° on each rack, the mold base 9 is gravitational of articles on a

Figure conveyor belt 16 emptied. A slider 19 pushes the rotated, lowered and empty mold bottom 10 against its previous Insertion direction from the turning rails 21 on a webbing conveyor 17. The required feed position of the Mold lower part 10 to the casting station 1 is by tilting the lower mold part 10 to a lower level

realized opposite webbing conveyor 17.

According to FIGS. 2 and 8, the ordered pairwise return of the upper mold parts 8 and lower mold parts 10 takes place in the Rückführstation 15. It is due to the impulse of a higher belt conveyor 17 on the Mold return belt 4 falling upper mold part 8 a lower mold part 10 au3 a jam by means of slide 19 on the Mold return tape 4 pushed and transported to the casting station 1. Thus, the molding cycle is closed.
