Description

For the manufacture of landing glasses from a gypsum mass hardened in molds, a machine is proposed consisting of rectangular through molding cells, fixedly fixed in the upper board of the table. A hollow box is used in each cell, which serves as a molding core and is installed in the cell when casting plaster mass. After the casting is hardened, all the boxes, fastened with their rods to the moving platform, rise up, pulling out the hardened product.

In FIG. 1 shows the top view of the machine; FIG. 2nd vertical section; FIG. 3 and 3 are vertical sections of the molding device; FIG. 3 is a section along the line CD in FIG. 3; FIG. 4, 4 and 5 are vertical sections of the molding device; FIG. 6 - top view of the comb; FIG. 7 shows a section along the line AB in FIG. 6; FIG. 8 is a front view of a clip with a seat cup inserted into it; FIG. 9 - the same, from above.

The proposed machine for the manufacture of landing cups consists of a table / (Fig. 1 and 2), a lifting mechanism 2, a movable platform 11, a molding tool 3 and two combs 4 (Fig. 6 and 7).

The table / has four legs, fastened together with each other, bars 5 (Fig. 2) and supporting two boards 7.

Lifting mechanism 2 composition. The lead screw 8 (Fig. 2), the flywheel 9 (Fig. 1) and the nut 10 are moved. The movable platform // consists of a board 12 (Fig. 2) and five spacers 13.

The molding device is formed of 400 identical devices 14 consisting of molding through cells 75 fixedly mounted on the board 7, into which the hollow boxes 16 are skipped (Fig. 3, 3, 3). The latter are fastened with plates to the ends of the rods 17, passed through the tubes 22, connected to the rods by means of latches 23 and used for insertion into the molding cells 15 attached to the designated tubes of the pistons 21 with flannel gaskets (Fig. 4, 4 and 5).

For simultaneous removal of products from the boxes 16, a comb is arranged between rows of comb cells 75 (Fig. 6 and 7), consisting of a row of parallel-arranged teeth 24, equipped with longitudinal flannel 25 and metal 26 plates (Fig. 4). These teeth serve to alternately fit one or the other of the transverse intercellular rows in order to unload the items raised on the mold boxes 16 that have hardened after the removal of the products, as well as to alternately clean and lubricate the side faces of the boxes.

For the purpose of automatic lubrication of flannel piston gaskets at the bottom of the molding cells 75, tanks 28 are installed (Fig. 3, 3, 3).

When working, the machine, the molding device of which is in the position / (Fig. 3), is filled with a liquid mass, then smoothed by a wooden board. After five to six minutes, the moment of mass collapses. By turning the handwheel 9, the lead screw 10 is lowered, and with it the movable platform 72 with the rods 77. Boxes 76, tubes and pistons go down along with the rods. The boxes are detached from the mass that remains in place, since the walls of the cells in which the mass is placed are narrowed downwards (Fig. 3, position //). Here, thanks to the pegs 18, holes are formed in the top of the lining in the bottom of the glasses, through which air penetrates into the inside of the glasses, which prevents the bottom of the glasses from breaking. The flannel gaskets of the pistons are immersed in reservoirs 28 with a lubricant installed at the bottom of the cells 75 and interconnected by holes 20 in the walls (Figs. 3, 4 and 5). The machine is left in this position for three to four minutes, depending on the composition of the mass. The reverse motion of the flywheel 9 raises the platforms, rods, tubes and boxes. Boxes and pistons income m to solidified mass and lead it up. In this case, the flannel gaskets of the pistons lubricate the inner walls of the cells. When the latches are placed on the tooth, the tubes 22 are separated from the rods 77, while the tube hangers 31 abut against the upper board 32 of the table (Fig. 4. With the rods 77 continuing upward, the tubes and pistons remain in place, and the rods with boxes 16 continue move up to the position of / (Fig. 4). The entire hardened mass is supported by the boxes 16. Having stopped the rotation of the flywheel 9, the combs moistened in the lubricant are pulled from both sides by the edges. The combs move along the guiding strips 33 (Fig. 1 and 2), and the middle cutout mi 55 along the planks 34. The teeth of the combs 24 lie on the walls of the cells 75 (Fig. 4) .The reverse movement of the flywheel 9 lowers the rods 77 with the boxes 16 down, while the two walls of the boxes are greased with flannel gaskets of the dies.

The manufactured cups remain on the combs. Upon further downward movement, the rods 77 are connected to the tubes 22 with the help of latches, and together they move to the initial position / (Fig. 3). All glasses on the combs are covered with a lattice box. Combs hooks fasten with the walls of the box; The box is turned over and removed along with combs from the machine. Thereafter, the dies are separated from the crate, the boxes on the other side are pushed over and the boxes 16 are moved between the teeth of the 24 dies by rotating the flywheel 9 into one and the other side, lubricating the other two sides of the boxes.

Thus, within an hour it is possible, depending on the QT composition of the mass and on the dimensions of the machine, to produce from four to six batches, i.e. from 1600 to 2400 glasses.

Before putting on the crate, each row of glasses can be enclosed in the clip (Fig. 8 and 9), thrust it onto the bottoms of the glasses, and after that put on the crate and remove the cups from the machine. Conclusion of glasses in the cage is necessary for the further mechanization of the transfer process.

To make the cups of a different height, the latches are pressed, the tubes with the piston lift up and the latches are inserted into the second holes in the rods (Fig. 4, position //), and then put on the rods 77 of the box 76 of the desired size. The whole process of dressing is as described above.

The machine can also serve for the manufacture of lids to the glasses. For this purpose, the plates 18 are unscrewed (Fig. 1), and figured plates 37 (Fig. 5) are put on and screwed onto boxes 16 and screwed onto rods 77. By turning the flywheel 9, boxes 16 are installed in such a way as to obtain covers of the desired thickness, and then cast.

The subject matter of the invention.
