CREAM FORM OF A LETTERING MACHINE

The well-known mold form of the filler machine is intended for casting letters of a typographic font, as well as set lines made up of individual letters.

This form has a rectangular casting cavity, two opposite walls of which are formed by side blocks with coolant channels, the third wall is a plate that pushes the casting letter, and the fourth wall is a transversely mounted block that can be reciprocated to open the cavity when ejected cast letters. The bottom wall forming the base of the cavity has an inlet opening that is offset to one of the side blocks.

In the proposed mold, the plate ejecting the cast letter, the transverse unit and the bottom wall have channels for the passage of coolant. In addition, the plastic ejecting the cast liguer and the transverse block are flexible hoses for supplying and discharging coolant, and the side walls are removable inserts for resizing the cavity. The presence of a water cooling system makes it possible to reduce the time it takes for the metal to solidify in the mold cavity and thereby speeds up the casting of a T.pugraph font.

On fpg. 1 shows the proposed form, a general view; in fig. 2 - the same, with partial

neckline; in fig. 3 shows a section A-L in FIG. one; in fig. 4 shows a section along B in FIG. 1; in fig. 5 is a diagram of ironing the coolant through the casting mold; pas figs. 6 - part of the mold with indication

coolant paths.

The casting form has a rectangular casting cavity bounded by two or more side blocks / and 2, a plate J, which together with the plate 4 forms a plate part and serves to eject the cast letter, and a transverse block 5. The bottom of the cavity is bottom wall 6. K. attached to the base of the outer side PL1GGY 7, 8 p 9 with the end

block W. With the sides of the plate, the base and the end block is rigidly connected intermediate plate 11.

The side blocks (and 2) are rigidly connected to the intermediate plate 11 and the side plates S

and 9 and ustapolepes at some distance from one another. Each side block is provided with interchangeable inserts 12 and 13 with solid and surface plins for greater resistance to wear. On each side block there are protrusions serving as supports and guides for the opposite side walls of plates 3 and 4. The side blocks and plates 3 and 4 are set so that the distance between the above sides, 1 and the surfaces and the wide part of the body of the plate part, slides between these surfaces was equal, but at least, to the maximum width of the shell. This allows the cavity to be resized by installing inserts 12 or 13. A1 between the side blocks in the intermediate plate V / there is an inlet for pouring a typographical alloy into the mold cavity 14. Two gating blocks 15 and 16, which form the upper part 17 of the inlet, are rigidly attached to the lower side of the noirechny block 5. The bottom part 18 of the inlet is in form 6 of the mold. In this case, the inlet is displaced in direction to one of the side blocks. The transverse unit 5 is installed with the possibility of reciprocating movement between the pressing unit 19 and the side units 1 and 2 from the actuator (not shown in the drawing) with a rod connected to the protrusion 20 of the transverse unit. The pressing unit is mounted on the side plate skid 21 21 and serves to open the shape strip when the letters are pushed out by plates 3 and 4. In the insert 13 there is a protrusion 22, and in the plate 3 there is a groove 23 for this protrusion. The plate 5 slides over the plate 4, which moves on the plate P. Both of the plates are moved between the side blocks in contact with the guides of the latter 24. The outer ends of the plates 3 and 4 are extruded between the side plates 5 and 5 and resting on the projection 25 of the intermediate liner) /. The cooling liquid is supplied to the inlet 26 and through the channels in the bottom wall 6, the intermediate plate 11, the side blocks 1 and 2, cross block 5 n plates 3 and 4, enters the form. The plate 5 and the transverse unit 5 have flexible hoses 27-30 for supplying and discharging the coolant. The cooling liquid exits the mold through the opening 31 in the base 6. After entering through the inlet opening 26, the cooling liquid first passes through the channel 32 along the base 6 to the section 33, rises but the channel 34 in the intermediate plate 11 and the side block I flows through the channel 35 of the insert 12 and descends through channel 36, located near cavity 14. Then, through channel 37, the liquid passes through side block 1 below. plates 3 and 4 into the intermediate plate 11 and further along the channel 38 along the side unit 2 and the insert 13 near the cavity 14. Through the channel 38 the liquid flows to the outlet 31. Simultaneously from the section 33 of the base 6, the liquid passes through the channel 39 along the base, and then along the vertical section 40 drips into the flexible hose 28, from where it passes to the lower part of the plate 3 and through the channel 41 to the cavity 14 of the form. The fluid returns along the plate 3 through the hose 27n through the channel 42 into the hole 43 at the base. On the other branch, the cooling fluid coming in through the inlet port 26, but channel 44 passes along the base to the side emit 7 and, but channel 45 to the flexible hose 29, the end of which is connected to the channel of the non-linear block 5. Then the liquid passes through the channel of the non-linear block, through the inlet 46 and drip 47, rises but the channel 48 to the gating unit 16 and goes to the horizontal channel 49 in the direction of the inlet 17 to fill in the printing force. Next, the fluid flows through the channel 50 through the transverse unit 5 into the gating unit 15 and through the channel 51 near the inlet. After that, but the channel 52 nostunat liquid in the transverse unit 5 to the flexible hose 30. Through the channel 53, the liquid is led to the outlet 54, located at the base. The casting is done as follows. The matrix with prints of typographic letters is installed in the cavity 14 all the way into the upper surfaces of the inserts 12 and 13 B of the side blocks 1 and 2. Before casting, the transverse block 5 is moved to the position where it forms the wall of the casting-floor 14. Top and bottom 17 and 18 The outer hole is aligned in the vertical direction. Plates 5 and 4 are moved away from the transverse block to the required distance. The molten metal is poured into floor 14, where it cools and solidifies, after which the non-sprung block 5 is moved away along with the gating blocks 15 and 16. Then the plates 3 and 4 are moved across the cavity 14 and extruded the cast letter through the open side of the cavity. The subject matter of the invention 1. The molding form of a spinning machine, having a rectangular casting floor, two opposite walls of which are formed by side blocks having channels for passing coolant, a third wall of the cavity is formed by a plate that pushes the cast letter reciprocating movement to open the floor and eject the ejected casting, and the wall that forms the base of the cavity has an inlet the hole is offset to one of the side blocks of the casting productivity, the plate, the ejection molded letter, the transverse block and the bottom wall have channels for the passage of coolant. 2. The casting mold according to claim 1, characterized in that the plastic extrusion cast

Fig. / Letter, and the transverse unit has flexible hoses for the supply and removal of coolant. 3. A casting mold, characterized in that. that the side blocks are provided with removable inserts for resizing polostp.
