Description

In the known multi-position feed-through molding machines used to automate the manufacture of molds from conventional sand mixtures, model plates are moved using a pusher system along a rectangular path closed in a horizontal plane.

Such molding machines have many actuators, are COMPLEX to be cumbersome in their design.

In the construction of the proposed multi-positional molding machine of model-type movement, model plates move from a position to a position along a rectangular path closed in a vertical direction, which simplifies the design and makes the machine more productive.

Pa drawing shows a schematic vertical section of the described molding machine.

The frame of the molding machine consists of an upper bed / and a lower bed 2, connected by columns 3 and 4.

In the upper frame there is a drive edge roller 5, a servant for transporting model plates 5 and 7 from position to position. An edge roller conveyor drive consists of a cylinder 8 in which a piston-rail moves, engages with bristles 9, sitting on the same shaft with two asterisks 10 connected by a chain with small asterisks sitting on the shafts of the edge-rolling roller table 5. Edge roller tables //, 12 and 13 are located on the same bed. Each edge of the roller tables is a bar with rollers fixed on it, having two guides and a membrane pneumatic pusher that opens or closes the edge roller table at the right moment.

Edge roller tables //, 12 and 13 do not have a drive. The flasks are transported over them by a remote pusher, which is a frame consisting of two longitudinal bars, 14, connected by crossbars 15, moving but not on the bed / on rollers 7b. On the longitudinal bars 14, two toothed racks 17 are included. in engagement with the bristles 18, sitting on the same shaft with the bristles 19, driven by the Nick-rail, moving in the cylinder 20. On the longitudinal th 14 there are hooks 21, which move the box to the left when moving the pusher to the right.

The molding molding described has three positions A, B and B. In position L, the mold box is placed on the model plate and backfilled by molding mixture with its simultaneous compaction (sand-blowing process or shaking). At position B, the final compaction of the molding sand is made and the model is drawn. At position B, the turning and assembling of forms takes place.

Empty flask 22 is supplied by a remote pusher to position -4. At the same time, the model plate 6, together with the lifting table 23, rises upwards and takes the flask 22, which sits on the plate with the help of ordinary conical slopes, and the position of the flask is fixed by stops. After settling the flask on the model plate, backfilling it with molding sand and pre-compaction, the roller table 11 closes and the box 22 moves with the model plate 6 from position L to position B, lifting table 23 is lowered and it moves from position B to other model plate 7. The flask 22 at position B is subjected to pressing, during which the edge roller 12 moves apart and, during the pressing process, the model plate 6 passes freely through it, sits on the raised table 24, and the flask hangs on the roller table ( happened um prot buckle arrangement) and moves to a position B. The table 24 with the pattern plate 6 is lowered down and plate peremeschaeggs to position A by means of the roller conveyor 5.

At position B, table 25 rises to the level of an extended edge roller table 13, as a result of which flask 22, moved to position B, falls on roller table 26 of table 25 and is clamped into tilter 27. Table 25 is on and half the form is turned. The edge roller conveyor 28 of the table 29 is brought under it, which, when it is lowered down, places the webbed bottom half-form on the roller table 26 of the table 25.

The next flask, moved to position B, will be a half-form of the top. She does not turn over. The edge roller conveyor 28 of the table 29 is brought under it, which, when it is lowered down, pairs the upper half-form with the lower one with the help of conical straps. The smoothness and accuracy of the pairing of the half-molds is ensured by the fact that they can move relative to each other on mutually perpendicular roller tables. The two molding masks described can work in pairs, for which they must be connected by a edge roller table, which is a continuation of the roller table 28.

The described multi-positional molding machine of the type through passage is simple in design and gives a large productivity.
