Steel mold for the production of τοη cast bodies «

809807/0165

The invention relates to steel molds for molding _; (PIaOieren) of greetings / in the production of base bodies, such as walls,,! Tunnels, and arches. The steel mold according to the present invention _: has the advantages that it can be used to produce precise and smooth rubber surfaces, that it is easy to handle, that it enables short set-up and dismantling times and that a special one Shaping and high mechanical strength improves the resistance to casting pressure and twisting «

In general, a steel mold is used for forming, from Gfuß the Demands made, light, torsion-free and easy in the Handling too s a. Recently, metal molds are used to shape Greeting instead of wooden shapes came into use. The divorced " like steel forms have become known. With all these stani £ ~ forms, form and associated brackets are separated and when ^ to- · They are aligned by means of guide pins and clamped together with brackets. Become a Zjjis ammenkl amm er η Clamp pins pushed through holes made in the outer frame two adjacent shapes are provided. In the cases in which the named outer frames touch over the entire surface, the holes provided therein are therefore congruent the pins inserted through these holes have play in the Direction of introduction. That is, the following defects occur If the pin can move in the guide direction, is it is possible that it will be pierced, ^ n ^ although ... just then, if: the long frame of the two shapes did not make perfect contact with each other, so that it is probable that the merged Shapes do not align exactly. When pins and clips " are separated from the form., they need to be used in case> that the

Shapes are joined together in an inaccessible place should be brought there separately from the forms. Such shapes are not only inconvenient to use but also difficult assemble.

The subject of the present invention is a steel mold for forming castings, the brackets are associated so that the damage and the danger caused by the clips falling off are prevented and which are assembled very quickly and easily can be.

The present invention also includes a steel mold for molding castings in which the outer frame is not flat but W-shaped is formed so that the mold has a great resistance to molding pressure and distortion.

The present invention further includes a steel mold for molding of cast iron that can be properly aligned and easily clamped together ·.

In addition, according to the present invention, there is a steel mold for molding castings provided, which can be generally used for various structures, which has great rigidity, easy to is easy to handle, has few supports and is very easy to transport and store with the accessories.

The invention is explained with reference to several figures. Show here «

The steel mold shown in Figs. 1 to 3 for forming castings is used to produce a flat surface of a cast body.

A clamping arm is arranged rotatable about the axis of a Terbindungsstange namely rotatable either together with the Terbindungsstange, or alone. The tie rod is pushed through holes provided in the outer and middle frame of the steel mold * It can move axially a certain length until it hits two sides.

It is connected at the edges on the outside to the outer frame 2 and the end plates 22 »The required Number of holes 6 is made in the concave part 1 of the outer frame. A clamp arm 8 is on a connecting rod 7 applied and represents a bracket. The connecting rod 7 is through a bore 10 in a metallic holder 9, which is attached at the lower end to the cover plate 4 and pushed through a hole 6 in the outer frame (see. Fig. 6), so that the bracket is attached to the steel mold. This is how the Clamp arm 8 in contact with the outer frame 2 or the metallic Bracket 9ι so that the Yerbindungsstange 7 against pulling out from the holes 6 and 10 is protected. The steel forms A and Bi which are connected to the inner angle steel form are of the kind shown in FIGS. 1-3 are.

To assemble the steel form to form an interior angle, the holes 6 in the outer frame 2 of the interior angle steel form and the steel form A or B are first (see 7 in. The hole in which the other steel shape is inserted. The clamping arm 8 is then pivoted about the axis, der.Verbindungsstange, so that the concave parts of the outer frame. . to be bracketed together »In this way wiyd, di§ _; Position to each other t fixed with the connecting rods 7 and it w ^ rdieri.di-e; Steel molds T ₁ securely connected by means of the clamping arms.

Steel forms are connected by means of the clamping arms. Fig. 5 shows like the interior angle steel shape and the steel shapes A and B by means of the connecting rods and clamping arms are clamped together «,

! In the event that the interior angle of the construction is not right-angled can be proceeded according to the invention if the inner angle of the end plate is made exactly equal to the inner angle will. Furthermore, the invention can also be used when the interior angle part is arcuate. Likewise with a steel mold for external angle parts for forming castings for cast constructions (see Fig. 8 and 9), if the external angle is right-angled, an outer frame of L-shaped end plates 22 and outer frames 2 are formed. Each of the outer frames here has a hat-shaped, concave part 1 in the middle and protruding horizontally Flanges 11 on the top and bottom. They are located inside the edge of the rectangular curved cover plate. as well as in the steel mold for interior angle parts, in the concave part 1 of the outer frame is the required number of holes attached; In addition, a clamp arm 8 · on a connecting rod-7 provided and forms a bracket with it. The connecting rod 7 is through a hole 10 in a metallic, Bracket, which is attached at the lower end to the cover plate 4, and a hole 6 pushed in the outer frame so that the bracket is connected to the steel mold. Fig. 9 shows the external angle steel molds A and'B as connected by means of the brackets
