Molding tool for producing mold rial from the mold cavity between the pieces made of elastic material, with the space formed in the two parts being able to flow.
Walls of the molding tool bores can also be the outer end face of a recess into which the inserts are fitted, the set can be machined in such a way that during molding it is characterized in that a flower is produced for the production of the middle part, while the ropes from wing or leaf-shaped projections tenwand of the insert can be processed so that on the surface of the moldings the side surfaces io a cavity between the insert and the wall of the inserts towards the mold cavity Ausneh- the bore is formed with which have thin flowers. · Ten leaves when shaping, which result in the middle 2.

The only ones required for this in the case of drilling in the walls of the molding tool, drilling is one of the machining processes gen are provided, are fitted into the inserts. cylindrical hole in the shape and milling It is known to have a patterned surface 30 surfaces or grooves in the cylindrical insert,
provided object by means of a molding tool- The molding tool according to the invention is to produce, in its cavity surface particularly advantageous in the production of baths, the caps and hot water bottles desired on the surface of the object can be used,
th ornaments or patterns are incorporated. Fer- The invention is based on an embodiment It is already known to explain objects in more detail by means of an example. Produce molding tool, of the form of the F i g. 1 and 2 show a section through the Flat bores go out into the inserts fitted form surface in which there is a cylindrical Bohsind. The outer face of each insert is located with its central axis perpendicular to the represents a part of the mold surface. This forehead mold surface stands. decorative patterns are incorporated into the surface. By 40 F i g. 3 shows a plan view of the use after this measure it is possible to time the pattern of FIG. 1.
to change time by changing the inserts. 'In Fig. 1, the insert has the shape of a cylinder The object of the invention is to make the production of the same diameter as the cylindrical molds has drilled holes in the mold surface that are too twisted for certain objects. In simplifying and the cylinder is easier to remove from the mold to the extent of its circumference. worked to create three beveled surfaces The problem is solved by the fact that are. These inclined surfaces are arranged in such a way for the production of wing-shaped or leaf-shaped vor that the insert has an im at one end Cracks on the surface of the briquettes the side. essential triangular cross-section and a run surface the inserts towards the mold cavity recess 50 has the cross section at its other end, have statements. as shown in FIG. 3 »can be seen. The recesses can be cylindrical in the case of the embodiment according to FIG sentences divided in the form of several spread over the scope of use. The inner part (A) has the shape of surfaces. of a cylinder that. at one end with a The insert can also be designed in an annular, the 55 strong bevel. In the beveled The part facing the mold cavity and a second area are incorporated into it, and surfaces are machined into it the part having recesses be divided. these areas are engraved with veining patterns The invention enables the shaping to correspond impressively to the veining of a leaf. The other full of patterns without any difficult work. Part (ß) has the shape of a ring. A face-making of the mold cavities are required. So 60 surface of this ring closes flush with the surface of the can for example long from the surface of the mold cavity. The sheet-like projections protruding from the other end face of the briquettes is designed conically in such a way that they can be poured off, simply by adapting surfaces or inclined surfaces of the inner part (A) . Grooves along the outer surface of a cylindrical * This design results in between the drical insert, whereby the two parts allow a number of thin, flat hollow cylindrical inserts in a cylindrical bore which fits at an angle to the axis of the cylinder will. There can also be more bores in each bore and the inserts that are actually part can be arranged. For example, mold cavity are in direct connection.
