It is a figure which shows the state in which the slider is further sinking in the supply opening arrange | positioned correspondingly.

  In FIG. 1 to FIG. 6, a die casting machine is shown in two embodiments 1 and 10. The die casting machines 1 and 10 are for producing a metal casting 2. For this purpose, the die casting machine 1, 10 has a die casting mold 3, which has at least one cavity 4, which defines the contour of the casting 2.

  The die casting molds 3 of the die casting machines 1 and 10 include at least one fixed first mold part 5, at least one second mold part 7 movable along the guide column 6, and a second mold part 5. And at least two mold side portions 8 and 9 that are movable relative to each other in the lateral direction with respect to the movement path of the mold portion 7. The fixed first mold part 5 is firmly attached to a machine plate (fixed platen) 11 of the die casting machine 1, 10. The movable second mold part 7 is held by at least one hydraulic cylinder 12 which acts as a moving drive. The hydraulic cylinder 12 oriented vertically in the drawing is a partial region opposite to the second mold part 7 and is spaced above the machine plate 11 above the machine plate 11 with a guide column. 6 is held in the free end region. In order to be able to move the mold side parts 8, 9 relative to each other in the transverse direction with respect to the path of movement of the second mold part 7, in the illustrated embodiment all mold side parts 8 , 9 are held by the machine plate 11 so as to be slidable along the machine plate 11 using at least one hydraulic cylinder 13 each serving as a side partial drive device.

  As can be seen from FIGS. 2 and 3, at least two mold side portions 8, 9 are provided with projecting closure pins 14, which are at least movable second in the closed position. In this case, the movement path of the second mold part 7 is restricted in the direction opposite to the first mold part 5. . The illustrated embodiment of the die casting machine 1, 10 has closure pins 14 on all its mold side parts 8, 9 that engage the first and second mold parts 5, 7 from the rear. Using the closing pin 14, the mold parts 5, 7 and the mold side parts 8, 9 can be mechanically locked together, in which case the die casting mold 3 is in its closed position in the interior of the die casting mold 3. Can withstand the high operating pressure of the molten metal (also referred to as molten metal).

  For this purpose, the return movement of the mold side parts 8, 9 which can be moved transversely with respect to the path of movement of the second mold part 7 using each one side part driving device is likewise a machine. It can be locked to an expression. For this purpose, each of the side partial drive devices is provided with at least one lock member 16 which is movable between an open position and a lock position. In the locking position, the locking member 16 engages the abutment surface 17 coupled to the mold side portions 8 and 9 to lock the return movement of the side portion driving device. The locking member 16 is also tapered towards its free locking end so that the side of the locking member 16 facing the adjacent mold side portions 8, 9 forms a climbing ramp 18. It has become. Since the abutment surface coupled to the mold side portions 8 and 9 has a slope corresponding to climbing having a complementary shape, the dimensional change caused by heat in this region is also combined with the die casting mold 3. Sometimes it can be compensated well.

  The closing pin 14 protruding from the mold side portions 8 and 9 is held by the mold side portions 8 and 9 movably against the return force in the pin longitudinal direction. In the illustrated embodiment, this return force is generated by a single compression spring, which presses against the back side of a closing pin arranged corresponding to the compression spring. However, it is also possible for the return force acting on the closing pin 14 to be generated by a hydraulic, aerodynamic or electromechanical force generator, respectively. In the closed position of the die casting mold 3, the closing pin 14 engages with a flange 21 that serves as a counterpart receiving from behind. A flange 21 protrudes from each mold part 5 and 7. In this embodiment, the closing pin 14 is tapered toward the end of the pin, and the side face of the closing pin 14 facing the adjacent flange 21 forms a riding slope 22. Yes. The flange 21 is provided with a climbing slope having a complementary shape. Due to the movable configuration of the closing pin 14 and the climbing slope 22 corresponding to the climbing slope, it is possible to satisfactorily compensate for dimensional changes caused by temperature when the die casting molds 3 are assembled together.

  The mold parts 5, 7 and the mold side parts 8, 9 surround at least one cavity 4 in its closed position, into which molten metal necessary for the production of the casting 2 can be poured. In order to allow the molten metal poured into the at least one cavity 4 to be brought under pressure (pressurized), the movable second mold part 7 has two mold members 23, 24. And both mold members 23, 24 can be brought into positions relatively spaced from each other. The upper mold member 24 has a flange 21 that serves as a counterpart, which is engaged from behind by the closure pin 14, whereas the lower mold member 23 is surrounded by the mold side portions 8, 9. It is possible to move into the intermediate room. The mold members 23 and 24 have partial areas which are slidably guided relative to each other, and the partial areas are spaced apart from each other by supplying pressure to the dividing surface located therebetween. Can bring in. By supplying pressure to the molten metal located in the at least one cavity 4 during the cooling and solidification process, the quality of the casting 2 is favorably affected and the mechanical properties of this casting 2 are markedly different. Improvement, the cooling process is accelerated and thus the cycle time is shortened.

  The mold parts 5, 7 and the mold side parts 8, 9 surround at least one cavity 4 in the closed position of the die casting mold 3. Each cavity 4 is provided with at least one air suction opening 25 and at least one supply opening 26 so that the molten metal can be injected into the at least one cavity 4 as a laminar liquid flow. . The air trapped in the cavity 4 can be sucked out via the air suction opening 25, whereas the molten metal can be injected or supplied through at least one supply opening 26. In the movable mold part 7, at least one lock slider 27 is movably guided, which closes at least one supply opening 26 with a sealing action in a closed position and dissolves it. The molten metal in the metal storage portion 28 can be continuously held immediately behind the lock slider 27.

  As can be seen from FIGS. 1 to 5, the molten metal reservoir 28 required for the subsequent casting process is located below the die casting mold 3. This avoids that ambient air can have a detrimental effect on the stored molten metal required for the subsequent casting process, degrading quality. In this case, at least one molten metal pump 29 is incorporated in or provided corresponding to the molten metal reservoir 28, and at least one molten metal in the molten metal reservoir 28 is used by using the molten metal pump 29. It can be transferred into at least one cavity 4 of the die casting mold 3 through the supply opening 26.

  Compared to a general-purpose die-casting machine, the illustrated die-casting machine 1 stands out in a remarkably compact structure. The hydraulic cylinder 12 is necessary only for moving the second mold part 7 and it is not necessary to combine the mold parts 5 and 7 into one. Therefore, the hydraulic cylinder 12 and the second mold part The guide column 6 holding the mold part 7 can be designed correspondingly small. As a result, a relatively small force is required to operate the illustrated die casting machine, so that the die casting machine 1 can save a lot of energy.

  As is clear from the comparison of FIGS. 7 to 9 showing in detail the region of the supply opening 26 of the die casting mold 3 of the die casting machine 10, the lock slider 27 has at least one cavity 4 provided in the die casting mold 3. 7 is moved from the open position shown in FIG. 7 to the closed position shown in FIG. 8, in which the molten metal located in the at least one cavity 4 is required for the subsequent casting process. Separated from the reservoir 28, the supply opening 26 is closed tightly, ie with a sealing action. In the subsequent solidification stage, the mold members 23, 24 are moved to positions spaced from each other by hydraulic pressure, and the molten metal present in the at least one cavity 4 is brought under pressure, so that At this time, the lock slider 27 further sinks into the supply opening 26 provided corresponding to the lock slider 27 (see FIG. 9). However, it is also possible to move the mold members 23, 24 to positions spaced from each other in an aerodynamic, electromechanical or other suitable manner.

  During the melting of the molten metal, the high operating pressure required in the die casting mold 3 is received and transmitted only by the mechanical locking mechanism of the mold parts 5, 7 and the mold side parts 8, 9. . Filling the die-casting mold 3 with molten metal is performed in a mold locked to high pressure resistance. At the same time, pressure is applied to the molten metal 28 using the molten metal pump 29, and a vacuum is generated in the die casting mold 3. In this way, the die casting mold 3 can be filled quickly and in layers without oxides and gases. As is apparent from FIG. 8, immediately after completion of the mold filling, the supply opening 26 is closed using the lock slider 27, so that the molten metal in the die casting mold 3 does not transmit heat and pressure. Disconnected from the molten metal reservoir 28. At the start of solidification of the metal in the cavity 4, pressure is applied using the mold members 23, 24 of the mold part 7 and by the central hydraulic cylinder 12. The pressure is uniformly applied to the casting 2 in the cavity 4 until the casting 2 is completely solidified. Due to the high pressure, an accelerated heat exchange with the die casting mold 3 takes place, which significantly shortens the solidification process. High pressures and short solidification times make it possible to cast metals and alloys, such as, for example, aluminum wrought alloys or forging alloys, which could not be cast in conventional mold casting (Kokillenguss).

  As is apparent from a comparison between the embodiment shown in FIGS. 1 to 3 and the machine configuration 10 shown in FIGS. 4 to 6, the die casting die 3 of the die casting machine 10 manufactures a plurality of castings 2 simultaneously. Therefore, a plurality of cavities 4 can be provided. The die-casting machine 1 shown in FIGS. 1 to 4 has a die-casting mold 3 having only one cavity 4, and in this cavity 4, for example, one light metal wheel can be manufactured. The die casting mold 3 of the die casting machine 10 shown in FIG. 5 is provided with a plurality of cavities 4, and these cavities 4 are used, for example, to manufacture a plurality of pistons simultaneously.
