Abstract

The invention relates to foundry, in particular, to injection molds. The purpose of the invention is to reduce the production capacity of castings due to the separation of the mold residue from the casting in the process of opening the mold. The mold contains a divider 2 with a shank 3 mounted in the movable mold 1 and spring-loaded latches 4 holding the divider 2 in the initial position. When pressing the metal from the pressing chamber 6 by the pressing piston 7, the divider 2 moves back, opens the sprue channel 18 and rests with its bevel 13 into the bevel 12 of the slide 10, which with its other bevel 11 acts on the bevel 9 of the stop 8. The latter rests against the stationary half-form 5 When opening the mold, the pressing piston 7 advances the divider 2 to the left with a press residue, which is separated from the gate channel 18. At the same time, the divider 2 shifts the slider 10 down. Paul; v / i (L with iMk SP tm-. y

The invention relates to foundry, in particular to injection molding.

The aim of the invention is to reduce the labor intensity of manufacturing castings by separating the press residue from the casting in the process of opening the mold.

FIG. 1 shows the mold in the initial position, a general view; in fig. 2 - the same at the time of completion of filling; in fig. 3 - the same, at the time of trimming the press residue

The mold contains a movable mold 1 with a movably mounted divider 2 with a shank 3 and spring-loaded latches 4, a stationary half-mold 5 with a pressing chamber 6 and a pressing piston 7.. In the movable half-form, an emphasis B is installed, on one end of which there is a bevel 9 and a slider 10 with bevels 11 and 12 on both ends. On the divider 2 is made of bevel 13, interacting with the bevel 12 of the slide 10. The stop 8 is installed with the possibility of the interaction of the bevel 9 with the bevel 11 of the slide 10, and the end with the fixed half-form 5.

The mold also contains an inlay plate 14, a plate 15 with pushers 16. In the press chamber 6, a vent channel 17 is made, connecting the press chamber to the sprue channel 18.

The mold works as follows.

After the pressing chamber 6 is filled with liquid melt, the pressing piston 7 acts through the melt on the divider 2, having previously expelled the air from the pressing chamber through the ventilation duct 17, sprue channel 18 and, sealing the melt, squeezes it to the position (Fig. 2) when the bevel 13 rassekatel 2 rests on the bevel 12 of the slide 10. In this

The mentor divider 2 opens the sprue channel 18, the melt is pressed into the mold and crystallized. In the following (Fig. 3), at the time of opening of the mold, a gap is formed between the movable half-form 1 and the fixed half-form 5. Pressing the piston 7 exerts pressure on the divider 2 through the press residue. The divider 2 under the action of this pressure begins to move away and press with a bevel 13 on the bevel 12 of the slide 10, which with the second bevel 11 presses against the bevel 9 of the stop 8 and presses the stop 8 into the gap between the half-molds 1 and 5. When the dissector 2 departs, the shank 3 depresses the spring-loaded locks 4 and extends beyond the base plate. The press residue under the action of the pressing piston 7 advances after the divider 2. In this case the gate channel 18 is cut and the press residue is separated from the casting.

After the mold has been opened using the plate 15 and the pushers 16, the casting is pushed out of the movable mold half 1. The plate 15 presses the shank 3 and the divider 2 returns to its original position and is fixed with spring-loaded locks 4 The pressed piston 7 also returns to its original position.

form b, bevel 9 returns the slider 10 to its original position. The mold is ready for melt pouring.

The separation of the press residue in the process of opening the mold reduces the labor intensity of casting, leading to an increase in productivity.
