Further, a polster 6 for fixing the lower mold is horizontally arranged in and out from the bed 3 by means of a moving device (not shown) such as a motor or a cylinder. At the center of both sides of the reversing slide 4, there is a reversing shaft 7 as shown in FIGS.
The reversing shaft 7 is provided with a tooth profile 8a on the lower part of its circumference, and its both sides are provided with planar sliding surfaces 8b,
A toothless pinion 8 with a diameter of 8c is attached, and a reversing slide 4 separated from the slide 2 can be moved up and down along a rack column 9 vertically provided between the slide 2 and the bed 3. As shown in the figure, the rack column 9 has its upper end fixed to the slide 2 and its lower end freely inserted into the bed 3 via an insertion guide 10, and has a missing tooth in the middle part separated from the lower surface of the slide 2 by a predetermined distance. Engages with pinion 8 to move toothless pinion 8 to 180
The upper and lower portions of the rack teeth are provided with flat vertical guide surfaces 9a and 9b, and the sliding surfaces 8b and 8c on both sides of the partially toothed pinion 8 are in sliding contact with each other. The reversing slide 4 is raised and lowered in a horizontal state except when reversing. Also, Figures 1 and 2
As shown in the figure, the reversing slide 4 has rigid brackets 11 protruding from both sides to which the reversing shaft 7 is inserted and connected.
Return cylinder 2 with a rod protruding from the side that can be raised and lowered freely
This allows it to be pushed upward via this bracket 11. 13 is a lifting guide for the slide 4 arranged on the side of the column of the press body 1, and 14 is a lifting guide for smoothly lifting and lowering the reversing slide 4 arranged toward the bracket 11 side of the column. be.

When the toothless pinion 8 reaches the position of the rack teeth of the rack column 9, the rack teeth start to engage with the tooth profile 8a of the toothless pinion 8, as shown in the center view of FIG. 3, and the reversing slide 4 descends automatically. rotate. Then, as shown in the right view of Fig. 3, the engagement ends at a position rotated by 180 degrees, and the other sliding surface 8c of the partially toothed pinion 8 comes into contact with the lower guide surface 9b, keeping the reversing slide 4 horizontal again. The bolster 6 is lowered by its own weight to the upper surface of the bed 3 which has been moved outward. As a result, the lower mold on the upper surface of the bolster 6 and the upper mold on the reversing slide 4 are placed on the same plane, allowing the operator to efficiently perform inspections, processing, corrections, etc. in a comfortable downward posture. It is. When the work is finished, the bracket 11 is pushed up by the return cylinder 2, the reversing slide 4 is reversed by the reverse stroke and pushed up until it comes into close contact with the lower surface of the slide 2, and the detachable pin 5a is inserted into the hole of the reversing slide attachment/detachment bracket 5. It is inserted, fixed and pressed. Also,
In trial work, etc., the reversing slide 4 is fixed in close contact with the lower surface of the slide 2, and is raised and lowered together with the slide 2 by the slide raising/lowering pressurizing device using the raising/lowering guide 13 as a guide, so that great rigidity can be obtained.

As described above, in the present invention, if the inverted slide separated from the slide is lowered along the vertical rack column,
The flat sliding surface on the side of the missing-tooth pinion attached to the side of the reversing slide allows the reversing slide to be lowered horizontally along the rack column, and on the way down, it touches the rack teeth in the middle of the rack column. The tooth profile of the toothless pinion engages and the reversing slide can be automatically reversed 180 degrees, allowing the upper mold to be placed on the same plane as the lower mold on the bed, allowing the operator to comfortably face downward. This allows for efficient mold modification work.

In addition, as the reversing slide can be automatically reversed by the rack and pinion as described above, there is no need for other reversing drive devices such as motors, and even in trial presses etc., the reversing slide can be tightly fixed to the slide. It can be pressed and has the excellent effect of providing great rigidity.

1. The reversing slide, which attaches the upper mold to the lower surface of the slide of the press machine that can be raised and lowered, can be raised and lowered independently of the slide along a rack post that has rack teeth in the middle part that hangs between the slide and the bed. At the same time, a bolster for attaching the lower mold is arranged so as to be movable horizontally in and out of the bed, and approximately one-fourth of the circumference of the lower part has a tooth shape that engages with the above-mentioned rack tooth profile. A toothless pinion whose both sides are planar sliding surfaces that can be slid along the above-mentioned rack pillar is attached to the side surface of the reversing slide, and the reversing slide separated from the slide is reversely slid onto the rack pillar. The sliding surface of the pinion with missing teeth on the side of the rack slides down, and the rack tooth profile on the middle part of the rack pillar engages with the pinion with missing teeth on the reversing slide, so that the reversing slide can be freely reversed 180 degrees, and it is reversed. A mold reversing device for a press machine, characterized in that a reversing slide is formed so that it can be freely lowered and installed on a bed where a bolster has been moved.
