出しておけばよいことになる。[Detailed description of the invention] This invention relates to a mold reversing machine for the purpose of changing the orientation of a mold. Conventionally, to invert a mold (for example, a mold used for injection molding of synthetic resin), a crane was used to lift it up and the worker manually operated it, but since it is a heavy object, it poses no danger during the work. Not only is this easy to occur, but it is difficult to move slowly, which causes problems such as easily damaging the mold. However, there are some proposals for partially mechanizing the mold reversal process (for example, by fixing the mold to the reversing plate with bolts), but there are problems such as the need for auxiliary tools and the labor required for back and forth work. However, in this invention, the lifting plates are attached to the left and right sides of the horizontal axis so that they can rotate from a horizontal position to an upright position about the horizontal axis, so the lifting plates can be moved while holding the mold in place. By rotating the , all of the problems of the prior art were solved. That is, to explain this invention with reference to an embodiment, the lifting plates 2 and 2a are arranged on the left and right sides of the horizontal axis 1 (in FIG. 1), and each lifting plate 2,
The proximal end of 2a is rotatably attached to the horizontal shaft 1. Brackets 3, 3a are provided protruding from the lower surface of each lifting board 2, 2a, and the tips of rods 4, 4a are rotatably attached to the tips of each bracket 3, 3a.
The proximal ends of the rods 4, 4a are connected to pistons in hydraulic cylinders 5, 5a installed perpendicular to the horizontal axis 1 to form a mold reversing machine. The mold reversing machine of this invention can be embedded, for example, in the passageway below the crane running path, and by keeping the upper surface of the lifting plates 2, 2a flush with the road surface, it can be used as a passageway without any problems when not in use. In addition, since the hydraulic position for operating the hydraulic cylinder can be sufficiently accommodated under the lifting platform, it is only necessary to expose the part necessary for the operation command on the ground.

与えるおそれもないなどの諸効果がある。 Next, pressurized oil is sent to the rod side a or piston side b of the hydraulic cylinders 5, 5a, and the rods 4, 4a are
is moved in and out, thereby rotating the lifting plates 2, 2a via the brackets 3, 3a.The hydraulic system for sending and discharging the pressurized oil will be explained. In FIG. 3, the motor 9 is started, the pump 10 is rotated through the coupling or the shaft 11, and the oil pipe 12 and solenoid valves 13, 13 are rotated.
Pressurized oil is sent to chamber a or b of each hydraulic cylinder 5 or 5a via a or 13b, and is drained from chamber b or a. In the figure, 14, 14a are pistons, 15, 1
5a is a relief valve, 16, 16a is a flow control valve, 17 is a relief valve, 18
is a pressure gauge, 19 is a solenoid valve, 20 is a manifold, 21 is a strainer, 22 is a tank,
23 is an oil level gauge. To use the device of this invention, first place the mold 6 on one of the lifting plates 2 as shown by the chain line in FIG. 2, and then stand the other lifting plate 2a upright. After rotating the mold 6 as shown by the arrow 7 until the mold 6 is stably held by the lifting plates 2 and 2a, the both lifting plates 2 and 2a are rotated 90 degrees in the direction of the arrow 8.
The left side of the mold 6 can be directed upward. Moreover, this mold 6 is lifted again to the loading plate 2 by a crane.
By moving it upward and repeating the same operation as described above (by performing the operation twice), the original lower surface can be turned to the upper surface. When moving a heavy object with a crane, it is possible to move it very slowly, but when reversing it, even if you are careful, you will not only be able to avoid the shock of rolling. Since manual labor had to be used to assist, the work was hard and there was a risk of injury. However, according to this invention, since it is rolled while being clamped on a lifting plate, it can be reversed accurately and reliably, and there is no need for human power and there is no risk of impact on the mold. effective.

The reversing machine can be used effectively in this manner.
