The mold reversing device 1 has a base portion 2 and a reversing portion 3 rotatably and floatably supported by the base portion 2 . A mounting portion 5 is provided on the reversing portion 3, and the upper mold 4 is detachably mounted on the mounting portion 5. As shown in FIG.

The reversing section 3 has a pair of left and right rotors 16 having an arc-shaped outer peripheral surface. The mounting portion 5 is provided between the pair of left and right rotating bodies 16 . The attachment portion 5 is composed of a magnet plate 17 having a rectangular shape in a plan view and capable of attracting the back surface of the mold 4 by magnetic force.

As shown in FIG. 8, the magnet plate 17 has a rectangular attraction surface in plan view, and a plurality of magnet units 25 are embedded in the attraction surface. A reinforcing rib 26 is provided on the back surface of the magnet plate 17 (see FIGS. 6 and 7) to prevent the magnet plate 17 from bending.

The magnet units 25 are arranged in a direction that obliquely intersects each side of the rectangular magnet plate 17 . The reason for this arrangement is that the suction surface on the back surface of the mold 4 is not a flat surface but a recessed portion and has a rib structure R, so the grid arrangement reduces the suction surface area. It is from.

This proximity switch is also located below the lowest end of the rotor 16 (on a vertical line passing through the center of the rotor).

As shown in FIG. 13, the base portion 2 has a pressing portion 30 that presses against the floating rotating body 16 to prevent the rotating body 16 from rotating. The pressing portion 30 has a fluid pressure cylinder 31 provided on the base portion 2 , and is configured such that the tip of the cylinder rod 32 of the cylinder 31 presses the outer peripheral surface of the rotating body 16 .

The cylinders 31 are provided at equal positions of 30 degrees on both front and rear sides of a vertical line passing through the center of rotation of the rotating body 16 . Therefore, by supporting the lower outer peripheral surface of the floating rotating body 16 with the two cylinder rods 32, the rotating body 16 is prevented from rotating and locked.

14 is a circuit diagram of the fluid pressure cylinder 31. As shown in FIG. The air-driven pump P1 is a hydraulic pump driven by air pressure PA supplied via a filter regulator FR. A hydraulic discharge circuit of the air driven pump P1 is connected to the hydraulic valve V1. The hydraulic valve V1 is controlled by an air solenoid valve SOL1. An air solenoid valve SOL1 is connected to the air pressure PA. A circuit connected to the cylinder of the pressing portion is connected to the hydraulic valve V1. A pressure switch PS1 is connected to the circuit of the cylinder and the hydraulic valve V1. Symbol AB is an air vent valve, and PG is a pressure gauge.

What is shown in FIG. 15 is the operation of cylinder 31 . The initial state is shown in FIG. In this initial state, the tip of the cylinder rod 32 and the outer peripheral surface of the rotor 16 are not in contact. Therefore, the rotor 16 is rotatable. In the circuit diagram of FIG. 13, this initial state is when the hydraulic pressure supply circuit of the cylinder 31 is connected to the drain circuit of the hydraulic valve V1, and the cylinder 31 is not supplied with hydraulic pressure.

In FIG. 4B, the tip of the cylinder rod 32 is pressed against the outer peripheral surface of the rotating body 16 at low pressure in the operating state. This state is performed before the mounting device 7 is inserted under the mounting portion 5 and attempts to raise the mounting portion 10 . In the circuit diagram of FIG. 13, pressure oil from an air-driven pump P1 is supplied to the cylinder 31 through a hydraulic valve V1. A rise in the pressure in the circuit is detected by the pressure switch PS1, and it is confirmed that the cylinder rod 32 is in close contact with the rotor 16. Upon receipt of this confirmation, the placing section 10 starts to rise.

In FIG. 4(c), after the centering process is finished, the reversing part 3 is lifted as the mounting part 10 rises in the joining process, and the rotating body 16 is also lifted. is in a state of At this time, the proximity switch of the floating detection means 29 detects the floating, and the lifting of the placing section 10 is stopped. This completes the bonding process.

FIG. 4(d) shows the state in which the upper mold 4 and the magnet plate 17 are released from the adsorption and the mounting portion 10 descends. Descending of the rotating body 16 is prevented by the cylinder rod 32, and the rotating body 16 is fixed in the floating state. At this time, the pressure oil in the cylinder is prevented from flowing out by the check valve CV provided in the hydraulic valve V1, and the fixed state of the rotor 16 is locked.

The mounting portion 10 descends, and the upper surface of the pair of upper and lower molds 4 and the lower surface of the mounting portion 5 are completely separated. By switching the hydraulic valve V1, the hydraulic pressure in the cylinder is connected to the drain circuit and drained. At this time, the drain circuit is provided with a speed controller (not shown), which suppresses the rapid lowering of the cylinder rod 32 and returns to the initial state shown in FIG.

By using such a levitation-type mold reversing device 1, the mounting portion 5 floats in the centering process and the joining process. also enables smooth coupling.

However, the present invention is not limited to a floating mold reversing device, and can be applied to a non-floating mold reversing device.

The movable plate 13 is formed with an air passage 48 that communicates with the air reservoir (recess 46), and the air passage 48 is connected to a pressurized air source. Note that the air seal is not limited to the labyrinth seal.

By supplying pressurized air from a pressurized air source to the air reservoir 46, the movable plate 13 floats above the substrate 12 and becomes freely movable in the XY plane.

In the alignment step, the handle 45 is operated to align the guide post 15 and the guide bush 14 of the upper and lower molds so that their axes are aligned. This handle 45 constitutes the manual operation section of the present invention.

In this example, six movable plates 13 are provided, each movable plate 13 is provided with an air reservoir 46, and each air reservoir 46 is supplied with pressurized air. The periphery of the air reservoir 46 is sealed with a labyrinth seal. The upper surface of each movable plate 13 is used as a mold mounting surface. Air ejection holes 51 of the contact placement detection means 49 are formed on the upper surface of the movable plate 13 at the four corners.

Although a plurality of movable plates 13 are provided in this example, a plurality of air reservoirs 46 may be formed in one movable plate 13 .

By providing a plurality of air reservoirs 46 in this manner, the pressure of each air reservoir 46 can be individually adjusted. Since the center of gravity of the mold is eccentric, it may not be possible to float uniformly with a uniform air pressure. In such a case, uniform levitation becomes possible by individually adjusting the pressure of the supplied air.
