Further, if necessary, a packing band 42 is hung on the upper surface of the main body cover 1 through the band insertion hole 16 provided in the bogie 3 shown in FIG. 7 to fix the main body cover 1 and the bogie 3.

When the truck is loaded on the truck bed in this state, the fork of the forklift is inserted from here because the fork groove 27 is formed in the vertical and horizontal directions of the bottom of the truck 3 as shown in FIG. Can be lifted and loaded onto the carrier. When moving the truck by hand, the lever 3 attached to both sides of the truck 3
When the cylinder 7 is rotated upward, a cylindrical bush receiver 36 attached to the end of the cylinder bush rotates a bearing hole 39 formed on the side surface of the bogie 3 as shown in FIG. The fitted bush 33 rotates. Along with this, the support plate 34 formed integrally with the bush 33 also rotates,
As shown in FIG. 12, the rear caster 29 is rotated downward about the support shaft 31 so as to be integrated with the upper surface plate 30 of the rear caster 29 fitted to this side surface, and Protruding from the bottom.

Next, the lever 37 on the opposite side of the bogie 3 is turned upward so that the casters 29 are similarly projected. In addition, the casters 28, 28 on the front side also rotate the lever 35 upward, so that the casters 28, 28 rotate downward and protrude from the bottom of the cart 3. In this case, the casters 28 and 29 rotate to the position passing through the lowest point and touch the ground, so that the weight of the transport storage box and the weight of the transported product are added. Therefore, the casters 2 and 29 need not be separately provided with a lock mechanism.
8, 29 are locked automatically and never return. Therefore, the locked state of the casters 28 and 29 is not released during transportation through a somewhat uneven passage by this mechanism.

With the casters 28 and 29 thus protruded, the carriage 3 is moved by pushing the body cover 1 by hand. In this case, the front caster 28 is a free caster that rotates back and forth and right and left, and the rear caster 2
9 is composed of a one-way caster that rotates only in the front-rear direction, so that the direction can be easily changed. When retracting the casters 28 and 29, the lever 35
After lowering the lever 37, the caster 2
8 and 29 are stored inside the carriage 3.

When the mold 15 is moved from the storage location to the maintenance location or the side of the molding machine in the molding factory,
Since it can be pushed and moved while the casters 28 and 29 are put out on the carriage 3, it is not necessary to use a pallet on which the mold 15 is placed, a forklift, a lifter, a carriage, a crane, or the like for transporting. In this case, the wide fork groove 27 is formed in the center of the bottom surface of the bogie 3, so that the belly can be prevented from climbing up when passing over a step in the passage or near the slope end.

When a plurality of dies 15 are to be stored, as shown in FIG. 15, when a combination of the cover 1 containing the dies 15 and the main body base 2 is stacked in a plurality of stages, The convex portion 10 formed on the bottom surface of the main body base 2 fits into the concave portion 8 formed on the upper surface of the cover 1, so that it can be stably stacked.

When the mold 15 is stored in the transport storage box for long-term storage, a vaporizable rust inhibitor is put inside the waterproof sheet 14. Since the vaporizable rust preventive has a specific gravity heavier than air, the waterproof sheet 14 stopped by the sheet stopper 20 is used.
Even if the upper part of the opening is open, the gaseous vaporized rust inhibitor is hard to leak. For this reason, even if the band insertion hole 16 is opened in the main body base 2, the rust prevention effect can be maintained for a long period of time. Further, the central portion of the soft waterproof sheet 14 is sandwiched between the soft plates 11b and 11c, so that the mold 15 can be protected from being broken by direct contact.

Even if a fire occurs and water is extinguished by fire extinguishing, since the mold 15 is housed in the main body cover 1 having an open lower part, the mold 15 does not get wet. Further, even when the factory is submerged due to flooding, the lower part of the main body cover 1 is opened and connected to the main body base 2 by a buckle 5, and the lower side of the main body cover 1 is connected to the main body base 2 as shown in FIG. Since it is fitted in the groove, it does not swell due to water pressure and does not come off the body cover 1 due to buoyancy.

Also, the band insertion hole 1 of the main body base 2 should be used.
Even if water infiltrates into the main body cover 1 from 6, the internal air is compressed, but the internal pressure increases and the water level rises only to a predetermined height. In particular, when the mold 15 is wrapped with the soft waterproof sheet 14, the waterproof sheet 14 comes into close contact with the surface of the mold 15 when water enters, so that the volume of the lower space of the main body cover 1 is increased, and the sheet stopper 20 is formed. The mold 15 can be protected from submersion without the water level rising to the upper part where there is a gap.

FIGS. 16 and 17 show another embodiment of the present invention comprising a main body cover 1 and a truck 3. The main body cover 1 is formed similarly to FIGS. The cart 3 has a rectangular projection 48 formed on the upper surface thereof so as to fit into the bottom opening of the main body cover 1, and a plurality of band insertion holes 16 penetrate up and down on the outside thereof as shown in FIG. 17. It is open. This band insertion hole 16
The mold 15 placed on the protruding portion 48 is fixed through a packing band.

A U-shaped groove 18 is formed on the upper periphery of the projection 48, and an engagement hole 49 is formed on the lower side of the side of the projection 48.
Is opened. A protrusion on the lower peripheral edge of the main body cover 1 is fitted into the U-groove 18, and an engaging piece 5 a protruding in the lateral direction of the buckle 5 is inserted into the engaging hole 49 and engages with the main body cover 1. The carriage 3 is integrally connected. The other components such as the mechanism for the casters 28 and 29 provided on the cart 3 such as the retracting mechanism are the same as those described above, and will not be described.

In the transport storage box having the above configuration, when transporting the mold from the mold manufacturing factory to the molding factory, the mold 15 is placed on the protrusion 48 on the upper surface of the carriage 3. Next, the mold 15 is tightened by passing a packing band through the band insertion hole 16 opened in the cart 3 and fixed to the cart 3, and then the main body cover 1 is covered. Thereafter, as shown in FIG. 17, the buckle 5 is attached to the periphery of the lower portion of the main body cover 1, and the engaging piece 5 a projecting in the lateral direction of the buckle 5 is inserted into the engaging hole 49 opened on the side surface of the projecting portion 48 of the truck 3. After inserting and engaging the main body cover 1 and the carriage 3 integrally, the levers 35 and 37 are rotated upward, and the casters 28 and 29 are protruded as shown in FIG. 3 is moved. In this case, a structure in which a waterproof sheet 14 is attached to the upper surface of the cart 3 may be used.

FIG. 18 shows another embodiment of the present invention, in which the elevating and lowering of the casters 29 is supported by an eccentric shaft, and the casters 29 are mounted on the bottom surface of the carriage 3 so as to be freely protruded and retracted. In this method, the shaft 45 supporting the casters 29 is mounted eccentrically from the center of the boss 46, and the boss 46 is rotatably inserted into a bearing hole opened on the side surface of the bogie 3, and the lever 47 is attached to the side surface of the boss 46. It is attached.

By rotating the lever 47 upward, a large force acts on the shaft 45 mounted eccentrically by shifting the center of the boss 46 by the lever principle to rotate the shaft 45. Mounted caster 29
Descends. In this case, the caster 29
Can be automatically locked by turning to a point before the lowest point to ground.

In the above description, the structure in which the casters 29 are moved up and down using the eccentric shaft has been described. However, a structure in which the rotating shaft is moved up and down may be used. In the above description, the case where a long lever is provided is shown.
A structure in which a pipe is detachably attached and this pipe is used as a lever may be used. In addition, the band insertion hole 1
Although the structure in which the hole 6 is opened is shown, a structure in which a projection provided with the band insertion hole 16 is formed on the upper surface of the main body base 2 and the inside is sealed with the main body cover 1 covered may be used. Although the structure in which the upper part of the waterproof sheet 14 is squeezed by the sheet stopper 20 has been described, the inside of the waterproof sheet 14 may be sealed with a rope. Further, the storage case 40 may have a structure integrally formed inside the main body cover 1.

The mold 1 on the upper surface of the main body base 2 and the trolley 3
If the portion on which the main body 5 is placed is protruded upward and is higher than the lower peripheral edge of the main body cover 1 in a state where the main body cover 1 is combined, even if water enters the main body cover 1, the internal pressure increases, so It is possible to prevent the mold 15 from getting wet without immersion. In the above description, the case where the mold 15 is transported and stored is described.
