First, the mold reversing precipitator of the present invention grips and fixes the mold separated from the press and the injection molding machine, and again, a pair of molds after the maintenance work is completed by facing the upper part (upper side) so that the exposed part of the mold is convenient for work. In accordance with the original to be installed in the press, injection molding machine will be described based on this order as described above.

That is, the mold separated from the press and the injection molding machine is transferred to the mold inverter of the present invention by a forklift or the like and placed on the upper portion of the lower mold work table 17. At this time, the upper and lower molds (A) and (B) conveyed by the forklift are in a state in which they are relatively inconsistent with the lines forming the support grooves 17 'in the lower mold work table 17 as shown in FIG. Since it is mounted, it must be matched before being gripped and fixed to the lower mold working table 17 and the upper mold table 10.

At this time, a position where the adjustment interval 21 inserted into the adjustment hole 20 formed on the pedestal 16 according to the size of the upper and lower molds A and B coincides with the molds A and B to some extent. After moving along the adjusting hole 20, the hydraulic cylinder 23 is operated to raise and lower the upper and lower operating sections 22, and the length 25, which is screwed in the adjusting hole 22 ′, is turned to the handle 24. The tip of the tip 25 is in contact with the side of the mold (A) (B), but supports the end of the tip 25 formed in the opposite position and the right position of the operator (which is prescribed for convenience according to the position of the operator) Align the line 17 'with the line forming the groove 17', and then turn the handle 24 formed at the operator's position and the left position to allow the pusher 25 to support the molds A and B from above. When it is gradually pushed to coincide with the line forming the groove 17 ', the molds A and B are pushed out accordingly to coincide with the ends of the fixed push rod 25. It will not move anymore.

By this operation, the mold (A) and (B) coincide with the line forming the support groove 17 ', and then the clamp support 29 inserted into the support groove 17' freely and inserted into the mold A is As shown in FIG. 5, the upper portion of the clamp 41 is inserted into the recess formed in the side of the lower mold B, and the clamp 41 and the clamp paper are moved to the position of (B). When the earth 29 is matched and fastened by the fastener 37, the lower mold B is fixed on the lower mold table 17 by the clamp 41. Of course, the number of clamps 41 for fixing the lower mold (B) can be changed according to the size, weight, etc. of the mold.

Since the lower mold (B) is fixed to the lower mold table (17), the upper mold (A) should be fixed to the upper mold table (10), so that at least a certain amount of space is provided in the upper mold (A) and the upper mold table. It is formed between (10) and will have to raise the upper mold (A).

At this time, when the hydraulic cylinder 19 is operated, the base 16 fixed to the cylinder rod 19 'is raised, and the guide rod 47 fixed to the bottom edge thereof is also guide hole 18' of the guide support 18. When the base 16 rises without tilting in any direction according to the weight of the molds (A) and (B), the upper surface of the upper mold (A) is brought into contact with the bottom surface of the upper mold work table (10). After stopping the pedestal 16, the upper mold (A) is fixed to the upper mold work table 10, which is the support groove (10 ') formed on the upper mold work table 10 as described above Since it is installed in line with the support groove 17 'of the lower mold work table 17, the clamp support 29 is inserted into the support groove 10' as it is without adjusting the movement of the upper mold A.

(See Figure 5).

In order to protect the upper and lower molds (A) and (B) while the upper mold (A) is fixed on the upper mold work table (10), the hydraulic cylinder (19) is first opened by the lower mold work table (17). After operating and lowering, the exposed part of the upper mold (A) faces downward, so it is necessary to invert it upward.

At this time, when the hydraulic cylinders 14 and 14 ', which are fixed to the operating shafts 13 and 13' fixed on the lower inner projections 12 and 12 'of the swing arms 6 and 6', Since the cylinder rods 15 and 15 'push the operating shafts 13 and 13' by the operation of the hydraulic cylinders 14 and 14 ', the swing arms 6 and 6' are rotated. The upper mold which rotates in the bearings 8 and 8 'installed on the braces 7 and 7' fixed on the pedestal 3, with the main shaft 36 as the main shaft, thereby fixing the upper mold A. The reinforcement plate 11 is inverted together with the work table 10 so that the upper surface of the reinforcement plate 11 is supported on the upper portion of the support 5, and the upside over 4 mounted on the upper end thereof is the swing arm. (6) (6 ') is inverted to mitigate the impact of the lowering as well as to prevent the upper mold (A) from deviating from the fixed position of the upper mold work table 10 (see also FIG. 6).

Thus, what is necessary is just to perform a series of operations, such as repair of the upper mold A, in the state which made the injection part of the upper mold A facing the upper part (upper).

In addition, the lower mold work table 17 is lowered by the operation of the hydraulic cylinder 19 to the operator's elongation or a convenient position, so that the lower mold (B) may perform a series of operations such as repair. .

When a series of work processes such as repair of the upper and lower molds (A) and (B) are completed, the exposed parts of the upper and lower molds (A) and (B) should be combined to be fitted to the press injection molding machine. In this case, since the upper mold A and the swing arms 6 and 6 ', which are inverted, are first returned to their original positions, the projections 12 and 12 of the swing arms 6 and 6' are also performed. When the working shafts 13 and 13 'fixed to') are pushed by the operation of the hydraulic cylinders 14 and 14 ', the swing arms 6 and 6' are driven to their peaks. To return to its original position while rotating in bearings 8 and 8 'so that a reinforcement plate 11 fixed to the upper bottom of the swing arms 6 and 6' is supported on the support 5 '. The upside over 4, which is installed at the upper end thereof, is reversed as described above to alleviate the impact of the swinging arms 6, 6 'and the like which descend.

In this state, the lower mold working table 17 lowered by the operation of the hydraulic cylinder 19 is raised so that the upper surface of the lower mold B is brought into contact with the bottom surface of the upper mold A. Stop, and then release the fastener 37 from the clamp support 29 that is fastened to the support grooves 10 'and 17' of the upper and lower mold work tables 10 and 17 again.
