かった。2. Description of the Related Art Generally, a molded product having an undercut portion is forged or melt processed by using a split mold. At this time, when the molded product is separated from the split mold by human power, the split product is taken out together with the molded product left, and the molded product is taken out along the split surface of the split mold.
However, in plastic working, since the punching force against the material is strong, the undercut portion bites significantly into the inner surface of the split mold, and it is often difficult to separate the molded product from the split mold.

ストがかかるとともに欠陥を生じやすい。Further, as a mold device according to the present invention, Japanese Unexamined Patent Publication No. 54-85251 discloses "a split mold for molding a molded product". This will be described briefly. The split mold 51 for molding shown in FIG. 6 includes molds 21 and 22, a central block 42, concave segments 28, 33 and 35, and a crown 45. The concave segment 28 is a guide member 29.
Further, the concave segment 35 is arranged so as to be guided by the guide member 36. Also, the drive plate 4
When 7 is raised, the crown 45 is moved by the shaft 46,
The recessed segment 33 is arranged to be pushed up by the busher 48, and the recessed segment 35 by the fitted central block 42. The releasing operation of the split mold 51 is performed as follows. The mold 22 is moved upward. At this time, the spring 31
The concave segment 28 opens horizontally until the guide member 29 reaches the bottom of the oblique hole 30 due to the urging of the guide member 29 and the guide mechanism of the guide member 29, even if the molded product 23 has an undercut portion. You can leave. The drive plate 47 is raised. At this time, 47-
Between 47A, the shaft 46 pushes up the crown 45, releasing the concave segments 33 and 35. Between 47A and 47B, the bush 48 pushes up the concave segment 33 and rotates it about the axis 34 to raise it. Between 47B and 47C, when the central block 42 lifts the concave segment 33, the concave segment 33 is radially separated along the guide member 36 and the molded product 23 is formed.
And the release is completed. Therefore, in this technique, the molded product 23 is released from the mold 2
At least two operations (lifting of the mold 22 and drive plate 4) are divided into three stages: opening of the concave mold 28 in the inside 2, opening of the concave mold 33, opening of the concave mold 35, and ejection of the molded product 23.
However, there are the following problems. (A) Since the releasing operation involves a plurality of stages, it takes time to release the mold, which may reduce the production efficiency. (B) Since the mold structure is very complicated, the cost of the device is high and defects are likely to occur.

に欠陥を生じやすい。A mold split mold 6 shown in FIG. 7 is used as a mold releasing tool which operates in the same manner as in JP-A-54-85251.
1 is known. The releasing operation of the molding split die 61 is performed as follows. The reinforcing mold 62 shown in FIG. 7 is raised and released from the split mold 63. The movable plate 64 is lifted and the split pins 63 are radially and obliquely opened upward by the inclined pins 65. The molded product 67 is removed from the core 66 and taken out. However, this technique has the following problems. (B) Since only the split mold is opened radially and obliquely upward with the molded product remaining, another device for removing the molded product from the core is required. (B) The structure for making the movable plate mounting portion of the tilt pin slidable becomes complicated, which increases the cost of the device and easily causes defects.

FIG. 1 is a vertical cross-sectional view of a main part of a mold device according to the present invention. FIG. 2 is a plan view of the mold apparatus shown in FIG. The mold apparatus 11 shown in FIG. 1 includes a punch 1, a split mold 2, a reinforcing mold 4, a pressure receiving mold 6, and a movable plate 9.
The punch 1 shown in FIG. 1 transmits the ram pressure of a press (not shown) to the material to accelerate the deformation of the material. The split mold 2 shown in FIGS. 1 and 2 (a) has an inverted frustoconical shape 3
It consists of a block divided into two and has a through hole 2a in the center.
And has a groove 2b on the outer periphery. This through hole 2a and punch 1
The cylindrical part of the molded product is formed in the gap between and. A pattern is formed on the outer surface of the cylindrical part of the molded product by the recess 3 in the through hole 2a, and this pattern part serves as an undercut part for the split mold 2. The inner surface of the reinforcing mold 4 shown in FIG.
It receives the lateral pressure from the mold and holds the split mold 2 by the wedge effect to prevent the blocks of the split mold 2 from shifting during molding. Further, the groove 4a is provided at a position corresponding to the groove 2b of the split mold 2 on the inner surface. A guide pin 5, which is a fitting member, is inserted into the groove 2b and the groove 4a and serves as a fitting means for the split mold 2 and the reinforcing mold 4. The fitting means and the inclination of the angle α in the reinforcing die 4 serve as guide means for radially opening the blocks of the split die 2 obliquely upward when the split die 2 is pushed up by the split die knockout pin 7. . The taper angle α of the outer surface of the split mold 2 determines the ease of separation of the molded product from the split mold 2. In this case, α = 55 ° is set. Further, as a fitting means for fitting the split mold 2 and the reinforcement mold 4, a convex portion 2c formed on the split mold 2 shown in FIG. 2B is used.
The groove 4b may be formed in the reinforcing mold 4 that fits into the groove, or the groove 2d formed in the split mold 2 shown in FIG. 2C and the reinforcing mold 4 that fits into the groove 2d. The convex portion 4c may be formed. The pressure receiving die 6 is a portion that receives the ram roll down force of the punch 1 and forms the bottom of the molded product. Also,
The pressure of the knockout pin 8 is transmitted to push up the molded product. The movable plate 9 is provided with a knockout pin 8 and a split mold knockout pin 7 as a knockout member that simultaneously projects the molded product and the split mold 2. When the movable plate 9 is raised, the knockout pin 8 pushes up the molded product via the pressure receiving mold 6, and at the same time, the split mold knockout pin 7 pushes up the split mold 2 and radially opens each block of the split mold 2.

ことから金型装置１１が単純な構造となっている。Therefore, a knockout member for simultaneously projecting the molded product and the split mold 2 which utilize the inclination of the inner surface of the reinforcing mold 4 which holds the split mold 2 by the wedge effect at the time of molding, is used as the guide means for opening the split mold 2. As described above, since the movable plate 9 is provided with the knockout pin 8 and the split knockout pin 7, the mold device 11 has a simple structure.

１２を貫通孔２ａ内から取り出し動作は終了する。The mold release of the mold apparatus according to the present invention is performed as follows.
The operation is performed. 3 to 5 are cross-sectional views of the mold device at each stage of the mold releasing operation. When the processing is completed, the punch 1 shown in FIG. 3 is released upward. At this time, the molded product 12 is the through hole 2a of the split mold 2.
It is left inside. The support rod 10 with the suction tube shown in FIG. 4 is inserted into the through hole 2a to support the molded product 12 from above.
Then, the movable plate 9 is raised, and the knockout pin 8 pushes up the molded product 12 via the pressure receiving mold 6. at the same time,
Split mold knockout pin 7 pushes up split mold 2. At this time, each block of the split mold 2 moves radially in the direction of the guide pin 5 along the slope of the pressure receiving mold 6. Molded product 12
Is held by the support rod 10 and rises, so that the molded product 12 is separated from the split mold 2. If the angle α of the inclination of the inner surface of the split mold 2 is reduced, the mold can be released with a short push-up stroke, and if the angle α is increased, the push-up stroke required for the mold release becomes long. This taper angle α may be appropriately selected according to the amount of undercut. The movable plate 9 is further raised to move the split mold 2 further obliquely upward so as to be completely separated from the molded product 12. Further, the knockout pin 8 pushes up the pressure receiving die 6 and pushes it up further. After pushing up to the required height, the molded product 12 is sucked by the support rod 10 with the suction tube shown in FIG. 5, and the operation of taking out the molded product 12 from the through hole 2a ends.
