Abstract

PURPOSE: To automatically match the axes of an upper die and a lower die and obtain a trimming device which does not develop trimming mistake and interference by freely shifting the upper die in the horizontal direction and rotatably supporting this die to a die base to the vertical axis. CONSTITUTION: After setting a work 3 with a runner 4, etc., in the lower die 2, when the upper die base 7 descends, the work 3 is elastically held with a holding part 8 and the lower die 3. Further, when the upper die base 7 descends, a tracing part at the tip part of the upper die is guided to the side surface of the work 3 and the upper die 9 is shifted in the horizontal direction to the position surely engaging the upper and the lower dies. Even in the case of deviating the upper die 9 to the lower die 2 around the vertical axis, since the upper die is rotatable to this vertical axis, the upper die 9 and the lower die 2 are surely engaged. In such a way, the trimming device without developing defective cutting-off of the runner 4 and the interference of the die is obtd.

2. Description of the Related Art FIG. 5 is a front view showing a conventional trimming device T1. In this trimming device T1, a lower mold 2 is provided on a lower mold base 1. The lower die 2 constitutes a work set table, on which the work 3 is placed. A runner 4 and an overflow 5 are integrally attached to the work 3 before trimming. Since the runner 4 is heavy, it is supported by the weir receiver 6 provided on the lower mold base. An upper mold base 7 (an example of a mold base member) that can be raised and lowered with respect to the lower mold base 1 includes a gripping member 8 elastically supported, an upper mold 9 having a blade portion, and a hanger clamp mechanism 10. Is provided. The hanger clamp mechanism 10 is composed of an air cylinder 10a and a clamp arm 10b which is rockably driven by the air cylinder 10a. Such a conventional device is disclosed in, for example, Japanese Utility Model Publication No. 4-42053. In the trimming device T1 as described above, after the work 3 having the runner 4 and the overflow 5 is set on the lower mold 2 as shown in the figure, the upper mold base 7 is lowered,
The work 3 is elastically gripped between the gripping member 8 and the lower mold 2. When the upper die base 7 is further lowered, the lower die 2 and the blade portion of the upper die 9 are engaged with each other, and the runner 4 and the overflow 5 are cut off. After that, the clamp arm 10b is swung by the air cylinder 10a to grip the trimmed work 3 and the upper die 9 rises to separate the work 3 from the lower die.

In the above-mentioned conventional trimming apparatus, the lower mold 2 is fixed to the lower mold base 1 and the upper mold 9 is fixed to the upper mold base 7, and the upper mold base 7 is fixed to the lower mold base. Since it only moves up and down relative to 1, especially in the case of a multi-piece work, the lower die 2 may not be set properly, or even if it is set, the center of the upper die 9 is not exactly aligned. Then, inconveniences such as leaving a part of the runner 4 and the overflow 5 or cutting out the work more than necessary occur. The present invention aims to solve the problems in the prior art as described above, and adds a mechanism for automatically aligning the upper die with respect to the work.

According to the present invention, when the upper die is lowered, the tip of the upper die interferes with the side surface of the work, but since the upper die is movable in the horizontal direction with respect to the lower die, the tip of the upper die is Since the upper die moves horizontally to the position where the upper die and the workpiece are accurately engaged by being guided to the side surface of the work, inconveniences such as leaving a part of the runner uncut or cutting the work more than necessary are eliminated. It Further, even when the upper die is displaced in the direction of rotation about its vertical axis with respect to the lower die, the upper die can freely rotate about its vertical axis with respect to the lower die in the present invention. , Smooth meshing between the upper mold and the workpiece is achieved,
In this respect as well, problems such as poor cutting of the runner do not occur.

Therefore, in the apparatus of this embodiment, as shown in FIG. 1, after the work 3 with the runner 4 and the overflow 5 is set on the lower die 2, the upper die base 7 is lowered, and the gripping member 8 The work 3 is elastically gripped between the lower mold 2 and the lower mold 2. When the upper die base 7 further descends, the side surface of the work interferes with the copying portion 9f at the tip of the upper die 9, but the upper die 9
Is movable in the horizontal direction with respect to the lower mold 2, so that the copying portion 9f at the tip of the upper mold is guided by the side surface shape of the work, and the upper mold 9 moves in the horizontal direction to a position where the upper and lower molds are accurately meshed with each other. At this time, since the flange portion 9b of the upper die 9 is supported by the holder 9c by the rotatable balls 11 and 12, the movement in the horizontal direction is smooth. Also, the upper mold 9
Even if the upper mold 9 is deviated from the lower mold 2 in the direction of rotation around its vertical axis, in this embodiment, the upper mold 9 is replaced by the lower mold 2.
On the other hand, since it can freely rotate freely around its vertical axis, problems such as poor runner cutting and interference between the upper die and the work do not occur. Also, when actually trimming,
A large upward force is applied to the upper mold 9, but at that time, the spring 7b is pushed through the ball 11 and the spring 7b bends so that the ball 11 is retracted into the ball accommodating hole 7a. It comes into direct contact with the upper mold base 7. After that, the clamp arm 10b is swung by the air cylinder 10a, and the upper die base 7 is lifted while holding the trimmed work 3 to separate the work 3 from the lower die.

At this time, in the conventional example (FIG. 5), the runner 4
Is supported by a fixed weir receiver 6, so that the clamp arm 1
0b interferes with the runner 4 and causes the runner to fall, or a work grip error occurs. However, in this embodiment, as shown in FIGS. The mold 2 is swingably mounted about a fulcrum pin 13 and is constantly elastically urged upward by a spring 14. Further, the upper die 9 is provided with a pressing rod 15 that abuts the weir receiver 6 and swings the weir receiver 6 downward when the upper die 9 descends. Therefore, as described above, when the upper die base 7 is lowered to grasp the work 3 by the grasping member 8 and the lower die 2, and the work 3 is grasped between the lower die 2 and the grasping member 8, Since the presser bar 15 contacts the weir receiver 6 and swings the weir receiver 6 from the state shown by the two-dot chain line in FIG. 4 to the solid line, the runner 4 on the weir receiver 6 is Dropped from above, then air cylinder 10
When the clamp arm 10b grips the work 3 by a,
The inconvenience that the clamp arm 10b interferes with the runner 4 is avoided.

Since the trimming device according to the present invention is configured as described above, the upper die moves horizontally until the upper die and the lower die automatically coincide with each other when the upper die descends. At the same time, since it freely rotates around the vertical axis, there is no inconvenience such as trimming error or vertical die interference.
