The lower rail 31 is a double plate rail composed of one plate of the angle and a plate material fixed to the same angle, and the lower rail 32 is a short rail using one plate of the angle. The guide pieces 24 are groove-shaped blocks, two of which are fixed to the lower ends of the outer door 21 and the inner door 22, respectively, and slidably sandwich the lower rail 31. As shown in FIG. 4, the guide piece 24 has its both ends widened outward so that the rail can be easily inserted when the guide piece 24 is disengaged from the lower rail 31 or 32 and then engaged again.

It covers the section between the movable mold platen 5 (position in FIGS. 1 and 2) and the mold clamping cylinder flange 6a when opened, and when performing work in this section, it moves toward the movable mold platen 5 and opens. . 1 and 2
Shows the two safety doors in the closed position, the two-dot chain lines show the open positions of the outer door 21 and the inner door 22, and show the movable die plate 5 in the open position.

扉開口部の下部レールを除去することができる。Since the upper portion of the safety door 20 has a conventionally known structure, its explanation is omitted, and the operation of the lower portion of the safety door 20 will be described. When the outer door 21 is in the closed position, the outer door 2
The guide piece 24 on the lower left side of 1 is engaged with the lower rail 32, and the lower portion of the outer door 21 is restrained from lateral movement at the engaging point. When the outer door 21 moves in the opening direction, the guide piece is disengaged from the lower rail, so that the lower portion of the outer door 21 loses the regulation against the lateral (outward) movement, but the safety door moves outward due to an unexpected external force. When leaning toward, the rotational moment around the upper rail 30 generated by its own weight acts as a restoring force and suppresses it. In addition, the outer door 21 during this movement
If necessary, the worker can assist with the lateral shake (outward shake). When the movement further proceeds, the right guide piece 24 engages with the lower rail 31, and the lateral movement of the outer door 21 is restricted again at the engaging point. Next, the inner door 22
Since the two lower guide pieces 24 are engaged with the lower rail 31 when the is in the closed position, the lower portion of the inner door 22 is restrained from lateral movement at two engaging points. The inner door 2
When 2 moves in the opening direction, the guide piece 24 is sequentially separated from the lower rail 32, and the inner door 22 moves while the lateral movement is restricted by the restoring force based on its own weight as in the case of the outer door 21. However, this state continues while it is opened. As described above, the lower rail of the door opening can be removed without losing the function of the safety door device.

A sectional view is shown. Other configurations are similar to those of the first embodiment. In both figures, 21a is a guide rail provided at the lower part of the outer door 21 and having the same length as the lateral width, and 24a is a guide piece fixed to the lower end of the summing portion of the inner door 22, and the guide rail 21a is slid in the groove. It is movably sandwiched and engaged.
【００２５】次に上記構成の作用を説明する。Next, the operation of the above configuration will be described.

常に解かれることがない。Since the lower guide rail 21a of the outer door 21 and the guide lower piece 24a of the inner door 22 shown in FIGS. 5 and 6 are always engaged, as long as the inner door 22 is in the closed position.
The outer door 21 is indirectly restricted in lateral movement by the lower rail 31 via the inner door 22 no matter what position the outer door 21 is moved to. Further, as long as the outer door 21 is in the closed position, the inner door 22 may be moved to any position through the lower rail 3 through the outer door 21.
The lateral movement (outward rotation) is indirectly regulated by 2. Therefore, the lateral movement of the lower part of the safety door 20 is not always released from the regulation of the lower rail 31 or 32 as in the case described above.

利点がある。As described above, according to the first and second embodiments,
In order to perform mold replacement work, etc., even if the bar 25 is removed and the rear safety door 20, more specifically, the outer door 21 or the inner door 22 is opened,
These doors are configured to move in a state of being suspended by a suspension vehicle 23, and the lower opening has only lower rails 31 and 32 near both ends that do not hinder work. As described above, there is an advantage that the lower rail does not interfere with the work of exchanging molds and other work, and taking out products.
