Example 1 of a press for o-ring molding

2 and 3 illustrate a first embodiment of a press for forming an O-ring according to the present invention. In the first embodiment, the upper mold 22 (1) for pressing the mold (2) while heating the mold (2), and a pressurizing section (11) for pressing the mold (2) A movement limiter 33 protruding from the upper portion of the mold transferring unit 3 to limit the movement distance of the mold 2 according to the size of the mold 2, (40) for fixing the other side of the upper mold (22) to the entire surface of the pressing portion (11) of the press in order to prevent an accident caused by the rotation of the upper mold (22) .

A handle 23 is formed on the front surface of the upper mold 22. The upper mold 22 is mounted on the mounting unit 40 located on the front surface of the pressing unit 40, So as not to be closed.

As described above, there is the effect of being fixed to the mounting means 40 by the opening angle and the weight of the upper mold 22 simply by mounting the upper mold 22.

That is, the operator keeps the open state unless the operator closes (closes) the upper mold 22 by the own weight of the upper mold 22 and the mounting structure of the mounting means 40.

After opening the mold 2 through the above-described structure, the upper mold 22 is prevented from being closed during the operation of supplying the material for manufacturing the O-ring or removing the molded O-ring, thereby securing the safety of the operator .

The mold transfer unit 3 includes a mold plate 31 capable of replacing or fixing the mold 2 so that the mold 2 can be removed and attached and a guide 34 for moving the mold plate 31 And a transfer plate 32 formed on the transfer plate 32. The mold plate 31 is connected to the upper portion of the transfer plate 32 through a guide 34 so as to be transferable.

Thus, the mold plate 31 to which the mold 2 is fixed can be moved along the guide 33 of the transfer plate 32 by moving the operator after the pressurizing portion 11 is raised or by using a cylinder or a servo motor or the like And is moved by a predetermined distance from the lower portion of the pressing portion 11 as in the case of 201A.

Accordingly, when the upper mold 22 is lifted around the rotary shaft 24 as in 201B and the upper mold 22 is opened to the outside of the pressing portion 11 when the mold 2 is opened, The upper part of the mold 2 is not covered, so that the worker's activity is guaranteed.
