Abstract

The present invention relates to a transfer mold capable of multi-row press work, wherein reference plates are formed in a plurality of lines and materials which are located on each reference plate are simultaneously and consecutively moved by a moving member such that a plurality of products can be produced at one time, thereby improving work productivity. Furthermore, since the materials do not move when a punch presses the materials, a defect rate of products is reduced. In addition, oil is supplied to a jig such that a high-temperature heat generated from the materials during the pressing step or the like of the materials is quickly emitted by the oil, thereby preventing the deformation of the materials caused by high temperatures.

parts

59a and 59b. It is connected to the end of the pair of second connecting bar 59 located in the same direction as the other end. In addition, the second connection bar 59 is automatically slid along the longitudinal direction of the second support 56 by the driving of the third driving motor 59c. As a result, the second jig frame 42 is slidably moved in the longitudinal direction and in the vertical direction.

As described above, according to the present invention, the first jig frame 32 and the second jig frame 42 are driven in the longitudinal direction and the horizontal direction of the first, second, and

third driving motors

57c, 58c, and 59c. Since it is configured to move in the direction perpendicular to the direction, the distance between the first and

second jig frame

32, 42 can be moved to be narrowed inward or widened outward, as well as to move along the longitudinal direction. . Accordingly, after the materials 200 positioned on the plurality of reference plates 10 are pressed by the punch 20, the length directions of the reference plates 10 are adjusted by the first and second jig frames 32 and 42. As a result, since it is sequentially moved by a predetermined section, and is repeatedly pressed by the punch 20 again and processed into a desired product shape, productivity of the work is improved.

Referring to the drawings, the conventional transfer mold, when the material 200 is pressed, since the material 200 is not fixed by the jig, when the position of the material 200 is changed due to vibration or external impact, There is a problem that the punch cannot press the material 200 correctly.

In order to solve this problem, the transfer mold of the present invention has a state in which the first and

second jigs

34 and 44 move the material 200 to the shanghai-dong rod 12 of the reference plate 10. After the punch 20 is inserted into the material 200 to prevent the material 200 from being shaken, the first and second jig frames 32 and 42 are outside as shown in FIG. After the first and

second jigs

34 and 44 are spaced apart from the material 200, the punch 20 is configured to press the material 200 as shown in FIG. 6C. As such, the present invention is configured to press the material 200 in a state where the punch 20 is pre-positioned inside the material 200, so that the first and

second jigs

34 and 44 clap the material 200. Even if not, the material 200 is not shaken during the press process, thereby reducing the defective rate of the product.

Referring to FIG. 7, oil may be supplied to the insides of the first and

second jigs

34 and 44 facing each other to dissipate high temperature heat generated in the material 200. To this end,

oil absorbing parts

36 and 46 are provided at lower portions of the first and

second jig

34 and 44, and the

oil absorbing parts

36 and 46 along the inside of the first and second jig frames 32 and 42.

Oil supply nozzles

38 and 48 are provided to supply oil to the oil supply unit, and the oil is supplied to the

oil absorbing units

36 and 46. At this time, the fixing

parts

35 and 45 are inserted in the

oil absorbing parts

36 and 46 in the upper parts of the first and

second jig

34 and 44, and the

oil absorbing parts

36 and 46 are the first and second jig. It is firmly fixed to (34, 44).

In this way, when oil is supplied to the

oil absorbing parts

36 and 46, oil is applied to the first and

second jigs

34 and 44 or the material 200, and thus, during the press process of the material 200 by the punch 20. The high temperature heat generated in the material 200 is quickly released by the oil, and thus, the deformation of the material 200 due to the high temperature is prevented.
