中型３との間で材料Ｍを圧縮成形する。 The leveling device of the present invention is used for this leveling work of the upper surface. The leveling device is indicated generally at 10 and includes a support plate 11 and a number of leveling needles 12. The support plate 11 is supported by a rod 13 on a leveling head 14 which is vertically movable.
The leveling head 14 has a built-in vibration source (not shown), such as a vibration motor. Therefore, the leveling needle 12 vibrates due to the horizontal vibration action of the vibration source, and its tip (lower end) levels the upper surface of the material M. After the break-in work is completed, the head 14 rises, and then a press ram (not shown) descends into each space 2, 2,
The material M is compression molded between the medium mold 3 and the medium mold 3.

１２が固定される。 As shown in FIG. 2, the leveling needle 12 has an enlarged plate-shaped head 22, and the leveling needle is inserted from above into the insertion hole 21 of the removed lower plate. As a result, the head 22 comes into contact with the upper surface of the upper plate 17. In this state, the lower plate 17 is attached to the lower surface of the upper plate 16 with the elastic plate 18 in between, and bolts are inserted into holes (not shown) in the upper plate 16 that align with the bolt holes 20 and tightened removably. The elastic plate 18 presses the head 22 of the leveling needle against the lower plate 17, and the leveling needle 12 is fixed.

板１７を取外して直ちに光換することができる。 The number and insertion position of the break-in needles 12 are adjusted to be optimal according to break-in conditions.
For example, when the surface area of the material M is small, the leveling needle 12 is inserted into the insertion hole 21 near the center, and when the surface area is large, the insertion hole 21 is inserted over the entire surface of the lower plate 17.
The leveling needle 12 is inserted through the hole, and the insertion density and pattern of the leveling needle 21 can be freely adjusted. Furthermore, when the leveling needle 12 is damaged, the lower plate 17 can be removed and light exchanged immediately.
