Among them, when the upper pressing die 9 stops at the lowest position, the downward pressure is maintained for a period of time. The retention time can be set in advance in the controller 5, and the control time is set according to product requirements.

[0029] In another optional embodiment, a linear driving component such as a driving oil cylinder or a linear push rod may be used to replace the driving cylinder 3 .

[0030] like Figure 1As shown, in order to facilitate the adjustment of the position of the upper die 9 relative to the lower die 10, the upper part of the upper die 9 is connected to the lower end of the pressure rod 8, and the upper part of the pressure rod 8 is tightly connected to two clamping blocks 27, and the two clamping blocks 27 are detachably connected to the lifting plate 7 through a connecting piece, and the upper end of the lifting plate 7 is connected to the front end of the driving rod of the driving cylinder 3.
