    • An apparatus for compression-moulding preforms from a dose (D) of plastics comprises punch means (12), die means (13) provided with a cavity and at least two die elements (22) which are mutually movable between a contact position and a detached position. The punch means (12) comprising a punch (14) suitable for being inserted into the cavity and a pressing sleeve (31) mounted slidably around the punch (14) to maintain said at least two die elements (22) in said contact position. The punch means (12) further comprises jacket means (91) arranged for receiving said punch (14) and said pressing sleeve (31) and at least a first chamber (42, 57), containing a first fluid at a first pressure and acting on said pressing sleeve (31), which is entirely bounded by said pressing sleeve (31) and by said jacket means (91) so as to enable said punch to be dismantled from said punch means (12), maintaining said first chamber (42, 57) pressurised.
    • 一种用于从塑料剂量(D)压缩成型的预成型件的设备包括冲压装置(12),具有空腔的模具装置(13)和至少两个模具元件(22),它们可在接触位置和 分离位置。 冲头装置(12)包括适于插入空腔的冲头(14)和可围绕冲头(14)可滑动地安装的按压套筒(31),以将所述至少两个模具元件(22)保持在所述接触位置。 冲压装置(12)还包括套管装置(91),用于容纳所述冲头(14)和所述按压套筒(31)和至少第一腔室(42,57),所述第一腔室包含第一压力的第一流体, 在由所述按压套筒(31)和所述夹套装置(91)完全限定的所述按压套筒(31)上,以使所述冲头能够从所述冲压装置(12)中拆下,从而保持所述第一腔室 ,57)加压。
