    • A moulding machine comprises first and second non-complementary moulds (20a, 20b). The first mould (20a) defines a female mould cavity (36). The second mould (20b) defines a flat moulding surface (30). The first and second moulds (20a, 20b) are movable between a first position in which the moulds are apart and the female mould cavity (36) and the flat moulding surface (30) both face upwards, and a second position in which the moulds are brought together and the flat moulding surface faces into and closes the female mould cavity to form a completely enclosed cavity. Each mould (20a, 20b) has a plurality of bores (22) formed through it and with an opening (24) at each end. At least two of the bores (22) are connected to each other by a block (38) positioned over the opening at one end of one bore and the opening at the end of another bore. The block (38) is formed with a groove (40) which connects the openings to each other.
    • 成型机包括第一和第二非互补模具(20a,20b)。 第一模具(20a)限定阴模腔(36)。 第二模具(20b)限定平坦的模制表面(30)。 第一和第二模具(20a,20b)可以在模具分开的第一位置和阴模腔(36)和平坦成型表面(30)都朝上的第一位置和第二位置之间移动,其中模具 被带到一起,并且平坦的成型表面面向并关闭阴模腔以形成完全封闭的空腔。 每个模具(20a,20b)具有穿过其形成的多个孔(22),并且在每一端具有开口(24)。 孔(22)中的至少两个通过位于一个孔的一端处的开口上方的块(38)并且在另一个孔的端部处的开口彼此连接。 块(38)形成有将开口彼此连接的凹槽(40)。

    • Die Erfindung bezieht sich auf das Spritzgiessen von Kunststoffartikeln. In einem Formenteil (10) eines Formwerkzeugs sind Heizkanäle (16) und Kühlkanäle (14) ausgebildet, wobei die Kühlkanäle (14) nahe einer Kavitätenoberfläche (12) des Formwerkzeugs angeordnet sind. Heizkanäle (16) befinden sich in grösserer Entfernung von der Kavitätenoberfläche (12) hinter den Kühlkanälen (14). Das Formenteil (10) wird vorzugsweise in einem Spritzgiessverfahren zum Herstellen von Kunststoffartikeln (20) mit einem Kühlprozess verwendet. Dabei wird die Kavitätenoberfläche (12) über den Heizkanal (16) vor dem Einspritzen über die Entformungstemperatur des zu verarbeitenden Kunststoffs erhitzt. Während des Einspritzens kann der Heizkanal (16) weiterbetrieben werden, oder seine Temperatur wird abgesenkt. Mit Beendigung des Einspritzvorgangs wird die Kavitätenoberfläche (12) durch Betrieb des Kühlkanals (14) abgekühlt.

    • The invention relates to a neck block of a mold for producing a hollow preform in an injection molding process. Said neck block comprises a base (10) with a shaping surface which is adapted to the outer contour of a neck section of the hollow preform that is to be produced and is to enter in contact with the neck section of the hollow preform during the injection molding process. At least one cooling duct (11) for a cooling fluid, at least some sections of which extend substantially parallel to the shaping surface, an inlet, an outlet, a supply duct and a discharge duct that connect the inlet or the outlet to the cooling duct are also provided, the cooling duct being disposed closer to the shaping surface than the inlet and the outlet. In order to create a neck block which is easy and thus inexpensive to produce while allowing for effective and homogeneous cooling especially in the vicinity of the shaping surface of the neck block, the cooling duct (11) encompasses at least one section that runs essentially parallel to the shaping surface and extends within the base (10) such that the walls of said section are formed by the base, and a connecting section (13) which adjoins said section and whose walls are formed in part by the base and in part by a closing element that is placed on the base.
