    • Method for manufacturing plastic preforms (10) by injection moulding, consisting of sub-preforms (11, 12) injected at the same time, wherein (Φ1) the injection mould (3) containing the injected composite preform (10) and secondary sub-preform (12) is 1 st closed, and a gripper (4) provided with a set of receiving members (16) is set in a standby position (A) aside from the mould (3); in a 2nd step (Φ2) the mould (3) is opened, wherein each primary core (33) bears an injected composite preform (1 0), and the secondary core (33') a secondary inner preform (12); the gripper (4) is then driven (Φ3) in motion between the standby position (A) and a take-over position (B), wherein the injected preforms (10, 12) are cooled and taken over from the core side (31 ) by the gripper (4) by means of suction means (6); wherein the gripper (4) is further moved (Φ4) into a further operating position (C), in which it places the received secondary inner preforms (12) onto the respective primary cores (33) and continues to hold said preforms (11), with formation of integrated preforms (10) which are expelled to a discharge unit.
    • 用于通过注射成型制造塑料预制件(10)的方法,其由同时注入的子预成型件(11,12)组成,其中(Φ1)包含注入的复合预成型件(10)的注塑模具(3) 预成型件(12)第一闭合,设置有一组接收构件(16)的夹具(4)设置在与模具(3)相对的待机位置(A)上。 在第二步骤(Φ2)中,打开模具(3),其中每个初级芯(33)承载注入的复合预制件(10),次级芯(33')承载次级内预制件(12)。 然后在待机位置(A)和接收位置(B)之间运动夹持器(4),其中喷射的预成型件(10,12)被冷却并从芯侧(31) )通过抽吸装置(6)由夹持器(4)传送; 其中所述夹持器(4)进一步移动(Φ4)到另一操作位置(C)中,其中将所述夹持器(4)放置在相应的初级芯(33)上并且继续保持所述预成型件(11) 形成一体的预成型件(10),其被排出到排出单元。
