吹塑模具阵列、拉伸吹塑机和方法
摘要：
本发明涉及用于将塑料预制件重注塑成塑料容器的吹塑模具阵列，包括吹塑模具单元(2)，所述吹塑模具单元(2)形成腔(8)，所述塑料预制件在所述腔(8)中膨胀成塑料容器，其中所述吹塑模具单元(2)是至少两件套(two-piece)单元。所述吹塑模具阵列(1)包括用于容纳所述吹塑模具单元的吹塑模具支撑(4)，其中所述吹塑模具支撑(4)具有用于容纳所述吹塑模具单元(2)的部分(2a，2b)的至少两个模具支撑件(4a，4b)，所述吹塑模具阵列(1)还包括锁定机构(10)以相对于至少一个模具支撑件(4a)制动所述吹塑模具单元(2)的至少一部分(2a)，所述锁定机构(10)包括可相对于默认轴线(X)枢转或移位的啮合件(12)，在所述吹塑模具单元(2)的一部分(2a)相对于所述模具支撑件(4a)制动的情况下，所述啮合件(12)推挤所述吹塑模具单元(2)的所述部分(2a)的一段。根据本发明，所述锁定机构包括启动件(14)以释放所述模具支撑件(4a)和所述吹塑模具单元(2)之间的制动，其中所述启动件(14)的启动与所述啮合件(12)的运动耦连。
摘要（英）：

The invention relates to a blowing mold array (1) for re-molding plastic preforms into plastic containers comprising a blowing mold unit (2) forming a cavity (8), inside of which the plastic preforms can be expanded to plastic containers, wherein the blowing mold unit (2) is at least a two-piece unit, and having a blowing mold retainer (4) for accommodating the blowing mold unit, wherein the blowing mold retainer (4) has at least two mold retainer elements (4a, 4b) for accommodating parts (2a, 2b) of the blowing mold unit (2), and having a locking mechanism (10) in order to arrest at least one part (2a) of the blowing mold unit (2) against at least one mold retainer element (4a), wherein the locking mechanism (10) is provided with an engagement element (12) that can be pivoted and/or shifted relative to a default axis (X), which in an arrested state of the part (2a); of the blowing mold unit (2) opposite a mold retaining element (4a) abuts a segment of the part (2a) of the blowing mold unit (2). According to the invention, the locking mechanism (10) is provided with an actuating element (14) in order to loosen the arrest between the mold retaining element (4a) and the blowing mold unit (2), and an actuation of said actuating element (14) is coupled with the actuation of the engagement element (12).
