Abstract

A blowing mold array includes a blowing mold unit forming a cavity, inside of which plastic preforms are expanded to plastic containers. The blow mold unit includes a blowing mold retainer having at least two mold retainer elements for accommodating parts of the blowing mold unit, and a locking mechanism to arrest at least one part of the blowing mold unit against at least one mold retainer element. The locking mechanism includes an engagement element that can be pivoted and/or shifted relative to a default axis, which in an arrested state abuts a segment of a part of the blowing mold unit. The locking mechanism has an actuating element to loosen the arrest between the mold retaining element and the blowing mold unit. Actuation of the actuating element is coupled with actuation of the engagement element.
