Blow-moulding device with preloadable attachment for blow moulds

A transforming device for transforming plastic preforms into plastic containers, comprising a blow-molding device which forms a cavity inside which the plastic preforms can be transformed into the plastic containers through the application of a flowable medium, wherein the blow-molding device has at least two side parts which are arranged at least indirectly on blow-mold carriers, wherein the side parts are arranged on the blow-mold carriers by an attachment device is provided. The attachment device also has a return which, at least temporarily during a working mode, pushes at least one side part towards the blow-mold carrier on which the side part is arranged.

Process for Molding Hollow Workpieces
20170326768 · 2017-11-16 ·

An apparatus and process for molding workpieces usable for consumer products. The workpieces may be injection molded with a cavity formed by a core pin and have an undercut, such as internal threads, in the cavity. The apparatus has a drive system with a stripper plate mounted for alternatingly forward and retracting axial movement. The stripper plate is axially driven and drives a stripper sleeve barrel cam and a core pin base barrel cam, each having respective cam followers. The respective motions of the cam followers are superimposed on a stripper sleeve insert, which drives a core pin sleeve. The core pin sleeve is subjected to responsive three dimensional motion, allowing an internally threaded workpiece to be unscrewed from the core pin sleeve. The system does not require separate drives for the core pin sleeve, a single stripper plate drive being sufficient and further allows each mold cavity/core pin combination in a mold half to be unique.

METHOD FOR FORMING CONTAINERS WITH MULTIPLE WALLS
20170312979 · 2017-11-02 ·

Disclosed is a for forming a container with multiple walls by blow molding or stretch blow molding of a preform, including a blow-molding phase followed by a degassing phase, beginning at a moment, of the formed container, to bring t:s pressure back to the ambient pressure. The method also includes: a continuous measurement of the pressure prevailing in the neck during the degassing phase; the determination of the length of time that has elapsed between the beginning of the degassing and the attaining of a reference pressure in the neck; the comparison of the length of time that has elapsed with a theoretical length of time that is necessary so that the reference pressure is attained in the neck; and maintaining the locking of the mold if the length of time that has elapsed is less than the theoretical length of time.

MOLDS, MOLD ASSEMBLIES AND STACK COMPONENTS

A cavity plate assembly (400) for a preform mold (100), which includes a cavity plate (410) having an array of seats (412) and a corresponding array of cavity inserts (440) mounted to a front face (CVF) of the cavity plate (410) and in communication with a respective seat (412). Each cavity insert (440) includes a body (441) with a mounting face (441a) and a spigot (443) projecting from the mounting face (441a) and received in a respective seat (412) of the cavity plate (410) such that the mounting (441a) face abuts the front face (CVF) of the cavity plate (410).
