摘要:
A blow mould for containers wherein the mould base comprises a first member (5) and a second member (6) connectable to each other by means of a quick coupling system comprising at least one first connection pin, wherein said second member (6) includes a first slider (13), defining a first sliding direction on a plane orthogonal to the longitudinal axis of the mould and capable of taking an unlocking position and a locking position, said first slider (13) being provided with at least a hole in order to lock the first connection pin when the first slider (13) is in the locking position, and a second slider (16) defining a second sliding direction on said plane, intersecting said first direction; said second slider (16) being slidable along said second direction from a position of mechanical connection with the first slider (13) to a position of releasing from said first slider.
摘要:
A method of blow molding a glossy article having at least one layer of thermoplastic material. The method comprises the steps of feeding a parison of said thermoplastic material into a mold having an inner surface with at least a portion of SPI finish standard selected from the group consisting of A-1, A-2, A-3, B-1, B-2 and B-3 mold and a first temperature of greater than 55° C.; blowing the parison against the inner surface of the mold to form the article; and subsequently lowering the temperature of the mold to a second temperature of between 10° C. to 55° C. before release of the molded article. The cycle time of the mold (tct) is less than 250 seconds.

A method of molding a large returnable container (40) includes a heat treatment step that includes subjecting a thick preform (10) formed of a polyester resin, or a primary blow-molded article (20) obtained by subjecting the preform to primary blow molding, to intermediate blow molding with heating to obtain an intermediate molded article (30) from which a strain that has occurred during blow molding has been removed, and a final blow molding step that includes subjecting the intermediate molded article that has shrunk to final blow molding with heating to obtain a large returnable container. The heat treatment step includes disposing the preform or the primary blow-molded article in a heat treatment mold (204), and pressurizing the preform or the primary blow-molded article by introducing high-pressure air into the preform or the primary blow-molded article so that a shoulder (22) and a body (24) obtained by blow molding close contact to a cavity surface (204A) of the heat treatment mold, and are subjected to a heat treatment, the shoulder (22) being heated at a low temperature as compared with the body (24).

Unité de moulage pour le formage d'un récipient ( 2 ) muni d'une réserve (3) en creux vers l'intérieur du récipient ( 2 ), cette unité de formage comprenant : - un moule ( 5 ) muni d'une paroi ( 6 ) latérale définissant une cavité ( 7 ) à l'empreinte d'au moins une partie du récipient ( 2 ), pourvue d'un logement ( 9 ) formé en creux dans une excroissance ( 10 ) formant une saillie vers l'intérieur de la cavité ( 7 ) et débouchant dans la cavité ( 7 ) ; - un dispositif ( 11 ) de boxage comprenant un insert ( 12 ) monté en translation par rapport à la paroi ( 6 ) latérale entre une position rétractée dans laquelle l'insert ( 12 ) est escamoté dans le logement ( 9 ), et une position déployée dans laquelle l'insert ( 12 ) fait saillie hors du logement ( 9 ), saillie dont l'extension transversale est inférieure ou égale à 85% de l'extension transversale cumulée de l'excroissance ( 10 ) et de l'insert ( 12 ).
摘要:
Method to manufacture a container includes disposing a first parison within a first mold assembly having a first inner surface defining a first mold chamber. The first mold assembly includes at least one first insert disposed on the first inner surface within the first mold chamber. The first parison is blow molded to form a first container body within the first mold chamber, wherein at least one first portion of the first container body corresponding to the at least one first insert has a first portion temperature greater than a remaining portion of the first container body. The at least one first portion of the first container body can be contacted to at least one second portion of a second container body to attach the first and second container bodies. Assemblies, systems, and intermediate stage pre-assembly multi-chamber containers are also disclosed, as well as multi-chamber containers formed from the same.
