Patent number: 9186818Abstract: Heating device for preforms, capable of accurate and highly localized heating of the preforms before the blow molding step of the process of producing bottles or containers from plastic materials. This device comprises two or more heating modules (11-16), each comprising a through opening (100) in the direction of the thickness of the heating module and a heating element (5) positioned in the vicinity of the through opening. The modules (11-16) are assembled such that the through openings (100) are aligned reciprocally with each other to define a conditioning cavity for the heating device (1). Each heating module (11-16) comprises induction means (2).Type: GrantFiled: October 12, 2011Date of Patent: November 17, 2015Assignee: S.I.P.A.

Publication number: 20080296801Abstract: A device and process for conditioning plastic preforms (5) comprising a cooling turret (6) featuring faces fitted with many holders (7) for conditioning preforms (5). This turret rotates around a horizontal axis (X) and carries out a vertical traverse between a top position under an arm (3), which unloads the preforms from the mould, and a bottom position near the table for extracting the preforms (5) from the turret (6). Tie structure of the turret consists of two parallel bars (18, 19) and several joining plates (14) to which the bases of the holders (7) are attached.Type: ApplicationFiled: October 6, 2004Publication date: December 4, 2008Applicant: S.I.P.A.

Patent number: 7425124Abstract: A device for compression moulding of plastic objects, comprising a plurality of compression-moulding units (9), each of which comprises a core mould element and a moulding cavity (2) filled by dropping into it a dose of plastic material; each moulding unit (9) is designed to carry out a moulding sequence comprising an operation of opening of the mould, an operation of filling of the moulding cavity, and an operation of closing of the mould. The device further comprises cam mechanisms for taking the moulding cavity outside of the vertical axes of the positive-mould element between the operation of opening of the mould and the operation of filling of the moulding cavity. The invention further relates to a method for the production of plastic objects by means of compression moulding device as described above.Type: GrantFiled: December 5, 2002Date of Patent: September 16, 2008Assignee: S.I.P.A.

Patent number: 7335011Abstract: A compression-moulding press for moulding plastic containers (P) consisting of a moulding cavity formed by a plunger (5), a female mould (14), and two separable lips (7, 8). A cylinder (16) slides inside a sliding slide (22) to keep the lips (7, 8) closed. The plunger (5) slides inside the cylinder (16), with respect to both the cylinder (16) and the slide (22), when moulding the containers (P). Finally, a method for making plastic containers by means of compression moulding using said device is also described.Type: GrantFiled: February 27, 2003Date of Patent: February 26, 2008Assignee: S.I.P.A.

Publication number: 20080014295Abstract: A device and process for extracting plastic preforms (5) from holders. Said device comprises a plate (23), which features straight slits (26) positioned parallel to each other, that is attached to a supporting table (20, 21). Each slit (26) comprises wider sections and constrictions (29, 30), which have a width (L2) smaller than the diameter of the ring (9) of the preform, so that the ring (9) can be fitted into the slit (26) through the wider section. The plate (23) is moved in the direction <<D>> by a specific length until the constrictions are positioned under the ring, and, thus, the preforms are removed by moving the plate away from the holders.Type: ApplicationFiled: October 5, 2004Publication date: January 17, 2008Applicant: S.I.P.A.

Patent number: 7163390Abstract: In the molding of parisons made of thermoplastic material for making bottles for containing effervescent beverages, resistance to bursting of the bottles is increased considerably the gasket (4) between the injector nozzle (3) and the injection cavity (1) is made of thermally insulating material and has a shape that is complementary to the shape of the cavity (1) for housing the end of the injector (3) in the injection cavity (1). Cutting of the sprue in specific conditions increases still more the resistance to bursting.Type: GrantFiled: November 26, 2002Date of Patent: January 16, 2007Assignee: S.I.P.A.

Patent number: 7004748Abstract: A fixing device for moulds for plastic articles, where a pair of half-moulds (3, 4) in which a force plug (11) can be inserted, comprises at least one tie rod (6) for keeping the two half-moulds in a closed position, the said tie rod being hinged, at one end, to the mobile half-mould and having a second end of a hammer-headed shape which hooks to two gripping jaws (60, 61). The tie rod (6) is hinged to a connecting rod which rotates on a pivot fixed to the resting base (14), which, in the movement of rotation, sets the tie rod (6) along the line corresponding to the centroid of the pressure forces produced during the moulding operation.Type: GrantFiled: April 5, 2002Date of Patent: February 28, 2006Assignee: S.I.P.A.
