摘要:
A mold 100 for producing a metal-resin composite by press-forming a metal member 10 and integrally molding the metal member 10 that is press-formed and a resin material includes an upper mold 110 and a lower mold 120 that sandwich the metal member 10 and the resin material. The upper mold 110 includes a first press surface 111a for press-forming the metal member 10 and a second press surface 111b for integrally molding the metal member 10 and the resin material. A distance d11 between the first press surface 111a and the lower mold 120 is shorter than a distance d12 between the second press surface 111b and the lower mold 120.
摘要:
A female mold (20) of an in-mold injection molding mold device (1) has a first suction hole (31), a second suction hole (32), and a concave suction groove (33). The first suction hole (31) opens in a bottom surface (22) of a cavity (21) of the female mold (20). The second suction hole (32) opens in a part, to the inside of a clamper (40), of a clamping surface (25) of the female mold (20) on which a male mold (10) abuts, with a decoration film (100) held therebetween. The suction groove (33) is formed on a front surface of the female mold (20) so as to make the cavity (21) and the second suction hole (32) communicate with each other. The first suction hole (31), the second suction hole (32), and the suction groove (33) function as exhaust paths when air in a space (SA) between cavity surfaces (22, 23, and 24) defining the cavity (21) and the decoration film (100) is being discharged.
摘要:
A method for obtaining a heat-insulating and sound-absorbing composite product consisting in a fibrous material (MF) and in a polymeric material (MP) comprises the steps of positioning the fibrous material (MF) in a mould (1) equipped with a cavity that is only partially filled in a central zone thereof, overlapping polymeric material (MP) to the fibrous material (MF), approaching a counter-mould (3) provide with a counter-cavity (4) to the mould (1), expanding of the polymeric material (MP) by chemical reaction, forming the composite positioned between mold (1) and counter-mould (3), removing the counter-mould (3) from the mould (1) and extracting a product. After the step of forming the polymeric material (MP) covers the fibrous material (MF) in the central zone of the cavity and fills a peripheral groove (7) of the cavity of the mold (1). Further, a moulding equipment and the product so obtained are described.
摘要:
Zur Herstellung eines Formteils (1), insbesondere Behälters, aus Kunststoff durch Rotationsformen, wird ein Kunststoffvorläufer des für das Kunststoffformteil (1) vorgesehenen Kunststoffs in eine Rotationsschmelzform (9) eingebracht, wobei der Kunststoffvorläufer als Schmelze in der Rotationsschmelzform (9) vorliegt und unter Rotation der Rotationschmelzform (9) bei gleichzeitiger Formgebung auspolymerisiert. Das Verfahren umfasst die folgenden Schritte: a) Einsetzen eines Einlegeelements aus einem saugfähigen und/oder tränkbaren Material in die Rotationschmelzform (9); b) Einbringen des Kunststoffvorläufers in die Rotationsschmelzform (9); c) Versetzen der Rotationsschmelzform (9) in Rotation, so dass ein Teil der Schmelze von dem Einlegeelement aufgenommen wird.
摘要:
A mould for forming a motor vehicle part from a polymer material (17) comprising at least a metal insert (15, 27, 29, 31) that is partially overmoulded, i.e. having a portion (15b, 27b, 29b) intended to be covered with polymer material and a portion not intended to be covered with polymer material. The insert comprises an overmoulding limit (15c, 27c, 29c) and the mould comprises a mobile portion (11, 50) capable of sliding with little clearance.
