Abstract:
A method for forming a part in an injection mold, includes: heating a molding material to a molding temperature; injecting the molding material through a gate and into a molding cavity of the injection molding apparatus of any of the preceding claims; pressing the stationary half and the moving half together to form the molding cavity between the resin mold surface and the insert molding surface; moving the movable mold insert, and thereby moving the insert molding surface and adjusting the molding cavity shape, the molding cavity depth, the molding cavity volume, or a combination comprising at least one of the foregoing along at least a portion of the molding cavity; cooling a surface of the molding cavity with the cooling system; separating the resin mold surface and the moving half mold surface; and ejecting the part from the injection molding apparatus.
Abstract:
An injection molding tool for producing plastic parts such as toothbrush bodies is disclosed. The tool has a center mold block (10) and a pair of outer mold blocks (12,14). The center mold block has two parallel opposed molding faces (10a) joined by two parallel opposed side faces (10b) extending perpendicular to the molding faces. The molding faces have parallel partial mold cavities formed therein and the outer mold blocks each are associated with one mold face of the center mold block and each have a molding face with parallel partial mold cavities formed therein which together with corresponding partial mold cavities of the associated mold face of the center mold block form complete mold cavities for molding the toothbrush bodies when the outer mold blocks are positioned close to the center mold block. Each molding face of the center mold block has a pair of recesses for accommodation of movable inserts (20,22) which have fractions of the partial mold cavities formed therein. When the outer mold blocks are separated from the center mold block, the inserts are moved with indexing steps alongside the two opposed molding faces, alongside the side faces and around the corners formed between the molding faces and the side faces of the center mold block.
Abstract:
Disclosed is a method for producing reinforced plastic parts, comprising the steps of: a) providing at least one reinforcing material in a cavity (16, 24, 43) of a mold (11, 21, 41); b) providing at least one starting material in a container (100); c) inserting the container into the mold; d) introducing the at least one starting material from the container into the cavity such that the at least one reinforcing material is penetrated at least in part by the at least one starting material; e) hardening the at least one starting material along with the at least one reinforcing material so as to obtain a reinforced plastic part; and f) removing the reinforced plastic part from the mold. Also disclosed is an apparatus for producing reinforced plastic parts, comprising at least one cavity (16, 24, 43) of a mold (11, 21, 41), a receiving device for at least one container (100), a discharging device and a mixing unit (3).
Abstract:

Abstract:
A method for producing a tube blank from two different plastics (A, B) and with the aid of an injection mould (1), wherein, in a first step, a tube body (38) is injection-moulded from a first plastics material (A) at a first temperature T 1 with an asymmetric spider-like sprue (15) arranged above the tube body. In a further step, a cover part (12) is moulded onto this asymmetric spider-like sprue from a second plastics material (B) at a second temperature T 2 in such a way that the two plastics materials (A, B) enter into an interlocking and material-bonding connection. An injection mould 1 suitable for this comprises three main components (41, 42, 43) that are movable with respect to one another, namely a first station (41), for the injection moulding at a first temperature T 1 of a tube blank (37) with an asymmetric spider-like sprue (15) arranged above the tube body (38), a second station (42), for the moulding of a cover part (12) at a second temperature T 2 onto the asymmetric spider-like sprue (15) and this tube body (38), and a central station (43), which is arranged rotatably between these two stations (41, 42) and forms with the first station (41) a mould cavity (9) for the injection moulding of a tube body (38) with an asymmetric spider-like sprue (15) arranged above the tube body. After turning through 180°, the central station (43) forms with the second station (42) a mould cavity (23) for the moulding on of the cover part (12) in an interlocking and material-bonding manner. The tube blank (37) produced in this way comprises a tube body (38) and an asymmetrical spider-like sprue (15) arranged above the tube body (38), of a first material (A), and a cover part (12), of a second material (B), connected thereto in an interlocking and material-bonding manner. The cover part (12) and the tube body (38) are connected to each other in an interlocking and material-bonding manner in the region of a connecting zone (21) in the form of a tongue-and-groove joint.
