Abstract:
The invention relates to a mounting device (1) for a center part (4) rotatable about a rotary axis (6) in an injection molding device. The mounting device comprises at least one lower mounting device (2) having a modularly constructed lower cross member (7). The cross member (7) comprises a center block (9) and at least one side block (11) fastened to the center block (9). The center block (9) comprises operative connection means for fastening a lower rotary unit (24) for rotatably mounting the center part (4) about rotary axis (6).
Abstract:
A device (1) and method for injection molding articles (25) with several plastic material components. The device (1) includes a fixed, first half mold (3), a second half-mold (6) that is movable relative to the first half-mold (3) for the purpose of opening and closing the device (1). The device also includes at least two further half-molds (10, 11), which are jointly movable relative to the first and second half-molds (3, 6), and which, in the closed position of the device (1), are situated between the first and the second half-molds (3, 6) such that cavities are formed in each of a first and a second parting plane (32, 33). The two further half-molds (10, 11), which are jointly movable, include a device (22), which in the case of an opened device (1) serves to transport the article (25) out of a first cavity (21.1) into a second cavity (21.2) so that the article (25) can be injection molded around with a further material component in the second cavity (21.2).
Abstract:
The invention relates to a device (1) for producing hinged closures out of plastic. The device (1) has a prismatic central block (3) which can be rotated about a rotational axis (2), said block being arranged between a first and a second molding plate (4, 5). The first and the second molding plates (4, 5) are movable in relation to the central block (3) in a first direction, and in a closed position, form a plurality of cavities in the area of a first and a second parting plane. The device has a handling system (14) used to remove and transport the hinged closures onto a capping device (16) in accordance with their layout.
Abstract:
A method of making an injection molded device includes the steps of (a) assembling a mold comprising a primary male mold half and a primary female mold half to define a primary mold cavity; (b) injecting a first fluid polymeric material into the primary mold cavity and permitting the first fluid polymeric material to solidify to form a device frame; (c) replacing the primary female mold half with a secondary female mold half; (d) restraining the device frame in the resulting mold cavity and injecting a second fluid polymeric material to form a first portion of an outer layer that retains the shape of the first overmold cavity; (e) replacing the primary male mold half with a secondary male mold half; and (f) injecting an additional amount of the second fluid polymeric material into the resulting cavity to form a sufficiently integral outer layer about the device frame.

Abstract:
The present invention is directed to a modular mold system comprising at least two mold designs or mold sizes. In a further embodiment, the present invention is directed to a modular mold system comprising molds that are the same design but vary in size and cavitation. In a further embodiment, the present invention is directed toward a modular mold system for production of a family of a part designs. In a further embodiment, the present invention is directed toward a modular mold system developed from a part design and a part size. Another embodiment of the present invention would be directed toward a modular mold system comprising at least two mold sizes comprising standardized and identical components.
Abstract:
The invention concerns a device for injection molding comprising a first fixed half-mold and a second half-mold mobile in direction (y) of the side blocks of an injection molding machine. Between the first and the second half-molds are mounted first and second intermediate elements mobile in the direction of the side blocks. The first and the second intermediate elements comprise each a mold support pivoting relative to a base about s pivoting axis. Centering elements are used to center the intermediate elements relative to the half-molds upon the opening and closure of the injection molding device.
Abstract:
The invention relates to a device and a method for producing plastic moldings from at least two different sub-elements (15; 16) that includes first and second mold halves (3) and a rotatable center block (6) with center and third mold halves (8; 17) interposed therebetween. The center and third mold halves define first and second parting planes with the first and second mold halves. First cavities are defined in the first parting plane, into which a first plastic component is introduced to produce preforms (12). When the first parting plane is opened, the performs (12) remain on the center mold halves (8) and are brought into the second parting plane when the center block (6) is rotated, in which second parting plane second cavities are at least partially defined by the preforms (12), into which a second plastic component is introduced and first sub-elements (15) are produced. Second sub-elements (16) are produced in the additional cavities. When the second parting plane is opened, the sub-elements (15; 16) remain on the center and third mold halves (8) and are rotated into a lateral assembly position when the center block (6) is rotated.
