DEVICE FOR MOLDING SEMICONDUCTOR PACKAGE
A device for molding a semiconductor package including an upper mold configured to retain a substrate thereon, the substrate having semiconductor chips thereon, a lower mold defining a cavity and including a plurality of moving blocks, a bottom surface of the cavity defined by the moving blocks, the cavity configured to contain a molding resin, the moving blocks movably arranged under the cavity, a driving unit configured to movably drive the moving blocks, and a controller configured to control an raising order of the moving blocks by controlling the driving unit may be provided.
Device and method for producing injection-molded parts which comprise different components
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.
Thick plastic part and method of making and tool
In some embodiments, a tool includes, in an injection molding machine, a movable internal core configured to receive a molded plastic layer thereon, the molded plastic layer having a thickness. The tool also comprises an injection nozzle configured to inject plastic material over the movable internal core to form the molded plastic layer; an ejection plate connected to the movable internal core; and multiple, movable support plates each having a thickness. The multiple, movable support plates are located behind the ejection plate. A movable support plate of the multiple, movable support plates is configured to determine the thickness of the molded plastic layer.

DEVICE FOR MANUFACTURING INNER TRIM ELEMENTS
A device for manufacturing inner trim elements which are formed by a rigid carrier and a cover layer, between which elements a polymer foam layer is arranged. The carrier is fixable on a first moulding tool element, and the cover layer is fixable between the outer edge of the first moulding tool element and the outer edge of a second moulding tool element. In the moulding tool, a cavity is formed between the carrier and the cover layer, wherein a foamable polymer is introducible into the cavity via at least one through-hole which is formed in the carrier and the first moulding tool element. The distance between the first and the second moulding tool element is enlargeable during the foaming process. At least one through-hole for an escape of air and reactively formed gases out of the cavity is formed in the carrier and in the first moulding tool element.
