![]() The placement of the ejector pins for bearing against the pin tabs precludes the loading of the interface within the laminate package between the mold cap and the chip/substrate assembly. The die further provides for an ejector pin hole to be located at each ejector pin tab such that the ejector pins, when pressed for release of the laminate package from the mold die, bear against the integrally formed pin tabs rather than against the substrate of the chip/substrate assembly. An advanced mold die provides multiple wells for the formation of ejector pin tabs to be formed integrally to the mold cap of a chip laminate package. The invention is also characterized in that the engaging element (40) is connected to the moveable tool plate (11).Ībstract: An apparatus and method for providing delamination-resistant, array type molding of chip laminate packages such that larger chip array block sizes may be employed. The invention is further characterized in that the toothed disk (22) corresponds to a tubular component (31) which can be driven by the drive unit (61) and which surrounds the spindle (21) in a free moving manner. The invention is characterized in that a toothed disk (22) is secured to one end of the spindle (21), whereby the diameter thereof (D) is greater than the outer diameter (d) of the spindle (21). An engaging element (40) is also provided to enable the spindle (21) to be displaced axially. ![]() The inventive device comprises a drive unit which enables an actuating unit connected to a spindle (21) to be moved both towards and away from the mould in a linear manner. ![]() The molded article receiver includes receiver tubes for receiving the molded articles.Ībstract: The invention relates to a device for removing injection moulded parts from the mould of an injection moulding machine, especially for plastics, provided with a moveable and a fixed tool mounting plate. A power operator, carried by the third mold portion and coupled to the article holding surfaces, is responsive to a signal to move the article holding surfaces from the pre-release position to a full release position when a molded article receiver is suitably positioned to receive the molded articles. The cam follower interacts with the cam track to cause some initial movement of the surfaces holding the molded articles to a pre-release position for the holding surfaces so that the molded articles are loosely retained by the holding surfaces. A cam follower coupled to the surfaces of the third mold portion, which are holding the molded articles, is engaged in the cam track when the second and third mold portions are within a pre-selected distance of each other. Abstract: A release mechanism operating to release molded articles from a third mold portion includes a guide coupled to the second mold portion forming a cam track.
