Molding assemblies and methods for dual side package molding are described. In an embodiment, a molding compound is injected into a front cavity with a first actuator, and a molding compound is injected into a back cavity with a second actuator, with the first and second actuator assemblies being independently controlled. In an embodiment, the molding compound flows through a through-hole in a molding substrate from a front side of the molding substrate to a back side of the molding substrate, and into the back cavity.

摘要:
A feed system for an injection molding method and machine includes a first part including a first channel, and a second part including a second channel, the first channel and the second channel forming a molten plastic feed conduit when the first part is located adjacent to the second part. A joint is formed between the first part and the second part along the first channel and the second channel and the joint is one of a sintered joint, a welded joint, and a brazed joint.
摘要:
A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.
摘要:
An injection mold (9') of a plastic preform comprising a first part (12) and a second part (13), fixed to each other, and a third part (14); wherein the third part (14) is provided with a molding cavity (41') defining an axis (Υ') and is adapted to be integrally fixed to a first surface of a supporting frame of the mold; wherein the second part (13), arranged between the third part and the first part, is adapted to slide along said axis to close or open the cavity; wherein the first part (12) comprises a longitudinal rod (55) adapted to slide along said axis (Υ') through a second surface of the supporting frame, opposite to and spaced apart from the first surface; wherein the second part (13) is provided with: - a guiding cage comprising a first plate (18), provided with a through hole through which the longitudinal rod can slide and configured to abut on said second surface; a structure (18"); parallel guiding rods (16) fixed at a first end thereof to said first plate and fixed at a second end thereof to the structure, - an assembly (19, 18', 49) sliding inside said cage, fixed at a first end thereof to the rod by means of quick-coupling means (15), and comprising at a second end thereof a punch (59) sliding inside the structure and defining a first complementary component of the cavity, wherein the structure (18") is provided with two half-collars (66', 66") and is configured so as to define, together with the punch, a cam system for opening or closing the two half-collars which define, when closed, a second complementary component of the cavity.
