The invention relates to a retaining device (5) for a rotatable center block (17) in an injection molding device (1), comprising a lower rotary plate (14) rotatable about an axis of rotation (13) and driven by a motor (15), the lower rotary plate being used for retaining the rotatable center block (17). The retaining device (5) comprises a lower cross member (7), which is mounted movably in the longitudinal direction (x) on guide rails (9) while supported on a machine bed of the injection molding device by means of first bearing blocks (8). The retaining device (5) can have two bearing blocks (16), by means of which the lower cross member (7) is supported in the circumferential direction relative to lower beams (4) of the injection molding device. For a further increase in efficiency, the center block (17) has a main body made of a material of lower density than a coupling plate (23) operatively connected thereto.

Glove box bin with adjustable stiffness

A vehicular glove box bin has a molded substrate of a first durometer plastic material defining a concave body with bin sides, bottom, and open mouth. The sides include a front wall arranged to receive an impact load in a substantially normal direction, and at least one perforated wall substantially aligned with the normal direction which has at least one stiffness reducing gap. A substitution panel comprising a resilient material having a second durometer less than the first durometer is molded into and closes the gap. The gap and the substitution panel define locking surfaces for retaining the substitution panel. The combined first and second durometers provide a predetermined collapse in response to the impact load. The placement and sizes of gaps together with the selected durometers allow a designer to tailor the stiffness around various portions of the bin to match a desired impact performance.

An injection molding method includes providing a molding device including a first mold, a second mold over the first mold and a first mold cavity defined by the first mold and the second mold; injecting a first material into the first mold cavity; forming a first layer from the first material; replacing the second mold by a third mold; injecting a second material into a second mold cavity defined by the first mold and the third mold; and forming a second layer from the second material disposed over the first layer, wherein the first material is different from the second material.

Packaging system with an overcap

An overcap for a roast and ground coffee container is disclosed. The overcap can include a gasket as an airtight seal between the overcap and the container that preserves a clicking sound upon closure by an end user and an outer portion that gives an end user a visual and touchable stimulus.

METHOD FOR MOLDING A PART, FOR EXAMPLE FOR VEHICLE INTERIORS, TYPICALLY A DASHBOARD AND/OR INTERNAL PANELS, AND CORRESPONDING PART
20180264697 · 2018-09-20 ·

An injection molding method of a part for vehicle interiors includes arranging a mold having a first injection chamber defining in negative a base of the part. Thermoplastic material is injected into the first chamber and the base is extracted from the first chamber and placed in a second injection chamber. A lining film is inserted in the second chamber and deforming it to arrange the film on an outer surface thereof, adhering to an esthetic wall of the second chamber opposite a functional wall. An intermediate plastic layer is injected in a gap between an inner wall of the base facing the lining film, and an inner surface of the lining film opposite the outer surface to create a single sandwich structure. The intermediate layer is between the lining film and the base, has lower hardness than the base and forms a yielding padding for the lining film.

In a three-plate injection-molding machine comprising a nozzle plate, a movable second mold clamping plate, a movable end plate, a closing unit that acts between the end plate and the second mold clamping plate, and a turning unit arranged between the nozzle plate and the second mold clamping plate, rails extend between the nozzle plate and the end plate. The mold-half carrier of the turning unit is supported on a support structure so that it can be rotated about an axis transverse to the machine axis, which support structure forms the abutment for the mold-half carrier rotary drive. The weight of the support structure and mold-half carrier of the turning unit is transferred into the machine bed by means of linear guides, and a substantial part of the reaction torque applied to the support structure is transferred to one of the rails by means of one supporting guide.

CO-INJECTION WITH CONTINUOUS INJECTION MOLDING

A carousel-like continuous co-injection molding system includes an arrangement of upper and lower inclined feed channels. Each of the feed channels has a valve therein positioned upstream of an inlet to an associated mold cavity. The valve is controllable so that adjustments may be made in real time to achieve or maintain delivery of molten polymeric material to the mold cavity at constant pressure.
