Embodiment Construction

[0026] refer to figure 1 , which illustrates a core part 2 of an injection molding mold according to the present invention. The injection molding mold also includes a cavity part (not shown) that is complementary to the core part. During product molding, the cavity part is lowered onto the core part and plastic material is injected between these two parts in order to produce the desired product.

[0027] exist figure 1 In the example shown, the core part is subdivided into a left side 4 and a right side 6 , which are symmetrical about the central axis 8 of the core part 2 . Each side defines a molding cavity 12 which is generally banana-shaped. Each molding cavity 12 is used to produce a duct cover for the interior of the vehicle.

[0028] The core part 2 comprises four regions 14 each defining a mold for shaping the loudspeaker grill inside the injection molded product. An injection molded product discharge device is provided under and inside the core part 2 .

Abstract

An injection mould product ejection apparatus comprising: an ejection element; and a displacing member for displacing the ejection element between a retracted moulding position and a first extended ejection position; wherein, the ejection element is an ejection assembly and comprises: a) an inner ejection sub-assembly, and b) an outer ejection bush surrounding the inner ejection sub-assembly, said displacing member comprises: a collective displacing member, for displacing the whole ejection assembly from the retracted moulding position to an intermediate ejection position, and a sub-assembly displacing member, for converting the ejection assembly from the intermediate ejection position to the first extended ejection position by extending the sub-assembly relative to the outer ejection bush.

Description

technical field [0001] The invention relates to an injection molded product ejection device comprising an ejection element and a displacement member for moving the ejection element between a retracted molding position and a first extended ejection position, and to a A method of ejecting an injection molded product. Background technique [0002] Such a device and method are known from document JP2001239559. This document discloses an injection molding mold for producing loudspeaker diaphragms. The injection molding mold includes an ejection sleeve having a wider ejection surface than that provided by the ejection pin. When molding is complete, the loudspeaker diaphragm can be ejected from the injection molding mold without risk of diaphragm rupture due to the wider ejection surface. [0003] This known ejection system is an improvement over ejection systems using simple ejection pins. However, it is only suitable for relatively simple injection molded products, such as di...
