Injection molding method and apparatus for underlaying a top materials with plastic

An injection molding apparatus for underlaying a flexible top material with plastic to be injected inside a cavity which is formed between a female mold core plate and a mold core, comprising:

• a dipping edge slider being movable with respect to the female mold core plate, the slider including a first dipping edge;
• and
• a second dipping edge being formed on a separation slider, the first dipping edge and the second dipping edge forming a dipping edge gap that adjoins the cavity into which gap the top material extends.

A method for producing a composite material such that a flexible top material is underlaid with plastic in a cavity, which is formed between a female mold plate and a mold core, such that the top material extends into a dipping edge gap adjoining the cavity, the gap being bounded by a dipping edge on the female mold side and by a dipping edge on the core mold side, wherein a separation slider, on which the dipping edge on the mold core side is formed, together with a dipping edge slider, on which is formed the dipping edge on the female mold side, are moved, after the top material has been underlaid, in such a way that another plastic component can be injected into a supplementary cavity.

A method for producing a composite material such that a flexible top material is underlaid with plastic in a cavity, which is formed between a female mold plate and a mold core, such that the top material extends into a dipping edge gap adjoining the cavity, the gap being bounded by a dipping edge on the female mold side and a dipping edge on the core mold side, wherein a separation slider, on which the dipping edge on the mold core side is formed and which has a cutting edge, together with a dipping edge slider, on which the dipping edge on the female mold side is formed, after the top material has been underlaid, are moved in such a way that the top material is cut off at the end of the cavity.

A method for underlaying a flexible top material with plastic inside a cavity which is formed between a female mold core plate and a mold core, comprising:

• providing a dipping edge slider that is movable with respect to the female mold core plate, the slider including a first dipping edge;
• and
• forming a second dipping edge on a separation slider, the first dipping edge and the second dipping edge forming a dipping edge gap that adjoins the cavity into which gap the top material extends.

An injection molding apparatus for underlaying a flexible top material with plastic to be injected inside a cavity, which is formed between a female mold core plate and a mold core, with a dipping edge on the female mold side and another dipping edge on the mold core side, which bound a dipping edge gap that adjoins the cavity, into which gap the top material situated in the cavity extends, the dipping edge on the female mold side being formed on a dipping edge slider that is movably mounted on the female mold plate, the dipping edge slider having a stop which interacts with a counter-stop formed on the female mold plate to bound the path of motion, the apparatus also including at least one element for adjusting the gap size, the at least one element being situated between the stop of the dipping edge slider and the counter-stop of the female mold plate.

An injection molding apparatus for underlaying a flexible top material with plastic to be injected inside a cavity, which is formed between a female mold core plate and a mold core, with a dipping edge on the female mold side and another dipping edge on the mold core side, which bound a dipping edge gap that adjoins the cavity, into which gap the top material situated in the cavity extends, the dipping edge on the female mold side being formed on a dipping edge slider that is movably mounted on the female mold plate, the dipping edge at the mold core side being formed on a separation slider which is movably guided on the mold core plate.
