| 摘要 |
<p>The invention relates to a method and a device for the production of heavy-duty plastic molded parts with a hollow profile, particularly separation cans or containment shells for pumps, in a mold tool (1), having at least one first and one second tool part (2, 3), wherein at least one tool part (2, 3) is moved relative to the other part (2, 3) to open and close the mold tool (1). A longitudinal cavity (10) is constructed in the first tool part (2), a longitudinal mold core (4) of the second tool part (3) being inserted into said cavity coaxially, forming a cavity (15) which corresponds to the hollow profile. As part of this process, initially a reinforcement means (20) made of continuous fibers is applied to the mold core (4). Finally, the mold tool (1) carries out an opening or closing movement (A, B), during which a plastics molding material is continuously injected into the cavity through an injection opening or openings (8) which extend(s) radially along the periphery of said cavity (15), the material completely enclosing the reinforcement means (20).</p> |
