<p>A mold and an injection process for obtaining a bicycle frame made of recyclable polymer, more specifically, it is related to a mold (1) and an injection process (PO) for obtaining a bicycle frame from which a single-piece and polymeric bicycle frame (QB) is obtained with resistant and flexible mechanical features; said mold is made up of two complementary parts, namely: one stationary part (2) and one movable part (3) whereof sliding columns (3A) are provided with guiding lower portions (2A) provided in the stationery part (2); both the stationary part (2) and movable part (3) are provided with base plates (2b) and (3b) whereof respective bearing cavities plates plates are assembled (2c) and (3c) to jointly make up a structural channel (CE) so as to receive the thermal injected polymer (T1) and to obtain a bicycle frame (QB) subsequently; the cavity bearing plate (3c) in the movable part (3) is provided with a longitudinal bed (3d) whereof the main central drawer (GP) is assembled in and is further provided with side beds (3e) whereof secondary drawers (GS) are assembled in. Said longitudinal bed (3d) is provided with peripheral tracks (3f) to allow the main drawer (GP) to slide therethrough; further, said bed is provided with drawing pins (3g) positioned in an angle so as to allow the main drawer (GP) to horizontally move on (MH). Side beds (3e) are also provided with drawing pins (3g') for the secondary drawers (GS).</p> |
