<p>#CMT# #/CMT# The mold (101) has a casting block (104) whose internal face includes a mobile part or matrix (103) fixed to a mobile backing platen and displaced in translation by the platen between closing and opening positions. Upper and lower faces of an intermediate casting block (113) respectively have a molding shape i.e. punch (117), and a molding shape i.e. matrix (116) such that one of punches (105, 117) and one of matrices (110, 116) form a trace for molding a part when the mold is closed. Opening and closing units open and close different stages of the mold during displacement of the platen. #CMT#USE : #/CMT# Mold for molding of plastic or thermohardened thermoplastic parts by compression, resin transfer, injection or compression injection (all claimed). Uses include but are not limited to an automobile field for molding door panel, side panel, body panel, lift gate, roof panel, bonnet, sideview mirror, seat support, seat backrest, or luggage-covering shelf, a railway sector, an aeronautical or aerospace construction, a naval construction, an electrical industry, a sanitary field, a furniture field, a sport field, a leisure field, or to a building field for molding protection and insulation panel, shingle, plane or corrugated translucent plate or bathroom element such as bathtub, wash basin, shower or sink. #CMT#ADVANTAGE : #/CMT# The mold ensures molding of two identical parts to the part or simultaneous molding of the part with another part by using the production press without increasing power required for the press, and converses mechanical characteristics. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an enlarged perspective view of a mold, with stages, including a single intermediate casting block for compression molding in an opening position between the intermediate casting block and a punch, with a person being represented. 101 : Mold 103 : Mobile part or matrix 104 : Casting block 105, 117 : Punches 110, 116 : Matrices 113 : Intermediate casting block.</p> |
