Title (EN) DEVICE AND METHOD FOR PRODUCTION OF A PLATE-LIKE FOAMED MOULDED PLASTIC PRODUCT
(FR) DISPOSITIF ET PROCÉDÉ DE PRODUCTION D'UN PRODUIT EN PLASTIQUE MOULÉ EN MOUSSE EN FORME DE PLAQUE
Abstract:
(EN) The invention creates a device (1; 101) for production of an at least substantially plate-like foamed moulded plastic product (75; 79; 203). The device comprises a frame (2), a mould, first supply means (71) for supplying plastic material to be foamed to the mould cavity (15) of the mould, and second supply means for supplying steam to the mould cavity (15) filled with the plastic material. A first mould body (8; 108) of the mould comprises a box shaped first mould wall (11; 111), a second mould wall (12; 112) on the inside of the box form of the first mould wall (11; 111). The second mould wall (12; 112) adjoins the first mould wall (11;111). Via the second mould wall (12; 112), steam may be supplied to the mould cavity (15). The device (1; 101) furthermore comprises a sealing body (16) on the inside of the first mould wall (11; 111) on the side of the second mould wall (12; 112) facing away from the mould cavity (15). The sealing body (16) adjoins the first mould wall (11; 111), and first sealing means (18, 19) for sealing the seam between the first mould wall (11; 111) and the sealing body (16). A first steam cavity (20) is formed between the first mould wall (11; 111), the second mould wall (12;112) and the sealing body (16). Second supply means are configured for supplying steam from the first steam cavity via the second mould wall (12; 112) to the mould cavity (15). The device (1; 101) comprises furthermore second movement means for jointly moving the second mould wall (12; 112) and the sealing body (16) relative to the first mould wall (11; 111). The invention furthermore creates a number of methods.
(FR) L'invention concerne un dispositif (1 ; 101) de production d'un produit en plastique moulé en mousse au moins sensiblement en forme de plaque (75 ; 79 ; 203). Le dispositif comprend un cadre (2), un moule, des premiers moyens d'alimentation (71) permettant de fournir du matériau plastique à mousser dans la cavité de moule (15) du moule et des seconds moyens d'alimentation, permettant de fournir de la vapeur à la cavité de moule (15) garnie du matériau plastique. Un premier corps de moule (8 ; 108) du moule comprend une première paroi de moule (11 ; 111) en forme de boîte, une seconde paroi de moule (12 ; 112) sur l'intérieur de la forme de boîte de la première paroi de moule (11 ; 111). La seconde paroi de moule (12 ; 112) est adjacente à la première paroi de moule (11 ; 111). Par l'intermédiaire de la seconde paroi de moule (12 ; 112), de la vapeur peut être fournie à la cavité de moule (15). Le dispositif (1 ; 101) comprend en outre un corps d'étanchéité (16) à l'intérieur de la première paroi de moule (11 ; 111) sur le côté de la seconde paroi de moule (12 ; 112), opposée à la cavité de moule (15). Le corps d'étanchéité (16) est contigu à la première paroi de moule (11 ; 111) et à des premiers moyens d'étanchéité (18, 19), destinés à sceller la jonction entre la première paroi de moule (11 ; 111) et le corps d'étanchéité (16). Une première cavité de vapeur (20) est formée entre la première paroi de moule (11 ; 111), la seconde paroi de moule (12 ; 112) et le corps d'étanchéité (16). Des seconds moyens d'alimentation sont conçus pour fournir de la vapeur à partir de la première cavité de vapeur, par l'intermédiaire de la seconde paroi de moule (12 ; 112), jusqu'à la cavité de moule (15). Le dispositif (1 ; 101) comprend en outre des seconds moyens de déplacement, permettant de déplacer conjointement la seconde paroi de moule (12 ; 112) et le corps d'étanchéité (16) par rapport à la première paroi de moule (11 ; 111). L'invention concerne en outre un certain nombre de procédés.
