Method and Apparatus for Manufacturing Vehicle Parts

Abstract

The invention relates to a method for manufacturing at least partly plastic vehicle parts in a mold with at least one mold cavity, comprising the steps of at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by means of at least one movable wall part of the at least one mold cavity; introducing plastic into the at least one mold cavity; upon complete closure of the mold and/or movement of the at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in the second position having a different volume than in the first position; all this in such a manner that by bringing the at least one mold cavity from the first into the second position, the plastic fills the respective mold cavity completely.

1 . A vehicle part manufactured in a mold with at least one mold cavity, the vehicle part comprising a form that is shaped by:
 at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by moving at least one wall part of the at least one mold cavity;   introducing plastic into the at least one mold cavity;   upon complete closure of the mold and/or movement of the at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in the second position having a different volume than in the first position;   wherein by bringing the at least one mold cavity from the first in the second position, the plastic fills the respective mold cavity completely.   
     
     
         2 . A vehicle part according to  claim 1 , wherein the part is provided on at least a portion of an outer surface thereof with a covering, which is fixedly connected to the part. 
     
     
         3 . A vehicle part according to  claim 2 , wherein the covering comprises textile manufactured from natural and/or synthetic materials. 
     
     
         4 . A vehicle part according to  claim 1 , which part is substantially thin-walled and of a substantially two-dimensional configuration. 
     
     
         5 . A textile for use for the manufacture of a part according to  claim 1 , wherein either a partly plastic backing is provided or wholly or partly plastic threads or threads provided with a finishing layer are provided as warp and/or weft. 
     
     
         6 . A mold for the manufacture of a part according to  claim 1 . 
     
     
         7 . A mold according to  claim 6 , provided with at least one mold cavity with a movable wall part which is controllably movable for compressing plastic in the mold cavity when the mold is closed, thereby generating adiabatic heat development in the plastic. 
     
     
         8 . A plastic part manufactured in a mold with at least one mold cavity, the plastic part comprising a form that is shaped by:
 at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by means of at least one movable wall part of the at least one mold cavity;   introducing plastic into the at least one mold cavity;   upon complete closure of the mold and/or movement of said at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in the second position having a different volume than in the first position;   wherein by bringing the at least one mold cavity from the first in the second position, the plastic fills the respective mold cavity completely.   
     
     
         9 . A plastic part according to  claim 8 , wherein the part is provided on at least a portion of an outer surface thereof with a covering which is fixedly connected to the part. 
     
     
         10 . A plastic part according to  claim 9 , wherein the covering comprises textile manufactured from natural and/or synthetic materials. 
     
     
         11 . A plastic part according to  claim 8 , which part is substantially thin-walled and of a substantially two-dimensional configuration. 
     
     
         12 . A method for manufacturing at least partly plastic parts in a mold with at least one mold cavity, comprising:
 at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by means of at least one movable wall part of the at least one mold cavity;   introducing plastic into the at least one mold cavity;   upon complete closure of the mold and/or movement of said at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in the second position having a different volume than in the first position;   wherein by bringing the at least one mold cavity from the first in the second position, the plastic fills the respective mold cavity completely.   
     
     
         13 . A method for manufacturing at least partly plastic parts in a mold with at least one mold cavity, comprising:
 at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by means of at least one movable wall part of the at least one mold cavity;   introducing plastic into the at least one mold cavity, pushing the at least one movable wall part away from the first position;   upon complete closure of the mold and/or movement of said at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in the second position having a different volume than in the first position;   wherein by bringing the at least one mold cavity from the first in the second position, the plastic fills the respective mold cavity completely.
