Resin Block Production Device, Resin Block Production Method, and Resin Block

Abstract

Resin pellets ( 7 ) supplied to a resin block forming space ( 150 ) are heated and melted by a heater unit ( 300 ) and the melted resin pellets ( 7 ) are cooled and solidified to form a resin layer. Since a lifting mechanism ( 230 ) of a lifting unit ( 200 ) lowers a bottom surface plate ( 215 ) whenever forming each of the resin layers, the resin layers formed by the resin block forming space ( 150 ) are sequentially laminated to form a large resin block.

1 . A resin block production method, comprising:
 supplying a resin material to a resin block forming space whose side surfaces are surrounded by a plurality of mold plates;   heating and melting the supplied resin material and cooling and solidifying the melted resin material repeatedly to form resin layers repeatedly in the resin block forming space;   lowering a bottom surface plate defining a bottom surface of the resin block forming space in which the resin layers are formed whenever forming each of resin layers so that each of the resin layers formed in the resin block forming space is sequentially laminated on the bottom surface plate or on each of the previously solidified resin layers; and   repeating the lamination of the resin layer to form a resin block in which the resin layers are laminated.   
     
     
         2 . The resin block production method according to  claim 1 , wherein the heating and melting the supplied resin material are performed from an upper surface of the resin block to be formed by a heating plate, the heating plate constituting an upper surface of the resin block forming space, the heating plate defining an upper surface of the resin block to be formed. 
     
     
         3 . The resin block production method according to  claim 1 , wherein the forming the resin block in the resin block forming space is performed under condition that the resin material in the resin block forming space is compressed at a predetermined pressure through the heating plate. 
     
     
         4 . The resin block production method according to  claim 1 , wherein the forming the resin block in the resin block forming space is performed under condition that the resin material in the resin block forming space is compressed at a predetermined pressure through the bottom surface plate. 
     
     
         5 . The resin block production method according to  claim 1 , wherein the resin material is a resin pellet and/or a crushed resin obtained by crushing any resin product. 
     
     
         6 . The resin block production method according to  claim 4 , wherein the resin material is a resin pellet and/or a crushed resin obtained by crushing any resin product. 
     
     
         7 . The resin block production method according to  claim 2 , wherein the forming the resin block in the resin block forming space is performed under condition that the resin material in the resin block forming space is compressed at a predetermined pressure through the bottom surface plate. 
     
     
         8 . The resin block production method according to  claim 2 , wherein the resin material is a resin pellet and/or a crushed resin obtained by crushing any resin product. 
     
     
         9 . The resin block production method according to  claim 3 , wherein the forming the resin block in the resin block forming space is performed under condition that the resin material in the resin block forming space is compressed at a predetermined pressure through the bottom surface plate. 
     
     
         10 . The resin block production method according to  claim 3 , wherein the resin material is a resin pellet and/or a crushed resin obtained by crushing any resin product.
