Mold forming machine

Abstract

A molding machine forms a mold by using a transferred molding flask and pattern plate, and includes: a filling frame; a squeeze head mechanism including a squeeze board movable into and out from the filling frame, and a plurality of squeeze feet passing through the squeeze board, being able to move up and down with respect to the squeeze board; a sand injection hopper including at least one sand injection port for injecting molding sand into a molding space defined by the molding flask, the filling frame, the squeeze head mechanism, and the pattern plate; and a sand injection nozzle provided in a component detachably attached to an opening of the side portion of the filling frame to enable the sand injection port and the molding space to communicate with each other.

1 . A molding machine forming a mold by using a transferred molding flask and pattern plate, the molding machine comprising:
 a filling frame provided with a lower opening connectable to an upper opening of the molding flask and a side portion opened;   a squeeze head mechanism including a squeeze board movable into and out from the filling frame, and a plurality of squeeze feet passing through the squeeze board, being able to move up and down with respect to the squeeze board;   a sand injection hopper including at least one sand injection port for injecting molding sand into a molding space defined by the molding flask, the filling frame, the squeeze head mechanism, and the pattern plate; and   a sand injection nozzle provided in a component detachably attached to an opening of the side portion of the filling frame to enable the sand injection port and the molding space to communicate with each other.   
     
     
         2 . A molding machine forming a mold by using a transferred molding flask and pattern plate, the molding machine comprising:
 a filling frame provided with a lower opening connectable to an upper opening of the molding flask;   an injection frame disposed above the filling frame, being provided with a lower opening connectable to an upper opening of the filling frame;   a squeeze head mechanism including a squeeze board movable into and out from the injection frame, and a plurality of squeeze feet passing through the squeeze board, being able to move up and down with respect to the squeeze board;   a sand injection hopper including at least one sand injection port for injecting molding sand into a molding space defined by the molding flask, the filling frame, the injection frame, the squeeze head mechanism, and the pattern plate; and   a sand injection nozzle provided in a side portion of the injection frame to enable the sand injection port and the molding space to communicate with each other.   
     
     
         3 . The molding machine according to  claim 1 , further comprising:
 a frame defining a part of the molding space and surrounding an outer periphery of the pattern plate to be slid up and down; and   a liner detachably formed in an inner portion of the frame.   
     
     
         4 . The molding machine according to  claim 3 , wherein the liner has an upper end surface and an inward surface, made of urethane rubber. 
     
     
         5 . The molding machine according to  claim 4 , wherein the urethane rubber has a heat-resistant temperature of 70 to 90° C. 
     
     
         6 . The molding machine according to  claim 4 , wherein the urethane rubber has a heat-resistant temperature of 110 to 130° C. 
     
     
         7 . The molding machine according to  claim 2 , further comprising:
 a frame defining a part of the molding space and surrounding an outer periphery of the pattern plate to be slid up and down; and   a liner detachably formed in an inner portion of the frame.   
     
     
         8 . The molding machine according to  claim 7 , wherein the liner has an upper end surface and an inward surface, made of urethane rubber. 
     
     
         9 . The molding machine according to  claim 8 , wherein the urethane rubber has a heat-resistant temperature of 70 to 90° C. 
     
     
         10 . The molding machine according to  claim 8 , wherein the urethane rubber has a heat-resistant temperature of 110 to 130° C.
