PROBLEM TO BE SOLVED: To reduce the volume of material to be used, facilitate molding and conduct complete molding one by one into two to four pieces fitted onto a movable plate surface by conducting direct injection into a piece mold positioned inside the plate surface from an injection nozzle. SOLUTION: The material injected from a gate at a lower part is filled in a product cavity, and is molded by cooling and heating. After the completion of opening a mold, a protruding pin fixing plate on the right is moved to the left to push out a product. Key grooves on the right and left of a piece mold A serves as a stopper. This is used to mold a complicated product with core. As one example, on both sides of the piece mold, two core cylinders 15 are connected to the core in the piece molds. After the completion of drawing-out, the protruding pin is operated for mold release. A cylinder stopper ring 23 is also provided, and a is installed in the square piece mold for the piece. The outer periphery of a nozzle B is made a magnetic paste seal surface. |
