Provided are a die for injection forming, and an injection forming method. A first embedded block (3) and multiple second embedded blocks (4) form an upper die (41). A cylindrical heater (6) is disposed on a boundary part between the first embedded block (3) and the second embedded blocks (4) and is retained by the first embedded block (3) and the second embedded blocks (4), so that the heat transfer efficiency of the cylindrical heater (6) toward the second embedded blocks (4) is smaller than that of the cylindrical heater (6) toward first embedded block (3). Therefore, the heating and cooling performance of the die can be improved. The appearance of outer formed pieces will not be damaged even under a condition of continuous forming production with short forming intervals, and thus formed pieces with great states can be provided. |
