MOLDING DEVICE, MOLD, AND MOLDING MANUFACTURING METHOD

To provide a molding device which can easily and efficiently obtain a molding having good quality by injection molding.SOLUTION: A molding device includes: a mold 10 for injection molding having a communication hole 140 that communicates the outside with a cavity 100; an injection device 70 that supplies a molding material in a molten state into the cavity 100; microwave irradiation means 30; and transfer means 20 for microwave transfer whose one end is mounted in the microwave irradiation means 30 and other end is mounted in the mold 10 so as to irradiate the inside of the cavity 100 through the communication hole 140 with the microwaves, in which the mold 10 is formed with a flow channel 110 for guiding a molding material supplied from the injection device 70 into the cavity 100 together with the cavity 100, and the inside of the cavity 100 is irradiated with the microwaves so that intensity of the microwaves becomes high in the opening 130 and its vicinity to which the molding material is injected into the cavity 100 from the flow channel 110.SELECTED DRAWING: Figure 1 【課題】射出成形により、品質のよい製品を容易に、かつ効率的に得ることができる成形装置等を提供する。【解決手段】外部とキャビティ１００とを連通する連通孔１４０を有している射出成形用の金型１０と、成形材料を溶融状態でキャビティ１００内に供給する射出装置７０と、マイクロ波照射手段３０と、マイクロ波照射手段３０に一端が、連通孔１４０を介してキャビティ１００内にマイクロ波を照射するべく他端が金型１０に取り付けられたマイクロ波伝送用の伝送手段２０と、を備え、金型１０には、射出装置７０から供給される成形材料をキャビティ１００内に導くための流路１１０がキャビティ１００とともに形成され、流路１１０からキャビティ１００内に成形材料が射出される開口部１３０およびその近傍においてマイクロ波の強度が強くなるよう、キャビティ１００内にマイクロ波が照射されるようにした。【選択図】図１
