PROBLEM TO BE SOLVED: To reduce difference between characteristics of molded items by opening a pot in a substantially elliptical shape on the surface in which a first mold and second mold are opposite to each other, and allowing respective transportation passages connected to each cavity to be joined one another to the pot in a state of non-intersection. SOLUTION: A pot 5 is opened into a substantially elliptical shape on the surface in which a first mold 1 and second mold 2 are opposite to each other. When a plunger 6 is removed, the opening part is made to be connected from the upper surface of the first mold to its lower surface. Around the pot 5, respective transportation passage 4 joined to each cavity 3 are arrayed in the long axial direction of the substantially elliptical shape opening. Then, each transportation passage 4 is connected respectively to the pot 5 in a state of non- intersection. Further, each cavity 3 is arrayed in the long axial direction of the elliptical opening part. In each transportation passage 4, each one cavity is joined so as to render each cavity 3 and each transportation passage 4 substantially the same in length. |
