Title:
ダイカストマシンの射出装置および鋳造方法
Document Type and Number:
Japanese Patent JP7127527
Kind Code:
B2
Abstract:
Inflow of outside air into a suctioned sleeve is prevented, problems with molten metal are suppressed, and stable suction within the sleeve is realized. The injection device 1 of a die casting machine100 is configured to permit suction of a suction recess 120, which is partitioned by a tip 20 of a plunger 12, and a space 75 ahead of the front end of the tip 20. The inside of a sleeve 11 can be suctioned through penetrating portions 14, 15 that each penetrate the sleeve 11 from inside to outside at a prescribed first location C1 of the sleeve 11 in the advancing/retreating direction D1 of theplunger 12 and at a second location C2 set apart rearward from the first location C1. The opening area of the penetrating portion 15 at the first location C1 is greater than the opening area of the penetrating portion 14 at the second location C2.
