摘要： PURPOSE:To prevent the generation of a crack in a molding having an intricate shape by forming a lower punch of a die set for powder molding of plural constituting bodies and mounting an elastic body between the constituting body positioned on the outside thereof and a lower punch plate thereunder. CONSTITUTION:The 1st, 2nd, 3rd lower punch constituting bodies 11a, 11b, 11c attached at the bottom end respectively to lower punch plates 15, 16, 17 are laminated and fitted to form a lower punch 11. An elastic material 31 of urethane rubber, etc. is held via an adapter 32 between the body 11c on the outside and the plate 17. A gap (e) is preliminarily formed between the base 38 at the boss of the adapter 32 and the top surface 39 of the lower punch plate 17. Powder is packed in the space enclosed by the top plate of the lower punch 11 and the hole of the die in this state and the upper punch is lowered to compress to mold a molding W. When the upper punch is risen, the constituting body 11c is slightly moved by as much as the gap (e) to the upper punch side and therefore the generation of a crack in the molding W due to the popping up phenomenon is prevented.

摘要： PURPOSE:To obtain pressed powder without beads and without change in a middle tray which holds a cosmetic material by working the middle tray simultaneously by utilizing the stress at which the solidified cosmetic material is packed in the middle tray. CONSTITUTION:A sheet material 10 which deforms plastically is placed on a die 5' and a punch 4' provided with a guide hole 2' is set from above. A powdered cosmetic material 6 is packed in the hole 2' and the material 6 is compressed with a punch 7'. At this same instant, the material 10 is formed to the prescribed shape punched in the die 5'. The pressed powder 13 holding the material 6 in a middle tray 1' is obtained. The pressed powder 13 is thus obtained without beads and without change in the middle tray.

摘要： PURPOSE:To produce a pulverous material having high quality and excellent dimensional accuracy by both pressing with an upper die and a lower die in the stage of compression molding of powder raw materials in dies by compressing said raw materials while moving a metallic flask contg. the powder raw materials downward only by the frictional force between the raw materials and the metallic flask. CONSTITUTION:Supporting devices 5 for a metallic flask 4 having a molding hole 6 is provided on a stationary base 1, and cylinders 7 are connected via a change-over valve 27 to a hydraulic source 11. After a lower die 3 is set in the hole 6, powder raw materials (a) are charged into the hole 6, and an upper die 19 is moved downward to advance the bottom end part thereof into the hole 6. Since the flask 4 is supported by the devices 5 on the base 1, the flask does not descend and after the air is thoroughly removed from the raw materials by low pressure compression, the valve 27 is changed over by the transmitting bodies 20 actuated by the descending of a plate 18 for moving the die upward and downward, so that the descending force of the plate 18 is released from the flask 4. The flask 4 is moved downward only by the frictional force with the raw material powder (a) and is compressed by both from the upper die 19 and the lower die 13, whereby a molded product having high quality and excellent dimensional accuracy is obtained.
