Water absorbing plate of pressing mold

Abstract

The invention discloses a water absorbing plate of a pressing mold. The water absorbing plate comprises a water absorption groove, water absorption holes and water storage grooves, wherein the water absorption holes, the water storage grooves and the water absorption groove communicate with each other, the top and the bottom of the water absorption plate are further provided with an inner arc surface and an outer arc surface respectively, the circumferential ring of the inner arc surface is provided with the water absorption groove, and after being pressed by a press machine, the water absorption groove is matched with a green body; the water absorption holes are arranged on the arc surfaces, and communicate the inner arc surface and the outer arc surface, the outer end of the outer arc surface is a cavity part, the water storage grooves are arranged on the outer sides of the water absorption holes, and inclined grooves are formed between the water storage grooves and the cavity; and the arc top position of the outer arc surface is higher than the positions of the water storage grooves, each water storage groove is connected with a water nozzle, and water in the water absorption groove is sucked into the inclined grooves by the water absorption holes, then flows into the water storage groove, and is discharged through the water nozzle. According to the water absorbing plate, the water absorbing effect is good, water can be better sucked away from the green body, the density of all parts of the green body can be ensured to be uniform and basically consistent, and the green body can be prevented from cracking again during sintering.

Description

technical field [0001] The invention relates to the technical field of a compact formed by pressing. More specifically, the present invention relates to a water-absorbing sheet for pressing a mold. Background technique [0002] In the existing water-absorbing board, during use, the phenomenon that the water is not sucked dry on the outer arc of the green body often occurs, or the water drops directly on the outer arc of the green body, and fresh water drops appear to cause the green body to crack. [0003] Such as figure 1 The water-absorbing board shown has little water absorption, especially there is no water-absorbing hole on the curved surface of the water-absorbing board and the green body, and the green body often cannot absorb water; the volume of the water storage chamber A is small, because its water storage chamber A Directly on the upper end of the water suction hole, it is difficult to play the role of water storage, and the water that is not vacuumed is easy t...

Problems solved by technology

[0002] In the existing water-absorbing board, during use, the water on the outer arc of the green body is often not absorbed or the water is directly dripped on the outer arc of the green body, and fresh water drops appear to cause the green body to crack

[0003] like figure 1 The water-absorbing board shown has little water absorption, especially there is no water-absorbing hole on the curved surface of the water-absorbing board and the green body, and the green body often cannot absorb water; the volume of the water storage chamber A is small, because its water storage chamber A Directly on the upper end of the water suction hole, it is difficult to play the role of water storage, and the water that is not vacuumed is easy to flow back and directly flow on the outer arc of the green body, which is easy to cause the green body to crack
