Problems solved by technology

[0003] The existing wet cold isostatic pressing molding technology mostly uses polyurethane or rubber as the mold. The mold itself has a relatively large thickness and has no support frame, which is likely to cause uneven pressure. Therefore, the size of the green body is difficult to control and difficult to One-time molding of near-net size will increase the workload of subsequent green body processing; moreover, most of the products made are round rods or hollow

Example Embodiment

[0021] Specific embodiments are provided below and the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0022] like figure 1 As shown, the wet cold isostatic pressing mold of the present invention is a composite mold made of various materials, including a mold body and a mold cover plate 3, wherein the mold body is composed of a soft inner sleeve 1 and a control mold 2 , a number of diversion holes 5 are distributed on the control-type master mold 2 .

[0023] The soft inner sleeve 1 is made of high-toughness, high-pressure-resistant organic material, has a certain thickness, and is mainly used to control the flow of powder. Specifically, the soft inner sleeve 1 can be made of rubber or its derivative products with a thickness of 0.1-5.0mm and a pressure resistance of 220Mpa≥P≥60Mpa, such as fluororubber, silicone rubber or epichlorohydrin rubber. The soft inner slee...

Abstract

The invention provides a wet-type cold isostatic pressing mold, which includes a mold body and a mold cover plate. During operation, a sealing device is used to seal and fix the mold cover plate on the mold body. It is characterized in that the mold body is composed of a soft inner sleeve and a control The outer part of the soft inner sleeve is the control mold, the soft inner sleeve is attached to the inner wall of the control mold, and there are several diversion holes distributed on the control mold. The holes conduct pressure uniformly to the soft inner sleeve. The wet cold isostatic pressing mold of the present invention has a reasonable structure and is easy to operate, and can withstand the wet cold isostatic pressing forming with a production pressure of 60‑220Mpa, protects the materials inside the mold from erosion, and most importantly can make the cold isostatic pressing The molding technology achieves one-time molding of near-net size, which ensures the accuracy of one-time molding of the green body to the greatest extent, improves production efficiency and reduces manufacturing costs.

Description

technical field [0001] The invention relates to a wet-type cold isostatic pressing die, which belongs to the technical field of pressing dies for ceramics and powder metallurgy. Background technique [0002] Isostatic pressing technology is a technology that uses the products in a closed high-pressure container to form under the state of uniform ultra-high pressure in all directions. It is mainly used in powder forming of powder metallurgy, and has a wide range of applications in ceramic casting and other fields. According to the temperature during forming and consolidation, isostatic pressing technology is divided into three different types: cold isostatic pressing, warm isostatic pressing, and hot isostatic pressing. Cold isostatic pressing is to use liquid as the pressure medium at room temperature to form powder materials and provide green bodies for further sintering, forging or hot isostatic pressing processes. Cold isostatic pressing is divided into two types: wet ty...
