Description

Technical Field

[0001] The utility model belongs to the technical field of hot isostatic pressing, in particular to a hot isostatic pressing forming die. Background Art

[0002] Hot isostatic pressing molds are key tools used in the hot isostatic pressing process. They are usually made of high-strength, high-temperature resistant materials such as metals or ceramics. In the HIP process, the mold is used to carry and seal the product to be processed. Subsequently, high temperature and high pressure are applied simultaneously in a closed container to achieve sintering and densification of the product.

[0003] For example, a Chinese patent with publication number CN219902573U discloses a hot isostatic pressing mold for a mouth template blank, including a base plate, an upper mold, a lower mold and a ejection mechanism, the lower mold is fixed to the top of the base plate by four support rods, the upper mold is inserted into the top of the lower mold, and the ejection mechanism is arranged on the top of the base plate, the ejection mechanism includes a pressing assembly, three ejection blocks and three lifting assemblies, the pressing assembly is arranged on the top of the base plate, a U-shaped platform is fixed on the top of the base plate, three lifting assemblies are arranged on the U-shaped platform, and each ejection block is fixed on a lifting assembly. The utility model involves a hot isostatic pressing mold for a mouth template blank, which can form three cup mouth templates at a time instead of one at a time, which not only improves the hot isostatic pressing efficiency of the cup mouth template, but also helps to expand production and increase corporate profits.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used, such as: during the operation of the device, the operator is required to drive the demoulding action of the mold by stepping on the pedal. During the demoulding process, the product may adhere closely to the inner wall of the mold, forming too strong adhesion, so that the mold may not be successfully demoulded completely by human power through pedal driving alone. At the same time, the above device adopts a simple fixing method in which four plug rods are respectively inserted into four sockets, which may cause air leakage from the joint between the upper mold and the lower mold due to insufficient sealing, thereby affecting the molding quality of the product and causing defects such as uneven product surface, internal bubbles or shrinkage holes. In view of this, we propose a hot isostatic pressing mold. Utility Model Content
