[0004] To achieve the above objectives, this utility model provides a combined mold for a powder metallurgy blade rotor, including a mold body and a die located inside the mold body and detachably connected to the mold body. The die is equipped with a die insert, and also includes a die upper cover detachably connected to the die and a die lower cover detachably connected to the mold body.

[0005] Furthermore, the molding die includes a main body and an intermediate part, which are integrally formed. The mold has a mounting groove for installing the mold insert, and the mounting groove runs vertically through the middle part and the main body.

[0006] Furthermore, the molding insert includes a first part and a second part, the first part cooperating with the middle part, and the second part cooperating with the main body part.

[0007] Furthermore, the upper cover of the mold is located on the outer periphery of the middle part, and the second part and the main body part are located on the lower side of the upper cover of the mold; The mold cover is fixedly connected to the main body by screws.

[0008] Furthermore, the upper surface of the mold cover is flush with the upper surface of the middle part and the upper surface of the mold body.

[0009] Furthermore, the lower cover of the mold is fixedly connected to the mold body by screws.

[0010] The beneficial effects of this utility model are as follows: This invention improves the stability, maintenance convenience, and product precision of the mold through an integrated molding structure, segmented insert design, and fully detachable connection method. It is especially suitable for the production of high-precision, complex blade rotors and has a wider range of application prospects and economic value. Attached Figure Description

[0012] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0014] Combination Figures 1-5 As shown, this utility model provides a combined mold for a powder metallurgy blade rotor, including a mold body and a pressing mold located inside the mold body and detachably connected to the mold body. The pressing mold is equipped with pressing mold inserts, and also includes a pressing mold upper cover detachably connected to the pressing mold and a pressing mold lower cover detachably connected to the mold body. According to one embodiment of this utility model, the pressing mold 2 includes a main body portion 21 and an intermediate portion 22, which are integrally formed.

[0015] The mold 2 has a mounting groove 23 for mounting the mold insert 3. The mounting groove 23 extends vertically through the middle part 22 and the main body part 21. The mold insert 3 includes a first part 31 and a second part 32. The first part 31 mates with the middle part 22, and the second part 32 mates with the main body part 21. The mold top cover 4 is located on the outer periphery of the middle part 22. The second part 3 and the main body part 21 are located on the lower side of the mold top cover 4. The mold top cover 4 is fixedly connected to the main body part 21 by screws. The upper surface of the mold top cover 4 is flush with the upper surface of the middle part 22 and the upper surface of the mold body 1. The mold bottom cover 5 is fixedly connected to the mold body 1 by screws.

[0016] The main body and middle part of the mold of this utility model adopt an integral molding design, which can reduce the risk of deformation and improve the overall strength of the mold during high pressure pressing. The mold insert cooperates with the mold through a through-type mounting groove, and is divided into two parts that are adapted to the middle part and the main body of the mold respectively, so that the force is more evenly distributed, reducing local wear and extending service life.

[0017] Furthermore, in this invention, both the upper and lower covers of the mold are detachably connected to other components via screws, and the mold and die body are also detachable, making replacement more convenient and reducing maintenance costs and downtime. For example, when the mold insert is partially worn, only the insert needs to be replaced, without replacing the entire mold.

[0018] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
