Problems solved by technology

If the casting temperature of the alloy liquid is too low, the mold temperature may be too low, insufficient pouring, cold shut; if the casting temperature is too high, the mold temperature is too high, and the cooling rate is too small, the surface grains may be coarse and the surface finish may be poor

Embodiment 1

[0047] Such as Figure 1-Figure 3 As shown, a blade casting mold includes an upper mold and a lower mold 1 corresponding to each other. The lower mold 1 and the upper mold are fitted with a first groove 8 for forming a three-dimensional twist on the lower edge of the blade; It includes a first upper mold assembly 2 and a second upper mold assembly 3 corresponding to each other. The abutting surfaces of the first upper mold assembly 2 and the second upper mold assembly 3 are attached to each other. The middle part of the part 2 and the second upper mold assembly 3 has a hollow space 4 for forming the main part of the blade, which is used to mold the thin-walled part of the main body of the blade, and the hollow space surface is three-dimensionally twisted and extended along the surface of the blade; The cover plate 10 is matched, and the second groove 17 used to form the upper edge of the blade is provided at the matching position of the cover plate 10 and the upper mold to mold...

Embodiment 2

[0064] Such as Figure 5 with Figure 7 As shown, one end of the first upper mold assembly 2 and the second upper mold assembly 3 is not attached, and a triangular mold 19 is set at the corners of the highest positions of the first upper mold assembly 2 and the second upper mold assembly 3 , The triangular mold 19 includes a first triangular mold assembly 20 and a second triangular mold assembly 21 corresponding to the front and rear, the first triangular mold assembly 20 and the second triangular mold assembly 21 are attached; the triangular mold is located at the gate It forms part of the runner, which facilitates the removal of the gate and mold removal after the low melting point alloy is solidified.

[0065] A runner 5 connected to the first groove 8 of the lower mold 1 is provided at the outer boundary of the triangular mold 19 near the third limiting plate 13; pouring is carried out from the runner 5, and the casting melt flows from the mold along the runner The first groo...

Embodiment 3

[0067] A method for forming blades includes the following steps:

[0068] Step 1: Clean the surfaces of the components of the blade casting mold, assemble the blade casting mold for use, and coat the inner surface of the blade casting mold with release agent;

[0069] Step 2: Weigh the casting materials according to the set requirements and clean the surface dust of the casting materials;

[0070] Step 3: Put the blade casting mold in the dryer to preheat, and use the temperature measurement module to monitor the temperature of the blade casting mold until the required temperature is set to stop preheating;

[0071] Step 4: Heat the casting material to melt to form a casting material solution, and use the temperature measurement module to monitor the temperature of the casting material solution until the required temperature is set to stop heating;

[0072] Step 5: Remove impurities on the surface of the casting material solution, pour the casting material solution into the blade castin...

Abstract

The invention discloses a blade casting die, application of the blade casting die and a blade forming method. The blade casting die comprises an upper die body and a lower die body which are correspondingly arranged. A first groove used for forming the lower edge portion of a blade is formed in the position, matched with the upper die body, of the lower die body. The upper die body comprises a first upper die assembly and a second upper die assembly which are arranged in a front-back corresponding manner. A gap used for forming a body part of the blade is formed between the first upper die assembly and the second upper die assembly. The upper portion of the upper die body is matched with a cover plate, and a second groove used for forming the upper edge portion of the blade is formed at the position, matched with the upper die body, of the cover plate. By means of the blade casting die, the application of the blade casting die and the blade forming method, due to the fact that the upper die body, the lower die body and the cover plate are matched in a blocking manner, the three-dimensional twisted blade can be manufactured. Due to the forming method, the surface of the die can be kept at a certain temperature, high-temperature molten liquid can be rapidly cooled at the same time after the space of the die is filled with the liquid, the blade forming quality is good, and surface defects are few.

Description

Technical field [0001] The invention belongs to the field of casting, and relates to a blade casting mold for products with blades, in particular to a blade casting mold and its application and a blade forming method. Background technique [0002] In the manufacturing process of products with blades, especially in the manufacturing process of enclosed impellers. The blades are often three-dimensionally twisted, and they are manufactured by direct machining, which is very difficult or even impossible to process. [0003] The existing blade manufacturing method is formed by setting the mold into the shape of the blade. However, when casting complex-shaped blades, especially three-dimensional twisted blades, it is difficult to set the mold directly into the blade shape. Because this is the difficulty of converting the blade casting into the difficulty of mold processing. Compared with blade casting, the mold processing process is more complicated and difficult to control. Blade mo...
