Description

Technical Field

[0001] This utility model relates to the field of impeller manufacturing and processing technology, specifically to an integrated molding die for a gradient nanocomposite material impeller. Background Technology

[0002] An impeller can refer to a wheel disk equipped with moving blades, which is a component of the rotor of an impulse steam turbine, or it can refer to the wheel disk and the rotating blades mounted on it. The impeller is the core component of a fan, responsible for converting mechanical energy into the kinetic energy of airflow.

[0003] In modern industrial fields such as aerospace and energy, impellers are key components with increasingly higher performance requirements. Gradient nanocomposite materials are considered ideal materials for manufacturing high-performance impellers due to their unique microstructure and excellent properties. However, due to the structural characteristics of impellers, most current manufacturing methods require different parts of the impeller to be molded separately and then assembled. This not only increases the manufacturing process and cost, but also makes it difficult to guarantee the connection strength of the assembled parts, which becomes a weak link in the overall performance of the impeller.

[0004] The unique properties of gradient nanocomposites make the process parameters extremely demanding during molding. Traditional molds and molding processes make it difficult to precisely control the flow and solidification of materials within the mold, which can easily lead to defects inside the impeller, such as pores and cracks, seriously affecting the quality and performance of the impeller. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an integral molding mold for gradient nanocomposite impeller, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an integral molding mold for a gradient nanocomposite impeller, comprising: a lower mold, a plurality of insertion holes evenly provided at the top of the lower mold, a side mold inserted into the top of the insertion holes, a positioning pin fixedly connected to the bottom of the side mold, the positioning pin being inserted into the inside of the insertion holes, and a heating coil fixedly connected to the middle of the lower mold.

[0008] It also includes: an upper mold, an outer ring fixedly connected to the bottom edge of the upper mold, a vent fixedly connected to one end of the top of the upper mold, an inner ring fixedly connected to the middle of the bottom of the upper mold, a temperature sensor fixedly connected to one side of the bottom of the inner ring, and a pressure sensor fixedly connected to the other side of the bottom of the inner ring.

[0009] Furthermore, positioning grooves are provided on both sides of the insertion hole, and positioning protrusions are fixedly connected to both sides of the positioning pin, with the positioning protrusions and positioning grooves cooperating and connecting with each other.

[0010] Furthermore, a limiting groove is provided at the edge of the bottom end of the lower mold, and a limiting ring is fixedly connected to the bottom end of the outer ring, with the limiting ring snapped into the inside of the limiting groove.

[0011] Furthermore, injection holes are provided on both sides of the top of the upper mold, and injection ports are fixedly connected to the top of the injection holes.

[0012] Furthermore, a through hole is provided in the middle of the inner ring, and a fixing bolt is fixedly connected to the middle of the top of the lower mold. The fixing bolt is inserted into the inside of the through hole, and a fixing nut is threaded onto the other end of the fixing bolt.

[0013] Furthermore, the fixing bolts and fixing nuts cooperate to fix the lower mold and the upper mold together, and an impeller is provided between the lower mold and the upper mold.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. By setting up a lower mold, side mold and upper mold, the lower mold, side mold and upper mold are spliced ​​together to form the shape of an impeller in the cavity inside the mold. Then, the nanocomposite material is injected from the injection port and solidified inside the mold to form an impeller. This enables the one-piece molding of the gradient nanocomposite impeller, avoiding many problems caused by assembly after split molding, and improving the overall performance and reliability of the impeller.

[0016] 2. By setting the side mold, the molded impeller and the side mold are separated from the lower mold together during demolding. Then the side mold is pulled out from the side of the impeller and separated from the impeller, so that the impeller can be demolded smoothly and the surface damage is reduced, thereby achieving the effect of easy demolding. At the same time, the detachable design facilitates the cleaning and maintenance of the mold and improves the service life of the mold.

[0017] 3. By setting up temperature sensors, pressure sensors, heating coils, and air vents, the temperature sensors, pressure sensors, and heating coils are connected to an external controller during use, and compressed air is connected to the air vents. Through the synergistic effect between the temperature sensors, pressure sensors, heating coils, and air vents, the flow and curing process of gradient nanocomposite materials in the mold cavity can be precisely controlled, effectively reducing internal defects, improving the density, strength, and internal structural uniformity of the impeller, and meeting the high-precision performance requirements of the impeller.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-6 The first embodiment of this utility model discloses an integral molding mold for a gradient nanocomposite impeller, comprising: a lower mold 1, a plurality of insertion holes 101 are evenly provided on the top of the lower mold 1, a side mold 4 is inserted into the top of the insertion holes 101, a positioning pin 401 is fixedly connected to the bottom of the side mold 4, the positioning pin 401 is inserted into the inside of the insertion holes 101, and a heating coil 2 is fixedly connected to the middle of the lower mold 1.

[0031] It also includes: an upper mold 5, an outer ring 501 fixedly connected to the edge of the bottom end of the upper mold 5, a vent 505 fixedly connected to one end of the top end of the upper mold 5, an inner ring 506 fixedly connected to the middle of the bottom end of the upper mold 5, a temperature sensor 6 fixedly connected to one side of the bottom end of the inner ring 506, and a pressure sensor 7 fixedly connected to the other side of the bottom end of the inner ring 506.

[0032] By setting up temperature sensor 6, pressure sensor 7, heating coil 2, and vent 505, and connecting temperature sensor 6, pressure sensor 7, and heating coil 2 to an external controller during use, and connecting compressed air to vent 505, the temperature sensor 6 and pressure sensor 7, heating coil 2, and vent 505 work together to precisely control the flow and curing process of gradient nanocomposite materials in the mold cavity, effectively reducing internal defects, improving the density, strength, and internal structural uniformity of impeller 9, and meeting the high-precision performance requirements of impeller 9.

[0033] Example 2:

[0034] Reference Figure 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0035] Positioning grooves 102 are provided on both sides of the insertion hole 101. Positioning protrusions 402 are fixedly connected to both sides of the positioning pin 401. The positioning protrusions 402 and the positioning grooves 102 are connected to each other. A limiting groove 103 is provided at the bottom edge of the lower mold 1. A limiting ring 502 is fixedly connected to the bottom of the outer ring 501. The limiting ring 502 is snapped into the inside of the limiting groove 103.

[0036] By setting up the lower mold 1, side mold 4 and upper mold 5, the lower mold 1, side mold 4 and upper mold 5 are spliced ​​together to form the shape of impeller 9 in the internal cavity of the mold. Then, the nanocomposite material is injected from the injection port 504 and solidified inside the mold to form impeller 9. This enables the integral molding of gradient nanocomposite impeller, avoids many problems caused by assembly after split molding, and improves the overall performance and reliability of impeller 9.

[0037] Injection holes 503 are provided on both sides of the top of the upper mold 5. An injection port 504 is fixedly connected to the top of the injection hole 503. A through hole 507 is provided in the middle of the inner ring 506. A fixing bolt 3 is fixedly connected to the middle of the top of the lower mold 1. The fixing bolt 3 is inserted into the through hole 507. A fixing nut 8 is threaded on the other end of the fixing bolt 3. The fixing bolt 3 and the fixing nut 8 cooperate with each other to fix the lower mold 1 and the upper mold 5. An impeller 9 is provided between the lower mold 1 and the upper mold 5.

[0038] By setting the side mold 4, the molded impeller 9 and the side mold 4 are first separated from the lower mold 1 during demolding. Then, the side mold 4 is pulled out from the side of the impeller 9 and separated from the impeller 9, making the demolding of the impeller 9 smoother and thus achieving the effect of convenient demolding. At the same time, the detachable design facilitates the cleaning and maintenance of the mold and improves the service life of the mold.

[0039] The remaining structure is the same as that in Example 1.

[0040] The workflow of this utility model is as follows:

[0041] First, the side molds 4 are inserted into the holes 101 in sequence. The positioning grooves 102 and positioning protrusions 402 make the side molds 4 more neatly arranged at the top of the lower mold 1, improving the flatness of the surface of the impeller 9 after molding. Then, the upper mold 5 is snapped onto the top of the lower mold 1 and the fixing nut 8 and fixing bolt 3 are tightened to fix the upper mold 5 and the lower mold 1. With the arrangement of the lower mold 1, side molds 4 and upper mold 5, the lower mold 1, side molds 4 and upper mold 5 are spliced ​​together to form the shape of the impeller 9 in the cavity inside the mold. Then, the nanocomposite material is injected from the injection port 504 and solidified inside the mold to form the impeller 9. This enables the integral molding of the gradient nanocomposite impeller, avoiding many problems caused by assembly after split molding, and improving the overall performance and reliability of the impeller 9.

[0042] Secondly, the nanocomposite material is injected into the mold through the injection port 504. There are two injection ports 504, which are symmetrically distributed at the top of the upper mold 5, so as to achieve a more uniform distribution of the nanocomposite material inside the mold. During the injection process, the temperature sensor 6 and the pressure sensor 7 detect the temperature and pressure inside the cavity in real time and transmit the data to the external controller. The temperature sensor 6, the pressure sensor 7, the heating coil 2 and the vent 505 are set up.

[0043] When in use, the temperature sensor 6, pressure sensor 7, and heating coil 2 are connected to an external controller, and the air vent 505 is connected to compressed air. Through the synergistic effect between the temperature sensor 6 and pressure sensor 7, the heating coil 2, and the air vent 505, the flow and curing process of the gradient nanocomposite material in the mold cavity can be precisely controlled, effectively reducing internal defects, improving the density, strength, and internal structural uniformity of the impeller 9, and meeting the high-precision performance requirements of the impeller 9.

[0044] Finally, when demolding is required, first unscrew the fixing nut 8 from the fixing bolt 3, then separate the upper mold 5 from the lower mold 1, then separate the formed impeller 9 and the side mold 4 together from the lower mold 1, and then pull the side mold 4 out from the side of the impeller 9 to separate it from the impeller 9, so that the impeller 9 can be demolded more smoothly, thereby achieving the effect of convenient demolding. At the same time, the detachable design facilitates the cleaning and maintenance of the mold and improves the service life of the mold.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
