Abstract
Description
Technical Field
[0001] The present application belongs to the field of casting molds, and in particular relates to a vertical casting mold structure for small guide vanes. Background Art
[0002] In the traditional guide vane precision casting process, the casting mold is usually placed with a large flat surface facing upward. Since the pouring riser is usually set directly above the casting mold, when the molten steel is injected into the mold, it will directly impact the guide vane shell. Since the filling angle and speed are often difficult to accurately control, this direct impact often causes the molten steel to splash at the shell product part. Once the splashing molten steel contacts the shell, it will quickly solidify to form steel beans. These steel beans will adhere to the inner surface of the shell and are difficult to remove, which will cause bean pits to form on the plane of the casting product, seriously affecting the surface quality and aesthetics of the casting product. In addition, the turbulent molten steel collides with each other inside the shell, which will not only produce multiple gas streams and cause wrinkled flow marks on the surface of the casting. Moreover, these gases are difficult to discharge during the solidification process of the casting, and eventually defects such as pores or slag inclusions will be formed inside the casting. These defects not only reduce the mechanical properties of the casting product, but also may affect its service life and reliability. Therefore, it is necessary to solve the above technical problems. Utility Model Content
[0003] The purpose of the embodiments of the present application is to provide a vertical casting mold structure for a small guide vane to solve the technical problem of poor precision casting quality of the guide vane in the prior art.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a vertical casting mold structure of a small guide vane, comprising:
[0005] A guide vane mold shell, two of which are coaxially spaced apart, each of which forms a cavity for molding a target guide vane;
[0006] A casting body is spaced apart from the guide vane mold shell and forms a main flow channel with one end open, wherein the main flow channel extends in a direction perpendicular to the axial direction of the cavity and the projection of the cavity in its own axial direction is entirely located within the extension range of the main flow channel;
[0007] A bottom connector is connected between the casting body and the guide vane mold shell to form a bottom flow channel connecting the main flow channel and the cavity. The bottom flow channel is perpendicular to the main flow channel and connected to an end of the main flow channel away from its own opening.
[0008] Optionally, the vertical casting mold structure further includes a top connector connected between the casting body and the guide vane mold shell;
[0009] The top connector and the bottom connector are symmetrical about the central axis of the cavity, and a top flow channel connecting the main flow channel and the cavity is formed on the top connector.
[0010] Optionally, the two guide vane molds are symmetrical about the main flow channel on the casting body.
[0011] Optionally, the vertical casting mold structure further includes an intermediate connector connected between the guide vane mold shells;
[0012] The intermediate connector is located between the top connector and the bottom connector in the extension direction of the main flow channel, and a uniform flow channel connecting the mold cavities at both sides is formed on the intermediate connector.
[0013] Optionally, the vertical casting mold structure further includes a feeding body connected to the intermediate connector;
[0014] A cavity connected to the uniform flow channel is formed inside the feeding body.
[0015] Optionally, the vertical casting mold structure further includes an intermediate body connected between the casting body and the guide vane mold shell;
[0016] The intermediate body forms a conical shell extending around the central axis of the cavity, and a middle flow channel communicating with the main flow channel and the cavity is also formed on the intermediate body.
[0017] Optionally, at least two intermediate bodies are provided and are symmetrical about the central axis of the main flow channel.
[0018] The beneficial effect of the vertical casting mold structure of the small guide vane provided in the present application is that: compared with the prior art, in the vertical casting mold structure of the small guide vane of the present application, since the projection of the cavity in its own axial direction is located within the extension range of the main channel, and since the bottom branch channel connecting the main channel and the cavity is perpendicular to the main channel and connected to the end of the main channel away from its own opening, when the casting material is injected into the main channel from the opening of the main channel, it will not directly enter the cavity, but will first pass through the bottom branch channel perpendicular to the main channel and then enter the bottom of the cavity, thereby effectively preventing the splashing casting material from solidifying on the surface of the cavity. At the same time, the two guide vane mold shells are symmetrically arranged on both sides of the main channel, which effectively improves the stability of the entire casting mold, and the radial upright method is adopted to make the casting defect position away from the guide vane position, which can be removed in the subsequent mechanical processing process, which is beneficial to significantly improve the precision casting quality of the guide vane, which is far superior to the prior art.
