Description

Technical Field

[0001] This utility model relates to the technical field of investment casting, and in particular to a ceramic pouring cup with a detachable cover plate function. Background Technology

[0002] In existing technologies, ceramic pouring cups are commonly used for some high-precision high-temperature alloy castings. First, due to their smooth surface and precise dimensions, ceramic pouring cups can reduce the flow resistance of the melt, thereby improving fluidity and increasing the redundancy of the process. Second, due to the microscopic pore structure of ceramics, they can adsorb impurities in the melt, further preventing the formation of inclusions in the casting. Finally, because ceramics have good heat insulation properties, they can ensure that the pouring cup continues to provide feeding for the runner and casting after being filled with molten metal.

[0003] However, using ceramic gating cups requires a matching cover plate to protect the inside of the gating cup from contamination by the slurry. Therefore, traditional investment casting requires prying open the cover plate to obtain the shell containing the ceramic gating cup. This structure has certain disadvantages: 1. It is highly dangerous, producing a lot of dust and the gating cup may break due to vibration from cutting / prying open the shell; 2. A broken gating cup may have cracks, slag, and the fracture surface may react with the molten metal, thus preventing the ceramic gating from functioning effectively. In severe cases, it can lead to the casting being scrapped due to metal inclusions. Utility Model Content

[0004] The purpose of this utility model is to provide a ceramic pouring cup with a detachable cover plate function, so as to alleviate the technical problems existing in the prior art, such as the pouring cup being damaged due to cutting or prying vibration caused by large dust, and the casting being scrapped due to metal inclusion caused by the damage of the pouring cup.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a ceramic pouring cup with a detachable cover plate function, including a pouring cup assembly, a cover plate and an inflation assembly, wherein the cover plate is provided at the mouth end of the pouring cup assembly;

[0007] The inflation component is connected to the pouring cup assembly and abuts against the cover plate. The inflation component is used to lift the cover plate after inflation so as to separate the cover plate from the pouring cup assembly.

[0009] The inflation component is connected to the mouth end of the pouring cup body, and the inflation component is used to lift the cover plate after inflation, so as to separate the cover plate from the pouring cup body.

[0010] Furthermore, the pouring cup assembly also includes a wax pattern base, which is connected to the end of the pouring cup body away from the rim.

[0011] Furthermore, the pouring cup assembly also includes a mold shell, which covers the outer wall of the pouring cup body and the wax pattern base, and the mold shell is connected to the inflation assembly.

[0012] Furthermore, the inflation components are distributed circumferentially along the rim of the pouring cup body, and one end of the inflation components is used to connect to an external inflation device.

[0013] Furthermore, the inflation assembly includes a covering tube and an inflation tube. The covering tube is distributed circumferentially along the cup mouth end of the pouring cup body. An annular accommodating space is provided inside the covering tube, and a through groove is provided circumferentially at the top of the covering tube.

[0014] The inflation tube is located within the accommodating space, and one end of the inflation tube is connected to the inflation device. The inflation tube is used to expand out of the through groove after inflation to lift the cover plate.

[0015] Furthermore, the covering tube is made of a hard metal material, and the covering tube is used to limit the inflation tube so that the inflation tube expands out of the through groove after inflation.

[0016] Furthermore, the ceramic pouring cup with a detachable cover plate also includes a connecting component, one end of which is connected to the wax pattern base, and the other end of which is connected to the cover plate.

[0017] Furthermore, the connecting assembly includes a core and a release nut, one end of the core being connected to the wax pattern base, and the other end being connected to the cover plate via the release nut.

[0018] Furthermore, the cover plate has through holes;

[0037] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Example 1

[0039] This embodiment provides a ceramic pouring cup with a detachable cover plate function, see reference. Figure 1 The ceramic pouring cup with a detachable cover plate includes a pouring cup assembly 1, a cover plate 2, and an inflation assembly 4. The pouring cup assembly 1 has a cover plate 2 at its mouth. The inflation assembly 4 is connected to the pouring cup assembly 1 and abuts against the cover plate 2. The inflation assembly 4 is used to lift the cover plate 2 after inflation, so that the cover plate 2 is separated from the pouring cup assembly 1.

[0040] This utility model embodiment at least alleviates the technical problems existing in the prior art, such as the breakage of the pouring cup due to vibration caused by cutting or prying due to large amounts of dust, and the scrapping of castings due to metal inclusions caused by damage to the pouring cup.

[0041] In this embodiment of the present invention, the cover plate 2 is disposed at the mouth end of the pouring cup assembly 1, and an inflation component 4 is provided on the outside of the pouring cup assembly 1, the inflation component 4 abutting against the cover plate 2; in use, the inflation component 4 is inflated so that the inflation component 4 lifts the cover plate 2 after inflation and expansion, thereby separating the cover plate 2 from the pouring cup assembly 1.

[0042] Compared with the prior art, the ceramic pouring cup with a detachable cover plate provided in this utility model embodiment is achieved by setting an inflation component 4 at the outlet end of the pouring cup assembly 1, and inflating the inflation component 4 with an external inflation device during use. This allows the cover plate 2 to be lifted after the inflation component 4 expands, thereby separating the cover plate 2 from the pouring cup assembly 1 and avoiding damage to the pouring cup assembly 1. This also overcomes the problem of metal inclusions in the casting causing scrap.

[0043] In an optional implementation of this embodiment, refer to Figure 1The pouring cup assembly 1 includes a pouring cup body 11, which is connected to a cover plate 2; an inflation assembly 4 is connected to the mouth end of the pouring cup body 11, and the inflation assembly 4 is used to lift the cover plate 2 after inflation, so that the cover plate 2 is separated from the pouring cup body 11.

[0044] Specifically: the pouring cup body 11 is connected to the cover plate 2. The pouring cup body 11 is a frustum-shaped cup structure, and its top is set as the cup mouth end. The outer wall of the cup mouth end of the pouring cup body 11 is provided with an inflation component 4. In use, the inflation component is inflated so that the inflation component 4 expands, thereby causing the cover plate 2 to be lifted and separated from the pouring cup body 11.

[0045] Furthermore, referring to Figure 1 The pouring cup assembly 1 also includes a wax pattern base 13, which is connected to the end of the pouring cup body 11 away from the rim.

[0046] Specifically: the wax pattern base 13 is connected to the end of the pouring cup body 11 away from the cup mouth; the end of the pouring cup body 11 away from the cup mouth is connected through the wax pattern base 13, and the wax pattern base 13 is used to seal the bottom of the pouring cup body 11.

[0047] Furthermore, referring to Figure 1 The pouring cup assembly 1 also includes a shell 12, which covers the outer wall of the pouring cup body 11 and the wax pattern base 13, and the shell 12 is connected to the inflation assembly 4.

[0048] Specifically: the shell 12 covers the outer wall of the pouring cup body 11 and the wax pattern base 13, and the shell 12 is connected to the inflation component 4; in use, the shell 12 is coated on the outer wall of the pouring cup body 11 and the wax pattern base 13, and after the shell 12 is made, compressed air of a certain pressure is injected into the inflation component 4 to make the inflation component 4 expand, and then the pressure generated by the expansion of the inflation component 4 is used to directionally crack the shell 12 nearby, so as to lift the cover plate 2.

[0049] In an optional implementation of this embodiment, refer to Figure 1 or Figure 2 The inflation component 4 is distributed circumferentially along the mouth end of the pouring cup body 11, and one end of the inflation component 4 is used to connect to an external inflation device.

[0050] Specifically: the inflation component 4 is distributed circumferentially along the cup mouth end of the pouring cup body 11, and one end of the inflation component 4 is used to connect to an external inflation device, while the other end is in a closed state, so as to form an inflation component 4 similar to the letter Q and surround the cup mouth end of the pouring cup body 11.

[0051] Furthermore, referring to Figure 2 or Figure 3 The inflation assembly 4 includes a covering tube 41 and an inflation tube 42. The covering tube 41 is distributed circumferentially along the cup mouth end of the pouring cup body 11. An annular accommodating space is provided inside the covering tube 41, and a through groove is provided circumferentially at the top of the covering tube 41. The inflation tube 42 is located in the accommodating space, and one end of the inflation tube 42 is connected to the inflation device. The inflation tube 42 is used to expand out of the through groove after inflation to lift the cover plate 2.

[0052] Specifically: the covering tube 41 is distributed circumferentially along the rim of the pouring cup body 11, with one end of the covering tube 41 being open and the other end being closed; while one end of the inflation tube 42 is closed and the other end is open, with the open end of the inflation tube 42 used to connect to an external inflation device to inflate the inflation tube 42. A through groove is provided on the upper surface of the covering tube 41 along its extension direction, so that after the inflation tube 42 is filled with gas of not less than 0.5 MPa, it expands. Due to the limiting effect of the covering tube 41, the inflation tube 42 expands and passes through the through groove, thus limiting the inflation tube 42 through the covering tube 41, preventing the inflation tube 42 from squeezing the pouring cup body 11 after inflation and expansion, and causing the inflation tube 42 to generate directional pressure after expansion.

[0053] Furthermore, referring to Figure 2 or Figure 3 The covering tube 41 is made of hard metal material and is used to limit the inflation tube 42 so that the inflation tube 42 expands out of the through groove after inflation.

[0054] Specifically: the covering tube 41 is made of a hard metal material, preferably steel, and the outer diameter of the covering tube 41 is 10mm, the inner diameter is 8mm, and the minimum circumference of the covering tube 41 is slightly larger than the maximum circumference of the pouring cup body 11 by 2mm-3mm; in use, since the covering tube 41 is made of a hard material, it can effectively limit the inflation tube 42 after inflation and expansion, so as to prevent the inflation tube 42 from applying pressure to the pouring cup body 11 after inflation.

[0055] In an optional implementation of this embodiment, refer to Figure 1 The ceramic pouring cup with a detachable cover plate also includes a connecting component 3, one end of which is connected to the wax pattern base 13, and the other end of which is connected to the cover plate 2.

[0056] Specifically: one end of the connecting component 3 is connected to the wax pattern base 13, and the other end of the connecting component 3 is connected to the cover plate 2; preferably, the bottom of the connecting component 3 is connected to the center of the wax pattern base 13, and the connecting component 3 is located inside the pouring cup body 11, while its other end is connected to the cover plate 2 to support the cover plate 2.

[0057] Furthermore, referring to Figure 1 The connecting component 3 includes a core 31 and a release nut 32. One end of the core 31 is connected to the wax pattern base 13, and the other end is connected to the cover plate 2 via the release nut 32.

[0058] Specifically: one end of the core 31 is connected to the wax pattern base 13, and the other end is connected to the cover plate 2 via a release nut 32; preferably, the bottom of the core 31 is fixedly connected to the wax pattern base 13, while the top of the core 31 is connected to the release nut 32. The release nut 32 is used to abut against the top of the cover plate 2 to support the cover plate 2, and the position of the release nut 32 on the core 31 can be adjusted, thereby making it more universally applicable.

[0059] Furthermore, referring to Figure 1 The cover plate 2 has a through hole; the separation nut 32 includes a support platform and a protrusion on the top of the support platform, the protrusion passes through the through hole so that the support platform is supported on the bottom surface of the cover plate 2; the outer wall of the core 31 is threaded, and the separation nut 32 has a threaded hole, and the separation nut 32 is threadedly connected to the core 31.

[0060] Specifically: the cover plate 2 has a circular through hole at its center, and the separating nut 32 includes a support platform and a protrusion on the top of the support platform. The protrusion has a cylindrical structure. In use, the cylindrical protrusion is passed through the through hole so that the support platform located below the protrusion abuts against the bottom surface of the cover plate 2. The separating nut 32 has a threaded hole in the vertical direction, and the outer wall of the core rib 31 has threads. The separating nut 32 is threadedly connected to the core rib 31, so that its position on the core rib 31 can be adjusted by rotating the separating nut 32.
