Description

Technical Field

[0001] The present application relates to the technical field of easy-to-cut casting sheets, for example, to an easy-to-cut casting sheet. Background Art

[0002] At present, in the process of metal casting, two openings are set in the mold, one is the filling port, which is set on the side or bottom of the mold for adding molten metal to the mold, and the other is the riser set on the upper part of the mold. When the molten metal in the mold is full, it is necessary to continue to add so that the molten metal in the mold overflows from the riser into the riser sleeve. The riser sleeve can slow down the cooling time of the molten metal in the ground mouth, which can prevent the molten metal at the riser from cooling too quickly, causing the molten metal near the ground mouth in the mold to cool too quickly, and prevent the uneven cooling speed between the molten metal in the mold from causing different stresses in the later castings to crack, and an easy-to-cut sheet is usually provided between the mold and the riser sleeve, which can facilitate the cutting of the ground mouth on the casting in the later stage, and reduce the connection strength between the casting and the casting in the riser sleeve.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0004] Traditional easy-to-cut pieces are generally circular plate-shaped structures, and the circular edges of the easy-to-cut pieces are perpendicular to the surface of the easy-to-cut pieces. When installing the easy-to-cut pieces, the easy-to-cut pieces can only be fixed by hard clamping of the mold. The mold and the easy-to-cut pieces are connected by clamping friction. The connection strength between the mold and the easy-to-cut pieces is low, which can easily cause the easy-to-cut pieces to separate from the mold. In addition, the traditional casting method uses a filling port and a riser for casting. The molten metal in the filling port and the riser can only be re-smelted after cooling, which will seriously cause a waste of resources. Utility Model Content

[0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0006] The disclosed embodiment provides an easy-to-cut sheet for casting, so as to solve the problem that the connection between the easy-to-cut sheet and the mold is unstable, so that the molten metal cannot be poured through the riser.

[0007] In some embodiments, the easy-to-cut piece for casting includes: a main body is a circular plate-like structure; a through hole is arranged on the main body, the central axis of the main body coincides with the central axis of the through hole, and the through hole passes through both sides of the main body; a limiting groove is arranged around the circular side edge of the main body, the limiting groove is recessed from the side edge of the main body to the inside of the main body, and the limiting groove is used to engage and connect with the casting mold.

[0008] In some embodiments, a tapered hole is provided on one side of the body, and the tapered hole is connected to the through hole.

[0009] In some embodiments, a circular positioning ring is provided on the side of the body, the positioning ring is provided on the side where the tapered hole is provided, and the positioning ring is provided outside the tapered hole.

[0010] In some embodiments, the cross-section of the limiting groove is a triangular structure.

[0011] In some embodiments, the cross-section of the limiting groove is a semicircular structure.

[0012] In some embodiments, a circular boss is provided on the outer side of the body for thickening the side of the body, and the boss is arranged on the outside of the positioning ring.

[0013] In some embodiments, the body is made of clay, and the body is formed by pressing the clay.

[0014] In some embodiments, a fracture groove is formed on the conical hole, and the fracture groove extends from the center of the conical hole to the side.

[0015] In some embodiments, the inner side wall of the positioning ring is provided with a first notch recessed inwardly.

[0016] In some embodiments, the inner side wall of the boss is provided with a second notch recessed inwardly.

[0017] The easy-to-cut sheet for casting provided in the embodiments of the present disclosure can achieve the following technical effects:

[0018] By setting a limiting groove on the side of the easy-to-cut piece, the easy-to-cut piece can be clamped on the mold through the limiting groove, thereby increasing the connection strength between the mold and the easy-to-cut piece. After the connection strength between the easy-to-cut piece and the mold is increased, the molten metal can be directly poured through the riser, so that the filling port can be removed, reducing the waste of molten metal outside the mold, reducing the subsequent smelting steps of the metal block with the filling port, and reducing the waste of resources.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0036] Combination Figure 1-5 As shown, the embodiment of the present disclosure provides an easy-to-cut sheet for casting, including: a main body 100 is a circular plate-like structure; a through hole 200 is arranged on the main body 100, the central axis of the main body 100 coincides with the central axis of the through hole 200, and the through hole 200 passes through both sides of the main body 100; a limiting groove 300 is arranged around the circular side of the main body 100, the limiting groove 300 is recessed from the side of the main body 100 to the inside of the main body 100, and the limiting groove 300 is used to be engaged with the casting mold.

[0037] The easy-to-cut sheet provided by the embodiment of the present disclosure is adopted, and the main body 100 is a circular plate-like structure, and a circular through hole 200 is arranged in the middle of the main body 100. The circular through hole on the main body 100 can reduce the diameter of the connecting part between the metal in the riser and the casting, so as to facilitate the removal of the riser part solidified in the later stage. The plate-like main body 100 can conduct heat quickly, and can quickly balance the temperature between the metal in the riser and the casting main body 100, and prevent the temperature difference between the casting at the riser and the casting main body 100 from being too large. The molten metal retained in the riser sleeve at the riser can slow down the speed of the casting temperature drop at the riser, so that the overall temperature of the casting can drop steadily and evenly, and prevent the casting main bodies 100 from having different temperature drop speeds, and prevent the stress difference between the casting main bodies 100 from being too large, causing the casting main body 100 to In order to solve the problem of cracks or hidden scratches, a limiting groove 300 is arranged around the circular side of the main body 100, and the limiting groove 300 is recessed toward the center line of the main body 100. When manufacturing the mold, it is only necessary to reserve a protrusion matching the limiting groove 300 on the part of the mold where the easy-to-cut sheet is installed. The main body 100 can be stably clamped in the mold through the protrusion, which increases the connection strength between the easy-to-cut sheet and the mold. In this way, the molten metal can be added through the riser during casting, and the filling port on the mold can be omitted. Because the pipe of the filling port is longer when filling through the filling port, when the casting is completely cooled, there will be a section of metal in the cold zone in the filling port. This section of metal also needs to be removed from the casting, and needs to be re-smelted as waste later, which will increase the energy required for smelting and cause unnecessary waste.

[0038] Combination Figure 1-5 As shown, optionally, a tapered hole 201 is provided on one side of the body 100, and the tapered hole 201 is connected to the through hole 200. In this way, the thickness of the middle of the body 100 can be reduced through the tapered hole 201, and the thickness of the body 100 gradually increases from the through hole 200 to the side of the body 100, so that the end of the metal at the riser close to the casting is a circular boss 102 structure, which can reduce the distance between the metal at the riser and the casting, and can better balance the temperature between the metal at the riser and the casting. The tapered hole 201 can facilitate the molten metal to flow into the mold through the through hole 200, and prevent the molten metal from remaining on the body 100 when it is not fully poured during casting.

[0039] Combination Figure 1-5 As shown, optionally, a circular positioning ring 101 is provided on the side of the body 100, and the positioning ring 101 is provided on the side where the tapered hole 201 is provided, and the positioning ring 101 is provided outside the tapered hole 201. In this way, by providing the positioning ring 101 on the side of the body 100 and sleeved with a riser sleeve on the positioning ring 101, the positioning ring 101 can limit the position of the riser sleeve, thereby preventing the riser sleeve from being separated from the easy-to-cut sheet body 100 during the casting process.

[0040] Combination Figure 3 As shown, optionally, the cross section of the limiting groove 300 is a triangular structure. In this way, by setting the limiting groove 300 as a triangular groove structure, it is convenient to clamp the easy-to-cut sheet body 100 on the mold, and the cross section of the limiting groove 300 is a triangular structure, which can increase the connection strength of the limiting groove 300.

[0041] Combination Figure 4 As shown, optionally, the cross section of the limiting groove 300 is a semicircular structure. In this way, by setting the semicircular limiting groove 300, the accommodating volume of the limiting groove 300 can be made larger, the protruding boss 102 of the mold can be made larger, and the connection between the mold and the limiting groove 300 can be made more stable.

[0042] Combination Figure 1-5 As shown, optionally, a circular boss 102 for thickening the side thickness of the body 100 is provided on the outer side of the body 100, and the boss 102 is provided on the outside of the positioning ring 101. In this way, since the thickness of the body 100 is small, the width that the limiting groove 300 can accommodate is small. By providing the circular boss 102 on the side edge of the body 100, the width of the limiting groove 300 can be increased, thereby increasing the stability of the clamping between the mold and the body 100, and preventing the easy-to-cut board body 100 from being separated from the mold.

[0043] Combination Figure 1-5 As shown, optionally, the body 100 is made of clay, and the body 100 is pressed and formed by clay. In this way, by using clay as the main material, the easy-to-cut sheet can be pressed and formed conveniently, and the dry clay has good heat resistance and firmness.

[0044] Combination Figure 1-5 As shown, optionally, a fracture groove 202 is provided on the conical hole 201, and the fracture groove 202 is extended from the center to the side of the conical hole 201. In this way, by providing the fracture groove 202 on the conical hole 201, it is convenient to remove the easy-to-cut piece after casting. The easy-to-cut piece body 100 can be easily broken through the fracture groove 202, and the easy-to-cut piece body 100 can be easily removed from the casting, thereby preventing the problem that the easy-to-cut piece is set on the casting and is inconvenient to remove.

[0045] Combination Figure 1-5 As shown, optionally, the inner side wall of the positioning ring 101 is provided with a first notch 103 which is recessed inwardly. In this way, the first notch 103 can also facilitate the breaking of the positioning ring 101. Since the positioning ring 101 is thick, it is difficult to break it when removing the easy-to-cut sheet body 100. The first notch 103 can facilitate the breaking of the positioning ring 101.

[0046] Combination Figure 1-5As shown, optionally, the inner side wall of the boss 102 is provided with a second indentation 104 which is recessed inwardly. In this way, the boss 102 can be easily broken through the second indentation 104. Since the boss 102 is thick, it is difficult to break it when removing the easy-to-cut sheet body 100. The boss 102 can be easily broken through the second indentation 104.
