Description

Technical Field

[0001] This utility model relates to the field of continuous casting tooling and mold technology, and in particular to a tooling and mold with adjustable thickness. Background Technology

[0002] Continuous casting is a processing technology that continuously pours molten metal into a mold, achieving continuous metal forming through the continuous movement of the mold. Existing continuous casting molds include a crystallizer and a dummy head. The crystallizer is a bottomless mold with a specific cross-sectional shape. The dummy head is an intermediate device connecting the dummy rod and the crystallizer during continuous casting, and it is mounted on the dummy rod. Before pouring, the dummy head is inserted into the crystallizer, acting as a movable bottom to form a tooling mold, preventing the molten steel poured into the crystallizer from leaking out. After pouring begins, as the molten steel solidifies, the billet and the dummy head solidify together, and the dummy rod is pulled out and moved downwards by the pull rollers. After the dummy head passes the pull rollers, the dummy rod and the billet are separated and sent away for use in the next pour.

[0003] Due to the diversity of alloys produced, tooling dies with different widths and / or thicknesses of crystallizers and ingot heads are required. Various specifications of tooling dies need to be readily available. Frequent tooling die changes are necessary when casting different alloys, which is time-consuming and impacts production efficiency. Existing tooling dies can only be adjusted in width, not thickness. Therefore, a tooling die with adjustable thickness is needed to accommodate the diversity of alloys produced, while also reducing downtime for continuous casting machine tooling changes and improving efficiency. Summary of the Invention

[0004] To address the problem of frequent replacement of tooling molds of different sizes in existing tooling molds, this invention provides an adjustable thickness tooling mold. By setting a thickness adjustment device on the ingot head and setting an adjustable connecting plate and an adjustable small surface assembly on the crystallizer, the width and thickness of the tooling mold can be adjusted, reducing the time spent on frequently changing tooling molds of different sizes and improving production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable thickness tooling mold includes a crystallizer and a derrick head. The derrick head is equipped with a thickness adjustment device, and the crystallizer is located at the upper part of the derrick head. The crystallizer includes two large surface water tanks and an adjustable small surface assembly. The two large surface water tanks are symmetrically arranged, and a large panel is connected to the upper part of the large surface water tanks. Adjustable connecting plates connecting the two large surface panels are provided at both ends of the large surface panels. The adjustable small surface assembly is located between the two large surface water tanks. The adjustable small surface assembly is used to adjust the width and thickness of the mold cavity.

[0007] Furthermore, the thickness adjustment device is a shim, which is detachably connected to the ingot head, allowing for adjustable thickness of the ingot head. The shim enables the ingot head to be adjusted in accordance with changes in the thickness of the crystallizer without requiring replacement, thus improving the flexibility of tooling and mold use.

[0008] Furthermore, one end of the adjustable connecting plate is fixedly connected to one of the large panels, and the other end is slidably connected to the other large panel. This facilitates adjustment of the distance between the two large water tanks. The adjustable connecting plate allows for adjustment of the distance between the large water tanks after replacing them with smaller water tank assemblies of different sizes, to accommodate the new smaller water tanks.

[0009] Furthermore, one end of the adjustable connecting plate is fixedly connected to one of the large panels, and the other end has multiple elongated holes. The large panel corresponding to the elongated holes has multiple holes, and a connector is provided in the elongated hole. The connector is connected to the hole on the large panel through the elongated hole.

[0010] Furthermore, the adjustable facet assembly includes at least two sets of facet water tank assemblies with different thicknesses. Each facet water tank assembly includes two facet water tanks, and a small panel is fixedly connected to the upper part of each facet water tank. The small panel is slidably connected to the large panel to adjust the width. By setting facet water tank assemblies of different thicknesses, the thickness of the tooling mold can be adjusted by replacing the facet water tank assemblies of different thicknesses, without having to replace the entire crystallizer. This facilitates adaptation to the size requirements of different alloy castings, saves time on changing the crystallizer and ingot head, and improves production efficiency.

[0011] Furthermore, both sides of the small panel are provided with sliding grooves, and a second connector is installed in the sliding groove. The large panel is provided with multiple threaded holes corresponding to the sliding grooves, and the second connector passes through the sliding groove and connects with the threaded holes. The width of the tooling mold cavity can be changed by adjusting the distance between the two small water tanks. The sliding grooves on the small panel, with bolts installed in the grooves to connect with the large panel, facilitate fixation after adjusting the distance between the two small panels.

[0012] Furthermore, a water filter element is connected to the small panel, and the water filter element passes through the small panel and is installed inside the small water tank; a water distribution valve is connected to the side of the small water tank. The water filter element filters impurities from the cooling water in the crystallizer, and the water distribution valve evenly distributes the water flow into the small water tank.

[0013] Furthermore, a ruler is fixed at the connection between the small panel and the large panel to facilitate timely observation of the adjustment of the width of the small panel.

[0014] The beneficial effects of this utility model through the above technical solution are:

[0015] This invention achieves adjustable width and thickness of the tooling mold by setting a thickness adjustment device on the ingot head and setting an adjustable connecting plate and adjustable small surface assembly on the crystallizer, thereby reducing the time spent on frequently changing tooling molds of different sizes and improving production efficiency.

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0025] like Figures 1-7As shown, an adjustable-thickness tooling mold includes a derrick head 12 and a crystallizer. The derrick head 12 is equipped with a thickness adjustment device, which is a shim 13. Side plates 14 are fixed to both sides of the derrick head 12. The shim 13 is bolted to the side plates 14 for easy disassembly. The shim 13 and the side plates 14 form a frame structure fixed to the outer wall of the derrick head 12. In this embodiment, the thickness of the shim 13 is 120mm. By using the shim 13, the thickness of the derrick head 12 can be adjusted to accommodate changes in the crystallizer thickness without disassembling the derrick head 12, thus improving the flexibility of the tooling mold.

[0026] A crystallizer is connected to the upper part of the ingot head 12. The crystallizer includes two large water tanks 4 and an adjustable small water tank assembly. The two large water tanks 4 are symmetrically arranged. A large panel 1 is fixedly connected to the upper part of the large water tank 4. The large panel 1 is used to press and seal the large water tank 4. In this embodiment, the existing structures of the large water tank 4 and the large panel 1 are applicable to this utility model.

[0027] Adjustable connecting plates 3 are provided at both ends of a large panel 1 to connect two large panels 1. One end of the adjustable connecting plate 3 is fixedly connected to one of the large panels 1, and the other end is slidably connected to the other large panel 1. Specifically, one end of the adjustable connecting plate 3 has multiple fixing holes, and the other end has multiple elongated holes 8, with connectors 5 installed inside the elongated holes 8. The large panel 1 corresponding to the elongated holes 8 has multiple holes arranged linearly. The adjustable connecting plate 3 is fixedly connected to one of the large panels 1 by bolts and fixing holes, and the other end is connected to the corresponding hole on the large panel 1 by connectors 5. When adjusting the distance between the two large panels 1, the position of the adjustable connecting plate 3 and the holes between the two large panels 1 can be adjusted, and then fixed by connectors 5. When the distance to be adjusted is too long, adjustable connecting plates 3 of different lengths can be replaced to connect to the large panels 1 to adapt to the adjustment needs.

[0028] The adjustable small-face component is positioned between the two large-face water tanks 4. The adjustable small-face component includes at least two sets of small-face water tanks of different thicknesses. After adjusting the distance between the two large-face water tanks 4, a small-face water tank set matching the adjusted distance is replaced to accommodate the larger-face water tanks 4, thereby achieving adjustment of the thickness of the tooling mold cavity. In this embodiment, two sets of small-face water tanks are used.

[0029] Each set of small-faced water tanks includes two small-faced water tanks 11, which are symmetrically arranged between two large-faced water tanks 4. Each small-faced water tank 11 is fixedly connected to a small panel 2. The existing structures of the small-faced water tanks 11 and small panels 2 are applicable to this utility model, so the structures of the small-faced water tanks 11 and small panels 2 will not be described in detail here. In this embodiment, the thickness of the small-faced water tanks 11 in one set of small-faced water tanks is 380mm, and the thickness of the small-faced water tanks 11 in the other set of small-faced water tanks is 500mm.

[0030] Each small panel 2 is connected to two large panels 1 at both ends. The small panel 2 can drive the small water tank 11 to slide between the large water tanks 4 to adjust the width of the tooling mold cavity. Specifically, each end of the small panel 2 is provided with a sliding groove 6, and a connecting piece 2 15 is provided in the sliding groove 6. The large panel 1 is provided with multiple threaded holes at the corresponding positions of the sliding groove 6. After the small panel 2 slides on the large panel 1, it is connected and fixed to the large panel 1 by the connecting piece 2 15 passing through the sliding groove 6 and the threaded holes. In this embodiment, both the connecting piece 1 5 and the connecting piece 2 15 are bolts.

[0031] To facilitate observation of the adjustment of the width of the small panel 2, scales 7 are provided on both ends of the small panel 2, and the scales 7 are fixed on the large panel 1.

[0032] A water filter element 9 is fixed to the top of the small panel 2. The water filter element 9 passes through the small panel 2 and is installed inside the small water tank 11 to facilitate the filtration of impurities in the cooling water entering the small water tank 11. A water distribution valve 10 is connected to the side of the small water tank 11 to facilitate the adjustment of the flow rate and pressure inside the small water tank 11.

[0033] When a 380mm thick mold is required, remove the shim 13 from the spindle head 12, place two 380mm small surface water tanks 11 between two large surface water tanks 4, adjust the distance between the two small surface water tanks 11, and then fix the small panel 2 to the large panel 1 through connector 2 15. After adjusting the position between the elongated hole 8 of the adjustable connecting plate 3 and the large panel 1, fix it through connector 1 5.

[0034] When a 500mm thick mold is required, the shim 13 is fixed to the upper part of the spindle head 12 with bolts. Two 500mm small surface water tanks 11 are placed between two large surface water tanks 4. After adjusting the distance between the two small surface water tanks 11, the small panel 2 is fixed to the large panel 1 through the connector 2 15. After adjusting the position between the elongated hole 8 of the adjustable connecting plate 3 and the large panel 1, it is fixed through the connector 1 5.

[0035] When it is necessary to adjust the width of the tooling mold cavity, the distance between the two small water tanks 11 is adjusted by sliding the two small water tanks 11. Then, the connecting piece 2 15 passes through the slide groove 6 and connects to the threaded hole on the large panel 1, thereby realizing the adjustment of the width of the tooling mold cavity.
