Description

Technical Field

[0001] This utility model relates to the field of electrofused brick production technology, and in particular to a graphite riser structure for electrofused brick casting. Background Technology

[0002] Graphite riser structures for electrofused brick casting are mainly used in the riser system of electrofused brick production. Riseres are an indispensable part of the electrofused brick casting process, playing a role in maintaining the fluidity of the melt and aiding in venting. Graphite, as a riser material, has good thermal conductivity, thermal shock resistance, and chemical stability, and is therefore often used in the casting process of high-temperature melts.

[0003] The working principle of a graphite riser is to utilize the excellent thermal conductivity of graphite to rapidly absorb and dissipate heat during the electrofused brick casting process, preventing premature solidification of the molten metal in the riser area. Specifically, the riser system is typically located at the top or side of the mold. The molten metal enters the mold cavity through the riser, and the graphite riser helps the molten metal flow evenly and maintain a certain level of fluidity to ensure the quality of the casting. During the casting process, the molten metal flows rapidly into the mold cavity through the riser and fills the voids. Simultaneously, the graphite riser absorbs excess heat, preventing solidification defects. The riser can also expel gases and other impurities, avoiding porosity or other casting defects. However, traditional riser structures suffer from problems such as uneven molten metal flow, excessively rapid solidification, and riser blockage, leading to casting defects, low production efficiency, and affecting the quality of electrofused bricks. Therefore, a graphite riser structure for electrofused brick casting is proposed to address these issues. Utility Model Content

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a graphite riser structure for casting electrofused bricks, comprising a lower mold 1, with casting molds 4 installed on both the left and right sides of the upper part of the lower mold 1. A connecting template 3 is installed on the upper part of the casting mold 4, and an upper mold 2 is fixedly connected to the upper part of the connecting template 3. A graphite casting riser 5 is installed inside the upper mold 2, and a positioning component is fixedly connected to the lower outer side of the graphite casting riser 5. The positioning component is used to securely install the graphite casting riser 5 on the upper mold 2. A flow channel 12 is provided in the middle of the interior of the connecting template 3 and the casting mold 4 to guide the flow. The flow channel 12 is connected to the graphite casting riser 5, allowing the melt to enter the casting mold 4. Four upper support holes 13 are provided around the outer perimeter of the flow channel 12. The flow channel 12 on the casting mold 4 is provided with flow distribution chambers 16 on both the left and right sides. The outlet of the flow distribution chamber 16 is provided with an injection chamber 17. The lower side of the inside of the casting mold 4 is provided with forming chambers 18 on the left and right sides. The upper side of the inside of the casting mold 4 is provided with flow distribution components. The flow distribution components are used to allow the melt to quickly flow into the forming chamber 18. Through the multiple flow distribution and injection of the melt, the melt is prevented from solidifying in the riser.

[0032] The flow distribution assembly includes a discharge channel 14, which is located on the upper side of the casting mold 4. A lower support hole 15 is provided on the side of the discharge channel 14 away from the mold. Both the discharge channel 14 and the lower support hole 15 are connected to the molding cavity 18. The upper support hole 13 is connected to the discharge channel 14.

[0033] The molten metal is injected into the casting mold 4 through the graphite casting riser 5. After entering the graphite casting riser 5, the molten metal flows sequentially into the guide channels 12 opened in the connecting template 3 and the casting mold 4. Then, through the diversion cavity 16, the molten metal is injected into the forming cavities 18 on both sides. While the molten metal enters the guide channel 12 on the connecting template 3, it is diverted into the interior of the discharge channel 14 through the upper support hole 13. Subsequently, the molten metal is injected into the forming cavity 18. At the same time as the molten metal enters the discharge channel 14, it is diverted again into the forming cavity 18 through the lower support hole 15. This achieves the goal of increasing the number of casting channels to enable the molten metal to enter the forming cavity 18 quickly, preventing the molten metal from solidifying too early in the riser area and causing riser blockage.

[0034] Reference Figures 3-5 The positioning component includes a locking block 9, which is fixedly connected to the lower outer side of the graphite casting riser 5. A fixing hole 10 is provided inside one side of the locking block 9. A locking groove 7 is provided inside the upper mold 2 at the same position as the locking block 9. The locking block 9 is slidably connected inside the locking groove 7. An arc-shaped groove 8 is provided on the lower side of the locking block 9. An elastic element 11 is fixedly connected to the inner wall of one side of the arc-shaped groove 8. The elastic element 11 is slidably connected inside the fixing hole 10. The graphite casting riser 5 is fixedly connected to the inside of the upper mold 2 by fixing bolts 6. The locking block 9 is slidably connected inside the arc-shaped groove 8.

[0035] By aligning the locking blocks 9 on both sides of the graphite casting riser 5 with the slots 7 opened on the upper mold 2, the graphite casting riser 5 is then inserted into the upper mold 2. The riser is then rotated to the left, causing the locking blocks 9 to slide inside the arc-shaped groove 8 until they abut against the inner wall of the arc-shaped groove 8. Simultaneously, the elastic element 11 is inserted into the fixing hole 10, thus positioning and installing the graphite casting riser 5. Then, using external tools, the fixing bolts 6 are rotated and screwed into the graphite casting riser 5 into the upper mold 2, completing the fastening installation of the riser. Because the slots 7 and the arc-shaped groove 8 are L-shaped as a whole, even if some of the fixing bolts 6 become loose, the stability of the riser is still ensured. This achieves double installation of the graphite casting riser 5, ensuring its stability and improving the reliability and safety of the entire device.

[0036] Reference Figure 1 Cylinders 19 are installed at the four corners of the lower mold 1, and connecting sleeves 20 are fixedly connected at the four corners of the upper mold 2. The output end of the cylinder 19 is fixedly connected to the connecting sleeve 20. The lower mold 1, upper mold 2, connecting template 3 and casting mold 4 are all connected by bolts.

[0037] After the electrofused brick cools and solidifies, the cylinder 19 is activated, which, under the action of the connecting sleeve 20, moves the upper mold 2 and the connecting template 3, separating them from the casting mold 4. This allows the two casting molds 4 to be disassembled and the electrofused brick to be removed. The lower mold 1, upper mold 2, connecting template 3, and casting mold 4 are connected to each other by bolts, ensuring that the mold can be disassembled when maintenance or replacement of individual parts of the structure is required, thus extending the service life of the mold.

[0038] Working principle: When the device is needed, the melt is injected through the graphite casting riser 5, and then flows into the guide channel 12 in the connecting template 3 and the casting mold 4 in sequence. Then, the melt is injected into the two side forming cavities 18 through the diversion cavity 16. At the same time, when the melt enters the guide channel 12 on the connecting template 3, it is diverted into the discharge channel 14 through the upper support hole 13, and then injected into the forming cavity 18. When the melt enters the discharge channel 14, it is diverted again into the forming cavity 18 through the lower support hole 15, thus completing the rapid casting of the melt.

[0039] By aligning the two side blocks 9 of the graphite casting riser 5 with the slots 7 of the upper mold 2, and then rotating it to the left, the blocks 9 slide into the arc groove 8 and abut against the inner wall. At the same time, the elastic element 11 is inserted into the fixing hole 10 to position the riser. Then, the fixing bolts 6 are screwed into the graphite casting riser 5 into the upper mold 2 and tightened by external tools. Because the slots 7 and the arc groove 8 are L-shaped, even if some of the fixing bolts 6 are loose, the stability of the riser can be ensured.
