[0022] The automatic titanium alloy sand casting line provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0023] This application discloses an automated line for titanium alloy sand casting. For example... Figure 1 and Figure 2 As shown, the automatic titanium alloy sand casting line includes multiple hoppers 3, a sand mixer 7, a vibrating table 9, a leveling station 10, and a flipping and mold-removing machine 11.

[0024] Each hopper 3 has a first inlet at its top and a first outlet at its bottom, with the first outlet connected to a feeding device 4; the sand mixer 7 has a second inlet at its top and a second outlet on one side near its bottom, with each feeding device 4 leading to the second inlet.

[0025] The top of the compaction table 9 is used to place the sand box 8, and the sand box 8 is placed below the second outlet; the leveling station 10 and the flipping mold taking machine 11 are arranged sequentially on one side of the compaction table 9. The leveling station 10 is used to level the sand box 8, and the flipping mold taking machine 11 is used to flip the sand box 8; the compaction table 9, the leveling station 10 and the flipping mold taking machine 11 are connected by roller conveyors.

[0026] By using the automatic titanium alloy sand casting line in this technical solution, the number of hoppers 3 is configured according to the composition of the sand mold, and each material is placed in the corresponding hopper 3. During titanium alloy sand casting, the material in the hopper 3 is transported to the sand mixer 7 through the feeding device 4 according to the sand mold composition ratio. Liquid adhesive is added to the sand mixer 7 through the second inlet. The sand mixer 7 works synchronously to mix the solid and liquid evenly. Then, the mixed sand is automatically filled into the sand box 8 located on the vibrating table 9 through the second outlet. After the vibration compaction table 9 is started, the loose sand is compacted to the molding strength of the mold. Then, the roller conveyor drives the sand box 8 to the scraping station 10 to scrape the floating sand on the upper surface of the mold. Then, the sand box 8 enters the flipping mold release machine 11. An upper cover plate is added to the sand box 8. The flipping mold release machine directly clamps the sand box 8 to complete the flipping action, reducing the manual mold locking process. The mold is released after micro-vibration, which is safe and reliable. The flipping is stable, the mold does not shift, the molding quality is good, and the mold completion time is greatly reduced. This effectively improves the production capacity of titanium alloy sand molds, increases efficiency, and stabilizes product quality.

[0027] In this invention, the compaction table 9 compacts the sand mold, resulting in uniform overall strength. This reduces mold cracking during drying and high / low temperature processes, improves yield, and reduces unnecessary mold or casting repairs, thereby lowering production costs. The use of the flipping and demolding machine 11 solves the problem of sand box 8 being prone to impact, vibration, and slippage during flipping due to its large size and weight. The demolding is quick and stable, avoiding the risk of serious dimensional deviations and mold breakage caused by manually knocking the mold from side to side, which could lead to separation of the molding sand from the inner wall of the sand box 8, followed by shaking and removing loose pieces.

[0028] In this invention, the number of silos 3 can be two, three, four or five, depending on the composition of the sand mold. Specifically, this invention has three silos 3, which respectively hold three solid materials: bauxite sand, bauxite powder and cement. Furthermore, the capacity of the silos 3 can be reasonably designed according to the daily output of the sand mold.

[0029] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the automatic titanium alloy sand casting line also includes a level gauge 5, which is located above the sand mixer 7. The level gauge 5 has a third inlet at the top and a third outlet at the bottom. The third outlet leads to the second inlet, and each feeding device 4 leads to the third inlet.

[0030] The material is weighed by the level gauge 5 and then transported to the sand mixer 7, which makes the addition of material more precise and further improves the molding quality of the sand mold.

[0031] In some embodiments of this utility model, such as Figure 1 As shown, the automatic titanium alloy sand casting line also includes a liquid adhesive electronic scale 6, which is located above the sand mixer 7 and is used to weigh the liquid adhesive and convey it to the second inlet.

[0032] The liquid adhesive is weighed by the liquid adhesive electronic scale 6 and then transported to the sand mixer 7. This allows for more precise addition of the liquid adhesive and better adhesion of the solid materials, thereby further improving the molding quality of the sand mold.

[0033] In some embodiments of this utility model, such as Figure 1 As shown, the automatic titanium alloy sand casting line also includes a hoist 2, which is located on one side of the silo 3. The hoist 2 has a feeding port 1 near its bottom and a discharge port at its top for conveying materials to each silo 3.

[0034] The elevator 2 can conveniently and quickly add materials to the silo 3 located at a high position, reducing labor intensity and improving efficiency.

[0035] In this utility model, a hoist 2 can be set for each silo 3, or a hoist 2 can be set for all silos 3. The discharge port can be set to be movable and steerable, so that the corresponding material can be added to each silo 3.

[0036] In some embodiments of this utility model, such as Figure 1 As shown, the automatic titanium alloy sand casting line also includes a transfer car 12, which is located on the side of the flipping mold take-up machine 11 away from the leveling station 10.

[0037] Furthermore, the transfer vehicle 12 is an automated guided vehicle (AGV). Through the transfer vehicle 12, especially the automated guided vehicle, the formed titanium alloy sand mold can be transferred in a timely and effective manner, further improving work efficiency.

[0038] Furthermore, the top of the transfer vehicle 12 is equipped with roller conveyors. The roller conveyors on the transfer vehicle 12 and the roller conveyors on the flipping mold take-up machine 11 can work together well, which makes it convenient for the transfer vehicle 12 to receive the sand mold from the flipping mold take-up machine 11, and also makes it convenient for the transfer vehicle 12 to move the sand mold to the natural drying area.

[0039] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the feeding device 4 is a screw feeder, which can more controllably convey solid materials to the sand mixer 7.

[0040] In some embodiments of this utility model, the automatic titanium alloy sand casting line also includes a robot (not shown), which is located on one side of the leveling station 10, and the movable end of the robot is connected to a scraper.

[0041] By using a robotic arm to control the scraper, the loose sand on the upper surface of the sand box 8 is scraped flat, which is more efficient and consistent than manual scraping.

[0042] In some embodiments of this utility model, the automatic titanium alloy sand casting line also includes a dust removal system (not shown), which is used to adsorb dust particles during the titanium alloy sand casting process.

[0043] In this utility model, the dust removal system has a dust adsorption chamber, a gas inlet, and a gas outlet. Multiple gas inlets can be set up and are respectively located near the feeding port 1, the silo 3, the level gauge 5, the sand mixer 7, the vibrating table 9, the leveling station 10, and the flipping mold removal machine 11, so as to adsorb dust particles in the production process in a timely manner, reduce pollution, and improve the comfort of the working environment.

[0044] In some embodiments of this utility model, the outlets of the sand mixer 7, the level gauge 5, etc., can be controlled by a pneumatic gate.

[0045] In some embodiments of this utility model, the automatic titanium alloy sand casting line also includes an electrical control system and a pneumatic control system. The electrical control system can realize the automated process control of the automatic titanium alloy sand casting line, and the pneumatic control system can realize the removal of the auxiliary sand box 8 movable blocks.

[0046] In some embodiments of this utility model, the elevator 2, silo 3, level gauge 5, and sand mixer 7 can be arranged in layers in the production workshop by means of frame erection.
