[0002] Lost foam casting is one of the most commonly used casting methods today. EPS foam is commonly used to create the model for the casting. After mold inspection, coating, and drying, the casting is then produced through processes such as molding, pouring, and polishing using appropriate casting techniques. During the baking process of lost foam castings, the following problems often occur, as described in the patent. See CN216173878U, which discloses a support device for transferring and drying lost foam yellow molds, belonging to the field of casting processing technology.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0017] First embodiment: like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a mechanized lost foam casting baking rack includes: a base plate 1, with a through hole 11 in the center of the base plate 1; a junction box 8 is bolted to the center of one side of the base plate 1, allowing easy connection to a power supply or other control terminal; a handheld remote control 81 is mounted above the junction box 8, enabling remote operation by the user and improving safety and convenience; a moving component located below the base plate 1, with threaded posts 2 bolted to the top of the base plate 1 near its four corners, and lifting lugs 21 bolted to the top of each threaded post 2; and a first bracket 3, adjustable and suspended above the base plate 1, with a first mounting hole 31 in the center of the first bracket 3, into which a first support plate 4 is detachably mounted, with multiple drainage holes 41 in the center of the first support plate 4 to improve airflow between the top and bottom of the first support plate 4 and to lift the castings mounted on the first support plate 4. For the baking effect, first ranging sensors 34 are bolted and installed at the four corners of the first bracket 3; the second bracket 5 is adjustable and suspended above the first bracket 3. The length of the second bracket 5 is not less than the length of the first bracket 3, and the length of the through hole 11 is not less than the length of the second bracket 5. A second mounting hole 51 is provided in the middle of the second bracket 5, and a second support plate 6 is detachably installed in the second mounting hole 51. Multiple mesh holes 61 are provided in the middle of the second support plate 6. The multiple mesh holes 61 can improve the airflow between the upper and lower parts of the second support plate 6 and connect with the leakage hole 41 on the first support plate 4, thereby improving the baking effect of the casting placed on the second support plate 6. Second ranging sensors 54 are bolted and installed at the four corners of the second bracket 5; traction adjustment components are respectively set between the first bracket 3 and the four threaded posts 2, and between the second bracket 5 and the four threaded posts 2, so as to change the suspension position of the first bracket 3 and the second bracket 5.

[0018] The movable component located below the base plate 1 allows users to easily move the base plate 1, facilitating the transfer of prepared castings to the baking chamber and the removal of baked castings, thus achieving convenient transportation. The lifting lugs 21 on the four threaded posts 2 allow for easy hoisting of the base plate 1 by a crane in the workshop. The first bracket 3 and the second bracket 5 are suspended above the base plate 1 in an adjustable manner, with a first support plate 4 and a second support plate 6 installed on them respectively. This allows the castings placed on the first support plate 4 and the second support plate 6 to be suspended above the base plate 1, achieving double-layer baking of castings, improving baking efficiency, and facilitating user adjustments based on the casting's shape and position. The center of gravity is adjusted to adapt to the baking effect of castings of various specifications and complex shapes, further optimizing the baking requirements of castings of various shapes. At the same time, during the baking process, the arrangement of the first bracket 3 and the second bracket 5 is adjusted in real time by the traction adjustment component to change the suspension state of the casting, causing the airflow around the casting to be disturbed, further accelerating the baking efficiency of the casting, so that the baking of each part of the casting achieves better results. The first distance sensor 34 and the second distance sensor 54 respectively installed under the first bracket 3 and the second bracket 5 can effectively detect the relative position between the four sides of the first bracket 3 and the two brackets 5 and the ground in real time, thereby achieving the effect of safety detection to prevent the side tipping, and further improving the safety of the baking process.

[0019] Furthermore, to facilitate user operation of the transfer base plate 1 to gradually move it in and out of the baking chamber, the moving component includes: rollers 12, which are fixedly installed around the bottom of the base plate 1 by bolts; a first gear 13 is fixedly installed on the axis of the rollers 12 by bolts; a servo motor 14 is fixedly installed on the bottom of the base plate 1 on one side of the rollers 12 by bolts; a second gear 15 is fixedly installed on the power output end of the servo motor 14 by bolts; the second gear 15 meshes with the first gear 13; the servo motor 14 drives the second gear 15 to drive the first gear 13 to rotate, so that the rollers 12 obtain rotational power, thereby realizing the movement of large castings in and out of the baking chamber, effectively reducing the user's workload in moving large castings.

[0020] Second embodiment: like Figure 2 and Figure 5As shown, the difference from the previous embodiment is that, in order to facilitate the adjustment of the suspension position of the first bracket 3 and the second bracket 5, the traction adjustment assembly includes: two mounting plates 7 that are adjustable on the periphery of the four threaded posts 2. The two mounting plates 7 located on the threaded posts 2 are respectively adapted to the first bracket 3 and the second bracket 5. A servo motor 71 is fixedly mounted on one bottom end of the mounting plate 7 by bolts. A winding drum 72 is fixedly mounted on the power output end of the servo motor 71 by bolts. A steel cable 73 is wound around the periphery of the winding drum 72. The end of the steel cable 73 away from the winding drum 72 is... Two steel cables 73, which are fixed to the top of the mounting plate 7 by bolts and located on the threaded post 2, pass through the four ends of the first bracket 3 and the two ends of the second bracket 5, respectively. By adjusting the winding amount of the steel cables 73 by the winding drum 72 through the servo motor 71, the tension of the steel cables 73 can be effectively changed to adjust the suspension position of the first bracket 3 and the second bracket 5. This allows the four ends of the first bracket 3 and the four ends of the second bracket 5 to swing or shift due to the traction of the steel cables 73. It is worth noting that the swing and shift amplitude should not be too large to prevent the risk of the casting falling.

[0021] Furthermore, to enhance the stability of the mounting plate 7 on the threaded post 2, the traction adjustment assembly further includes a connecting sleeve 75, which is fixedly installed on the top of the other side of the mounting plate 7 by bolts. The connecting sleeve 75 is sleeved around the threaded post 2. Fastening nuts 76 are threaded around the threaded post 2 at the top and bottom of the connecting sleeve 75. By changing the position of the fastening nuts 76 on the threaded post 2, the connecting sleeve 75 can be positioned on the threaded post 2, thereby adjusting the position height of each mounting plate 7 and changing the distance between the first bracket 3 and the second bracket 5, so as to achieve the effect of accommodating castings of different specifications, sizes and shapes. A positioning sleeve 74 is fixedly installed on the middle of the side of the mounting plate 7 near the connecting sleeve 75 by bolts. The positioning sleeve 74 is movably sleeved around the threaded post 2. The positioning sleeve 74 can further enhance the stability of the mounting plate 7 on the threaded post 2.

[0022] Third embodiment: like Figure 2 , Figure 3 and Figure 4As shown, the difference from the second embodiment is that a cover 35 is fixedly installed on all four sides of the upper part of the first bracket 3 by bolts. A push rod 36 is slidably inserted inside the cover 35. The length of the push rod 36 can be selected according to the size of the casting. A fastening bolt 37 is threaded into the center of the top of the cover 35. The bottom end of the fastening bolt 37 passes into the cover 35 and abuts against the push rod 36. A baffle 38 is fixedly installed on the end of the push rod 36 away from the cover 35 by bolts. A housing 55 is fixedly installed on all four sides of the upper part of the second bracket 5 by bolts. A stop bar 56 is slidably inserted into the bottom of the middle part of the housing 55. Multiple interlocking buckle assemblies are provided between the stop bar 56 and the housing 55. The buckle assembly can be composed of a raised protrusion and a collar, or it can be composed of a combination of parts that can achieve locking. The buckle assembly is used to limit the position of the stop bar 56 inside the housing 55.

[0023] The position of the baffle 38 on the first bracket 3 can be changed by adjusting the position of the push rod 36 inside the cover 35. The baffle 38 is then attached to the perimeter of the casting and the fastener 37 is tightened. This allows the casting to be positioned by the baffle 38 to prevent it from slipping off the first bracket 3, further improving the safety of the casting during the baking process. At the same time, the position of the stop bar 56 inside the housing 55 can be limited by the snap-fit ​​assembly, thereby positioning the casting on the second bracket 5 to prevent it from slipping.

[0024] Fourth embodiment: like Figure 2 , Figure 3 and Figure 4 As shown, the difference from the third embodiment is that, in order to facilitate the positioning of the first tray 4 within the first bracket 3, the first mounting hole 31 has a stepped hole structure. First slots 32 are provided around the perimeter of the first mounting hole 31. A first electromagnet 33 is fixedly installed inside the first slot 32 by bolts. The first electromagnet 33 is attracted to the first tray 4, and the attraction of the first electromagnet 33 firmly positions the first tray 4. Simultaneously, when the first electromagnet 33 is de-energized, it is easy to remove the first tray 4 from the first mounting hole 31. To facilitate the positioning of the second tray 6 within the second bracket 5, the second mounting hole 51 has a stepped hole structure. Second slots 52 are provided around the perimeter of the second mounting hole 51. A second electromagnet 53 is fixedly installed inside the second slot 52 by bolts. The second electromagnet 53 is attracted to the second tray 6. The attraction of the second electromagnet 53 can effectively position the second tray 6. At the same time, when the second electromagnet 53 is de-energized, it is easy to remove the second tray 6 from the second mounting hole 51, thus facilitating installation and replacement.

[0025] Working Principle: During use, the movable component located below the base plate 1 facilitates the movement of prepared castings in and out of the baking chamber, reducing the labor intensity of employees transferring castings. By suspending the first bracket 3 and the second bracket 5 above the base plate 1 in an adjustable manner, and installing the first support plate 4 and the second support plate 6 on the first bracket 3 and the second support plate 5 respectively, the castings placed on the first support plate 4 and the second support plate 6 can be suspended above the base plate 1. This not only achieves double-layer baking of castings, improving baking efficiency, but also allows users to adjust according to the center of gravity of the casting, achieving a baking effect suitable for castings of various specifications and complex shapes, further optimizing the baking needs of various shapes of castings. At the same time, during the baking process, the arrangement of the first bracket 3 and the second bracket 5 is adjusted in real time by the traction adjustment component, thereby changing the suspension state of the casting, causing airflow disturbance around the casting, further accelerating the baking efficiency of the casting, and achieving better baking results for all parts of the casting.
