Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology for machine bases, specifically to a lost foam casting forming device for machine bases. Background Technology

[0002] Lost foam casting is a new casting method that involves bonding foam models of the same size and shape as the casting into a model cluster, applying refractory coating and drying it, then embedding it in dry sand for vibration molding, and casting under vacuum negative pressure. This causes the model to vaporize, the liquid metal to occupy the model's position, and after solidification and cooling, the casting is formed. It is currently the greenest and most environmentally friendly casting process in the casting industry.

[0003] For example, a lost foam casting mold for a motor base, with announcement number CN208628376U, includes a mold shell, a positioning rod pre-drilled hole, a steam pipe pre-drilled hole, a spray pipe pre-drilled hole, a drain pipe pre-drilled hole, a hydraulic cylinder pre-drilled hole, an upper template, an upper mold core, a lower template, a lower mold core, movable tiles, modules, module sealing plates, a steam inlet pipe, a spray pipe, a drain pipe, a positioning rod, and a hydraulic cylinder. This device solves the problem that in the traditional mold-making process, the entry and exit of the mold from the steam cylinder, the opening and closing of the mold, and the removal of the foam model are all done manually.

[0004] Most of the aforementioned existing technologies improve the overall structure. However, while existing lost foam casting molding devices solve the problem of manual loading and unloading in the traditional process, they are inconvenient to adjust the mold in actual use. Furthermore, the four clamping plates are driven by four power sources to converge in the middle to form the mold, which means that the four power sources need to be adjusted every time it is used. This is not only cumbersome, but also inconvenient to synchronize the pushing force of the four push plates. Moreover, the size of the mold cannot be adjusted according to the machine base, which limits its use. Utility Model Content

[0005] The purpose of this utility model is to provide a lost foam casting molding device for machine bases, so as to solve the problems mentioned in the background art that the existing lost foam casting molding devices for machine bases are inconvenient to adjust the mold size during use, and the mold driving force is relatively dispersed and difficult to be uniformly adjusted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lost foam casting molding device for a base, comprising a fixed base, a limiting support assembly disposed above the fixed base, a spray-type capping assembly slidably mounted above the limiting support assembly, and a rotating shrinking assembly slidably mounted inside the limiting support assembly; the rotating shrinking assembly includes a servo motor, and through the internal structure of the rotating shrinking assembly in conjunction with the internal structure of the limiting support assembly, the device can be ensured to shrink synchronously while easily adapting to molds of different sizes; the spray-type capping assembly includes a bracket, and through the internal structure of the spray-type capping assembly, the material being formed inside the mold can be rapidly cooled.

[0007] Furthermore, the limiting support assembly includes a support column, which is fixedly installed above the fixed base. A processing table is fixedly installed above the support column, and the processing table has four reserved slots inside.

[0008] Furthermore, a limiting frame is fixedly installed on the side end of the fixed base, a threaded rotating rod is rotatably installed inside the limiting frame, and a drive shaft is fixedly installed above the threaded rotating rod.

[0009] Furthermore, a collar is fixedly installed on the side end of the bracket, and the bracket is slidably installed above the support column through the collar and the threaded rotating rod.

[0010] Furthermore, a top cover is fixedly installed below the bracket, a nozzle is fixedly installed inside the top cover, and a water pump is fixedly installed above the nozzle.

[0011] Furthermore, a connecting pipe is fixedly installed above the bracket, and the connecting pipe is connected to the inside of the water pump.

[0012] Furthermore, a servo motor is fixedly installed above the fixed base, and a rotating disk is rotatably installed below the processing table. The lower part of the rotating disk is connected to the upper output shaft of the servo motor via a spline.

[0013] Furthermore, four connecting bolts are rotatably mounted on the outer surface of the rotating disk, and a fixing rod is sleeved on the outer surface of each connecting bolt. A limiting block is rotatably sleeved on the side end of each fixing rod away from the connecting bolt.

[0014] Furthermore, each of the limiting blocks is slidably installed inside the reserved slot, an extension rod is fixedly installed on the side end of each of the limiting blocks, a mold plate is slidably installed on the side end of each of the extension rods, a spring is fixedly installed on the side end of each of the mold plates, a spring is provided inside each of the mold plates, and the side end of each of the extension rods is slidably installed inside the mounting frame, wherein one side of the spring is connected to the side end of the extension rod, and the other side is connected to the inner wall of the mounting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This lost foam casting molding device uses a servo motor to drive a rotating disk to rotate, which in turn pulls a fixed rod to slide. When the fixed rod slides, it can pull a limit block to move in a specified direction within the processing table. This, in conjunction with the extension rod and mounting frame, pushes the mold plate towards the center of the processing table. Then, the four mold plates push each other to adjust the extension rod to slide within the mounting frame. This allows the device to adjust the mold size as needed during use, while ensuring that the molds are driven by the same power source, thus facilitating mold adjustment and use. Furthermore, by connecting a water supply pipe above the connecting pipe, a water pump is used to draw water from the outside, and then a nozzle connected below the water pump is used to spray the water onto the molded material. This allows the device to accelerate the cooling of the molded material during use, thereby improving the device's efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1 - Figure 6 A lost foam casting molding device for machine bases is disclosed to address the problem that existing lost foam casting molding devices often lack the convenience of adjusting the mold size according to the machine base dimensions. The device includes a fixed base 4, a limiting support assembly 1 mounted above the fixed base 4, a spray-type capping assembly 2 slidably mounted above the limiting support assembly 1, and a rotating shrinking assembly 3 slidably mounted inside the limiting support assembly 1. The rotating shrinking assembly 3 includes a servo motor 31, and its internal structure cooperates with the internal structure of the limiting support assembly 1. The structure ensures that the device can shrink synchronously while easily adapting to molds of different sizes; the spray-type capping assembly 2 includes a bracket 21, and the internal structure of the spray-type capping assembly 2 can quickly cool the material being formed in the mold; the limiting support assembly 1 includes a support column 11, which is fixedly installed above the fixed base 4; a processing table 12 is fixedly installed above the support column 11; the processing table 12 has four reserved slots 13 inside; a limiting frame 14 is fixedly installed on the side end of the fixed base 4; and a threaded rotating part is rotatably installed inside the limiting frame 14. A drive shaft 16 is fixedly installed above the threaded rotating rod 15. A collar 22 is fixedly installed on the side end of the bracket 21. The bracket 21 is slidably installed above the support column 11 through the collar 22 and the threaded rotating rod 15. A servo motor 31 is fixedly installed above the fixed base 4. A rotating disk 32 is rotatably installed below the processing table 12. The lower part of the rotating disk 32 is connected to the upper output shaft of the servo motor 31 through a spline. Four connecting bolts 33 are rotatably installed on the outer surface of the rotating disk 32. A fixing rod 34 is sleeved on the outer surface of each connecting bolt 33, away from the connecting bolt 33. Each fixed rod 34 on one side is rotatably fitted with a limiting block 35. Each limiting block 35 is slidably installed inside the reserved groove 13. Each limiting block 35 is fixedly installed with an extension rod 36 on its side. Each extension rod 36 is slidably installed with a mold plate 37 on its side. Each mold plate 37 is fixedly installed with a spring 39 on its side. Each mold plate 37 is provided with a spring 39 inside its interior. Each extension rod 36 is slidably installed inside the mounting frame 38. One side of the spring 39 is connected to the side of the extension rod 36, and the other side is connected to the inner wall of the mounting frame 38.

[0020] like Figure 1 - Figure 6 As shown, the user starts the servo motor 31. The servo motor 31 drives the upper rotating disk 32 to rotate via the output shaft, which in turn drives the connecting bolt 33 to rotate and pulls the fixing rod 34 to move. When the fixing rod 34 moves, it can cooperate with the limit of the reserved slot 13, so that the limit block 35 slides in a straight line during the movement. When the limit block 35 slides, its side extension rod 36 will push the mold plate 37 to move. When the four mold plates 37 move towards the middle position of the processing table 12 at the same time, the side ends of each mold plate 37 are in contact with each other. Since the left and right sides of each mold plate 37 are of different lengths, This causes each closely attached mold plate 37 to push against each other, causing one side of the extension rod 36 to slide within the mounting frame 38, thereby compressing the spring 39. At this time, the gap enclosed by the four mold plates 37 will be adjusted by the distance of each limiting block 35 sliding, so that the device can be quickly adjusted according to the size of the casting base, thus facilitating the casting operation. At the same time, each mold plate 37 is driven by the same servo motor 31, so the driving force on each group is the same, making it easier for the user to control and adjust the device.

[0021] Example 2: Figure 1 - Figure 3 The technical solution shown, based on Embodiment 1, in order to solve the problem that the material cools down slowly after processing in the existing lost foam casting molding device, also discloses: a top cover 24 is fixedly installed below the support 21, a nozzle 25 is fixedly installed inside the top cover 24, a water pump 26 is fixedly installed above the nozzle 25, and a connecting pipe 23 is fixedly installed above the support 21, and the connecting pipe 23 is connected to the inside of the water pump 26.

[0022] like Figure 1 - Figure 3 As shown, the user connects a power source above the drive shaft 16, which drives the drive shaft 16 to rotate, thereby driving the threaded rotating rod 15 to rotate. With the help of the limiting frame 14, the user can limit the rotation and push the collar 22 to adjust the height. When the collar 22 is pushed down, it can push the bracket 21 down, which in turn can work with the top cover 24 at the bottom of the bracket 21 to seal the top of the mold. After casting is completed, the user connects a water supply pipe along the connecting pipe 23 and then starts the water pump 26. The water pump 26 works with the water supply pipe to draw water, and then the nozzle 25 sprays the water into the mold below, thereby rapidly cooling the material formed in the mold. This improves the cooling efficiency of the finished product and thus improves the efficiency of the device.
