Description

Technical Field

[0001] The utility model relates to a sand casting bottom plate, in particular to a sand casting bottom plate conversion device, belonging to the technical field of sand casting equipment. Background Art

[0002] Sand casting is a common metal casting process that uses sand molds as casting molds. In this process, a sand mold is first made according to the shape of the part to be cast. It is usually made of a special mixture of sand and a binder. The sand mold is then split into two halves to form a cavity to facilitate the injection of metal.

[0003] The sand casting base plate is one of the important parts used to support the sand mold. During the sand casting process, when making the sand mold, a base plate is usually placed at the bottom to provide support and stability for the mold. This base plate can be made of metal, wood or other materials, and the specific choice depends on the size and weight of the casting and the requirements of the production process.

[0004] The size of the sand casting bottom plate is not easy to adjust. If you need to increase the support area of ​​the mold or change the structure of the mold, you need to replace the sand casting bottom plate. At the same time, you also need to fix the sand mold well to prevent the sand mold from displacement or deformation during the casting process. For this reason, we provide a sand casting bottom plate conversion device. Utility Model Content

[0028] The utility model embodiment provides a sand casting bottom plate conversion device.

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a base plate 1, a plurality of telescopic mechanisms 2 are arranged on the side of the base plate 1, the telescopic mechanism 2 includes a screw rod 201 rotatably connected to the side of the base plate 1, a bearing 206 is installed on the side of the base plate 1, the screw rod 201 is rotatably connected to the base plate 1 through the bearing 206, the bearing 206 is arranged to make the screw rod 201 rotate more stably, the bearing 206 can support the screw rod 201, so that the screw rod 201 can rotate more easily, a slider 202 is threadedly connected to the side of the screw rod 201, the telescopic mechanism 2 also includes an extension plate 203, a through hole 207 is opened on the extension plate 203, the slider 202 is fixed in the through hole 207, and the through hole 207 does not contact the side of the screw rod 201.

[0030] The extension plate 203 is limited by the guide rod 204. Therefore, the rotation of the screw rod 201 will drive the slider 202 and the extension plate 203 to move along the length direction of the screw rod 201, thereby adjusting the relative distance between the base plate 1 and the extension plate 203, thereby adjusting the size of the device. When it is necessary to increase the support area of ​​the mold or change the structure of the mold, the distance between the extension plate 203 and the base plate 1 is adjusted according to the required size, so that there is no need to replace the sand casting base plate, which is convenient to use.

[0031] Two symmetrical guide rods 204 are fixed to the side of the base plate 1, and a hole is opened on the extension plate 203 for sliding contact with the guide rod 204. The guide rod 204 is connected to the extension plate 203 through the hole. A knob 205 is fixed to the end of the screw rod 201 away from the base plate 1, and the outer contour of the knob 205 is cylindrical.

[0032] During the movement of the extension plate 203, the guide rod 204 will also slide in the hole opened on the extension plate 203. The extension plate 203 is limited by the guide rod 204, which makes the movement of the extension plate 203 more stable. The knob 205 is convenient for adjusting the screw rod 201, providing a reasonable force point.

[0033] See also Figure 2 and Figure 3 A fixing component 3 for clamping the sand mold is provided on the telescopic mechanism 2. The fixing component 3 includes a fixing plate 301 fixed on the top surface of the extension plate 203. A threaded block 302 penetrating the fixing plate 301 is fixed on the side of the fixing plate 301. The threaded block 302 is internally threadedly connected to a threaded rod 303. The end of the threaded rod 303 close to the bottom plate 1 is rotatably connected to a clamping plate 306. A rubber pad 307 is fixed to a side of the clamping plate 306 close to the bottom plate 1. The outer contour of the rubber pad 307 is square. The provision of the rubber pad 307 can protect the sand mold and prevent the clamping plate 306 from causing damage to the sand mold, thereby further improving the fixing effect of the sand mold.

[0034] The rotation of the threaded rod 303 will cause the threaded rod 303 to rotate in and out of the threaded block 302. The moving threaded rod 303 will drive the clamping plate 306 rotatably connected thereto to move. Since the clamping plate 306 is limited by the support rod 304, the clamping plate 306 will move horizontally driven by the threaded rod 303 without rotating. At the same time, under the limitation of the support rod 304, the clamping plate 306 will move more stably. The sand mold can be fixed by the clamping plate 306 to prevent the sand mold from displacement or deformation during the casting process.

[0035] Two symmetrical support rods 304 are fixed to the side of the splint 306. A hole that is in sliding contact with the support rod 304 is opened on the fixing plate 301. The support rod 304 is connected to the fixing plate 301 through the hole. A rotating rod 305 is fixed to the end of the threaded rod 303 away from the base plate 1. The outer contour of the rotating rod 305 is cylindrical, and the threaded rod 303 can be easily rotated through the rotating rod 305.

[0036] Working principle: When it is necessary to increase the support area of ​​the mold or change the structure of the mold, the screw rod 201 is rotated by the knob 205. The rotation of the screw rod 201 will drive the slider 202 and the extension plate 203 to move along the length direction of the screw rod 201, thereby adjusting the relative distance between the base plate 1 and the extension plate 203, thereby adjusting the size of the device without replacing the sand casting base plate.

[0037] After the adjustment is completed, the threaded rod 303 is rotated by the rotating rod 305. The rotation of the threaded rod 303 will cause the threaded rod 303 to rotate in and out of the threaded block 302. The moving threaded rod 303 will drive the splint 306 rotatably connected thereto to move. Under the limitation of the support rod 304, the splint 306 will move more stably. The sand mold can be fixed by the splint 306, thereby preventing the sand mold from being displaced or deformed during the casting process.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
