Description

Technical Field

[0001] The utility model relates to the technical field of metal parts casting, in particular to a vacuum suction casting device used for casting processing. Background Art

[0002] With the rapid development of the foundry industry, the demand for the metal casting industry has also increased. The workers melt the metal into a liquid state, then pour the liquid into the casting mold for cooling and molding, and then grind it into metal parts. Among them, the "A metal casting mold cooling device" disclosed by the authorization number "CN217666345U" has solved the problem that the cooling effect of the existing metal casting mold is relatively poor. A large amount of cooling water is filled in during use, which easily causes the vibration of the mold and affects the use of the mold. The top punch of the device lacks a cooling structure, resulting in uneven cooling of the device, affecting the quality of the casting. The device lacks a demoulding structure, which affects the removal of the casting. After further searching, it was found that the "A metal casting surface cooling device" disclosed by the authorization number "CN217317516U" The "surface polishing device" effectively solves the problem that the existing castings need to be polished after casting to improve the glossiness of the casting surface through a specific technical structure setting. When polishing the tubular metal castings, they need to be clamped. However, the existing pipe clamping device is single, and it is troublesome to clamp metal pipes of different diameters. However, in actual use, a vacuum suction casting device with a similar structure for casting processing still has many defects, such as: most of the existing metal castings are manually taken out of the molten metal from the furnace for casting, which is inconvenient for the staff to operate, and the casting process is manually operated, resulting in the situation that the molten metal is splashed during casting, which is easy to be dangerous, so it is necessary to design a vacuum suction casting device for casting processing. Utility Model Content

[0003] The purpose of the utility model is to provide a vacuum suction casting device for casting processing to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum suction casting device for casting processing, comprising a working platform, an incinerator, a smelting furnace, a liquid suction metal tube and a casting mold, a vacuum pump is fixedly installed on the top of the working platform, a liquid suction metal tube is fixedly connected between the liquid suction metal tube and the smelting furnace, a liquid suction metal delivery pipe is fixedly installed on one side of the vacuum pump, a casting nozzle is fixedly connected to the bottom of the liquid suction metal delivery pipe, a bracket is fixedly installed on one side of the top of the working platform, the casting nozzle passes through the bracket, a connecting rod is evenly fixedly installed on the bottom of the bracket, a support ring is fixedly connected to the bottom of the connecting rod, and a casting funnel is movably installed inside the support ring.

[0005] First, the metal inside the smelting furnace is melted by incineration inside the incinerator. Then the staff places the casting mold under the casting nozzle. The vacuum pump pours the liquid metal into the inside of the casting funnel through the liquid suction metal tube and the liquid suction metal delivery tube. The liquid metal sprayed from the casting nozzle is gathered and then flows into the casting mold through the casting funnel for casting. This avoids the splashing of liquid metal during the casting process and improves the casting efficiency of the device.

[0006] Preferably, a slide groove is provided at the front and rear ends of one side of the working platform, a slide rod is slidably installed inside the slide groove, and a clamping plate is fixedly installed on the top of the slide rod. When the casting mold is placed on the top of the working platform, the slide rod slides inside the slide groove, so that the clamping plate clamps and fixes the casting mold, thereby preventing the casting mold from being displaced during the casting process and causing the metal liquid to splash, thereby improving the casting stability of the device.

[0007] Preferably, the front and rear ends of the bottom of the working platform are fixedly installed with fixing plates, a screw is rotatably installed between the fixing plates, a threaded ring fixed to the bottom of the slide rod is movably installed on the outer side of the screw through a thread, and a crank is fixedly installed on the front end of the screw. The staff rotates the screw through the crank to make the threaded rings move closer to each other on the outer side of the screw, thereby driving the clamping plates to move closer to each other to clamp the casting mold, thereby improving the convenience of operation of the device.

[0008] Preferably, a sealing door is rotatably installed at the opening on the other side of the incinerator, and a door handle is fixedly installed on the outside of the sealing door. The staff can open the sealing door through the door handle to add incineration fuel to the inside of the incinerator, and then seal it through the sealing door to avoid heat loss and facilitate the operation of the staff.

[0009] Preferably, a feed inlet is provided through the top of the smelting furnace, and a sealing cover is slid into the inside of the feed inlet. Metal raw materials can be added to the inside of the smelting furnace through the feed inlet, and the feed inlet is sealed by the sealing cover, thereby improving the convenience of operation of the device.

[0010] Preferably, a handle is fixedly mounted on the top of the sealing cover, and a heat-insulating sleeve is fixedly connected to the outside of the handle. The sealing cover can be opened by holding the heat-insulating sleeve and then pulling the handle upwards, and the heat-insulating sleeve protects the hands from being burned, thereby improving the protectiveness of the device.

[0011] Preferably, support legs are fixedly installed at the bottom of the working platform, and the number of the support legs is four groups. The support legs support the working platform, so that the working platform is placed more stably, and the stability of the device is improved.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up an incinerator, a smelting furnace, a vacuum pump, a liquid metal pipe, a liquid metal delivery pipe and a casting nozzle, the metal inside the smelting furnace is melted by burning inside the incinerator. Then the staff puts the casting mold under the casting nozzle. The vacuum pump pours the metal liquid into the casting mold through the liquid metal pipe and the liquid metal delivery pipe, replacing manual casting and improving the casting efficiency of the device.

[0014] 2. A bracket, a connecting rod, a support ring and a casting funnel are provided. The connecting rod fixes the support ring at the bottom of the casting nozzle. The casting funnel is placed inside the support ring. Then, the molten metal is cast inside the casting funnel through the casting nozzle. The molten metal sprayed from the casting nozzle is gathered and then flows into the casting mold through the casting funnel for casting. This avoids the spillage of the molten metal during the casting process and reduces safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
