[0001] The utility model relates to the technical field of vibration devices, in particular to a lifting sand mold vibration blanking platform. Background Technique

[0002] The lost foam casting process is to bury a paraffin or foam model similar to the size of the casting into dry sand (quartz sand) for vibration molding after brushing and drying with refractory coating. The lost mold casting three-dimensional vibration platform is used to make the dry sand generate dynamic flow in the sand box, improve the filling property and density of the dry sand, and prevent casting defects. After the vibration process is completed, the model is poured under negative pressure, so that the high-temperature liquid metal occupies the position of the model.

[0003] In the prior art, the platform for sand mold sand injection often adopts the flat sand injection method, that is, the lost foam sand box is exposed at the working station of the sand injection platform, and with the vibration of the platform, the purpose of tightly filling the dry sand into the lost foam sand box is achieved. Due to the lack of a corresponding sand recovery structure, the sand that fails to enter the inside of the lost foam sand box scatters everywhere after the vibration molding is completed, causing inconvenience to the subsequent recovery.

[0004] For this reason, a lifting sand mold vibration blanking platform is proposed, which has the advantages of convenient sand recovery and the loading and unloading of the lost foam sand box, thereby solving the problems in the above background technique. Content of the Utility Model

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, by starting the vacuum feeder, the suction pipe of the vacuum feeder sucks the dry sand stored at the sand return cavity, and then the sand injection head of the discharge pipe of the vacuum feeder injects the dry sand into the lost foam sand box arranged on the vibrating table, and the dry sand is wrapped around the periphery of the lost foam sand box. By starting the vibration motor installed inside the vibrating table and combining several groups of rubber frames and springs arranged at the bottom of the vibrating table, the vibration of the vibration motor acts on the lost foam sand box in the receiving groove to realize the compaction of the lost foam sand box. After the compaction, the dry sand passes through the hollow net between the support box and the sand return base and flows back into the sand return cavity, achieving the purpose of convenient dry sand recovery. By the external winding device to wind and unwind the lifting rope, the wire rope connected by the hook and the lifting rope is used to lift or lower the vibrating table, so that the vibrating table can be stably lifted and lowered under the guiding action of several guide rods in the support box, providing convenience for the feeding and discharging of the lost foam sand box.

In order to facilitate the recovery of dry sand, a slope surface is provided at the bottom of the sand return cavity 7;

[0023] In one embodiment, a through hole 10 is provided on the upper surface of the support box 1, and a guide sleeve 11 is welded on the inner side surface of the through hole 10. A hand-held rod 13 is fixedly connected to the sand injection head 14, and one end of the hand-held rod 13 is inserted and connected with the guide sleeve 11 in the through hole 10. The telescopic hose 9 is inserted through the through hole 10. By horizontally pushing the hand-held rod 13, since the guide sleeve 11 in the through hole 10 is sleeved with the hand-held rod 13, the hand-held rod 13 can drive the sand injection head 14 to smoothly move horizontally from left to right. Furthermore, the telescopic hose 9 provided on the discharge pipe of the vacuum suction feeder 8 extends adaptively following the movement of the hand-held rod 13, so that the sand injection position of the sand injection head 14 extends above the vibrating table 3.
