Description

Technical Field

[0001] The utility model belongs to the technical field of lost foam castings, in particular to a pouring device for lost foam castings. Background Art

[0002] Lost foam casting (also known as full-mold casting) is a new casting method in which wax or foam models with similar size and shape to the casting are bonded together into a model cluster, coated with refractory paint and dried, buried in dry quartz sand for vibration molding, and poured under negative pressure to vaporize the model, so that liquid metal occupies the position of the model and forms a casting after solidification and cooling.

[0003] A pouring device for lost foam castings with a publication number of CN216263338U specifically discloses: pouring molten metal, after forming, loosening the locking screw to disengage from the top surface of the connecting ring, and then holding the handle to drag the sleeve to drive the surrounding tube to be pulled out from the connecting ring. In lost foam casting, it is necessary to fill the inside of the cylinder with sand, and after casting and forming, the sand needs to be poured out and refilled. When taking out the surrounding tube, it needs to be pulled out manually, but because the surrounding tube is deeply buried in the sand, it is inevitable that the staff will pull out the surrounding tube quickly and easily, which leads to a decrease in the pouring efficiency of lost foam castings, thereby greatly reducing the scope of application of the pouring device.

[0029] The bearing bin 7 is fixed at the central position of the upper end surface of the bearing plate 6. The inner wall of the bearing bin 7 is provided with an inclined slope 1 701 and an inclined slope 2 702, and the diameter of the inclined slope 2 702 is smaller than the inclined slope 1 701. The lower end surface of the bearing bin 7 is provided with a sand discharge port 703, and the cross section of the sand discharge port 703 is an inverted trapezoidal structure. The bearing bin 7 is provided with the inclined slope 1 701 and the inclined slope 2 702, which can prevent sand from getting stuck on the inner wall of the bearing bin 7 and affecting subsequent processing. The upper end surface of the support plate 2 is provided with a collecting bin body 14, and the collecting bin body 14 and the sand discharge port 703 maintain the same vertical center line.
