Description

Technical Field

[0001] The utility model relates to the technical field of lost foam casting, in particular to a lost foam casting device. Background Art

[0002] Lost foam casting is a new casting method that combines paraffin or foam models of similar size and shape to the casting into a model cluster, brushes refractory coating and dries it, buries it in dry quartz sand for vibration molding, and then pours it under negative pressure to vaporize the model, allowing liquid metal to occupy the model position and form a casting after solidification and cooling.

[0003] After searching, for example, a lost foam casting device provided by Chinese utility model patent CN215199553U, although the device allows hot air to circulate inside the insulation box by setting an induced draft hood and a guide pipe, thereby improving the drying efficiency of the lost foam, but because the lost foam is in a stationary state in the insulation box, the side of the lost foam body close to the exhaust fan and the guide pipe will inevitably be heated more, while the other sides are heated less, resulting in uneven heating of the lost foam, which may affect the subsequent process, and the heat will also be lost to a certain extent during the transmission through the guide pipe, affecting the drying efficiency, so a lost foam casting device is proposed to solve the above problems.

[0006] The drying structure includes a driving motor, which is fixedly mounted on the rear wall of the heating box, a cam is fixedly mounted on the output end of the driving motor, a spring is fixedly mounted on the top wall of the heating box, a movable plate is fixedly connected to the bottom end of the spring, a vertical plate is fixedly mounted on the right side of the movable plate, five air blades are hinged on the right side of the vertical plate, and a heating wire is fixedly mounted between the front and rear side walls of the heating box;

[0007] The rotating assembly includes a rotating motor, which is fixedly installed at the bottom of the incubator.

[0023] like Figure 1 As shown, by installing a number of support columns 2 on the top of the support frame 1, and installing an insulation box 3 on the top of the support columns 2, the insulation box 3 can be supported. By installing a control panel at the bottom of the support frame 1, and the control panel is electrically connected to the drive motor 501 and the rotating motor 601, the start of the drive motor 501 and the rotating motor 601 can be controlled by the control panel.
