Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, specifically to a lost foam transfer device. Background Technology

[0002] Lost foam casting (also known as solid casting) is a new casting method that uses foamed plastic (EPS, STMMA or EPMMA) polymer material to make a solid mold that is exactly the same as the structure and size of the part to be cast. After being coated with refractory coating (for strengthening, smoothing and air permeability) and dried, it is buried in dry quartz sand and shaped by three-dimensional vibration. Molten metal is poured into the casting sand box under negative pressure, causing the polymer material model to be heated and vaporized and extracted, and then replaced by liquid metal, which cools and solidifies, forming a new one-time molding casting process to produce castings.

[0003] Castings vary in size depending on customer customization requirements, therefore sand boxes are mostly quite large. The casting process involves many different stages, requiring the sand boxes to be moved to different locations. Existing technologies mostly require manual movement of the sand boxes, which is inefficient and labor-intensive. Therefore, this application proposes a lost foam casting transfer device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lost foam casting transfer device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lost foam casting transfer device, the device comprising:

[0006] The system includes a control panel, a ramp 1, a conveyor belt support frame 2, a drive motor 3, a conveyor belt 4, and an unloading platform 6; wherein the ramp is located at the first end of the conveyor belt 4 and is used to transport the lost foam casting sand box onto the conveyor belt 4.

[0007] The drive motor is used to drive the conveyor belt to move the sand box to different working positions under the control of the control panel; the unloading platform 6 is set at the second end of the conveyor belt 4 and is used to automatically unload the castings in the sand box.

[0008] In one possible implementation, the device further includes an unloading platform bracket 5 for supporting the unloading platform 6.

[0009] In one possible implementation, the device further includes: a support rod 9, a positioning pin 10, a support frame 11, a movable shaft 12, a hydraulic cylinder 13, and a slide 16.

[0010] The unloading platform 6 is movably connected to the support frame 11 via the movable shaft 12. The hydraulic cylinder 13 is used to tilt the unloading platform 6 via the support rod 9, and the support rod 9 is provided with a sliding groove 16.

[0011] In one possible implementation, the device further includes a casting cooling box 14 for receiving a sand box, dry sand, and castings.

[0012] Compared with the prior art, the present invention provides a lost foam casting transfer device, which has the following beneficial effects:

[0013] During operation, the lost foam sand box is placed at the first end of the conveyor belt via a ramp. The conveyor belt, controlled by a control panel, sequentially transports the sand box to the sand bed preparation work point, the model placement work point, the sand filling work point, and the sealing and shaping work point. The sand box is then transported to the unloading platform. Driven by hydraulic cylinder 13, the unloading platform tilts, emptying the dry sand and castings from the sand box for cooling. The fully automated control of the sand box's movement at different work points throughout the entire casting process significantly improves the efficiency of sand box transfer.
