Description

Technical Field

[0001] The utility model belongs to the technical field of lost foam casting, and particularly relates to a sand box platform for lost foam casting. Background Art

[0002] Lost foam casting (LFC) is a novel casting method that uses binderless dry sand and vacuum technology to create full-mold casting using foam plastic molds. Foam patterns similar in size and shape to the casting are bonded together into a pattern cluster. After being coated with a refractory coating and dried, the pattern cluster is embedded in dry quartz sand and vibrated to form the pattern. Poured under negative pressure, the pattern vaporizes, allowing liquid metal to occupy the pattern space. After solidification and cooling, the casting forms. Compared with traditional casting techniques, LFC offers the following advantages: high casting quality and low cost; a wide range of materials and sizes; high dimensional accuracy, smooth surfaces, minimal cleaning and machining, significantly reduced internal defects, and dense microstructure, enabling large-scale and mass production. Automated production lines are environmentally friendly and can significantly improve the working environment, reduce labor intensity, and reduce energy consumption. The LFC casting process requires the use of a flask platform. However, current flasks, which need to be filled with wax patterns and casting sand, can easily become uneven when adding filler, resulting in gaps within the flask, which can affect the performance of the LFC. Therefore, a LFC flask platform is needed. Utility Model Content

[0003] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a sand box platform for lost foam casting, which solves the problem that during the use of the current sand box, since the sand box needs to be filled with wax molds and casting sand, adding filling materials may easily cause the sand box to not reach a flat state, resulting in gaps in the sand box, which in turn affects the lost foam casting.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand box platform for lost foam casting, comprising a fixed plate, electric slide rails are fixedly installed on both sides of the top of the fixed plate, the surface of the electric slide rails is slidably connected to a slider, a connecting plate is fixedly installed on the top of the slider, a support plate is provided on the top of the connecting plate, a locking bolt is threadedly connected to the surface of the support plate, a casting sand box body is fixedly installed on the upper surface of the support plate, a knob sealing head is threadedly connected to the surface of the casting sand box body, a support rod is fixedly installed on the surface of the fixed plate, one end of the support rod is fixedly connected to a connecting plate, an electric push rod is fixedly installed on the surface of the connecting plate, and one end of the electric push rod is fixedly connected to a pressing plate.

[0005] Preferably, the support plate is connected to the connecting plate via locking bolts, and there are two support plates.

[0006] Preferably, the electric slide rail is connected to the connecting plate via a slider.

[0007] Preferably, a sealing gasket is provided on the surface of the pressing plate, and the pressing plate is located above the electric slide rail.

[0008] Preferably, a clean water tank is provided on one side of the fixed plate, a water inlet pipe is provided on the upper surface of the clean water tank, and a sealing cover is threadedly connected to the surface of the water inlet pipe.

[0010] Preferably, a support block is fixedly mounted on the bottom of the fixing plate, and a rubber pad is fixedly mounted on the surface of the support block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The electric push rod starts to drive the pressing plate to perform a downward pressing movement. After the downward pressing movement is adjusted, the pressing plate can extrude the filling material in the casting sand box body. After the filling material in the casting sand box body is squeezed, the filling material will move downward to achieve a flat state. After the filling material is squeezed, the filling material will fully contact the casting sand box body, so that the sand box can be fully filled, preventing gaps in the sand box and ensuring the lost foam casting effect.
