Description

Technical Field

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

[0002] Lost foam casting is a new casting method that uses a foam plastic model for casting. By combining binder-free dry sand with vacuum pumping technology, high-precision and high-quality casting production can be achieved. Lost foam casting, also known as full-mold casting, is an advanced casting process and is hailed as a "revolution" in the history of casting. It uses a foam plastic model similar in size and shape to the casting. After being dipped in refractory coating and dried, it is vibrated and molded in dry quartz sand, and poured under negative pressure, causing the model to gasify and the liquid metal to occupy the position of the model. After solidification and cooling, the casting is formed. This method does not require mold removal, has no parting surface, and no sand core. Therefore, the casting has no flash, burr, and draft angle, reducing the dimensional error caused by the combination of sand cores. The advantages of lost foam casting include good casting quality, low cost, unlimited material, high dimensional accuracy, smooth surface, few internal defects, and the ability to achieve large-scale and mass production. In addition, it can improve the working environment, reduce labor intensity, and reduce energy consumption, and is hailed as the green casting method in the 21st century. EPS board is the abbreviation of expandable polystyrene board. It is a polystyrene foam plastic board with a closed-cell structure made by heating and pre-expanding expandable polystyrene beads and then heating and forming them in a mold. It is made from raw materials through pre-expansion, aging, forming, drying, and cutting. It can be made into foam products with different densities and shapes, and can also produce various foam boards with different thicknesses. It is widely used in the fields of construction, insulation, packaging, refrigeration, daily necessities, and industrial casting. It can also be used for the manufacture of exhibition venues, commodity showcases, advertising signs, and toys. To meet the national building energy conservation requirements, it is mainly used for external wall external insulation, external wall internal insulation, and floor heating of exterior walls. With the development of society, when the foam board needs to be cut, a cutting device is used.

[0003] Existing equipment such as CN212218615U, a cutting device for lost foam boards, includes a frame, a conveyor belt, and a cutting device arranged on one side of the conveyor belt. Support feet are provided below the frame. The cutting device includes an L-shaped frame and a cutting disc. The L-shaped frame is arranged on one side of the frame. A telescopic cylinder is fixed to the upper part of the L-shaped frame, and a driving motor is installed at the output end of the telescopic cylinder. The cutting disc is installed at the output end of the driving motor. A through groove is provided below the cutting disc, and the through groove is located on the frame. A collection bin is arranged below the frame in cooperation with the through groove. A brush strip is arranged above the frame in cooperation with the through groove. A U-shaped plate is arranged above the conveyor belt. A limiting mechanism is arranged on one side of the U-shaped plate. This device adopts the limiting mechanism. Through the acting force of the spring, the pressing wheel can change its height, which is suitable for foam boards of different heights. The acting force of the spring limits the foam board, and after the pressing wheel presses the foam board, it cooperates with the cutting disc for cutting. After cutting, the brush strip is used to clean the residues and dust on the conveyor belt. The structure is simple and practical.

[0004] When workers need to cut foam boards, they place the foam boards on the cutting device for the cutting device to process the foam boards. However, when the cutting device cuts the foam boards, it will first squeeze the foam boards, resulting in the foam boards being subjected to a thrust force and moving during the processing, and thus the processing process of the foam boards will be affected.
