Embodiment 1

[0029] The power ultrasonic device used for casting molds in the iron mold sand-coated production line, the sand box 1 is located on the box rail 2; the track 5 is set parallel to the box rail 2; the ultrasonic processing device frame 4 is placed on the track 5 and moves horizontally along the track 5; The ultrasonic processing device 3 is fixed on the ultrasonic processing device frame 4 , and the ultrasonic processing device 3 is in close contact with the wall of the sand box 1 by adjusting the height of the ultrasonic processing device frame 4 . The sand box 1 includes an upper sand box 6 and a lower sand box 7, the upper sand box 6 and the lower sand box 7 are respectively provided with gates, runners and mold cavities, and the upper sand box 6 and the lower sand box 7 are combined and placed On the track of the box rail 2, a pulley A8 is arranged on the top of the box rail 2, and the lower sand box 7 contacts the box rail 2 through the pulley A8, and the sand box 1 is move...

Embodiment 2

[0033] Cover the cavity of the upper sand box 6 and the lower sand box 7 of the sand box 1 with sand. After the sand coating is completed, put the upper sand box 6 and the lower sand box 7 up and down to close the box, and use the fasteners to make the upper and lower sand boxes tight. In combination, the sand box after the box closing is completed is placed on the box rail 2.

[0034] Fix the ultrasonic processing device 3 on the fixed frame 15 on the ultrasonic processing device frame 4, move the ultrasonic processing device frame 4 on the track 5, and the track 5 is parallel to the box rail 2; turn the hand wheel rotating rod 17 counterclockwise to make the ultrasonic processing device 3 Move away from the sand box 1 along the slide rail 14, pour the smelted metal into the sand box 1, adjust the ultrasonic processing device frame 4 to the middle part of the sand box 1, and turn the handwheel rotary rod 17 clockwise to make the ultrasonic processing device The ultrasonic pro...

Abstract

The invention provides a power ultrasound device and method for an iron mould sand coated production line casting mould. The device mainly comprises sanding boxes, a box rail, an ultrasonic treatment device, an ultrasonic treatment device support, a rail, a base, a sliding rail, a fixing support, a rotating rod support, a hand wheel rotating rod and a sliding wheel. According to the method, ultrasounds are applied to the casting mould in the metal setting process, an ultrasonic probe and the lower sanding box are in tight contact, the good transmissibility of ultrasonic waves in solid is used, the power ultrasounds can be evenly applied to all portions of the casting mould, and the special effect of the ultrasonic waves is used for achieving even casting ingredients and refined textures; and meanwhile, all defects in a casting are eliminated, and the metal casting quality is improved. The device is arranged on the rail parallel to the production line, and therefore power ultrasound treatment can be applied to the production line more conveniently and quickly, the production efficiency is improved, and the device and method are suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and relates to a device and method for applying power ultrasound to casting molds of an iron mold sand-coated production line. Background technique [0002] With the development of metallurgical technology, a series of new technologies have emerged continuously, and the uniformity of the casting structure has been improved. Although the gas and impurities have been continuously reduced, the quality of the castings is far from reaching the highest level. In order to further improve the mechanical properties of castings and other metal products, a series of measures such as heterogeneous nucleating agents, physical field treatment, and temperature control treatment have been continuously proposed. Among them, ultrasonic processing technology is the most representative one in physical field processing technology. [0003] Ultrasound has been widely used in a wide range of fields,...
