Regulating device for optimizing vibration frequency of vibrational casting machine

Abstract

The invention discloses a regulating device for optimizing the vibration frequency of a vibrational casting machine. The regulating device comprises a bottom plate, a vibration buffering chamber, a vibration case, a casting mold case and a vibration start device. The vibration buffering chamber is arranged on the upper portion of the bottom plate. The upper portion of the vibration buffering chamber is fixedly connected with the lower portion of the vibration case. The bottom of the vibration case is fixedly connected with a vibration buffering plate. The vibration buffering plate is located in the middle inside the vibration buffering chamber. Both the upper side and the lower side of the vibration buffering plate are fixedly connected with vibration buffering springs, and the outer side ends of the vibration buffering springs are fixedly connected with the inner wall of the vibration buffering chamber. The vibration start device is arranged inside the vibration case. A mold thermal insulation wall is arranged on the inner wall of the casting mold case. A cavity is formed inside the mold thermal insulation wall. A casting mold is arranged inside the cavity. The regulating device is simple in structure, external air can be exhausted, bubbles are prevented, the vibration frequency is adjustable, the vibration strength is gentle, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the field of casting equipment, in particular to an adjusting device for optimizing the vibration frequency of a vibration casting machine. Background technique [0002] Casting is one of the basic processes of modern machinery manufacturing industry. As a metal thermal processing technology, casting has gradually matured in my country. Foundry machinery is to use this technology to smelt metal into a liquid that meets certain requirements and pour it into the mold. After cooling, solidification, and cleaning, all the mechanical equipment that can be used to obtain castings with predetermined shape, size and performance, Also known as casting equipment. Gravity casting refers to a process in which molten metal is poured into a metal cavity under the gravity of the earth to obtain a casting. Gravity casting in a broad sense includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; gravity...

AI Technical Summary

Problems solved by technology

[0003] The existing gravity casting equipment has the following defects: 1. During casting, a small amount of air will be brought into the liquid metal raw material during the pouring process, causing air bubbles inside the cast product, which affects product quality; 2. The existing vibration casting machine, the vibration frequency is not easy to adjust, and it is inconvenient to adjust to the optimal vibration frequency according to different product attributes; 3. The existing vibration device, that is, the device used to generate vibration, has a large vibration intensity and is not suitable for use For casting machinery, because it will cause greater wear and tear on the casting machine itself
