Noise-reducing sand mixing device for foundry machinery

Abstract

The invention relates to a noise-reducing sand mixing device for foundry machinery. The noise-reducing sand mixing device for foundry machinery comprises a top cover and an upper through slot, whereina handle is fixed to the upper right end of the top cover, and an inner groove is formed in the inner side of the top cover; a flying ring screw is placed on the inner side of the inner groove, and abase is mounted at the lower end of the flying ring screw; a body is arranged below the top cover, and a pore is formed in the upper end of the body in a penetrating manner; an inner chamber is arranged in the body, and a supporting seat is fixed to the right end of the body; a chute is formed in the supporting seat, and a slide bar is joined in the inner end of the chute. The noise-reducing sandmixing device for foundry machinery provided by the invention has the beneficial effects that the noise-reducing sand mixing device for foundry machinery is provided with a sliding seat and a slideway; the sliding seat and the slideway slide, so that a sealing bolt is slidably adjusted to achieve the purpose of opening and closing the upper through slot; a micro motor works to drive an indented wall to move through a gear, so as to provide abundant power for sliding of the sliding seat.

Description

technical field [0001] The invention relates to the technical field of casting devices, in particular to a noise-reducing sand mixing device for foundry machinery. Background technique [0002] Casting is a relatively early metal thermal processing technology mastered by humans. It has a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC. The technology has reached a very high level. Casting is a method of casting liquid metal into a casting cavity that is suitable for the shape of the part. After it is cooled and solidified, the method of obtaining parts or blanks is mostly the metal that is originally solid but heated to liquid state. The material can be sand, metal or even ceramics, and the methods used will vary according to different requirements. [0003] Due to the large number of mechanical parts in the main body of the existing sand mixing device, the body will generate a lot of noise when it is in operation, w...

Problems solved by technology

[0004] The object of the present invention is to provide a noise-reducing sand mixing device for foundry machinery, to solve the problem that the existing sand mixing device proposed in the above background technology has more mechanical parts in the main body, so that the machine body will generate more noise during operation. Loud noise will affect the staff who use it and cause some damage to their hearing, and the general main body is difficult to adjust conveniently during use, which makes the main body relatively cumbersome to use, and there are many unfavorable problems
