Casting-based sand injection device with homogenizing mechanism for sand mold cavity

Abstract

The invention provides a casting-based sand injection device with a homogenizing mechanism for a sand mold cavity, relates to the technical field of casting, and solves the problems that a traditionalsand injection device cannot effectively and uniformly inject sand into a sand mold, so that the injection amount of sand in the sand mold is easily deviated greatly, and the casting quality of a workpiece in the sand mold is influenced. The casting-based sand injection device comprises a sorting screen frame and a homogenizing screen frame, a support frame is mounted at the top of the base, twolead screws are installed at the top of the supporting frame, driven belt wheels are arranged at the right ends of the lead screws, and a linkage belt wheel is arranged at the left end of each lead screw; and a first driving piece is installed at the top of the right end of the supporting frame and electrically connected with a control electric box through a circuit, and the front end and the rearend of an upper shell are each provided with a nut. According to the casting-based sand injection device, the homogenizing screen frame moves front and back, sand stored in a lower shell is evenly screened into the sand mold at the bottom of the lower shell, and the sand filling uniformity in the sand mold is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of casting, and more specifically relates to a sand material injection device with a material equalizing mechanism for a sand mold cavity based on casting. Background technique [0002] The molding materials used in sand casting are cheap and easy to obtain, and the casting molds are easy to manufacture. They can be adapted to single-piece production, batch production and mass production of castings. For a long time, they have been the basic process in casting production. Casting molds refer to Obtain the structural shape of the part, make the structural shape of the part with other easily formed materials in advance, and then put the mold in the sand mold, so a cavity with the same structural size as the part is formed in the sand mold, and then in the cavity The fluid liquid is poured in the middle, and after the liquid cools and solidifies, it can form a part with exactly the same shape and structure as t...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sand material injection device with a uniform material mechanism for the sand mold cavity based on casting, to solve the existing sand injection operation similar to the existing sand mold cavity, which usually requires manual labor. The sand material is screened and refined through the mesh screen first, and then the screened sand material is poured into the sand material injection device, which is labor-intensive and slow in efficiency, and the sand material cannot be effectively injected when the sand material injection device is used. Uniform injection into the sand mold will easily lead to a large deviation in the amount of sand injected into the sand mold, which will affect the casting quality of the workpiece inside the sand mold
