Sand turning device for manufacturing fine sand mold for casting

Abstract

The invention relates to the technical field of metal casting dies, in particular to a sand turning device for manufacturing a fine sand mold for casting. The device comprises a mixing box, a liftingmechanism, a mixing mechanism, a feeding pipe, a cover plate, a first pull handle, a discharging pipe and a discharging mechanism, wherein the middle of the top of the mixing box is fixedly connectedwith the bottom of the lifting mechanism, the bottom of the lifting mechanism is fixedly connected with the top of the mixing mechanism, the bottom of the mixing mechanism penetrates through the middle of the top of the mixing box and is movably connected with the mixing box, the discharging pipe is fixedly communicated with the bottom of the side surface of the mixing box, the discharging mechanism is connected to one side of the discharging pipe, and the bottom of the discharging mechanism is connected with the discharging pipe. According to the mixing mechanism, the mixing mechanism is adopted to mix the fine sand in the mixing box and the adhesive colloid, the mixing mechanism is driven by the lifting mechanism to ascend and descend, so that the mixing mechanism can fully mix the finesand and the adhesive colloid in the mixing tank, the quality of finished products caused by agglomeration caused by layering is prevented, and the preparation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metal casting molds, in particular to sand turning equipment for manufacturing fine sand molds for casting. Background technique [0002] Casting is a kind of metal thermal processing, which plays an important role in industrial development. Casting is to melt a metal into a liquid, and then inject hydraulic pressure into the mold to obtain a casting. Because the metal is hydraulically cooled and solidified, it has a strong cohesiveness. , so only the fine sand is used to make the casting mold, but when the fine sand is made into the casting mold, a certain amount of bonding colloid needs to be added to the fine sand, and the fine sand and the bonding colloid are mixed evenly, but the fine sand and bonding colloid The colloid is mixed by artificial sanding, and it is difficult to control the ratio of fine sand and adhesive colloid through artificial sanding, and it is difficult to mix fine sand and adhesi...
