Abstract

A centralized sand mixing device for cold core manufacturing comprises a walking mechanism, a stirring mechanism and a sand discharging mechanism; the walking mechanism comprises a walking trolley, and a walking motor driving the walking trolley to operate along a rail; the stirring mechanism comprises a stirring barrel, a rotor and a driving device; the stirring barrel is installed on the walkingtrolley; a sand discharging port is formed in the outer wall of the lower portion of the stirring barrel; the rotor is mounted at the bottom of the stirring barrel; three groups of blades are arranged on the outer wall of the lower part of the rotor; each group of blades comprises an arc-shaped blade and a straight blade which are sequentially arranged from top to bottom; the arc-shaped blades and the straight blades are uniformly arranged along the circumferential tangential direction of the outer wall of the rotor, and the straight blades are obliquely arranged; the rotor is connected withthe driving device under the stirring barrel; the sand discharging mechanism comprises a cylinder and a sand discharging door connected with each other; and the sand discharging door is matched with the sand discharging port. The centralized sand mixing device is small in occupied space, low in maintenance cost, high in sand mixing efficiency, good in sand mixing and discharging effect and high inreliability.

Description

technical field [0001] The invention relates to the technical field of core making, in particular to a centralized sand mixing device for cold core core making and a control method thereof, which are mainly suitable for reducing occupied space, reducing maintenance costs, and improving sand mixing efficiency. Background technique [0002] The preparation of core sand is an important part of the casting process. In this process, sand needs to be mixed evenly with binders, curing agents or other additives to prepare core sand. The vertical lifting sand mixing mechanism and the blades of the existing sand mixing device have poor effect, and the sand mixing is uneven, resulting in core waste. In addition, each of the multiple Lanpe cold core making machines equipped in the core making workshop has a set of sand mixing devices, resulting in a large volume of cold core making machines and occupying a large amount of workshop space. At the same time, the pipeline of the sand mixin...
