Automatic sand-mixing batching system for core-making machine

Abstract

The invention belongs to the field of core-making machines and particularly discloses an automatic sand-mixing batching system for a core-making machine. The automatic sand-mixing batching system comprises a mixing hopper and a plurality of horizontally-arranged weight balancing mechanisms. The at least three weight balancing mechanisms are used for weight balancing of crude sand, black resin andwhite resin, and the weight balancing mechanisms are electrically connected to a PLC control system to control so that weight balancing of all the weight balancing mechanisms can be controlled. The mixing hopper is located below the multiple weight balancing mechanisms, and all batched raw materials with balanced weights are put into the mixing hopper through the corresponding weight balancing mechanisms to be evenly mixed. According to the automatic sand-mixing batching system, the core sand materials with different formula proportions can be batched for the crude sand of different specifications, thus various products are manufactured through the cold-core box core-making machine, the optimum raw material ratio can be screened out according to the quality of the products, and the problemthat the efficiency is low due to traditional manual operation is solved.

Description

technical field [0001] The invention relates to the field of core making machines, in particular to an automatic sand mixing and batching system for core making machines. Background technique [0002] The cold box core making machine is used to make sand cores, which are mainly used to form the inner cavity, holes and shape pits of castings. This process has a short core-making cycle and no problem of thermal deformation of the core box, making the sand core dimensional accuracy high. The main raw material for making core sand is a mixture of raw sand, black resin and white resin, and the weight and ratio of black resin and white resin required for each specification of raw sand affect the quality of the sand core. Therefore, for It is very important to quickly find the best ratio of black resin and white resin for each specification of raw sand. [0003] At present, manual sand mixing is usually used, but manual sand mixing leads to a decrease in work efficiency and seriou...
