Self-feeding foundry sand molding machine

Abstract

The invention discloses a self-feeding foundry sand molding machine. The self-feeding foundry sand molding machine comprises a base. A support plate is welded to the back face of the top of the base.A top plate is welded to the top of the support plate. A first air cylinder is connected to the top of the support plate through bolts. The bottom of the first air cylinder penetrates the top plate and extends to the bottom of the top plate. The bottom of the first air cylinder is connected with a pressure plate through bolts. The two sides of the top of the base are correspondingly connected withvibrating motors through bolts. Vibrating columns are movably connected to the tops of the vibrating motors. The tops of the vibrating columns are connected with a bottom plate through bolts. A sandbox is movably mounted on the top of the bottom plate. According to the self-feeding foundry sand molding machine, through the cooperation of a control box, telescopic sleeves, support rods, pressuresensors, support springs, a sand storage box, a sand outlet pipe, an electric telescopic rod and an electric valve, the problem that an existing foundry sand molding machine does not have the self-feeding function, complex feeding still cannot be solved, and consequently the production efficiency is low is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a molding sand molding machine capable of self-loading. Background technique [0002] Molding sand is used for molding in casting. In the early days, it was purely manual operation. Not only did it need to fill the sand manually, but it also had to be manually shaken. In this case, the quality of the produced model is poor, and it often takes multiple operations to get a qualified one. After the development of technology, the sand molding machine appeared, which replaced the manual shock and made great progress in work efficiency and yield. However, in the actual use process, it is still necessary to manually put the sand into the mold. And it needs multiple operations to fill the mold cavity, long hours of work, relatively large consumption of people's physical strength, and low efficiency. A kind of molding sand molding machine that can produce sand by itself has b...
