Disclosure of Invention
The utility model aims at providing a lower problem of production efficiency when solving the psammitolite of many of present simplex position core making machine production a mould, provide a core making machine is used in casting.
The utility model has the following concrete scheme: a core making machine for casting comprises a frame, a working platform is arranged at the lower end of the frame, a sand silo is arranged at the upper end of the frame, a lower die mounting plate is arranged in the middle of the working platform, a detachable lower die is arranged at the top of the lower die mounting plate, an oil cylinder is arranged in the middle of the upper end of the frame, an upper die mounting plate is arranged vertically downwards and at the end of a piston rod of the oil cylinder, a detachable upper die is arranged at the bottom of the upper die mounting plate, a resistance wire is arranged in the upper die mounting plate, lead wires at two ends of the resistance wire penetrate out of the upper die mounting plate and are connected with a heating power supply, the sand silo is symmetrically arranged at two sides of the oil cylinder, sand guide hoses are arranged at the bottom of the sand silo, two groups of slideways are symmetrically arranged on the working platform, a cylinder is arranged in the middle of each group of slideways, the interior of the sand inlet hole is communicated with the cavity.
The periphery of bed die mounting panel is equipped with four direction pillars, go up and correspond four direction pillars department on the mould mounting panel and be equipped with direction pillar complex linear bearing.
The utility model discloses still include the controller, the controller is connected with hydro-cylinder control valve, heating power respectively, is equipped with the time relay that can set up time in the controller, and time relay begins timing simultaneous control ware control heating power work and heats the resistance wire when hydro-cylinder control goes up mould and bed die compound die, and controller control heating power closes when the timing finishes, and the simultaneous control hydro-cylinder piston rod retracts.
The working principle of the utility model is as follows: when the core is manufactured, the oil cylinder moves to enable the upper die and the lower die to be matched, then the air cylinders on the two sides move to enable the sand shooting ports of the sand shooting devices to be in butt joint with the sand inlet holes of the dies, the air cylinders enable the sand shooting devices to return after the sand shooting devices complete the sand shooting movement, meanwhile, the heating power supply works to enable the sand cores in the cavities to be rapidly heated up, the heating is stopped after the set time is reached, the piston rods of the oil cylinders retract to perform demolding, and then the single sand core manufacturing of a pair of dies is.
Compared with the prior art, the utility model has the following advantages: the sand inlet holes are formed in the two sides of the mold, the sand shooting devices are arranged on the two sides of the mold, and a plurality of sand cores can be manufactured at one time, so that the production efficiency is improved.
