Aluminum generator shell mold

Abstract

The aluminum generator shell mold comprises a hydraulic cylinder, the movable end of the hydraulic cylinder is fixedly connected with a lifting bottom plate, welding supporting legs are installed at the four corners of the top of the lifting bottom plate in a welded mode, and a workbench is connected to the tops of the welding supporting legs in a welded mode. According to the aluminum generator shell mold, the traditional preparation process is simplified, compression molding can be achieved only by placing the middle mold on the top of the mold bottom plate and guiding green sand into the middle mold, the process is simple and rapid, mechanical hydraulic compaction and manual compaction operation are more convenient, and during demolding, the production efficiency is greatly improved. During demolding, the middle mold directly moves upwards, and the green sand and the shell workpiece are directly separated in a vertical linear manner, so that demolding can be performed quickly and conveniently, a mold core cannot be deformed, and the subsequent casting precision can be ensured.

Description

technical field [0001] The invention relates to the field of shell molds, in particular to an aluminum generator shell mold. Background technique [0002] A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. It is then converted into electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive materials to form magnetic circuits and circuits ...

AI Technical Summary

Problems solved by technology

[0003] Currently, green mold sand is often used to prepare aluminum generator shells. However, when green mold sand is used to prepare shell injection mold cavities, it is pressed layer by layer. , that is, place the bottom outer frame first, then place the outer shell workpiece in the outer frame, then pour green mold sand into the outer frame and compact it, and so on to superimpose the outer protective frame layer by layer and compact it, and in the Finally, when taking out the shell workpiece, it is necessary to knock the shell workpiece to make the contact gap between it and the green mold sand larger, and then take out the workpiece, which is not only inconvenient to demould, but also causes deformation of the formed core
