Automatic seamless motor housing molding machine

Abstract

The invention relates to an automatic seamless motor housing molding machine, and relates to a motor manufacturing technology. The machine comprises a frame and a workbench arranged on the frame. Supporting rods extend upwards from two sides of the frame. A cross beam is connected on the upper ends of the supporting rods. Slide rod assemblies are arranged on two sides of the cross beam. An inner shape sand box is arranged below the cross beam. A rectangular connection piece is fixedly connected on the periphery of the inner shape sand box. Gas cylinders are connected on two sides of the rectangular connection piece. The ends of piston rods on the front ends of the gas cylinders are fixed on the rectangular connection piece. The back ends of the gas cylinders are slidably connected on the slide rod assemblies through sliding parts. An inner shape molding mold elevation groove is arranged on one side of the workbench, and an outer shape molding mold accommodation recess is arranged on the other side of the workbench. An outer shape mold is arranged on the outer shape molding mold accommodation recess. An elevation gas cylinder is connected to an outer-upper pressing plate on the outer shape mold. A sand feeding pipe is connected to the outer shape mold. An elevation mechanism is arranged on the bottom of the inner shape molding mold elevation groove. An inner shape molding mold is fixed on the elevation mechanism. An ejection-pressing device is arranged above the inner shape molding mold, and is connected to an ejection-pressing gas cylinder which is arranged on the cross beam. With the machine provided by the invention, a manufactured product has no crack caused by mold seam of a splicing-type mold. The surface of the product is more smooth and beautiful.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a fully automatic seamless motor shell molding machine. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery; thus, the application range of the motor is very wide; and the quantity that needs to be manufactured every year is also extremely large. The motor will generate a certain amount of heat during the working process. In order to improve the heat dissipation efficiency of the motor to ensure the normal operation of the motor; for example, there are multiple heat dissipation strips on the outer surface of the Y series three-phase motor housing; but the housing mainly relies on Mold foundry casting molding blank. [0003] The mold used for the ...

Problems solved by technology

Making casting molds using this split mold requires skilled molders to take out the sub-moulds of the split mold piece by piece, which can easily cause sand pouring when taking the mold. The mold requires a high level of proficiency and experience for the molders; Increased production requirements, increased production costs and low production efficiency
