[0028] Working principle: When using the shell injection molding device, start the first cylinder 7 and the second cylinder 9, close the left mold 10 on the push plate 8 to the right mold 11, pour the shell material of the fan motor into the lower hopper 14, start the first motor 20 on the mounting plate 5, so that the extrusion screw 19 rotates, thereby conveying the raw material forward, and at the same time the heating sleeve 13 works, and the electric heating wire inside it heats the feeding pipe 12, thereby melting the raw material and squeezing it into the right mold 11, so that the fan motor shell is injection molded under the action of the left mold 10 and the right mold 11, and the cold water is pumped into the cold water pipe 18 through the water pump through the water inlet head 15 to cool the left mold 10 and the right mold 11, and then the injection molded fan motor shell is cooled and molded, and then the first The cylinder 7, the second cylinder 9 and the third cylinder 17 push the fan motor casing out of the left mold 10, thereby completing the injection molding of the fan motor casing. When it is necessary to mix the two fan motor casing injection molding materials, the worker pours the two materials from the two auxiliary buckets 202 respectively, and starts the second motor 204 in the installation box 203 at the same time, so that the two materials enter the lower hopper 14 and are stirred and mixed by the rotating stirrer 201. After mixing, open the valve 215 to allow the mixed materials to enter the feeding pipe 12, thereby reducing the labor intensity of the workers and improving the mixing efficiency of the two fan motor casing injection molding materials as much as possible. The stirrer 201 rotates, causing the second bevel gear 208 to rotate, causing the first bevel gear 20 7 rotates, thereby rotating the transmission shaft 206, rotating the regulating wheel 205, and evenly pouring the raw materials poured into the auxiliary bucket 202 into the lower hopper 14, thereby assisting the agitator 201 to mix the raw materials. The agitator 201 rotates, so that the third gear 209 rotates, the gear ring 210 rotates, the connecting rod 211 rotates, and the rotating rod 212 rotates. At the same time, the agitator 201 rotates, and the rotating rod 212 rotates in the opposite direction, so that the mixing blade 213 rotates, thereby assisting the mixer to mix and stir the raw materials. By setting the bearing 214, the rotation stability of the rotating rod 212 is improved. When the external pipe 32 needs to be quickly connected and fixed to the water inlet head 15, the slip ring 36 is slid upward so that the connecting rope 35 pulls the positioning circle The block 33 is completely retracted into the mounting head 31, pushing the external pipe 32 so that the mounting head 31 is stuck on the water inlet head 15, and the slip ring 36 is loosened. By setting the spring 34, the positioning round block 33 is reset, so that the positioning round block 33 is stuck in the water inlet head 15, thereby fixing the mounting head 31, and then the external pipe 32 is quickly connected and fixed to the water inlet head 15, and the double-suction self-priming pump connected to the external pipe 32 is started to pump cold water into the water inlet head 15 and the cold water pipe 18. When changing the water, the double-suction self-priming pump is started again (the double-suction self-priming pump is an existing product sold on the market, and the specific use thereof will not be described in detail here), the water in the cold water pipe 18 is pumped out, and then new cold water is replaced, and the water inlet head 15 and the mounting head 31 are fixed by setting the sealing gasket 37.
