The first adjusting rotating rod 236 is driven to rotate by rotating the adjusting knob 237, so that the adjusting threaded sleeve 238 moves on the outside of the first adjusting rotating rod 236, and the second adjusting rotating rod 239 is used to drive the adjusting sliding sleeve 240 and the adjusting card plate 241 to slide relative to each other. When the adjusting card plate 241 is engaged with the locking ring 233, the material guide rotating rod 230 and the material guide inclined plate 231 can be fixed, which is convenient for the storage of raw materials and the subsequent addition of additives or dyes to the injection molding raw materials.

[0045] Working principle: Before using this injection molding device for the production of tiny silicone earplugs, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig.12 As shown, first, the raw material is poured into the crushing box 224 through the feed hopper 225, and the first crushing roller 227 and the meshing gear assembly 228 are driven to rotate by the crushing motor 226, so that the meshing gear assembly 228 drives the second crushing roller 229 to rotate, so that the injection molding raw material can be quickly crushed, which is convenient for mixing and heating the injection molding raw material. The material guide rotating rod 230 and the counterweight block 232 at the bottom of the material guide inclined plate 231 can realize automatic unloading of the material guide inclined plate 231, and at the same time, the first adjusting rotating rod 236 is driven to rotate by rotating the adjusting knob 237, so that the adjusting threaded sleeve 238 moves outside the first adjusting rotating rod 236, and the second adjusting rotating rod 239 is used to drive the adjusting sliding sleeve 240 and the adjusting clamping plate 241 to slide relative to each other. When the adjusting clamping plate 241 is engaged with the clamping ring 233, the material guide rotating rod 230 and the material guide inclined plate 231 can be fixed, which is convenient for storing the raw materials and adding additives or dyes to the injection molding raw materials later.

[0046] Secondly, the lifting motor 202 is used to drive the lifting threaded rod 203 to rotate, so that the lifting threaded sleeve 204 drives the lifting support plate 205, the heating box 206 and the mixing box 207 to move up and down, so that the delivery nozzle 222 is moved to the top of the injection hole 122 for injection molding. The heating box 206 can heat the injection molding material inside the mixing box 207 to keep the injection molding material fluid, which is convenient for injection molding of tiny silicone earplugs. The mixing motor 208 drives the mixing tripod 209 to rotate, and the meshing connection between the mixing active gear 210, the mixing driven gear 211 and the meshing gear ring 212 is used. The mixing driving gear 210 can rotate on its own and revolve around the mixing driving gear 210 at the same time, and the first mixing spiral blade 215 and the second mixing spiral blade 216 are used to fully stir the raw materials and improve the mixing effect of the raw materials. The second mixing spiral blade 216 drives the stirring bracket 217 and the spiral cleaning blade 218 to rotate, and the inner wall of the mixing box 207 can be cleaned to avoid residual raw materials, thereby affecting subsequent injection molding. The stirring bracket 217 drives the conveying spiral blade 219 and the conveying cone head 220 to rotate, and the injection molding of the tiny silicone earplug is realized through the conveying pipe 221 and the conveying nozzle 222.

[0047] Finally, the switching motor 103 is used to drive the switching worm 104 to rotate, and the meshing connection between the switching worm 104 and the switching worm wheel 105 is used to realize the uninterrupted switching of the bottom mold body 111 and the top mold body 117, so as to realize the uninterrupted production of tiny silicone earplugs. By pressing the top of the connecting rotating plate 119, the connecting rotating plate 119 is rotated around the connecting rotating support 118. When the engaging pin 121 is separated from the connecting block 112, the top mold body 117 can be taken out from the top of the bottom mold body 111, which is convenient for rapid cooling of the injection molded product. By pressing the bottom mold body 111 downward, the bottom mold body 111 drives the extrusion connecting rod 114 and the airbag pressing plate 113 to extrude the recoverable airbag 108, so that the gas inside the recoverable airbag 108 is ejected through the air guide hose 109 and drives the ejection block 116 to move upward, so that the injection molded product can be ejected from the bottom mold body 111. The inside of the mold body 111 is ejected, thereby improving the efficiency of rapid demoulding of the injection molded product. By gently pressing the bottom mold body 111, the gas inside the recoverable airbag 108 can be used to quickly cool the injection molded product, thereby improving the efficiency of injection molding. The guide bracket 129 and the guide bevel 130 on the top of the top mold body 117 can be used to quickly guide the delivery pipe 221 and the delivery nozzle 222, so that the delivery nozzle 222 can be quickly aligned with the injection hole 122 on the top of the top mold body 117, thereby improving the accuracy of injection molding. When the injection molding is completed, by moving the delivery nozzle 222 upward, under the elastic force of the limit spring 127, the limit sliding sleeve 126 drives the limit sliding plate 128 and the guide bracket 129 to move relative to each other, so that the injection molding material at the bottom of the delivery nozzle 222 can be cut off to avoid the phenomenon of residual injection molding material, thereby affecting the subsequent injection molding work.
