The invention discloses a plastic decorating part injection molding device, which has the following working principle: firstly, plastic particle raw materials are poured into a hopper 203, then a partition motor 212 is started, an output shaft of the partition motor 212 drives a valve column 211 to rotate, the valve column 211 rotates to cause the plastic particles to intermittently fall into a feeding barrel 201 (every time the valve column 211 rotates 180 degrees, a fixed amount of plastic particles pass through a strip through hole in the middle of the valve column 211 and a discharge hole 2031), the plastic particles pass through an induction coil 202 when moving downwards in the feeding barrel 201, and if metal particles are doped in the plastic particles (sometimes the plastic particle raw materials are doped with metal, and defects exist in injection molded parts). When metal passes through the induction coil 202, the original magnetic field of the induction coil 202 is destroyed, so that the current in the induction coil 202 is changed, whether metal particles are doped in plastic particles can be judged through the change of a current signal, when the current signal is changed, the power of the electromagnet 205 can be cut off, the magnetic force between the electromagnet 205 and the iron sheet 208 disappears, the iron sheet 208 and the partition 209 are fixed into a whole, at the moment, the partition 209 can be quickly inserted into the feed barrel 201 through the separation groove 2011 under the elastic force of the reset spring 207, the feed barrel 201 is cut off (the length of the feed barrel 201 in the figure is not the actual length), the falling plastic particles and metal particles can be cut off and then fall onto the partition 209 which is obliquely arranged, the plastic particles doped with the metal particles can be collected through the separation groove 2011 under the action of gravity, and then the metal particles are screened out. And the shielding eyebrow 210 is provided to prevent plastic particles from going out through the sorting groove 2011. When the current signal is normal, the electromagnet 205 is activated, instantaneously generating a magnetic force to attract the iron piece 208 and the diaphragm 209 to the initial position, the return spring 207 is compressed, and the diaphragm 209 is completely moved to the outside of the feedwell 201.
The plastic particles then fall into the flexible pipe 309 and then move along the flexible pipe 309 into the injection molding tube 301, and simultaneously, the vibrator 308 is started, and the vibrator 308 vibrates to drive the flexible pipe 309 to vibrate, so that the plastic particles in the flexible pipe 309 are prevented from accumulating. When plastic particles enter the injection molding pipe 301, the injection molding motor 312 is started, an output shaft of the injection molding motor 312 drives the fixed gear 311 to rotate, the fixed gear 311 rotates to drive the driven gear 305 to rotate, the driven gear 305 rotates to drive the injection molding pipe 301 to rotate, the injection molding pipe 301 rotates to enable the plastic particles to move upwards in the injection molding pipe 301, meanwhile, a heating wire on the injection molding pipe 301 melts the plastic particles, then the melted plastic particles are recorded in a groove between the fixed forming die 103 and the movable forming die 104 in a closed state, cooling and solidification are waited, the fixed forming die 103 and the movable forming die 104 are opened, and molded plastic parts are taken out. The driving motor 110 needs to be controlled in the process, the driving gear 109 is driven to rotate by the output shaft of the driving motor 110, the toothed ring 108 is driven to rotate by the rotation of the driving gear 109, the two nut teeth 107 are driven to rotate by the toothed ring 108, the screw rod 106 is driven to linearly move by the nut teeth 107, and the movable forming die 104 moves along with the screw rod 106 due to the fact that the movable forming die 104 is fixed on the screw rod 106, and at the moment, the fixed forming die 103 and the movable forming die 104 are opened.
Before the fixed forming die 103 and the movable forming die 104 are opened or closed, a cooperative electric cylinder 306 (the fixed forming die 103 and the movable forming die 104 need to be coated with grinding tool lubricating oil) needs to be controlled, and a telescopic rod of the cooperative electric cylinder 306 drives the injection molding pipe bracket 302 to vertically move on the vertical sliding pipe 303 through the connecting rod 304. When moving upward, the injection tube 301 approaches the movable mold 104, and when moving downward, the injection tube 301 moves away from the movable mold 104. In synchronization, when the injection molding tube 301 moves downward, the driven gear 305 is in separate engagement with the fixed gear 311 (the injection molding motor 312 is required to be in a closed state as long as the cooperative electric cylinder 306 is started), and when the injection molding tube 301 moves upward, the driven gear 305 is in engagement with the fixed gear 311, and the transmission between the injection molding motor 312 and the extrusion screw 310 can be thoroughly cut off in the process, so that a button for controlling the injection molding motor 312 is prevented from being touched by mistake.
