The utility model relates to a pyrolysis activation all -in -one of resin resourceful regeneration, including pyrolysis activation jar, feed pipe, flue gas pipeline and preheating utilization mechanism, the pyrolysis activation jar side intercommunication has flue gas pipeline, is equipped with the feed pipe at the top, preheating utilization mechanism installs at the feed pipe surface, and with flue gas pipeline exhaust end intercommunication, hot gas in pyrolysis activation jar passes through flue gas pipeline and enters into rotary pipeline inside, and the inside rotary pipeline is equipped with heat conduction sleeve, and heat conduction sleeve surface is opened with the spiral groove of rotary pipeline adaptation, and the contact area of rotary pipeline and heat conduction sleeve increases, better heat absorption of rotary pipeline is absorbed to heat conduction sleeve surface, and is given to feed pipe, and the resin passes through the feed frame of external equipment and enters the feed pipe, wherein the external equipment is equipped with control valve, and the resin in feed pipe is preheated and handled, and the feed pipe surface is equipped with the heat preservation frame, can lock the heat, reduces the loss of heat.

This application discloses an automotive wheel hub mold with upper and lower split side molds, including an upper mold, a lower mold, and several side molds. The side molds include a front wheel rim side mold and a rear wheel rim side mold that fit together vertically. The front wheel rim side mold is equipped with a cooling device. This cooling device guides the cooling medium to uniformly and rapidly cool the thickness portion where the front wheel rim connects to the spokes. It includes a cooling chamber, a reflector plate, a water inlet pipe, and a return pipe. The reflector plate is located at the top of the cooling chamber. One end of the water inlet pipe extends into the cooling chamber and slopes upwards towards the reflector plate. The core solution employs a cooling device with a reflector plate. Through optimized pipe structure and program control, uniform dispersion and cooling of the cooling medium are achieved, improving the casting efficiency and solidification quality of this type of wheel, while reducing localized thermal shock to the mold and reducing the risk of surface cracking.
