As preferably, the distance of described telescoping mechanism receding is identical with the spacing of cleaning plant with the external screw thread arranging on described screw rod, and the internal threaded end of described cleaning plant inner ring has chamfering. Easy cleaning device upper, after rotating and being coupled on screw rod, can move forward and backward cleaning plant.
As preferably, described permanent magnet coordinates with the hot-wire coil being arranged in injection moulding barrel. Hot-wire coil band in the time of energising is magnetic, and there is no magnetic when not charged, can effectively pin cleaning plant.
As preferably, the front end in described injection moulding barrel is also provided with limit switch. Limit switch can make servomotor reversion, makes cleaning plant backhaul.
As preferably, on described injection moulding barrel, be also provided with dismountable nozzle, described nozzle and injection moulding barrel threaded engagement. After cleaning completes, the threaded engagement place of nozzle is turned on, the space after turning on is large, can with hook or draw spoon be gathered in injection moulding barrel head waste material take out.
Compared with prior art: inner cleaning plant, utilize screw rod rotation to promote, drive internal cleaning to overstock impurity in barrel and the material powder of adhesion, realize different moulds, in injection machine, just with different material powder, reusable edible, is applicable to the working of plastics that precision is higher.
