The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and it is not intended that to of the present utility model
Limitation.
The injection machine of the utility model embodiment is described below with reference to Fig. 1-Fig. 2.
Referring to Fig. 1, Fig. 2, the present embodiment barrel register includes barrel 1 and the heating element heater for being heated to barrel 1
3, the design temperature of the heating element heater 3 is higher than the target temperature of barrel 1, and heat exchange is provided between the barrel 1 and heating element heater 3
Space 4, the heat exchange space 4 are connected with air inlet pipe 5 and blast pipe 6.
During work, heat is first conducted to the air in heat exchange space 4 by heating element heater 3, in by heat exchange space 4
Space heat is reached into the surface of barrel 1, realize and barrel 1 heated.When temperature is too high in barrel 1, air is successively through air inlet
Pipe 5, heat exchange space 4, blast pipe 6, the partial heat in heat exchange space 4 is taken out of.
The barrel register of the present embodiment, material can be reduced in time by air inlet pipe 5, heat exchange space 4 and blast pipe 6
The temperature of cylinder, avoids injection machine and is stopped because of ultra-high temperature, improve operating efficiency；And the barrel register utilizes
Air in heat exchange space 4 is heated to barrel 1, and heating is more uniformly distributed, and avoids barrel hot-spot phenomenon, injection effect is more
It is good.
In detailed process is implemented, installed part 2 can be set in the periphery of barrel 1, and the installed part 2 is used to pacify heating element heater 3
