180、175~180、180~185、185~190、180~185℃。
S800, packing box wood plastic composite is melt into melt, mould is heated to predetermined temperature and closes mould,
Being injected by melt in the die cavity of Guan Bi mould, mould is carried out pressurize, after pressurize, cooling scheduled time die sinking is taken out and is i.e. obtained packaging
Box.
Wherein, packing box wood plastic composite is melt into the step of melt particularly as follows: by packing box wood plastics composite
Material is placed in the machine barrel of injection machine, heats injection machine, makes packing box wood plastic composite be melt into melt.Injection
The nozzle temperature of machine is 180 ~ 185 DEG C, the temperature from a district to 5th district is respectively as follows: 185 ~ 190,180 ~ 185,175 ~ 180,175 ~
180、170~175℃。
The step that mould is heated to predetermined temperature includes: uses surface gas full-boiled process, is quickly heated by mould with die heater
To predetermined temperature, predetermined temperature is 110 ~ 140 DEG C.
The method that surface gas full-boiled process is steam and chilled water combines realizes the intensification rapidly to mould and cooling.At mould
Cooling down after pressurize is also to use surface gas full-boiled process quickly to cool down, and saves cool time, reduces cost.Quick die heater is set
Maximum temperature be 140 DEG C, cooling minimum temperature be 70 DEG C.
The pressure of pressurize is 20 ~ 50MPa.
Take out matched moulds after packing box, after mould reaches predetermined temperature, repeat step S800, by that analogy.
Above-mentioned packing box preparation, owing to first preparing self-control ZH04A, material is sufficiently mixed uniformly by rear point three steps, will
Premix material extruding pelletization, obtains packing box wood plastic composite, after packing box wood plastic composite is melt into melt, will
Melt injects in the die cavity of Guan Bi mould, and mould is carried out pressurize, and after pressurize, cooling scheduled time die sinking is taken out and i.e. obtained packing box.
By such mode, it is possible to make the packing box product surface skinning obtained, the gloss appearance degree making packing box is unified, feel temperature
With, it is possible in big specification produces.
Below in conjunction with embodiment, the invention will be further elaborated.
