Summary of the invention
Technical problem to be solved by this invention: overcome the above-mentioned deficiency of prior art and simple a kind of hollow injection molding forming method is provided, it can need some the hollow injection moulded products of the band sealing of secondary operation processing; Design is carried out in mould, and oneself is final finished product to the hollow plastic spare of sealing when leaving die cavity.
The technical scheme that the present invention solves its technical problem employing is: a kind of hollow injection molding forming method, comprise moving plate, and dynamic model, the submodule drive unit, submodule is decided plate, cover half and injection mechanism; It is characterized in that: dynamic model, submodule, after the cover half matched moulds was finished, injection machine carried out action of injection, and die sinking was to the needs distance after injection was finished, dynamic model drives submodule by the submodule drive unit and mates next station, then again carry out mould assembling action, the different parts goods that originally separated are stitched together, then carry out biphasic injection, the different goods that separate are passed through plastic-injection together, finish the hollow injection moulded products.The present invention needs for the second time operation of processing to some, especially needs the hollow product of the band sealing of welding; Design is carried out in mould, and oneself is final finished product to the hollow plastic spare of band sealing when leaving die cavity, has improved product assembly quality stability and has cooperated compactness, has saved manpower and materials and factory building space.
Described submodule drive unit can be driven by the rotation oil motor, or electrical motor driven, or hydraulic oil cylinder driving; The hollow product that needs moulding can be goods symmetrical or that equate, also can be asymmetric or unequal goods, the plastic parts of moulding can be the goods of different material same color, or be the goods of identical material different colours, or be the goods of different colours different material, or be the goods composition of the identical material of same color.
Described injection mechanism can be the same platform of penetrating, and also can be comprised of a plurality of platforms of penetrating.
Beneficial effect of the present invention:
A kind of hollow injection molding forming method, can some need for the second time processing the hollow injection moulded products of band sealing, design is carried out in mould, oneself is final finished product to plastic parts when leaving die cavity, improve product assembly quality stability and cooperated compactness, saved manpower and materials.
