Thick-sectional part enclosed of the present utility model is used to be layered injection mold, it is achieved the layering injection of thick-sectional part, first
Configuration between the solid plate 210 and moving platen 220 of rotary table mould is needed to perform the intermediate plate 230 of revolving die core function, such as figure
Embodiment shown in 10, thick-sectional part enclosed layering injection molding operation comprises the following steps:
S10: utilize mechanical hand 300 to rotate intermediate plate 230, forwards the intermediate cavity 231 in cavity state to first station,
Being clamped between chamber 221, solid plate I chamber 211 and moving platen I, matched moulds constitutes product dispensable mould forming cavity；
S20: open the introduction valve of the first station, carries out the dispensable mould injection of product, and the dispensable mould that injection is formed stays centre
On chamber 231, form the intermediate plate 232 being loaded with product dispensable mould；As shown in figure 11.
S30: perform die sinking and pickup operation after temperature reaches die sinking temperature, will complete quadratic form note in previous injection cycle
The finished product moulded ejects from intermediate cavity 231；
S40: utilize mechanical hand 300 to rotate intermediate plate 230 and carry out turning core operation, and turning matched moulds after core puts in place: pickup
After operation, the intermediate cavity 231 in cavity state forwards the first station to, is clamped in chamber 221, solid plate I chamber 211 and moving platen I
Between, again constitute product dispensable mould forming cavity after matched moulds；Meanwhile, the intermediate plate 232 being loaded with product dispensable mould described in revolves
Forward the second station to, be clamped between chamber 222, solid plate II chamber 212 and moving platen II, again constitute after matched moulds and surround
Quadratic form forming cavity in product dispensable mould both sides；Figure 12 is that thick-sectional part enclosed of the present utility model is layered injection moulding process
Turn mold core action schematic diagram, this step utilizes mechanical hand 300 capture intermediate plate 230 and rotate, and carries out turning core operation,
Intermediate cavity 231 in cavity state and intermediate plate 232 transposition being loaded with product dispensable mould after pickup is operated.
S50: open the introduction valve of the second station, carries out the quadratic form injection of product, and high-temperature injection material is injected simultaneously into described
It is loaded with the both sides of the intermediate plate 232 of product dispensable mould, forms the quadratic form of enclosed structure；As shown in figure 13；
If all injection molding operation completes to go to step S60, otherwise returning step S20, circulation again and again carries out enclosed and divides
Layer injection is worked continuously；
S60: perform die sinking pickup operation after temperature reaches die sinking temperature, will complete the finished product of quadratic form injection from intermediate cavity
Eject in 231.
The forming principle of thick-sectional part enclosed of the present utility model layering injection moulding process is as it is shown in figure 5, use and be similar to " three
Mingzhi " injection molding manner, first in the core of the first station injecting products in dispensable mould injection moulding process, then use again
Enclosed of the present utility model layering injection moulding process, forwards the product dispensable mould formed in the first station injection to second station,
In quadratic form the injection moulding process simultaneously incidence surface of injecting products and exiting surface, i.e. reach three layers by twice injection and be molded
Effect.As a example by PC material, along with temperature T rises, density σ of PC material declines, for common PC material,
Fusing point is T=240 DEG C.Can there is condensate layer at filling process at nearly metallic walls in PC material, owing to plastics are the bad of heat
Conductor, usual die sinking temperature is set as the vitrification point (such as, 140 DEG C) of PC material, the now core temperature of product
Still can relatively be up to about 200 DEG C, form the core cooled down the most completely.After mould die sinking, plastics and air carry out heat exchange,
Dispensable mould 101 will present top layer and slowly solidify to core, and owing to PC is the non-conductor of heat, conduction process is the slowest.
The core of dispensable mould 101 due to cannot feeding, can cause in cooling procedure dispensable mould surface occur inhale flat.Open at mould
After mould, product dispensable mould 101 moves to the second station and carries out the injection of quadratic form, and injection mold uses Gao Mowen to ensure
Injection molding material is steadily filled, and the stream forward of injection molding material flows into and be full of quadratic form forming cavity, whole filling process such as Fig. 5 institute
Showing, the condensate layer 1032 formed with mould during quadratic form injection is fully fitted mould 210 and 220, the injection heat of quadratic form
Measure to heat the condensate layer 1011 of dispensable mould 101 and be melted into molten state, the condensate layer 1031 formed when being molded with quadratic form
Combine together, thus avoid the occurrence of product lamination.Meanwhile, quadratic form uses thin-walled property to process (relatively on wall thickness
For dispensable mould), it is ensured that injection moulding process is filled full.
According to the embodiment of thick-sectional part enclosed of the present utility model layering injection moulding process, described die sinking temperature is set as
The vitrification point of PC injection molding material.
According to the embodiment of thick-sectional part enclosed of the present utility model layering injection moulding process, the mould of quadratic form injection uses
Gao Mowen is to ensure the steady filling of injection molding material, and the flat depression of suction dispensable mould both sides occur can carry out feeding simultaneously.
According to the embodiment of thick-sectional part enclosed of the present utility model layering injection moulding process, the temperature of injection molding material to ensure two
The heating of dispensable mould condensate layer outer surface 1011 can be melted into molten state by the injection heat of secondary type, thus avoids the occurrence of product
Product lamination defect.
Thick-layer plastic uses the technique effect of enclosed of the present utility model layering injection moulding process and existing monolayer injection moulding process
Comparative result see table:
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to this utility model is described
Technical scheme, and be not used as to restriction of the present utility model, any based on connotation of the present utility model to
Go up change, modification that described embodiment is made, all will fall in scope of the claims of the present utility model.
