In the present embodiment, driving acting cylinder 71 above-mentioned is oil cylinder, but cylinder can also be used, and electronic ruler 74 above-mentioned is
Linear displacement transducer.
Shown in foundation Fig. 6, into three color plastic melts in three color plastic melt diversion cavity 41 of shunting disk seat successively through leading
Stream set melt flow channel 651 and three color plastic melt runners 641 simultaneously introduce hollow plastic from three color plastic melt runner discharge ports 6411
In the mold of material products molding machine, formed by inflation forming machine structure inflation.
As a preferred option, a compression can also be arranged on the spreader disk 21 of the structural system of aforementioned material receiving mechanism 2
Air introduction 229, the compressed air introduce pipe 229 successively by way of i.e. across spreader disk 2 aforementioned main plastic melt outside lead
Diversion trench 224 is communicated with the water conservancy diversion subcenter hole 234 of aforementioned die head inner core water conservancy diversion 23 in chute 225 and main plastic melt,
Company into the compressed air in the water conservancy diversion subcenter hole 234 of die head inner core water conservancy diversion 23 through die head inner core reinforcement connecting screw 83
The mold core centre bore 642 that pitch hole 831 leads to mold core 64 is connect, then is drawn compressed air by mold core centre bore 642, is compressed
The effect of air is to prevent plastic melt from generating adhesion, improves the regular consistency of the shape of melt base.
Fig. 7 is referred to, by three color plastic melt bases in the mold of present invention supply said hollow plastic product molding machine
Outer wall surface after the molding of inflation forming machine structure inflation in hollow plastic product forms equally distributed first color fringe 30a
With the second color fringe 30b.
As long as by the above description of applicant it is found that under the inspiration of the present invention to material receiving mechanism 2 and diversion mechanism 3
Structure slightly simple change can achieve the purpose that increase or decrease colour bar line.
Since transparent liquid level line material feed mechanism 5 belongs to the prior art, thus applicant repeats no more.But it requires emphasis
It is: when production has hollow plastic product (i.e. the container) of transparent liquid level line, the first of the structural system of aforementioned feeding machanism 1
Colored plastic melt conveying connector 11 and the second colored plastic melt conveying connector 12 are in stopping conveying color modeling
Expect the state of melt, the state for conveying main plastic melt is only in by main plastic melt conveying connector 13.
In conclusion technical solution provided by the invention compensates for the shortcoming in prior art, invention has been favorably accomplished
Task has faithfully fulfilled the technical effect that applicant refers in technical effect column above.
