Under, then sizing material squeezes into 93 region of pellosil of workpiece 9 followed by upper cavity 851, lower chamber 852 from plastic squeeze runner 853
Glue-feeder, after 93 area filling of pellosil expires sizing material, extra sizing material and gas are arranged by extrusion channel 861 and exhaust cavity
Go out outside mold, advantageously ensure that the injection effect and injection moulding speed of workpiece 9, the quality of the workpiece 9 of production is high.
Remaining content of the present embodiment is same as Example 1, and which is not described herein again.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than the present invention is protected
The limitation of range is protected, although being explained in detail with reference to preferred embodiment to the present invention, those of ordinary skill in the art should
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
