Detailed description of the invention

Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.

A kind of special-shaped axis multimode combined die for forming, be described with direction shown in accompanying drawing 1 see shown in accompanying drawing, by relatively fastening upper die component and lower mold assemblies is formed, fasten in end face at upper die component and lower mold assemblies and form injection moulding die cavity 18, form corresponding workpiece after injecting the sizing of liquid material cooled, the present embodiment concrete structure is:

Upper die component comprises upper bolster 3, patrix Connection Block 4, upper padding plate 2 and cope match-plate pattern 1, upper bolster upper center is coaxially fixed with a patrix Connection Block and coaxially connects injection moulding head (not shown) by this patrix Connection Block, upper bolster lower end is fixed with upper padding plate and cope match-plate pattern from top to bottom successively, be shaped with injection molding channel 19 in this patrix, this injection molding channel is uniformly distributed to surrounding is planetary by center;

Lower mold assemblies comprises die shoe 14, lower bolster 13, lower bolster 12 and middle template 11, die shoe is packed on corresponding lathe base, die shoe upper end is fixed with lower bolster and lower bolster from bottom to top successively, the corresponding type groove be shaped with for the formation of injection moulding die cavity in the middle part of middle template and lower bolster.
