Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of mould for being molded helical blade shape workpiece.
Background technology
In prior art, the injection of helical blade shape workpiece produces, after in mould, injection helical member completes, if by spiral shell
Rotating part linearly ejects, and helical member can be damaged by the stop of mould, therefore can not directly take out, but needs note
Moulding workman to take out by hand, this greatly reduces work efficiency.
Summary of the invention
The present invention is directed to mould internal coiling injection-molded work in prior art and be not easily taken out of shortcoming, it is provided that be a kind of with spiral shell
The mould of ejecting mechanism after vane sheet moulding molding.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals:
A kind of with the mould of ejecting mechanism after helical blade moulding molding, including for helical blade workpiece injection mo(u)lding
Inner mould core, adventitia core, inner mould core is provided with spiral opening, and external mold in-core is provided with polygon die cavity, and outer core rod lower end is fixed with
Upper surface tooth, the lower section of upper surface tooth is fixed with lower surface tooth, and inner mould core, lower surface tooth are each attached on mould, described
Upper surface tooth and the laminating of lower surface tooth, lower surface tooth includes cooperation face and stop surface, and place, described cooperation face curved surface is a spiral
Curved surface, the helical angle in described cooperation face is identical with the helical angle of the spiral opening on inner mould core.
As preferably, outer core rod is fixed with gear, also includes tooth bar, pinion rotation described in described rack drives.
As preferably, also including oil cylinder, described oil cylinder band carry-over bar moves.
Due to the fact that and have employed above technical scheme, the moulding of helical blade shape is moved along leaf by external mold core ribbon
The angle of sheet spiral rotates, thus exits from inner mould core, improves work efficiency and will not damaged blade.

Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
A kind of with the mould of ejecting mechanism after helical blade moulding molding, as shown in Figures 1 to 5, including for helical-blade
The inner mould core 2 of sheet workpiece injection mo(u)lding, adventitia core 1, inner mould core 2 is provided with spiral opening 201, as shown in Fig. 5, Fig. 6, Fig. 7, outward
Being provided with polygon die cavity 101 in core rod 1, outer core rod 1 lower end is fixed with upper surface tooth 7, and the lower section of upper surface tooth 7 is fixed with
Lower surface tooth 5, inner mould core 2, lower surface tooth 5 be each attached on mould, and described upper surface tooth 7 is fitted with lower surface tooth 5, lower end
Face tooth 5 includes cooperation face 501 and stop surface 502, and place, described cooperation face 501 curved surface is a spiral camber, described cooperation face 501
Helical angle identical with the helical angle of the spiral opening 201 on inner mould core 2.It is fixed with gear 6 on outer core rod 1, also includes tooth
Bar 3, described tooth bar 3 drives described gear 6 to rotate.Also include that oil cylinder 4, described tooth bar 3 are connected on the piston cylinder of oil cylinder 4.
In the present embodiment, as shown in Figure 8, Figure 9, oil cylinder 4 band carry-over bar 3, gear 6 rotate, and drive adventitia core 1 to rotate,
Inner mould core 2 is owing to being integrally fixed on mould, thus without rotating.Owing to being provided with polygon die cavity 101 in outer core rod 1,
After workpiece has been molded, workpiece can produce the exterior angle being connected with helical blade, the polygonal die of exterior angle holding core rod 1 outside
In chamber 101, outer core rod 1 i.e. drives workpiece to rotate after rotating.Due to the helical angle coordinating face 501 on lower surface tooth 5 and interior mould
The helical angle of the spiral opening 201 on core 2 is identical, therefore when upper surface tooth 7 is in the sliding in the cooperation face 501 of lower surface tooth 5,
The movement locus of upper surface tooth 7 is identical with the helical angle coordinating face 501 on lower surface tooth 5, i.e. with the helical angle phase of helical blade
With.Therefore helical blade can exit from the spiral opening 201 of inner mould core smoothly along its hand of spiral.
After helical blade exits, the outer core rod 1 of rack drives rotates backward, and outer core rod 1 returns to initial position, carries out next
The individual working cycle.
In a word, the foregoing is only presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent
Change and modification, all should belong to the covering scope of patent of the present invention.
