State and on the right side of liftout plate 4, be fixed with return spring 5, described in eject base plate 3 and liftout plate about 4 both sides are provided with push rod 6, described cover half
Fixed plate 7 it is provided with on the right side of main body 1；Core rod 8, described core rod 8 includes: threeway core rod I 9, threeway core rod II 10 and threeway core rod III
11, described threeway core rod I 9 is arranged on cover half main body 1 inner right side, and it is internal that described threeway core rod II 10 is arranged on cover half main body 1
Left side, described threeway core rod III 11 is arranged on cover half main body 1 upper inside, is provided with dividing plate 81 in described core rod 8；Upper mold 12, institute
Stating upper mold 12 to be respectively provided on described threeway core rod I 9, threeway core rod II 10 and threeway core rod III 11, described upper mold 12 is provided with
Water inlet 13 and outlet 14, be provided with cylinder 15 between described water inlet 13 and outlet 14；Die cavity 16, described die cavity 16 wraps
Including: die cavity I 161 and die cavity II 162, described die cavity I 161 is arranged on described threeway core rod I 9 and threeway core rod III 11 is internal, institute
Stating die cavity II 162 and be arranged on described threeway core rod II 10 inside, described die cavity II 162 is internal is provided with middle mold 17, water column 18 and mould
Set 19；Lower mold 20, described lower mold 20 is arranged on the downside of upper mold 12, and is provided with screw 21 between upper mold 12 and lower mold 20.
A kind of threeway injection mold of the present invention, for threeway core rod I 9 and threeway core rod III 11, is inserted by dividing plate 81
In core rod 8, it may be preferable that the upper surface of lower mold radially end face is evenly arranged with multiple mounting hole, and specially 6, dividing plate divides
In mounting hole, and then each mounting hole Cha Ru not formed two water cavities, dividing plate side is intake antrum, and dividing plate opposite side is water outlet
Chamber, similarly, middle mold upper surface radially end face is evenly arranged with multiple mounting hole, specially 5, but these 5 mounting holes
With 6 mounting hole interlaced arrangement of lower mold, one of them mounting hole part of middle mold is just made to cover a waist of lower mold
Shape hole, meanwhile, also covers another mounting hole that this mounting hole of lower mold is adjacent, so so that cooling water entering through middle mold
Water hole enters in the intake antrum of lower mold, under extraneous hydraulic pressure effect, then returns to middle mold upper surface, subsequently enters in another
Mounting hole on mould, and then be again introduced in the intake antrum of adjacent mounting hole of lower mold, the most alternately reciprocation cycle, meanwhile,
Being provided with middle mold inlet opening 171 and middle mold apopore 172 in middle mold, so, cooling water is through the water inlet of upper mold, in middle mold
Mould inlet opening, flows in the intake antrum of lower mold then, through water chamber, middle mold apopore and upper mold outlet, circulation is integrally formed
Process, fixes with upper mould 12 with 4 M10 × 80 screws 21, so can improve fixed effect, by the φ 10 of upper mold 12
Hole ensure that water circulates in core rod 8 as water inlet 13 and outlet 14, outside has the cooling water channel of whole die cavity 16 to enter
Row cooling so that uniformly, for threeway core rod II 10, described 6 dividing plates 81 insert 6 water columns of lower mold 20 respectively in product cooling
In 18, die sleeve 19 inserts in lower mold 20, it is ensured that die sleeve 19 centrage is consistent with lower mold 20 die cavity 16 centrage, under middle mold 15 loads
In the groove of mould 20, water column 18 is loaded in die sleeve 19, with 4 M10 × 80, lower mold 20 and upper mold 12 are fixed.By upper mold 12
As water inlet 13 and outlet 14, the hole of φ 10 ensures that water circulates in die cavity 16, have water column 18 to cool down in product piece,
There are outward 6 water channel coolings, have cold water to cool down inside and outside such moulding, it is ensured that the cooling of product is uniform, thus ensures simultaneously
The stability of injecting products part size.
The work process of the present embodiment is, by being injected in core rod 8 by melted injection molding material, is carried out at pressurization by cylinder 15
Reason, water inlet 13 and outlet 14 access water supply line respectively, will eject base plate 3 He on the right side of cover half main body 1 upper plate main body 2
Liftout plate 4 is operated under the effect of return spring 5, after carrying out a series of injection in core rod 8, and water inlet 13 and outlet 14
Interior water carries out cooling by water column 18 to injecting products in die cavity 16 and circulates, thus reaches to cool down the most even injecting products part size
Stable purpose.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
