But sink structure, including the die cavity main body being sequentially connected with and die cavity bottom, the outer peripheral face of die cavity main body are provided with the two of bottom connection
Individual spiral tank, one of spiral water groove top end are communicated with the first water inlet, and another spiral water groove top end is communicated with first
Delivery port, is provided with the restrictor ring being set on die cavity bottom between die cavity main body and die cavity bottom, the diameter of restrictor ring endoporus is more than mould
The external diameter of bottom of chamber correspondence position, restrictor ring are provided with the second water inlet and the second delivery port for connecting endoporus.
The restrictor ring material is lower-cost nylon, between die cavity bottom and die cavity main body, make die cavity bottom with
The sectional area S2 of cavity is reduced to S1 between die cavity main body, under equal water pressures, compared to in the cooling water channel of existing structure,
Die cavity bottom water flow velocity faster, so as to reach preferable cooling effect.
The section of the spiral tank processes spiral tank to be spherical, using ball cutter, the spherical tank of formation, can be with
Higher injection pressure is born, extends the service life of die cavity.
First water inlet, the first delivery port, the second water inlet and the second delivery port are communicated with a water pipe.
The utility model employs the sink structure of double helix, makes one group of cooling water channel of original structure into two groups of cooling waters
Road：The respectively independent cooling water road at the double helix water route of die cavity main body and die cavity bottom, shorten the stroke of cooling water channel, and spiral shell
The helicla flute of spin line formula is smaller to the resistance of water, and in the case of equal hydraulic pressure same time, the flow velocity of water faster, can be taken away
More heats；Die cavity bottom uses independent cooling water road, for cavity between die cavity bottom and die cavity main body sectional area S2 is excessive, mould
The problem of bottom of chamber cooling effect is bad, now using current limliting ring structure, material is lower-cost nylon, installed in die cavity bottom and mould
Between cavity main body, the sectional area S2 of cavity between die cavity bottom and die cavity main body is reduced to S1, under equal water pressures, compared to
In the cooling water channel of original structure, die cavity bottom water flow velocity faster, so as to reach preferable cooling effect
The beneficial effects of the utility model are：Cool time shortens, and die cavity bottom molding effect is preferable, improves production efficiency；
Double helix manufacturing procedure is relatively easy, reduces production cost；Spherical tank make it that die cavity service life is longer.
