Embodiment
For ease of it will be understood by those skilled in the art that the technical solution of the utility model, below by technology of the present utility model
Scheme is described in further detail in conjunction with specific embodiments.
Such as Fig. 1, a kind of injection mold includes cavity plate 20 and sprue, the cavity plate 20 be provided with multiple runners and
Multiple die cavities；Below by taking six runners and six die cavities as an example：First runner 261, the shunting of the second runner the 262, the 3rd
Road 263, the 4th runner 264, the 5th runner 265 and the 6th runner 266；First die cavity 231, the second die cavity the 232, the 3rd
Die cavity 233, the 4th die cavity 234, the 5th die cavity 235 and the 6th die cavity 236；The multiple die cavity is distributed in the circumference of same circle
On；The multiple runner center of circle of circle where multiple die cavities extends to corresponding die cavity, the multiple runner length phase
Deng, and in same level；Ensure that stream the material pressure loss and thermal loss in each runner are equal, it is various so as to ensure
Injecting products uniformity in chamber；Consequently facilitating the temperature and injection pressure of controlling stream material, so as to ensure the qualification rate of injecting products；
Sprue circle centre position of circle where multiple die cavities connects with runner, and sprue and runner connectivity part are connector
21, the sprue is arranged vertically；The one end of the multiple runner away from corresponding die cavity connects with sprue；Stream material is through main flow
Road, to each runner component and partial pressure at connector 21, so as to ensure the stream material pressure and stream material heat in a runner
Loss is consistent；Consequently facilitating the temperature and injection pressure of controlling stream material, so as to ensure the qualification rate of injecting products；Be advantageous to be molded
Middle stream material Uniform Flow, reduces each runner pressure loss, so as to meet to propose large-duty requirement using multiple die cavities
Under, ensure qualification rate.
The multiple die cavity is arranged on same level；Be advantageous to stream material Uniform Flow in runner, reduce stream material and exist
In runner because of pressure and thermal loss and caused by disqualification rate.
The multiple die cavity is provided with cold slug well, and corresponding cold slug well is consistent with die cavity quantity, a die cavity corresponding one
Individual cold slug well, the cold slug well are six, the first cold slug well 241, the second cold slug well 242, the 3rd cold slug well 243, the 4th cold burden
Cave 244, the 5th cold slug well 245 and the 6th cold slug well 246；The cold slug well is advantageous to stream material entering die cavity away from runner
Preceding material enter cold slug well, so as to more preceding material and injecting products will separate as far as possible, expect to enter injecting products before preventing, cause to note
Molding product qualification rate is low；The preceding material in cold slug well is cut off after injection formed.
The injection mold also includes multiple cores；The die cavity is provided with shoulder hole, and one die cavity is corresponding one
Shoulder hole, shoulder hole is six herein, the first shoulder hole 271, the second shoulder hole 272, the 3rd shoulder hole 273, fourth order ladder hole
274th, the 5th shoulder hole 275 and the 6th shoulder hole 276；The multiple core is respectively arranged with boss；Core and die cavity coordinate, institute
The shoulder hole for stating boss and corresponding die cavity coordinates；Coordinated with boss and shoulder hole, advantageously ensure that core and die cavity cooperation position,
So as to ensure that the qualification rate of injecting products.
The injection mold also includes guide pillar；The cavity plate 20 is provided with multiple guide pin bushings, guide pin bushing setting herein four, the
One guide pin bushing 251, the second guide pin bushing 252, the 3rd guide pin bushing 253 and the 4th guide pin bushing 254；The multiple guide pin bushing is symmetrically and evenly arranged, described
Multiple guide pin bushings coordinate with guide pillar respectively；Ensure 20 uniform force in use of cavity plate, ensure the qualification rate of injecting products.
Above is preferred embodiment of the present utility model, is not used in restriction the scope of protection of the utility model.This area
Technical staff is after it understanding of the technical solution of the utility model, the non-creativeness deformation and change made, it should fall within this
The protection domain of utility model.
