Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Mode, the utility model is further elaborated.
The utility model first embodiment provides a kind of tee pipe fitting injection forming mold, for institute as shown in Figure 1, Figure 2
Show that tee pipe fitting 1 carries out injection molding, it is necessary to which explanation, it is exemplary knot that the tee pipe fitting shown in Fig. 1, Fig. 2, which is only,
Structure, restriction effect is not played to injection forming mold of the present utility model and core.
As shown in Figure 3, Figure 4, the injection forming mold of the present embodiment includes cover half 2 and dynamic model 3, and the cover half 2 includes the
One die cavity 21, the dynamic model 3 include the second die cavity 31, after the dynamic model 3 and cover half matched moulds, the first die cavity 21 and the second die cavity 31
Docking forms the injection die cavities for being used for being molded the tee pipe fitting 1;The injection mold of the present embodiment also includes injection core, described
Injection core is in the injection die cavities.
Further, the injection core includes being for respectively forming first core 4 of 1 three tube chambers of tee pipe fitting, the
Two cores 5 and the 3rd core 6, during injection, first core 4, the second core 5 and the 3rd core 6 dock two-by-two;Described first
Core 4 includes the first projection 41 positioned at docking one end, and the core 6 of the second core 5 and the 3rd is respectively equipped with docking one end
