Fig. 1 is the structural representation of the injection mold that provides of the utility model embodiment.

Fig. 2 is the structural representation of the cover half of the injection mold in Fig. 1.

Fig. 3 is the structural representation of the dynamic model of the injection mold in Fig. 1.

The specific embodiment

Please refer to Fig. 1 to Fig. 3, a kind of injection mold that the utility model embodiment provides, it comprises cover half and the dynamic model matched with cover half.

Please refer to Fig. 2, cover half comprises top clamping plate 11 and solid plate 12.Top clamping plate 11 and solid plate 12 all are roughly square platy structure.Solid plate 12 is fixed on top clamping plate 11.

Please refer to Fig. 3, dynamic model comprises Bottom clamp plate 14, moving platen 16, two gripper shoes 15 and push pedals 17.Bottom clamp plate 14, moving platen 16 and push pedal 17 are the square plate structure.One end of two gripper shoes 15 is fixed on Bottom clamp plate 14, and the interval preset distance.Moving platen 16 is fixedly connected with the other end of two gripper shoes 15.Push pedal 17 is arranged between Bottom clamp plate 14, moving platen 16 and two gripper shoes 15 movably, is provided with a plurality of (not shown) of the push rod towards moving platen 16 in push pedal 17, for the parts by after moulding, ejects.

Be provided with the first die cavity 122, the second die cavity 123 and the 3rd core 124 on solid plate 12.The first die cavity 122 and the second die cavity 123 are with respect to the upper surface indent of solid plate 12, and the 3rd core 124 is with respect to the upper surface evagination of solid plate 12.Be provided with the first core 162, the second core 163 and the 3rd die cavity 164 on moving platen 16.The first core 162 and the second core 163 are with respect to the upper surface evagination of moving platen 16, and the 3rd die cavity 164 is with respect to the upper surface indent of moving platen 16.The first core 162, the second core 163 and the 3rd core 124 match with the first die cavity 122, the second die cavity 123 and the 3rd die cavity 164 respectively.The degree of depth of the 3rd die cavity 164, the second die cavity 123 and the first die cavity 122 increases progressively.
