Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-6, the present invention provides a technical solution: the utility model provides a processing injection mold of ply-yarn drill, which comprises a base 1, lower mould 6, cope match-plate pattern 2 and

last mould

5, 6 fixed mounting of lower mould is at the upside of base 1, go up the downside of mould 5 installation at cope match-plate pattern 2, still include push pedal 3 and thimble board 11, lower mould 6, it is equipped with relative die cavity 10 respectively to go up mould 5, swing joint has mould benevolence ejector pad 8 in the die cavity 10 of lower mould 6, fixed mounting has in the die cavity 10 of going up mould 5 lets position board 15, let the lower extreme of position board 15 and the butt joint of 8 looks adaptations of mould benevolence ejector pad, mould benevolence ejector pad 8, die cavity 10, let form the die cavity that is used for shaping ply-yarn drill between the position board 15, the locating piece 9 of two symmetries of upside both ends fixedly connected with of lower mould 6, locating piece 9 and the 5 looks adaptations joint of last mould after the compound die.

Push pedal 3 cup joints on base 1's upper portion and rather than swing joint, the middle part of push pedal 3 is equipped with the rectangular hole, the support of the both sides fixedly connected with L shape of lower mould 6, install release cylinder 4 down on the support, the piston rod and the push pedal 3 fixed connection of release cylinder 4, push pedal 3 passes through screw rod 7 and connects mould benevolence ejector pad 8, after the branch mould, the shrink of release cylinder 4 can promote mould benevolence ejector pad 8, make the both sides of injection molding not obstruct, make things convenient for the drawing of patterns.
