The technical solution adopted for the present invention to solve the technical problems is: a kind of injection mold with front mould tunnel loose core mechanism, comprise the panel, die block, die, solid punch, mould pin and the base plate that set gradually from top to bottom, be embedded with slide block one and Angle Pin fixed block in gap between described die block and die, described Angle Pin fixed block be installed with the Angle Pin that can slide with movable slider one, described injection mold also has two groups of front mould tunnel loose core mechanisms, the described front mould tunnel loose core mechanism that often organizes comprises loose core oil cylinder and the limited block of loosing core that are fixedly mounted on respectively on die block sidewall, what be fixedly mounted on limited block upper surface of loosing core tiltedly carves fixed block, be slidably connected at and tiltedly carve tiltedly carving on the left of fixed block, be slidably connected at loose core contiguous block and the body of loosing core that is plugged on the left of contiguous block of loosing core of tiltedly carving left side, described top of tiltedly carving snaps onto the bottom of the piston rod of oil cylinder of loosing core, described body of loosing core realizes the action heading into slide block one or extract slide block one out under the driving of oil cylinder of loosing core.
Further, the right side of the upper surface of solid punch described in technique scheme is installed with slide block two, and the top left-hand thread of described slide block two has slider locking block.
Further, the upper surface of base plate described in technique scheme is disposed with push pedal and ejector retainner plate from the bottom up, and the upper surface of described ejector retainner plate is provided with several thimbles; Also support column is provided with between described solid punch and base plate.
The invention has the beneficial effects as follows: the injection mold with front mould tunnel loose core mechanism of the present invention, simple and compact for structure, good stability, it is smooth and easy that front mould tunnel loose core mechanism can realize mold actions, registration, saves time, thus reduces the production cycle of mould, it is more competitive that the optimization of each side such as ordinary maintenance and lifting improve the goods that mould is produced, more can reduce the waste of the energy, compared with ordinary injection die, output more than 70% can be improved.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The injection mold with front mould tunnel loose core mechanism as shown in Figure 1, comprise the panel 7, die block 8, die 9, solid punch 13, mould pin 14 and the base plate 18 that set gradually from top to bottom, be embedded with slide block 1 and Angle Pin fixed block 11 in gap between die block 8 and die 9, Angle Pin fixed block 11 be installed with the Angle Pin 12 that can slide with movable slider 1.Wherein, the right side of solid punch 13 upper surface is installed with slide block 2 20, and the top left-hand thread of slide block 2 20 has slider locking block 19.The upper surface of base plate 18 is disposed with push pedal 17 and ejector retainner plate 16 from the bottom up, and the upper surface of ejector retainner plate 16 is provided with several thimbles 21; Support column 15 is also provided with between solid punch 13 and base plate 18.
As Fig. 1, shown in Fig. 2 and Fig. 3, injection mold also has two groups of front mould tunnel loose core mechanisms, often organize front mould tunnel loose core mechanism and comprise loose core oil cylinder 1 and the limited block 6 of loosing core that are fixedly mounted on respectively on die block 8 sidewall, what be fixedly mounted on limited block 6 upper surface of loosing core tiltedly carves fixed block 5, be slidably connected at tiltedly to carve and tiltedly carve 4 on the left of fixed block 5, be slidably connected at loose core contiguous block 3 and the body 2 of loosing core that is plugged on the left of contiguous block 3 of loosing core tiltedly carved on the left of in the of 4, the top of tiltedly carving 4 snaps onto the bottom of the piston rod of oil cylinder 1 of loosing core, body 2 of loosing core realizes the action heading into slide block 1 or extract slide block 1 out under the driving of oil cylinder 1 of loosing core.
As shown in Figure 1, front mould tunnel loose core mechanism is mainly divided into three groups of actions to realize the front mold core-pulling of mould according to sequence of movement, and setting initial actuating is matched moulds state, shown in three groups of actions are specific as follows:
Set: before injection moulding machine mould open, oil cylinder 1 of loosing core drives tiltedly to carve on 4 and moves, be connected by oblique T slide with contiguous block 3 of loosing core owing to tiltedly carving 4, therefore while tiltedly carving and moving on 4, body 2 of loosing core all moves right under the drive of oblique T guide rail with contiguous block 3 of loosing core, and the left end of body 2 of namely loosing core exits from slide block 1;
Second group of action: loose core and deviate from after back-off completely, the normal die sinking of mould;
3rd group of action: after mould matched moulds, oil cylinder 1 oil-feed of loosing core ejects, and oil cylinder 1 of loosing core drives tiltedly to be carved 4 and move down, tiltedly carve 4 move down while drive loose core body 2 and contiguous block 3 of loosing core all to be moved to the left, the left end of body 2 of namely loosing core heads in slide block 1.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
