For overcome the deficiencies in the prior art, the utility model provides a kind of special-shaped shell body injection mold
Technical solution is used by the utility model solves its technical problem：
Special-shaped shell body injection mold, including preceding mould, rear mold, preceding core rod and rear core rod, it is characterised in that：On the preceding core rod
Equipped with preceding formed body, it is described after core rod be equipped with and protrude from aftershaping body, sliding slot and the embedding piece groove of rear core surface, it is described after into
Type body is equipped with forming tank, and being equipped with the sliding slot can be in the sliding block slided in sliding slot, which is equipped with being capable of insert molding
The shaping column of groove and the ramp-roof structure that can be moved back and forth with movable slider, the embedding piece groove are embedded with manual mold insert, this is manual
Mold insert is equipped with forming ring, and the aftershaping body is equipped with forming hole, and the manual mold insert is equipped with being capable of insert molding hole
Forming core, the aftershaping body is equipped with some slide openings, the thimble being connected with push plate is equipped with the slide opening.
The slot bottom of the sliding slot is opposite to be equipped with two boss, and latch segment, and the bottom surface of latch segment and boss are provided with boss
Side and slot bottom surround a sliding slot, sliding block bottom is equipped with the draw runner coordinated with sliding slot.
Inclined guide pillar before the ramp-roof structure includes the oblique guide hole being arranged on sliding block and is arranged on core rod is described oblique
Guide post is located in oblique guide hole and is slidably matched with oblique guide hole.
The beneficial effects of the utility model are：The utility model is integrally ejected using manual mold insert and the product after injection
Structure, then column that runner is formed is removed using instrument and separates manual mold insert with product manually again, so
Hot-fluid need not be set to lead device, not only reduce the complexity of mould, and the manufacture cost of mould is low.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the explosive view of the utility model；
Fig. 2 is the topology view of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of special-shaped shell body injection mold, including preceding mould 1, rear mold 2, preceding mould
Core 3 and rear core rod 4, the preceding core rod 3 are equipped with preceding formed body, and the rear core rod 4 is equipped with after protruding from rear 4 surface of core rod
Formed body 5, sliding slot 6 and embedding piece groove 7, the aftershaping body 5 are equipped with forming tank 9, and being equipped with the sliding slot 6 can be in sliding slot 6
The sliding block 8 of slip, the sliding block 8 be equipped be capable of insert molding groove 9 shaping column 10 and can with movable slider 8 move back and forth
Ramp-roof structure, the embedding piece groove 7 are embedded with manual mold insert 11, which is equipped with forming ring 12, and the aftershaping
Body 5 is equipped with forming hole 13, and the manual mold insert 11 is equipped with the forming core for being capable of insert molding hole 13（Do not shown in figure）,
The aftershaping body 5 is equipped with some slide openings 14, and the thimble 16 being connected with push plate 15 is equipped with the slide opening 14.
The slot bottom of the sliding slot 6 is opposite to be equipped with two boss 17, and latch segment 18, and the bottom of latch segment 18 are provided with boss 17
Face surrounds a sliding slot 6 with the side of boss 17 and slot bottom, and 8 bottom of sliding block is equipped with the draw runner 19 coordinated with sliding slot 6；The oblique top knot
Inclined guide pillar 21 before structure includes the oblique guide hole 20 being arranged on sliding block 8 and is arranged on core rod 3, the inclined guide pillar 21 is positioned at oblique
It is slidably matched in guide hole 20 and with oblique guide hole 20.
In said structure, preceding formed body closes up with aftershaping body 5 after molding, forms the main forming cavity of product 22, product
22 main bodys are made of two vertical housings one and housing two, housing one be arc-shaped and it is interior have groove, have ring-like back-off on cell wall,
Forming ring 12 is embedded in forming cavity, so as to be molded by ring-like back-off on product 22, is noted by forming core on housing one
Modeling, which is portalled, to be come, and the column that honeycomb duct is formed is located among housing one, and also is located among forming ring 12, and manual mold insert
11 are equipped with the forming core for being capable of insert molding hole 13, thus column is not cut off, and forming ring 12 cannot depart from from product 22.
