Described cover half frame 2 is provided with sprue bush 9, and vertical material road 8 is located in sprue bush 9, sprue bush 9
Being inserted downwardly into the first slide block 5 internal, vertical material road 8 is connected with laterally material road 7.
The second described laterally movable cooperation of slide block 6 refers to the second slide block 6 and first in the first slide block 5
The elastic parts 10 realizing the second slide block 6 transverse movement to the right it is provided with between slide block 5.
The first described slide block 5 is provided with one and prevents the second slide block 6 from slipping in the lower section of elastic parts 10
The limited post 5.4 of one slide block 5.
Described elastic parts 10 is helical spring.
The first described slide block 5 and the second slide block 6 are provided with and can make the first slide block 5 and the second slide block 6
The releasing mechanism separated with laterally material road 7 and vertical material road 8 refers to that the first slide block 5 and cover half frame 2 are through tiltedly
Guide rail coordinates, and has movable room 11 between the first slide block 5 and the right side of the second slide block 6 and cover half frame 2；
Forming ramp 11.1 and lower inclined plane 11.2 in cover half frame 2 at movable room 11, ramp 11.1 inclines
Rake angle is less than lower inclined plane 11.2 angle of inclination, and the right-hand member of the second slide block 6 offsets with ramp 11.1；
It is formed at when cover half frame 2 moves upward between lower inclined plane 11.2 and movable room 11 and is easy to the second slide block 6
Draw the region slipped into；The first described slide block 5 lower end is provided with a pulling block 5.1, and the left side of pulling block 5.1 is with dynamic
Die 3 lower surface vertically interlocks, and has infeed stroke chamber 12 between right side and the dynamic model frame 1 of pulling block 5.1；
Being transversely provided with stroke limit block 13 on the right side of first slide block 5, limited block 13 is fixed on cover half frame 2, and first
On the right side of slide block 5 limited block 13 be arranged over when limited block 13 moves upward be easy to limited block 13 and carry
The step 5.2 that dynamic first slide block 5 moves upward.
First slide block 5 and cover half frame 2 coordinate through slant rail and refer to oblique on the first slide block 5 be provided with T-shaped cunning
Block 5.3, T-shaped slide block 5.3 slide block is that right side tilts to the left, oblique in cover half frame 2 is provided with and T-shaped cunning

Frame 1, mavable module core 3.
The operation principle of the present invention is: injection machine by the plastic injection of melting state in sprue bush 9, liquid
Plastics flow in the first slide block 5, the laterally material road 7 between the first slide block 5 and the second slide block 6, finally
Flow to the formed product chamber 4 between cover half frame 2 and mavable module core 3, after filling full cavity, 4, formed product chamber
Put and become product 17, shot process.
As it is shown on figure 3, during die sinking, cover half part and dynamic model part to be separated, and cover half frame 2 moves upward,
Owing to coordinating through slant rail between the first slide block 5 and cover half frame 2, so the first slide block 5 T-shaped is led along oblique
Rail 2.1 slides, owing to the pulling block 5.1 of the first slide block 5 lower end is held, the first slide block 5 can only transverse shifting,
Until the first slide block 5 encounters limited block 13, pulling block 5.1 departs from mavable module core 3, the just stop motion of the first slide block 5；
As shown in Figure 5 and Figure 6, during the first slide block 5 oblique movement, within the first slide block 5
Two slide blocks 6 also and then move together, depart from ramp 11.1, prop up lower inclined plane 11.2 on the right side of the second slide block 6
During arrival activity room 11, the second slide block 6 is turned right motion by the effect of elastic parts 10, until the second slide block
Solid plate 2 is encountered simultaneously in the right side of 6, and the right-hand member of the second slide block 6 is also kept off by the limited post 5.4 on the first slide block 5
Live.Cover half frame stub bar during moving upward is departed from sprue bush 9 by the pulling function of the first slide block 5, when
When second slide block 6 reaches movable room 11 to the right, the stub bar on the second slide block 6 departs from the second slide block 6；Dynamic
Mould cover half continues separately, and stub bar is partially separated with cover half together with product 17, encounters first sliding on the downside of stub bar
Block 5 (as shown in Figure 6), stub bar is pulled by product 17, and stub bar deformation tilt skids off the first slide block 5, completes
The stripping movement of stub bar；The top rod of last injection machine promotes top board 15, and the thimble 16 on top board 15 will produce
Product 17 eject mavable module core 3.
