Detailed description of the invention
Shown in Fig. 1-Fig. 7, a kind of injection mold entering glue in slide block inside, comprise dynamic model frame 1, cover half frame 2, liftout attachment, formed product region is formed between dynamic model frame 1 and cover half frame 2, the mavable module core 3 be fixed on dynamic model frame 1 is provided with in formed product region, the right side of mavable module core 3 is provided with the first slide block 5 and the second slide block 6, mavable module core 3 and cover half frame 2 inwall, formed product chamber 4 is formed between on the left of first slide block 5 and on the left of the second slide block 6, the right side of mavable module core 3 and form product 17 back side die cavity between the first slide block 5 and the second slide block 6, the described horizontal activity of the second slide block 6 is engaged in the first slide block 5, laterally material road 7 is provided with between second slide block 6 and the first slide block 5, laterally the inner in material road 7 is communicated with formed product chamber 4, laterally be provided with vertical material road 8 above material road 7, vertical material road 8 is located on cover half frame 2, the first described slide block 5 and the second slide block 6 are provided with and the first slide block 5 can be made to expect road 7 with the second slide block 6 with horizontal and vertically expect the releasing mechanism that road 8 is separated.
Be provided with laterally material road 7 between second slide block 6 and the first slide block 5 to refer to and be laterally provided with a groove 6.1 on the left of the second slide block 6 upper surface, between groove 6.1 and the first slide block 5, form laterally material road 7.
Described cover half frame 2 is provided with sprue bush 9, and vertical material road 8 is located in sprue bush 9, and it is inner that sprue bush 9 is inserted into the first slide block 5 downwards, vertically expects road 8 and laterally expects that road 7 is connected.
The described horizontal activity of the second slide block 6 is engaged in the first slide block 5 elastic parts 10 referring to and to be provided with between the second slide block 6 and the first slide block 5 and to realize the transverse movement to the right of the second slide block 6.
The first described slide block 5 is provided with the limited post 5.4 that prevents the second slide block 6 slippage first slide block 5 in the below of elastic parts 10.
Described elastic parts 10 is helical spring.
The first described slide block 5 and the second slide block 6 are provided with and the first slide block 5 can be made to expect road 7 and vertically expect that the releasing mechanism that road 8 is separated refers to that the first slide block 5 coordinates through slant rail with cover half frame 2 have movable room 11 between the right side of the first slide block 5 and the second slide block 6 and cover half frame 2 with the second slide block 6 with horizontal; Form ramp 11.1 and lower inclined plane 11.2 in the cover half frame 2 at movable room 11 place, ramp 11.1 angle of inclination is less than lower inclined plane 11.2 angle of inclination, and right-hand member and the ramp 11.1 of the second slide block 6 offset; Be formed between lower inclined plane 11.2 and movable room 11 when cover half frame 2 moves upward and be convenient to the second slide block 6 strokes of regions slipped into; The first described slide block 5 lower end is provided with a pulling block 5.1, and left side and mavable module core 3 lower surface of pulling block 5.1 vertically interlock, and have infeed stroke chamber 12 between the right side of pulling block 5.1 and dynamic model frame 1; Laterally be 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, is provided with the step 5.2 be convenient to limited block 13 when limited block 13 moves upward and driven the first slide block 5 to move upward on the right side of the first slide block 5 above limited block 13.
First slide block 5 and cover half frame 2 coordinate through slant rail and refer to and obliquely on the first slide block 5 be provided with T-shaped slide block 5.3, and T-shaped slide block 5.3 slide block is that right side tilts to the left, obliquely in cover half frame 2 are provided with the T-shaped guide rail 2.1 coordinated with T-shaped slide block 5.3.
Be provided with cover half panel 14 outside described cover half frame 2, cover half panel 14 is encircled on cover half frame 2.
Described liftout attachment comprises top board 15 and thimble 16, and thimble 16 is from bottom to top once through dynamic model frame 1, mavable module core 3.
Operation principle of the present invention is: injection machine by the plastic injection of melting state in sprue bush 9, liquid plastic flows in the first slide block 5, transverse direction 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, position, formed product chamber 4 becomes product 17, shot process.
As shown in Figure 3, during die sinking, cover half part and dynamic model part will 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 slides along oblique T-shaped guide rail 2.1, because 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, in the process of the first slide block 5 oblique movement, second slide block 6 of the first slide block 5 inside also and then moves together, ramp 11.1 is departed from the right side of the second slide block 6, when propping up lower inclined plane 11.2 arrival activity room 11, second slide block 6 to be turned right motion by the effect of elastic parts 10, until solid plate 2 is encountered simultaneously in the right side of the second slide block 6, the right-hand member of the second slide block 6 is also blocked by the limited post 5.4 on the first slide block 5.Stub bar is by the pulling function disengaging sprue bush 9 of the first slide block 5 in the process of moving upward for cover half frame, and when the 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 model cover half continues separately, and stub bar is separated with cover half part together with product 17, encounters the first slide block 5 (as shown in Figure 6) on the downside of stub bar, and stub bar pulls 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 product 17 is ejected mavable module core 3 by the thimble 16 on top board 15.
