Detailed description of the invention
Referring to figs. 1 through Fig. 2, a kind of injection mold embodiment for side forming through holes of the utility model is described further.
A kind of injection mold shaping for side through hole 13, a kind of injection mold with core-pulling mechanism, comprise the dynamic model base 1, mould pin 2, moving platen 3, solid plate 4, the cover half base 5 that set gradually, solid plate 4 is provided with core 6, moving platen 3 is provided with die cavity 7, core 6 and die cavity 7 abut the forming cavity 8 formed for product injection moulding.
Be provided with ejecting mechanism 21 between dynamic model base 1 and moving platen 3, ejecting mechanism 21 comprises push pedal, thimble fixed head, thimble and push rod, and thimble and push rod wear on core 6 end face along moving platen 3.
Moving platen 3 is provided with accommodating cavity 20 and the side core-drawing mechanism 9 being placed in this accommodating cavity 20 inside, side core-drawing mechanism 9 comprises compression assemblies 10 and releases assembly 11, there is between accommodating cavity 20 and forming cavity 8 through hole 13, releasing on assembly 11 is provided with for the shaping side core 12 of side direction through hole 13, and compression assemblies 10 compresses release assembly 11 and side core 12 is passed abutting on die cavity 7 inwall along through hole 13.
Release assembly 11 and comprise injection block 14, injection block 14 is provided with the first inclined-plane 16 be slidably matched with it towards compression assemblies 10 side, and injection block 14 and side core 12 are wholely set.
Compression assemblies 10 comprises crushing block 15, crushing block 15 is provided with the second inclined-plane 17 be slidably matched with the first inclined-plane 16, first inclined-plane 16 and the second inclined-plane 17 are in 45 degree of oblique cooperations, the cooperation on the first inclined-plane 16 and the second inclined-plane 17 can make both adopt the simplest mode to realize interlock, and ensures that the conversion of motion that compression assemblies 10 and release assembly 11 realize vertical direction is the motion of radial direction.
