The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 2 is the injection mold structure schematic diagram of band internal thread core height adjustment mechanism of the present utility model; Fig. 3 is an internal thread core height adjustment mechanism enlarged drawing of the present utility model.
See also Fig. 2 and Fig. 3, the injection mold of band internal thread core height adjustment mechanism of the present utility model comprises cover half die cavity 2, cover half core 3, dynamic model die cavity 4, internal thread core 5, ejector sleeve 6, thimble fixed head 7, top board 8, gripper shoe 9, gear 10, lining 11, screw thread guide 12, dynamic model pressing plate 14, fixed block 15, screw 16, cushion block 17, spring washer 18, wedge slide block 19, spring 20, push rod 21, cover plate 22.
Concrete connection is as follows: be provided with cover half core 3 in the cover half die cavity 2, be provided with internal thread core 5 in the dynamic model die cavity 4, the internal thread core 5 outer ejector sleeves 6 that are provided with, ejector sleeve 6 is fixed on the thimble fixed head 7, thimble fixed head 7 links to each other with top board 8, internal thread core 5 is outer to be provided with gear 10, is fixed with lining 11 on the dynamic model pressing plate 14, internal thread core 5 passes lining 11.The external screw thread of guiding is done in internal thread core 5 lower ends, and pitch is the same with the thread pitch of moulding.External screw thread is provided with screw thread guide 12 outward, and 6 jiaos of type counterbores are arranged at screw thread guide 12 bottoms, can be with the turn of 6 jiaos of type spanners.Screw thread guide 12 is fixed on the fixed block 15, and fixed block 15 is connected with cushion block 17 by screw 16.Screw thread guide 12 can not rotate when screw 16 screwed, and after screwing, screw thread guide 12 is locked.The gradient of 1～2 degree is done in cushion block 17 bottom surfaces.Cushion block has movably wedge slide block 19 for 17 times, and the end face gradient of wedge slide block 19 is the same with cushion block 17 bottom surface gradients.Be provided with spring washer 18 outside screw thread guide 12, on the fixed block 15, screw thread guide 12 drives the internal thread cores under the elastic force of spring washer 18 downward mobile trend, makes cushion block 17 fit with wedge slide block 19 all the time.Wedge slide block 19 1 ends are provided with spring 20, and the other end is provided with push rod 21, and push rod 21 1 ends have been done external screw thread.Push rod 21 is through in the dynamic model pressing plate 14.Wedge slide block 19 has cover plate, and cover plate 22 is fixing by screw and dynamic model pressing plate 14.In the assembling adjustment process, screw 16 does not screw earlier, with spanner rotation screw thread guide 12, adjusts the axial location of internal thread core 5, makes the height of its end face be lower than theoretical value slightly earlier.Screw 16 is being screwed locking screw guide 12 earlier.When wanting injection moulding to produce, mould is fixed on the injection machine, utilizes the high pressure mold clamping force of injection machine to compress active and inactive mold two parts.Change push rod 21 in choosing, promote wedge slide block 19, wedge slide block 19 withstands cushion block 17, fits up to abundant and cover half core 3 thereby raise internal thread core 5.Direction is rotated then, and internal thread core 5 reduces.Variation has taken place in the axial location as internal thread core 5 in the injection moulding production process, can directly rotate push rod 21 and adjust.
In sum, the injection mold that the utility model provides, drive the female type mandrel to moving by the fixing screw thread guide of axial rotary, to accomplish of the coarse regulation of female type mandrel earlier to the position, and then from mould side moving by the push rod drive wedge slide block on the rotation dynamic model pressing plate, and the variation of the axial location of the mobile drive female type core of wedge slide block, because the angle of wedge slide block is little, internally the axial location of thread core is done accurate adjustment, satisfies the injection moulding production requirement.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
