For the demoulding of outwards having moved together with better making groove moulding loose core to loose core finally with fastening forming, fastening forming is provided with the spacing backing pin of using of loosing core and coordinating with groove moulding on loosing core.
Security when improving Mould Machining, is provided with one group of resettlement groove in slide block, be mounted with safety spring in resettlement groove, and this safety spring one end and moving platen fix, and the other end and slide block join.
In order to improve the abrasion resistance of slide block, extend the service life of mould, the auxiliary section of slide block and solid plate is also provided with adjustment block.
For anti-limited slip block overexercise and break away from moulds laterally, the arranged outside of moving platen has anti-limited slip block to depart from the stop screw of moving platen.
Preferably, on solid plate, be provided with fixed die insert, on moving platen, be provided with moving die insert, between fixed die insert and moving die insert, be provided with die cavity.Block and slide block are one-body molded.Tiltedly chute is T-shaped groove or dovetail groove.
Beneficial effect of the present invention: adopt the Angle Pin mode of loosing core, utilize mould open/close mould power, under the effect of slide block and Compress Spring, complete and loose core, this having stable behavior of loosing core is reliable, and mould structure is simple, low cost of manufacture, difficulty of processing is not high simultaneously, has good practicality; Further, fastening forming is provided with the backing pin of loosing core and coordinating with groove moulding on loosing core, the demoulding of outwards having moved together with better making groove moulding loose core to loose core finally with fastening forming; Arranged outside stop screw at moving platen, arranges safety spring between slide block and moving die insert, the security while having improved Mould Machining; Further, in the auxiliary section of slide block and solid plate, be also provided with adjustment block, improve the abrasion resistance of slide block, extend the service life of mould.
Accompanying drawing explanation
Below with reference to drawings and Examples, the present invention is described in detail.
Structural representation when Fig. 1 is matched moulds of the present invention.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Structural representation when Fig. 3 is die sinking of the present invention.
The specific embodiment
Embodiment, see also Fig. 1 to 3, a kind of injection mould slide block demolding structure, comprise top clamping plate 1 and Bottom clamp plate 5, wherein, on top clamping plate 1, be fixed with solid plate 2, on this solid plate 2, be provided with fixed die insert 4, fixing moving platen 6 on Bottom clamp plate 5, is provided with moving die insert 18 on this moving platen 6, is provided with the die cavity 7 for injection mo(u)lding switch part between fixed die insert 4 and moving die insert 18; On described solid plate 2, Angle Pin 3 is installed, on moving platen 6, is provided with slide block 8, on slide block 8, be provided with the inclined hole coordinating with Angle Pin 3; On slide block 8, be provided with block 9, and near a side of die cavity 7, fastening forming be installed and loose core 10; Described fastening forming is loosed core on 10 oblique chute 12 is set, and this oblique chute 12 is preferably T-shaped groove or dovetail groove, tiltedly on chute 12, be mounted with groove moulding and loose core 11, this groove moulding loose core 11 and block 9 between be provided with stage clip 13.When mould die sinking, slide block 8 drives fastening formings 10 (i.e. right side in the figure) motions laterally of loosing core, under the effect of stage clip 13, groove moulding is loosed core and 11 along oblique chutes 12, is moved downward, when the elastic force of stage clip overcomes the active force that groove moulding looses core downward, groove moulding is loosed core and 11 with slide block 8, is outwards moved, and departs from switch part, completes the demoulding.
For the demoulding of outwards having moved together with better making groove moulding loose core to loose core finally with fastening forming, fastening forming loose core be provided with on 10 with groove moulding loose core 11 coordinate spacing with backing pins 14, when groove moulding looses core 11 when tiltedly chutes 12 move downward, run into backing pin 14 spacing after, groove moulding is loosed core and 11 with slide block 8, is outwards moved, and departs from switch part, as this improvement of the present invention, avoid the easily defect of inefficacy of stage clip long-term load, improved the reliability of mould.
Security when improving Mould Machining, is provided with one group of resettlement groove in slide block 8, be mounted with safety spring 15 in resettlement groove, and these safety spring 15 one end and moving platen 6 fix, and the other end and slide block 8 join; Further, the arranged outside at moving platen 6 has anti-limited slip block 8 to depart from the stop screw 17 of moving platen.
Because adopting Angle Pin, so in the process of folding mould, slide block 8 and solid plate 2 can produce larger frictional force, so be also provided with in slide block 8 and the auxiliary section of solid plate 2 adjustment block 16 of being made by high-abrasive material.
Preferably, described block 9 is one-body molded with slide block 8.
