In order to better make groove shaping loose core to loose core with fastening forming final together with outwards to have moved the demoulding, fastening forming is provided with the loose core spacing backing pin that coordinate shaping with groove on loosing core.
In order to improve security during Mould Machining, being provided with one group of resettlement groove, being mounted with safety spring in resettlement groove in slide block, this safety spring one end and moving platen fix, and the other end connects with slide block.
In order to improve the abrasion resistance of slide block, extend the mold use life-span, the auxiliary section of slide block and solid plate is also provided with adjustment block.
In order to 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, solid plate is provided with fixed die insert, moving platen is provided with moving die insert, between fixed die insert and moving die insert, be provided with die cavity.Block and slide block one-body molded.Oblique chute is T-slot or dovetail groove.
Beneficial effect of the present invention: adopt Angle Pin to loose core mode, 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 loose core backing pin that coordinate shaping with groove on loosing core, better make groove shaping loose core to loose core with fastening forming final together with outwards to have moved the demoulding; At the arranged outside stop screw of moving platen, between slide block and moving die insert, safety spring is set, improves security during Mould Machining; Further, be also provided with adjustment block in the auxiliary section of slide block and solid plate, improve the abrasion resistance of slide block, extend the mold use life-span.
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.
Detailed description of the invention
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, top clamping plate 1 is fixed with solid plate 2, this solid plate 2 is provided with fixed die insert 4, Bottom clamp plate 5 is fixed moving platen 6, this moving platen 6 is provided with moving die insert 18, between fixed die insert 4 and moving die insert 18, be provided with the die cavity 7 for injection mo(u)lding switch part; Described solid plate 2 is provided with Angle Pin 3, moving platen 6 is provided with slide block 8, slide block 8 is provided with the inclined hole coordinated with Angle Pin 3; Slide block 8 is provided with block 9, and near the side of die cavity 7, fastening forming is installed and looses core 10; Described fastening forming is loosed core on 10 and is arranged oblique chute 12, and this oblique chute 12 is preferably T-slot or dovetail groove, oblique chute 12 is mounted with groove is shaping looses core 11, and shaping the loosing core between 11 and block 9 of this groove is provided with stage clip 13.When mould die sinking, slide block 8 drive fastening forming loose core 10 laterally (right side namely in figure) motion, under the effect of stage clip 13, groove is shaping looses core and 11 to move downward along oblique chute 12, when the elastic force of stage clip overcomes that groove is shaping looses core active force downward, groove is shaping looses core and 11 outwards to move with slide block 8, departs from switch part, completes the demoulding.
In order to better make groove shaping loose core to loose core with fastening forming final together with outwards to have moved the demoulding, fastening forming is loosed core on 10 and is provided with the loose core 11 spacing backing pins 14 that coordinate shaping with groove, when groove is shaping loose core 11 move downward along oblique chute 12 time, run into backing pin 14 spacing after, groove is shaping looses core and 11 outwards to move with slide block 8, departs from switch part, as this improvement of the present invention, avoid the defect that stage clip long-term load easily lost efficacy, improve the reliability of mould.
In order to improve security during Mould Machining, being provided with one group of resettlement groove, being mounted with safety spring 15 in resettlement groove in slide block 8, this safety spring 15 one end and moving platen 6 fix, and the other end connects with slide block 8; Further, anti-limited slip block 8 is had to depart from the stop screw 17 of moving platen in the arranged outside of moving platen 6.
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 at slide block 8 and the auxiliary section of solid plate 2 adjustment block 16 be made up of high-abrasive material.
Preferably, described block 9 is one-body molded with slide block 8.
