The utility model discloses shortened threaded core move back the screw thread time, work efficiency is higher.
Description
Technical field
This utility model belongs to injection molding technology field。
Background technology
Injection mold is a kind of instrument producing plasthetics, is also to confer to the instrument of plasthetics complete structure and accurate dimension。Its occupation mode is to be injected in the die cavity of injection mold by the material high pressure melted that is heated, and after cooled solidification, obtains formed products。When existing moulding needs to manufacture screw thread, it is necessary to put into thread core in injection mold, after completing injection moulding, threaded moulding is deviate from。
But owing to threaded moulding and thread core are in the state of threaded engagement, so to deviate to need first to be exited along its screw thread rotation from injection molding cavity by thread core by moulding after die sinking, the mode of current thread core Leave out thread mainly adopts and manually turns thread core, thread core is exited from the threaded portion of moulding, the mode of this Leave out thread is consuming time longer, inefficiency。
Utility model content
This utility model is intended to provide rotation short, that work efficiency is high consuming time to move back thread mechanism。
Thread mechanism is moved back in rotation in this programme, it is arranged on the mould of injection machine, this mould includes fixed half and moving half, the right-hand member of cover half has half groove, the left end of dynamic model has half groove, dynamic model and cover half involutory after, between two and half grooves formed injection molding cavity, described cover half inner transverse runs through mounting groove, in this mounting groove, interference fit has fairlead, and this fairlead is internal has moving core for threaded engagement；Being provided with core gear on the cylindrical of described moving core, cover half is internally provided with and is perpendicular to mounting groove and moveable actively tooth bar, and this active tooth bar engages with core gear。
Beneficial effect: when after die sinking (dynamic model is away from cover half), actively the driving core gear of tooth bar rotates, so that whole moving core rotates, due to moving core and fairlead threaded engagement, and fairlead is interference fitted on cover half, and fairlead will not rotate along with moving core, so the change of team certainly of moving core makes it move in fairlead, thus moving core exits in injection molding cavity, omnidistance without artificial participation, what mechanical automation completed moving core moves back threaded process。It is higher that this utility model shortens the screw thread time of moving back of thread core, work efficiency。
Further, being provided through horizontal center push rod inside described moving core, the left end of this push rod is fixing with the push pedal outside mounting groove to be connected, and moving core completes to move back after screw thread works, and center push rod moves and ejects moulding。
Further, the length of described moving core is less than the length of mounting groove, it is simple to moving core moves in mounting groove。
Further, actively tooth bar is driven by straight-line feed motor so that actively tooth bar rotates。
Further, center push rod and moving core matched in clearance, do not affect the position of moving core when center push rod moves。
Accompanying drawing explanation
Fig. 1 is that this utility model embodiment rotates the structural representation moving back thread mechanism。
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: cover half 1, dynamic model 2, moving core 3, fairlead 4, core gear 5, actively tooth bar 6, center push rod 7, push pedal 8, injection molding cavity 9。
Embodiment rotates moves back thread mechanism substantially as shown in Figure 1: rotates and moves back thread mechanism, being arranged on injection machine, this injection machine includes cover half 1 and dynamic model 2, and the right-hand member of cover half 1 has half groove, the left end of dynamic model 2 has half groove, dynamic model 2 and cover half 1 involutory after, between two and half grooves formed injection molding cavity 9。
Cover half 1 is internal has the mounting groove extending transversely through cover half 1, and the right-hand member of this mounting groove communicates with injection molding cavity 9。Right part in this mounting groove is equipped with fairlead 4, the cylindrical of this fairlead 4 and mounting groove interference fit, and the endoporus of fairlead 4 is screwed hole。Moving core 3 is positioned at this mounting groove, and the length of moving core 3 is less than the length of mounting groove, and the right-hand member of moving core 3 is thread forming end, and this thread forming end can be inserted in injection molding cavity 9, for making the threaded portion of moulding。On moving core 3, the position near thread forming end has external screw thread, and the external screw thread of moving core 3 coordinates with fairlead 4 screwed hole, and moving core 3 is away from the left part spirogyrate forming core gear 5 in thread forming portion。
Cover half 1 has the rack bore communicated with mounting groove in the position being perpendicular to mounting groove, is sliding combined with actively tooth bar 6 in this rack bore, and this active tooth bar 6 engages with core gear 5, and actively tooth bar 6 is connected by shaft coupling is fixing with the outfan of straight-line feed motor。Center push rod 7 is coaxially located in mounting groove, and the right-hand member of this center push rod 7 runs through moving core 3(center push rod 7 and moving core 3 matched in clearance), the left end of center push rod 7 adopts bolt to fix to be connected with push pedal 8, and this push pedal 8 is connected with cylinder。
The work process of the present embodiment is: when after die sinking (dynamic model 2 is away from cover half 1), actively the driving core gear 5 of tooth bar 6 rotates, so that whole moving core 3 rotates, due to moving core 3 and fairlead 4 threaded engagement, and fairlead 4 is integrally fixed on cover half 1, moving core 3 rotates from injection molding cavity 9 and exits (thread forming portion exits moulding)；Now, push pedal 8 moves right, and center push rod 7 penetrates from moving core 3 and ejected from injection molding cavity 9 by moulding。
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this。Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented。The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim。
