Abstract
Mould of plastics tooth bar Angle Pin gear automatic threads demoulding device, comprise top clamping plate, top clamping plate is installed core and tooth bar Angle Pin, and all fix by core fixing plate, plastic side direction screwed hole is shaping by thread core, thread core is connected with gear shaft by bolt, gear shaft right-hand member with thread core pitch, the external screw thread that rotation direction is all consistent, this external screw thread and sleeve nut screw, sleeve nut is fixed on die cavity by holding screw circumference, during die sinking, the translate linear motion of dynamic model part is become the rotary motion of gear shaft by described tooth bar Angle Pin, thread core is driven to rotate and move axially along sleeve nut by gear shaft, realize automatic threads demoulding.This programme, by adopting tooth bar Angle Pin gear engagement mechanism, can ensure that gear drive tooth contact area, compression are constant, reduces gear teeth fatigue strength, improves Leave out thread device longevity and mold work reliability.
Description
Technical field
The utility model relates to mould of plastics automatic threads demoulding, particularly relates to mould of plastics tooth bar Angle Pin, gears meshing realizes automatic threads demoulding device.
Background technology
When plastic has helicitic texture, often use rack pinion automatic threads demoulding mechanism.Rack and pinion is the major part of this mechanism, and rack and pinion engages each other, and be the rotary motion of thread core by the translate linear motion of die sinking, this mechanism should ensure automatically deviating from of thread core, ensures that self work is smooth and easy, reliable again.Existing rack pinion Leave out thread mechanism, because thread core, gear are while rotation, also to axially move, make any time tooth bar, the contact area of the gears meshing gear teeth all changes, cause stress suffered by the gear teeth to there is fluctuation, load diatibution is uneven, easily make the gear teeth produce contact fatigue or local stress excessive and produce spot corrosion, the failure mode such as local fatigue fractures, affect mold work reliability.
Summary of the invention
The purpose of this utility model is the shortcoming existed to overcome prior art, a kind of application tooth bar Angle Pin and gears meshing are provided, while guarantee realizes that the rectilinear motion of folding mould is converted to the rotary motion of thread core, can also ensure that suffered by the tooth bearing sum that any time engages, stress is constant, the uniform automatic threads demoulding device of gear teeth load diatibution.
The technical scheme of the utility model mould of plastics tooth bar Angle Pin gear automatic threads demoulding device is: comprise top clamping plate, top clamping plate is installed core and tooth bar Angle Pin, and all fix by core fixing plate, plastic side direction screwed hole is shaping by thread core, thread core is connected with gear shaft by bolt, gear shaft right-hand member with thread core pitch, the external screw thread that rotation direction is all consistent, and screw with sleeve nut, sleeve nut is fixed on die cavity by holding screw circumference, when it is characterized in that die sinking, described tooth bar Angle Pin drives thread core rotate and move axially along sleeve nut by gear shaft, thread core is made to depart from plastic, reach automatic threads demoulding object.
The utility model discloses a kind of mould of plastics tooth bar Angle Pin gear automatic threads demoulding device, by adopting gear engagement mechanism, when utilizing die sinking, the translate linear motion of injector dynamic model part becomes the rotary motion of gear shaft, drive thread core rotate and move axially, and then realize automatic threads demoulding.Application tooth bar Angle Pin can ensure that gear drive tooth contact area, compression are constant, reduces gear teeth fatigue strength, improves Leave out thread device longevity and mold work reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mould of plastics tooth bar Angle Pin gear automatic threads demoulding device;
Fig. 2 is the fragmentary section views of Fig. 1.
Detailed description of the invention
The utility model relates to a kind of mould of plastics tooth bar Angle Pin gear automatic threads demoulding device, as shown in Fig. 1 ~ 2, comprise top clamping plate (1), top clamping plate (1) is installed core (2) and tooth bar Angle Pin (3), and all fix by core fixing plate (4), plastic (5) side direction screwed hole is shaping by thread core (6), thread core (6) is connected with gear shaft (8) by bolt (7), gear shaft (8) right-hand member with thread core (6) pitch, the external screw thread that rotation direction is all consistent, this external screw thread and sleeve nut (9) screw, sleeve nut (9) is fixed on die cavity (11) by holding screw (10) circumference, when it is characterized in that die sinking, the translate linear motion of dynamic model part is become the rotary motion of gear shaft (8) by described tooth bar Angle Pin (3), thread core (6) is driven to rotate and move axially along sleeve nut (9) by gear shaft (8), realize automatic threads demoulding.Application tooth bar Angle Pin (3) can ensure that gear drive tooth contact area, compression are constant, reduces gear teeth fatigue strength, improves Leave out thread device longevity and mold work reliability.
