For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of has the mould of plastics screw thread machine for quick operating structure improving transmission efficiency, the problem that solution moving platen move distance and thread core velocity of rotation have big difference.
For achieving the above object, the utility model provides following technical scheme: a kind of have the mould of plastics screw thread machine for quick operating structure improving transmission efficiency, comprise solid plate and moving platen, described moving platen is provided with thread core, described solid plate is provided with the pull bar that side is provided with tooth bar, described moving platen is provided with the driving member for driving thread core to rotate, described driving member comprises the first bevel gear and spur gear that are connected by a rotating shaft, described spur gear engages with pull bar, and described first bevel gear drives thread core to rotate by gear drive.
By adopting technique scheme, when moving platen moves away from solid plate, the spur gear arranged on the rack drives driving member on solid plate rotates, thus drive the first bevel gear to rotate, first bevel gear drives thread core to rotate, a kind of spur gear had on the mould of plastics screw thread machine for quick operating structure improving transmission efficiency of the utility model is identical with the gearratio of the first bevel gear, and gear-driven transmission efficiency is much larger than the transmission efficiency of worm screw, therefore perfection solves the problem that moving platen move distance and thread core velocity of rotation have big difference.
The utility model is set to further: described thread core is provided with relative to establishing threaded one end the second bevel gear engaged with the first bevel gear.
By adopting technique scheme, engage by the first bevel gear and the second bevel gear the transmission realized between driving member and thread core.
The utility model is set to further: described moving platen is provided with the jack inserted for pull bar.The utility model is set to further: described moving platen is provided with cavity volume, and described first bevel gear and the second bevel gear are positioned at cavity volume, and described jack is located at the side of cavity volume, and described axis of rotation is connected on the sidewall between cavity volume and jack.
By adopting technique scheme, slot being located at cavity volume side and conveniently driving member is set, not needing to increase the fixed structure being used for fixing driving member specially, structure is more simplified.
In sum, the utility model has and improves the mould of plastics screw thread machine for quick operating structure of transmission efficiency to have structure simple, the high and fireballing advantage of loosing core of transmission efficiency.

Detailed description of the invention
To the utility model, there is the mould of plastics screw thread machine for quick operating structure improving transmission efficiency referring to figs. 1 through Fig. 2 to be described further.
As shown in Figure 1, a kind of have the mould of plastics screw thread machine for quick operating structure improving transmission efficiency, comprises solid plate 1 and moving platen 2, wherein, solid plate 1 is provided with injection hole and pull bar 5, this injection hole does not on the way make marks, but injection hole is prior art for the art personnel.
In addition, moving platen 2 is provided with jack 9, cavity volume 8, die cavity 6 and thread core 3, thread core 3 establishes threaded one end to be arranged in die cavity 6, and the other end die wall run through between cavity volume 8 and die cavity 6 is positioned at cavity volume 8.
Moving platen 2 described in the present embodiment slides in the jack 9 of pull bar 5 on moving platen 2 and drives thread core 3 to rotate in moving process.Implementation is: jack 9 is located at the side of cavity volume 8, the side of pull bar 5 is provided with tooth bar, pull bar 5 is fixedly installed on solid plate 1, moving platen 2 is provided with the driving member for driving thread core 3 to rotate, one end of driving member coordinates with pull bar 5 upper rack, driving member comprises the first bevel gear 43 and spur gear 42 that are connected by a rotating shaft 41, and spur gear 42 engages with pull bar 5, and the first bevel gear 43 drives thread core 3 to rotate by gear drive.
In addition, rotating shaft 41 is rotatably connected on the sidewall between cavity volume 8 and jack 9, friction when reducing axis of rotation if necessary can arrange a bearing between this sidewall and rotating shaft, slot is located at cavity volume 8 side and conveniently driving member is set, do not need to increase the fixed structure being used for fixing driving member specially, structure is more simplified; Preferably, on sidewall, rotating shaft 41 installation position can arrange bearing for reducing friction.
Further, thread core 3 is provided with relative to establishing threaded one end the second bevel gear 31 engaged with the first bevel gear 43, engages by the first bevel gear 43 and the second bevel gear 31 transmission realized between driving member and thread core 3; First bevel gear 43 and the second bevel gear 31 are all arranged in cavity volume 8.
In addition, different according to Production requirement, thread core quantity freely can change with service condition, the present embodiment is chosen two thread cores 3 and is described further: according to said two thread cores 3 of said structure, one of them drives rotation by driving member, on this architecture basics, the thread core 3 that this is rotated by driving member drive arranges first spur gear 32, first spur gear 32 is located between the screw thread of thread core 3 and the first bevel gear 43 and the first spur gear 32 is positioned at cavity volume 8, another thread core 3 is provided with second spur gear 33 engaged with the first spur gear 32, owing to realizing transmission with a gears meshing, therefore the hand of spiral on two thread cores 3 needs anti-phase setting.
By adopting technique scheme, when moving platen 2 moves away from solid plate 1, the spur gear 42 arranged on the rack drives driving member on solid plate 1 rotates, thus drive the first bevel gear 43 to rotate, first bevel gear 43 drives thread core 3 to rotate, a kind of spur gear 42 had on the mould of plastics screw thread machine for quick operating structure improving transmission efficiency of the utility model is identical with the gearratio of the first bevel gear 43, and gear-driven transmission efficiency is much larger than the transmission efficiency of worm screw, therefore perfection solves the problem that moving platen 2 move distance and thread core 3 velocity of rotation have big difference.
More than make preferred embodiment of the present utility model, under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
