Abstract
A unscrewing mechanism used on a mould comprises a threaded core, a fixing block for the threaded core, a driving mechanism and a transmission system, wherein the fixing block for the threaded core isfastened on the mould; internal threads are formed on the fixing block; the upper end of the threaded core extends into the cavity of the mould; external threads meshing with the internal threads ofthe fixing block are formed on the threaded core; the input end of the transmission system is connected with the output shaft of the driving mechanism; the output end of the transmission system is connected with the threaded core; and a clutch is arranged between the transmission system and the output shaft of the driving mechanism. By utilizing the structure of the unscrewing mechanism, the threaded core in the unscrewing mechanism cannot conduct dieback in resetting.
Description
Technical field
The utility model relates to a kind of thread mechanism that takes off that is used on the mould, particularly is used in the thread mechanism that takes off in the mould of plastics.
Background technology
Now, mold manufacturing industry application aborning more and more widely, in daily life and work, we produce with mould employed and most of object that see, especially plastics and rubber, and, in order to reduce raw-material cost, many metal products before all replace with plastic product, and therefore, mould of plastics application aborning is more extensive.With the mould molding plastic product time, have internal thread and external screw thread in some product, for this series products, product can not be deviate from from mould with general stripping means, then need to take off thread mechanism and add that general stripping means could deviate from product from mould.At present, the mode of taking off screw thread mainly contains manually takes off screw thread, forces to take off screw thread and the motor-driven screw thread that takes off, manually taking off screw thread, generally to be used in small lot be in producing, when the material plasticity shape good, screw thread of product is more special, could use and force to take off screw thread, and in present production, adopt motor-driven the many of screw thread that take off.Now, a kind of motor-driven engage thread of taking off of utilizing motor and gear to take off screw thread is arranged, adopt this structure, because the motor rotation has inertia motion, so all numbers of the running of motor are inaccurate, make thread core running week number and Stroke Control difficult, add that to be used to power bigger, when thread core resets, be easy to dieback.Also having a kind of motor-driven engage thread of taking off is exactly to utilize gear and tooth bar to reach the purpose of taking off screw thread, and this structure needs to design mould very big, and action is unstable.
The utility model content
The purpose of this utility model is to be difficult for dieback when thread core resets in the thread mechanism in order a kind of thread mechanism that takes off that is used on the mould to be provided, to utilize structure of the present utility model to make to take off.
For achieving the above object, the thread mechanism that takes off that is used on the mould of the present utility model comprises thread core, thread core fixed block, driving mechanism and transmission system; Described thread core fixed block is fastened on the mould, and the thread core fixed block is provided with internal thread; The upper end of described thread core extend in the die cavity of mould, and thread core is provided with the external screw thread that is meshed with the internal thread of screw thread fixed block; The input of described transmission system is connected with the output shaft of driving mechanism, and the output of transmission system is connected with thread core; Be provided with clutch between the output shaft of described transmission system and driving mechanism.
This structure take off thread mechanism, when taking off screw thread, driving mechanism drives the thread core rotation by clutch and transmission system, because the thread core fixed block is fixed on the mould, is provided with internal thread on the thread core fixed block, simultaneously, on thread core, also be provided with the screw thread that is meshed with internal thread, therefore, thread core can deviate from product along moving on the axis direction of thread core from thread core; When needs reset thread core, driving mechanism makes the thread core counter-rotating by clutch and transmission system, after thread core rotates to needed position, the twisting resistance of thread core is greater than the clutch rated value, slipping of clutch makes and motor idle running can not continue to act on thread core, thus, can guarantee that thread core is not by dieback.
Specialize as of the present utility model, described transmission system comprises first rotating shaft, second rotating shaft, first gear, second gear, the 3rd gear and the 4th gear; One end of described first rotating shaft is connected with clutch, and the other end is located on the mould; Described first gear is located on first rotating shaft; Described second rotating shaft is located on the mould, and second gear and the 3rd gear are located on second rotating shaft, and described the 3rd gear is positioned at the top of second gear; Described the 4th gear is located on the thread core.
Specialize as of the present utility model, described driving mechanism is a motor.
Description of drawings
Fig. 1 is a three-dimensional view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated
As shown in Figure 1 be used for the thread mechanism that takes off on the mould, comprise thread core 1, thread core fixed block 2, driving mechanism, clutch 3 and transmission system 4.The upper end of described thread core 1 extend in the die cavity of mould, is convenient to the internal thread on the shaped article, is provided with screw thread on the pars intermedia of thread core 1; Described thread core fixed block 2 is fixed on the mould, one hole that is provided with internal thread is arranged in thread core fixed block 2, described thread core 1 passes the hole on the thread core fixed block 2, and the screw thread of thread core 1 pars intermedia is meshed with the internal thread of thread core fixed block 2; Described transmission system 4 comprises first rotating shaft 401, second rotating shaft 402, first gear 403, second gear 404, the 3rd gear 405 and the 4th gear 406.The upper end of described first rotating shaft 401 is located on the mould, the two ends of second rotating shaft 402 are located on the mould, described first gear 403 is installed on first rotating shaft 401, and second gear 404 and the 3rd gear 405 are installed on second rotating shaft 402, and the 4th gear 406 is installed on the thread core 1; Described driving mechanism is a motor 5, and motor 5 is installed on the mould, and described clutch 3 is installed between the output shaft and first rotating shaft 401 of motor 5.
The thread mechanism course of work of taking off of this structure is: when taking off screw thread, motor 5 is passed to first rotating shaft 401 by clutch 3 with motion, first rotating shaft 401 is passed to second rotating shaft 402 by first gear, 403 second gears 404 with motion, second rotating shaft 402 is passed to thread core 1 by the 3rd gear 405 and the 4th gear 406 with motion, thread core 1 moves downward under the threaded function of internal thread on the thread core fixed block 2 and thread core 1 pars intermedia, thread core 1 is deviate from from product, finished the process of taking off screw thread.When needs reset thread core, motor 5 reverses and by clutch 3 first rotating shaft 401 is passed in motion, first rotating shaft 401 is passed to second rotating shaft 402 by first gear, 403 second gears 404 with motion, second rotating shaft 402 is passed to thread core 1 by the 3rd gear 405 and the 4th gear 406 with motion, thread core 1 moves upward under the threaded function of internal thread on the thread core fixed block 2 and thread core 1 pars intermedia, when thread core 1 moves to needed position, the twisting resistance of thread core 1 is greater than clutch 2 rated values, slipping of clutch, make motor dally, can not continue to act on thread core, thus, can guarantee that thread core 1 is not by dieback.
