Abstract
The invention relates to a rotary core-pulling mechanism for a die elbow. The rotary core-pulling mechanism comprises a slide block, a slide block seat, an elbow, a mold core, a fixed block, a pull bar, a guide block, an oil cylinder, a stop block, a rotating shaft, a reset spring and a connection mold insert, wherein the pull bar is connected with the oil cylinder through a connecting rod and connected with the slide block through a retaining member, and the elbow mold core is connected with a rotary block through a retaining member and connected with the slide block seat through the rotating shaft. According to the invention, during die core pulling, automatic rotation and demoulding of the elbow mold core are realized through complex cooperation of mechanical structures, automatic production of complex products is realized, and production efficiency is improved.
Description
Technical field
The present invention relates to injection forming mold and manufacture field, particularly a kind of mould bend pipe rotating core-pulling mechanism.
Background technology
At present, have bending to loose core for product, the general core-pulling mechanism that adopts can make mould structure very complicated, and required space is huge, thereby general core-pulling mechanism can not be realized; Or can bring die size to increase, the also corresponding increase of the board model of coupling, causes injection molding cycle long, cause product cost to rise, profit declines.
So, be necessary to propose new technical scheme to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide a kind of mould bend pipe rotating core-pulling mechanism that takes up room little.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of mould bend pipe rotating core-pulling mechanism, it comprises oil cylinder, fixed block, slide block, take-up housing, bend pipe core rod, pull bar, the first limited block, spill spin block, pull bar, rotating shaft, back-moving spring, the second limited block, connect mold insert, pull bar, the 3rd, the the 4th and the 5th limited block, described bend pipe core rod is installed in spill spin block, spill spin block is installed in take-up housing by rotating shaft, pull bar is installed on the bottom side of slide block, connecting mold insert is installed in pull bar, oil cylinder is arranged on the left side of fixed block, the first limited block is installed in take-up housing, pull bar, back-moving spring, pull bar, the 4th limited block, the 5th limited block is installed in take-up housing, second, the 3rd limited block is fixed on take-up housing bottom, described bend pipe core rod and spill spin block by locking member in succession and and take-up housing between by rotating shaft in succession, described mould bend pipe rotating core-pulling mechanism can impel the automatic rotation demoulding in injection molded process of bend pipe core rod.
Mould bend pipe rotating core-pulling mechanism of the present invention takes up room little, thereby the board of coupling is little, and reduction equipment and energy consumption cost promote the quality of producing product, enhance productivity, and increase product profit.

The specific embodiment
Refer to shown in Fig. 1 to Fig. 5, mould bend pipe rotating core-pulling mechanism 10 of the present invention comprises oil cylinder 11, fixed block 12, slide block 13, take-up housing 14, bend pipe core rod 13, pull bar 16, the first limited block 17, spill spin block 18, pull bar 19, rotating shaft 20, back-moving spring 21, the second limited block 22, connect mold insert 23, pull bar 24, the 3rd limited block 25, the 4th limited block 26 and the 5th limited block 27, described bend pipe core rod 13 is installed in spill spin block 18, spill spin block 18 is installed in take-up housing 14 by rotating shaft 20, pull bar 16 is installed on the bottom side of slide block 13, connecting mold insert 23 is installed in pull bar 16, oil cylinder 11 is arranged on the left side of fixed block 12, the first limited block 17 is installed in take-up housing 14, pull bar 16, back-moving spring 21, pull bar 16, the 4th limited block 26, the 5th limited block 27 is installed in take-up housing 14, the second limited block 22, the 3rd limited block 25 is fixed on take-up housing 14 bottoms.
In injection moulding production process, after injection moulding completes, when mould bend pipe rotating core-pulling mechanism of the present invention 10 rotary core pulling, be divided into three steps, first, oil cylinder 11 pulls pull bar 16, and connection mold insert 23 and slide block 13 move to a precalculated position simultaneously backward; Secondly, oil cylinder 11 pulls pull bar 16, connection mold insert 23 and slide block 13 to continue to move to backward another precalculated position, connect mold insert 26 simultaneously and tangle pull bar 16, drive pull bar 16 to move backward, now spill spin block 18 20 rotates around the shaft under the drive of pull bar 16 together with bend pipe core rod 13 simultaneously; Finally, oil cylinder 11 continues to move to backward a final position, and under slide block 13 effects, the 4th limited block 26 and the 5th limited block 27 move down required distance, and take-up housing 14 starts to move backward together simultaneously, completes the whole action of loosing core.
Mould bend pipe rotating core-pulling mechanism 10 of the present invention takes up room little, thereby the board of coupling is little, and reduction equipment and energy consumption cost promote the quality of producing product, enhance productivity, and increase product profit.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
