Abstract
The present invention relates to a kind of mould bend pipe rotating core-pulling mechanism, it includes sliding block, take-up housing, bend pipe core rod, fixed block, the first pull bar, guide pad, oil cylinder, limited block, rotating shaft, back-moving spring and connection mold insert.Connected between first pull bar and oil cylinder by connecting rod, first pull bar again with the sliding block by locking member in succession, the bend pipe core rod and spill spin block by locking member in succession and between take-up housing by rotating shaft in succession, the present invention is in mould core pulling, coordinated by more complicated mechanical structure, bend pipe core rod automatic rotary is turned the demoulding, realize the automated production of complicated product, improve production efficiency.
Description
Technical field
Field, more particularly to a kind of mould bend pipe rotating core-pulling mechanism are manufactured the present invention relates to injection forming mold.
Background technology
At present, there is bending core pulling for product, use general core-pulling mechanism mould structure can be made very complicated, required sky
Between it is huge, thus general core-pulling mechanism can not realize；Or die size can be brought to increase, the board model of matching also accordingly increases
Greatly, cause injection molding cycle long, cause product cost to rise, profit declines.
Thus, it is necessary to propose new technical scheme to solve above-mentioned technical problem.
The content of the invention
Object of the present invention is to provide a kind of mould bend pipe rotating core-pulling mechanism occupied little space.
To realize object defined above, the present invention is adopted the following technical scheme that：A kind of mould bend pipe rotating core-pulling mechanism, it includes
It is oil cylinder, fixed block, sliding block, take-up housing, bend pipe core rod, the first pull bar, the first limited block, spill spin block, the second pull bar, rotating shaft, multiple
Position spring, the second limited block, connection mold insert, the 3rd pull bar, the three, the 4th and the 5th limited block, the bend pipe core rod are installed on
In spill spin block, spill spin block is installed in take-up housing by rotating shaft, and the first pull bar is installed on the bottom side of sliding block, and connection mold insert is installed on
In first pull bar, oil cylinder is arranged on the left side of fixed block, and the first limited block is installed in take-up housing, the first pull bar, back-moving spring,
3rd pull bar, the 4th limited block, the 5th limited block are installed in take-up housing, and second, third limited block is fixed on take-up housing bottom,
The bend pipe core rod and spill spin block by locking member in succession and between take-up housing by rotating shaft in succession, the mould bend pipe rotation
Core-pulling mechanism can promote bend pipe core rod automatic rotating stripping demoulding during injection molded.
Inventive die bend pipe rotating core-pulling mechanism occupies little space, so that the board of matching is small, reduction equipment and energy consumption
Cost, the quality of lifting production product, improves production efficiency, increases product profit.

Embodiment
Refer to shown in Fig. 1 to Fig. 5, inventive die bend pipe rotating core-pulling mechanism 10 includes oil cylinder 11, fixed block 12, slided
Block 13, take-up housing 14, bend pipe core rod 15, the first pull bar 16, the first limited block 17, spill spin block 18, the second pull bar 19, rotating shaft 20,
Back-moving spring 21, the second limited block 22, connection mold insert 23, the 3rd pull bar 24, the 3rd limited block 25, the 4th limited block 26 and the 5th
Limited block 27, the bend pipe core rod 15 is installed in spill spin block 18, and spill spin block 18 is installed in take-up housing 14 by rotating shaft 20, the
One pull bar 16 is installed on the bottom side of sliding block 13, and connection mold insert 23 is installed in the first pull bar 16, and oil cylinder 11 is arranged on fixed block 12
Left side, the first limited block 17 is installed in take-up housing 14, and the first pull bar 16, the pull bar the 24, the 4th of back-moving spring 21 the 3rd are spacing
Block 26, the 5th limited block 27 are installed in take-up housing 14, and the second limited block 22, the 3rd limited block 25 are fixed on the bottom of take-up housing 14
Portion.
In injection production process, after the completion of injection, the rotary core pulling time-division of inventive die bend pipe rotating core-pulling mechanism 10
Into three steps, first, oil cylinder 11 pulls the first pull bar 16, and connection mold insert 23 and sliding block 13 are moved rearwardly into a pre-determined bit simultaneously
Put；Secondly, oil cylinder 11 pulls the first pull bar 16, connection mold insert 23 and sliding block 13 to continue to be moved rearwardly into another precalculated position, together
When connection mold insert 23 tangle the second pull bar 19, drive the second pull bar 19 to be moved rearwards by simultaneously, now spill spin block 18 is in the second pull bar
20 rotated around the shaft together with bend pipe core rod 13 under 19 drive；Finally, oil cylinder 11 continues to be moved rearwardly into a final position,
Under sliding block 13 is acted on, the 4th limited block 26 and the 5th limited block 27 move down required distance, while take-up housing 14 starts
Move backward together, complete whole core pulling action.
Inventive die bend pipe rotating core-pulling mechanism 10 occupies little space, so that the board of matching is small, reduction equipment and energy
Cost is consumed, the quality of lifting production product improves production efficiency, increases product profit.
Although for example purpose, having been disclosed for the preferred embodiment of the present invention, the ordinary skill people of this area
Member will realize in the case of scope and spirit of the present invention disclosed in not departing from by appended claims, various to change
It is possible for entering, increasing and replacing.
