Description
Technical field
The utility model relates to the technical field of core-pulling mechanism, especially a kind of linkage rod slide block mechanism realizing rotary core pulling.
Background technology
In injection mo(u)lding, when shape in product is with bend pipe structure, because the core of bend pipe is arcuate structure, and core pulling distance is large, when designing except need adopting two cores and separately loosing core, also needs to adopt rotation mode to loose core.This just needs simple for injection mold linear pattern die open/close movement to be changed into arc curve motion, adds trouble to plastics injection mould structural design.
At present, conventional rotating core-pulling mechanism is generally slide block tooth bar core-pulling mechanism, but it is mainly applicable to the large occasion of interiors of products structure space, and production cost is higher.The present invention adopts a kind of connecting rod slider core-pulling mechanism, and being applied to variously needs rotary core pulling occasion.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of linkage rod slide block mechanism realizing rotary core pulling, and being applicable to variously needs rotary core pulling occasion.
The utility model solves the technical scheme that its technical problem adopts: a kind of linkage rod slide block mechanism realizing rotary core pulling, has the hydraulic cylinder be arranged in outside injection mold, is placed in the slide block of hydraulic cylinder and is placed in the arcuate movement slide guide assembly of injection mold; Described arcuate movement slide guide assembly comprise outer guide runner, interior guide runner, do between the two along outer guide runner and interior guide runner arcuate movement long core, be hinged on the first connecting rod of long core afterbody and be fixed on the short core of long core head; The described pin joint being hinged on the first connecting rod of long core head is also hinged with second connecting rod, and the other end of described second connecting rod and the head of slide block are hinged.
Further restriction, the center of circle of the outer guide runner described in technique scheme, the center of circle of interior guide runner and the center of circle of long core coincide, and the other end of described first connecting rod is hinged on the circle centre position that three coincides.
Further restriction, the linkage rod slide block mechanism described in technique scheme also has the angled-lift splits seat being placed in injection mold and completing side core-pulling motion for controlling short core.
Further restriction, the second connecting rod described in technique scheme and outer guide runner and interior guide runner are staggered and distribute.
The beneficial effects of the utility model are: this kind of linkage rod slide block mechanism realizing rotary core pulling, reasonable in design, overall volume is less, and being applicable to variously needs rotary core pulling occasion, not easily there is interference in rotary core pulling process, ensure that the quality of product.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
See Fig. 1 and Fig. 2, a kind of linkage rod slide block mechanism realizing rotary core pulling, in injection molding process, complete rotary core pulling action, there is the hydraulic cylinder 1 be arranged in outside injection mold, be placed in the slide block 2 of hydraulic cylinder 1 and be placed in the arcuate movement slide guide assembly of injection mold.
See Fig. 1, Fig. 2 and Fig. 3, arcuate movement slide guide assembly comprise outer guide runner 3, interior guide runner 4, do between the two along outer guide runner 3 and interior guide runner 4 arcuate movement long core 5, be hinged on the first connecting rod 6 of long core 5 afterbody and be fixed on the short core 7 of long core 5 head, see Fig. 4 and Fig. 5.Wherein, the core pulling distance of long core 5 was controlled by hydraulic system with the time of loosing core.
See Fig. 1 and Fig. 2, the pin joint being hinged on the first connecting rod 6 of long core 5 head is also hinged with second connecting rod 8, and the other end of second connecting rod 8 and the head of slide block 2 are hinged.
See Fig. 2 and Fig. 3, the center of circle of the center of circle of outer guide runner 3, the center of circle of interior guide runner 4 and long core 5 coincides, and the other end of first connecting rod 6 is hinged on the circle centre position that three coincides.
See Fig. 1 and Fig. 2, linkage rod slide block mechanism also has the angled-lift splits seat 9 being placed in injection mold and completing side core-pulling motion for controlling short core 7.
See Fig. 1, second connecting rod 8 is staggered with outer guide runner 3 and interior guide runner 4 and distributes, and at grade, second connecting rod 8, in another one plane, effectively avoids second connecting rod 8 to produce interference in motion process for outer guide runner 3 and interior guide runner 4.
The operation principle of this linkage rod slide block mechanism is as follows:
After mold injection, slide block 2 in hydraulic cylinder 1 drives second connecting rod 8 outwards to move, first connecting rod 6 and long core 5 are under the drive of second connecting rod 8, arcuate movement is done between the two along outer guide runner 3 and interior guide runner 4, the arcuate movement of first connecting rod 6 and long core 5 is changed into the rectilinear motion of slide block 2, thus complete the rotary core pulling motion of long core 5; Simultaneously, short core 7 outwards moves under the effect of angled-lift splits seat 9 in mould die sinking, thus completes the side core-pulling motion of short core 7, so far completes the motion of loosing core of whole secondary mould.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
