Description
Technical field
The utility model relates to die cast metal field, more specifically, relates to a kind of die casting thread and to loose core field.
Background technology
Along with die-cast part is large-scale in the industrial production must in application, for the technology how reducing procedure of processing and processing technology in production process, day by day become the problem of manufacturer's research, in the step that prior art is loosed core at die casting thread, two steps are generally divided into complete, the first step: manually to be accomplished fluently by screw thread hole by drill bit, second step: carry out tapping by screw tap, the female thread of final formation band, is completed by two steps, the 3rd step: product guarantor person examines entirely during the course.First huge manpower and material resources are expended, and cost is high, inefficiency, often can not meet the demand that industrial-scale uses, secondly, because manual operation can not the size of keyhole and tapping accurately, often cause processing not in place, batch wise differences is large, reprocess frequency high, What is more because the size of processing surpasses tolerance limit, directly causes product batch to be scrapped.
How to overcome prior art thread and loose core that cost is high, efficiency is low, the low inferior technical problem of yield rate perplexs row industry personnel always.
Utility model content
The utility model aims to provide that a kind of structure is simple, the die casting thread core-pulling device of high efficiency, low cost.
For this reason, the utility model provides a kind of die casting thread core-pulling device, comprise the first driver element, tooth bar, driven gear, thread mold insert and the second driver element, described first drive unit drives tooth bar moves back and forth, driven gear described in described rack drives comes and goes to rotate thus described thread mold insert is come and gone and rotates, and described second driver part drives described thread mold insert to carry out above-below direction back and forth movement, and the threaded portion of matching with die casting thread is established in described thread mold insert end.
Further, described first driver element comprises oil cylinder, and described oil cylinder output shaft is connected with described tooth bar.
Further, described tooth bar is Metal plate.
Further, described driven gear comprises and coaxially arranges female gear and sub-gear, described tooth bar and described sub-gears meshing, described sub-gear and described female gear coaxial rotation.
Further, the gear ratio of described female gear and described sub-gear is more than or equal to 3.
Further, described female gear engages with described thread mold insert.
Further, the upper and lower largest motion distance of described thread mold insert is L, and the thickness of described female gear is greater than L.
Further, described second driver part comprises oil cylinder, and described oil cylinder output shaft engages with thread mold insert and drives described thread mold insert to carry out above-below direction reciprocating motion.
Further, described driven gear, described thread mold insert are Metal plate.
Further, described first driver element comprises the oil cylinder of horizontally set, and described second driver element comprises the vertical oil cylinder that arranges or the first driver element comprises the vertical oil cylinder arranged, and described second driver element comprises the oil cylinder of horizontally set.
Further, tooth bar uniform motion described in described first drive unit drives.
The utility model has following technique effect: die casting thread core-pulling device structure of the present utility model is simple, to be loosed core step by the die casting thread that completes of integrated mode high efficiency, low cost, industrially has very strong generalization.
Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the overall schematic of the utility model die casting thread core-pulling device;
Fig. 2 is the local state figure of the utility model die casting thread core-pulling device;
Fig. 3 is the thread mold insert schematic diagram of the utility model die casting thread core-pulling device;
Fig. 4 is the die casting schematic diagram of the utility model die casting thread core-pulling device;
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Fig. 1-4 is overall schematic of the utility model die casting thread core-pulling device, comprise the first driver element 1, tooth bar 2, driven gear 3, thread mold insert 4 and the second driver element (not shown), described first driver element 1 drives tooth bar 2 to carry out reciprocal motion, preferably, described first driver element 1 is oil cylinder, the tooth bar 2 of described Metal plate drives described driven gear 3 to come and go and rotates thus make described thread mold insert 3 come and go rotation, and described thread mold insert end is provided with the threaded portion of matching with die casting thread.Threaded portion with treat die casting 5 need carry out the place that thread looses core and abut against, described second driver part drives described thread mold insert 4 to carry out above-below direction back and forth movement, when thread mold insert 4 in downward direction moves, described thread mold insert 4 carries out attacking thread 51 step simultaneously, finally complete and attack thread 51, when described second driver part drives described thread mold insert 4 to carry out upper direction, described thread mold insert 4 carries out de-thread 51 step simultaneously, finally completes de-thread 51.
Preferably, described driven gear 3 comprises and coaxially arranges female gear 32 and sub-gear 31, and described tooth bar 2 engages with described sub-gear 31, described sub-gear 31 and described female gear 31 coaxial rotation.Described female gear 32 is meshed with first turn of tooth 42 of described thread mold insert 4.Second turn of tooth 43 that described thread mold insert 4 is provided with first turn of tooth 42 and matches with the second driving mechanism, described female gear 32 is more than or equal to 3 with the gear ratio of described sub-gear 31, thus the moment of tooth bar 2 is effectively transmitted.Described thread mold insert about 4 largest motion distance is L, and the thickness of described female gear 32 is greater than L.Thus ensureing that thread mold insert 4 is when moving up and down, female gear 32 can not depart from thread mold insert 4.Described in best mode, driven gear, described thread mold insert are Metal plate.Described first driver element comprises the oil cylinder of horizontally set, and described second driver element comprises the vertical oil cylinder that arranges or the first driver element comprises the vertical oil cylinder arranged, and described second driver element comprises the oil cylinder of horizontally set.Preferably tooth bar uniform motion described in described first drive unit drives.
