Abstract
The invention discloses a slide mechanism of a bend pipe core drawing mold. The slide mechanism of the bend pipe core drawing mold comprises an oil cylinder, a slide block, a connecting block and a base; a circular arc surface matched with a bend pipe product is arranged above the base; a fixed point at one end of the slide block is rotatably fixed at one side above the base; the other end of the slide block rotates around the fixed point and along the circular arc surface, and the other end of the slide block is provided with a bar-shaped sliding chute; the oil cylinder is fixed on the other side above the base; a driving shaft of the oil cylinder is connected with one end of the connecting block, and the other end of the connecting block is provided with a positioning pin; and the positioning pin is arranged in the bar-shaped chute in an embedding and sliding mode. Compared with the traditional fan-shaped gear core drawing mold driven by a rack, the slide mechanism of the bend pipe core drawing mold, provided by the invention, has the advantages that the mold structure is single; the processing cost is lowered greatly; the mold opening cycle is short; the mold runs more reliably; the cycle of injecting and molding of the bend pipe product is shorter; and the later maintaining cost of the mold is low.
Description
Technical field
The present invention relates to mould manufacturing field, particularly a kind of bend pipe core-pulling die for the production of the bend pipe series products.
Background technology
Development along with die industry, technology is constantly reformed, traditional mould structure is produced the product of bend pipe class, substantially all be to realize by tooth bar and sector gear, the motion of rack drives sector gear, as in motion process, there is a place to block, all can causes the tooth above rack and pinion all to fracture, thereby cause the damage of mould, need often to change and maintenance, production efficiency is low and production cost is larger, also has other auxiliaries of this class mould a lot, causes the die cost can be very high, mechanism is just very complicated, and stability is just poorer.
Summary of the invention
In order to overcome defects, the invention provides a kind of mould knot of making and oversimplify, produces more reliable, the line position mechanism of the bend pipe core-pulling die of reduction die cost.
the present invention for the technical scheme that solves its technical problem and adopt is: a kind of line position mechanism of bend pipe core-pulling die, comprise oil cylinder, the line position piece, contiguous block and base, described base top is provided with the arc surface with bend pipe product coupling, described line position piece one end Fixed-point Motion of A is fixed on base top one side, the line position piece other end is around fixing a point and rotating along arc surface, and the other end of line position piece is provided with a bar shaped chute, described oil cylinder is fixed on base top opposite side, the driving shaft of oil cylinder connects an end of contiguous block, the other end of described contiguous block is provided with alignment pin, described alignment pin slides and is embedded in the bar shaped chute.
As a further improvement on the present invention, be provided with a fixed block outside described oil cylinder, fixed block is fixed on oil cylinder in mould.
The invention has the beneficial effects as follows: the present invention compares with traditional rack drives sector gear core-pulling die, has following having a few:
(1) the mould knot is oversimplified, very large minimizing processing cost, and opening period is short.
(2) the mould operation is more reliable, and injection moulding bend pipe Cycle of the products is shorter.
(3) maintenance cost in mould later stage is low.
Description of drawings
Fig. 1 is the matched moulds view of structure of the present invention;
Fig. 2 is the die opening state schematic diagram of structure of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, oil cylinder; 2, line position piece; 3, contiguous block; 4, base; 5, arc surface; 6, fixed point; 7, bar shaped chute; 8, alignment pin; 9, fixed block.
The specific embodiment
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Fig. 1 and Fig. 2 have shown a kind of embodiment of the line position mechanism of a kind of bend pipe core-pulling die of the present invention, comprise oil cylinder 1, line position piece 2, contiguous block 3 and base 4, described base 4 tops are provided with the arc surface 5 with bend pipe product coupling, described line position piece 2 one end Fixed-point Motion of As are fixed on base 4 top one sides, line position piece 2 other ends rotate around fixed point 6 and along arc surface 5, and the other end of line position piece 2 is provided with a bar shaped chute 7, described oil cylinder 1 is fixed on base 4 top opposite sides, the driving shaft of oil cylinder 1 connects an end of contiguous block 3, the other end of described contiguous block 3 is provided with alignment pin 8, described alignment pin 8 slides and is embedded in bar shaped chute 7, described oil cylinder 1 outside is provided with a fixed block 9, fixed block 9 is fixed on oil cylinder 1 in mould.When the mould matched moulds, the driving shaft of oil cylinder 1 promotes contiguous block 3 and moves, the alignment pin 8 of contiguous block 3 is in the interior slip of bar shaped chute 7 of line position piece 2 and drive line position piece 2 one ends and rotate along arc surface 5 during core rod with the bend pipe product inserts injection mold, after injection moulding is completed, oil cylinder 1 reopens, and the driving shaft of oil cylinder 1 retracts contiguous block 3, and drives line position piece 2 along arc surface 5 backward rotation, line position piece 2 is extracted the core rod of bend pipe product from product, so cycling.
