Description
Technical field
The present invention relates to a kind of crosslinking cable production line quick die change device.
Background technology
Wires and cables industry generally uses CCV three-layer co-extruded production line when producing the insulated wire cores of midium voltage cable.The feature of this production line is that length is longer, generally more than 120 meters, the longlyest can reach more than 200 meter.Because extruding of cable is that one end at production line completes; then need to carry out being cross-linked through piping, the process such as cooling; need to waste a lot of materials so this kind of production line is started shooting at every turn; and the feature that cable is produced just determines when changing product specification and needs to shut down more mold exchange, therefore how to reduce the material consumption of start, the machine stop times how reduced when changing specification becomes the key factor of limit product cost.
Summary of the invention
The object of the invention is for above-mentioned existing problems, provide a kind of easy to use, die change quick, the non-stop-machine crosslinking cable production line quick die change device of Stability Analysis of Structures, die change.
The object of the present invention is achieved like this: comprise big mould core, small mould core and stay pipe, small mould core and stay pipe are threaded connection, the circular cone table top that small mould core has filling tube and mates with the inner chamber of big mould core, the left half module that small mould core is split by radial direction and the docking of right half module combine and on a left side, the joint of right half module arranges a formation left side, concavo-convex position at least one group of coupling, the docking of right half module fastens location structure, the left semicanal that stay pipe is split by radial direction, the docking of right semicanal combines and on a left side, the joint of right semicanal arranges a jog formation left side at least one group of coupling, the docking of right semicanal fastens location structure, stay pipe is fastened on a left side for stay pipe by elastic buckles, form left in the draw-in groove of right semicanal, the docking fastening structure of right semicanal.
The present invention, the filling tube of small mould core and the connection of big mould core are tight fit connection structure.
The present invention, the length of filling tube is greater than 10mm, and small mould core is after insertion big mould core, and the front end face of filling tube and the front end face of big mould core are at same plane.
The present invention, the wall thickness of filling tube is 0.6 ~ 0.8mm, and the front end wall thickness of big mould core is 0.6 ~ 0.8mm.
The present invention, has following good effect: small mould core adopts radial mode of splitting to make small mould core can install easily and unload under quantity-produced prerequisite, and can Reusability; Stay pipe also can be installed easily and unload, and stay pipe can ensure that the shape of small mould core is accurate, stable, facilitates small mould core to insert big mould core, makes small mould core assembly and disassembly convenient.
The present invention, has that easy to use, die change is quick, the non-stop-machine advantage of Stability Analysis of Structures, die change.
The present invention is further illustrated by reference to the accompanying drawings for embodiment below.

In figure, 1, big mould core; 2, filling tube; 3, the inner chamber of big mould core; 4, circular cone table top; 5, left half module; 6, right half module; 7, left semicanal; 8, right semicanal; 9, concavo-convex position; 10, jog; 11, elastic buckles; 12, draw-in groove.
Embodiment
Referring to figs. 1 through Fig. 3, the present embodiment is a kind of crosslinking cable production line quick die change device, comprise big mould core 1, small mould core and stay pipe, small mould core and stay pipe are threaded connection, the circular cone table top 4 that small mould core has filling tube 2 and mates with the inner chamber 3 of big mould core, the left half module 5 that small mould core is split by radial direction and right half module 6 docking combine and on a left side, the joint of right half module arranges at least one group of concavo-convex position 9 of mating and forms a left side, the docking of right half module fastens location structure, the left semicanal 7 that stay pipe is split by radial direction, the docking of right semicanal 8 combines and on a left side, the joint of right semicanal arranges at least one group of jog 10 mated and forms a left side, the docking of right semicanal fastens location structure, stay pipe is fastened on a left side for stay pipe by elastic buckles 11, form left in the draw-in groove 12 of right semicanal, the docking fastening structure of right semicanal, wherein, in the draw-in groove 12 of elastic buckles 11 in one end of the close small mould core be threaded of stay pipe at stay pipe, fastening plays fastening effect to small mould core, several elastic buckles fastenings can be set according to the length of stay pipe, to ensure the stability of stay pipe, elastic buckles 11 adopts expanding ring, the filling tube of small mould core and the connection of big mould core are tight fit connection structure, the length of filling tube is greater than 10mm, and small mould core is after insertion big mould core, and the front end face of filling tube and the front end face of big mould core are at same plane, the wall thickness of filling tube is 0.6 ~ 0.8mm, and the front end wall thickness of big mould core is 0.6 ~ 0.8mm.
The present invention, the wall thickness of filling tube should at 0.6 ~ 0.8mm, and the front end wall thickness of the big mould core be mated also should at 0.6 ~ 0.8mm.So both having ensure that can not be excessive and cause the eddy current of sizing material because of the die nose wall thickness after combination, and then causes the crosslinked in advance easy damage that also can not make mould of sizing material.The length of filling tube should be greater than 10mm, ensure that small mould core coordinates rear stability with big mould core, and to ensure that it to insert after big mould core the front end face of filling tube and the front end face of big mould core in same plane, this ensure that can not be contained in big mould core because of the small mould core front end after combination inner and cause the eddy current of sizing material, and then cause being cross-linked in advance of sizing material, it also avoid small mould core front end and give prominence to and reduce sizing material and cause product quality to decline to the pressure of conductor.Gap after the external diameter of filling tube coordinates with big mould core should be less than 0.1mm, ensures that two core rods closely cooperate, does not have material and caused sizing material to be detained by getting into fit clearance, and then cause being cross-linked in advance of these sizing materials.
Use of the present invention, when large gauge conductor will change small dimension conductor, after the blank area of conductor enters cross-head, small mould core and stay pipe combined and conductor is coated on centre, then small mould core being inserted big mould core, finally adjusting extruder and extruding layer is met the requirements.If small dimension conductor changes large gauge conductor, before the blank area of conductor enters cross-head, device is unloaded, remove from conductor.
Quality of fit of the present invention is high, rational in infrastructure, can meet the concentricity requirement extruded.
