Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
A kind of compound core pipe core pulling molding device as shown in Figure 1, 2, 3, including limit assembly, core pulling component, limit assembly packet
The limited block 1 of laterally longer rectangular shape is included, the limit hole 11 for set metal pipe, limit are machined in limited block 1
The internal diameter in position hole 11 is equal to the outer diameter of metal tube, to form the clamping lucky to metal tube.Core pulling component includes and limit hole
The mandrel 2 of 11 axis overlapping, the spindle component positioned at 11 front side of limit hole, mandrel 2, which includes that steel is integrally formed, to be sequentially connected
Linkage section 21 and profiled section 22, spindle component includes shifter and connector, and shifter can be straight along 11 axis direction of limit hole
Line movement, connector are fixed in shifter, and 21 releasable connection of linkage section is in connector, so that mandrel 2 is in spindle component
Effect is lower to have with limit hole 11 linear motion concentric and along its axis direction.
In the present embodiment, profiled section 22 is cylinder, and the length of profiled section 22 is greater than the metal pipe range being set in limit hole 11
Degree.22 end of profiled section, which is connected through a screw thread releasable connection, internal module 23.
In the present embodiment, internal module 23 is in aciculiform or by the gradually big truncated cone-shaped backward of profiled section 22.
In forming process, it is clamped firstly, metal pipe sleeve is fitted into be formed in limit hole 11；Then it is squeezed out by double helix
Machine from open-ended PP, PE that melting is injected into metal tube of metal tube or other may be molded to the raw material of interior plastic tube to filling
Inside full metal tube；Hereafter, the plastic raw materials semi-solid preparation of molten condition is waited, mandrel 2 is inserted into metal tube by starting shifter,
At this point, 2 end of mandrel internal module 23 select aciculiform, by be transitioned by the tip of aciculiform profiled section 22 cylinder it is gradually big
Insertion squeezes out the corresponding plastic raw materials of mandrel 2 until profiled section 22 is stretched out from the other end, i.e., mandrel 2 occupies original positioned at gold
The position for belonging to tube hub, remaining plastic raw materials become interior plastic tube after the cooling period between mandrel 2 and metal tube.Additional,
After being inserted into for the first time, the internal module 23 of stretching is changed to truncated cone-shaped, shifter work, which is retracted, extracts mandrel 2 out, passes through rotary table
Gradually big diameter remove plastic raw materials again, to obtain relatively thin interior plastics tube thickness, have the advantages that plastic tube
It can have biggish internal diameter simultaneously and reduce the weight of multiple tube.The plastic raw materials for being extruded removal can recycle again,
Waste is not will cause.The through-hole of mandrel 2 and limit hole 11 is that the plastics bore that ensure that mandrel 2 generates with metal tube is also same
Axis, so that the interior plastic tube that core pulling is formed is with each to more uniform thickness and the higher geometric tolerance of precision.
In the present embodiment, linkage section 21 includes columned standard shaft 211 and the limiting slot being recessed inwardly by 211 side of standard shaft
212.Connector includes fixed block 41 and the link block 42 for being articulated with fixed block 41, and there are two the tools of link block 42 and passes through quadrangle
Hinge is hinged on fixed block 41, and the counter surface of two link blocks 42 has limit ridge 43 corresponding with limiting slot 212.Four
Side shape hinge can realize the folding of link block 42, the limit ridge on link block 42 by way of pulling or motor/cylinder stretches
43 form clamping with limiting slot 212 just in closure, to realize the releasable connection of mandrel 2 and connector.In the present embodiment
Limiting slot 212 have it is multiple, so as to by clamping position adjustings change mandrel 2 it is long from the outside extension of connector
Degree, to adapt to needed for the multiple tube core pulling of different length.
In the present embodiment, shifter includes guide rail 31 and the mobile station 32 for being movably connected to guide rail 31, fixed block 41 are affixed
In 32 top surface of mobile station.Guide rail 31 can be fixed on same bracket to produce with limited block 1.Mobile station in the present embodiment
32 pass through the relative motion of chain drive realization and guide rail 31.
In the present embodiment, 11 both ends of limit hole have the baffle 12 being mounted on limited block 1 by screw releasable connection.Baffle
12 surfaces have the through-hole 13 of corresponding limit hole 11, and 13 diameter of through-hole is less than limit hole 11.It can be realized by baffle 12 to metal
The further limit of pipe prevents the interaction force of plastic raw materials and mandrel 2 during core pulling from causing metal tube mobile, simultaneously
What through-hole made that mandrel 2 still can be convenient, which pass through, carries out core pulling work.
In the present embodiment, pass through the machining runner 14 for having a plurality of perforation, 14 distributing position position of runner in limited block 1
In the side of limit hole 11, runner 14 is connected with the circulating pump with heat exchanger, by circulating pump in runner 14 circulating hot water
Or cold water, it can be achieved that limited block preheating or cooling, the preflood preheating of plastic raw materials can prevent melting raw material contact temperature
Premature cure agglomeration occurs when spending lower limited block, to improve Forming Quality；It can be mentioned after the completion of core pulling by cooling
The curing molding speed of plastic tube in height improves production efficiency.Heat exchanger provides the effect of heating or refrigeration for moisture in circulating pump
Fruit.
Only preferred embodiments of the present invention will be described for above embodiments, not to the spirit and scope of the present invention
It is defined, without departing from the design concept of the invention, ordinary people in the field makes technical solution of the present invention
