Description
Technical field:
The utility model relates to a kind of extruding machine, is specifically a kind of head air extraction device of extruding machine.
Background technology:
The heart yearn of cable is when plastic extruding insulated sheath, if be full of more air in the head of extruding machine, the bonding tightness of sheath and metal core can be affected when the sheath of the incoming line parcel extrusion molding of metal core ingress engine head, like this, in follow-up use procedure, easily cause the stripping of sheath and metal core, impact uses.
Utility model content:
Technical problem to be solved in the utility model is, there is provided a kind of head air extraction device that can improve the extruding machine of core and sheath bonding tightness, this device makes can better be combined with core when extrusion molding sheath by the air extracted in the head of extruding machine.
Technical solution of the present utility model is, a kind of head air extraction device of extruding machine is provided, comprise extruding machine, extruding machine is provided with head, head one end is provided with incoming line, also comprise a plunger rod and vavuum pump, the diameter of plunger rod is greater than head incoming line, one end of plunger rod is provided with the insertion end can inserting incoming line, plunger rod and insertion end are coaxially arranged, plunger rod and insertion end axial direction are also provided with the threading via hole that can pass for core, the circumferential wall of plunger rod is also provided with tracheae through hole, tracheae through hole and threading via hole through, the tracheae of vavuum pump penetrates tracheae through hole, also fixed support is provided with below plunger rod, fixed support and extruding machine are fixed, fixed support is provided with sliding bar, plunger rod can be slided on sliding bar.
To adopt after above structure compared with prior art, the utility model has the following advantages: insertion end inserted in incoming line, then plunger rod abuts head, by penetrating the tracheae extracting air of tracheae through hole, the space making the extrusion molding in head form sheath keeps vacuum, can improve the tightness degree of core and sheath.
As preferably, described plunger rod is fixed with connecting rod, and connecting rod is provided with sliding sleeve, and sliding sleeve is set on sliding bar.
Accompanying drawing illustrates:
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of head air extraction device of extruding machine, comprise extruding machine 1, extruding machine 1 is provided with head 2, head 2 one end is provided with incoming line 5, also comprise a plunger rod 3 and vavuum pump 4, the diameter of plunger rod 3 is greater than the incoming line 5 of head 2, one end of plunger rod 3 is provided with the insertion end 6 can inserting incoming line 5, plunger rod 3 and insertion end 6 are coaxially arranged, plunger rod 3 and insertion end 6 axial direction are also provided with the threading via hole that can pass for core, plunger rod 3 pipe through-hole, fixed support 7 is also provided with below plunger rod 3, fixed support 7 is fixed with extruding machine 1, fixed support 7 is provided with sliding bar 8, plunger rod 3 is fixed with connecting rod 9, connecting rod 9 is provided with sliding sleeve 10, sliding sleeve 10 is set on sliding bar 8 and slides.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion, include within scope of patent protection of the present utility model.
