Description
Technical field:
The utility model relates to a kind of extruded mould that is installed on the extruder head, relates in particular to wrap up the extruded mould of the plastic extruding machine that the outside insulating barrier of electric wire uses, and specifically is a kind of extrusion die that is used for the double-deck lining of electric wire.
Background technology:
People with electric general knowledge is very clear; The outside insulating barrier of electric wire generally all is with the plastic overmold of the tool insulation property outside at electric wire with plastic extruding machine; Industry personnel get used to plastic extruding machine the production technology of plastic overmold in the outside of electric wire of tool insulation property being called the electric wire coatings extrusion process, and the extruded mould of the plastic extruding machine that the outside insulating barrier of parcel electric wire is used is called electric wire lining extrusion extrusion die.The electric wire that goes out to sell on the market much all is a monolayer insulating layer; Insulating material is coated on the outside production technology of electric wire with form of single sheet is called electric wire single layer coating extrusion process, insulating material is coated on the outside production technology of electric wire with double-deck form is called the double-deck lining of electric wire extrusion process.For improving the utilance of waste or used plastics, reduce production costs, now a lot of electric wire manufacturing enterprises adopt double-deck lining extrusion to electric wire, the regenerated plastics that are about to second-rate recovery are overlayed on internal layer, and with the measured primary plastic covering of matter at skin.The double-deck lining of existing electric wire extrusion process mainly contains two kinds of modes; A kind of is to adopt secondary coated extrusion mode; This mode is will reclaim plastic covering earlier at internal layer, uses primary plastic covering at skin again, and this technology mode mainly contains two big shortcomings; The one, there is tangible Separation between internal layer and the skin, in use may produce a layer sliding phenomenon; The 2nd, adopt the secondary extrusion, wasted production man-hour, production efficiency is low, and production cost is higher.Present this production technology is eliminated gradually.Another kind is to adopt disposable lining extrusion mode; This mode is to utilize double-colored or extra quality plastic extruding machine to accomplish disposable lining extrusion, and promptly head is provided with the head of two kinds of plastic passages, and two kinds of plastic raw materials are got into the inner double-layer coextrusion of realizing of head; Though this double-layer coextrusion head production efficiency is higher; But the cost of investment of this double-layer coextrusion head is high, and its price is at present greatly about about 80,000 yuans.
The utility model content:
The technical problem that the utility model will solve is that the deficiency to above-mentioned prior art exists provides a kind of cost of can reducing investment outlay, and can realize the extrusion die of the double-deck lining of electric wire of double-layer coextrusion again.
The technical solution of the utility model is that a kind of extrusion die with double-deck lining of electric wire of following structure is provided.
The double-deck lining of a kind of electric wire extrusion die; Comprise die ontology and be arranged on intrinsic interior injection molding channel, die ontology is a cone table, and interior injection molding channel is a funnel type endoporus; It is characterized in that; The outer wall of die ontology is provided with outer injection molding channel, and outer injection molding channel is made up of injection hole, sprue, outlet opening, and funnel type inner hole wall and interior injection molding channel are passed in outlet in the exit of interior injection molding channel outlet pools an inside and outside conjoint outlet.
The utility model also has following characteristic:
The injection hole of described outer injection molding channel is an axial groove; The sprue of outer injection molding channel by preceding runner with the back runner form, preceding runner is an arc groove, back runner be about two arc grooves; The outlet opening of outer injection molding channel be about 4 cinclides that pass inner hole wall; Before the mid point of runner be communicated with injection hole, the two ends of preceding runner respectively with two after the mid point of runner be communicated with, the two ends of back runner are communicated with two outlet openings that pass inner hole wall respectively.
Before runner, about runner after two, 4 outlet opening be line of symmetry with the axial groove, be symmetrical in the axial groove of injection hole.
After adopting above structure; Compared with prior art, the utlity model has following advantage: because injection molding channel outside cutting has on the outer wall of traditional mould, two kinds of injection molding materials converge in the mould openings end through inside and outside two injection molding channels; Form former raw material ring bag reclaimed materials, realized double-deck while co-extrusion.Thereby improved work efficiency greatly, and such repacking injection mould, its cost only needs about 100 yuan RMB, compares with the double-layer coextrusion head of prior art, has greatly practiced thrift equipment investment cost.
