Description
Technical field
The utility model relates to a kind of cable insulation and extrudes self-centering head and mould.
Background technology
Cross-head is the modal equipment of wires and cables industry, it is also the important structure member of extruder, the molten plastic that its effect is mainly extruder becomes rectilinear motion by screw, the single stage plastication of going forward side by side, produce necessary briquetting pressure, the assurance plastic is closely knit, thereby obtains the consistent continuous section bar of cross sectional shape.Due to traditional cross-head complex structure of existing equipment, operating difficulties changes inconvenience, and easy generation is the phenomenons such as glue, leakage material, bias, has had a strong impact on the quality of cable product.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and operation changes conveniently, has greatly improved operating efficiency, has reduced waste of raw materials, can effectively guarantee self-centering head and the mould of cable product quality.
To achieve these goals, the technical solution of the utility model is: provide a kind of cable insulation to extrude the self-centering head, wherein, comprise die sleeve, core rod, die sleeve seat, front sprue, core rod, shunting comb, square toes and rear sprue; Crosshead body is square toes and neck interference fit and the structural member that is welded as a whole, and the shunting comb is located at the core rod top, and square toes are located at shunting comb top, and neck is located at the square toes tops; Be provided with dive key between shunting comb and core rod, rear sprue four jiaos countersunk seat is set, be fastened on square toes with four socket cap screws, fastening and the pressure die block set of front sprue, offer circular hole directly over the close front sprue of square toes, form the material runner between the straight-through square toes of circular hole and shunting comb; Core rod and core rod cone match are installed, and round nut pushes up die sleeve and is pressed in the die sleeve seat.
Self-centering head and the mould extruded of the present utility model, the head outward appearance is square, and right-angle structure is provided with machine neck, head, three sections heating collars of discharging opening.Depend on and be contained in that on fuselage, a pair of Hough folder with heater is connected head with fuselage.Square toes and neck interference fit also are welded as a whole, rear sprue four jiaos countersunk seat is set, having increased dive key guarantees not rotate when regulating core rod, round nut pushes up die sleeve and is pressed in the die sleeve seat, screw or position that the round nut that gets loose can the level modulation die sleeve, no matter die sleeve is in any position, and the joint portion of die sleeve seat and die sleeve " dead angle " can not occur.This head also can be configured on the extruder of larger screw diameter, possesses the function that extrudes the colour code Double-colour horn wire; Just can realize extruding insulating barrier has more uniform monolateral thickness needn't to regulate mould during use, easily controls eccentric; Core rod and core rod are taked cone match, easily suppress to leak material.
Description of drawings
Fig. 1 is the structural representation that the utility model cable insulation is extruded the self-centering head;
In figure: 1, round nut; 2, die sleeve; 3, core rod; 4, die sleeve seat; 5, front sprue; 6, core rod; 7, shunting comb; 8, square toes; 9, little round nut; 10, circular big nut; 11, dive key; 12, rear sprue; 13, neck.
Embodiment
Extrude the technology contents, structural feature of self-centering head in order to describe the utility model cable insulation in detail, below in conjunction with execution mode and coordinate accompanying drawing to be described further.
Embodiment one
As shown in Figure 1, the utility model cable insulation is extruded the self-centering head, comprises die sleeve 2, core rod 3, die sleeve seat 4, front sprue 5, core rod 6, shunting comb 7, square toes 8 and rear sprue 12; Shunting comb 7 is located at core rod 6 tops, and square toes 8 are located at shunting comb 7 tops, and neck 13 is located at square toes 8 tops; Be provided with dive key 11 between shunting comb 7 and core rod 6, crosshead body is square toes 8 and neck 13 interference fit and the structural member that is welded as a whole.Rear sprue 12 four jiaos establish countersunk seat, be fastened on square toes 8 with four socket cap screws, make shunting comb 7 location, and be convenient to dismounting.Circular big nut 10 screws in the screw thread of shunting comb 7 tail ends; The circular big nut 10 of forward, core rod 6 is protracted.During counter-rotating, it withstands and is contained in two on the core rod 6 roundlet nuts 9 that can lock mutually core rod 6 is retreated.Dive key 11 guarantees not rotate when regulating core rod 6.
Discharge end, four bolts borrowed equally by front sprue 5 and square toes 8 are fastening and pressure die block set 4.Adjust eccentric bolt in order to fine setting bias under special fortuitous event for four that remain with traditional structure on front sprue 5.Open the material runner of the straight-through square toes 8 of circular hole and 7 formation of shunting comb directly over square toes 8 close front sprue 5 ends; When extruding the colour code insulating barrier, by vertical colour code extruder hole injecting material from then on.When extruding monochromatic insulation, the plunger shape screw of available configuration is blocked the colour code mouth.
Embodiment two
As shown in Figure 1, core rod 3 is installed with core rod 6 cone match, can easily it be packed into from front end; Borrow the centre bore of core rod 6 also to be easy to it is ejected.When extruding, the viscous state material stream with certain pressure intensity exists core rod level pressure backward in core rod 3 and 2 tapered runners of die sleeve, makes core rod stably be in the normal position; The conical surface that presses cooperation is effectively prevented from the joint portion to core rod centre bore blowdown.Round nut 1 pushes up die sleeve 2 and is pressed in die sleeve seat 4.The tapering of die sleeve 2 and die sleeve seat 4 inner conical surfaces can be identical, also can be different.According to the expressing technique requirement, screw or position that the round nut 1 that gets loose can level modulation die sleeve 2.No matter die sleeve 2 is in any position, and die sleeve seat 4 " dead angle " can not occur with the joint portion of die sleeve 2.
The utility model cable insulation is extruded the self-centering head and is applicable to the products such as low tension wire, low-voltage cable, 10kV crosslinked cable, suspended insulated guide wire, low pressure flame retardant cable or 10kV flame-proof cross-linking cable.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
