Abstract
The utility model relates to an extrusion molding mold for electric wires and cables, which comprises a mold sleeve and a mold core. In the utility model, the inlet part of the mold sleeve is a straight cylinder (3); the tail of the mold core is provided wit a circle table one (4) and a circle table two (5); the circle table one can be just inserted in the straight cylinder (3) on the inlet of the mold sleeve causing the mold sleeve and mold core to be sheathed and connected together; the diameter of the circle table two (5) is consistent with the outside diameter of the mold sleeve; the tail of the mold core is provided with a plurality of evenly distributed holes (6) which can be passed by insulating plastic. When the utility model is used for production, plastic is extruded in the mold through the mold core and is extruded out from an extruding opening. The utility model can naturally satisfy the concentricity of the mold sleeve and the mold core, causes the pressure of insulating plastic in the mold to be more uniform and can not generate an eccentric phenomenon.
Description
The utility model relates to a kind of extruded mould of producing electric wire, belongs to electric wire production equipment field.
Wire cable insulating extrusion process and special-purpose plastic extruding machine thereof according to a large amount of employings at present when producing the electric wire of certain specification, need to change the mould of corresponding specification.Disclose a kind of method that can reduce the die change number of times although application number is 01130448.0 patent application, regular more mold exchange remains essential.
The electric wire extruded mould is divided into core rod and separated two parts of die sleeve.The electric wire plastic extruding machine of present various models, its core rod and die sleeve are designed to non-contacting.Core rod and die sleeve are separately fixed on the core rod connector and die sleeve connector on the head, make to form a cavity runner between core rod and the die sleeve, and ambroin forms certain thickness plastics blank pipe by the cavity runner, are wrapped in and form insulation on the core.For guaranteeing that eccentric phenomena does not take place electric wire, requiring has extraordinary concentricity between core rod and the die sleeve, and the adjusting of concentricity is to realize by the special adjusting screw(rod) that designs on the head.Common way is to start the machine, the electric wire produced is cut, by measure the electric wire cross section everywhere insulation thickness judge eccentric degree, regulate the adjusting screw(rod) on the head again, by measurement and adjusting repeatedly, till the concentricity of core rod and die sleeve meets the demands.Its major defect is time-consuming expense material, and when being full of Insulation Material in die cavity, it is very hard pulling screw, screw and spiral shell is buckled often to keep in repair also be essential.Certainly, use up mould after, at high temperature dismantle its also trouble.
The purpose of this utility model just is to design a kind of need not the adjusting, can satisfy concentricity requirement naturally, insulated wire cable production mould simultaneously for convenience detach.
The utility model is realized in the following way: the utility model comprises core rod and die sleeve two parts composition, and design has one section straight cylinder in the die sleeve porch; Afterbody design at core rod has the second order round platform, round platform one diameter is less, and round platform two diameters are bigger, makes all or part of straight cylinder that just in time injects the die sleeve arrival end of the rank round platform of winning, the diameter of the second rank round platform and die sleeve external diameter are consistent, and closely contact with the extruder head cavity; On the second order round platform of core rod afterbody, uniform Design has a plurality of holes of passing the second order round platform vertically.
The mould of this design can satisfy described requirement.
Further specify this use is novel with reference to the accompanying drawings below.
Fig. 1: the core rod of existing mold and the master of die sleeve look cutaway view
Fig. 2: existing mold is in the assembling of extrusion head
Fig. 3: core rod of the present utility model and die sleeve master look cutaway view
Fig. 4: the left view of core rod of the present utility model
As shown in Figure 1, the core rod external diameter of existing mold is little more a lot of than die sleeve external diameter, when assembling as shown in Figure 2, core rod does not all contact with die sleeve with the cavity of extrusion head, be fixed in the head cavity by the core rod connector (1) on the head, die sleeve is fixed on the die sleeve connector, forms a cavity runner between die sleeve and the core rod.In the production process, the line heart passes core rod and die sleeve, and ambroin is by the cavity runner, pressurized is extruded from extrusion, form insulation on line,, must allow the axle center of core rod and die sleeve be on same the straight line for guaranteeing the unanimity of insulation thickness everywhere of ambroin at core.Existing method is to regulate die sleeve by regulating the adjusting screw(rod) (2) that designs in advance on the head, and the axle center of die sleeve and core rod is on same the straight line.As previously mentioned, this adjusting operating process quite bothers.
As shown in Figure 3, die sleeve intake section of the present utility model is one section straight cylinder (3), and the size design of the round platform one (4) of core rod afterbody is consistent with straight cylinder (3) internal diameter, and the height of round platform one (4) can be bigger slightly than the height of straight cylinder.During use, core rod is inserted die sleeve, combine closely between round platform one and the die sleeve, therefore guaranteed the concentricity of die sleeve and core rod naturally.Round platform two (5) diameters of core rod afterbody are consistent with the die sleeve external diameter simultaneously, and die sleeve and core rod are stuck in the cavity of extrusion head simultaneously, and core rod and die sleeve can not become flexible.
In process of production, ambroin is not to flow directly in the mould, but flows to mould by the equally distributed hole of core rod afterbody (6) under the effect of head internal pressure, extrudes through the extrusion molding mouth again.Plastic pressure is more even everywhere in the mould like this, and the uneven situation of plastic pressure in the head is played certain insulating effect, and is more even thereby plastics are extruded, and improved product quality.
The utility model mould is nested together die sleeve and core rod earlier in use, makes the as a whole head of putting into and just can use, and need not fix by connector, simultaneously, satisfies concentricity requirement naturally.After production finishes, mold integral is taken out in head, core rod and die sleeve are separated, clear up residual plastics more respectively, avoid at the enterprising line operate of the head of high temperature.
Of the present utility model one more execution mode be the groove (7) that on die sleeve and core rod, designs an annular respectively.After being to use, its purpose can very easily die sleeve and core rod be separated.
Claims (2)
1, a kind of extruded mould of producing electric wire comprises two parts of die sleeve and core rod, it is characterized in that: the entry design of die sleeve is one section straight cylinder (3); The afterbody design of core rod has round platform one (4) and round platform two (5), round platform one (4) just in time can insert in the straight cylinder (3) of die sleeve inlet, and die sleeve and core rod are closely connected together, and round platform two (5) diameters are consistent with the die sleeve external diameter; The design of core rod afterbody has a plurality of equally distributed holes (6) that supply ambroin to pass through.
2, extruded mould as claimed in claim 1 is characterized in that, an annular groove (7) is arranged respectively on die sleeve and core rod.
