Abstract
The utility model discloses a die for making a halogen-free low-smoke polyolefin cable. The die comprises a die body and a conical die cavity which is formed on the die body and is characterized in that: a strip-shaped feeding hole is formed at the middle position of the die cavity close to an outer side; and a main insert and a branch insert are arranged on both sides and are used for fixing cables at two ends and preventing an injection molding material from overflowing. The feeding hole is directly communicated with the cavity body of the die cavity, and the injection molding material flows into the die cavity from the feeding hole and flows towards the left side and the right side of the die from the middle, so that an injection molding distance is shortened. The die has a novel structure and an artful design; a produced connecting body is attractive, neat, bright and clean, and has a smooth surface; and moreover, the insulated cross section of the die is free from air holes and the reduction rate of the tensile strength of a compressed and connected conductor is low, so that the injection molding material is saved and the production cost is lowered.
Description
Technical field
The utility model relates to mfg. moulding die, relates in particular to the mould that is used to make the low smoke, zero halogen polyolefin cable.
Background technology
The charging aperture of the mould of traditional fabrication low smoke, zero halogen polyolefin cable is that injection molding material is flowed to left side die cavity from the centre, flows to the right die cavity by left side die cavity again.This process looks quite reasonable, and actually this is not so, in whole injection moulding process, needs sizable injection pressure, also need quite high injection temperature, pressure is big, and equipment holds can't stand, the temperature height be easy to generate incipient scorch, so the connector of producing, outward appearance is crude, and is rough.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of mould that is used to make the low smoke, zero halogen polyolefin cable, helps reducing the injection moulding distance, has reduced injection pressure, also reduced injection temperature, the cable connector smooth surface of producing.
To achieve these goals, the technical solution of the utility model is as follows:
Be used to make the mould of low smoke, zero halogen polyolefin cable, comprise die ontology and be arranged on die cavity above the die ontology.
Four jiaos of correspondences of described die ontology are provided with the installing hole of four circles, are convenient to the fixedly position of production mould;
Be characterized in that the centre position of described die cavity is provided with the charging aperture of strip in the outer part, described charging aperture directly is communicated with the cavity of die cavity, and injection molding material flows into die cavity from described charging aperture like this, flows to the right and left of mould then from the centre.
The both sides of described die cavity are provided with main insert and branch inserts respectively, and their effect has two: the one, and the fixing cable at two, the 2nd, stop overflowing of the interior injection molding material of die cavity.
Further, described master inserts to insert with branch and is connected mutually with the cavity two ends in described film chamber respectively.
It is low that the insulation profile pore-free of above-mentioned mould, compression connect back conductor tensile strength rate of descent, is equivalent to save injection molding material, reduced production cost.
Further, it is conical that the cavity of described die cavity is, and is to form by inwardly offer groove by table on mould;
The both sides of described die cavity are provided with heating tube front and back mould, are used to produce the heating body.
The beneficial effects of the utility model are, in the middle of charging aperture is arranged on, injection molding material from the die cavity intermediate flow to both sides, reduced the injection moulding distance, effectively reduce injection pressure and temperature, the cable connector good looking appearance of producing, neat bright and clean, smooth surface meet national standard.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the vertical view corresponding with Fig. 1.
Among the figure, 1, charging aperture, 2, die cavity, 31, the heating tube front mould, 32, mould behind the heating tube, 33, branch inserts, 34, main inserting, 41, installing hole, 42, installing hole, 43, installing hole, 44, installing hole, 5, die ontology;
Embodiment:
Be easy to understand understanding in order to make creation characteristic of the present utility model, technological means and to reach purpose, further set forth the utility model below in conjunction with specific embodiment.
Embodiment:
Referring to Fig. 1, be used to make the mould of low smoke, zero halogen polyolefin cable, comprise die ontology 5 and be arranged on die cavity 2 above the die ontology 5.
The centre position of die cavity 2 is provided with the charging aperture 1 of strip in the outer part, and described charging aperture 1 is connected with the cavity of die cavity 2, and injection molding material flows into die cavity 2 from described charging aperture like this, flows to the right and left of mould then from the centre.
The left and right sides of die cavity 2 is provided with branch respectively and inserts and 33 insert 34 with main, is connected with the cavity of die cavity 2, and effect mainly is overflowing of the cable at fixedly two and the interior injection molding material of cavity that stops die cavity 2.
And, the insulation profile pore-free of mould, it is low that compression connects back conductor tensile strength rate of descent, is equivalent to save injection molding material, reduced production cost.
It is conical that the cavity of die cavity 2 is, and is by offer groove shaped inwards by table on mould.
The both sides of die cavity 2 are provided with mould 32 behind heating tube front mould 31 and the heating tube respectively, are used to produce the heating body.
Four jiaos of correspondences of die ontology 5 are provided with the installing hole 41,42,43 and 44 of four circles, are convenient to the fixedly position of production mould;
By the cable connector good looking appearance that above-mentioned Mold Making goes out, neatly bright and clean, smooth surface meets national standard; And can effectively save injection molding material, reduced production cost.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
