Description
Technical field
The present invention relates to a kind of electric connector, more particularly to a kind of manufacture craft of cast-type water-proof connector.
Background technology
Water-proof connector generally comprises live wire, plug and is coated on plug with the packet header of electric wire connection point, typically there is public affairs
Female two water-proof connectors being adapted carry out grafting, realize both be connected, it is necessary to ensure to meet after both connect
Certain classification of waterproof, with certain resistance to acids and bases, freedom from vibration, disclosure satisfy that the normal work at various temperature, and not
Easily occur aging, when making, electric wire is attached with plug portion by the electric connection of electric wire first, then passes through cast
Form realize cladding of the packet header for both junctions, to be met after cast packet header can preferably be coated on electric wire and insert
Head, because the material of three is different, therefore the degree of adhesion of three is particularly important, is poured when making, it is necessary to which both are put into plastics
In injection molding tool, in the prior art, note point is on the side wall in packet header, and during cast, colloid is filled in whole from pour point
Individual cavity, during charging is filled, because colloid has higher operating pressure, so as to will timely be molded colloid
It is filled in mould, during injection, colloid is easy to cause electric connection certain impact, it is produced sideslip, from
And the life-span of product is influenceed, after casting complete, after being merged completely in packet header, when breaking sprue gate, packet header can be produced radially
Deformation, the degree of adhesion of gap, bubble, influence packet header and electric wire and plug is easily produced between packet header and electric wire, product is influenceed
The various aspects of performance such as waterproof, resistance to acids and bases.
The content of the invention
It is an object of the invention to provide a kind of manufacture craft of cast-type water-proof connector, it ensure that electric connection is not run
Partially, packet header does not have bubble and space, and performance is stable, ensure that preferable water proofing property, resistance to acids and bases, freedom from vibration.
There is provided following technical scheme：A kind of manufacture craft of cast-type water-proof connector, it is characterised in that including following
Step：
A, electric wire and plug connected as one, it is ensured that both electrical connections；
B, the above-mentioned electric wire being welded as a whole and plug be positioned in the die cavity of injection machine；
C, the sprue gate of injection machine are located at packet header afterbody corresponding with electric wire, be molded length direction of the direction along electric wire to
Extend at plug；
D, start injection, TPE as raw material, is heated to 180 ° with injection machine and realizes plasticizing, injection by packet header using TPE
Pressure be 5-8Mpa, the speed of injection is 5ml/min, untill die cavity is filled up；
E, the pressure progress pressurize for continuing to step d, and natural cooling 30s；
F, the demoulding.
The present invention is further arranged to, and is completed in the state of above-mentioned steps d, e coordinate ultrasonic activation, injection machine
Die cavity on be equipped with ultrasonic activation component.
The present invention has the advantages that：Sprue gate is located at the afterbody in packet header, it is certain it is pressure injection-moulded during,
TPE under plastifying state can be filled along the length where electric wire, without being impacted to electric connection, be entered
And the problem of produce its sideslip, while during the demoulding, afterbody of the sprue gate along packet header is directly broken, do not interfere with bag
Head and electric wire and the degree of adhesion of plug, the setting of ultrasonic wave can be such that TPE is fed during charging uniformly, in pressurize
During cooling, under the pressure effect for coordinating injection machine, coordinate ultrasonic wave to make packet header during solidification, change it
Original cured density, strengthens itself and electric wire and the degree of adhesion of plug, reaches more preferable water proofing property, resistance to acids and bases, freedom from vibration.
Brief description of the drawings
Fig. 1 is the structural representation of die casting in the present embodiment.
Label implication is as follows in figure：1- plugs；2- packet header；21- sprue gates；22- ultrasonic activation components；3- electric wires；31-
Electric connection；4- injection machines；41- die cavitys.
Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
A kind of manufacture craft of cast-type water-proof connector, it is characterised in that comprise the following steps：
A, electric wire 3 connected as one with plug 1 by electric connection 3131, it is ensured that both electrical connections；
B, the above-mentioned electric wire 3 being welded as a whole and plug 1 be positioned in the die cavity 41 of injection machine 4；
C, the sprue gate 21 of injection machine 4 are located at packet header 2 and the corresponding afterbody of electric wire 3, length of the injection direction along electric wire 3
Direction extends at plug 1；
