To achieve the above object, the present invention is using following technical solution：
A kind of electric connector one-shot forming technique, includes following steps：
Step 1：Multiple conducting terminals are put into injection mold, there is movable mould core, movable mould core to have more in the injection mold A positioning region, multiple positioning region position multiple conducting terminals and spaced apart；
Step 2：Conducting terminal positioning after the completion of, injection mould closing, after the completion of molding, lower movable mould core move upwards one away from From, to multiple conducting terminals carry out precompressed, prevent the contact site of multiple conducting terminals from tilting；
Step 3：Injection mold using multiple into being molded by the way of glue point, in injection moulding process, movable mould core activity one downwards Distance, positioning region are detached from multiple conducting terminals, and to mold insulating body, multiple conducting terminals are solid with insulating body produced by insert molding It is scheduled on and forms terminal module together, positioning region is in insulating body；
Step 4：After the completion of terminal module cooling, injection mold demoulding, movable mould core moves downward, and positioning region is made to completely disengage Terminal module；
Step 5：Terminal module is taken out, shielding shell is wrapped on terminal module, is machined.
As a preferred embodiment, the upper surface of the hyoplastron of the insulating body is recessed with is completely disengaged by above-mentioned positioning region Insulating body and the blind hole formed.
As a preferred embodiment, the terminal groove produced by insert molding on the contact site and hyoplastron of the multiple conducting terminal and reveal Go out the lower surface of hyoplastron.
As a preferred embodiment, the fixed part of the contact site end of the multiple conducting terminal is embedded in hyoplastron.
As a preferred embodiment, the injection mold using four into being molded by the way of glue point.
The present invention has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technical proposal Known to：
By movable mould core to carrying out precompressed before conducting terminal and insulating body produced by insert molding, to prevent the contact site of conducting terminal Tilt, and injection mold using multiple into being molded by the way of glue point, keep conducting terminal normotopia degree deviation smaller, to improve Product fine rate；In injection moulding process, a movable distance, positioning region are detached from multiple conducting terminals, make it lower movable mould core downwards Better injection molding.
More clearly to illustrate the structure feature and effect of the present invention, come below in conjunction with the accompanying drawings to this hair with specific embodiment It is bright to be described in detail.

Specific implementation mode
It please refers to shown in Fig. 1 to Fig. 5, that show the moulding process of the preferred embodiments of the invention, including following step Suddenly：
Step 1：Multiple conducting terminals 10 are put into injection mold, there is movable mould core 50, movable mould core 50 in the injection mold With multiple positioning regions 51, multiple positioning region 51 by multiple conducting terminals 10 position and it is spaced apart；
Step 2：After the completion of conducting terminal 10 positions, injection mould closing, after the completion of molding, lower movable mould core 50 moves upwards One distance carries out precompressed to multiple conducting terminals 10, prevents the contact site 11 of multiple conducting terminals from tilting；
Step 3：Injection mold is using multiple into being molded by the way of glue point, and in injection moulding process, lower movable mould core 50 is living downwards A dynamic distance, positioning region 51 are detached from multiple conducting terminals 10, and to mold insulating body 20, multiple conducting terminals 10 and insulation are originally 20 produced by insert molding of body is fixed together to form terminal module 30, and positioning region 51 is in insulating body 20.
Step 4：After the completion of terminal module 30 cools down, injection mold demoulding, lower movable mould core 50 moves downward, and makes positioning Portion 51 completely disengages terminal module 30.
Step 5：Terminal module 30 is taken out, shielding shell 40 is wrapped on terminal module 30, is machined.
Above-mentioned injection mold is using four into glue, tradition relatively is single into glue point into glue mode, conductive by the way of glue point 10 normotopia degree of terminal narrows down to 0.04MAX by original 0.08MAX, and 10 contact site of conducting terminal, 11 lid glue is by original 0.12MAX narrows down to 0.06MAX；Make the connector quality higher that it is made, improves product fine rate.
The upper surface of the hyoplastron 21 of the insulating body 20 be recessed with insulating body 20 is completely disengaged by above-mentioned positioning region 51 and The blind hole 201 of formation.The contact site 11 of the multiple conducting terminal and 211 produced by insert molding of terminal groove on hyoplastron 21 simultaneously expose tongue The lower surface of plate 21.The fixed part 12 of 11 end of the contact site is embedded in hyoplastron 21.
The design focal point of the present invention is：
By movable mould core to carrying out precompressed before conducting terminal and insulating body produced by insert molding, to prevent the contact site of conducting terminal Tilt, and injection mold using multiple into being molded by the way of glue point, keep conducting terminal normotopia degree deviation smaller, to improve Product fine rate；In injection moulding process, a movable distance, positioning region are detached from multiple conducting terminals, make it lower movable mould core downwards Better injection molding.
The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention, Therefore it is every according to the technical essence of the invention to any subtle modifications, equivalent variations and modifications made by above example, still Belong in the range of technical solution of the present invention.
