pushed into male die core 40 to moulding 10, i.e. three 47 rightings of the first male model pin, three mouldings 10 are smoothly planted together Enter in male die core 40, wherein when first, second, the of the first, second master mold mold insert 31,32 and the male die core 40 of mother module core 30 Three, when Four-slider mold insert 41,43,42,44 contacts, i.e., when mother module core 30 and male die core 40 mold completely, three first public The distance A that mould pin 47 arrives the second master mold mold insert 32 of mother module core 30 is 0.2 millimeter, the thickness of the docking section 13 to moulding 10 It is 0.6 millimeter, this distance A is less than the thickness of the docking section 13 to moulding 10, i.e. a part of docking section 13 is taken in second What is be arranged corresponding to master mold mold insert 32 is interior to moulding container (not shown), and another part of docking section 13 protrudes out the second mother Mould mold insert 32 is corresponding be arranged to moulding container, i.e., do not completely disengage out the to the docking section 13 of moulding 10 at this time Two master mold mold inserts 32 are corresponding be arranged to moulding container, i.e., to the docking section 13 of moulding 10 always in 30 institute of mother module core Be correspondingly arranged to be moved in moulding container, there is no because third, the four, the five, the 6th master mold mold inserts 33,34, 35,36 release inertia and cause the docking section 13 to moulding 10 to completely disengage the second master mold mold insert 32, therefore, described three The setting of first male model pin 47 avoids when moulding 10 is in male die core 40 and the molding completely of mother module core 30 because to moulding 10 docking section 13 2 times enters the second master mold mold insert 32 of mother module core 30 and causes the docking section 13 to moulding 10 by second Master mold mold insert 32 weighs wounded；(6) it is formed by single injection-molded and is coated on three plastic parts 20 to 10 periphery of moulding, work as note After the completion of modeling, the decorporate mother module core 30 and the male die core 40.

In conclusion the utility model has the following beneficial effects: the plastic parts 20 of (1) connector 100 is equipped with through-hole 25, the through-hole 25 is that the first male model pin 47 exits plastic parts 20 and is formed by after the completion of plastic parts 20 forms, and is being molded The first male model pin 47 treats moulding 10 when moulding 10 is inserted into male die core 40 and carries out righting in the process, avoids wait be molded Part 10 causes to take off completely to moulding 10 due to the release inertia of third, the four, the five, the 6th master mold mold inserts 33,34,35,36 Mother module core 30 out, wait for causing into mother module core 30 for moulding 10 2 times when molding completely so as to cause mother module core 30 with male die core 40 It is weighed wounded to moulding 10 by mother module core 30；(2) in mould filling, the first male model pin 47 is used to support to moulding 10, is prevented Only to moulding 10 due to being deformed by stuffing pressure；(3) to moulding 10 after being molded due to mother module core 30 and male die core 40 13 part of docking section take in mother module core 30, so, first planted before male die core 40 is molded with mother module core 30 to moulding 10 Enter mother module core 30, it can be to avoid due to causing in clamping process to 10 size of moulding and orientation problem to moulding 10 2 It is secondary to enter mother module core 30 and cause to be weighed wounded to moulding 10 by mother module core 30, it is also possible to which control waits for moulding 10 well With the fit clearance of mother module core 30, avoid occurring the case where to 10 top surface lid glue of moulding in injection molding process.

Above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to preferred embodiment pair The utility model is described in detail, those skilled in the art should understand that, it can be to the technology of the utility model Scheme is modified or replaced equivalently, without departing from the spirit and scope of the technical scheme of the present invention.
