Secondary injection molding may further include with forming the sub-step of the second insulation glue-line:
The injection of second fluid sizing material is placed with to the second molding die of the header body that first time injection molding is completed
In；
The second fluid sizing material is suppressed, is shaped to the second insulation glue-line after cooling plasticizing.
In the embodiment of the present application, second of injection molding can be carried out using the micelle of polypropylene material.Having
During body is realized, the mode of operation and principle of second of injection molding are substantially similar with first time injection molding, can pass through
Polypropylene micelle is heated to obtain polypropylene fluid sizing material, and then assembling is placed with using polypropylene fluid sizing material injection
In the second molding die for having the header body of stainless steel iron-clad and the first insulation glue-line, sizing and solidifying is obtained after repressed cooling
Second insulation glue-line.
It should be noted that since second of injection molding is different from sizing material material used by first time injection molding,
Therefore, need to adjust forming temperature, pressure, time in concrete operations to reach optimal molding effect.
In the embodiment of the present application, it when using the micelle of polypropylene material, is heated by injection molding machine and obtains polypropylene
When fluid sizing material, upper section temperature be can control between 180-190 DEG C, and middle section temperature can control between 185-195 DEG C, and
Lower section temperature then can control between 195-205 DEG C；In addition, when liquid sizing material is entered in molding die cavity by pressure,
Adjustable stagnation pressure is in 80-120Kg/cm2Between range, low pressure is adjusted in 5-20Kg/cm2Between range, and a pressure can then be controlled
System is in 35-45Kg/cm2Between range, two voltage-controlled systems are in 5-15Kg/cm2Between range；And at the time of molding between control on, can be with
The second fluid sizing material for controlling melting enters the time of molding die cavity from nozzle as 3s, and then cooling 4s solidification is qualitative,
It is opened sampling again.
Sub-step 5042 carries out third time using third molding die and is molded into after forming the second insulation glue-line
Type.
In general, the plug for being equipped with the first insulation glue-line, hard shell and the second insulation glue-line had it is certain strong
Degree, can better meet the requirement in routine use for plug hardness.But if with biggish second insulating cement of hardness
Surface of the layer as plug, it is easy in use causing the damage of plug due to colliding with etc., in the embodiment of the present application
In, after glue-line is insulated in formation second, third time injection molding can also be carried out to the plug using the lower material of hardness,
To protect inner layers insulation glue-line and header body.
Therefore, described after forming the second insulation glue-line, third time injection molding is carried out using third molding die
Sub-step may further include:
The injection of third fluid sizing material is placed in the third molding die for the header body for having formed the second insulation glue-line；
The third fluid sizing material is suppressed, third insulation glue-line is shaped to after cooling plasticizing.
In the embodiment of the present application, the third fluid sizing material can be thermoplastic elastomer (TPE) fluid sizing material.Thermoplastic elastomehc
Property body be a kind of high resiliency with rubber, high-intensitive, high resilience, but have can injection molding feature material, use
The third insulation glue-line of thermoplastic elastomer (TPE) production facilitates the first insulation glue-line and the second insulating cement of protection cladding in the inner
Layer.
In the concrete realization, the mode of operation and principle of the third time injection molding are the same as first time injection molding and second
Secondary injection molding is substantially similar, can be by heating to obtain thermoplastic elastic fluid sizing material, in turn to thermoplastic elastic micelle
Using in thermoplastic elastic fluid sizing material injection third molding die, sizing and solidifying obtains third insulation after repressed cooling
Glue-line.
It should be noted that since third time injection molding and first time injection molding and second of injection molding are used
Sizing material material it is different, therefore, need to adjust forming temperature, pressure, time in concrete operations is imitated with reaching optimal molding
Fruit.
In the embodiment of the present application, it when using the micelle of thermoplastic elastic material, is heated by injection molding machine and obtains heat
When Plastic resilient fluid sizing material, upper section temperature be can control between 160-170 DEG C, and middle section temperature can control in 170-180
Between DEG C, and lower section temperature then can control between 175-185 DEG C；In addition, liquid sizing material enters molding die by pressure
When in cavity, adjustable stagnation pressure is in 80-120Kg/cm2Between range, low pressure is adjusted in 5-20Kg/cm2Between range, and one
Pressure then can control in 40-50Kg/cm2Between range, two voltage-controlled systems are in 20-30Kg/cm2Between range；And at the time of molding between
In control, the third fluid sizing material that can control melting enters the time of molding die cavity from nozzle as 3s, then cools down
4s solidification is qualitative, then is opened sampling.
It should be noted that for simple description, therefore, it is stated as a series of action groups for embodiment of the method
