The cross sectional shape for stating sealing wire 15 is formed as triangular structure.
Due to defining sealing wire 15 by ultrasonic bonding between kernel 11 and outer core 2, therefore, it can replace interior completely
The traditional bonded structure adopted between core 11 and outer core 2 and its technique, so as to effectively improve kernel 11 and outer core 2 it
Between assembling production efficiency.In order to improve the firm welding reliability between outer core 2 and kernel 11, and ensure outer core 2 and kernel
The cross sectional shape of the 3rd lobe 110 generally, is designed to trapezium structure by the sealing reliability between 11, by described
The cross sectional shape of two excessive glue grooves 14 is also designed to trapezium structure, it is preferable that the cross sectional shape of the second described excessive glue groove 14 is in straight
Angle trapezium structure, as shown in Figure 5.
As shown in figure 1, described outer core 2 is fixedly connected in 1 inner chamber of cup, is formed between cup 1 and outer core 2 and reclaimed
Runner 9, the recovery runner 9 are communicated with central canal 10.Preferably, several distributions of ring outer core 2 can be formed on outer core 2
Buckle 21, several described buckles 21 are preferably ring outer core 2 and are uniformly distributed.The outer core 2 can be by buckle 21 and cup 1

8 one end are covered through 3 inner chamber of upper cover, and integral structure is fixedly connected into by positioning convex tendon 31 between lower cover 8 and upper cover 3, such as
Shown in Fig. 8, also formed by positioning convex tendon 31 between lower cover 8 and upper cover 3 and reclaim the fluid passage that runner 9 is communicated, such as Fig. 1
It is shown.Preferably, described lower cover 8 forms over-surplus fit structure respectively between some positioning convex tendons 31.
Generally, the raw material of the upper cover 3 is PP material, and lower cover 8 is then PC material, if led to upper cover 3, lower cover 8 respectively
Assembled after crossing injection mo(u)lding again, necessarily cause its production process complex, reduce the dress between upper cover 3 and lower cover 8
With working performance, and the resource such as waste of manpower, material resources.
In order to lift the assembling work efficiency between upper cover 3 and lower cover 8, according to upper cover 3, the construction featuress of lower cover 8, assembling
The factors such as relation, can adopt the moulding process of dijection molding come so that the one formed a fixed connection between lower cover 8 and upper cover 3
Change structure, also, after first time injection mo(u)lding, directly form lower cover 8, as shown in figure 11.Then, is carried out in lower cover 8
Secondary injection molding, directly forms upper cover 3, and upper cover 3 is coated in lower cover 8, as shown in figure 12.Thus, it is possible to so that upper cover
3rd, integrated molding structure is formed between positioning convex tendon 31, lower cover 8, so as to greatly simplifie the production work of upper cover 3, lower cover 8
Skill, and then the assembling work efficiency between upper cover 3 and lower cover 8 is significantly lifted, and saved the money such as human and material resources
Source.
In order to better ensure that the shaping efficiency of upper cover 3, lower cover 8, and be conducive to lifting upper cover 3, the molding matter of lower cover 8
Amount, generally, in described first time injection mo(u)lding, its Mold Temperatures set be 280 DEG C, 290 DEG C, 300 DEG C, 310 DEG C or
320 DEG C, its briquetting pressure is set as 115Bar, 110Bar, 105Bar, 100Bar, 95Bar, 90Bar or 85Bar, after molding
Dwell time be 3 ± 2s.In second described injection mo(u)lding, its Mold Temperatures set be 180 DEG C, 190 DEG C, 200 DEG C,
210 DEG C or 220 DEG C, its briquetting pressure is set as 85Bar, 80Bar, 75Bar, 70Bar, 65Bar, 60Bar or 55Bar,
Dwell time after molding is set as 3 ± 2s.Generally, its Mold Temperatures set is higher, then its corresponding briquetting pressure setting compared with
It is low.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, it is noted that all
