The invention relates to an auxiliary device for submerged injection molding, in particular to a metal strip for auxiliary submerged injection molding.

In the process of manufacturing a connector, an insert molding process is often used to form the connector as shown in FIG. 1, a plurality of metal terminals 2 are first put into the mold, and then the latch The piece 4 is also put into the mold, and then injection-molded to form a plastic casing 6 so that the metal terminal 2 and the locking member 4 are fixed in the casing 6.

However, due to the large number of metal terminals 2, the process of putting in the mold is quite time-consuming, and the placement of the metal terminals 2 is not accurate, which often causes damage to the mold, and due to the time-consuming process, there is also a problem of reduced production capacity.

In view of this, the object of the present invention is to provide a metal tape for auxiliary injection molding, the metal tape moves along the production line, and upstream of the mold, a plurality of terminals for the connector can be positioned on the metal tape first Then, the metal strip moves so that a plurality of terminals can be accurately placed in the mold at the same time. After injection molding, the formed connectors (including terminals, latches and plastic shells) are moved to the mold by the metal strip Downstream of the cable, and then remove the formed connector from the metal strip.

An embodiment of the metal belt for auxiliary injection and injection molding according to the present invention includes a plurality of positioning units, and each positioning unit includes: a body, a positioning portion, and two side plates. The positioning part is formed on the body and has a plurality of positioning slots, the positioning slots are arranged parallel to each other, the side plates are respectively disposed on opposite sides of the positioning part, each side plate of the side plates has a plurality of slots , The slots correspond to the positioning slots.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following examples are given in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of the connector after molding.

FIG. 2 is a perspective view of an embodiment of the metal tape for auxiliary injection molding according to the present invention.

FIG. 3 is a side view of the metal strip with the terminal positioned in the auxiliary injection molding of the present invention.

Fig. 4 is a perspective view of the metal band for auxiliary injection molding according to the present invention loaded with a connector after molding.

FIG. 5 is a perspective view of a metal tape for auxiliary injection/injection molding of the present invention loaded with a molded connector from another angle.

Referring to FIG. 2, the metal strip 100 for auxiliary injection molding according to the present invention includes a plurality of positioning units 10. Two opposite sides of each positioning unit 10 of these positioning units 10 are adjacent to the other two positioning units 10. A band structure is formed (see FIGS. 4 and 5). Each positioning unit 10 includes a body 12, a positioning portion 14 and two side plates 16 and 18. The positioning portion 14 is formed on the body 12 and has a plurality of positioning slots 142. The positioning slots 142 are arranged parallel to each other. The two side plates 16 And 18 are respectively disposed on opposite sides 141 and 143 of the positioning portion 14, the side plate 16 has a plurality of slots 162, side The board 18 has a plurality of slots 182, and the slots 162 and the slots 182 correspond to the positioning slots 142. The side plates 16 and 18 stand upright from the two sides 141 and 143 of the positioning portion 14, respectively. In this embodiment, the side plates 16 and 18 are perpendicular to the positioning portion 14. The slot 162 communicates with the upper edge of the side plate 16. Similarly, the slot 182 communicates with the upper edge of the side plate 18. A first through hole 13 is formed in the body 12 and adjacent to the positioning portion 14, a second through hole 15 is formed in the body 12 and adjacent to the positioning portion 14, and the positioning portion 14 is located in the first through hole 13 and the second through Between the holes 15, that is, the first through holes 13 and the second through holes 15 are respectively adjacent to the opposite sides 141 and 143 of the positioning portion 14, the area of the first through holes 13 is larger than the area of the second through holes 15, The side plate 16 is located between the first through hole 13 and the positioning portion 14, and the side plate 18 is located between the second through hole 15 and the positioning portion 14. Each positioning unit 10 is provided with a pair of hooks 19 for clamping on the production line.

As shown in FIG. 3, the terminal 20 used for manufacturing the connector is first placed on the positioning unit 10, the positioning end 22 of the terminal 20 is inserted into the positioning slot 142 of the positioning portion 14 and is positioned in the positioning slot 142, At the same time, the plug end 21 of the terminal 20 extends through the slot 162 of the side plate 16 into the first through hole 13, and the soldering end 23 of the terminal 20 extends through the slot 182 of the side plate 18 into the second through hole 15. Each terminal 20 can be positioned on the positioning portion 14 of the positioning unit 10 and arranged in parallel with each other according to a set distance.

The terminal 20 that has been positioned moves to the mold with the metal strip 100 and is placed at the desired position in the mold, and then the locking member 40 is also placed in the mold, followed by injection molding, between the terminal 20 and the locking member 40 A plastic casing 60 is formed at the location so that the terminal 20 and the locking member 40 are combined with the plastic casing 60, as shown in FIGS. 4 and 5. Finally, the metal strip 100 moves away from the mold, and then the terminal 20 and the locking member 40 combined with the plastic housing 60 can be removed from the metal strip 100.
