Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to an injection mold for connectors. Background Art

[0002] A high-speed cable is a cable for low-cost short-distance connection and used for data transmission, and is widely applied to data center interconnection scenarios such as SATA storage devices, RADI system scenarios, core routers, and Ethernet. As a high-speed and stable data transmission medium, the high-speed cable brings great convenience to people's work and life. Generally, a high-speed cable includes a cable body and a connector connected to the end of the cable. According to different transmission protocols, common high-speed cables include types such as SFP, QSFP, OSFP, and SAS. Taking the SAS cable as an example, in the production process, it is necessary to connect the cable part and the circuit board part of the corresponding connector, that is, to strip the outer skin at the end of the cable, and then connect the exposed inner core part to the circuit board part of the connector. After the cable and the connector are connected, it is necessary to set a shell at the connection part. Generally, the shell is made of plastic material and plays a role in protection and insulation. To ensure the stability of the shell structure, in the traditional production process, generally, the shell is separately manufactured and then assembled onto the connector. However, such a method increases the production process and involves more material transfer processes, resulting in a more cumbersome processing process for the connector. Therefore, a mold capable of forming a shell around the cable and the connector is needed. Content of the Utility Model

Specific embodiments

[0022] To facilitate the understanding of the present utility model by those skilled in the art, the present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0023] Referring to Figures 1 to 4 , this embodiment provides an injection mold for a connector 7, including a base 1, die feet 11 provided on the base 1, a lower die 2 provided on the die feet 11, an upper die 3 provided on the lower die 2, a top plate 4 provided on the upper die 3, and a die bar 5 provided on the top surface of the lower die 2.

[0024] The lower die 2 is provided with a first forming concave part 21. One side of the bottom surface of the first forming concave part 21 is provided with a first forming table 22. A first groove 23 for the cable to pass through is provided at the position corresponding to the first forming concave part 21 on the top surface edge of the lower die 2. The bottom surface of the upper die 3 is provided with a second forming concave part 31 corresponding to the first forming concave part 21. A second forming table 32 corresponding to the first forming table 22 is provided on the bottom surface of the second forming concave part 31. A second groove is provided at the position corresponding to the first groove 23 on the bottom surface of the upper die 3. The first forming concave part 21 and the second forming concave part 31 together form a forming cavity for the connector 7 housing. The connector 7 housing processed by the present utility model has a stepped structure (as shown in Figure 4 ), and the stepped structure of the connector 7 housing can be formed under the cooperation of the first forming table 22 and the second forming table 32.

[0025] The first groove 23 is provided with a first positioning part 24 for cable positioning, and the positioning part has a wire passing groove 25.

[0026] A first positioning groove 33 is provided on the bottom surface of the upper mold 3 corresponding to the position of the positioning member. A wire positioning portion 34 is provided in the first positioning groove 33 corresponding to the position of the wire passing groove 25. After the connector 7 is connected to the cable, a part of the connector 7 is placed at the lower mold 2, and the cable enters the wire positioning portion 34, thereby avoiding deviation during the injection molding process.

[0027] A first installation groove (not shown in the figure) for installing the mold strip 5 is provided on the top surface of the lower mold 2. A second installation groove 35 is provided on the bottom surface of the upper mold 3 corresponding to the position of the mold strip 5.

[0028] The mold strip 5 is provided with a first channel 51. The first channel 51 extends from the top surface of the mold strip 5 to the side surface. A second channel 26 is provided on the top surface of the lower mold 2 corresponding to the position of the first channel 51. The first channel 51 and the second channel 26 are communicated.

[0029] A third channel is provided at the position of the second installation groove 35 corresponding to the first channel 51. The third channel extends to the bottom surface of the upper mold 3. A fourth channel 37 is provided on the bottom surface of the upper mold 3 corresponding to the position of the third channel. The third channel and the fourth channel 37 are communicated. Among them, the first channel 51 and the third channel together form a first runner, and the second channel 26 and the fourth channel 37 together form a second runner.

[0030] A feed hole 38 is provided in the third channel. The injection molding equipment injects the molten raw material into the first runner through the feed hole 38. Then, the molten raw material flows to the second runner and flows into the molding cavity through the second runner.

[0031] The injection mold for the cable and the connector 7 includes a second positioning member 6. The second positioning member 6 includes a main body 61 and a positioning portion 62 provided on the side surface of the main body 61. The positioning portion 62 extends between the mold strip 5 and the first molding concave table. There is a gap between the bottom surface of the positioning portion 62 and the top surface of the lower mold 2, and there is a gap between the top surface of the positioning portion 62 and the bottom surface of the upper mold 3. Since the connector 7 processed by the present invention has two plug-in ends with a gap between the two plug-in ends, the positioning portion 62 can separate the two plug-in ends to ensure that the gap between the two plug-in ends meets the design requirements after the injection molding is completed. The second positioning member 6 can be designed in a detachable connection manner. After inserting the positioning portion 62 into the two plug-in ends, the second positioning member 6 is installed on the lower mold 2.

[0032] A second positioning groove 39 is provided on the upper mold 3 corresponding to the position of the main body 61 of the positioning member. The second positioning groove 39 prevents the second positioning member 6 from deviating. In addition, positioning holes and positioning pins can be provided on both the upper mold 3 and the lower mold 2 to ensure the accuracy of mold closing.

[0033] In this embodiment, there are two first formed concave portions 21. Except for the first channel 51 and the second channel 26 (i.e., only one first runner is provided as the main runner), the other corresponding structures are also provided in two. At the same time, there are also two positioning portions 62 of the second positioning member 6. After the injection molding raw material enters from the first runner, it flows to the two second runners respectively, and then flows into the two molding cavities respectively, so that the injection molding processing of the two connectors 7 can be completed simultaneously.
