Description

Technical Field

[0001] This application relates to the field of connector manufacturing technology, and in particular to a terminal embedding and forming apparatus. Background Technology

[0002] Terminals are primarily used in connector applications such as automotive and communications. In related technologies, terminal embedding molding devices require extremely high positioning accuracy during the molding process. However, existing devices have relatively simple positioning mechanisms, which cannot accurately place the terminals in the predetermined positions, resulting in significant positional deviations after molding. Furthermore, existing devices typically have only one molding area, and the cavity arrangement is relatively simple, failing to meet the needs of large-scale production.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] In view of at least one of the above technical problems, this application provides a terminal embedding molding apparatus, which solves the problem that the positioning mechanism of the existing apparatus is relatively simple in design and cannot accurately place the terminal in the predetermined position, resulting in a large deviation in the position of the molded terminal.

[0005] This application provides a terminal embedding molding apparatus, comprising:

[0006] The mold core has two forming areas, and multiple cavities are spaced apart along a second direction in one forming area.

[0007] The positioning mechanism includes a first movable plate, a first ejector rod, a strip moving seat, and positioning pins. Multiple positioning pins are arranged at intervals along a second direction on one side of the forming area. Multiple strip moving seats are movably disposed on one side of the forming area. The strip moving seats are provided with a transfer groove along the second direction. The strip moving seats are provided with positioning holes along a third direction that cooperate with the positioning pins. The positioning holes are connected to the transfer groove. The first movable plate is movably disposed on one side of the mold core. Multiple first ejector rods are fixed between the first movable plate and the strip moving seat.

[0008] One of the above technical solutions has at least one of the following advantages or beneficial effects: This device uses a positioning pin to cooperate with the positioning hole on the material strip moving block to accurately position the material strip, ensuring that the terminals on the material strip can be aligned with the cavity on the molding area, thereby avoiding deviation in the embedded position of the terminals and improving the product yield.

[0009] In some possible implementations, a pair of limiting mechanisms are set on the molding area, with the two limiting mechanisms located on both sides of the cavity.

[0010] In some possible implementations, the limiting mechanism includes a first limiting block, a second limiting block, and a third limiting block. The first limiting block, the second limiting block, and the third limiting block are arranged sequentially along the second direction. The first limiting block and the third limiting block are located on both sides of the second limiting block, and the second limiting block is spaced apart from the first limiting block and the third limiting block, respectively.

[0011] In some possible implementations, receiving grooves communicating with the cavity are arranged side by side on the molding area. The receiving grooves extend along a first direction, with one receiving groove located between the first limiting block and the second limiting block, and the other receiving groove located between the second limiting block and the third limiting block.

[0012] In some possible implementations, the forming area is provided with an insert groove that mates with the material strip moving seat.

[0013] In some possible implementations, a guide hole is provided on the bottom wall of the embedding groove, and a guide post that cooperates with the guide hole is provided on the material strip moving seat.

[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] like Figures 1 to 4 As shown, this embodiment provides a terminal embedding molding device, including: a mold core 100 and a positioning mechanism 200. The mold core 100 has two molding areas 110, and a plurality of cavities 120 are spaced apart along a second direction in one molding area 110; the positioning mechanism 200 includes a first moving plate 210, a first ejector rod 220, a strip moving seat 230 and positioning pins 240. There are multiple positioning pins 240 and they are spaced apart along the second direction on one side of the molding area 110. There are multiple strip moving seats 230 and they are movably disposed on one side of the molding area 110. The strip moving seat 230 is provided with a transfer groove 231 along the second direction. The strip moving seat 230 is provided with a positioning hole 232 along a third direction that cooperates with the positioning pins 240. The positioning hole 232 communicates with the transfer groove 231. The first moving plate 210 is movably disposed on one side of the mold core 100. There are multiple first ejector rods 220 and they are fixed between the first moving plate 210 and the strip moving seat 230.

[0026] It is understandable that the first direction corresponds to the X-axis (left-right direction) of the spatial coordinate system, the second direction corresponds to the Y-axis (front-back direction) of the spatial coordinate system, and the third direction corresponds to the Z-axis (up-down direction) of the spatial coordinate system. The first, second, and third directions are all perpendicular to each other.

[0027] The first movable plate 210 is movably disposed on one side of the mold core 100. For example, the first movable plate 210 is driven to be connected to a drive source so that the drive source drives the first movable plate 210 to reciprocate along a third direction. In this way, the first ejector rod 220 moves accordingly, thereby driving the material strip moving seat 230 to reciprocate along a third direction.

[0028] There are multiple strip moving seats 230. For example, there are three strip moving seats 230, of which two strip moving seats 230 are located on one side of the forming area 110, and one strip moving seat 230 is located between the two forming areas 110. When the first moving plate 210 moves, the three strip moving seats 230 move synchronously in the third direction.

[0029] The strip moving seat 230 is provided with a positioning hole 232 along a third direction, which mates with the positioning pin 240. The positioning hole 232 communicates with the transfer groove 231. Thus, when the strip is located in the transfer groove 231 of the strip moving seat 230, and the strip moving seat 230 moves toward the mold core 100, the positioning pin 240 passes through the hole in the strip in the transfer groove 231 and the positioning hole 232, thereby achieving strip positioning.

[0030] Before molding, the strip moving seat 230 disengages from the mold core 100, and the strip moves in the transfer groove 231. Driven, the strip moving seat 230 moves toward the mold core 100, and the positioning pin 240 passes through the hole in the strip in the transfer groove 231 and the positioning hole 232 until the strip moving seat 230 is fitted into the mold core 100.

[0031] In this embodiment, the terminal embedding molding device uses a positioning pin 240 to cooperate with a positioning hole 232 on the material strip moving block to accurately position the material strip, ensuring that the terminals on the material strip can be aligned with the cavity 120 on the molding area 110, thereby avoiding terminal embedding position deviation and improving product yield.

[0032] like Figures 1 to 4 As shown, in some embodiments, a pair of limiting mechanisms 130 are provided on the molding area 110, with the two limiting mechanisms 130 located on both sides of the cavity 120. The limiting mechanisms 130 can position the connecting strip of the material strip, thereby restricting the degree of freedom of the material strip in the second direction.

[0033] like Figures 1 to 4 As shown, in some embodiments, the limiting mechanism 130 includes a first limiting block 131, a second limiting block 132, and a third limiting block 133. The first limiting block 131, the second limiting block 132, and the third limiting block 133 are arranged sequentially along the second direction. The first limiting block 131 and the third limiting block 133 are located on both sides of the second limiting block 132, and the second limiting block 132 is spaced apart from the first limiting block 131 and the third limiting block 133, respectively.

[0034] The first limiting block 131, the second limiting block 132, and the third limiting block 133 are arranged sequentially along the second direction. For example, the first limiting block 131, the second limiting block 132, and the third limiting block 133 are integrally formed with the mold core 100. The upper edges of the first limiting block 131, the second limiting block 132, and the third limiting block 133 are all provided with a chamfered structure, which facilitates the entry of the connecting belt of the material strip.

[0035] like Figures 1 to 4 As shown, in some embodiments, the molding area 110 is provided with parallel receiving grooves 140 communicating with the cavity 120. The receiving grooves 140 extend along a first direction, with one receiving groove 140 located between the first limiting block 131 and the second limiting block 132, and the other receiving groove 140 located between the second limiting block 132 and the third limiting block 133. Thus, the receiving grooves 140 are used to receive the connecting strip of the material strip.

[0036] like Figures 1 to 4 As shown, in some embodiments, the forming area 110 is provided with an insert groove 150 that mates with the strip moving seat 230. Thus, during forming, the strip moving seat 230 is fitted into the insert groove 150.

[0037] like Figures 1 to 4 As shown, in some embodiments, a guide hole is provided on the bottom wall of the embedding groove 150, and a guide post is provided on the material strip moving seat 230 to cooperate with the guide hole. In this way, the guide installation between the material strip moving seat 230 and the embedding groove 150 is realized by cooperating with the guide post on the material strip moving seat 230 through the wire hole of the embedding groove 150.
