Description

Technical Field

[0001] The utility model belongs to the technical field of injection molded parts, and particularly relates to a structure for preventing displacement of contact pins of injection molded parts. Background Technique

[0002] A structure for preventing displacement of contact pins of injection molded parts is a structure designed specifically to solve the problem that contact pins of injection molded parts with contact pins are prone to displacement under the influence of injection pressure during the production process. It is usually composed of specific fixing components, which may include card slots, positioning posts, clamping devices, etc. These components can firmly fix the contact pins during the injection process, so that they can also maintain an accurate position under the action of injection pressure, ensuring the quality and performance of the injection molded parts. This structure is widely used in the production of injection molded parts with contact pins in fields such as electronics and electrical appliances, providing a strong guarantee for improving the yield rate and reliability of products.

[0003] There is a relatively prominent problem in the actual production process of existing injection molded parts with contact pins. During the injection process, when the injection pressure is applied to the injection molded parts, the contact pins are extremely prone to displacement under the action of this strong pressure. Since the contact pins usually need to be accurately positioned at specific positions of the injection molded parts to ensure the normal realization of subsequent electrical connections or other functions, this easy displacement characteristic under injection pressure brings great uncertainty and quality risks to production. Summary of the Utility Model

By setting a stop mechanism, it solves the problem that during the injection process, when the injection pressure is applied to the injection molded parts, the contact pins are extremely prone to displacement under the action of this strong pressure. Since the contact pins usually need to be accurately positioned at specific positions of the injection molded parts to ensure the normal realization of subsequent electrical connections or other functions, this easy displacement characteristic under injection pressure brings great uncertainty and quality risks to production.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a structure for preventing displacement of contact pins of injection molded parts, including a rectangular frame, and a plurality of stop mechanisms and configuration mechanisms arranged on the rectangular frame;

The outer wall of the contact pin 25 is in contact with the plurality of balls 23. An injection molding housing 26 is fixedly sleeved on the outer wall of the contact pin 25.

[0030] The configuration mechanism 3 includes a plurality of fixing components and adjustment components. The fixing components include fixed fixtures 31 fixedly connected to the inner wall of the rectangular frame 1. A movable fixture 32 is slidably connected to the inner wall of the rectangular frame 1. The inner walls of the fixed fixture 31 and the movable fixture 32 are in contact with the injection molding housing 26.

[0031] By pressing the pressing member 34 inward, the pressing member 34 cooperates with the first slide bar 33 to compress the first spring 36 thereon, thereby driving the movable fixture 32 to separate from the fixed fixture 31 by means of the connecting rod 35.

[0032] Two sliding rods 33 are slidably connected to the inner wall of the rectangular frame 1. The left ends of the two sliding rods 33 are fixedly connected to a pressing member 34. Two connecting rods 35 are rotatably connected to the bottom inner wall of the rectangular frame 1. One ends of the two connecting rods 35 are rotatably connected to the movable fixture 32, and the other ends of the two connecting rods 35 are rotatably connected to the pressing member 34.

[0033] By pressing the pressing member 34 to cooperate with the first sliding rod 33 to compress the first spring 36 thereon, the connecting rod 35 can drive the movable fixture 32 to separate from the fixed fixture 31.

[0034] Two first springs 36 are fixedly connected to the right end of the pressing member 34. The other ends of the two first springs 36 are fixedly connected to the inner wall of the rectangular frame 1. A second spring 37 is fixedly connected to the left end of the movable fixture 32. The other end of the second spring 37 is fixedly connected to the pressing member 34.

[0035] By releasing the pressing member 34, at this time, the movable fixture 32 will approach the fixed fixture 31 under the cooperation of the two first springs 36, the second spring 37 and the two connecting rods 35, so as to clamp the injection molded housing 26.

[0036] A fixed frame 38 is arranged on the back of the rectangular frame 1. A first chute 39 and a second chute 391 are opened on the front of the fixed frame 38. Two second sliding rods 392 are fixedly connected to the back of the rectangular frame 1. The rear ends of the two second sliding rods 392 both extend outside the first chute 39 and the second chute 391 and are slidably connected to the first chute 39 and the second chute 391.

[0037] Through the cooperation of the first chute 39 and the second chute 391 with the two second sliding rods 392, the rectangular frame 1 can move left and right stably.

A plurality of adjusting chutes 395 are opened on the front of the rectangular plate 394. The rear ends of the second sliding rods 392 extend into the adjusting chutes 395 and are slidably connected to the adjusting chutes 395.

[0039] When the rectangular plate 394 moves upward, the plurality of adjusting chutes 395 on the rectangular plate 394 will drive the second sliding rods 392 on the rectangular frame 1 to slide synchronously. Due to the special design of the adjusting chutes 395, a plurality of injection molded parts can be adjusted inward at equal intervals to meet different production requirements and layout requirements.

[0040] The adjustment component includes a U-shaped frame 396 fixedly connected to the right side of the fixed frame 38. A motor 397 is fixedly connected to the top of the U-shaped frame 396. The output shaft of the motor 397 is fixedly connected to a first threaded rod 398 through a coupling. The first threaded rod 398 penetrates through the U-shaped frame 396 and is rotatably connected to the U-shaped frame 396. A slider 399 is sleeved on the outer wall of the first threaded rod 398 in a threaded manner. The left end of the slider 399 is fixedly connected to a rectangular plate 394.

[0041] By starting the motor 397, the motor 397 will drive the first threaded rod 398 to rotate. At the same time, when the first threaded rod 398 rotates, it will drive the slider 399 thereon to cooperate with the two third chutes 393, so that the rectangular plate 394 can move upward.

[0042] A specific application of this embodiment is as follows: When in use, first, the pressing member 34 can be pressed inward. At this time, the pressing member 34 will cooperate with the first slide rod 33 to compress the first spring 36 thereon. Through such an operation, the connecting rod 35 can be used to drive the movable fixture 32 to separate from the fixed fixture 31, so that the injection molding shell 26 can be smoothly placed between the fixed fixture 31 and the movable fixture 32. After placing, release the pressing member 34. At this time, the movable fixture 32 will approach the fixed fixture 31 under the cooperation of the two first springs 36, the second spring 37 and the two connecting rods 35 to clamp the injection molding shell 26. Through this setting, the cumbersome processes of installation and disassembly can be effectively reduced, thereby improving the installation efficiency; immediately afterwards, the contact pin 25 is inserted into the injection molding shell 26. At the same time, the contact pin 25 will be limited by a number of positioning mold strips 24 and balls 23, which can prevent the injection pressure from causing the contact pin 25 to displace during injection molding and ensure the position stability of the contact pin during the injection molding process; when it is necessary to adjust the spacing between multiple injection molded parts, the motor 397 can be started. The motor 397 will drive the first threaded rod 398 to rotate. At the same time, when the first threaded rod 398 rotates, it will drive the slider 399 thereon to cooperate with the two third chutes 393, so that the rectangular plate 394 can move upward. Moreover, during the upward movement of the rectangular plate 394, the multiple adjustment chutes 395 on the rectangular plate 394 will drive the second slide rod 392 on the rectangular frame 1 to slide synchronously. Due to the special design of the adjustment chutes 395, multiple injection molded parts can be adjusted inward at equal intervals to meet different production requirements and layout requirements.
