Description

Technical Field

[0001] This utility model relates to the field of insert injection molding implantation, specifically to a multi-pin needle handling and implantation tooling. Background Technology

[0002] In the field of electronic device manufacturing, the reliability and accuracy of connectors directly affect product performance, especially with the increasing demand for multi-pin products. The implantation of these internal pins requires extremely high-precision mold design and efficient injection molding processes. However, current factories commonly use manual single-pin implantation, which is inefficient and struggles to ensure consistent placement, increasing product scrap rates and failing to meet the demands of mass production. Therefore, there is an urgent need to develop a multi-pin handling and implantation fixture. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of low efficiency and inconsistent implantation positions in the existing technology, and to provide a multi-pin needle transport and implantation tool that can improve the efficiency and accuracy of multi-pin product implantation.

[0004] To achieve the above objectives, this utility model provides a multi-pin needle transport and implantation fixture, comprising: The base plate has multiple positioning holes; The carrier has a limiting hole that penetrates through the carrier. The carrier includes a fixing part and a clamping part. The fixing part is disposed in the positioning hole. An elastic ring is fitted at the bottom of the clamping part to clamp the pin; An ejector pin is correspondingly positioned below the limiting hole to eject the pin from the limiting hole; A stripper plate is placed at the bottom of the ejector pin and parallel to the base plate to push the ejector pin, thereby ejecting the pin out of the limiting hole.

[0005] Optionally, the clamping portion includes a tightening portion connected to the fixing portion, and at least two clamping arms extending upward from the tightening portion.

[0006] Optionally, the outer wall diameter of the tightening part is equal to the outer wall diameter of the lower base of the clamping arm, and both are larger than the outer wall diameter of the upper arm body of the clamping arm, so that the clamping arm has a variable diameter structure.

[0007] Optionally, the tightening part has a circumferential groove for partially accommodating the tightening ring.

[0008] Optionally, a spring assembly is provided between the base plate and the stripper plate to provide elastic force for the reset of the stripper plate and the ejector pin.

[0009] Optionally, a handle is provided on the base plate for handling the tooling and for assisting in pressing down the stripping plate during implantation.

[0010] Optionally, a limit guide post is provided on the upper side of the base plate.

[0011] Optionally, at least four support legs are provided on the underside of the base plate, with a height greater than the maximum interval between the base plate and the stripper plate.

[0012] Through the above technical solution, this utility model provides a multi-pin needle handling and implantation fixture. This fixture adapts to the ejection requirements of multiple pin needles by setting ejector pins, and on this basis, a stripper plate is set to uniformly realize the ejection action of multiple ejector pins. It replaces the inefficient implantation method of relying on manual implantation of molds in the prior art, and improves the efficiency and accuracy of multi-pin needle implantation.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0017] Figure 1 This is a top view of a multi-pin needle transport and implantation fixture according to one embodiment of the present invention. Figure 2 This is a schematic diagram of a multi-pin needle transport and implantation fixture according to one embodiment of the present invention. Figure 3 This is a schematic diagram of a carrier for a multi-pin needle transport and implantation fixture according to one embodiment of this utility model. Figures 1 to 3 The multi-pin needle handling and implantation fixture includes a base plate 01, a carrier 02, a tensioning ring 03, an ejector needle 08, and a stripping plate 04. The carrier 02 also includes a fixing part 22 and a clamping part 23.

[0018] Specifically, the base plate 01 has multiple positioning holes 11. The specific arrangement of these positioning holes 11 on the base plate 01 can be any of the forms known to those skilled in the art, provided it meets the requirements for pin insertion, including but not limited to even distribution and centrally symmetrical distribution. In one example of this invention, considering the overall force balance during ejection, such as... Figure 1 As shown, the positioning holes 11 can be symmetrically arranged near the two side edges of the base plate 01. This arrangement provides space in the middle of the base plate 01 to facilitate the installation of handles and other components. Furthermore, since the positioning holes 11 are located near the two side edges, the ejector plate 04 can smoothly achieve synchronous ejection from both sides by applying a pushing force in the middle during implantation.

[0019] The carrier 02 is set in the positioning hole 11, such as Figure 2 and Figure 3 As shown, the carrier 02 has a limiting hole 21 extending axially through the carrier 02. This limiting hole 21 is used to provide an insertion channel and axial positioning for the pin. The carrier 02 includes a fixing part 22 and a clamping part 23. The shape of the fixing part 22 matches the preset positioning hole 11 on the base plate 01. The fixing part 22 is disposed in the positioning hole 11, limiting the degree of freedom of the carrier 02 in the horizontal direction, so that the carrier 02 can be stably fixed on the base plate 01.

[0020] To achieve effective pin capture, such as Figure 3As shown, the clamping portion 23 includes a tightening portion 232 connected to the fixing portion 22, and at least two clamping arms 231 extending upward from the tightening portion 232. Specifically, the clamping arms 231 are formed by creating a groove extending downward from the top on the clamping portion 23, thereby forming a clamping space that allows for elastic deformation. The number of clamping arms 231 can be set according to the specific clamping requirements of different pins. In one embodiment of this invention, to reduce processing losses, it is preferable that there are two clamping arms 231. Furthermore, the inner sidewall of the clamping arms 231 is machined with anti-slip grooves to provide sufficient friction when clamping the pin, so that the pin is better fixed in the clamping portion 23.

[0021] The tension ring 03 is sleeved on the outer wall of the clamping part 23 to provide clamping force to the clamping part 23 to clamp the pin. For example... Figure 3 As shown, the outer wall of the tightening part 232 has an annular groove (i.e., a circumferential groove) for partially accommodating the tightening ring 03. During operation, the tightening ring 03 is partially accommodated within this groove, preventing accidental axial displacement. The tightening ring 03 radially compresses the clamping arm 231 with its elasticity, causing the size of the limiting hole 21 to shrink, thereby clamping and fixing the pin therein. In one embodiment of this invention, the material of the tightening ring 03 is preferably a rubber ring. This unique clamping design allows a set of tooling to adapt to the implantation needs of pins of different sizes by replacing different specifications of the tightening ring 03, exhibiting strong versatility.

[0022] Preferably, such as Figure 3 As shown, the outer diameter of the tightening part 232 is equal to the outer diameter of the lower end of the clamping arm 231, and both are larger than the outer diameter of the upper end of the clamping arm 231, making the clamping part 231 have a stepped variable diameter structure. When the tightening part 232 is subjected to the axial pressure of the tightening ring 03, it tightens inward. The lower end of the clamping arm 231 contracts with the tightening part 232 and drives its upper end to move inward, thereby changing the size of the limiting hole 21 to adjust the clamping force on the pin. This variable diameter structure design ensures that the main tightening force acts on the lower base with a larger cross-sectional area, effectively preventing the smaller upper arm from breaking due to directly bearing excessive tightening force.

[0023] Ejector pin 08 is slidably disposed within and below the limiting hole 21, for ejecting the pin from the limiting hole 21. Specifically, the diameter of ejector pin 08 matches the limiting hole 21, allowing ejector pin 08 to move up and down within the limiting hole 21. Stripper plate 04 is disposed below and parallel to base plate 01, and abuts against the bottom of ejector pin 08. When stripper plate 04 is pressed, it pushes ejector pin 08 upward along the limiting hole 21, thereby ejecting the pin, detaching it from carrier 02, and inserting it into the injection mold. The parallel arrangement of stripper plate 04 ensures that all ejector pins 08 do not shift during ejection, preventing misalignment of the pin insertion.

[0024] To achieve automatic reset and reduce rigid collisions, a spring assembly 06 is connected between the base plate 01 and the stripper plate 04. The spring assembly 06 provides elastic restoring force for the reset of the stripper plate 04 and the ejector pin 08. After the stripping operation, the spring assembly 06 undergoes elastic deformation; after the external force is removed, the restoring force of the spring assembly 06 drives the stripper plate 04 and the ejector pin 08 to automatically reset. Simultaneously, the spring assembly 06 also limits the degree of freedom of the stripper plate 04, ensuring that the stripper plate 04 remains parallel to the base plate 01 during operation, thereby preventing jamming during the ejection process.

[0025] Furthermore, a handle 05 is fixedly installed on the upper surface of the base plate 01 for handling the tooling and assisting in pressing down the stripper plate 04 during insertion. A limiting guide post 07 is also provided on the upper surface of the base plate 01 to limit the displacement or stroke of the tooling during the insertion of the pin into the injection mold, thereby achieving precise positioning.

[0026] In addition, at least four legs are provided on the lower surface of the base plate 01, and the height of the legs is greater than the maximum distance between the base plate 01 and the stripper plate 04. The bottom of the legs together form a support plane, ensuring the stability of the entire fixture when placed on the work platform in the non-working state and preventing the stripper plate 04 from being accidentally touched.

[0027] Through the above technical solution, this fixture can achieve precise and efficient implantation of multiple pins. During operation, firstly, according to the mold requirements, the carrier 02 is installed in the corresponding positioning hole 11 of the base plate 01. Then, the pin is placed into the limiting hole 21 of the carrier, and clamped by the elastic compression of the tension ring 03 fitted on the tensioning part. Next, the entire fixture is moved to the vicinity of the mold using the handle 05, and precisely positioned using the limiting guide post 07. Then, the stripper plate 04 is pressed down, compressing the spring assembly 06. The stripper plate 04 then pushes the ejector pin 08 upward, precisely ejecting the pin and implanting it into the mold cavity. Finally, the external force is removed, and the restoring force of the spring assembly 06 drives the stripper plate and ejector pin to automatically reset, completing one implantation operation.

[0028] Through the above technical solution, this utility model provides a multi-pin needle handling and implantation fixture. This fixture adapts to the ejection requirements of multiple pins by setting ejector pins, and further enhances this by setting a stripper plate to uniformly achieve the ejection action of multiple ejector pins. This replaces the inefficient implantation method in the prior art that relies on manual implantation of the mold, improving the efficiency and accuracy of multi-pin needle implantation. The preferred embodiments of this utility model have been described in detail above with reference to the accompanying drawings; however, this utility model is not limited thereto. Within the scope of the technical concept of this utility model, various simple modifications can be made to the technical solution of this utility model, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed by this utility model and are all within the protection scope of this utility model.
