Description

Technical Field

[0001] This utility model relates to the field of terminal embedding injection molding technology, and specifically to a terminal positioning fixture for terminal embedding injection molding. Background Technology

[0002] Terminal insertion injection molding technology, as a key process in modern precision manufacturing, plays an important role in the connector manufacturing field. Currently, conventional terminal positioning methods mainly fall into two categories: manual loading and automated robotic loading.

[0003] For multi-cavity products, manual feeding requires repeated placement of terminals dozens of times, resulting in low production efficiency. Moreover, the positioning accuracy of manual placement is greatly affected by the worker's skill level, and terminal position deviations can easily lead to problems such as short circuits or poor contact in the molded product. In addition, workers who come into contact with the mold are at risk of burns, posing a safety hazard. Although automated feeding systems can improve efficiency, their equipment investment costs are high, and they require supporting vision inspection systems and precision servo mechanisms. For small and medium-batch orders, the amortization cost of the equipment makes the product lose its market competitiveness. Therefore, existing technologies still have shortcomings and deficiencies. Utility Model Content

[0004] This invention provides a terminal positioning fixture for terminal embedding injection molding, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a terminal positioning fixture for terminal embedding injection molding, including a horizontally arranged positioning plate, first positioning posts fixedly connected to the four corners of the bottom surface of the positioning plate, a plurality of first guide holes opened on the positioning plate, a fixing plate provided above the positioning plate, a second guide hole opened on the fixing plate and aligned with the first guide holes, a horizontally sliding blocking plate provided between the positioning plate and the fixing plate, a third guide hole opened on the blocking plate corresponding to the first guide holes, a blocking hole opened on the blocking plate on one side of the third guide hole, and the blocking hole communicating with the third guide hole.

[0006] Preferably, sliding posts are fixedly connected to the four corners of the top surface of the positioning plate, and sliding holes corresponding to the sliding posts are opened on the blocking plate. The sliding holes are fitted onto the corresponding sliding posts and are slidably connected to the sliding posts.

[0007] Preferably, a second positioning post is fixedly connected to the sliding post, and a positioning hole corresponding to the second positioning post is provided on the fixed plate.

[0009] Preferably, a first hand-held part is fixedly connected to one side of the top surface of the fixed plate, and a second hand-held part is fixedly connected to one side of the top surface of the blocking plate.

[0010] Preferably, both the first and second hand grips have anti-slip textures on their surfaces.

[0011] The beneficial effects of this utility model are as follows: (1) Compared with manual feeding, this utility model can simultaneously position multiple terminals, realize one-time feeding of multi-cavity products, thereby improving work efficiency and terminal positioning accuracy. In addition, the positioning fixture has low manufacturing cost and simple operation, and can be applied to the production of small and medium batch products; (2) Since the terminal placement and positioning are completed outside the mold, the contact between personnel and the high temperature mold surface can be reduced, thereby reducing the risk of workers being burned.

[0014] The present invention will be further described below with reference to the accompanying drawings. The following description is based on the accompanying drawings. Figure 1 The direction in the middle is the reference.

[0015] like Figure 1-7As shown, this utility model provides a terminal positioning fixture for terminal embedding injection molding, including a horizontally arranged positioning plate 1, with first positioning posts 2 fixedly connected to the four corners of the bottom surface of the positioning plate 1, and a plurality of first guide holes 3 opened on the positioning plate 1. In this embodiment, the number of first guide holes 3 is 58, and the position of the first guide holes 3 corresponds to the position of the terminal 10. A fixing plate 4 is provided above the positioning plate 1, and a second guide hole 5 is opened on the fixing plate 4, which is aligned with the first guide hole 3. A horizontally sliding blocking plate 6 is provided between the positioning plate 1 and the fixing plate 4, and a third guide hole 7 corresponding to the first guide hole 3 is opened on the blocking plate 6. A blocking hole 8 is opened on the blocking plate 6 on one side of the third guide hole 7, and the blocking hole 8 is connected to the third guide hole 7.

[0016] Specifically, the positioning fixture is used in conjunction with the mold 9. The mold 9 has a positioning groove corresponding to the first positioning post 2. In use, the operator places the fixture on the worktable, slides the blocking plate 6 backward so that the blocking hole 8 is aligned with the first guide hole 3, and then inserts the terminals 10 one by one through the second guide hole 5 of the fixing plate 4. Figure 6 As shown, stop when the head of terminal 10 contacts the blocking hole 8. At this time, terminal 10 is directly above the first guide hole 3. Align the first positioning pin 2 with the positioning groove, and gently shake the fixture to fully position it. Then, push the blocking plate 6 forward so that the third guide hole 7 is aligned with the first guide hole 3. Figure 7 As shown, gently tap the terminal 10 so that it passes through the second guide hole 5, the third guide hole 7 and the first guide hole 3 in sequence, and is finally accurately inserted into the mold 9. Finally, after confirming that all terminals 10 are in place, start the injection molding machine to close the mold. After the injection molding is completed, remove the tooling vertically upward to complete one work cycle.

[0017] In some embodiments, sliding posts 11 are fixedly connected to the four corners of the top surface of the positioning plate 1. A sliding hole 12 corresponding to the sliding post 11 is provided on the blocking plate 6. The sliding hole 12 is sleeved on the corresponding sliding post 11 and slidably connected to it. The blocking plate 6 is slidably connected to the positioning plate 1 through the sliding hole 12 and the sliding post 11. In use, the sliding hole 12 can limit the blocking plate 6, restricting its sliding stroke. When the blocking plate 6 is slid backward to the limit position, the blocking hole 8 aligns with the first guide hole 3. When the blocking plate 6 is slid forward to the limit position, the third guide hole 7 aligns with the first guide hole 3, thereby facilitating worker operation.

[0018] In some embodiments, a second positioning post 13 is fixedly connected to the sliding post 11, and a positioning hole 14 corresponding to the second positioning post 13 is provided on the fixing plate 4. The fixing plate 4 can be positioned by the second positioning post 13 and the positioning hole 14, thereby ensuring that the second guide hole 5 is aligned with the first guide hole 3.

[0019] In some embodiments, the lower end of the first positioning post 2 is provided with a tapered guide portion 15, which facilitates the insertion of the first positioning post 2 into the positioning groove.

[0020] In some embodiments, a first hand-held part 16 is fixedly connected to one side of the top surface of the fixed plate 4, which facilitates the worker to pick up the fixed plate 4. A second hand-held part 17 is fixedly connected to one side of the top surface of the blocking plate 6, which facilitates the worker to slide the blocking plate 6.

[0021] In some embodiments, the surfaces of the first hand grip 16 and the second hand grip 17 are provided with anti-slip textures 18. By providing anti-slip textures 18, the friction can be increased, reducing the risk of the tooling falling off when the worker uses it.

[0022] The above embodiments can be combined with each other.

[0023] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
