Technical Field

[0001] This utility model relates to the field of molding technology, and more specifically, to a molding mold for insulating housings of PCB connectors. Background Technology

[0002] The molding die for the insulating housing of printed circuit board connectors is a key tool used in the manufacture of PCB connector insulating housings. It plays a vital role in the field of electronic equipment manufacturing. Its main purpose is to ensure the accuracy and consistency of the insulating housing, and secondly, to provide high-precision molding. The molding die adopts a precision design and manufacturing process, which can ensure that the dimensional accuracy, shape accuracy and positional accuracy of the insulating housing meet strict standards.

[0003] Among the existing publicly available documents, patent publication number CN221109628U discloses a hat-shaped shell forming mold. This technology uses multiple gas springs to elastically support the material support plate, greatly reducing the cost of the support plate assembly. It also has a simpler structure, lower maintenance costs, and solves the problem of wrinkles appearing at the workpiece edges during the forming process, thus improving the yield rate. Furthermore, this solution is also applicable to some presses without a bottom cylinder or with insufficient bottom cylinder pressure. However, this technology still has the following drawbacks.

[0004] During the molding process of the insulating shell of the PCB connector, a molding mold is required to perform the molding operation. During the injection molding, the injection liquid will drip and leak down the injection hole. Once this problem occurs, it will cause workstation contamination and make it difficult to collect the overflowing injection liquid, resulting in poor collection effect. Utility Model Content

A socket block is slidably connected to the outer wall of the guide post, and a limiting block is fixedly connected to the outer wall of the socket block.

[0006] Preferably, a gap is provided between both injection tubes and the collection box, and the inner wall of the collection box is a smooth surface. The outer wall of the slider and the inner wall of the sliding frame are both smooth surfaces, and the vertical cross-sectional shape of the slider is T-shaped. A support block is fixedly connected to one end of the guide post, away from the limiting block, and the support block is used to limit and support the sleeve block. A handle is fixedly connected to one side of the collection box, and the handle has a concave cross-sectional shape. A base plate is fixedly installed on the lower surface of the lower molding die, and the base plate is used to support the lower molding die. Baffles are fixedly connected to the upper surface of the collection box near both ends.

[0007] In use, this technology uses a support block to limit the movement of the connecting block. The connecting block moves to the left along the outer wall of the guide post, and the limiting block limits one end of the slider. The hand holds the handle, and the collection box slides along the upper surface of the slide frame. The slider slides and is limited to the inner wall of the slide frame. The slide frame supports the slider, and the slider is limited to the collection box. The injection liquid overflowing from the injection tube flows down into the collection box and is collected inside.

[0008] Preferably, a positioning counterweight assembly is provided above the lower forming mold; the positioning counterweight assembly includes multiple guide rods fixedly arranged above the lower forming mold, an upper mold is provided above the guide rods, a pressure block is fixedly connected to the upper surface of the upper mold, a fixing plate is fixedly installed on the upper surface of the pressure block, and a threaded hole is opened inside the fixing plate; guide holes are opened on the inner wall of the pressure block and near its four corners.

[0009] In use, this technology uses a fixed plate with a counterweight block. The counterweight block moves the upper mold downward, and the guide hole on the counterweight block aligns with the outer wall of the guide rod to achieve positioning.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This utility model uses a collection and limiting component to limit the movement of the connecting block by a support block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-5 The diagram shows a PCB connector insulating shell molding mold. The PCB connector insulating shell molding mold is provided with a collection limiting component. The collection limiting component is set so that the injection liquid overflowing from the injection tube 3 can flow down into the collection box 2 and enter the collection box 2 for collection. It can collect the overflowing injection liquid and achieve better collection effect. The specific structure of the collection limiting component is as follows.

[0021] In this embodiment, as shown in the appendix Figure 1-4As shown, the collection box 2 is slidably located on one side of the lower molding mold 1. Two injection tubes 3 are positioned above the collection box 2, both of which are fixedly connected to the lower molding mold 1. A collection limiting assembly is provided on the lower surface of the collection box 2. This assembly includes a slider 4 fixedly mounted on the lower surface of the collection box 2, with a sliding frame 5 slidably connected to the outer wall of the slider 4. The sliding frame 5 is fixedly connected to the lower molding mold 1 and slidably connected to the collection box 2. A guide post 6 is fixedly installed on one side of the sliding frame 5. A sleeve block 7 is slidably connected to the outer wall of the guide post 6, and a limiting block 8 is fixedly connected to the outer wall of the sleeve block 7. A gap exists between both injection tubes 3 and the collection box 2. The inner wall of the collection box 2 is a smooth surface. The outer wall of the slider 4 and the inner wall of the sliding frame 5 are both smooth surfaces, and the vertical cross-section of the slider 4 is T-shaped.

[0022] In this embodiment, as shown in the appendix Figure 1-4 As shown, a support block 9 is fixedly connected to one end of the guide post 6 and at a position away from the limiting block 8. The support block 9 is used to limit and support the sleeve block 7, so that the sleeve block 7 can be limited by the support block 9. The limiting and supporting support block 9 has a better effect. A handle 14 is fixedly connected to one side of the collection box 2. The cross-sectional shape of the handle 14 is concave, so that the hand can hold the handle 14 and push the handle 14 to push the collection box 2 to move, so that the collection box 2 can be moved. A base plate 17 is fixedly installed on the lower surface of the lower forming mold 1. The base plate 17 is used to support the lower forming mold 1. A baffle 18 is fixedly connected to the upper surface of the collection box 2 and near its two ends, so that the base plate 17 can support the lower surface of the lower forming mold 1. The two baffles 18 limit the collection inside the collection box 2 to continue collecting.

[0023] When using the PCB connector insulating shell molding mold, the threaded hole 16 is installed on the stamping equipment. The fixed plate 13 counterweights the pressure block 12, which in turn counterweights the upper mold 11.

The positioning is achieved by injecting the injection liquid into the lower molding mold 1 through the injection tube 3.

[0024] The support block 9 limits the movement of the connecting block 7. When the connecting block 7 moves to the left, it moves along the outer wall of the guide post 6 to the left. The connecting block 7 drives the limiting block 8 to move to the left. The limiting block 8 limits one end of the slider 4. At the same time, the limiting block 8 makes contact with the end of the slide frame 5. The hand holds the handle 14 and pushes the handle 14. The handle 14 pushes the collection box 2 to move. The collection box 2 slides along the upper surface of the slide frame 5. The slider 4 slides and is limited to the inner wall of the slide frame 5. At the same time, the lower molding mold 1 supports the slide frame 5, the slide frame 5 supports the slider 4, and the slider 4 is limited to the collection box 2. In this way, the injection liquid overflowing from the injection tube 3 flows down into the collection box 2 and enters the collection box 2 for collection. At the same time, the two baffles 18 limit the collection inside the collection box 2 to continue collection.

[0025] In this embodiment, as shown in the appendix Figure 1-5 As shown, a positioning counterweight assembly is provided above the lower forming mold 1; the positioning counterweight assembly includes multiple guide rods 10 fixedly arranged above the lower forming mold 1, an upper mold 11 is provided above the guide rods 10, a pressure block 12 is fixedly connected to the upper surface of the upper mold 11, a fixing plate 13 is fixedly installed on the upper surface of the pressure block 12, and a threaded hole 16 is opened inside the fixing plate 13; guide holes 15 are opened on the inner wall of the pressure block 12 and near its four corners.
