Description

Technical Field

[0001] This utility model relates to the field of injection molds, and in particular to an injection molding device for connectors. Background Technology

[0002] A connector injection mold is a mold specifically designed for producing connector components. It is a key piece of equipment in connector component manufacturing, enabling the efficient and precise production of connectors used in the electronics, electrical, and communications industries. Connectors are commonly used in these industries and are essential components for connecting circuits, equipment, or systems. Through injection molding, the connector's housing, plug, and socket can be manufactured efficiently and precisely.

[0003] Traditional injection molding machines rely excessively on manual operation, reducing the level of automation. This not only affects production efficiency but also makes the production process susceptible to the influence of manual operation. For example, uneven forces may be applied, causing damage or deformation to the connector surface, affecting the appearance and function of the product. It also reduces the efficiency of the overall production line, affecting the production rhythm and output. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: This example provides an injection molding device for connectors. See [link to example]. Figures 1-4 Specifically, the assembly includes a base plate 1, a connecting plate 4, and an injection molding assembly. The base plate 1 is provided with guide posts 2, and multiple sets of guide posts 2 are distributed around the top perimeter of the base plate 1. A limiting block 6 is provided at the top of each guide post 2 to limit the movement of the connecting plate 4. The connecting plate 4 is vertically slidably mounted on the guide posts 2 and has a material discharge groove 5. First cylinders 3 are provided on both sides of the base plate 1, and the connecting plate 4 is connected to the telescopic ends of the first cylinders 3. The injection molding assembly is mounted on the base plate 1 and the connecting plate 4. The injection molding assembly includes an injection mechanism for forming the connector and an ejection mechanism for ejecting the formed connector. The ejection mechanism includes a first ejector plate 13, which is slidably mounted on the injection mechanism.

[0025] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the injection molding mechanism includes a lower molding die 7 and an upper molding die 8; the lower molding die 7 is disposed on the placement base plate 1; the upper molding die 8 is disposed on the connecting plate 4 and is in contact with the lower molding die 7; the material discharge groove 5 is provided with a pouring port 9 for liquid to flow into the lower molding die 7 and the upper molding die 8.

[0026] In the specific implementation process, such as Figure 4 As shown, the ejection mechanism further includes a second cylinder 10, a transmission plate 11, and a second ejector plate 14; the second cylinder 10 is disposed in the lower forming mold 7, and the lower forming mold 7 is provided with a cavity to accommodate the second cylinder 10; the second ejector plate 14 is connected to the top end of the telescopic end of the second cylinder 10 and is fitted into the lower forming mold 7; a plurality of transmission plates 11 are disposed in the middle of the telescopic end of the second cylinder 10, and a mounting block 12 is provided on the transmission plate 11; the first ejector plate 13 is connected to the mounting block 12 and is fitted into the lower forming mold 7;

[0027] After the connector is formed, the first cylinder 3 is activated to move the connecting plate 4 and the upper forming mold 8 upward. Then, the second cylinder 10 is activated to move the transmission plate 11, the mounting block 12, the first top plate 13 and the second top plate 14 upward. This pushes the formed connector frame until the connector is pushed out to a certain height, so that the connector is separated from the lower forming mold 7.
