Description

Technical Field

[0001] This utility model relates to the field of inductor technology, and in particular to an integrally molded inductor base mold. Background Technology

[0002] An inductor base is a component of an inductor, which is a commonly used element in electrical equipment with a wide range of applications. The manufacturing process of inductors requires the use of processing molds. With the continuous development of technology, the functions of existing inductor base molds are becoming increasingly comprehensive. Chinese utility model patent, authorized announcement number "CN212010710U", discloses an integrated inductor base mold. During use, the inductor base is formed by a storage plate. After forming, a telescopic cylinder drives a movable plate upwards. At this time, the movable plate can move a sealing plate, and then the vent plate is no longer subject to the sealing force. Symmetrically arranged exhaust fans work to cool the inductor base.

[0003] In the above technical solution, although the exhaust fan can generate a certain amount of airflow, the sealed structure inside the mold makes it difficult for the airflow to contact the mold after molding. The exhaust fan mainly promotes airflow by creating negative pressure to achieve ventilation. This ventilation method is not very effective in cooling the local high temperature area of ​​the mold. Moreover, the cooling effect of the exhaust fan depends to a large extent on the external environmental conditions, which means that relying solely on the exhaust fan may not be able to quickly and effectively dissipate the heat, thus reducing the cooling effect on the inductor base. Therefore, we propose an integrated inductor base mold. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution: an integrally molded inductor base mold, comprising:

[0028] Mold base 1, with a storage slot 10 at the bottom;

[0029] Mold cooling structure, the mold cooling structure is located on mold base 1;

[0030] The mold cooling structure includes a drain pipe 6, an inlet pipe 15, and two connecting flanges 7. The top of the mold base 1 has multiple mold cavities 8. The interior of the mold base 1 has a cooling cavity 16. The drain pipe 6 is fixedly connected to one side of the mold base 1, and the inlet pipe 15 is fixedly connected to the side of the mold base 1 away from the drain pipe 6. Both the drain pipe 6 and the inlet pipe 15 are connected to the interior of the mold base 1. The two connecting flanges 7 are fixedly connected to the ends of the drain pipe 6 and the inlet pipe 15 away from the mold base 1, respectively.

[0031] Two fixed brackets 2 are fixedly connected to the top of the mold base 1. Slide plates 14 are slidably connected inside the two fixed brackets 2.

[0034] Furthermore, when using this device, by connecting an external power source, two first electric push rods 5 are activated. The two first electric push rods 5 will drive the corresponding slide plates 14 to move. The movement of the two slide plates 14 will drive the first connecting plate 4 to move downward. The downward movement of the first connecting plate 4 will drive the multiple mold shaping plates 13 on it to move downward. When the multiple sealing plates 12 are in contact with the top of the mold base 1, the multiple mold shaping plates 13 will be located in the corresponding mold cavity 8, which makes it convenient for the operator to connect the injection pipes to the multiple injection pipes 3 respectively, so that the injection plastic is discharged into the multiple mold cavities 8 through the injection pipes 3.

[0036] With the cooperation of two connecting flanges 7, inlet pipe 15 and outlet pipe 6, coolant can be discharged from inlet pipe 15 into cooling cavity 16, so that coolant can surround the outside of mold cavity 8, thereby facilitating the cooling of inductor bases in multiple mold cavities 8. The coolant can carry away the heat in mold cavity 8. The inlet pipe 15 is installed higher than outlet pipe 6, which facilitates the circulation of coolant and further improves the cooling effect on inductor base mold.
