Description

Technical Field

[0001] This utility model belongs to the field of high-frequency head technology, and specifically relates to a novel high-frequency head forming mold structure. Background Technology

[0002] A low-frequency head (LNB) is a device used by satellite television to receive high-frequency signals and demodulate video information. It is also the first part of the common channel and is mounted on the satellite receiver by a bracket.

[0003] In the existing technology, the housing of the high-frequency head is generally formed by die casting. The housing of the high-frequency head generally consists of a main housing and an F-head housing. However, since both the main housing and the F-head housing have through holes, the molding die body needs to be equipped with core-pulling devices in two directions, that is, it is necessary to set up waveguide core-pulling components and F-head core-pulling components. Therefore, a molding die body can generally die-cast a maximum of 4 high-frequency head housings at one time, resulting in low production efficiency and a relatively complex design structure of the molding die body. Utility Model Content

[0004] This invention provides a novel high-frequency head forming mold structure, which can solve the problems pointed out in the background art.

[0005] A novel high-frequency head forming mold structure includes an upper template, a lower template, and a mold core assembly. The mold core assembly includes an upper mold core and a lower mold core, and a high-frequency head main housing forming cavity is provided between the upper mold core and the lower mold core. Waveguide sliding core pulling assemblies are slidably provided on both sides between the upper mold core and the lower mold core. The waveguide sliding core pulling assembly includes a slider and a plurality of waveguide core pullers connected to the inner side of the slider.

[0006] Preferably, the slider is slidably connected to the lower template.

[0007] Preferably, a small component forming cavity is provided between the upper mold core and the lower mold core.

[0008] Beneficial effects: This utility model provides a novel high-frequency head forming mold structure. The main shell of the high-frequency head is die-cast and integrally formed, and the F-head shell is connected and fixed to it in a secondary manner. Since this design structure only has waveguide sliding core-pulling components on both sides, multiple main shells can be die-cast at one time (at least 4 or more, such as 6 or 8), which can greatly improve the work efficiency, and the mold design is relatively simple.

[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0015] Example 1: As Figure 1-3 As shown, a novel high-frequency head forming mold structure includes an upper mold plate 1, a lower mold plate 2, a mold core assembly, guide pillars, and mold feet. The mold core assembly includes an upper mold core 31 and a lower mold core 32. The upper mold core 31 is connected to the upper mold plate 1, and the lower mold core 32 is connected to the lower mold plate 2. A high-frequency head main shell forming cavity 33 is provided between the upper mold core 31 and the lower mold core 32. The high-frequency head main shell forming cavity 33 is used for die casting of the high-frequency head main shell 5. Waveguide sliding core pulling assemblies are slidably provided on both sides between the upper mold core 31 and the lower mold core 32. The waveguide sliding core pulling assembly includes a slider 41 and a plurality of waveguide core pullers 42 connected to the inner side of the slider 41. Specifically, the slider 41 is slidably connected to the lower mold plate 2.

[0016] In some embodiments, a small part forming cavity 34 is provided between the upper mold core 31 and the lower mold core 32. The small part forming cavity 34 can form related small parts such as F-head shells or shielding covers, so as to achieve multiple uses of one item, improve production efficiency, and reduce the mold opening cost of enterprises.

[0017] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
