Description

Technical Field

[0001] This utility model belongs to the field of antenna manufacturing technology, specifically an antenna foaming device. Background Technology

[0002] In the current field of communication and electronic equipment, antennas are key components for signal transmission and reception, and their performance is crucial to the overall functionality of the equipment. However, existing antennas are formed by injection molding, and the molds only include upper and lower molds for antenna forming and some clamping devices. The injection holes are only opened on the upper or lower mold. When injecting material into a single injection hole, it is not convenient to vent the mold, which can easily lead to poor surface density of the foamed antenna or the appearance of pits. Utility Model Content

[0003] The purpose of this invention is to provide an antenna foaming device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an antenna foaming device, comprising an upper mold and a lower mold connected vertically for antenna forming, and further comprising an upper steam chamber, a lower steam chamber, and multiple inserts. The lower surface of the upper mold and the upper surface of the lower mold are provided with multiple steam holes communicating with the antenna forming cavity. The upper steam chamber and the lower steam chamber are detachably connected to the upper surface of the upper mold and the lower surface of the lower mold, respectively. The upper steam chamber and the lower steam chamber are connected to a steam output device via pipelines. The sidewalls of the upper mold and the lower mold are provided with grooves matching the embedding portions of the multiple inserts. The multiple grooves are respectively disposed on different sidewalls of the upper mold and the lower mold, and each groove is formed by splicing together sub-grooves distributed on the upper mold and the lower mold after assembly. Each groove communicates with the antenna forming cavity between the upper mold and the lower mold, and the inserts are fixedly embedded in the grooves.

[0005] Furthermore, the lower steam chamber sidewall is vertically rotatable via a pin and has multiple sets of symmetrical screws. The upper steam chamber sidewall has slots corresponding to the vertical positions of the screws. When the screws rotate upward, they can pass through the slots, and nuts are provided on the screws. The screws are fixed in the slots by tightening the nuts. By providing screws, when the nuts are tightened and the screws are fixed in the slots, the upper and lower steam chambers can be pulled together by the screws, thereby pressing the upper and lower molds together and ensuring the tightness of the fit between the upper and lower molds.

[0006] Furthermore, the upper mold and the lower mold are detachably connected to the upper steam chamber and the lower steam chamber respectively by bolts; after the upper mold and the upper steam chamber, and the lower mold and the lower steam chamber are connected by bolts respectively, the assembly of the device is improved, thus improving the ease of assembly.

[0007] Furthermore, the plurality of inserts are detachably connected to the sidewall of the upper or lower mold by bolts; the bolt connection of the inserts improves the tightness of the insert connection.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention provides multiple grooves on the upper and lower molds that communicate with the antenna forming cavity. During the injection process, the molding material can be injected into the antenna forming cavity simultaneously through these grooves, ensuring the fullness of the material injection. Furthermore, this invention provides an upper steam chamber and a lower steam chamber on the upper and lower molds respectively, ensuring steam circulation during the antenna forming process, thereby effectively guaranteeing the density and surface quality of the antenna.

[0015] 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.

[0016] Please see Figures 1-4This utility model provides a technical solution: an antenna foaming device, including an upper mold 1, a lower mold 2, an upper steam chamber 3, a lower steam chamber 4, and three inserts 5. The upper steam chamber 3 and the lower steam chamber 4 are fixedly connected to the upper surface of the upper mold 1 and the lower surface of the lower mold 2 respectively by bolts 6. The upper steam chamber 3 and the lower steam chamber 4 are connected to a steam output device through a steam transmission pipe 7. The lower surface of the upper mold 1 and the upper surface of the lower mold 2 are provided with multiple steam holes 8 communicating with the antenna forming cavity. The side wall of the lower steam chamber 4 is vertically rotatable by a pin and has multiple sets of symmetrical... The screw 9 has a slot 10 on the side wall of the upper steam chamber 3 corresponding to the vertical position of the screw 9. When the screw 9 rotates upward, it can pass through the slot 10. A nut 11 is provided on the screw 9. The screw 9 is fixed in the slot 10 by tightening the nut 11. When the nut 11 is tightened and the screw 9 is fixed in the slot 10, the upper steam chamber 3 and the lower steam chamber 4 can be pulled together by the screw 9, thereby pressing the upper mold 1 and the lower mold 2, ensuring the tightness of the fit between the upper mold 1 and the lower mold 2, and thus ensuring that the antenna is smoothly formed in the antenna forming cavity between the upper mold 1 and the lower mold 2.

[0017] The upper mold 1 and the lower mold 2 have grooves 12 on their side walls that match the embedding parts of the three inserts 5. Each groove 12 is a sub-groove distributed on the upper mold 1 and the lower mold 2, which are spliced ​​together after the upper mold 1 and the lower mold 2 are assembled. This further limits the connection between the upper mold 1 and the lower mold 2 when the inserts 5 are embedded, ensuring the quality of the antenna. Each groove 12 is connected to the antenna forming cavity between the upper mold 1 and the lower mold 2. In order to ensure the compactness of the antenna, it is necessary to pour material into the antenna forming cavity simultaneously from multiple angles. Therefore, the three grooves 12 are respectively set on three of the sides of the upper mold 1 and the lower mold 2. The inserts 5 are fixedly embedded in the grooves 12 and fixedly connected to the side wall of the upper mold 1 or the lower mold 2 by bolts 6. The shape of the end face of the embedding part of the insert 5 is set according to the shape of the antenna to be made.

[0018] In the specific antenna manufacturing process, the upper steam chamber 3 and lower steam chamber 4 are first assembled with the upper mold 1 and lower mold 2 respectively, and fastened with bolts 6. Then, the upper mold 1 and lower mold 2 are assembled together, and the screw 6 on the lower steam chamber 4 is rotated upward. The screw 6 is rotated to the slot 10 on the upper steam chamber 3 and tightened with nuts 11. Steam is then introduced into the upper steam chamber 3 and lower steam chamber 4 through the steam transmission pipe 7, and antenna foaming material is simultaneously poured into the antenna forming cavity between the upper mold 1 and lower mold 2 from multiple grooves 12. During the filling process, surface-treated fine aluminum wires can be used to stir deep into the grooves 12 to remove air from the antenna forming cavity and ensure that the antenna material is in full contact with the inner cavity of the device. Finally, the three inserts 5 are embedded into the corresponding grooves 12 and fixed with bolts 6, and the antenna foaming preparation process can be carried out.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
