Description

Technical Field

[0001] This utility model relates to the field of antenna mast manufacturing technology, and in particular to an injection molding mold for an antenna mast. Background Technology

[0002] An antenna mast is a product used to protect an antenna. The antenna is installed inside the antenna mast, and antenna masts are commonly used on routers.

[0003] In the prior art, there is a molding die for antenna masts, which includes an upper mold core, a lower mold core, and a side core-pulling mechanism. The upper mold core is provided with multiple upper molding grooves and upper injection channels connected to the multiple upper molding grooves to simultaneously injection mold the upper parts of multiple antenna masts. In this structure, the single injection gate setting can easily lead to uneven distribution of molten glue, thus affecting the aesthetic appearance of the antenna mast. Furthermore, the side core-pulling mechanism includes a fixing plate, a slider, and a hydraulic cylinder. One end of the fixing plate extends outward beyond the lower mold plate, and the hydraulic cylinder is located at the end of the fixing plate away from the lower mold plate. In this structure, the overall size of the mold is large, occupies a lot of space, and is inconvenient for storage. In addition, the structure is relatively cumbersome, which brings inconvenience to the assembly of the mold, because it uses multiple positioning parts to position the fixing plate on the lower mold plate.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0005] In view of the above, this utility model addresses the deficiencies of the existing technology and its main objective is to provide an injection molding mold for antenna masts. The mold features six sets of molding grooves arranged in a three-row, two-column pattern on both the upper and lower molding grooves, and is equipped with two side core-pulling mechanisms. This allows the mold to mold twelve antenna masts at once, resulting in high production efficiency. Furthermore, the gating system has six gating ports connected to the upper molding grooves, allowing for more uniform gating and improved product quality. Additionally, a hydraulic cylinder is located at the bottom of the mounting plate and moves the slider via a linkage, making the overall mold structure more compact. The second clearance groove further reduces the overall size of the mold and allows for better positioning of the mounting plate with the lower mold plate, providing a positioning function. The structural design is ingenious.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An injection molding mold for an antenna mast includes an upper mold, a lower mold, a side core-pulling mechanism, and a gating system. The upper mold includes an upper template and an upper mold core fixed to the upper template. The lower mold includes a lower template and a lower mold core fixed to the lower template.

The bottom of the mounting plate has an upwardly recessed mounting position for the hydraulic cylinder. The hydraulic cylinder is positioned at the mounting position. Correspondingly, a second clearance groove is provided on the side of the lower template for the hydraulic cylinder to pass through. The end of the hydraulic cylinder closest to the lower template is inserted into the second clearance groove. The end of the hydraulic cylinder furthest from the lower template is connected to a linkage via a piston rod. The linkage is connected to a connecting rod connected to the slider. The hydraulic cylinder drives the linkage to move, thereby causing the slider to slide within the sliding groove. The shovel base is located on the upper template.

The core is disposed in the core mounting seat, and the top of the core mounting seat has a slot that matches the shovel base. The shovel base can be inserted into the slot to lock the slider.

[0015] As a preferred embodiment, the sliding seat has a positioning protrusion at one end near the lower mold core, and the core mounting seat has a positioning groove at one end away from the lower mold core. The core mounting seat is fixed to the sliding seat by the cooperation of the positioning protrusion and the positioning groove. The core passes through the positioning groove into the core mounting seat. The end of the core near the sliding seat is provided with an end head, which is constrained by the positioning groove. Correspondingly, the positioning protrusion has a retaining groove for retaining the end head.

[0016] As a preferred embodiment, the top of the lower template is recessed into a third groove, and the lower mold core is fixed in the third groove.

[0017] As a preferred embodiment, the sliding groove has a mounting groove for positioning the insert at the end near the first clearance groove, the insert is fixed in the mounting groove, and the movement of the slider is restricted to the end of the insert away from the lower mold core.

[0018] As a preferred embodiment, the mounting plate has a third clearance groove on the side away from the lower mold core for the linkage component to avoid, and the linkage component can move into the third clearance groove.

[0019] As a preferred embodiment, both the upper mold core and the lower mold core are provided with cooling channels.

[0020] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
