Description

Technical Field

[0001] This invention relates to the field of antenna connector technology, and more particularly to a multi-part molding die for an antenna connector. Background Technology

[0002] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves.

[0003] Currently, existing antenna connection structures, such as Figure 1-2 As shown, the device includes a connecting body a, which comprises a small cylinder a1, a large cylinder a2, a large circular plate a3, and a small circular plate a4, which are coaxially fixed together from top to bottom. The small cylinder a1 has several annular grooves at equal intervals on its circumference. The large cylinder a2 has external threads on its periphery, and the diameter of the large cylinder a2 is smaller than the diameter of the large circular plate a3. A linear through hole a5 and a frustum-shaped hole a6 are coaxially formed in the middle of the connecting body a. The frustum-shaped hole a6 is connected to the linear through hole a5, and the upper diameter of the frustum-shaped hole a6 is equal to the diameter of the linear through hole a5, while the lower diameter of the frustum-shaped hole a6 is larger than its upper diameter.

[0004] The aforementioned antenna connection structure is made of copper. It is first cast into shape and then machined with a lathe to create the threaded surface. This requires multiple manual processing operations, resulting in high production costs and low production efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-stage molding die for antenna connectors, thereby solving the problems of high production cost and low production efficiency of existing copper antenna connectors.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a multi-stage molding die for an antenna connector, comprising an upper die, a lower die, and a hydraulic cylinder, wherein a guide post connects the upper die and the lower die; the upper die includes a top plate, a fixed template, and a fixed mold core; the lower die includes a bottom plate, a movable template, and a movable mold core; the hydraulic cylinder is disposed below the lower die, and its piston rod is connected to the bottom plate; its innovation lies in:

[0007] The top center of the moving mold core is provided with at least two bottom forming groups. Each bottom forming group includes several bottom forming grooves that are equally spaced on the center line of the wide side of the moving mold plate. Each bottom forming group also includes several positioning posts that are equally spaced inside the moving mold plate. The bottom forming grooves correspond vertically to the positioning posts. The top of the positioning post is a frustum, and the frustum penetrates into the center of the bottom forming groove. The bottom forming groove is located outside the frustum to form a bottom forming cavity, which is used to form the large circular plate, small circular plate and frustum-shaped hole of the antenna connector.

[0008] An upper forming group is provided at the top of each bottom forming group on the moving mold core. The upper forming group has a number of upper forming cavities that are the same as the number of bottom forming cavities. The upper forming cavities correspond one-to-one with the bottom forming cavities and are connected. The upper forming cavities are used to form the small cylinder, the large cylinder, the number of annular grooves equidistantly spaced on the circumference of the small cylinder, and the external threads on the periphery of the large cylinder of the antenna connector. A mandrel that penetrates the fixed mold core is vertically fixed on the fixed mold plate, with the same number of upper forming cavities as the fixed mold core. The mandrel includes an mounting part and a forming part. The outer diameter of the mounting part is larger than that of the forming part. The forming part extends into the bottom forming cavity to form the linear through hole of the antenna connector.

[0009] When the upper mold and lower mold are closed, the bottom of the core rod extends through the upper molding cavity into the bottom molding cavity and abuts against the frustum portion. At this time, the bottom end of the mounting part is pressed against the upper molding assembly. The bottom molding cavity, the upper molding cavity, and the core rod together form the antenna connector molding cavity.

[0010] Furthermore, the molding die also includes a gating system;

[0011] The gating system includes a gating gate and a main gating runner. The gating gate is located at the center of the moving mold core, and the main gating runner is located on the side of the bottom forming assembly on the moving mold core. The main gating runner is connected to both sides of each bottom forming groove of the bottom forming assembly by an auxiliary flow channel. The bottom surface of the main gating runner is located in the upper middle part of the bottom forming groove to minimize the thickness of waste material and reduce production costs.

[0012] Furthermore, a support column is provided in the middle of the pouring gate, and the outer diameter of the support column is smaller than the inner diameter of the pouring gate.

[0013] Furthermore, the upper forming assembly includes two upper forming blocks that are symmetrical about the center line of the wide side of the moving mold plate and are slidably disposed on the moving mold core. Each upper forming block has several grooves on its inner side. When the two upper forming blocks move to fit together on the moving mold core, the two grooves on the two upper forming blocks are joined together to form the upper forming cavity.

[0014] Furthermore, the two upper forming blocks are provided with inclined holes on the side away from the bottom forming cavity, and inclined guide posts with the inclined holes on the same inclined line are respectively installed on both sides of the bottom of the fixed mold plate. The upper forming blocks are moved on both sides of the moving mold core by the inclined guide posts.

[0015] Furthermore, a rectangular positioning block is provided at the bottom end of the mandrel; a rectangular positioning groove with an upward opening is also provided at the top of the positioning post for accommodating the rectangular positioning block.

[0016] Furthermore, its molding process includes the following steps:

[0017] S1: Start the hydraulic cylinder to drive the lower mold to move upward, so that the bottom of the inclined guide post enters the inclined hole of the upper forming block, and the upper forming block moves inward accordingly.

[0018] S2: Continue driving the lower mold to move upward until the rectangular positioning block of the core rod is aligned with the rectangular positioning groove of the corresponding positioning post and locked in place. The upper and lower molds are then closed. The inner sides of the two symmetrical upper forming blocks are just touching. At this time, the bottom end of the upper forming block is touching and coaxial with the top end of the bottom forming groove. At the same time, the top surface of the upper forming block is just touching the bottom end of the mounting part of the core rod. The antenna connector forming cavity is then assembled.

[0019] S3: The alloy solution is injected from the pouring port and guided evenly into the main pouring channel through the support column. The alloy solution enters the antenna connector molding cavity from the auxiliary channel.

[0020] S4: After all the antenna connector molding cavities are filled with alloy solution, stop the injection. After cooling, start the hydraulic cylinder to drive the lower mold to descend for demolding. At least two bottom molding groups will have a semi-finished product, and the semi-finished product will include several antenna connectors and waste material connected between the antenna connectors.

[0021] S5: Cut off several antenna connectors from the semi-finished product to become antenna connectors to be processed;

[0022] S6: Multiple antenna connectors to be processed are simultaneously fed into the antenna parts deburring mechanism for deburring, forming finished antenna connectors.

[0023] The advantages of this invention are:

[0024] In this invention, a lower-cost alloy material is used, which greatly reduces the material input cost compared to the existing copper antenna connection structure. Moreover, the casting process described above allows for the production of multiple antenna connectors at once. Compared to the existing copper antenna connection structure, the complexity of the molding process is also greatly reduced. This significantly improves production efficiency and greatly reduces labor and production input costs when mass-producing antenna connectors. Attached Figure Description

[0036] The top of the positioning post 42 is a frustum, and the frustum extends into the center of the bottom forming groove 41. The bottom forming groove 41, located outside the frustum, forms a bottom forming cavity 44, which is used to form the large circular plate, the small circular plate, and the frustum-shaped hole.

[0037] A rectangular positioning groove 43 with an upward opening is also provided on the top of the positioning post 42 to accommodate the rectangular positioning block 73.

[0038] An upper forming group is provided at the top of each bottom forming group on the moving mold core 4.

The installation section 71 is located inside the fixed template 2, and the forming section 72 is located at the bottom of the fixed mold core 3. The forming section 72 is used to form the linear through hole of the antenna connector. A rectangular positioning block 73 is also provided at the center of the bottom end of the forming section 72 of the core rod.

[0042] The molding die also includes a gating system 8.

[0043] The gating system 8 includes a top injection channel 81, a sprue 82, and a main gating channel 83.

[0045] Two upper forming blocks 51 are provided with inclined holes 54 on the side away from the bottom forming cavity 44. Inclined guide pillars with the inclined holes 54 are installed on the bottom sides of the fixed template 2 respectively. The inclined guide pillars drive the upper forming blocks 51 to move closer or further away from each other on both sides of the moving mold core 4. U-shaped grooves 55 are provided on both sides of the moving template 5 and the bottom plate 6 to accommodate the inlet and outlet of the inclined guide pillars.
