Description

Technical Field

[0001] This utility model relates to the field of pin manufacturing technology, and in particular to a molding tooling for manufacturing connector pins. Background Technology

[0002] Connector pins are core conductive components in electronic devices, and their molding precision directly affects connector performance. Traditional molding fixtures typically have only a single molding cavity, processing only one pin at a time, which is insufficient to meet the high-throughput demands of the modern electronics industry. In some multi-cavity molding fixtures, the mold base is often an integral structure; when one cavity is damaged, the entire mold base must be scrapped and replaced, resulting in high maintenance costs per operation.

[0003] To address this, we designed a molding tooling for connector pin production. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a forming tool for connector pin production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A molding tooling for connector pin manufacturing, comprising: The base has an assembly cavity at the rear of its top surface and a receiving cavity at the front of its top surface. A fixed mold base is detachably installed in the assembly cavity, and its top surface is provided with multiple molding cavities spaced apart along the left and right directions; A replaceable loading plate is movably placed in the receiving cavity at the bottom; the replaceable loading plate is provided with multiple loading holes with open rear ends, and each loading hole corresponds to a molding cavity.

[0006] Furthermore, a support unit is provided at the bottom of the receiving cavity to flexibly support the replaceable loading plate.

[0007] Furthermore, the support unit includes: The support plate is movably embedded within the receiving cavity; Multiple guide posts are vertically fixed to the lower surface of the support plate; Springs are sleeved on the outside of each guide post, with their lower ends embedded in the mounting holes at the bottom of the receiving cavity.

[0008] Furthermore, the fixed mold base is composed of multiple independent molding units arranged in the left-right direction, and each molding unit has an upper horizontal groove on the rear section of its bottom surface and a vertical groove on its rear end surface.

[0009] Furthermore, the upper section of the rear sidewall of the assembly cavity is provided with a vertical slider, which is inserted into and cooperates with the vertical slide groove; the bottom surface of the assembly cavity is provided with a lower horizontal slide groove; the horizontal slider is slidably connected in the lower horizontal slide groove and is inserted into and cooperates with the upper horizontal slide groove.

[0010] Furthermore, an adjusting rod is rotatably connected to the rear end of the horizontal slider. The adjusting rod passes through the rear sidewall of the assembly cavity and is threaded into the rear sidewall.

[0011] Furthermore, the adjusting rod includes a front smooth rod section and a rear threaded section, wherein the diameter of the rear threaded section is larger than the diameter of the front smooth rod section.

[0012] Furthermore, each of the molding units has a threaded hole on its top surface for installing lifting tools during disassembly.

[0013] Furthermore, the loading hole of the replaceable loading plate has a flared taper at the rear end, with a taper angle of 30-60°.

[0014] Furthermore, the mounting hole is a threaded through hole, with a screw plug screwed into its bottom, which abuts against the lower end of the spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The fixed mold base has multiple molding cavities spaced apart, which correspond one-to-one with the loading holes of the replaceable loading plate, enabling multiple pin materials to be pressed simultaneously in a single operation, thus improving production efficiency. 2. The fixed mold base is assembled from independent molding units. When a single molding cavity is damaged, only the corresponding unit needs to be replaced, avoiding the cost waste caused by scrapping the traditional whole mold base and reducing maintenance costs. At the same time, its top surface threaded hole design supports quick disassembly tool installation, which facilitates the replacement of damaged molding units. 3. The spring in the support unit provides elastic cushioning, which can move down with the insert during the pressing process to prevent the insert from bending at the junction of the pressed and unpressed parts; at the same time, after the pressing is completed, the spring rebounds and lifts the replaceable loading plate, which helps the forming insert to leave the forming cavity.

[0019] Example 1, in conjunction with Appendix Figure 1-7 A molding tooling for manufacturing connector pins, comprising: The base 1 has an assembly cavity 11 at the rear of its top surface and a receiving cavity 12 at the front.

[0020] The fixed mold base 2 is detachably installed in the assembly cavity 11, and its top surface has multiple forming cavities 21 spaced apart in the left and right direction (10 are shown in the attached figure of this embodiment) for the plastic deformation of the pin.

[0021] The replaceable loading plate 3 is movably placed in the receiving cavity 12 at the bottom. Multiple loading holes 31 with open rear ends are opened on its rear end face. Each hole corresponds to the forming cavity 21 and is used to pre-load the pins and to radially position the pins.

[0022] As needed, the rear end of the loading hole 31 is provided with a flared taper, for example, a taper angle of 30-60°, to guide the pin to be smoothly inserted into the loading hole 31.

[0023] In one possible implementation, the fixed mold base 2 consists of multiple independent molding units 201.

[0024] Each molding unit 201 has a horizontal sliding groove 22 on the rear section of its bottom surface and a vertical sliding groove 23 on its rear end surface; a threaded hole 24 is provided on the top surface for installing a lifting tool. That is, when replacing the molding unit 201, a lifting tool can be screwed into the threaded hole 24 and the molding unit 201 can be lifted upward, so that the vertical sliding groove 23 of the molding unit 201 is disengaged from the vertical slider 15.

[0025] A vertical slider 15 is provided on the upper section of the rear side wall of the assembly cavity 11, which is inserted into the vertical slide groove 23; a lower horizontal slide groove 16 is provided on its bottom surface, which is inserted into the upper horizontal slide groove 22 through a horizontal slider 17. Specifically, the length of the lower horizontal slide groove 16 is twice or more the length of the upper horizontal slide groove 22, ensuring that the horizontal slider 17 can completely disengage from the upper horizontal slide groove 22 and release the restriction of the corresponding molding unit 201.

[0026] The horizontal slider 17 is rotatably connected to the adjusting rod 18 at its rear end. The rod passes through the rear side wall of the assembly cavity 11 and is threaded into it. Furthermore, the adjusting rod 18 is divided into a front smooth rod section 181 and a rear threaded section 182.

[0027] Depending on the requirements, the above-mentioned groove can be a dovetail or a T-groove.

[0028] Working principle of replacing molding unit 201: Disassembly operation: Rotate the adjusting rod 18 to move the horizontal slider 17 backward to the state of disengaging the threaded engagement. Then pull the adjusting rod 18 backward to disengage the horizontal slider 17 from the upper horizontal slide groove 22. At this time, screw the lifting tool into the threaded hole 24 and pull the lifting tool upward. The lifting tool will drive the forming unit 201, causing the vertical slide groove 23 of the forming unit 201 to disengage from the vertical slider 15, thus completing the disassembly operation of the forming unit 201. Installation operation: Align the vertical slide groove 23 of the molding unit 201 with the vertical slider 15 on the assembly cavity 11, then press the molding unit 201 down to the bottom, and finally push the adjusting rod 18 forward to move the horizontal slider 17 forward so that the horizontal slider 17 is inserted into the upper horizontal slide groove 22. Then rotate the adjusting rod 18 to move the horizontal slider 17 forward and align it with the axial position of the adjusting rod 18.

[0029] Working principle: Insert the pin into the loading hole 31, and then place the replaceable loading plate 3 into the receiving cavity 12. At this time, the pins to be pressed are placed in the forming cavity 21 one by one. Then, the pressing operation of the pins to be pressed is completed by pressing down with an external press. Finally, the external press returns and the replaceable loading plate 3 is removed, so that the formed pins are removed from the loading hole 31.

[0030] It should be noted that, in order to further improve production efficiency, two or more replaceable loading plates 3 can be prepared. During the molding process of one replaceable loading plate 3, the other replaceable loading plate 3 is inserted with pins.

[0031] Example 2, in conjunction with Appendix Figure 3 A molding tooling for connector pin production, wherein a replaceable loading plate 3 is fixed at a fixed height during operation, causes a slight bending at the junction of the molding and unmolded areas of the pin due to a certain height difference between the central axis before and after molding of the pin end to be molded. Therefore, this embodiment is optimized based on embodiment one. A support unit 13 is provided at the bottom of the inner cavity of the receiving cavity 12, which includes: Support plate 131, movable embedded receiving cavity 12.

[0032] Multiple guide posts 132 (e.g., 6, distributed in a matrix) are vertically fixed to the bottom surface of the support plate 131.

[0033] Spring 133 is sleeved on the outside of guide post 132, and its lower end is embedded in the mounting hole 14 at the bottom of receiving cavity 12.

[0034] As needed, mounting hole 14 is a threaded through hole, with a screw plug screwed into the bottom. The screw plug abuts against the lower end of spring 133, making it easy to adjust the spring force.

[0035] In this embodiment, during the pressing operation of the end of the insert pin to be pressed, when the central axis of the end of the insert pin to be pressed moves downward, the insert pin can drive the replaceable loading plate 3 to compress the spring 133 downward, effectively solving the problem of slight bending at the junction of the pressing area and the unpressed area of ​​the insert pin; at the same time, after the external press returns after the pressing is completed, the upward pressure of the spring 133 on the support plate 131 and the replaceable loading plate 3 also helps the formed insert pin to disengage from the loading hole 31.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects.
