Description

Technical Field

[0001] This utility model belongs to the field of electronic connector manufacturing technology, and in particular relates to an electronic connector injection molding machine with a quantitative feeding structure. Background Technology

[0002] Electronic connector injection molding machines are specialized equipment used for molding plastic parts for electronic connectors. Their core systems include an injection unit, a mold clamping mechanism, a temperature control system, and a mold positioning component. They can precisely control parameters such as injection volume, pressure, and mold temperature, and are adapted to the miniaturization of connector plastic parts.

[0003] In the injection molding production of electronic connectors, the injection molding machine is a key piece of equipment for molding plastic parts. However, injection molding machines often lack a precise quantitative feeding structure, resulting in unstable raw material feeding. This leads to dimensional deviations and insufficient filling in the molded connector shells, insulating bases, and other components. Therefore, it is necessary to design an electronic connector injection molding machine with a quantitative feeding structure. This structure can control the raw material feeding, ensure that the molded plastic parts of the electronic connector are dimensionally complete and fully filled, improve the insulation performance of the product, and at the same time avoid excessive or insufficient raw materials, reducing waste and lowering production costs. Utility Model Content

[0004] The purpose of this invention is to provide an electronic connector injection molding machine with a quantitative feeding structure, which has the advantages of controlling the amount of raw material fed, ensuring the relatively complete molding size of the electronic connector plastic parts, reducing material waste, and lowering production costs, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An electronic connector injection molding machine with a quantitative feeding structure includes an injection cylinder installed on the rear side of the top of the injection molding machine, a support frame provided on the rear side of the injection molding machine, a spiral feeding rod installed on the top of the support frame, a power component installed on the rear side of the top of the support frame, the output shaft of the power component being fixedly connected to the spiral feeding rod through a bearing seat and a coupling, a storage hopper being connected to the rear side of the top of the spiral feeding rod, a discharge port being connected to the front side of the bottom of the spiral feeding rod, the injection cylinder being connected to the discharge port, a lower base plate being fixedly connected to the bottom of the support frame, and a connecting sleeve being sleeved on the surface of the spiral feeding rod.

[0006] Preferably, the support frame at the top of the support frame is fixedly connected to a reinforcing member, and the central axis of the spiral feed rod is located in the inner cavity of the reinforcing member.

[0007] Preferably, an adjusting block is provided through the surface of the lower base plate, and the bottom of the adjusting block is in contact with the ground.

[0008] Preferably, a horizontal plate is fixedly connected to the surface of the connecting sleeve, and an L-shaped plate is fixedly connected to the rear side of the injection molding cylinder surface by bolts, and the horizontal plate and the L-shaped plate are fixedly connected by bolts.

[0009] Preferably, both of the adjusting blocks have nuts threaded onto their surfaces, with the ground of the nuts contacting the top of the lower base plate.

[0010] The beneficial effects of this utility model are: 1. This utility model involves pouring raw materials into the inner cavity of the storage hopper, starting the power assembly, which drives the spiral feeding rod to rotate, and cooperating with the discharge port to enter the inner cavity of the injection molding cylinder. This ensures that the amount of raw material entering the inner cavity of the injection molding cylinder remains consistent. Finally, the injection molding machine heats and melts the raw material and performs injection molding. This achieves the purpose of controlling the amount of raw material conveyed, ensuring that the plastic parts of the electronic connector are molded with relatively complete dimensions, reducing raw material waste, and lowering production costs. 2. This utility model uses the combination of a horizontal plate and an L-shaped plate. Since the material outlet of the discharge port is connected to the material outlet of the injection cylinder, when the horizontal plate and the L-shaped plate are fixedly connected by bolts, it ensures that the material at the discharge port will not spill when the screw feeder shakes during operation, and the material will all enter the inner cavity of the injection cylinder, thus improving the stability of the screw feeder during use.

[0013] In the following description, embodiments of the electronic connector injection molding machine with a quantitative feeding structure of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-5 This invention illustrates an embodiment of an electronic connector injection molding machine with a quantitative feeding structure. It includes an injection cylinder 2 mounted on the rear top of the injection molding machine 1. A support frame 3 is located on the rear side of the injection molding machine 1. A spiral feed rod 4 is mounted on the top of the support frame 3. A power assembly 5 is mounted on the rear top of the support frame 3. The output shaft of the power assembly 5 is fixedly connected to the spiral feed rod 4 via a bearing seat and a coupling. A storage hopper 6 is connected to the rear top of the spiral feed rod 4. A reinforcing member 7 is fixedly connected to the support frame at the top of the support frame 3. The central shaft of the spiral feed rod 4 is located within the cavity of the reinforcing member 7. An outlet 8 is connected to the front bottom of the spiral feed rod 4. The injection cylinder 2 is connected to the outlet 8. A lower base plate 9 is fixedly connected to the bottom of the support frame 3. An adjusting block 10 is provided through the surface of the lower base plate 9. The bottom of the adjusting block 10 is in contact with the ground. The surface of the spiral feed rod 4 is fitted with a connecting sleeve 11. A horizontal plate 12 is fixedly connected to the surface of the connecting sleeve 11. An L-shaped plate 13 is fixedly connected to the rear side of the injection cylinder 2 by bolts. The horizontal plate 12 and the L-shaped plate 13 are fixedly connected by bolts. Through the cooperation of the horizontal plate 12 and the L-shaped plate 13, since the material outlet 8 is connected to the material outlet of the injection cylinder 2, when the horizontal plate 12 and the L-shaped plate 13 are fixedly connected by bolts, it is ensured that the material at the material outlet 8 will not spill when the spiral feed rod 4 shakes during operation. The material will all enter the inner cavity of the injection cylinder 2, which improves the stability of the spiral feed rod 4 during use. The surfaces of the two adjusting blocks 10 are threaded with nuts 14. The ground of the nuts 14 is in contact with the top of the bottom plate 9.

[0015] Working Principle: When using this utility model, the operator first pours the raw material into the inner cavity of the storage hopper 6, turns on the power assembly 5, and its output shaft drives the screw feeder 4 to rotate through the bearing. During the rotation of the screw feeder 4, the raw material in the storage hopper 6 is conveyed along its axial direction. During the conveying process, the central axis of the screw feeder 4 is located in the inner cavity of the reinforcement 7. The reinforcement 7 provides support and reinforcement for the screw feeder 4, ensuring its stable rotation. The raw material is conveyed to the discharge port 8 at the bottom front of the screw feeder 4, and enters the inner cavity of the injection molding cylinder 2 that is connected to it through the discharge port 8. By controlling the operation of the power assembly 5, the conveying amount of raw material can be controlled, so that each time... The amount of material entering the inner cavity of the injection cylinder 2 remains consistent. Meanwhile, the horizontal plate 12 on the surface of the connecting sleeve 11 is fixedly connected to the L-shaped plate 13 on the rear side of the surface of the injection cylinder 2 by bolts, ensuring that the material at the outlet 8 will not spill when the spiral feed rod 4 is working, and all of it will enter the inner cavity of the injection cylinder 2, further ensuring the stability and accuracy of the raw material conveying. Finally, the injection molding machine 1 heats and melts the raw material entering the injection cylinder 2 and performs injection molding to produce plastic parts for electronic connectors. In addition, the adjusting block 10 on the surface of the lower base plate 9 can adjust the height and level of the entire device, and the nut 14 is used to fix the position of the adjusting block 10 to ensure that the operation will not shake.

[0016] In summary, this electronic connector injection molding machine with a quantitative feeding structure, by pouring raw materials into the inner cavity of the storage hopper 6 and starting the power component 5, drives the spiral feed rod 4 to rotate, which, in conjunction with the discharge port 8, enters the inner cavity of the injection cylinder 2. This ensures that the amount of raw material entering the inner cavity of the injection cylinder 2 remains consistent. Finally, the injection molding machine 1 heats and melts the raw material and performs injection molding. This achieves the goals of controlling the amount of raw material fed, ensuring relatively complete molding dimensions of the electronic connector plastic parts, reducing material waste, and lowering production costs.
