Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a device for integrally molding relay contacts and injection molded parts. Background Technology

[0002] Relays are key components widely used in power control, automation systems, and electronic equipment. The way their contacts are joined to the injection-molded parts directly affects the relay's mechanical strength, conductivity, and long-term reliability. Traditional relay manufacturing processes typically employ a split-assembly method, where the metal contacts and plastic parts are manufactured separately and then joined together through riveting, welding, or insert injection molding. This results in insufficient robustness between the relay contacts and the injection-molded parts.

[0003] While existing equipment for integral molding of relay contacts and injection molded parts can integrally mold the contacts and injection molded parts, after the contacts are placed, due to differences in the materials of the structure or placement deviations, the contacts and injection molded parts may separate after injection molding. This results in the contacts remaining in the mold cavity when the integral part is clamped. If this defect is not detected in time, it will lead to an increase in the defect rate of subsequent production. At the same time, the contacts remaining in the mold will also affect the normal operation of subsequent injection molding, thus affecting the production efficiency of injection molding of relay contacts and injection molded parts.

[0040] 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.

[0041] This utility model provides, for example Figure 1-3 The illustrated equipment for integral molding of relay contacts and injection molded parts includes a rotary table 1, injection mold 2, injection mold 3, mechanical gripper 4, clamping mechanism 5, positioning mechanism 6, and detection camera 7. Multiple injection molds 2 are mounted on the upper surface of the rotary table 1 to facilitate multi-station injection molding. The injection mold 3 is mounted above one of the injection molds 2. By rotating the rotary table 1, the injection mold 3 can sequentially injection mold the injection molds 2 on the rotary table 1. The mechanical gripper 4 is mounted above another injection mold 2. The mechanical gripper 4 facilitates the... The relay contact can be moved onto the injection mold 2, so that when the injection mold 3 is used for injection molding, the relay contact and the injection molten metal can be integrally injection molded. The clamping mechanism 5 is installed on one side of the rotary table 1. The clamping mechanism 5 is used for telescopic clamping of the integral molded part. The positioning mechanism 6 is installed on the top of the clamping mechanism 5. The detection camera 7 is snapped onto one end of the positioning mechanism 6. The detection camera 7 is used for defect detection of the integral molded part of the relay contact and the injection molded part, to prevent some relay contacts from failing to fuse with the injection molded part, resulting in the relay contacts being left in the inner cavity of the injection mold 2, which would affect the subsequent injection molding of the integral molded part.

[0042] The clamping mechanism 5 includes an electric telescopic cylinder 51 and a clamping clamp 52. The electric telescopic cylinder 51 is fixed to one side of the rotating worktable 1 by a bracket. The clamping clamp 52 is installed at the telescopic end of the electric telescopic cylinder 51. The clamping clamp 52 is an existing finished clamping body structure. The clamping clamp 52 is used to clamp the one-piece molded part. The bottom of the clamping clamp 52 is provided with a feeding frame 8. The feeding frame 8 is fixed obliquely to one side of the rotating worktable 1. After the clamping clamp 52 clamps the injection molded one-piece molded part from the injection mold 2 by the drive of the electric telescopic cylinder 51, it retracts and is photographed by the detection camera 7. If the inspection is qualified, the clamping clamp 52 releases the one-piece molded part so that the one-piece molded part can fall into the inner cavity of the feeding frame 8 for feeding. If the inspection is unqualified, the detection camera 7 is connected to the controller so that the controller can stop the rotating worktable 1, mechanical gripper 4 and other structures on the equipment, so as to facilitate timely cleaning of the residual contact pieces on the injection mold 2.

[0043] In addition, the positioning mechanism 6 is installed on the top of the electric telescopic cylinder 51. The positioning mechanism 6 includes a support frame 61, a slot 62, a limiting component 63, and a pulling component 64. The support frame 61 is fixed to the top of the electric telescopic cylinder 51. The slot 62 is opened at one end of the support frame 61. The detection camera 7 is snapped into the inner cavity of the slot 62. The detection camera 7 is connected to an external power supply through a controller. The limiting component 63 is set on both sides of the inner cavity of the slot 62. The pulling component 64 is connected to the two limiting components 63. By pulling the component 64, it is easy to release the limiting component 63 from the detection camera 7, so that the detection camera 7 can be easily installed and removed from one end of the support frame 61.

[0044] Specifically, the slot 62 includes a connecting slot 621 and a bearing slot 622. The connecting slot 621 is opened at one end of the support frame 61, and the bearing slot 622 is opened on both sides of the top of the connecting slot 621. The detection camera 7 is snapped into the inner cavity of the bearing slot 622. The opening of the connecting slot 621 makes it convenient to remove the detection camera 7 from the inner cavity of the bearing slot 622.

[0045] The limiting component 63 is slidably inserted into the inner wall of the bearing groove 622. The limiting component 63 includes a limiting rod 631, rubber rings 632 and a compression spring 633. The limiting rod 631 is slidably inserted into the top of the bearing groove 622 and is slidably inserted into one end of the support frame 61. Multiple rubber rings 632 are fixedly inserted into one end of the limiting rod 631 and are slidably inserted into one end of the support frame 61. This allows the rubber rings 632 to be placed on the top of the detection camera 7, reducing pressure damage to the sides of the detection camera 7. Furthermore, the insertion of the limiting rod 631 into the inner walls of both sides of the bearing groove 622 ensures that the detection camera 7 can be stably placed in the inner cavity of the bearing groove 622. The compression spring 633 is sleeved on the outer wall of the limiting rod 631.

[0046] The pulling assembly 64 includes a movable groove 641, an actuating block 642, and a connecting plate 643. The movable groove 641 is formed on the upper surface of the support frame 61. The actuating block 642 slides through the inner cavity of the movable groove 641. The connecting plate 643 is fixedly inserted and connected to the middle of the two limiting rods 631, and slidably inserted and connected to the middle of the support frame 61. One end of the compression spring 633 is fixedly connected to the outer wall of the connecting plate 643, and the other end of the compression spring 633 abuts against the inner wall of the movable groove 641. The compression spring 633 always tends to drive the limiting rod 631 into the bearing groove 622. The elasticity of the compression spring 633 makes it easy for the connecting plate 643 to push the two limiting rods 631 stably, so that the limiting rods 631 can stably limit the detection camera 7. By pulling the lever block 642, the limiting rod 631 slides out of the inner cavity of the bearing groove 622, making it easy to remove the detection camera 7 from the inner cavity of the bearing groove 622 and improving the convenience of replacing the detection camera 7.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
