Technical Field

[0001] The invention relates to the technical field of cable joints, in particular to a cable insulation joint forming device. Background Art

[0002] The functions of cable insulation joints mainly include electrical connection, mechanical protection and environmental protection. Cable insulation joints are one of the accessories of cable lines. The safety hazards of cable applications are basically in the connection. Poor joints often cause important hidden dangers such as large line loss, heating, leakage and even fire. The cylinder of existing cable insulation joints is usually produced by injection molding. During the injection molding, the connectors at both ends of the cable are inserted into the mold seat, and the mold seat is used to injection mold the insulation joint.

[0003] At present, after the cable insulation joint is molded and molded, the mold needs to be demolded, but demolding is time-consuming and laborious, so a release agent is applied to the inside of the mold during processing and molding in the workshop. It is a functional substance used between the mold and the finished product. Its main function is to prevent molded products, laminated products, etc. made of rubber, plastic, elastomer or other materials from adhering to the mold or other board surfaces, so that they are easy to detach. However, the operator has a large workload in the process of brushing back and forth, which also reduces the production efficiency of the workshop. In addition, after demolding, due to the gap between the upper and lower molds during the mold closing process, burrs or adhesion of release agent residues will occur at the mold closing. At this time, the operator is also required to clean the periphery of the cable insulation joint, and continuous flipping operation is required during cleaning, and the cleaning intensity is high.

A storage bottom box 18 is fixedly installed on the bottom side of the spray seat 32 on the spray plate 12, and the sprayed overflow liquid is stored and concentrated through the storage bottom box 18.

[0030] Working principle: The upper mold base 30 and the lower mold base 20 are matched and molded, and the cable connectors are inserted into both ends of the mold. The worker then uses the U-shaped structure tool in the workshop to clamp and mold the upper and lower mold bases, and injects the molten material into the grouting hole of the upper mold base 30. After the mold is molded, the electric telescopic rod 14 under the connecting plate 13 drives the arc cable plate 15 to fix and support the cables on the cable fixing seat 16, and the servo motor 47 drives the limiting movable column 45 in the rotating groove 44 on the rotating plate 43 to move in the flip groove 42. The rotating plate 43 drives the upper mold base 30 under the support frame 31 to lift through the flip groove 42. Then, when the rotating plate 43 moves through the arc section of the flip groove 42, the rotating limiting seat 46 is used to realize the flipping movement, so that the support frame 31 drives the upper mold base 30 to demould and flip. When the rotating plate 43 continues to rotate, the support frame 31 pushes the upper mold base 30 horizontally, so that the upper mold base 30 faces the spray seat 32 on the spray plate 12. The release agent box 33 on the spray plate 12 cooperates with the spray seat 32 to spray the interior of the upper mold base 30, so workers do not need to apply the release agent, which reduces the labor intensity of the operators, and the release agent that is sprayed and overflowed is stored in the storage bottom box 18; When the upper mold base 30 is lifted and turned over, the first motor 54 drives the driving gear 23 on the rotating shaft 24 to rotate, and the driving gear 23 meshes to drive the arc-shaped rack plate 22 on the lower mold base 20 to turn over, and the arc-shaped fixed base 50, the fixed slide groove 52 and the fixed slide block 53 drive the lower mold base 20 to rotate.

After reverse movement, the gas in the cleaning cylinder 60 is pressed out through the piston plate 67, and the lower mold base 20 is blown and cleaned through the L-shaped air outlet pipe 68 and the nozzle on the cleaning seat 17, so that the scraped and cleaned debris is cleaned out from the lower mold base 20. After cleaning, the formed cable insulation joint is taken out through the arc cable plate 15 to prepare for the next molding. The design is reasonable and ingenious, and the structure is simple and stable.
