[0001] The present invention relates to the technical field of cable molding, and in particular to an extrusion molding device for a charging cable of a new energy vehicle. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. Car charging cables are mainly used for charging cars. In the process of producing cables, the cables need to be placed in an extrusion molding device, and the plasticized raw materials are extruded through the device to extrude an insulating layer and a protective cover on the cable.

[0003] When in use, the existing cable extrusion molding equipment cannot heat and insulate the molten raw materials, and does not stir the molten raw materials, which makes the raw materials easy to solidify. The uneven composition of the raw materials will also affect the extruded protective cover, which greatly reduces the production qualification rate. At the same time, when the existing cable extrusion molding equipment starts to discharge materials, there is air inside the head, and the cover cannot be completely formed, causing great waste.

The surface of the particle stirring blade 574 is slidably connected to the inner wall of the shell 51, and the particle stirring blade 574 is configured to be spiral. When the motor 571 is started, the output end of the motor 571 drives the rotating shaft 573 to rotate, and drives the particle stirring blade 574 to rotate, thereby stirring the granular raw material, so that the raw material is evenly heated during heating, and at the same time, the raw material is prevented from agglomerating. In addition, the spiral particle stirring blade 574 has a longer time for particles to roll down on its surface, which can delay the falling of the raw material, prolong the melting time of the raw material, and enhance the melting effect.

[0056] A heat-conducting ring 575 is provided on the side of the particle stirring blade 574 close to the first material guide tube 53, the surface of the heat-conducting ring 575 is fixedly connected to the inner wall of the outer shell 51, and the side of the heat-conducting ring 575 away from the first material guide tube 53 is set to an inner cone, and the inner spiral of the heat-conducting ring 575 is provided with a second heating wire 576, and the surface of the second heating wire 576 is fixedly connected to the inner side surface of the heat-conducting ring 575. The second heating wire 576 is started, and the second heating wire 576 melts the granular raw material in contact with it, and finally flows to the bottom of the outer shell 51. The heat-conducting ring 575 with an inner cone can ensure the complete flow of the molten raw material to avoid raw material residue, and the spiral second heating wire 576 can be set with a longer second heating wire 576 in a limited space to enhance the melting effect.

[0057] A melting stirring blade 577 is provided on the side of the heat conductive ring 575 away from the particle stirring blade 574. The melting stirring blade 577 is fixedly connected to the surface of the rotating shaft 573. The side of the melting stirring blade 577 away from the rotating shaft 573 is slidably connected to the conical bottom of the inner wall of the outer shell 51. The rotating shaft 573 drives the melting stirring blade 577 to rotate, stirs the molten raw material, avoids the molten raw material from solidifying, and thereby ensures that the molten raw material enters the first material guide tube 53.

[0058] When in use, the granular raw material is put into the upper barrel 52, the motor 571 is started, and the output end of the motor 571 drives the rotating shaft 573 to rotate, and drives the particle stirring blade 574 to rotate, so as to stir the granular raw material, and the second electric heating wire 576 is started, and the second electric heating wire 576 melts the granular raw material in contact with it, and finally flows to the bottom of the shell 51, and the rotating shaft 573 drives the melting stirring blade 577 to rotate, and stirs the molten raw material to prevent the molten raw material from solidifying, and the pump body 54 is started, and the pump body 54 drives the raw material to flow. The molten raw material is melted according to the flow. The raw material passes through the first material guide pipe 53, the pump body 54 and the second material guide pipe 55, and finally enters the material head 31. The raw material is injected into the material head 31, then contacts the semicircular plate 312, gradually climbs over the two semicircular plates 312 and enters the molding tube 33. Then, the wire core is first inserted from the cleaning tube 36, then enters the molding tube 33, and then enters the inner tube 34. The first heating wire 39 is started, and the first heating wire 39 generates heat to heat the molding tube 33. Finally, the molten raw material is located in the inner tube 34 outside the molding tube 33, and is formed into an outer sheath on the outside of the cable core.
