Abstract

The invention provides a heating device and a plastifying device used for improving the cable inner end plastifying quality. The heating device comprises an annular structure formed by at least two circular arc heaters. The heaters are connected through hinges. At least one buckling component used for connection is arranged at the connecting positions between the heaters to form an opening-closing structure to be used for being arranged on a mold of the plastifying device in a sleeved mode. Each heater is provided with an electric insertion groove used for heating. The electric insertion grooves of the heaters are jointly connected to temperature feedback devices at the corresponding positions of the plastifying device. According to the heating device and the plastifying device, the two semi-circular-arc heaters are adopted, assembly and disassembly are conveniently achieved, and therefore the mold can be conveniently assembled, disassembled and adjusted; meanwhile, a temperature control system is connected with the temperature feedback device at the feeding section or the flange position, heating control and cooling control are accurately achieved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a heating device and plasticizing equipment for improving the plasticizing quality of the inner end of the cable. Background technique [0002] At present, when cables are extruded, due to different production requirements, molds of different specifications need to be used. In order to facilitate replacement, the molds used in existing equipment are exposed to the air, causing their temperature to drop, making the temperature of the mold lower, resulting in The plasticization of the inner surface of the cable is not good. Many manufacturers use a heater to heat the mold, but the thermocouple cannot be installed on the sheath of the mold or the mold, and the temperature cannot be controlled; After removing the device, reinstall it. Sometimes after the extrusion material is discharged, the mold and the sheath are bonded together. The heater for the sheath is difficult to i...
