Abstract
The utility model discloses an injection member of an injection-moulder, which comprises a nozzle, a sprayer and a machine cylinder, wherein the sprayer is arranged at the front end of the machine cylinder; the nozzle is arranged at the front end of the sprayer; the machine cylinder is provided with a first heating device; the nozzle is provided with a second heating device; the first heating device is a heating wire intertwined on the outer wall of the machine cylinder; a metal sleeve ring is arranged outside the heating wire; the injection member of the injection-moulder has the advantages that: the heating wire is directly intertwined on the outer wall of the machine cylinder; the metal sleeve ring is arranged outside the heating wire; the heating wire can directly transmit the heat to the machine cylinder; and less heat is emitted under the protection of the metal sleeve ring. The injection member greatly increases the heat utilization rate during heating.
Description
Technical field
The utility model relates to a kind of injection machine, especially relates to a kind of injection machine injection member.
Background technology
Traditional injection moulding machine injection member comprises nozzle, shower nozzle and machine barrel; Be provided with screw rod in the machine barrel; Shower nozzle is arranged on the machine barrel front end, and nozzle is arranged on the shower nozzle front end, and heater comprises ceramic heat cover and thermocouple on the injection member; The ceramic heat circle is wrapped on shower nozzle and the machine barrel, and the thermocouple segmentation is inserted in the machine barrel.Injection machine injection member heater has played conclusive effect to the quality of injecting products, and the injecting products that produce must be controlled the temperature of machine barrel, shower nozzle and nozzle well.
There is following problem in heater on the injection member of said structure: 1. the ceramic heat circle is wrapped in the surface of machine barrel, and heating collar exposes in the middle of air, and this causes the unstability of barrel zone temperature.2. because ceramic across one deck between ceramic heat circle and the machine barrel, heat transfer effect is bad, causes machine barrel heat energy utilization rate not high.
Summary of the invention
The utility model technical problem to be solved provides a kind of injection machine injection member that improves the heat energy utilization rate.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of injection machine injection member, comprise nozzle, shower nozzle and machine barrel, and described shower nozzle is arranged on the machine barrel front end; Described nozzle is arranged on the shower nozzle front end; Described machine barrel is provided with first heater, and described nozzle is provided with second heater, and described first heater is a heater strip; Described heater strip is wrapped on the described machine barrel outer wall, and described heater strip is outside equipped with metal ferrules.
Be connected with the thermocouple device on the described heater strip.
Described second heater is a turn formula heater, and described turn formula heaters set is located on the described shower nozzle.
Described metal ferrules is outside equipped with protective cover, and described protective jacket is fixed on the described machine barrel through support column.
Described metal ferrules is made up of the first half lassos and the second half lassos, and described the first half lassos and the second half lassos interfix with screw.Adopt the mode of two and half lassos, make that the dismounting of metal ferrules is more convenient.
Compared with prior art, the utility model has the advantages that heater strip directly is wrapped on the machine barrel outer wall, heater strip is outside equipped with metal ferrules, and heater strip can be directly the heat transferred machine barrel, and under the protection of metal ferrules, heat is less outwards to be distributed.
InjectionParts are in the middle of heating process, and the heat energy utilization rate improves greatly.
Thermocouple directly detects the temperature of heater strip, and sends to computer through control circuit, can control the temperature of heater strip better.
Turn formula heater directly is set on the shower nozzle, and heats is fine.
Protective cover can be protected heating wire and metal ferrules.
