Background technology
At present, the hot mouth of bull of the prior art many employings spring heater or cartridge heaters, add thermally labile, heater life is short, and structure is large, and take mould installing space large, production cost is high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one can make hot mouth main body heat transfer efficiency high, and heater is heated evenly, long service life, and intensity is good, good toughness, gross mass is little, and required heating power is also little, and energy consumption is lower, mold cavity is little, and mould strength is good, and die life is long; Meanwhile, conveniently guiding is installed, can prevents again mould from misplacing, scratch lining; Lining intensity is better, prevents sealing lining to be out of shape and leaks glue; Fuse heat conduction is rapid, and heat transfer efficiency is high, and runner hole is large simultaneously, and injection pressure is little, and plastic flow is fast, and shearing force is little, good product quality, and qualification rate is high, effectively reduces the hot mouth of bull of the embedded heating of production cost.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is a kind of hot mouth of bull of embedded heating, comprises sealing lining; Hot mouth main body is provided with in described sealing lining; Described hot mouth body outer wall is provided with groove; Heater is provided with in described groove; Described hot mouth body front end is provided with alloy fuse; Described sealing lining is provided with heater line outlet;
Preferably, described sealing lining is stepped; Described sealing bush inside and the sealing of hot mouth main body, outside and mould sealing.
Preferably, described alloy fuse is integral type structure.
Preferably, described alloy fuse and hot mouth main body are threaded connection.
Preferably, described hot mouth body rear face is provided with lifting screw hole.
The invention has the beneficial effects as follows: the hot mouth of bull of a kind of embedded heating of the present invention, hot mouth main body embeds heater structure compact, hot mouth main body heat transfer efficiency can be made high, heater is heated evenly, long service life, intensity is good, good toughness, gross mass is little, required heating power is also little, and energy consumption is lower, and mold cavity is little, mould strength is good, and die life is long; Meanwhile, sealing lining is stepped conveniently can install guiding, can prevent again mould from misplacing, scratch lining, and back segment does greatly simultaneously, and lining intensity is better, and when preventing superelevation injection pressure, glue is leaked in the distortion of sealing lining; And alloy fuse is integral type structure, fuse heat conduction is rapid, and heat transfer efficiency is high, and runner hole is large simultaneously, and injection pressure is little, and plastic flow is fast, and shearing force is little, and plastics are not easy degraded, good product quality, and qualification rate is high, effectively reduces client's production cost.
