Specific embodiment
Refering to attached drawing, the utility model exempts to cut cast gate bottle embryo blowing mould head, including gate orifice 1, material channel 2, small spray
Mouth 3, cast gate envelope material component, gate orifice 1 are connect with small 3 hole of nozzle, and cast gate envelope material component is arranged in small nozzle 3, and gate orifice 1 is logical
It crosses cast gate envelope materials and parts to communicate or close with small 3 hole of nozzle, material channel 2 includes material channel mouth A4 and material channel mouth B5, object
Material passway A4 is communicated with small nozzle 3, is also sealed material group by cast gate between material channel mouth B5 and small nozzle 3 and is communicated or close.
The utility model, can be by small nozzle 3 by increasing the hole communicated with material channel B being arranged in small nozzle 3
Interior material carries out circulation mixing, to ensure that the material homogeneous heating for entering gate orifice 1 from small 3 hole of nozzle, is not in
After material is cooling the phenomenon that internal superposition.
The cast gate envelope material component includes that envelope materials and parts A6, spring 7 and envelope materials and parts B8, envelope materials and parts A6 and envelope materials and parts B8 pass through bullet
Spring 7 is fixedly connected, and envelope materials and parts A6 and small 3 bore portion of nozzle coincide, envelope materials and parts B8 and material channel mouth B5 stapled section.
When work starts, the cylindrical end part of envelope materials and parts A6 enters small 3 hole of nozzle, and gate orifice 1 seals.When logical by material
When 2 injecting material liquid of road, powerful injection hydraulic action makes the spring 7 being fixedly connected with envelope materials and parts A6 in conical surface
Compression, envelope materials and parts A6 are moved down, and cylindrical body is detached from from small 3 hole of nozzle, and gate orifice 1 is opened, and feed liquid enters gate orifice 1,
Simultaneously there are also partial material liquid enter small nozzle 3 inside, when internal liquid reaches it is a certain amount of when, generated buoyancy adds spring
When 7 pressures are equal to material injection pressure, envelope materials and parts A6 is moved up, and cylindrical body enters small 3 hole of nozzle, and gate orifice 1 is closed, envelope material end face
It fits like a glove with gate orifice 1.Meanwhile spring 7 also drives envelope materials and parts B8 to move up, cylindrical body is detached from from material channel mouth B5,
