Effectively heat can be avoided to scatter and disappear compared to existing technologies, plastic melt will not solidify in machine barrel, in mould into
Type effect is more preferable, and rubber heat-insulation layer is also flexible, and phenol formaldehyde foam layer effectively can be wrapped up, and fitting is closer and solid
It is good to determine effect；One end of annular incubation cavity towards head is provided with opening and the opening detachable connection of annular incubation cavity has
Setting for one ring end plate can pass through annular in order to the installation of phenol formaldehyde foam layer inside annular incubation cavity and rubber heat-insulation layer
The opening of incubation cavity is inserted in annular incubation cavity, and carries out closing fixation by ring end plate；Can so as to reach the utility model
To avoid heat from being lost in machine barrel, the more preferable purpose of mould molding effect.
The utility model is further arranged to：Dormant bolt is equipped between the phenol formaldehyde foam layer and rubber heat-insulation layer.
By using above-mentioned technical proposal, the fixed effect between phenol formaldehyde foam layer and rubber heat-insulation layer can be further enhanced
Fruit, avoid shifting, while dormant bolt can avoid that machine tube inner wall is caused to damage and be easy to strong phenol formaldehyde foam layer and rubber
Glue heat-insulation layer is installed in annular incubation cavity.
The utility model is further arranged to：The rubber heat-insulation layer is polyurethane insulation coating.
By using above-mentioned technical proposal, compressive property can be strengthened on the basis of heat insulation effect is ensured, extend and use
Life-span.
The utility model is further arranged to：The consistency of thickness and phenol formaldehyde foam of the phenol formaldehyde foam layer and rubber heat-insulation layer
The cumulative volume of layer and rubber heat-insulation layer is adapted with the volume of annular incubation cavity.
By using above-mentioned technical proposal, phenol formaldehyde foam layer and rubber heat-insulation layer is set to fill and riddle annular incubation cavity
It is interior, it is completely closed, heat insulation effect is further enhanced, while avoid making phenol formaldehyde foam layer and rubber heat-insulation layer because frame is run
Shift or shake.
