Description
Technical field
Plastic cement injection technique field is the utility model is related to, is concretely related to one kind and speaks out of turn core side gate type hot mouth.
Background technology
Injection moulding (injection) is to make thermoplasticity or duroplastic moulding materials material first homogenous plasticized in heating cylinder, then
A kind of molding method in the die cavity of Guan Bi mould is pushed through by plunger or mobile screw.Injection moulding is suitable for almost all
Thermoplastic.In recent years, injection moulding is also successfully used to be molded some thermosetting plasticses.Injection molding short molding cycle
(several seconds to a few minutes), shaped article quality can be by several grams to tens kilograms, can one-pass molding complex contour, accurate size, band
There is the moulded work of metal or non-metallic insert.Therefore, this method is adaptable, and production efficiency is high.The injector of injection moulding
It is divided into two major class of ram injector and screw-type injection machine, is made of injecting systems, clamping system and mold three parts.
Hot flow path uses in injection mold, the heating group plastic pellet of thawing being injected into the cavity of mould
Part system.Hot runner mould is by heating, when each shaping by the running channel of traditional type mould or shree plates mold and runner
A kind of brand-new construction of runner and running channel need not be taken out, hot flow path is to ensure runner and cast gate by the method for heating
Plastics are kept molten by.Due near runner or center is equipped with heating rod and heating collar, exporting to and pouring from injection molding machine nozzle
The whole runner of mouth makes the plastics in runner keep melting, runner need not be generally opened after shutdown and is taken all in the condition of high temperature
Heating flow channel is only needed when going out condensate, then starting shooting to required temperature.Hot Runner System is generally by hot nozzle, flow distribution plate, temperature control
A few part compositions such as case and annex.
Currently used hot runner hot nozzle can not meet vertically into the requirement of glue, therefore work as needs from product side into glue
When just can not accurately be injected, while common side gate generally by hot nozzle first by time of its injection into becoming a mandarin
Road, then plastic material enter mold cavity along runner, be so likely to have plastic material remain in runner formed it is useless
Material, can cause the waste of raw material；Hot nozzle current at the same time is that a sprue connects a mouth core, the size of hot nozzle
It is larger, it can not meet the batch mould production of the small spacing type of multi-cavity.
Utility model content
Therefore speak out of turn core side gate type hot mouth the utility model proposes one kind, for solve current hot mouth cannot meet from
Product side causes waste material to produce into glue, and the problem of can not meet the batch mould production of the small spacing type of multi-cavity.
What the technical solution of the utility model was realized in：One kind is spoken out of turn core side gate type hot mouth, including hot mouth body,
Primary heater is cased with outside hot mouth body surface, sprue is equipped with hot mouth body, further includes flow distribution plate body, flow distribution plate upper casing

Road one end is communicated with sprue, and the other end is communicated with runner, and mouth core, mouth core are equipped with the end of runner described in each
Perpendicular to the side of flow distribution plate body；The flow distribution plate upper casing is arranged on flow distribution plate body upper surface, and flow distribution plate upper casing is equipped with
Heating tank and temperature-sensitive string holes, heating tank is interior to be equipped with secondary heater, is equipped with temperature-sensitive string holes and is used to detect plastic material temperature
Temp.-sensing wire；The flow distribution plate lower casing is arranged on flow distribution plate body lower surface.
During specific works, hot mouth is placed on the caster of mould, each mouth core is respectively positioned in mold cavity at this time,
And mouth core, perpendicular to the side of flow distribution plate body, mouth core is vertical with mold cavity at this time, and the plastic material then melted enters master
Runner, then flows into transition runner, and runner is finally entered after transition runner, by mouth core by the plastics material in runner
Material direct injection enters mold cavity, is then cooled and shaped, and mouth core is located on flow distribution plate body side, therefore mouth core can be perpendicular to
Injection point, so that from product side into glue, while flow distribution plate upper casing is equipped with heating tank and temperature-sensitive string holes, and the is equipped with heating tank
Two heaters, temperature-sensitive string holes is interior to be equipped with the temp.-sensing wire for being used for detecting plastic material temperature, and temp.-sensing wire can experience plastic material and exist
The intrinsic true temperature of flow distribution plate, prevents temperature is too low from material frozen can be made not project, and temperature is excessive to cause material
It is excessively heated to cause material to be carbonized or turn to be yellow, so as to improve the quality of product.
Further, the spacing between the adjacent mouth core is equal.Mouth core is evenly distributed on flow distribution plate body, easy to mouth
The installation of core, while avoid two adjacent mouth core spacing from crossing recent photo and ring work.
Further, the primary heater and secondary heater are heating wire.Heating wire is taken conveniently, and utilizes electricity
Heated filament heating can ensure homogeneous heating, keep heating work to stablize and carry out.
Further, the contact position of the hot mouth body and flow distribution plate upper casing is equipped with titanium alloy heat-insulating cushion block.
The thermal conductivity factor of titanium alloy is λ=15.24W/ (m.K), therefore thermal conductivity factor is smaller, is shunted when plastic material enters
Heat can be reduced during road to scatter and disappear, and avoided plastic material from producing condensation inside runner, influenced the injection of plastic material.
Further, the flow distribution plate body is equipped with the first lock screw, and the first lock screw passes through flow distribution plate upper casing
With titanium alloy heat-insulating cushion block, flow distribution plate upper casing is equipped with the second lock screw, and the second lock screw passes through titanium alloy heat-insulating cushion block, point
Flowing plate lower casing is connected with the 3rd lock screw.
Flow distribution plate body, flow distribution plate upper casing, flow distribution plate lower casing and titanium alloy thermal insulation board are using being threadedly coupled, and connection is more
Reliably, it is more firm.
Further, the flow distribution plate upper casing is equipped with c-type positioning pin.When mounted can be accurate easy to flow distribution plate upper casing
Positioning, avoid flow distribution plate upper casing installation it is wrong.
By above disclosure, the beneficial effects of the utility model are：By setting some points in the utility model
Runner, so as to ensure that hot mouth can realize the application of the small spacing of mould multi-cavity, and mouth core is perpendicular to the side of flow distribution plate body,
And mouth core is placed in inside mold cavity, when from product side into glue, just mouth core is vertical with injection point, so as to fulfill vertically into
Glue.
