Description
Technical field
It the utility model is related to Hot Runner System component technology field, more particularly to a kind of controllable temperature flow distribution plate.
Background technology
The passage of heat is to ensure that the plastics of runner and cast gate are kept molten by by the method for heating.Due to attached in runner
Near or center is equipped with heating rod and heating collar, and the whole runner for exporting to cast gate from injection molding machine nozzle makes all in the condition of high temperature
Plastics in runner keep melting.
In hot flow path, flow distribution plate plays very important effect, usually in a multi-cavity mold or multiple feed, single-point
Used when charging but material position biasing, flow distribution plate is used to the plastics of melting being transported to nozzle, and reaches mould eventually through each cast gate
Chamber.
Traditional flow distribution plate using heating collar when being heated, it may appear that heats non-uniform situation, the portion near heating collar
Position quickly reaches melting temperature, and then temperature is slightly lower at the position remote from heating collar, causes plastic molten melt incomplete, and existing shunting
The heating collar of plate is line mode of heating, causes the liquid firing rate near flow distribution plate inconsistent, in addition firing rate and temperature
Uncontrollable, the injection effect to product has a negative impact.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of controllable temperature flow distribution plate, the utility model
Heating process it is gentleer, heating evenly, and temperature-controllable.
A kind of controllable temperature flow distribution plate of the utility model, including a plate body, plate body is interior to be equipped with a cavity, is equipped with cavity more
A heating element, heating element connect temperature sensor, are also filled with conduction oil in cavity, plate body is equipped with least one stirring
Paddle, agitating paddle drive its rotation by driving device, and agitating paddle includes the pivoting leaf of agitating shaft, turntable and multiple variable-angles
Piece, rotating vane are extended outside with radial pattern from the center of turntable.
Further, it is equipped with one layer of polytetrafluoroethylene ethylene layer in cavity.
Further, aperture is offered on plate body, aperture is connected with cavity, and aperture internal thread is connected with plug.
Further, the quantity of agitating paddle is two.
Further, driving device is motor.
Further, temperature sensor is electrically connected controller.
Further, turntable is rotated with agitating shaft in a unitary manner.
Further, rotating vane is crescent.
Further, the number of rotating vane is 2-4.
According to the above aspect of the present invention, the utility model at least has the following advantages：
By setting multiple heating elements and temperature sensor in plate body, and heat conduction is filled with the cavity of plate body
Oil, when heating element heats, realizes by the heat transfer of conduction oil and plastics near flow distribution plate is evenly heated, and heats
Mode heats for face, and temperature sensor can realize accurate temperature controlling, prevent that heating-up temperature is too high or too low.
Conduction oil can regularly replace, and the polymeric layer stablized due to being equipped with one layer of property in cavity, the polymer surfaces
It is smooth, easy to the cleaning and replacement of internal conduction oil.
Agitating paddle can change the angle of rotating vane with the change of the rotating speed of driving device, have adjusted agitating paddle
Mixing area, overcomes the defects of traditional agitating paddle resistance is excessive, mixing area is fixed, while can be effectively by near deflector
Plastics mix, realization is evenly heated.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand the skill of the utility model
