Specific embodiment
Embodiment:
The present embodiment is set for die heater, but does not limit use and die heater.
Die heater is called mould temperature controller, initially applies the temperature control industry in injection mold.Later with mechanical row
The development and application of industry is more and more extensive, and present die heater generally divides water temperature machine, oil temperature machine, and temperature-controlled precision can achieve ± 0.1 DEG C.
It is each that die heater is widely used in plastic molding, die casting, rubber tyre, roller, chemical reaction kettle, bonding, mixing etc.
Each industry of row.It broadly says, is Temperature-controlled appliance, the temperature control comprising heating and freezing two aspects.
Die heater also has very large space in the utilization of Die Casting Industry, especially in magnesium alloy, the manufacture of aluminium alloy, no
It is unstable that average or unsuitable mold temperature will lead to casting dimension, ejects casting deformation in process of production, generates hot pressing
The defects of power, glutinous mould, surface indentation, internal shrinkage and thermal.Production cycle is also had an impact, such as filling time, cooling time
And spray time all generates unstable parameter.The service life of mold also can lead to expensive steel because of the impact by supercooling overheat
Material generates hot tearing, accelerates its aging.
In the factory of modernization, in response to the competition in market, manpower is saved, quality is improved, reduces the management tactics of cost
It is very urgent, the use of die heater, mold preheating time can be made to reduce, finished surface increased quality and can be fully automated
Production.Improving die life is the necessary means to increase productivity.
For temperature controller in the necessary condition that the utilization of other industry is then that equipment is constituted, call is also different.In PVC sheet
It is oil heater in roller temperature control, is temperature control device in squeezing out machine equipment, temperature control system is cried in rubber internal mixing machine equipment
System is temperature controlling machine, a substantially process for being first rapidly heated, followed by keeping the temperature in these equipment.And in rubber equipment
Also need to execute the process of a cooling down after heating for a long time.
Die heater is by water tank, heating and cooling system, dynamic transfer system, tank level control system and temperature sensor, note
The devices such as entrance composition.
Under normal conditions, the pump in dynamic transfer system makes hot fluid from the water tank equipped with internal heater and cooler
Mold is reached, then returns to water tank from mold;The temperature of temperature sensor measurement hot fluid simultaneously transfers data to control section
Controller;Controller adjusts the temperature of hot fluid, to adjust the temperature of mold indirectly.If die heater is in production, mold
Temperature be more than controller setting value, controller will open solenoid valve connect water inlet pipe, until the temperature of hot-fluid liquid, i.e. mould
The temperature of tool returns to setting value.If mold temperature is lower than setting value, controller will open heater.
But referring to Fig. 2, show pump-type type selecting table, die heater at this stage is coping with different occasions, needs corresponding set
The mechanical pump for setting different model has reached required fluid flow rate.
The present embodiment is to pass through the driving motor of stepless time adjustment motor substitution transmission for the pump control technology in die heater
As the driving portion of mechanical pump, so that mechanical pump is corresponded to different occasions and use, in different occasions to the control of pump to reach
The fluid of corresponding flow velocity is accurately provided, to guarantee the working performance of die heater, specifically, it shows that a stepless speed regulation formula is more
Occasion fluid control systems, controller that is being arranged including mechanical pump and corresponding mechanical pump and being used cooperatively with mechanical pump are constituted,
Mechanical pump includes the pump chamber portion of driving portion and the portion's of being driven driving, and driving portion is made of stepless time adjustment motor；
More occasion fluid offers are carried out to include the following steps:
1) the fluid flow rate Va provided needed for being inputted by controller；
2) fluid flow rate Va of the controller based on required required offer controls driving portion by controller with corresponding revolving speed Vb
Rotation, the offer of the corresponding flow for carrying out corresponding flow velocity.
Mechanical pump is made of magnetic force driving pump, including driving portion 1, the magnetic drive part 2 that is connected to driving portion 1, is connected to
The bracket 3 of driving portion 1, the pump chamber module 4 being set on bracket 3, the impeller 5 being rotatably set in pump chamber module 4, impeller 5
It is connected to drive shaft 6, drive shaft 6 is connected with magnetic drive driven member 7 that is corresponding with magnetic drive part 2 and being used cooperatively；
Magnetic drive driven member is driven to rotate by magnetic drive part, the driving portion and follower relative separation of magnetic force driving pump,
I.e. pump chamber is to be independently arranged, and is not required to that the sealing system for guaranteeing pump chamber leakproofness is additionally arranged, while guaranteeing the close of pump chamber again
Sealing property, when then guaranteeing magnetic drive pump work, stable fluid driving that can be long-term.
The driving magnetic drive driven member rotation of magnetic drive part is crossed, the driving portion and follower of magnetic force driving pump are opposite to be divided
From that is, pump chamber is to be independently arranged, and the driving force of driving portion directly passes through magnetic force and is transferred to impeller, a kind of low energy of magnetic drive
The transmitting of loss compares mechanical shaft seal formula sealing structure, can reduce the energy loss of 8%-10%, and fluid control is more accurate.
