Description
Technical field
The utility model is related to plastic mould technical field, more particularly to a kind of plastic mould heater.
Background technology
Molding cycle during the plastic mould work of injection molding generally comprises matched moulds, injection, pressurize, cooling, die sinking, system
Mould is rapidly heated after the stages such as product taking-up, matched moulds, also mould is incubated in injection, packing stage, to increase
The mobility of melten gel, enables melten gel to fill each corner of mold cavity, it is ensured that product quality, can also shorten molding cycle, carry
High production rate.The conventional method of plastic mould heating is that heating oil duct is opened up in mould, using the deep fat circulated by heat
Amount is conducted to mould；The general injection unit each in oil temperature machine centralizedly supply, workshop of deep fat typically all can be in plastic mould
Deep fat oil inlet pipe on magnetic valve is equipped with to control fuel feeding, some pressure oil pumps that is equipped with increase the flow of deep fat in mould to strengthen
Heating effect.Because each injection unit work rhythm is inconsistent, sometimes to plastic mould while fuel feeding, or pressure oil pump are same
When work, deep fat house steward is evacuated, causes the deep fat short time insufficient, causes indivedual unit deep fats insufficient, influence modeling
The heating effect of sealing rubber die, to reach heating effect, will often increase the total supply of whole workshop deep fat, cause the wave of resource
Take, increase energy consumption.
Utility model content
The utility model overcomes the deficiencies in the prior art can be to the quick heating of plastic mould, energy-saving there is provided one kind
The plastic mould heater of consumption.
The utility model is achieved through the following technical solutions：
Oil is in charge of and gone out to a kind of plastic mould heater, including plastic mould, oil-feed house steward, fuel-displaced house steward, oil-feed
Pipe；Provided with heating oil duct in the plastic mould；The external oil temperature machine of oil-feed house steward and fuel-displaced house steward；It is described fuel-displaced to be in charge of
One end connects fuel-displaced house steward, and the other end connects the heating oil duct oil-out of plastic mould；Also include pressure oil pump, pressure oil tank,
Enter solenoid, overflow valve, overflow pipe, pressure sensor and controller；The pressure oil pump, pressure oil tank and enter solenoid
It is in charge of located at oil-feed；The oil inlet of the pressure oil pump is in charge of connection oil-feed house steward by oil-feed, and oil-out passes through oil-feed
It is in charge of the oil inlet of connection pressure oil tank；It is described enter solenoid one end by oil-feed be in charge of connection pressure oil tank it is fuel-displaced
Mouthful, the other end is in charge of the heating oil duct oil inlet of connection plastic mould by oil-feed；The oil inlet of the overflow valve passes through overflow
Pipe connects the oil-out of pressure oil pump, and the oil-out of overflow valve connects the oil inlet of pressure oil pump by overflow pipe；The pressure
Sensor is on pressure oil tank, inside its induction end connection pressure oil tank；The pressure oil pump, enter solenoid, pressure pass

During work, pressure sensor sends the pressure signal in pressure oil tank to controller at any time, when in pressure oil tank
Oil pressure less than setting lower threshold when, controller driving pressure oil pump work, into pressure oil tank, pump enters deep fat, works as pressure
When oil pressure in fuel tank reaches the upper limit threshold of setting, controller driving pressure oil pump is stopped；After plastic mould matched moulds,
Controller is opened into solenoid, and the deep fat in pressure oil tank is in charge of through oil-feed, enters heating oil of the solenoid to plastic mould
Inject deep fat in road, then through it is fuel-displaced be in charge of flow to fuel-displaced house steward, because oil pressure is higher in pressure oil tank, plastic mould heating oil duct
In deep fat flow velocity quickly, heat is conducted to plastic mould rapidly, plastic mould is rapidly heated；After packing stage terminates,
Controller is closed to be stopped to plastic mould fuel feeding into solenoid；When the oil pressure in pressure oil tank drops to the lower threshold of setting
When, controller driving pressure oil pump work, into pressure oil tank, pump enters deep fat until oil pressure reaches the upper limit threshold of setting, so
Circulation is repeatedly；Overflow valve is set to be shielded to plus-pressure fuel tank, when the oil pressure of the oil-out of pressure oil pump is more than overflow
During the overflow oil pressure of valve setting, overflow valve is opened to pressure oil pump oil inlet pressure release, is prevented oil pressure during failure and is exceeded pressure
Fuel tank bears pressure；Pressure oil tank also plays the deep fat supply of each injection unit in storage oil, adjustable car, when oil-feed is total
When the deep fat short time supply of pipe is not enough, still deep fat can be supplied from pressure oil tank to plastic mould, the deep fat of oil-feed house steward is normal
Deep fat can be stored in again during supply it is standby in pressure oil tank, therefore, when in workshop it is multiple injection unit simultaneously work when, do not increase
The aggregate supply of heating oil still ensures that each unit deep fat supply, can save energy province's consumption.
Further, the oil-feed of the pressure oil tank oil inlet is in charge of provided with inlet valve.It is easy to pressure oil tank to test and examine
Repair.
Further, the oil-feed of the pressure oil tank oil-out is in charge of provided with delivery valve.It is easy to pressure oil tank to test and examine
Repair.
Further, the pressure oil tank is provided with pressure gauge.The oil pressure condition of observable pressure oil tank.
Further, the oil-feed house steward, oil-feed are in charge of, are equipped with heat-insulation layer outside overflow pipe and pressure oil tank.Can be to entering
Oily house steward, oil-feed are in charge of, overflow pipe and pressure oil tank are incubated.
The beneficial effects of the utility model are：Using pressure oil pump and pressure oil tank, it can not only accelerate plastic mould heating
The deep fat flow velocity of oil duct, makes plastic mould be rapidly heated, and when multiple injection units work in workshop simultaneously, can also adjust each note
The deep fat supply of molding machine group, it is not necessary to the aggregate supply of increase reduction deep fat, can energy-saving consumption.
