Description
Technical field
The invention belongs to die casting equipment field, more particularly to a kind of die casting mold point cold.
Background technology
Die casting temperature is too high to cause mould to be cracked too early, the movable device serious wear such as slide block thimble, casting matter
Amount problem is such as：Hot tearing, prying, surface pores, foaming, overlap, carbon distribution.Die casting temperature is too low to cause casting quality problem
Such as：Fill not full, excess shrinkage, cold line.The temperature of die casting is the important technological parameter of die casting, influences casting quality,
Production efficiency is influenceed, casting cost is influenceed.
There is time timer on the existing die casting cooling device used, all pipeline only one of which water-main roads, own
Water flowing time only one of which can set, do not reach constant temperature effect.The mould cooling used at present, mainly gives core drop
Temperature, hydraulic pressure pressure size is non-adjustable, when certain water lines in mould inside because the problems such as cooling water has impurity or fouling, makes
Blocked into water lines, in the inside of mould or the inside of water lines, it is not easy to be found, so that product is unstable, fraction defective
When very high, it can just go to check water lines, cause many defective products, waste manpower and materials very.
The content of the invention
It is an object of the invention to provide a kind of die casting mold point cold, it is intended to solves existing die casting cooling device
Constant temperature effect is not reached, hydraulic pressure pressure is non-adjustable, water lines are blocked or the ND problem of leak.
The present invention is achieved in that a kind of die casting mold point cold includes filter, water tank, constant voltage water pump, flow and passed
Sensor, timer, ball valve；Described filter, water tank, constant voltage water pump are sequentially connected with, and described constant voltage water pump delivery port is connected to
Multi-way water pipe road, is provided with flow sensor and timer, constant pressure water tank is realized by Frequency Converter Control on per water lines all the way
The constant pressure of hydraulic pressure, adjustable, every water lines end mounting ball valve all the way.
Further, when described die casting mold point cold sets water flowing start delay time and blown according to die casting machine signal
Between, realize that cooling water quickly enters mould and the heat of liquation is decomposed when liquation enters mold cavity, when mould die sinking
Casting departs from, and cooling water is closed.
Further, described die casting mold point cold sets the time of the water flowing of every water lines, realizes every water lines
Corresponding region mould temperature is controllable.
Further, described die casting mold point cold is different according to the quantity of mould cooling tube, and the number of pipeline is opened in selection
Amount；Have a timer in every water lines, it is necessary to number road water pipe, turn on corresponding timer.
Further, every water lines water flowing flow can be shown in real time；Flow sensor is equipped with every water lines, when
When having water flowing, just have flow and show in real time.
Further, when flow of the actual flow below or above setting, real-time monitoring equipment can automatic alarm, setting water
The superelevation limit value and ultralow limit value of flow, compare the two numerical value and present real-time traffic in real time, when actual flow is less than ultralow
Limit value or just alarm during higher than superelevation limit value；Because pressure is constant, water lines are constant, that is, the resistance of water pipe does not change
In the case of flow and most should also be certain, so around this principle, to test its flow.
Further, 0-8 kilograms of the hydraulic pressure of described constant voltage water pump delivery port is adjustable, according to water flowing time different constant voltage water pumps
The water-carrying capacity of delivery port can reach 120 liters/min -800 liters/min；It is adapted to the cold of various moulds in order to reach a cold
But, so the pressure of constant voltage water pump water outlet saliva can reconcile (0-8 kilograms) pressure, the pipeline according to required for mould is different,
The total flow of constant voltage water pump can also be selected.
The present invention is provided with multi-way water pipe road, can be set per the water flowing time of water lines all the way, realize every water lines institute
Corresponding region mould temperature is controllable；Constant voltage water pump realizes the constant pressure, adjustable of hydraulic pressure by Frequency Converter Control；Every water lines water flowing
Flow can be shown in real time, when flow of the actual flow below or above setting, and system meeting automatic alarm predicts water pipe in advance
Whether block or leak, to reduce the generation of defective products, reduce production cost.
Brief description of the drawings
Fig. 1 is the structural representation of die casting mold point cold provided in an embodiment of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, the present invention is achieved in that a kind of die casting mold point cold includes filter, water tank, constant pressure water
Pump, flow sensor, timer, ball valve；Described filter, water tank, constant voltage water pump are sequentially connected with, and described constant voltage water pump goes out
The mouth of a river is connected to multi-way water pipe road, is provided with flow sensor and timer on per water lines all the way, constant pressure water tank is by frequency converter
The constant pressure of hydraulic pressure, adjustable, every water lines end mounting ball valve all the way are realized in control.
