The present invention provides a kind of injection forming mold, has the die cavity 1 for plastic cooling and shaping, Fig. 1 mentions for the present invention
The cooling system of the injection forming mold supplied.
Referring to Fig. 1, the cooling system includes: cooling chamber 2, cooling equipment 3, water inlet water route 4, is discharged water route 5, is multiple
Two-position three way magnetic valve 6, multiple range sensors 12 and controller 11.The cooling chamber 2 is set in a manner of wrapping die cavity periphery
It is placed in mold.Cooling equipment 3 can be circulating cooling machine and be also possible to cooling water pump, and the cooling equipment 3 includes for water end (W.E.)
And backwater end, so that cooling water enters the cooling chamber 2 after the outflow for water end (W.E.), then flow out, returns to from the cooling chamber 2
The cooling equipment 3 is handled.The cooling equipment 3 is connected to for the water inlet water route 4, Yi Jilian of water end (W.E.) and the cooling chamber 2
Lead to the water outlet water route 5 of 3 backwater end of cooling equipment and the cooling chamber 2, is set to outside the cooling chamber 2.Outside the cooling chamber 2
Multiple two-position three way magnetic valves 6 are additionally provided with, there is the first port 7 for being connected to the water inlet water route 4, the connection water outlet water circuit
5 second port 8 and the third port 9 of the connection cooling chamber 2, each two-position three way magnetic valve 6 have described first
The first working condition and the first port 7 that port 7 is connected to the second port 8 be connected to the third port 8
Two working conditions.The multiple range sensor 12 is set to 1 inner wall of die cavity and the multiple 6 phase of two-position three way magnetic valve
Corresponding position, for detecting the distance between 1 inner wall of die cavity and plastic.The range sensor 12 can be optics away from
From one of sensor, infrared distance sensor, ultrasonic distance sensor.Controller 11, be electrically connected it is the multiple away from
From sensor 12 and the multiple two-position three way magnetic valve 6, for being controlled according to the testing result of the range sensor 12
Each two-position three way magnetic valve 6 switches between the first working condition and second working condition.
The cooling system of injection mold provided by the invention starts institute during raw material enters the die cavity 1 cooling
Cooling equipment 3 is stated, provides cooling water for the cooling chamber 2 circulation.The cooling equipment 3 include for water end (W.E.) and backwater end so that
Cooling water enters the cooling chamber 2 after the outflow for water end (W.E.), then flows out from the cooling chamber 2, returns to the cooling equipment 3
It is handled.Multiple two-position three way magnetic valves 6 are additionally provided with outside the cooling chamber 2, when the two-position three way magnetic valve 6 is in the
When one working condition, the cooling water flows through the cooling chamber 2 by original route, when the two-position three way magnetic valve 6 is in second
When working condition, the unheated cooling water flows into the cooling chamber 2 from the first port 8 of the two-position three way magnetic valve 6,
Reduce the local temperature of corresponding 6 installation site of two-position three way magnetic valve of the cooling chamber 2, thus reduce herein with water inlet water
The temperature difference between road 4, so that the cooling of plastic is more uniform in the die cavity 1, is unlikely to deform.And the two-position three-way electromagnetic
The working condition of valve 6, which can according to need, to be controlled, so that the cooling system does not need to carry out complicated water route design, knot
Structure is simpler.
Further, plastic has the characteristic expanded with heat and contract with cold, during cooling and shaping the plastic can gradually with institute
The inner wall separation of die cavity is stated, and isolated distance is bigger, illustrates that the size reduced herein is more, in this way, the controller 11
The multiple two-position three way magnetic valve can be controlled according to the distance detected, in the big place control described two of size reduction
The first working condition of entrance of position-3-way solenoid valve 6 reduces flow, in described two three small of place control of size reduction
Three-way electromagnetic valve 6 enters the second working condition or increases flow, so as to realize plastic cooling and shaping process described in equal control
In deflection everywhere.
Further, referring to Fig. 2, the depth of the arrangement of the multiple two-position three way magnetic valve 6 and the die cavity 1 is in pair
It should be arranged.For example, the place deeper in 1 depth of die cavity, plastic radiates more in type-approval process in die cavity 1, it is corresponding this
The two-position three way magnetic valve 6 of more, more dense arrangement is arranged in place.And the place shallower in 1 depth of die cavity, the interior modeling of die cavity 1
Part radiates less in type-approval process, corresponding that less, more sparse two-position three way magnetic valve 6 is arranged herein.In this way, described two
The arrangement of three-way magnetic valve 6 is correspondingly arranged with the heat dissipation during the plastic cooling and shaping, can more effectively meet cooling
It needs.
Further, Fig. 2 and 3 are please referred to, the work of the two-position three way magnetic valve 6 is automatically controlled by the controller 11
Make state.Temperature is separately installed at the water inlet water route 4 of the cooling chamber and the third port 9 of each two position three-way valve 6
Sensor 10, the controller 11 are electrically connected with the temperature sensor 10, measure to obtain into water temperature at the water inlet water route 4
Spend TA, the valve temperature measured at one of them described two position three-way valve 6 is Tn, as the inflow temperature TAWith the valve
Door temperature TnBetween difference DELTA TA-nWhen greater than first threshold Δ T, the controller 11 controls described one of them two
Three-way magnetic valve 6 is the second working condition by the first active state.It so, it is possible the process in the plastic cooling and shaping
The Temperature Distribution of cooling water in the middle control cooling chamber 2, so that the cooling of the plastic is more uniform.It is preferred that described first
Threshold value Δ T is 0.8 to 2 degree Celsius, and the best first threshold Δ T is 1 degree Celsius.Optimal cooling effect can be reached.
Further, when the two position three-way valve is in the second working condition, the controller 11 can adjust described
The aperture of multiple two position three-way valves 6, to adjust intensity of cooling herein as needed.
The water inlet water route 7 of the cooling chamber is discharged at 6 third ports 9 of water route 8 and each two position three-way valve and distinguishes
Temperature sensor 10 is installed, the controller 11 is electrically connected with the temperature sensor 10, measures at the water inlet water route 4
Obtain inflow temperature TA, measure to obtain leaving water temperature T at the water outlet path 5B, measure at one of them described two position three-way valve 6
The valve temperature arrived is TnIf the inflow temperature TAWith the valve temperature TnBetween difference be Δ TA-n, the water inlet temperature
Spend TAWith the leaving water temperature TBBetween difference be Δ TA-B, the controller 10 is according to the Δ TA-nWith Δ TA-BBetween ratio
Value determines the aperture of one of two position three-way valve 6.It is preferred that as Δ TA-n/ΔTA-BWhen≤30%, the two position three-way valve
Aperture be 100%；As 30% < Δ TA-n/ΔTA-BWhen≤70%, the aperture of the two position three-way valve is 60%；As Δ TA-n/
ΔTA-BWhen > 70%, the aperture of the two position three-way valve is 30%.It so, it is possible the reality according to cooling water described at valve
Temperature Distribution controls the aperture of the two position three-way valve 6, so that distribution of the cooling water in the cooling chamber 2 is more
Uniformly.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant technical fields, similarly
It is included within the scope of the present invention.
