Description

Hot flow path sequential injection controller

Technical field:

The utility model relates to the injection mold technical field, refers in particular to sequential injection controller in a kind of hot runner mould.

Background technology:

Along with China plastic article is injected the flourish of processing, the hot flow path The Application of Technology is increasingly extensive.As the hot flow path technology of having used more than 30 year in the world, be the new stage of injection molding technology development, compared many benefits with the cold runner of routine, comprising: save material; Shorten molding cycle; Improve products surface quality and mechanical property; Needn't promptly can use the hole irrigation mouth with shree plates mold; Can be economically with the single goods of side gate moulding; Improve automaticity; Available needle valve cast gate control cast gate is freeze-up; The moulding uniform quality of multi-cavity mold; Improve injection-molded item surface aesthetic degree or the like.

Injection moulding process at large-scale mould all can use two kinds of technology: hot flow path and order injection technology, and to produce qualified plastic.In the production of now, this two partly all is to overlap controller independently by two to finish separately control function.Wherein the hot flow path controller mainly is the temperature control part, and what it mainly adopted is that independent charactron shows that each warm area is controlled by an independent control unit.So just produce a problem, if the group number of hot runner mould is numerous, being used to install temperature control electronic box partly promptly can be very huge.For the control partly of order injection, its most time relay that adopts is finished, and the problem of Chan Shenging is exactly like this: relay wiring is more loaded down with trivial details.When mold exchange more, also to manually set all parameters again, mistake so just appears easily.In addition, because this two parts controller is independent separately running, also cannot realize the requirement of safety interlock.

The utility model content:

Technical problem to be solved in the utility model overcomes the shortcoming of present product exactly, a kind of hot runner mould sequential injection controller is provided, the utility model mainly is that hot flow path control function and order injection function are incorporated within the cover control system, realizes this two kinds of functions simultaneously by single controller.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this controller comprises: a man-machine interaction management interface, this man-machine interaction management interface is realized user and machinery compartment communication, reception and registration and reception information, and it comprises a display and signal keyboard with key supporting; One control module, this control module have the cpu controller that is used for being responsible for control, computing at least; One can be with the thermocouple input interface of machine actual temperature signal input; One can be with the stroke and the pressure detecting interface of mechanical injection pressure, the input of mold cavity pressure signal; One can be with the switching value input/output interface of mechanical interlocked information and control heating and the input of valve signal; One is used to control the simulation output interface of hydraulic pump.

The utility model is from simplifying user's operation, develop a kind of brand-new controller, making it have hot flow path temperature control function and order injection control function.Slave controller make the operator when mold exchange more, as long as after a relevant plug connected, can be produced corresponding die parameters taking-up.Use liquid crystal display man-machine interface operator to make more effective monitoring and adjustment to the function of temperature control and order injection.And realize by same set of system because of two kinds of functions, can realize security interlock function etc.In addition, but parameter has memory function, promptly the mould of in the past producing can be kept in the controller, when producing like products afterwards, only need call relevant parameter and can finish the parameter setting.

The utlity model has the parameter memory function, can be kept at controller unit inside to the die parameters of producing in the past, when the subsequent production like products, the parameter that only need call associated storage just can be finished parameter and set.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

The specific embodiment:

See Fig. 1,2, one man-machine interaction management interfaces 1, this man-machine interaction management interface is realized user and machinery compartment communication, reception and registration and reception information, and it comprises: a display 11 and signal keyboard with key supporting 12; One control module 2, this control have the cpu controller that is used for being responsible for control, computing at least.

One thermocouple input interface 3 inputs to controller by this interface 3 with the machine actual temperature signal.

One stroke and pressure detecting interface 4 are used for injection moulding stroke, pressure, the input of mold cavity pressure signal with the injection machine injection, for example adopt screw injection molding machine, and the travel parameters of screw rod inputs in the control module 2 by this interface.

One switching value input/output interface 5 is used for the input with injection machine and mechanical interlocked information of hot flow path and control heating valve gate signal;

One simulation output interface 6, this interface is used for the control of hydraulic pump 61.

The characteristic that the utility model has been used the powerful program performance of industrial control unit (ICU) and hardware is capable of being combined and expand has realized temperature control function and the control of order injection are incorporated in the same controller.Increased stroke and pressure detecting interface 4 simultaneously, made the time control of the switch of order injection valve by unit, index position or pressure control have improved the repeatability accurately of action.

The utility model adopts technique scheme, has following advantage:

1, can realize the function of temperature control and order injection simultaneously by a bench control system.

2, use the resolution ratio of high-precision temperature control input module temperature to reach 0.1 degree C control accuracy at+/-0.5 degree C.

3, use high-precision position input module and high speed host computer host can guarantee that the reaction time is within 5 milliseconds.

4, adjustment time of having shortened greatly behind the mold exchange more of the utility model dropped in 5 minutes by 20-30 minute.

5, simplify wiring, all devices is connected directly to the utility model by interface and gets final product.

Slave controller make the operator when mold exchange more, as long as after a relevant plug connected, can be produced corresponding die parameters taking-up.Use liquid crystal display man-machine interface operator to make more effective monitoring and adjustment to the function of temperature control and order injection.And realize by same set of system because of two kinds of functions, can realize security interlock function etc.In addition, but parameter has memory function, promptly the mould of in the past producing can be kept in the controller, when producing like products afterwards, only need call relevant parameter and can finish the parameter setting.

Certainly, the above only is example of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
