Abstract
The utility model discloses an automatic control device for preheating of a cold mold of a core manufacturing machine. The automatic control device comprises a PLC (Programmable Logic Controller), an input and display device and a heating device, and is characterized in that the heating device comprises an air heater and an air blow pipeline, wherein the air blow pipeline is connected to an air blow hood of the core manufacturing machine; the PLC is electrically connected with a main circuit of the core manufacturing machine, a core manufacturing machine operation control circuit and a heating device control circuit. According to the automatic control device, the core manufacturing machine is controlled by the PLC, so that a core box and the air blow hood are kept in a sealed state, and the core box is preheated by the heating device, thereby realizing the automatic control over the preheating of the cold mold of the core manufacturing machine, improving the production efficiency, reducing the operation waste rate, improving the stability and the sand mold quality and reducing the tail gas production.
Description
Technical field
The utility model relates to a kind of control of metal casting machine, is specifically related to a kind of automaton that core making machine is carried out to cold mould preheating.
Background technology
Sand casting is to become the casting method of casting mold with the molding sand consolidation, is widely used in the production of cast iron and steel-casting.Wherein, the manufacture of core is one important operation in sand casting.Core is generally to prepare realization by core making machine by core box.In prior art, cold-box process does not need heating usually, adopts as triethylamine as curing agent.But temperature is influential to sand core strength.For example, " casting " magazine 11 phases in 1994, in " impact on the cold-box process sand core strength of roughing sand temperature and air humidity " literary composition, analyzed the impact of roughing sand temperature, thought, " for example, in order to guarantee the core steady quality; the roughing sand temperature should be controlled to certain limit; 21～27 ℃ ..., when catalysis system can only make catalyst atomization and can not gasify, the roughing sand temperature should be controlled at higher than 27 ℃ ".
Inventor's discovery, not only the roughing sand temperature is influential to the core quality, and the temperature of core box is also influential.Under cold machine state, the core box temperature is low, directly carries out the coremaking operation, easily cause core loose, solidify complete, tail gas is many, not environmental protection; In addition, easily cause core loose, make made core produce a large amount of useless cores, cause production cost to improve.
Therefore, provide a kind of device of controlling the cold mould preheating of core making machine, have great significance to addressing the above problem.
Summary of the invention
Goal of the invention of the present utility model is to provide the automaton of the cold mould preheating of a kind of core making machine, core making machine is controlled automatically to the problem of work influence product quality under the cold machine state of core making machine in the solution prior art.
To achieve the above object of the invention, the technical solution adopted in the utility model is: the automaton of the cold mould preheating of a kind of core making machine, comprise PLC controller, input and display unit, heater, described heater comprises air heater, air blowing pipeline, described air blowing pipeline is connected to the air blowing shield of core making machine, and described PLC controller is electrically connected to core making machine main circuit, core making machine running control circuit and heater control circuit.
In technique scheme, set the cold mould preheating mode of core making machine by input and display unit, the PLC controller is carried out corresponding control program, mutual by with core making machine main circuit and core making machine running control circuit, control appliance makes core box and air blowing shield in sealing state, control heater by the heater control circuit and start heating blow out air, the hot-air after the air heater heating in heater enters in core box through air blowing pipeline, air blowing shield, and core box is preheated.Stop preheating mode after reaching setting-up time, by the PLC controller, control and enter normal production status.
In technique scheme, described air heater is provided with temperature control equipment.
Described input and display unit are HMI equipment.
Further technical scheme, described PLC controller forms the MPI network through MPI interface and core making machine main circuit, core making machine running control circuit and heater control circuit.Can realize better the communication between each circuit thus.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model is controlled core making machine by the PLC controller, makes core box and air blowing shield in sealing state, by heater, core box is carried out to preheating, thereby has realized that the cold mould preheating of core making machine controls automatically.
2. the utility model can be communicated with work with the core making machine control circuit, realizes start one key operation, easy to use, and the problem that can avoid operator's violation operation to bring.
3. carry out cold mould preheating by the core box to core making machine, can enhance productivity, reduce operation waste rate, improve stability and sand-mould quality, reduce tail gas and produce.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment mono-: shown in Figure 1, the automaton of the cold mould preheating of a kind of core making machine, comprise PLC controller, input and display unit, heater, described input and display unit are HMI equipment, and described PLC controller forms the MPI network through MPI interface and core making machine main circuit, core making machine running control circuit and heater control circuit.
Shown in accompanying drawing 2, in the present embodiment, described heater comprises air heater 1, air blowing pipeline 2, and described air blowing pipeline 2 is connected to the air inlet 4 of core making machine air blowing shield 3, under preheat mode, to the inner die cavity of core box 5, blows and heats.
Control method is to set the cold mould preheating mode of core making machine and preheating cycle by HMI equipment, and the PLC controller is carried out corresponding control program, and a key starts, while automatically moving and prompt facility at hanker in advance/equipment in idle loop.When setting cycle reaches, equipment is out of service, waits for that operating personnel confirm.
