Technical field
A kind of die casting temperature controlling instruments belongs to the technical field of processing equipment of material, particularly the temperature control device of die casting.
Background technology
In recent years, magnesium alloy since its to have density low, only be 2/3 of aluminium, 1/4 of iron and steel, specific strength and specific stiffness height, the heat-conductivity conducting performance is good, have good damping shock absorption and capability of electromagnetic shielding, and be easy to advantages such as machine-shaping, be subjected to paying attention to widely in scientific and technological circle and industrial circle.The twentieth century end, along with the reduction of cost and the breakthrough one by one of technical bottleneck, magnesium alloy is just progressively applied in industries such as automobile, electronics, communications and is come.
Magnesium alloy pressure-casting is the mode that mainly shapes of current magnesium-alloy material production, because magnesium metal special physicochemical character, control ratio aluminium alloy, kirsite that magnesium alloy pressure-casting is produced die-casting technological parameter want strict, magnesium alloy pressure-casting production must be controlled the die casting temperature, it is stabilized in a certain temperature range, all adopts special-purpose mould temperature controlling instruments to control mold temperature usually.
Conventional mould temperature controlling instruments adopts water as the temperature control medium, because the boiling point of water restriction, its maximum operation (service) temperature generally is no more than 150 ℃, and mold temperature generally will remain on more than 250 ℃ during magnesium alloy pressure-casting, so it can not satisfy the technological requirement of magnesium alloy pressure-casting.Minority mould temperature controlling instruments adopts conduction oil as the temperature control medium, operating temperature can satisfy the requirement of magnesium alloy pressure-casting, but the huge and complex structure of its machine itself, working service inconvenience, and temperature control precision is low, and production on-site environment is abominable in addition, and the die casting temperature can not be effectively controlled, cause the magnesium alloy die casting quality to be subjected to very big influence, percent defective raises.
The utility model content
The purpose of this utility model provide a kind of simple in structure, easy to use, satisfy the mould temperature controlling instruments that mold heated in the press casting procedure and cooling require, be specially adapted to magnesium alloy pressure-casting, by using this equipment can improve the surface and the inherent quality of magnesium alloy die casting, reduce the percent defective that die casting is produced, prolong the service life of compression mod simultaneously.
Feature of the present utility model is: the oil inlet pipe (6) that contain the flowline (9) that is connected successively with the oil-out of mould (7), filter (10), heater (5), cooler (4), oil pump (2), is connected with the oil-in of mould (7), and the inlet of described oil pump (2) is connected by expansion tube (14) with the fuel tank (12) that is positioned at its top; Another inlet of described cooler (4) connects a magnetic valve (3) that is used for logical cooling water, on described oil inlet pipe (9), flowline (6) thermal resistance (11) is installed respectively; The signal output part of described two thermal resistances (11) links to each other with the signal input part of a microcomputerized controller (17) respectively, and the control end of described oil pump (2), magnetic valve (3), heater (5) connects the control signal output of microcomputerized controller (17) respectively.
A level sensing switch (13) that is used to monitor oil level is housed in the fuel tank (12), and its signal output part connects the signal input part of described microcomputerized controller (17).In fuel tank (12) top a blast pipe (15) is housed, its other end connects the inlet of described oil pump (2).In fuel tank (12) top an overflow pipe (16) is housed.Between described flowline (9) and oil inlet pipe (6), a by-pass flow valve (8) is housed.Described microcomputerized controller (17) is Siemens S7-200 type PLC.
Experiment showed, that the utility model can effectively control the variations in temperature of mould in the press casting procedure, reached its intended purposes.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is made up of fuel tank, heater, cooler, magnetic valve, oil pump, filter, check valve, microcomputerized controller, oil pipe and casing.Fuel tank 12 places the top of casing 18 inside, and oil pump 2 places the below of casing 18 inside; Fuel tank 12 belows link to each other by expansion tube 14 and oil pump 2 inlets, but oil free wxpansion enters fuel tank 12 when guaranteeing heat-conducting oil heating, and while expansion tube 14 can play initial oil-feed pump 2 fuel feeding effects; Fuel tank 12 tops are connected with oil pump 2 inlets by blast pipe 15, discharge the gas that heat-conducting oil heating produces, and make system stable; An overflow pipe 16 is installed in fuel tank 12 tops; Oil return pipe 9 one termination moulds 7, the other end are connected to oil pump 2 inlets by filter 10, heater 5, cooler 4 successively; Oil pump 2 outlets pick out oil pipe 6 and pass to mould 7, and heater and cooler are commercially available; Connect a check valve 8 between flowline 6 and the oil return pipe 9, play the bypass effect; Cooling water feeds cooler 4 by magnetic valve 3; Fuel tank 12 a built-in level sensing switch 13 monitoring oil levels; On flowline 6 and the oil return pipe 9 thermal resistance 1,11 is housed respectively; Microcomputerized controller 17 is housed on casing 18, and this microcomputerized controller is Siemens S7-200 type PLC.
