Description
Technical field
The utility model relates to the field of mechanical technique of mfg. moulding die, is meant the indirect cooling and energy conserving device of a kind of mould temperature control machine especially.
Background technology
Known pressure casting method is that melted material is filled type under high pressure, high-speed condition in mould, and the casting method of cooled and solidified shaping under high pressure.And in the die casting production run of reality, the process engineer need take the serviceable life of mould into account, mould lost efficacy and mainly comprises three kinds of forms: heat fatigue be full of cracks damage was lost efficacy, and cracked inefficacy and corrosion were lost efficacy, and most mould failure modes belongs to heat fatigue be full of cracks inefficacy.The origin cause of formation that the mold hot fatigue cracking was lost efficacy is in the die casting production run, mould is subjected to the effect of rapid heat cycle repeatedly, the molded surface of mould and inner generation the thereof are out of shape, thereby involve mutually and round-robin thermal stress repeatedly occurs, finally cause institutional framework damage and forfeiture toughness, cause the generation of micro-crack; If micro-crack continues expansion, also may cause the material of fusion to clamp-on; Add mechanical stress repeatedly, can both make crackle quicken to enlarge.For this reason, in press casting procedure, on the one hand will be to fully preheating of mould when die casting is initial; On the other hand, the mould in the die casting production run must remain in certain operating temperature range, loses efficacy in order to avoid the heat fatigue be full of cracks occurs.
The mode temperature control that die casting machine in the market generally adopts water directly to cool off to mould can be subdivided into water-cooled and oil injection type again according to the difference of liquid coolant.When mould was carried out temperature control, for preventing that mould is subjected to rapid heat cycle and produces the be full of cracks inefficacy, liquid coolant needed just can remain on certain working temperature through the heating arrangement heating, liquid coolant through output pipe to mould, flow back to through return line, again through water pump pumps to heating arrangement, so repeatedly the circulation; Has bypass line between output pipe and the return line.But will export the mode inefficiency that liquid coolant and backflow liquid coolant are carried out heat interchange by bypass line in the prior art; And do not have cooling system is carried out the initiatively function of cooling; along with the die casting machine increase of working time; the temperature of cooling system constantly rises; when temperature exceeds limited range; the risk that mould lost efficacy has just improved greatly, therefore must stop processing, even shuts down cooling; cause the waste of yield-power, increased production cost and risk.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and the indirect cooling and energy conserving device of mould temperature control machine of a kind of reliability height, good cooling results is provided.
The utility model is realized by scheme by following technology, comprise the liquid heating chamber and be arranged on liquid heating chamber internal heat generation silk, the input end of liquid heating chamber connects supercharge pump, it is characterized in that: draw a by-pass pipe in the output terminal of liquid heating chamber, by-pass pipe connects a condenser and disposes condensation fan, and the output terminal of condenser is connected to the input end of supercharge pump.Condenser is an air-cooled condenser.The output terminal of condenser connects the input end that is connected to supercharge pump behind the retaining valve.By-pass pipe is provided with a solenoid valve.
Thereby advantage of the present utility model be by temperature sensor detect output temperature come the ON/OFF of control electromagnetic valve control the condenser condenses blower fan absorb cold in the air realized temperature from master regulation, guaranteed the constant of die casting temperature, increase the serviceable life of mould, improved yield-power; Reduced the risk that mould lost efficacy, i.e. cost has been saved in environmental protection again.
Description of drawings:
Fig. 1 is a water-cooled structure synoptic diagram of the present utility model;
Fig. 2 is an oil injection type structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described further, shown in Fig. 1 to 2, the utility model comprises liquid heating chamber 12 and is arranged on liquid heating chamber internal heat generation silk 121, the input end of liquid heating chamber 12 connects supercharge pump 15, draw a by-pass pipe 2 in the output terminal of liquid heating chamber 12, by-pass pipe 2 connects a condenser 22, and the output terminal of condenser 22 is connected to the input end of supercharge pump 15.Condenser 22 is an air-cooled condenser, and is simple in structure, conveniently installs and uses.The output terminal of condenser 22 connects the input end that is connected to supercharge pump 15 behind the retaining valve 23, and effectively controlling liquid flows to.Be provided with a solenoid valve 21 on by-pass pipe 2, solenoid valve 21 can reach automatically controlled requirement thus before condenser 22, realized robotization control.
When the indirect cooling and energy conserving device of mould temperature control machine was worked, heating wire 121 heat temperature raisings of liquid in liquid heating chamber 12 reached the working temperature that needs.Liquid in the temperature control system 1, flows back to through return line 13 after 14 from output pipe 11 to mould behind heat temperature raising, is pumped to liquid heating chamber 12 through supercharge pump 15 again.Fluid temperature in the temperature sensor automatic diagnosis temperature control system 1, when its temperature exceeds temperature-control range, the temperature control micro computer receives instruction and is converted to electric signal control electromagnetic valve 21, condenser 22 is opened, when the high-temp liquid in the liquid heating chamber 12 is defeated by mould 14, also deliver to condenser 22 from by-pass pipe 2, reduce the temperature of liquid by heat interchange, liquid after the cooling is through delivering to the input end of supercharge pump 15 behind the retaining valve 23, mix the liquid in the temperature control system 1, effectively reduce the fluid temperature in the temperature control system 1, so both can reach the heating-up temperature in the controlling liquid heating chamber 12, can reach the purpose of indirect cooling die 14 again, can realize the constant temperature effect fast, satisfy the commercial production requirement.When temperature reached preference temperature, solenoid valve 21, condenser 22 were closed, and quit work, and by-pass pipe 2 ends, and the thermophilic liquid in the liquid heating chamber 12 is defeated by mould 14, has guaranteed the constant of mold temperature, has increased the serviceable life of mould, has improved yield-power; Reduce the risk that mould lost efficacy, saved cost.
