Besides, the adverse effect of the high-temperature molten metal on the performance of the heating device can be avoided, the service life of the heating device is further prolonged, the system temperature can be more accurately and finely adjusted, and the molten metal in the charging barrel has the optimal injection temperature.
Description
Technical field
The present invention relates to material injection device of die casting machine technical field, particularly relate to a kind of for die casting machine
The heating system of material injection device.
Background technology
Cold chamber die casting machine technology is by the molten metal of molten state Fast Filling mold cavity under high-voltage high-speed,
And make foundry goods under high pressure coagulation forming, it is the casting technique that current production efficiency is the highest.Foundry goods is carried out
Shoot material during die cast, need first alloy material to be heated into molten metal solutions, the most again
Metallic solution is directed in the barrel of material injection device, finally by piston by metallic solution penetrating from barrel
Material mouth carries out carrying molded in pushing to mould.But the molten metal of molten state is injected the barrel of material injection device
After, the temperature of metallic solution can reduce, and then impact shoots material；In order to make metallic solution at material injection device
Having suitable melt temperature in inner sleeve, during to ensure to shoot material, metallic solution has preferable mobility and relatively
Few air trapping, the barrel of material injection device is all heated by traditional handicraft.
As Chinese patent document CN201618837U discloses a kind of non-crystaline amorphous metal vacuum material injection device and bag
Including the die casting machine of this vacuum material injection device, its material injection device mainly includes barrel, and in described barrel
Move reciprocatingly penetrates splenium part, and the discharge outlet of this material injection device is provided with heater, and it adds hot charging
It is set to induction heating apparatus or resistor rod heater.The heater that this barrel is arranged near discharge outlet
Although the motlten metal injected in barrel can be maintained at uniform temperature, but owing to its heater is electricity
Heating rod or sensing heating, and barrel its temperature can be the highest injecting after molten metal bath, electrically heated rod or
Induction heating apparatus its heats under the high temperature conditions is the most unstable, it is difficult to ensure that the melted gold in barrel
Belong to liquid and there is suitable injection temperature, it addition, above-mentioned heater is shorter for service life under the high temperature conditions,
The operating cost causing this material injection device is higher.
And Japanese documentation JP2006346722A discloses a kind of material injection device, its heater is always
Extending at the gooseneck portion of barrel front end, in order to ensure safety, this barrel must have certain thickness,
And its heater is evenly provided on the outer wall of barrel, owing to this heating devices heat is to pass through barrel
Heat produced by heater could be passed to the metallic solution that it is internal, this mistake by the conduction of heat of wall thickness
In journey, the efficiency of heating surface is relatively low, and energy expenditure is relatively big, and, due to other portions of wall ratio in barrel gooseneck portion
Bulkhead thickness also wants big, and heat transfer efficiency is lower, and the molten metal in mould is injected in very difficult control after flowing through gooseneck portion
Actual temperature.
Summary of the invention
The technical problem to be solved in the present invention is the heating system on existing material injection device of die casting machine or adds
Thermal part the most easily breaks down, and the life-span is shorter, and heating-up temperature is unstable, it is not easy to regulation,
