Description
Technical Field
The utility model relates to the technical field of release agent spraying, in particular to a variable-temperature spraying system of a mold release agent.
Background
The aluminum alloy high-pressure casting and the spraying of the release agent are important process links, and the functions are as follows: (1) The die-casting spraying function is to provide an effective isolation protection layer between the die-casting alloy and the die, prevent molten metal from directly flushing the surfaces of the cavity and the core, and improve the working condition of the die; the heat conductivity of the die is reduced, the fluidity of the molten metal is maintained, the filling smoothness of the molten metal is ensured, and the formability of the metal is improved; the high-temperature lubrication performance is kept good, friction between the die casting and a forming part of the die, particularly a core is reduced, the die casting is convenient to push out, smooth demolding of the die casting is facilitated, the service life of the die is prolonged, and the surface quality of the die casting is improved; preventing sticking to the mold. (2) The die-casting spraying also has the function of cleaning a die cavity, can not produce scale on the surface of the die-casting die cavity, and has no corrosion effect on the die-casting die and the die-casting piece. (3) protecting the die: the temperature of the die can be reduced by spraying the coating, the die temperature is reduced by heat dissipation, the die damage caused by high temperature is avoided, the service life of the die is prolonged, and the abrasion to the punch, the ejector rod and other parts can be effectively reduced.
When the production is started, the temperature of the die does not reach the production process requirement, so that a thermal module is required to be produced to raise the temperature of the die, and the thermal module is scrapped. Because of the product demoulding requirement, the same amount of mould release agent is sprayed before each thermal module is produced, so that the temperature of the mould is reduced, and the efficiency of improving the temperature of the mould is reduced. The mold temperature at the early stage has not reached a steady state, and the temperature at the local position may be lower. In the normal production stage, besides cooling by using internal cooling water, the mold release agent spraying also has the effect of cooling. Because the metal thickness of each part of the mold surface is different, the heat absorbed by the metal at the thicker position is more, the local high temperature is reduced to a certain extent by increasing the spraying amount and the spraying time of the release agent in the production beat, but the local high temperature is difficult to be reduced to an ideal range, and the defects of aluminum sticking, product pull injury and the like are caused on the mold surface. In winter, the temperature of the spraying liquid is lower (below 10 ℃) and is unchanged, and the thermal stress on the surface of the die can be easily caused by a larger temperature difference.
Therefore, there is a need to solve the problems of damage to the die body or quality defect of the die-casting product caused by excessive difference between the mold release agent and the die temperature at different production stages and different environmental temperatures.
