Description
Technical field
The present invention relates to a kind of pair of concentration mold releasing agent spraying device and method, belong to releasing agent spraying technology field.
Background technology
In extrusion process, spraying link is one of deciding factor affecting casting quality, and mold surface temperature directly affects releasing agent spraying effect.
The Water-cooling circulating of mould inside, for making mould reduce temperature, need to dispel the heat by die surface and external heat exchange; During spraying releasing agent, the heat of die surface is taken away in the water vapor in releasing agent, makes the active principle in releasing agent be attached to die surface formation coating, and has avoided moisture entrapment in mould, to produce bubble.
According to verification experimental verification; releasing agent is approximately 2:1 for the time ratio of cooling die and formation protective finish; be that in releasing agent spraying process, approximately to have time of 2/3 be for cooling die; for domestic mould; less and cooling effect is poor by the design of cooling water channel in the inner, the time for cooling die in releasing agent spraying process even can reach 3/4, therefore; in order to make die surface form good coating, first need to rely on a large amount of use releasing agents as early as possible mold temperature to be lowered.
In whole spraying process, adopt all the time the releasing agent of single concentration to carry out cooling to mould; when reaching releasing agent reaction temperature, just start really to bring into play releasing agent and as protective layer, prevent the effect of sticking to mould; this by using a large amount of high concentration releasing agents to carry out cooling mode to mould, will certainly cause the use waste of releasing agent.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of pair of concentration mold releasing agent spraying device and method, solves the excessive problem that causes using waste of Die Casting Industry releasing agent use amount.
To achieve these goals, the technical solution used in the present invention is: a kind of pair of concentration mold releasing agent spraying device, comprise spray robot, also comprise high concentration releasing agent proportioning machine and the mechanical, electrical magnetic transfer valve of two releasing agent proportionings of low concentration releasing agent proportioning machine and releasing agent shower nozzle, high concentration releasing agent proportioning machine and low concentration releasing agent proportioning machine are connected to the first delivery pump and are connected with electromagnetic switching valve and releasing agent shower nozzle successively with after the second delivery pump, and spray robot is controlled high concentration proportioning machine, the mechanical, electrical magnetic transfer valve of low concentration proportioning and releasing agent shower nozzle.
A concentration releasing agent spraying method, spraying step is:
(1) proportioning goes out the releasing agent of a high concentration and a low concentration, and the releasing agent of two kinds of variable concentrations is put into respectively to high concentration releasing agent proportioning machine and low concentration releasing agent proportioning machine;
(2) when mold surface temperature is higher than 280 °, spray robot provides signal, and electromagnetic switching valve is switched to low concentration releasing agent pipeline, and releasing agent shower nozzle output low concentration releasing agent sprays cooling;
(3) when mold surface temperature arrives 150-280 °, spray robot provides signal, electromagnetic switching valve is switched to the releasing agent pipeline of high concentration, and releasing agent shower nozzle output high concentration releasing agent sprays die surface;
(4) use gases at high pressure that the unnecessary releasing agent of die surface is blown down.
Preferably, in described low concentration releasing agent, the proportioning of releasing agent and water is 1:300-1:400.
Preferably, in described low concentration releasing agent, the proportioning of releasing agent and water is 1:300.
Preferably, in described high concentration releasing agent, the proportioning of releasing agent and water is 1:80-1:200.
180-250 ° of C of best surface temperature of coating formation, at this temperature, the evaporating capacity of water is moderate, and the coating of formation is evenly smooth; Under optimum temperature, the time of adhering to of coating is about 0.5-1 second, and excessive spraying extends spray time, and may wash away coating.
The releasing agent of the high and low two kinds of variable concentrations of proportioning of the present invention is put into respectively two releasing agent proportioning machines, the releasing agent of low concentration is mainly used in mould cooling, make mold surface temperature reach the reaction temperature of releasing agent the best, the releasing agent of high concentration is used for making die surface to form coating and prevents sticking to mould, the present invention has significantly reduced the use amount of releasing agent in the situation that guaranteeing coating quality, the consumption that can save releasing agent reaches 25%---and 30%, reduced production cost.
