Abstract
The invention discloses a composite metal mould. The mould comprises a metal body with a gate, wherein the gate of the metal body comprises a straight gate and a horizontal gate; and high-temperature resistant layers of which the thermal conductivity is lower than that of the metal body cover the inner walls of the straight gate and the horizontal gate. Through the mode, the service life of the mould can be prolonged, product quality and production efficiency can be improved, energy is saved, and cost is reduced.
Description
Technical field
The present invention relates to casting field, particularly relate to a kind of composition metal mould.
Background technology
Mainly be to adopt sand casting in China's iron casting production at present.The sand mold casting is to adopt the method for sand moulding to carry out the molten iron pouring moulding to obtain foundry goods, and the shortcoming that adopts this kind method is because the cooling velocity of ironcasting in sand mold is slow, and cast member forms the graphite form of a definite form only, the general easy thick graphite form that forms.The graphite form tiny like need generally will adopt metal type dies, and reason is because the metal type dies cooling velocity is fast, is prone to form tiny graphite form.In the ironcasting permanent mold casting, generally adopt the method for iron-based die casting, development in recent years is to the golden mold casting method of useful copper alloy die.
In the above casting method, its medium sand casting labour intensity is big, noise is big, and the dust of generation, antiquated sand, waste gas is contaminated environment and influence the healthy of workman not only, and the while casting quality is low, machining allowance is big, and stock utilization is low, efficient is low, energy consumption is big.And the ferrous metals type in use produces very big thermal stress because of its huge thermograde, not only shortens the service life of metal type dies greatly, and influences casting quality, and production efficiency is not high yet simultaneously.The relevant work of the domestic in recent years ironcasting copper alloy type casting of conducting a research makes much progress, but still it is big to exist in the casting process temperature loss; Have to improve pouring temperature, problem such as die life is long, its reason be since in the metallic mould gate and mould metal body be an integral body; Processed by same metal material, pyroconductivity is high, after molten iron pours into gate; The inwall of gate has absorbed a large amount of heats in the molten iron very soon, and very fast conduction gives metallic mould whole, and be cooled water and air of heat diffuses away; Thereby make the molten iron temperature of real injection die cavity low, therefore at this moment have to improve the molten iron temperature at place, sprue gate, waste energy than what expect; Cause the raw material scaling loss to increase simultaneously, because metal die is prone to heat radiation, not only the temperature of die cavity is inconsistent with expection during cast; The temperature control at sprue gate is also relatively more difficult, and the gate passage is longer, and molten iron forms bigger difference in height when die cavity arrives gate; Thereby the impact potential energy of snare is formed on the running channel bottom, thereby cause the metallic mould life-span to descend.Cause bigger waste, increased production cost.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of composition metal mould, can improve service life and the product quality and the production efficiency of mould, and energy savings reduces cost.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of composition metal mould is provided; Comprise the metal body that is provided with gate; The gate of said metal body comprises straight gate and horizontal gate, and the inwall of said straight gate and horizontal gate is coated with the little high-temperature-resistant layer of thermal conductivity ratio metal body.
Preferably, said high-temperature-resistant layer forms composite construction through the inwall of inlaying, spraying or be applied in straight gate and the horizontal gate of metal body.
More excellent is that said high-temperature-resistant layer is a ceramic layer.
More excellent is that said metal body is iron body, ferroalloy body, copper body or copper alloy body.
The invention has the beneficial effects as follows: a kind of composition metal mould of the present invention is produced under the little prerequisite of the original production model transformation of maintenance production line; Being coated with the little high-temperature-resistant layer of thermal conductivity ratio metal body at the inwall of straight gate and horizontal gate is ceramic layer; Energy savings greatly; Prolong die life more than 3 times, reduce cost.
