Abstract
The invention relates to a die for improving the mechanical property of a magnesium alloy casting. The die comprises a movable die and a fixed die, wherein the movable die and the fixed die are assembled to form a die cavity; a heat preservation liquid passageway is formed in the die cavity; and a liquid inlet port and a liquid outlet port which correspond to an inlet and an outlet of the heat preservation liquid passageway are formed in the movable die. By the die for improving the mechanical property of the magnesium alloy casting, the heat of the die can be effectively kept; according to a technical requirement, the temperature of the die is controlled within a range of 250 +/- 25 DEG C; the mechanical property of a product is improved; and the yield and the production efficiency are effectively improved.
Description
Technical field
The present invention relates to technical field of mold, especially a kind of mould that improves the Mg alloy castings mechanical performance.
Background technology
Magnesium alloy is to add the alloy that other elements form take magnesium as base.Be characterized in: density little (about the 1.8g/cm3 magnesium alloy), specific strength is high, and elastic modelling quantity is large, good heat dissipation, shock absorbing is good, and the load-carrying ability that withstands shocks is larger than aluminium alloy, and the corrosive nature of anti-organic matter and alkali is good.Its process and corrosion and mechanical property have many characteristics: rapid heat dissipation, quality are light, good rigidly, have certain corrosion resistance and dimensional stability, shock resistance, wear-resisting, fade performance good and be easy to recovery; Also have in addition high heat conduction and electric conductivity, nonmagnetic, shielding good and nontoxic characteristics.Magnesium alloy is widely used in portable apparatus and the automobile industry, reaches light-weighted purpose.
If mold temperature was excessively low when magnesium alloy was poured into a mould in casting process, can reduce the mechanical performance of foundry goods, thereby affect the quality of product, do not reach instructions for use.If mold temperature is too high during cast, it is slow to cause again falling the foundry goods temperature, affects production efficient.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of mould that improves the Mg alloy castings mechanical performance is provided, can effectively control mold temperature, guarantee casting quality.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mould that improves the Mg alloy castings mechanical performance, comprise dynamic model and cover half, dynamic model and cover half matched moulds form die cavity, be provided with insulation liquid path in the described die cavity, offer the feed liquor interface corresponding with being incubated liquid lane entrance and outlet on the dynamic model and go out liquid interface.
Insulation liquid in the described insulation liquid path is conduction oil.
The invention has the beneficial effects as follows that the mould of raising Mg alloy castings mechanical performance of the present invention can effectively keep the temperature of mould, by 250 ± 25 ℃ of technological requirement control mold temperatures, improve the mechanical performance of product, Effective Raise yield rate and production efficiency.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiment of the present invention's mould of improving the Mg alloy castings mechanical performance;
Fig. 2 is the side-looking partial sectional view of the preferred embodiment of the present invention's mould of improving the Mg alloy castings mechanical performance.
Among the figure: 1, dynamic model, 2, cover half, 3, die cavity, 4, insulation liquid path, 5. the feed liquor interface 6. goes out liquid interface.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, the mould of raising Mg alloy castings mechanical performance of the present invention, comprise dynamic model 1 and cover half 2, dynamic model 1 and cover half 2 matched moulds form die cavity 3, be provided with insulation liquid path 4 in the described die cavity 3, offer the feed liquor interface 5 corresponding with being incubated 4 imports of liquid path and outlet on the dynamic model 1 and go out liquid interface 6.Insulation liquid in the described insulation liquid path 4 is conduction oil.
The temperature of the temperature control mould by the control conduction oil by 250 ± 25 ℃ of technological requirement mold temperatures, has avoided cold mould to reduce the situation of product mechanical performance, improves finished product rate and quality.Also be conducive to magnesium alloy at cooling stage and cool off fast, enhance productivity.
Claims (2)
