Abstract
The invention discloses a cooling method for a die-casting mould. The method comprises the following steps: step 1, repeatedly spraying and blowing compressed air towards a forming part of the die-casting mould; step 2, introducing a cooling liquid into a mould core of the die-casting mould to carry out cooling; ad step 3, recycling and cooling the cooling liquid, and repeatedly introducing the recycled and cooled cooling liquid into the mould core of the die-casting mould. The cooling method for the die-casting mould overcomes the problem that the service life of a formed die-cast apparatus is shortened due to the fact that a cooling step in the prior cannot be grasped well, and realizes cooling the die-casting mould with a prolonged service life.
Description
Technical field
The present invention relates to automobile manufacturing field, particularly, relate to a kind of cooling means of compression mod.
Background technology
The forming method of compression mod is at high pressure, high-speed condition, by molten alloy lower charging type, and the method for the hot investment casting of under high pressure cooled and solidified shaping.Compression mod is in compression casting forming technology, the metal die used in order to shaped casting.
In the prior art, for compression mod, cooling is a very important step, if cooling step is grasped bad, may reduce shaping after service life of die casting device, so designing a kind of cooling means that can extend the compression mod treating die casting device service life becomes a kind of problem needing solution badly.
Summary of the invention
The object of this invention is to provide a kind of cooling means of compression mod, the cooling means of this compression mod overcomes cooling step of the prior art and grasps bad, can reduce shaping after the problem in service life of die casting device, achieve the cooling of the compression mod increased the service life.
To achieve these goals, the invention provides a kind of cooling means of compression mod, the method comprises:
Step 1, jets repeatedly by the moulding section of compressed air towards compression mod;
Step 2, cools in core cooling fluid being passed into compression mod;
Step 3, reclaims cooling fluid and after lowering the temperature, repeats to pass in the core of compression mod.
Preferably, in step 2, cool in core cooling fluid being passed into compression mod with the flow velocity of 1-2m/s.
Preferably, in step 3, cooling fluid reclaimed and after cooling to 20-25 DEG C, repeat to pass in the core of compression mod.
Preferably, in step 2, described cooling fluid comprises the water of 50% and the vinyl alcohol of 50%.
Preferably, in step 2, described cooling fluid comprises the water of 75% and the ethylene glycol of 25%.
By in above-mentioned embodiment, by above-mentioned embodiment, the cooling means of compression mod of the present invention is by air-cooled and water-cooled twice cooling, realize the cooling of the core of compression mod, repeatedly jetted by the moulding section to compression mod, can brushing and coating in mould be blown even and the gas that coating volatilizes is dispersed in acceleration, reduce the pore that die casting causes because of gas that coating volatilizes, high by water cooling cooling effectiveness, good cooling results, is conducive to shortening the shaping cycle.
Other features and advantages of the present invention are described in detail in detailed description of the invention part subsequently.
Detailed description of the invention
Below the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, it is interior and outer that " inside and outside " refers on concrete profile.It is far away and near that " far away, near " refers to relative to certain parts.
The invention provides a kind of cooling means of compression mod, the method comprises:
Step 1, jets repeatedly by the moulding section of compressed air towards compression mod;
Step 2, cools in core cooling fluid being passed into compression mod;
Step 3, reclaims cooling fluid and after lowering the temperature, repeats to pass in the core of compression mod.
By in above-mentioned embodiment, by above-mentioned embodiment, the cooling means of compression mod of the present invention is by air-cooled and water-cooled twice cooling, realize the cooling of the core of compression mod, repeatedly jetted by the moulding section to compression mod, can brushing and coating in mould be blown even and the gas that coating volatilizes is dispersed in acceleration, reduce the pore that die casting causes because of gas that coating volatilizes, high by water cooling cooling effectiveness, good cooling results, is conducive to shortening the shaping cycle.
By the advantage of comprehensive air-cooled and water-cooled, achieve the cooling for compression mod.
In a kind of detailed description of the invention of the present invention, in step 2, cool in core cooling fluid being passed into compression mod with the flow velocity of 1-2m/s.By the Flow-rate adjustment cooling effectiveness of controlled cooling model liquid, thus reach the requirement of Die Casting technique.
In this kind of embodiment, in step 3, cooling fluid reclaimed and after cooling to 20-25 DEG C, repeat to pass in the core of compression mod.When temperature is 20-25 DEG C, reuse the cooling that can realize compression mod.
In this kind of embodiment, in step 2, described cooling fluid comprises the water of 50% and the vinyl alcohol of 50%.Expand effective cooling scope, be applicable to multiple metal crimp foundry goods.
In this kind of embodiment, in step 2, described cooling fluid comprises the water of 75% and the ethylene glycol of 25%.Such cooling fluid is reused effective, can repeatedly continuously service time long, save production cost.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
