[0001] COOLER FOR DIECASTING [0002]

The present invention relates to a die-casting mold cooling cooler, and more particularly, to an improved die-casting mold cooling cooler that is mounted on a mold and allows cooling water to flow in and out to cool the die.

Generally, a die casting process for molding a casting mold having the same shape as a mold by injecting a melt into a mold is performed by designing and manufacturing a mold, injecting molten metal into the mold at a high pressure, holding the casting mold under a predetermined condition, demolding the mold, The process of controlling the temperature of the mold in this process has a great influence on the completeness of the casting.

That is, when the shape of the mold is complicated or large, the temperature distribution of each part of the mold can not be uniformly maintained, thereby causing problems such as the casting being deformed in the taking-out process, resulting in mass production of defective products.

A device for cooling the mold by supplying cooling water to each part of the die-casting mold by circulating the cooling water is developed and provided, and a schematic configuration thereof will be described below.

8 to 9, the mold cooling apparatus to which the prior art is applied has a plug 3 having an outlet pipe 2 coupled to the front end thereof, and an inlet pipe 4 is provided in the inside diameter of the outlet pipe 2, So as to engage with the plug 3. The cooling water flowing into the mold 5 through the inlet pipe 4 and the heat exchanged with the mold 5 are formed in the plug 3 through grooves for discharging the cooling water to the outside through the outlet pipe 2 And an inlet port 10 and an outlet port 11 for introducing and discharging cooling water are formed in the head 8. A hexagonal head 12 for engaging and disassembling the mold 5 is formed on the side of the plug 3 and the plug 3 and the head 8 are fastened by means of intermittent means 13 such as a bolt .

In the above-described conventional apparatus for cooling a mold, a head and a plug, which are the main constituents, are molded so as to maintain a tightly coupled state through a first precision machining using a metal, particularly stainless steel excellent in corrosion resistance, · Forms are completed through secondary finishing processes such as cutting and polishing of external shapes, and they are combined with each other using interrupting means.

However, the above-described precision machining and post-machining are not only difficult to work with metals having poor processability, such as stainless steel, but also cause mixing or leakage of cooling water even with a single error, In addition, since the stainless steel is relatively expensive, the economical burden due to the cost increase is increased.

In the mold cooling apparatus of the related art, although the intermittent means is used for coupling between the head and the plug, the intermittent means is easily separated and lost during the coupling and separation between the two structures, .

Accordingly, the present invention has been made to solve the above-mentioned problems,

A first coupling hole 123 to which the inlet port 121 is coupled and a second coupling hole 124 to which the outlet port 122 is coupled are formed on one side of the head 120;

The inner diameter of the head 120 is formed with an airtight member 122 so as to block the inflow water flowing from the first coupling hole 123 to the inlet port 111 and the outlet water phase flowing from the outlet port 112 to the second coupling hole 124, (126) through which the gasket (125) is inserted;

A first detachable hole 127 for coupling and separating the plug 110 and the head 120 accommodated in the inner diameter of the head 120 is formed at the rear end of the head 120;

The first detachable hole 127 is coupled with the head 120 and the plug 110 through the fastening means 130. The fastening means 130 includes a second detachable hole 130 formed at the rear end of the plug 110, (D1) smaller than the inner diameter D1 of the first attachment / detachment hole 127 and having a length (T1) longer than the thickness T1 of the rear end of the head 120 And the threaded portion 131 protrudes outward from the rear end of the head 120 so as to hold the engagement portion 132 on the first detachable hole 127 And a fastening portion 133;

The head 120 is formed by extrusion processing using aluminum so that the entire outer shape is formed into a finished state to be coupled with the plug 110, thereby shortening the manufacturing process of the cooler 100 itself, It is possible to achieve the object of providing a mold cooling cooler having excellent water retention.

Since the present invention is constructed so that the entire external shape of the head is formed into a finished state by using aluminum, which is superior in workability compared to a conventional apparatus for cooling a mold, which is manufactured by precision machining of stainless steel, and is connected to the plug, It is advantageous to improve the price competitiveness by reducing cost and cost because the manufacturing process can be greatly shortened because only the inner processing is required without further post processing.

Especially, the airtightness is ensured only by the simplified configuration, and the excellent performance is realized. Furthermore, the coupling and separation between the plug and the head are easy, and the maintenance is excellent.
