Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a production mold for aluminum alloy die castings. Background Art

[0002] Aluminum alloy die castings refer to equipment components made of pure aluminum or aluminum alloys by casting. Generally, a sand mold or metal mold is used to pour heated liquid aluminum or aluminum alloy into the mold cavity, and the obtained aluminum parts or aluminum alloy parts of various shapes and sizes are usually called aluminum die castings.

[0003] After searching, the patent number CN202022087653.1 discloses a production mold for aluminum alloy die-castings. This solution is achieved by arranging a cooling sleeve on the outer side of the lower die base and a spraying mechanism on the inner wall of the cooling sleeve. The lower die base is cooled by the spraying mechanism. This solution has the following shortcomings: First, the water used by the spraying mechanism is room temperature water, which cannot achieve effective cooling of the module, and cannot achieve the recycling and reuse of the water used in the spraying mechanism. Secondly, this solution only cools the mold by spraying, and cannot cooperate with air cooling to cool it. The cooling speed of the mold is slow, and then the processing efficiency of the aluminum alloy die-castings cannot be guaranteed. There are certain defects and deficiencies, and therefore it needs to be improved. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a production mold for aluminum alloy die-castings. By setting a circulating water barrel, the circulating water barrel can recycle the water used by the spraying mechanism and cool it to achieve its recycling, which has better energy saving and cooling effects. It can achieve effective cooling of the mold, and then ensure the processing speed of aluminum alloy die-castings, solving the problem of poor cooling effect of the current device.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A production mold for aluminum alloy die castings, comprising:

[0007] Workbench;

A cooling sleeve is fixedly connected to the bottom of the lower mold base, and the cooling sleeve is fixedly connected to the workbench. An outer wall of the lower mold base is provided with equidistantly distributed annular cooling grooves.

[0009] The circulating water barrel includes a barrel body and an annular semiconductor refrigeration plate embedded in the inner wall of the barrel body. The top of the barrel body is integrally formed with a convex edge, which is fixed on the workbench and has a cover plate. The drainage pipe connected to the bottom of the cooling sleeve extends into the barrel body through the cover plate.

[0010] Furthermore, an annular cylinder is fixedly connected to the inner center of the barrel body.

[0011] Furthermore, an annular pipe is fixed on the fixing piece provided on the inner wall of the cooling sleeve, and the annular pipe is connected to the nozzles distributed in an array.

[0012] Furthermore, a water inlet interface is provided on the annular pipe, and a circulating water pump is installed on the workbench. A water inlet hose is connected between the circulating water pump and the water inlet interface. A circulating pipe is connected to the water inlet of the circulating water pump, and the circulating pipe extends to the inner bottom of the barrel body through the cover plate.

[0013] Furthermore, both sides of the cooling sleeve are connected to an air intake pipe and an exhaust pipe respectively, and an exhaust fan is installed on the air intake pipe.

[0014] Furthermore, a feed port is provided on the upper die base, and a sealing cover is provided on the stop block fixed on the upper part of the cooling sleeve, and the sealing cover is provided between the lower die base and the cooling sleeve.

[0024] It should be noted that the workbench 1 is used for loading and supporting the mold module 2, the circulating water pump 4 and the circulating water barrel 5. The lower mold base 201 cooperates with the upper mold base 202 to realize the processing of aluminum alloy die-castings. The processing method of the mold for aluminum alloy die-castings is a known existing technology and will not be described in detail. By fixing the cooling sleeve 2012 at the bottom of the lower mold base 201, the cooling sleeve 2012 is covered on the outer side of the lower mold base 201, which is convenient for spraying and cooling the lower mold base 201. By providing an annular cooling groove 2011 on the lower mold base 201, the heat dissipation surface of the lower mold base 201 can be increased, thereby accelerating the lower mold base 201. For cooling, a circulating water barrel 5 is arranged on the workbench 1, and the water in the cooling sleeve 2012 can be discharged into the inner side of the barrel body 501 through the drain pipe 504. By embedding an annular semiconductor refrigeration plate 502 on the outer wall of the barrel body 501, the annular semiconductor refrigeration plate 502 can cool the water inside the barrel body 501, and then it can be recycled and the cooling effect of the lower mold base 201 is guaranteed. By arranging a convex edge 503 on the top of the barrel body 501, a circular cavity is arranged on the workbench 1 when in use, the barrel body 501 is fitted in the circular cavity, and the circulating water barrel 5 is fixed on the workbench 1 by the convex edge 503.

[0026] It should be noted that the setting of the annular cylinder 507 can concentrate water on the inner periphery of the barrel body 501, making it easier for the annular semiconductor refrigeration plate 502 to cool the water and avoid the problem of poor cooling effect at the center.

[0031] like Figure 2 As shown, in some embodiments, an air inlet pipe 2014 and an exhaust pipe 206 are connected to both sides of the cooling sleeve 2012 , respectively, and an exhaust fan 2013 is installed on the air inlet pipe 2014 .

[0032] It should be noted that by connecting the air inlet pipe 2014 and the exhaust pipe 206 to the cooling sleeve 2012, air intake and exhaust can be performed. By installing the exhaust fan 2013 on the air inlet pipe 2014, the exhaust fan 2013 can draw the outside air into the inner side of the cooling sleeve 2012. The wind flows along the annular cooling groove 2011, and the lower mold base 201 is cooled by the spraying water droplets, which has a better cooling effect.
