Description

Technical Field

[0001] The utility model relates to the technical field of alloy vehicles, in particular to a high-sealing die-casting mold. Background Art

[0002] The die-casting mold is a mold used to inject molten metal into the die-casting machine. Materials with good mechanical properties and wear resistance, such as tool steel, cemented carbide, etc., are selected to ensure that the mold has a long service life and good sealing performance. Precision machining technology is used to ensure the machining accuracy and surface quality of mold parts to reduce the sealing gap and improve the sealing performance. Combined with the existing literature, a high-sealing die-casting mold (CN216461675U) includes a base, a lower mold is fixedly connected to the center of the top of the base, a sealing frame is fixedly connected to the outer wall of the lower mold, a sealing door is hinged on one side of the sealing frame, and the four corners of the top of the base are fixedly connected to columns, the top of the column is fixedly connected to a mounting frame, and the outer top of the mounting frame is fixedly connected to a hydraulic rod, the bottom of the telescopic end of the hydraulic rod passes through the mounting frame and is fixedly connected to the upper mold, and the outer wall of the upper mold is fixedly connected to a sealing ring. The utility model cooperates with the sealing frame and the sealing door, and a sealing frame is provided on the outside of the upper and lower molds. When the die-casting process is performed, the sealing is stronger, which effectively prevents the leakage and splashing of the workpiece raw material. At the same time, after the processing is completed, the lock is opened to facilitate the user to open the sealing door, so as to quickly take the processed workpiece. It can be seen that at least the following defects are exposed during use:

[0003] 1. In the process of using today's die-casting molds, since most of the mounting frames and columns are welded, when the die-casting mold needs to inspect the structure of the mounting frames and columns, it is difficult to repair and disassemble, which is inconvenient.

[0004] 2. During the use of today's die-casting molds, when the mold needs to be cooled, it is usually necessary to wait for the mold to cool naturally, which takes a long time, or to cool the mold by watering. However, cooling by watering consumes a lot of water resources, resulting in a waste of resources. Utility Model Content

[0005] The utility model aims to provide a high-sealing die-casting mold to solve the problems of the existing die-casting mold in the use process mentioned in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] Preferably, the water tank is connected to the cooling tank via a water inlet pipe and a water outlet pipe.

[0010] Preferably, two cylinders are installed on the upper end of the fixed plate, and a liquid injection pipe is installed in the middle of the upper end of the fixed plate.

[0011] Preferably, an upper die seat is installed at the lower ends of the two cylinders, and a liquid injection pipe is provided at the upper end of the upper die seat.

[0012] Preferably, a sealing plate is installed at the lower end of the upper die base, and two sliding blocks are installed at the left and right ends of the upper die base, and the interiors of the sliding blocks are movably connected to second positioning rods.

[0013] Preferably, a sealing groove is provided inside the lower die base, and the size of the sealing plate matches the sealing groove.

[0014] The embodiment of the utility model provides a high-sealing die-casting mold, which has the following beneficial effects:

[0015] 1.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1-3As shown, a high-sealing die-casting mold comprises a base 1, a lower mold base 9 is installed on the upper end of the base 1, a water tank 2 is installed on the left end of the base 1, and an inlet pipe 10 and an outlet pipe 19 are arranged on the upper end of the water tank 2. Water circulation is carried out through the inlet pipe 10 and the outlet pipe 19. Eight screws 14 are connected to the inner thread of the base 1, and four second positioning rods 7 and four first positioning rods 6 are fixedly installed on the upper ends of the eight screws 14. The upper and lower ends of the four first positioning rods 6 are fixedly installed with screws 14, and the upper and lower ends of the four second positioning rods 7 are fixedly installed with screws 14. The eight screws 14 penetrate the fixed plate 3 and are threadedly connected with the four first fixed blocks 4 and the four second fixed blocks 5. When the die-casting mold needs to be repaired, the second fixed block 5, the first fixed block 4 and the outer side of the screw 14 are twisted out first, and the fixed plate 3 and the slider 1 can be fixed. 3 is taken out from the outside of the first positioning rod 6 and the second positioning rod 7, and then the screw 14 at the lower ends of the first positioning rod 6 and the second positioning rod 7 is twisted out from the inside of the base 1, so that the detachable part of the die-casting mold can be repaired and replaced, so it is relatively convenient. Two cylinders 16 are installed at the upper end of the fixed plate 3, and a liquid injection pipe 17 is installed in the middle of the fixed plate 3. The lower ends of the two cylinders 16 are installed with an upper die seat 8. The upper end of the upper die seat 8 is provided with a liquid injection pipe 17. The upper die seat 8 is driven to extend and retract up and down by the two cylinders 16. Two sliders 13 are installed at the left and right ends of the upper die seat 8. The inside of the slider 13 is movably connected with the second positioning rod 7. The upper die seat 8 is assisted in positioning by the slider 13. A sealing plate 11 is installed at the lower end of the upper die seat 8. The sealing plate 11 is inserted into the inside of the sealing groove 12 to make the upper die seat 8 and the lower die seat 9 more sealed.

[0025] like Figure 4 As shown, a first water pump 20 and a second water pump 21 are installed at the upper end of the interior of the water tank 2. The first water pump 20 is installed on the outer side of the water outlet pipe 19, and the second water pump 21 is installed on the outer side of the water inlet pipe 10. A copper tube radiator 18 is installed inside the water tank 2, and the water is cooled by the copper tube radiator 18. The water tank 2 is connected to the water inlet pipe 10 and the cooling tank 15 through the water outlet pipe 19. When the die-casting mold needs to be cooled, the second water pump 21 is started to transport the water inside the water tank 2 to the inside of the cooling tank 15 through the water inlet pipe 10. After circling around the inside of the cooling tank 15, the first water pump 20 cooperates with the water outlet pipe 19 to transport the cooled water to the inside of the water tank 2. The cooled water is cooled by the copper tube radiator 18 inside the water tank 2. Such a reciprocating heat dissipation can avoid consuming too much water resources and avoid waste of resources.

[0026] Working principle: When the die-casting mold needs to be cooled, the second water pump 21 is started to transport the water inside the water tank 2 to the inside of the cooling tank 15 through the water inlet pipe 10. After circling the inside of the cooling tank 15, the first water pump 20 cooperates with the water outlet pipe 19 to transport the cooled water to the inside of the water tank 2. The cooled water is cooled by the copper tube radiator 18 inside the water tank 2. Such a reciprocating heat dissipation can avoid consuming too much water resources and waste of resources. When the die-casting mold needs to be repaired, the second fixing block 5, the first fixing block 4 and the outside of the screw 14 are first twisted out, and the fixing plate 3 and the slider 13 can be taken out from the outside of the first positioning rod 6 and the second positioning rod 7. Then, the screw 14 at the lower end of the first positioning rod 6 and the second positioning rod 7 is twisted out from the inside of the base 1, and the detachable part of the die-casting mold can be repaired and replaced, so it is more convenient.
