Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-casting mold components technology, and more specifically to a heat-insulating cylinder for rapid cooling of molten metal. Background Technology
[0002] Pressure casting is a rapidly developing special casting method in modern metal processing technology, involving minimal or no cutting. It is a process in which molten metal is filled into a mold under high pressure and high speed, and then crystallized and solidified under high pressure to form a casting.
[0003] During the die casting process, when dealing with thin-walled parts, rapid cooling of the injection end is usually required. However, the traditional cooling method is to cool the injection end through the cooling circuit of the entire barrel, which cannot achieve rapid cooling. This results in slow die casting efficiency for thin-walled parts. In addition, the barrel is in frequent alternation between hot and cold during use, which can lead to cracking of the inner hole of the barrel and a shortened service life of the barrel. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat-insulating cylinder for rapid cooling of molten metal. By setting several water grooves at the injection end and injecting water at 130°C for rapid cooling, it ensures rapid forming of thin-walled parts during die casting. By setting several oil grooves at the feed end and injecting oil at 250°C for cooling and heat preservation of the cylinder, it solves the problem of cracking of the inner hole caused by frequent heating and cooling of the cylinder, thereby increasing the frequency of cylinder use.
[0005] The technical solution of this utility model is as follows:
[0006] A heat-insulating barrel for rapid cooling of molten metal includes a barrel body, an injection end, and a feed end. A cooling component is provided on the injection end, and the cooling component includes several water tanks disposed on the injection end. A heat-insulating component is provided on the feed end, and the heat-insulating component includes several oil tanks disposed on the feed end. The cooling component rapidly cools the injection end through the several water tanks, and the heat-insulating component cools and insulates the feed end through the several oil tanks.
[0007] As a preferred embodiment, the cooling assembly further includes an inlet and an outlet hole formed in the water tank.
[0008] As a preferred embodiment, the heat insulation component further includes several oil inlet holes and several oil outlet holes disposed on the oil tank.
[0009] As a preferred embodiment, several of the water tanks are configured as a ring-shaped cooling circuit structure.
[0010] As a preferred option, the water tanks are filled with water at 130°C.
[0011] As a preferred embodiment, several of the oil tanks are configured as a semi-circular heat-insulating circuit structure, with the semi-circular heat-insulating circuit gradually shortening.
[0012] As a preferred option, the oil tanks described herein are filled with oil at 250°C.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model is equipped with a cooling component. After the water is pressurized to 130°C, it is injected into the water tank to rapidly cool the injection end, so as to achieve the effect of rapid forming when die-casting thin-walled parts.
[0015] 2. This utility model is also equipped with a heat preservation component. By injecting oil at 250°C into the oil tank, the material cylinder body is cooled and kept warm, which solves the problem of cracking of the inner hole of the material cylinder body due to frequent heating and cooling, extends its service life, and increases its usage frequency.
[0016] In summary, this invention has the advantages of fast cooling speed and good heat preservation effect, and is suitable for the field of die casting mold parts technology. Attached Figure Description

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0023] Example 1
[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0025] like Figures 1 to 3 As shown, a heat-insulating cylinder for rapid cooling of molten metal includes a cylinder body 1, an injection end 2, and a feed end 3. A cooling component 4 is provided on the injection end 2, and the cooling component 4 includes several water tanks 41 provided on the injection end 2. A heat-insulating component 5 is provided on the feed end 3, and the heat-insulating component 5 includes several oil tanks 51 provided on the feed end 3. The cooling component 4 rapidly cools the injection end 2 through the several water tanks 41, and the heat-insulating component 5 cools and insulates the feed end 3 through the several oil tanks 51.
[0026] Among them, such as Figure 2 As shown, the cooling assembly 4 also includes a water inlet hole 42 and a water outlet hole 43 opened on the water tank 41. Water enters into the water tank 41 through the water inlet hole 42 and finally flows out from the water outlet hole 43, achieving the effect of rapid cooling of the injection end 2, which can quickly form thin-walled parts during die casting.
[0027] In addition, such as Figure 3 As shown, the heat preservation component 5 also includes several oil inlet holes 52 and several oil outlet holes 53 provided on the oil tank 51. Oil enters the oil tank 51 through the oil inlet holes 52 and finally flows out from the oil outlet holes 53, cooling and heat preservation of the middle and bottom of the barrel body 1, keeping the barrel at the set temperature, reducing the temperature difference between hot and cold, solving the problem of cracking of the inner hole of the barrel body 1 caused by frequent heating and cooling, and increasing the usage frequency of the barrel body 1.
[0028] It is worth mentioning that, such as Figure 2 As shown, several water tanks 41 are configured as a ring-shaped cooling circuit structure to improve the cooling effect.
[0029] Furthermore, such as Figure 2 As shown, several water tanks 41 are filled with water at 130°C. After the water circuit is pressurized by 3MB, the water temperature is raised to 130°C, which achieves rapid cooling of the injection end 2 and rapid forming of thin-walled parts.
[0030] It should be further explained that, such as Figure 3 As shown, several oil tanks 51 are configured as a semi-circular heat preservation circuit structure, and the semi-circular heat preservation circuit gradually shortens to provide all-round cooling and heat preservation for the barrel body 1.
[0031] In addition, such as Figure 3 As shown, several oil tanks 51 are filled with oil at 250°C. The material cylinder is cooled and kept warm by the oil at 250°C, which reduces the damage to the material cylinder body 1 caused by frequent hot and cold cycles.
[0032] Work process
[0033] Water at 130°C enters the water tank 41 through the water inlet 42 and then flows out through the water outlet 43, rapidly cooling the injection end 2 and enabling the rapid forming of thin-walled parts. Oil at 250°C enters the oil tank 51 through the oil inlet 52 and then flows out through the oil outlet 53, cooling and insulating the middle and bottom of the barrel body 1. This solves the problem of cracking of the inner hole of the barrel body 1 due to frequent heating and cooling, and increases the frequency of use of the barrel body 1.
