Description

Technical Field

[0001] The utility model relates to the technical field of metal liquid die casting, in particular to a die casting device. Background Art

[0002] Die-casting equipment is mainly used to inject molten metal solution into a mold, thereby manufacturing precise metal parts or products through die-casting molding technology. During this process, the molten metal remains liquid at high temperature and, with the help of high pressure and rapid cooling, quickly solidifies in the precise shape of the mold to form the desired product appearance and internal structure.

[0003] A significant shortcoming of existing die-casting devices, especially in the production process of metal parts such as pot bodies, is that they are highly dependent on manual unloading. This traditional practice is not only inefficient, but also has safety hazards that cannot be ignored. Since the metal solution needs to be kept at an extremely high temperature during the die-casting process to maintain its fluidity and ensure the molding quality, this makes the work site environment extremely harsh, with high temperature and high heat radiation. In this environment, workers need to come into close contact with the high-temperature metal solution and molds to perform unloading operations. When exposed to high-temperature environments for a long time, workers will experience a process of rapid evaporation of water in their bodies, leading to frequent health problems such as dehydration and heatstroke, which may even be life-threatening in severe cases. In addition, high temperatures also aggravate workers' fatigue, reduce work efficiency and concentration, and further increase the risk of operational errors and accidents. Therefore, people in this technical field provide a die-casting device to solve the problems raised in the above background technology. Utility Model Content

[0029] Working principle: The support mechanism 2 is the core foundation of the die-casting device and is firmly fixed to one side of the heat shield 1 through the base plate 201. The mounting plate 202 thereon carries and supports the flip mechanism 7, the drive mechanism 3, the first transmission mechanism 5 and the second transmission mechanism 6. The first bearing 203 and the second bearing 204 respectively ensure the smooth rotation of the transmission rod 503 and the support rod 701 to reduce friction and wear.

In the drive mechanism 3, the hydraulic rod 301 serves as The power source, its telescopic movement drives the rack 303 to translate, and the rack 303 drives the driving gear 504 in the first transmission mechanism 5 to rotate through the meshing transmission, thereby driving the transmission rod 503 to rotate, and the first transmission gear 601 on both sides of the transmission rod 503 is engaged with the second transmission gear 602 in the second transmission mechanism 6, and the power is transmitted to the support rod 701. When the support rod 701 rotates, it drives the docking disc 702 and the splint 703 to rotate, realizing the flipping of the lower die-casting mechanism 8. After the flip, the lower die-casting mechanism 8 delivers the pot body in the die-casting mold groove 803 into the heat insulation cover 1, completing the die-casting and preliminary cooling storage process. The entire device has a stable structure and precise transmission, ensuring the safety and efficiency of the die-casting operation.
