[0022] Liquid metal auxiliary structure 5 includes top high-temperature module 51, support body 52, metal liquid collecting groove 53 and discharge pipeline 54, and top high-temperature module 51 and metal liquid collecting groove 53 are fixedly installed at one end of movable end cavity 3, and support body 52 is fixedly installed between top high-temperature module 51 and metal liquid collecting groove 53;Discharge pipeline 54 is fixedly installed at the bottom of metal liquid collecting groove 53.

[0023] Finished product cooling assembly 4 adopts two groups, and is mirror-imaged and arranged on the both sides of movable end cavity 3;Air cavity 42 adopts two groups of metal boxes, and guide cavity 43 turns gas outlet 44, so that gas outlet 44 faces the position of workpiece die casting forming;Discharge pipeline 54 can pass low-temperature gas into the inside of air cavity 42.

[0024] Top high-temperature module 51 in liquid metal auxiliary structure 5 adopts a group of infrared rapid heating equipment;Metal liquid collecting groove 53 adopts a steel metal groove, and metal liquid collecting groove 53 is located directly below punch structure 6 and inlet pipeline;Discharge pipeline 54 adopts a steel metal pipe and extends outward.

[0025] The working principle of aluminium alloy piece die casting equipment is that heated liquid metal is injected into the mold, and is rapidly cooled and formed under high pressure, to realize efficient aluminium alloy piece production.The equipment is mainly composed of support frame, fixed end cavity, movable end cavity, finished product cooling assembly, liquid metal auxiliary structure and punch structure, and each part works cooperatively to ensure that the die casting process proceeds smoothly.

[0026] 1.opening and closing of mold and injection of liquid metal

[0027] The die casting process first involves the opening and closing of the mold, which is composed of a fixed end cavity 2 and a movable end cavity 3. The fixed end cavity is fixed on the support base 1 of the equipment, while the movable end cavity is slidingly installed at one end of the fixed end cavity through guide columns, which can move forward and backward along the guide columns to achieve the closing and opening of the mold.

[0028] In the open mold state, the liquid aluminum alloy heated to the appropriate temperature is injected into the mold through the liquid metal auxiliary structure 5. The top end high temperature module 51 of the liquid metal auxiliary structure maintains the temperature of the metal liquid, keeping it in the ideal liquid state, so as to ensure that the liquid metal can be smoothly injected into the mold cavity.

[0029] 2. Mold closing and die casting

[0030] When the liquid metal is injected into the mold, the movable end cavity begins to slide and close tightly with the fixed end cavity. At this time, the punch structure 6 starts to work, applying high pressure to the liquid metal to make it fill the entire mold cavity and form the required aluminum alloy part shape. Under the action of high pressure, the liquid metal quickly fills all the details in the mold, ensuring that the finished product has high precision and complex geometry.

[0031] 3. Cooling of finished product

[0032] After die casting is completed, the castings are still in a high temperature state, at which time the finished product cooling assembly 4 starts to work to accelerate the cooling of the castings. The finished product cooling assembly sprays cold air through the air outlet 44 to the surface of the castings through the air cavity 42, achieving rapid cooling. The assembly is installed on both sides of the movable end cavity, and by controlling the direction and intensity of the cold air, it ensures uniform cooling of the castings and prevents deformation or internal defects due to uneven temperature changes.

[0033] In addition, the metal liquid collection groove 53 in the liquid metal auxiliary structure is used to collect excess liquid metal to avoid waste or leakage. The excess liquid metal is discharged from the equipment through the discharge pipeline 54 for further cooling and recycling.

[0034] 4. Mold opening and finished product removal

[0035] After the castings are cooled to the appropriate temperature, the castings have been solidified and can be smoothly removed from the mold, while the mold is ready for the next round of die casting cycle.

[0036] 5. Recycling of liquid metal

[0037] In each die casting process, the liquid metal auxiliary structure not only provides heating function, but also re-directs the excess liquid metal to the collection tank through the discharge pipeline for recycling, which not only ensures efficient use of liquid metal, but also reduces waste of raw materials, improves the economy and environmental protection of production.

[0038] Summary

[0039] The aluminum alloy part pressure casting equipment ensures high-quality forming of the aluminum alloy part through a series of precisely designed structures and components in combination with heating, pressure casting, high-pressure forming and rapid cooling technology, and in the whole working process, the heating, introduction, forming, cooling and recycling of the liquid metal are coordinated with each other, so that the high-efficiency and accurate pressure casting production process is realized.
