Description

Technical Field

[0001] This utility model relates to the field of molds for integrated die casting, and more specifically to molds for integrated die casting. Background Technology

[0002] See Figure 3 , Figure 4 In integrated die-casting molds, the mating surface 20 between the sliding side mold 2 and the fixed mold 3 is usually parted according to the shape of the die-cast product, i.e., it follows the mold shape. This mating surface 20 is usually a horizontal surface, located at the upper end of the sliding side mold 2 and on the outside of the cavity 5, directly connected to the cavity 5. The following shape of the mating surface 20 makes its machining precision difficult, easily leading to inaccuracies and large clearances between the sliding side mold 2 and the fixed mold 3, resulting in flash and aluminum runoff. Flash and aluminum runoff are detrimental to die-casting production, requiring a large amount of work for deburring and polishing. Severe aluminum runoff can cause equipment burns and even injuries. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an integrated die-casting mold. By adding an additional first mating surface between the sliding side mold and the fixed mold, it avoids excessive gaps between the sliding side mold and the fixed mold, which can cause flash and aluminum run-out.

[0004] The technical solution of this utility model is as follows: an integrated die-casting mold, including a sliding side mold, a fixed mold, and a moving mold, wherein the sliding side mold forms a cavity with the fixed mold and the moving mold, and two mating surfaces are provided between the sliding side mold and the fixed mold, wherein the first mating surface is located outside the cavity and at the front end of the sliding side mold; the second mating surface is located outside the first mating surface and at the upper end of the sliding side mold, and both the first mating surface and the second mating surface are inclined planes.

[0005] The inclination angle of the first mating surface is 1.5° to 5°.

[0006] The inclination angle of the second mating surface is 3° to 15°.

[0007] The sliding side mold is fixedly installed on the slide block.

[0008] The sliding side mold is driven by a cylinder.

[0009] The advantages of this invention are as follows: The invention adds a first mating surface between the sliding side mold and the fixed mold, and the first mating surface is located outside the cavity and in front of the sliding side mold. Furthermore, both the first and second mating surfaces are set as inclined planes. When the cylinder drives the sliding side mold to move towards the front end, the first and second mating surfaces enable the sliding side mold and the fixed mold to fit more closely, avoiding large gaps and preventing flash and aluminum run-out problems in the die-cast products.

[0010] Glossary

[0011] Integrated die casting: Integrated die casting is an innovative manufacturing process that integrates multiple complex parts from a car's body-in-white into a single component using die casting. First proposed by Tesla in 2019, it was applied to the production of the Model Y's rear floor panel in 2020. This technology uses a large die casting machine to inject molten metal into a mold to form the final part, thus achieving the one-time molding of multiple components. This not only simplifies the manufacturing process but also improves production efficiency, bringing new possibilities for lightweighting in the automotive industry. Attached Figure Description

[0016] See Figures 1 to 2 The integrated die-casting mold includes a sliding side mold 2, a fixed mold 3, and a moving mold 4. The sliding side mold 2 is fixedly mounted on a slide block 1 and is driven by a cylinder. A cavity 5 is formed between the sliding side mold 2, the fixed mold 3, and the moving mold 4. Two mating surfaces are provided between the sliding side mold 2 and the fixed mold 3. The first mating surface 21 is located outside the cavity 5 and at the front end of the sliding side mold 2; the second mating surface 22 is located outside the first mating surface 21 and at the upper end of the sliding side mold 2. Both the first mating surface 21 and the second mating surface 22 are inclined planes. The inclination angle of the first mating surface 21 is 1.5° to 5°, and the inclination angle of the second mating surface 22 is 3° to 15°. This arrangement allows the sliding side mold 2 to better fit with the fixed mold 3 when moving at the front, avoiding large gaps between the mating surfaces and solving the problems of flash and aluminum runout in die-cast products.
