Description

Technical Field

[0001] This invention relates to the field of automotive structural component die casting technology, specifically a high-performance aluminum alloy die casting equipment for automotive structural components. Background Technology

[0002] Die casting equipment is a machine used for pressure casting, including both hot and cold pressing chambers. Both are further divided into vertical and horizontal types. Under pressure, die casting equipment injects molten metal into a mold to cool and solidify, resulting in a solid metal casting after mold opening.

[0003] In existing die-casting equipment, the clamping force is provided by the press of the moving platen during die casting. When the injection pressure is too high, the moving platen will slide, affecting the clamping force and resulting in poor casting quality. Furthermore, the clamping force provided by the press is only provided in the direction of sliding of the moving platen, which can easily cause vibration during injection pressure, affecting the molding effect.

[0004] To address the above problems, this invention provides a high-performance aluminum alloy die-casting equipment for automotive structural components, thereby solving the aforementioned issues. Summary of the Invention

The inclined sliding hole of the self-locking component allows the self-locking column to form a self-locking angle under air pressure, which, together with the synchronous air intake system, achieves multi-point synchronous clamping. The reset spring ensures rapid automatic unlocking after pressure relief, effectively avoiding the safety risk of accidental mold opening during die casting. The clamping component can apply a rotational clamping force to the moving mold plate, improving the clamping strength. The pressurizing component, the self-locking component, and the clamping component can provide clamping force in multiple directions, and the stability of clamping is improved through multiple clamping.

[0049] Reference Figures 1-5 This invention provides a technical solution: a high-performance aluminum alloy die-casting equipment for automotive structural components, comprising:

[0050] Base 1, with a pressure injection device 2 fixed to its upper end surface;

[0051] Support 3 is fixed on the base 1;

[0052] The movable template 4 is slidably mounted on the support base 3;

[0053] The press 5 is fixed inside the support base 3, and its output end is connected to the bottom of the moving template 4;

[0054] The template 6 is fixed on the support base 3 and is connected to the pressure injection device 2;

[0055] The pressurization component 7 is fixed on the support base 3, and its output end is connected to the moving template 4;

[0056] Multiple self-locking components 8 are configured and slidably disposed within the fixed template 6;

[0057] The locking assembly 9 is installed on the upper surface of the support base 3.

[0058] In this embodiment, the booster assembly 7 includes:

[0059] The fixing plate 71 is fixed on the support base 3;

[0060] Four guide shafts 72 are configured and fixed to one side of the fixed plate 71, and the moving template 4 is slidably connected to the guide shafts 72.

[0061] Two guide columns 73 are configured and symmetrically fixed on the fixed plate 71, and are slidably connected to the moving template 4;

[0062] The booster cylinder 74 is fixed on the fixed plate 71;

[0063] The sliding head 75 is slidably mounted on the two guide posts 73 and connected to the output end of the booster cylinder 74;

[0064] Two hinge plates 76 are configured, one end of which is symmetrically hinged to the sliding head 75, and the other end is hinged to one end of the pressing plate 77, the other end of which is hinged to the moving template 4.

[0065] It should be noted that the booster cylinder 74 and the press 5 operate synchronously. When the moving platen 4 completes the mold closing through the press 5, the booster cylinder 74 continues to extend, causing the hinge plate 76 to pull the pressing plate 77, thereby applying a clamping force in the tilt direction.

[0066] In this embodiment, the self-locking component 8 includes:

[0067] Multiple sliding holes 81 are configured and are all inclinedly opened at the four corners of the fixed template 6;

[0068] The self-locking pin 82 is slidably disposed in the sliding hole 81, and a return spring 83 is disposed between the pin and the sliding hole 81.

[0069] Multiple air inlets 84 are configured and opened on the fixed template 6, corresponding to the sliding holes 81.

[0070] In a preferred embodiment, the moving template 4 is provided with a self-locking hole at the position corresponding to the sliding hole 81, and the plurality of air inlets 84 are for synchronous air intake.

[0071] In other words, the inclined sliding hole 81 enables the self-locking pin 82 to form a self-locking angle under air pressure, which, together with the synchronous air intake system, achieves multi-point synchronous mold locking. The reset spring 83 ensures rapid automatic unlocking after pressure relief, effectively avoiding the safety risk of accidental mold opening during the die casting process.

[0072] In this embodiment, the mold-locking assembly 9 includes:

[0073] The drive assembly is fixed inside the base 1;

[0074] Two adjustment components are configured and symmetrically slidably disposed on the base 1 and connected to the output end of the drive component.

[0075] In a preferred embodiment, the driving component includes:

[0076] The base plate 91 is fixed inside the base 1;

[0077] Two screws 92 are configured and symmetrically rotatably mounted on the base plate 91, and the threads of the two screws 92 are opposite in direction;

[0078] The sliding element 93 is threadedly connected to the screw 92.

[0079] It should be noted that the two screws 92 are driven by a drive motor to ensure that the two sliding parts 93 move synchronously.

[0080] In a preferred embodiment, the adjustment component includes:

[0081] The drive plate 94 is slidably mounted on the base 1 and is fixedly connected to the sliding member 93;

[0082] The sliding plate 95 is fixed to the upper end face of the drive plate 94;

[0083] Locking templates 96 are configured in two, symmetrically hinged at both ends of the sliding plate 95;

[0084] The connecting rod 97 has one end fixed to the locking template 96 and the other end hinged to a sliding rod 98;

[0085] The limiting block 910 is slidably disposed in the middle position of the sliding plate 95, and the two ends of the limiting block 99 are fixed with limiting posts 99, which are slidably connected to the sliding rod 98.

[0086] The push column 911 is fixed inside the limiting block 910, with a pressing plate 912 fixed at one end and a reset plate 914 fixed at the other end;

[0087] The reset chamber 913 is fixed to one side of the sliding plate 95 and is slidably connected to the reset disk 914. A reset spring 915 is provided between the reset chamber 913 and the reset disk 914.

[0088] During mold locking, the sliding member 93 drives the drive plate 94 to move closer to each other, thereby causing the pressing plate 912 to contact the moving template 4 and the fixed template 6, causing the limit block 910 to slide and the two locking templates 96 to rotate, thereby rotating and locking the moving template 4 and the fixed template 6 to improve the mold locking strength.

[0089] Specifically, firstly, the press 5 drives the moving platen 4 to slide towards the fixed platen 6 until the mold parting surface closes. Then, the pressure boosting component 7 increases the clamping force of the moving platen 4, and the pressing plate 77 applies a force in the tilting direction to the moving platen 4, thereby providing clamping force in multiple directions. The self-locking column 82 forms a self-locking angle under air pressure through the tilting sliding hole 81 of the self-locking component 8, and the synchronous air intake system achieves multi-point synchronous clamping. Then, the clamping component 9 applies a rotational clamping force to the moving platen 4 to increase the clamping strength, thereby applying clamping force in multiple directions to the moving platen 4, and improving the stability of clamping through multiple clamping. Finally, the pressure injection device 3 injects molten aluminum alloy to complete the die casting.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
