Technical Field

[0002] Automotive parts, especially aluminum alloy components, are mostly formed using die-casting dies. For particularly complex automotive parts, the die-casting dies used are often equally complex. Failure to properly design the die-casting die's feed system during the die design phase can result in an overly large die. This, in turn, necessitates the use of a large-tonnage die-casting machine, sometimes even facing the problem of unavailability. Consequently, using large-tonnage die-casting machinery to produce a single product significantly increases the molding cost per product. Utility Model Content

DETAILED DESCRIPTION
[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0027] A die-casting mold for producing new energy vehicle parts, comprising a fixed mold assembly; a movable mold assembly 1, which is movably matched with the fixed mold assembly and forms a product cavity between the fixed mold assembly and the movable mold assembly 1 when the movable mold assembly 1 and the fixed mold assembly are in affixed relationship; a feed channel, which has a main channel 2 arranged at one end of the movable mold assembly 1 and / or the fixed mold assembly, and a transition section at one end of the main channel 2 extending outward toward the bottom wall away from the main channel 2, and the transition section is connected to the product cavity; an extrusion assembly 3, which is connected to the movable mold assembly 1, and the extrusion assembly 3 has an extrusion rod 4, and the extrusion rod 4 has a first active state in which one end extends into the main channel 2, and a second active state in which one end retracts into the movable mold assembly 1, and the second active state is used to allow the metal raw material in the main channel 2 to flow into the product cavity; the metal raw material retained on the transition section can be subjected to a thrust toward the product cavity due to the extrusion rod 4 switching from the second active state to the first active state.
[0028] Based on the above embodiment, an exemplary structure of this solution is as follows: Figures 1 to 5As shown, in the initial state, the extrusion assembly 3 drives the extrusion rod 4 to retract inward into the movable die assembly 1, allowing the raw metal to pass smoothly through the main runner 2 and into the product cavity. During operation, the die-casting machine's feed system directs molten metal into the main runner 2. The end of the main runner 2 closest to the product cavity is equipped with a transition section extending outward from the bottom wall of the main runner 2. This section is designed to reduce the actual entrance size to the cavity. This design is intended to increase the filling pressure when entering the product cavity, thereby making the die-casting mold compatible with smaller-tonnage die-casting machines. Subsequently, after the product cavity is fully filled, the extrusion assembly 3 drives the extrusion rod 4 to move along the movable die assembly 1 toward the fixed die assembly. As the extrusion rod 4 moves, it applies lateral pressure to the molten metal in the transition section, forcing some of the molten metal into the product cavity. This process increases the fill volume within the product cavity without increasing the injection pressure of the die-casting machine, further facilitating production using die-casting machines with lower injection pressures.
[0029] Both sides of the transition section along the feeding direction are provided with inclined grooves 5 , which are connected to the product cavity, and the thickness of the inclined grooves 5 gradually decreases along the feeding direction.
[0030] The thickness of the chute 5 is set to gradually decrease along the feeding direction, which is also used to increase the injection pressure during the product cavity feeding process.
[0031] The chutes 5 are evenly inclined along the feeding direction of the metal raw material, and the distance between the two chutes 5 away from one end of the product cavity is greater than the distance between the other ends of the two chutes 5. The purpose of this design is to ensure that the molten metal entering the product cavity will not only gather at one feeding point, but can be distributed more evenly when filling the product cavity.
[0032] The extrusion assembly 3 includes: a driving member 16, which is connected to the movable mold assembly 1; a first connecting sleeve 6, which is connected to the driving member 16; a connecting rod 7, which is movably inserted in the first connecting sleeve 6, one end of the connecting rod 7 is connected to the output end of the driving member 16, and the end of the extrusion rod 4 away from the main channel 2 is clamped on the connecting rod 7; a second connecting sleeve 8, which is connected to the movable mold assembly 1 and connected to the end of the first connecting sleeve 6 away from the driving member 16; a stripping sleeve 9, which is inserted into the movable mold assembly 1 and sleeved on the outside of the extrusion rod 4, and one end of the stripping sleeve 9 is clamped on the second connecting sleeve 8.
[0033] During operation, the driving member 16 drives the extrusion rod 4 to move by driving the connecting rod 7, thereby switching the extrusion rod 4 between the first active state and the second active state. The stripping sleeve 9 is used to scrape off metal debris adhered to the extrusion rod 4 when the extrusion rod 4 is in the second active state to prevent the extrusion rod 4 from getting stuck. The second connecting sleeve 8 is used to fix the stripping sleeve 9 on the movable mold assembly 1.
[0034] Preferably, a first T-slot 10 is provided on the connecting rod 7, and the first T-slot 10 passes through the side wall of the connecting rod 7; a second T-slot 11 is provided on the second connecting sleeve 8, and the second T-slot 11 passes through the side wall of the second connecting sleeve 8; a first hanging platform 12 is provided on the extrusion rod 4, and a second hanging platform 13 is provided on the stripping sleeve 9; the first hanging platform 12 is clamped in the first T-slot 10, and the second hanging platform 13 is clamped on the second hanging platform 13.
[0035] The first connecting sleeve 6 is provided with a through slot 14 penetrating the first connecting sleeve 6 , and the connecting rod 7 is provided with a mounting slot 15 communicating with the first T-slot 10 . The through slot 14 is used to expose the mounting slot 15 to the outside.
[0036] The extrusion rod 4 needs to be provided with a cooling water assembly when in operation, and the mounting groove 15 is used to fix the cooling water assembly. The through groove 14 exposes the mounting groove 15 to the outside to facilitate the connection of the water pipe on the cooling water assembly.
