Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to an integrated die-casting mold for a cylinder body of a new energy vehicle. Background Art

[0002] Die-casting molds are tools used in the die-casting process and are crucial for manufacturing metal parts with complex shapes and high precision. Molten metal is rapidly injected into the die-casting mold's cavity under high pressure, and the finished product is removed after the metal cools and solidifies. In existing die-casting molds, when molding thicker-walled products, the product cavity volume increases, which causes more air to be trapped inside the cavity. If the air in the product cavity cannot be effectively exhausted, it will mix with the molten metal when it is injected, causing pores to form inside the molded product, reducing the product's density and strength, and thus affecting its mechanical properties.

DETAILED DESCRIPTION

[0044] 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.

[0045] like Figures 1 to 8 As shown, the utility model is an integrated die-casting mold for a cylinder body of a new energy vehicle, comprising:

[0046] Fixed mold assembly 1; movable mold assembly 2, movable mold assembly 2 and fixed mold assembly 1 are movably abutted against each other; sliding assembly 3, sliding assembly 3 is arranged on movable mold assembly 2; product cavity 4, product cavity 4 is arranged between fixed mold assembly 1, movable mold assembly 2 and sliding assembly 3, and product cavity 4 is used to provide space for product molding; vacuum pumping part 5, vacuum pumping part 5 is detachably arranged on fixed mold assembly 1, and vacuum pumping part 5 is used to extract air in product cavity 4, and vacuum pumping part 5 is provided with gas channel 51 and valve stem 52, one end of gas channel 51 is connected with product cavity 4, and the end of gas channel 51 away from product cavity 4 is connected with outside air, and valve stem 52 is movably inserted between gas channel 51 and product cavity 4; ejector 6, ejector 6 is arranged on movable mold assembly 2, and ejector 6 is used to eject the molded product.

[0047] During operation, the die-casting mold is connected to the die-casting machine, the fixed mold assembly 1 is connected to the fixed part of the die-casting machine, and the movable mold assembly 2 is connected to the movable part of the die-casting machine. The movable mold assembly 2 is driven by the movable part of the die-casting machine to open or close the die-casting mold. When the die-casting mold is closed, the vacuum element 5 extracts the air in the product cavity 4 and discharges the air to the outside through the gas channel 51. Subsequently, the valve stem 52 is moved to disconnect the product cavity 4 from the gas channel 51, so that the product cavity 4 maintains a negative pressure state. In this way, when the molten metal is injected into the product cavity 4, most of the air in the product cavity 4 has been discharged, and the air dissolved by the molten metal remains within the design range, avoiding the formation of air holes inside the molded product. After the die-casting mold completes product molding, the sliding assembly 3 separates from the product, and the ejector 6 pushes the product to separate the product from the movable mold assembly 2.

[0048] The vacuum pump 5 of this solution includes:

[0049] The driving member 53 is detachably arranged on the fixed mold assembly 1, and the output end of the driving member 53 is connected to the valve stem 52; the exhaust member 54 is connected to the end of the gas channel 51 away from the product cavity 4, and the exhaust member 54 is used to extract gas.

[0050] The valve stem 52 can switch between an open state and a closed state. When the fixed mold assembly 1 and the movable mold assembly 2 are in contact, the driving member 53 drives the valve stem 52 to move, connecting the gas passage 51 with the product cavity 4. At this time, the valve stem 52 is in the open state, and the exhaust member 54 extracts the air in the product cavity 4 and exhausts the air to the outside through the gas passage 51. After the air in the product cavity 4 is completely extracted, the driving member 53 drives the valve stem 52 to move again, causing the valve stem 52 to abut against the fixed mold assembly 1. At this time, the valve stem 52 is in the closed state, and the gas passage 51 is disconnected from the product cavity 4. This prevents molten metal from entering the gas passage 51 when injected into the product cavity 4, causing the gas passage 51 to become clogged.

[0051] In this solution, a cooling assembly 7 is movably inserted into the fixed mold assembly 1. The cooling assembly 7 includes a cooling channel 71. The cooling channel 71 is spiral. Cooling liquid flows through the cooling channel 71 to remove heat from the product.

[0052] When the fixed die assembly 1 and the movable die assembly 2 come into contact, molten metal is injected into the product cavity 4. The die-casting mold cools the exterior of the molten metal in the product cavity 4. Simultaneously, coolant flows through the cooling channel 71, cooling the interior of the molten metal in the product cavity 4. This simultaneous cooling of the exterior and interior of the molten metal avoids the situation where the exterior temperature of the molten metal decreases while the interior temperature remains high, leading to deformation of the cooled product due to thermal expansion and contraction.

[0053] The fixed mold component 1 of this solution includes:

[0054] The exhaust groove 11 is arranged on the bottom surface of the fixed mold assembly 1, and the exhaust groove 11 is connected to the product cavity 4; the confluence groove 12 is arranged on the bottom surface of the fixed mold assembly 1, and the confluence groove 12 is connected to the end of the exhaust groove 11 away from the product cavity 4; the buffer groove 13 is arranged on the bottom surface of the fixed mold assembly 1, and the buffer groove 13 is connected to the end of the confluence groove 12 away from the exhaust groove 11; the protrusion 14 is arranged on the bottom surface of the fixed mold assembly 1, and the protrusion 14 is arranged adjacent to the buffer groove 13.

[0055] like Figure 3 As shown, since there may be residual gas when the vacuum member 5 extracts the gas from the product cavity 4, when the molten metal is injected into the product cavity 4 and fills it, the molten metal containing gas will flow into the exhaust groove 11, so that there is no gas remaining in the molten metal in the product cavity 4, thus avoiding the formation of pores in the molded product. The molten metal that flows into the exhaust groove 11 continues to flow to the confluence groove 12, and the molten metal in the confluence groove 12 converges together and impacts the protrusion 14 during the flow process. Under the action of the protrusion 14, the flow rate of the molten metal is reduced and flows into the buffer groove 13, preventing the molten metal with too fast a flow rate from directly impacting the vacuum member 5 and causing damage to the vacuum member 5.

[0056] The fixed mold assembly 1 of this solution is provided with a fixing assembly 8, which includes:

[0057] 81, the fixing frame 81 is arranged on the fixed mold assembly 1, and the fixing frame 81 is provided with a slide groove 811; the connecting sleeve 82, the connecting sleeve 82 is connected to the output end of the driving member 53, the connecting sleeve 82 is provided with a through groove 821, and the through groove 821 is movably sleeved on the valve stem 52; the fixing plate 83, the fixing plate 83 is movably inserted on the slide groove 811, and the fixing plate 83 can move in the first direction and the second direction opposite to each other; the support seat 84, the support seat 84 is arranged on the fixing plate 83, and the driving member 53 is fixed on the upper end surface of the support seat 84; the baffle 85, the baffle 85 is detachably arranged on the side end surface of the fixing frame 81, and the fixing plate 83 is detachably arranged on the side end surface of the baffle 85; the fixing block 86, the fixing block 86 is movably arranged on the fixed mold assembly 1, and the end of the valve stem 52 away from the driving member 53 is movably inserted on the fixing block 86; the sensor 87, the sensor 87 is arranged on the fixing plate 83, and the sensor 87 is movably abutted against the connecting sleeve 82.

[0058] like Figure 6 、 Figure 7 As shown, when the vacuum pumping element 5 needs to be disassembled, the baffle 85 is first removed from the fixing frame 81, and then the fixing plate 83 is moved to the right from the fixing frame 81. The fixing plate 83 drives the support seat 84 to move, and the support seat 84 drives the driving member 53 to move, and the driving member 53 drives the connecting sleeve 82 to move. Under the movement of the connecting sleeve 82, the through groove 821 is separated from the valve stem 52. After the driving member 53 is disassembled, the connecting pipe forming the gas channel 51 is pulled out to the right, and then the valve stem 52 is moved downward. The valve stem 52 drives the fixing block 86 to move, thereby removing the vacuum pumping element 5 from the fixed mold assembly 1. This disassembly method is faster. When the support seat 84 becomes loose, the support seat 84 cannot stably limit the connecting sleeve 82, which may cause the connecting sleeve 82 to move and then abut against the sensor 87. The sensor 87 sends a signal to remind the staff to re-fix the support seat 84 to avoid affecting the operation of the vacuum pumping element 5.

[0059] The sliding assembly 3 of this solution includes a first oil cylinder 31, a second oil cylinder 32, a third oil cylinder 33, a fourth oil cylinder 34 and a first slider 35, a second slider 36, a third slider 37, and a fourth slider 38. The first oil cylinder 31, the second oil cylinder 32, the third oil cylinder 33, and the fourth oil cylinder 34 are sequentially connected to the outer wall of the movable mold assembly 2, the first oil cylinder 31 and the third oil cylinder 33 are arranged opposite to each other, and the second oil cylinder 32 and the fourth oil cylinder 34 are arranged opposite to each other; the first slider 35, the second slider 36, the third slider 37, and the fourth slider 38 are sequentially slidably arranged on the movable mold assembly 2, the first slider 35 is connected to the output end of the first oil cylinder 31, the second slider 36 is connected to the output end of the second oil cylinder 32, the third slider 37 is connected to the output end of the third oil cylinder 33, and the fourth slider 38 is connected to the output end of the fourth oil cylinder 34.

[0060] When the fixed mold assembly 1 and the movable mold assembly 2 are closed, a product cavity 4 is formed between the fixed mold assembly 1, the movable mold assembly 2, and the sliding assembly 3. Molten metal is injected into the product cavity 4 and forms a product after cooling. After the product is formed, the fixed mold assembly 1 is separated from the movable mold assembly 2. The first oil cylinder 31, the second oil cylinder 32, the third oil cylinder 33, and the fourth oil cylinder 34 respectively drive the corresponding first slide 35, the second slide 36, the third slide 37, and the fourth slide 38 to move and separate from the product. In the process of the ejector 6 pushing the product to separate from the movable mold assembly 2, it only needs to overcome the clamping force between the bottom surface of the product and the movable mold assembly 2, making the process of the product leaving the die-casting mold faster and more stable.

[0061] The ejector 6 of this solution includes a top plate 61 that moves on the movable mold assembly 2, and a push rod 62 inserted on the top plate 61. The end of the push rod 62 away from the top plate 61 is movably inserted in the movable mold assembly 2 and movably abuts against the product.

[0062] The die-casting machine's ejector structure is connected to ejector plate 61. After the product is formed, the fixed die assembly 1 separates from the movable die assembly 2, and the sliding assembly 3 separates from the product. The die-casting machine's ejector structure then moves ejector plate 61, which in turn moves ejector pin 62. Ejector pin 62 abuts against the bottom surface of the product and applies a thrust to the product. This thrust overcomes the clamping force between the product and movable die assembly 2, allowing ejector pin 62 to move the product and separate it from movable die assembly 2.

[0063] The valve stem 52 of this solution is provided with a first abutment surface 521, and the fixed block 86 is provided with a second abutment surface 861. The first abutment surface 521 and the second abutment surface 861 are movably abutted against each other, and the gas channel 51 can be disconnected from the product cavity 4 due to the abutment between the first abutment surface 521 and the second abutment surface 861.

[0064] When the vacuum element 5 has finished extracting the air from the product cavity 4, the driving element 53 drives the valve stem 52 to move, so that the valve stem 52 abuts against the fixed mold assembly 1, and the first abutting surface 521 abuts against the second abutting surface 861. The gas channel 51 is disconnected from the product cavity 4 to prevent the molten metal from entering the gas channel 51 when being injected into the product cavity 4, causing the gas channel 51 to be blocked.

[0065] A vacuum element 5 is provided to extract air from the product cavity 4 and expel it to the outside through the gas passage 51. Subsequently, the valve stem 52 is moved to disconnect the product cavity 4 from the gas passage 51, maintaining a negative pressure in the product cavity 4. This way, when molten metal is injected into the product cavity 4, the air incorporated into the molten metal remains within the designed range, preventing the formation of numerous pores within the molded product. This prevents a reduction in the product's density and strength, and ensures that the product's mechanical properties are not affected.
