Description

Technical Field

[0001] The invention relates to the technical field of die casting processing, and in particular to a die casting device and a die casting method for automobile die castings. Background Art

[0002] Die casting, as one of the metal casting processes, uses high pressure to inject molten metal into the mold cavity. It is known for its ability to quickly produce high-precision and complex-shaped castings. There are many die-castings for automotive parts. For example, during the die-casting process of automotive brake calipers, due to the arc-shaped shape of the brake calipers, molten metal is generally injected into a pre-set mold cavity under high pressure through a die-casting device to form the desired casting. Due to the bubbles and inclusions generated inside the die-casting during the die-casting process, in order to ensure its die-casting quality, the time that the die-casting stays in the mold is generally increased, which can reduce the porosity and cracking in the casting. However, if the die-casting stays in the mold for too long, it may result in a long downtime for each mold change, increasing the time required for die-casting production and reducing the production efficiency of the device for die-castings. Summary of the invention

[0003] The object of the present invention is to provide a die-casting device and a die-casting method for automotive die-casting parts. By setting a rotation component, multiple die-casting molds can be rotated in a mounting frame and a die-casting table, so that when one die-casting mold is in use, another die-casting mold can be sufficiently cooled, which can effectively reduce the downtime caused by mold replacement, reduce the time required for die-casting production, and improve the production efficiency of the device for die-casting parts, so as to solve the above-mentioned deficiencies in the technology.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a die-casting device and a die-casting method for automobile die-casting parts, comprising: A die-casting table and a plurality of die-casting dies, wherein a die-casting machine is installed at one end of the die-casting table, and the die-casting machine is used to inject molten metal into the plurality of die-casting dies; A rotation assembly is used to drive multiple die-casting molds to rotate on the die-casting table and move multiple die-casting molds to the bottom of the column die-casting machine. The rotation assembly includes a mounting frame installed on the top of the die-casting table and communicating with the inside of the die-casting table, two discharge troughs symmetrically arranged on the top of the mounting frame and communicating with the inside of the die-casting table for the die-casting molds to slide, and a connecting ring rotatably installed in the die-casting table, and a first stabilizing ring is installed in the die-casting table, a swing arm is installed on the outside of the connecting ring, and the swing arm is slidably connected to the first stabilizing ring, an intermittent assembly for driving the connecting ring to rotate is provided in the die-casting table, and a lifting and lowering assembly cooperating with the first stabilizing ring is provided in the die-casting table, and the rotating assembly is used to rotate the connecting ring. The die-casting mold is guided to slide along the first stabilizing ring and pushed to slide out or in the die-casting table. A knocking assembly is provided in the die-casting table to cooperate with the lifting and lowering assembly, and the knocking assembly is used to knock the die-casting mold that is rotated and slid out; and the mounting frame has a covering effect on the die-casting table, so that when the die-casting mold slides into one of the discharge troughs, it is covered in the mounting frame and the die-casting table, which can prevent the die-casting mold from getting into a dangerous situation with the operator due to excessive temperature when moving. The setting of multiple die-casting molds and the reasonable scheduling of the use frequency and sequence of each mold can effectively reduce the downtime caused by mold replacement.

[0005] Preferably, the intermittent component includes an intermittent column installed between the die-casting table and the connecting ring, a plurality of intermittent frames fixed on the outside of the intermittent column, and a first servo motor fixed in the die-casting table, the output end of the first servo motor is sleeved with an intermittent swing arm, one end of the intermittent swing arm is installed with an intermittent swing column, and the plurality of intermittent frames are provided with intermittent grooves for the intermittent swing columns to slide, and a thorn component for stabilizing the intermittent column is provided in the die-casting table; and the intermittent groove is a U-shaped structure, so that the intermittent swing column slides into the intermittent groove and moves along the guide in the intermittent groove, and then pushes the intermittent frame to drive the intermittent column to rotate, so that the plurality of intermittent frames are rotated, so that the plurality of die-casting molds are rotated along the die-casting table under the action of the rotation component, and the number of intermittent frames is equal to the number of die-casting molds, so that each die-casting mold can be rotated synchronously after each intermittent frame rotates. Movement makes it easy for multiple die-casting molds to move stably and move and reset, and then multiple die-casting molds are rotated with each other, so there are appropriate working intervals between each other, and the molds are rotated and replaced alternately, so that when one mold is in use, another mold can be given enough cooling and maintenance time, so that the casting can be cooled more evenly in the mold, reducing internal stress and deformation, thereby avoiding mold deformation and damage caused by continuous high temperature, and avoiding a certain mold from being subjected to high-intensity pressure for a long time, thereby extending its service life. At the same time, multiple die-casting molds can be operated inside and outside the die-casting table, thereby improving the flexibility of die-casting production. During the production process, the mold may be accidentally damaged or malfunction. If it is not handled in time, it will cause the entire production line to shut down. Through the alternating rotation of the die-casting mold, it can be switched immediately when a mold abnormality is found to ensure uninterrupted production.

[0006] Preferably, the thorn assembly includes a fixing ring fixed to the inner bottom wall of the die-casting table and a ratchet wheel sleeved on the outside of the intermittent column, and the ratchet wheel is located in the fixing ring, and a thorn claw matching the ratchet wheel is installed in the fixing ring; and one side of the thorn claw contacts the outside of the ratchet wheel, so that the outside of the ratchet wheel rotates in one direction along the side of the thorn claw. When the ratchet wheel rotates in the opposite direction along the thorn claw, one side of the thorn claw conflicts with the outside of the ratchet wheel, so that the ratchet wheel can only move in one direction along the side of the thorn claw, thereby preventing the intermittent column from reversing and ensuring the stable rotation of the intermittent column.

[0007] Preferably, the landing assembly includes a second stabilizing ring fixed in the die-casting table and a guide frame installed at one end of the swing arm, a guide groove for the guide frame to slide is formed between the second stabilizing ring and the first stabilizing ring, two symmetrical landing blocks are installed at the bottom end of the die-casting mold, two landing gears for the two landing blocks to slide are symmetrically installed on the first stabilizing ring and the second stabilizing ring, and a reset assembly for lifting the die-casting mold is provided on the guide frame; and the top arch surface of the landing gear cooperates with the arch degree of the arch surface of the landing block, so that the landing block slides along the second stabilizing ring and the first stabilizing ring toward the top of the landing gear, so that the landing block continuously moves upward along the landing gear, pushing the die-casting mold to slide into the discharge chute along between the die-casting table and the mounting frame and lift the die-casting mold upward in the discharge chute, so that the die-casting mold can be exposed to the outside of the die-casting table, so that the die-casting mold and the die-casting machine can more easily enter the processing area, thereby improving the processing efficiency of the casting.

[0008] Preferably, the reset assembly includes a reset column fixed on the top of the guide frame and a sleeve installed on the bottom end of the die-casting mold, and the sleeve is slidably sleeved on the outside of the reset column, and a spring groove is opened on the top of the reset column, and a spring is installed between the spring groove and the sleeve; and under the action of the spring's own elastic force, the sleeve can be moved along the outside of the reset column to reset, so that the die-casting mold moves slowly along the discharge chute into the mounting frame and the die-casting table, avoiding mutual interference between the die-casting mold and the mounting frame and the die-casting table when moving, thereby ensuring stable movement of the die-casting mold.

[0009] Preferably, the die-casting table is provided with a knocking groove, a sliding rod slidably installed in the knocking groove, and a knocking plate fixed on the top of the sliding rod, and the knocking plate is located above the landing gear, one side of the knocking plate is in contact with the outside of the die-casting mold, and a rotating component for driving the sliding rod to move back and forth is provided in the knocking groove; the outside of the die-casting mold can be auxiliary knocked, and since the shape of the die-casting in the die-casting mold is an arc-shaped geometry, the bent part of the die-casting is in contact with and adsorbed in the die-casting mold and is not easy to peel off, and under the accurate knocking of the knocking plate and the outside of the die-casting mold, the die-casting can be helped to peel off the sticky part in the die-casting mold in time, ensuring that the die-casting meets the production requirements.

[0010] Preferably, the rotating assembly includes a second servo motor fixed in the knocking groove, a push rod installed at the bottom end of the sliding rod, and a rotating disk fixed at the top end of the second servo motor, a push column is installed at the top end of the rotating disk, and the push rod is provided with an annular groove for the push column to slide.

[0011] A die-casting method of a die-casting device for an automobile die-casting part comprises the following steps: S1. The sliding rod is driven by the rotating assembly to reciprocate along the knocking groove, so that the movement of the sliding rod drives the knocking plate to reciprocate with the outside of the die-casting mold, so that the knocking plate and the outside of the die-casting mold are reciprocatedly knocked, so as to facilitate the removal of the die-casting in the die-casting mold; S2. At this time, the intermittent component rotates to drive the swing arm to rotate around the bottom of the first stable ring, so that the swing arm rotates to drive the guide frame to slide along the guide groove, and the multiple die-casting molds rotate around the first stable ring and the second stable ring, so that the positions of the multiple die-casting molds in the mounting frame and the die-casting table are changed and rotated, so that when one die-casting mold is in use, another die-casting mold can be given enough cooling and maintenance time, so that the casting can be cooled more evenly in the die-casting mold; S3, and through the rotation of the thorn assembly, the ratchet wheel can only move in one direction along one side of the thorn claw, thereby preventing the intermittent column from reversing and ensuring the stable rotation of the intermittent column; S4. As the guide frame moves along the guide groove, the two landing blocks slide along the first stabilizing ring and the second stabilizing ring toward the two landing gears, so that the landing blocks continuously slide upward along the landing gears, so that the sleeve slides upward along the outside of the reset column, and the spring is stretched inside the sleeve, so that the die-casting mold can be guided and moved in the mounting frame and the die-casting table, avoiding mutual interference between the die-casting mold and the mounting frame and the die-casting table when the die-casting mold moves, and ensuring stable movement of the die-casting mold; S5. Then the die-casting mold slides along the mounting frame and the die-casting table toward the discharge trough, and is driven into the discharge trough and lifted upward in the discharge trough under the continuous lifting of the lifting block. Then the die-casting mold and the die-casting machine can more easily enter the processing area, and the die-casting machine injects the molten metal inside into the die-casting mold, thereby improving the processing efficiency of the casting.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are: 1. By setting up the rotation assembly, multiple die-casting molds can be rotated in the mounting frame and the die-casting table, so that one die-casting mold can be sufficiently cooled while another die-casting mold is in use, which can effectively reduce the downtime caused by mold replacement, reduce the time required for die-casting production, and improve the production efficiency of the device for die-castings.

[0013] 2. Through the setting of two discharge troughs, the die-casting mold can be slowly placed in the discharge trough, which is conducive to the die-casting or die-casting removal of the die-casting mold. The die-casting mold is exposed to the outside of the die-casting table under the action of the discharge trough. When the die-casting mold is found to be abnormal, it can be switched immediately to ensure uninterrupted production.

[0014] 3. Through the setting of the landing gear and the landing block, the landing block can be driven to move upward along the landing gear, and then the die-casting mold is pushed to slide into the discharge chute between the die-casting table and the mounting frame and the die-casting mold is lifted upward in the discharge chute, so that the die-casting mold can be exposed to the outside of the die-casting table, so that the die-casting mold and the die-casting machine can more easily enter the processing area, thereby improving the processing efficiency of the casting.

[0015] 4. Through the setting of the knocking component, the outside of the die-casting mold can be assisted by knocking. Accurate knocking between the knocking plate and the outside of the die-casting mold can help the die-casting parts to be peeled off the sticking parts in the die-casting mold in time, ensuring that the die-casting parts meet the production requirements.

[0016] 5. By setting the thorn assembly, the ratchet wheel can only move in one direction along one side of the thorn claw, thereby preventing the intermittent column from reversing, ensuring the stable rotation of the intermittent column, and allowing the die-casting mold to move stably in the mounting frame and the die-casting table.

[0017] 6. Through the setting of the spring, the sleeve can be reset along the outside of the reset column under the action of the spring's own elastic force, so that the die-casting mold can slowly move along the discharge chute into the mounting frame and the die-casting table, avoiding mutual interference between the die-casting mold and the mounting frame and the die-casting table when moving, ensuring stable movement of the die-casting mold.

[0024] The landing assembly 3 includes a second stabilizing ring 31 fixed in the die-casting table 1 and a guide frame 32 installed at one end of the swing arm 25, a guide groove 33 for the guide frame 32 to slide is formed between the second stabilizing ring 31 and the first stabilizing ring 24, two symmetrical landing blocks 35 are installed at the bottom end of the die-casting mold 12, and two landing gears 34 for the two landing blocks 35 to slide are symmetrically installed on the first stabilizing ring 24 and the second stabilizing ring 31, and a reset assembly 4 for lifting the die-casting mold 12 is provided on the guide frame 32; the reset assembly 4 includes a reset column 42 fixed at the top of the guide frame 32 and a sleeve 41 installed at the bottom end of the die-casting mold 12, and the sleeve 41 is slidably sleeved on the outside of the reset column 42, a spring groove 43 is opened at the top of the reset column 42, and a spring 44 is installed between the spring groove 43 and the sleeve 41.

[0025] When the die-casting mold 12 rotates, the intermittent swing arm 56 is driven by the first servo motor 54 to rotate, and then the intermittent swing arm 56 rotates to drive the intermittent swing column 55 to rotate and move into one of the intermittent slots 53. At this time, the intermittent swing arm 56 continues to rotate to drive the intermittent swing column 55 to slide along one of the intermittent slots 53 and push one of the intermittent frames 52 to rotate. The rotation of one of the intermittent frames 52 drives the intermittent column 51 to rotate, so that the other intermittent frame 52 rotates on the intermittent column 51, and the rotation of the intermittent column 51 drives the connecting ring 23 and the ratchet wheel 57 to rotate, and the ratchet wheel 57 rotates to move it along the fixed The ring 59 rotates, so that the ratchet wheel 57 and the thorn claw 58 slide and rotate, which is conducive to the stable rotation of the intermittent column 51, and the connecting ring 23 rotates to drive the swing arm 25 to rotate around the bottom of the first stable ring 24, so that the swing arm 25 rotates to drive the guide frame 32 to rotate along the guide groove 33, and the rotation of the guide frame 32 drives the die-casting mold 12 to slide along the discharge chute 22. As the guide frame 32 moves, the landing block 35 slides downward along one of the landing gears 34, so that the spring 44 itself shrinks and pulls the sleeve 41 to slide downward along the outside of the reset column 42, and the sleeve 41 moves downward to pull the die-casting mold 12 moves downward along the discharge chute 22, and then the top of the die-casting mold 12 matches the internal slope of the mounting frame 21, and the die-casting mold 12 slides in the discharge chute 22 toward the mounting frame 21 and the die-casting table 1, and then the movement of the die-casting mold 12 is rotated with another die-casting mold 12, so that when one die-casting mold 12 is in use, the other die-casting mold 12 can be sufficiently cooled, which can effectively reduce the downtime caused by mold replacement and reduce the time required for die-casting production. Similarly, when another die-casting mold 12 is moving; and when another die-casting mold 12 is moving, the top arch surface of the landing gear 34 is in contact with the landing gear 34. The arch of the block 35 is matched so that the landing block 35 slides along the second stabilizing ring 31 and the first stabilizing ring 24 to the top of the other landing gear 34, so that the landing block 35 continuously moves upward along the other landing gear 34, pushing the die-casting mold 12 to slide into the discharge chute 22 along between the die-casting table 1 and the mounting frame 21 and lift the die-casting mold 12 upward in the discharge chute 22, so that the die-casting mold 12 can be exposed to the outside of the die-casting table 1, so that the die-casting mold 12 can more easily enter the processing area with the die-casting machine 11, and the die-casting machine 11 injects the molten metal inside into the die-casting mold 12, thereby improving the processing efficiency of the casting.

At this time, the intermittent component 5 rotates to drive the swing arm 25 to rotate around the bottom of the first stable ring 24, so that the swing arm 25 rotates to drive the guide frame 32 to slide along the guide groove 33, and the multiple die-casting molds 12 rotate around the first stable ring 24 and the second stable ring 31, so that the positions of the multiple die-casting molds 12 in the mounting frame 21 and the die-casting table 1 are changed and rotated, and when one die-casting mold 12 is in use, the other die-casting mold 12 can be given enough cooling and maintenance time, so that the casting can be cooled more evenly in the die-casting mold 12; S3, and through the rotation of the thorn assembly, the ratchet wheel 57 can only move in one direction along one side of the thorn claw 58, thereby preventing the intermittent column 51 from reversing and ensuring the stable rotation of the intermittent column 51; S4, as the guide frame 32 moves along the guide groove 33, the two landing blocks 35 slide along the first stabilizing ring 24 and the second stabilizing ring 31 toward the two landing gears 34, so that the landing blocks 35 continuously slide upward along the landing gears 34, so that the sleeve 41 slides upward along the outside of the reset column 42, and the spring 44 is stretched inside the sleeve, so that the die-casting mold 12 can be guided and moved in the mounting frame 21 and the die-casting table 1, avoiding mutual interference between the die-casting mold 12 and the mounting frame 21 and the die-casting table 1 when the die-casting mold 12 moves, and ensuring stable movement of the die-casting mold 12; S5. Then, the die-casting mold 12 slides along the mounting frame 21 and the die-casting table 1 toward the discharge chute 22, and is driven into the discharge chute 22 and lifted upward in the discharge chute 22 under the continuous lifting of the lifting block 35. Then, the die-casting mold 12 and the die-casting machine 11 can more easily enter the processing area, and the die-casting machine 11 injects the molten metal inside into the die-casting mold 12, thereby improving the processing efficiency of the casting.
