Description

Technical Field

[0001] The invention relates to the technical field of motor housing die-casting, and in particular to a generator housing die-casting processing clamping device and method thereof. Background Art

[0002] Die-casting technology is a metal casting process characterized by using the inner cavity of the mold to apply high pressure to the molten metal. This process is similar to injection molding, in which the mold is usually made of a higher-strength alloy. The motor housing is usually made of an aluminum alloy. Before die-casting, the molten aluminum liquid needs to be poured into the outer mold and then the inner mold is inserted into the outer mold through a hydraulic system for die-casting. During this process, the aluminum liquid is easy to overflow and adhere to the device, making the device difficult to clean and causing waste of aluminum liquid.

[0003] Patent No. CN221109839U discloses a clamping device for die-casting processing of generator housing. The patent has a protective structure, and two groups of clamping blocks are provided, which are symmetrically fixed on the top of the fixed block. The fixing block can be limited at the bottom of the clamping block through the clamping structure of the clamping groove and the clamping block. The fixing block is provided with two groups, which are symmetrically limited at the top of the base. The clamping block and the die-casting are protected by the protective pad, so that the clamping device has a protective effect when the generator housing is die-casted to avoid friction and anti-slip structure. The clamping block is provided with two groups, which are symmetrically fixed on the top of the connecting block. The inner parts of the two ends of the mounting block and the inner parts of the two ends of the clamping block are A threaded groove is provided on the part, which is matched with the bolt. The clamping block is clamped in the interior of the mounting block, so that the bolt is screwed in the threaded groove, so that the clamping block is limited and fixed in the interior of the mounting block, and the connecting block is fixed to the bottom end of the base. The friction of the bottom end of the base is enhanced by the anti-skid pad, so that the generator housing die-casting processing clamping device has a better anti-skid effect when in use, making the device more stable to use. Although this patent solves the above problems, it still has the problem that the overflowed aluminum liquid cannot be collected during die-casting, resulting in waste of aluminum liquid and difficulty in cleaning the device. Therefore, a generator housing die-casting processing clamping device and method thereof are proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a generator housing die-casting processing clamping device and method thereof in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a generator housing die-casting processing clamping device, including a positive half mold, side half molds are arranged on both sides of the positive half mold, a die-casting box is arranged on the outside of the side half mold, the bottom surface of the die-casting box is fixedly connected with a drainage cylinder, the bottom end of the drainage cylinder is fixedly connected with a liquid storage tank, the two sides of the liquid storage tank are hinged with box doors, the upper surface of the liquid storage tank is fixedly connected with a support column, the upper surface of the liquid storage tank is fixedly connected with a double-motor linear motor, the inner surface of the double-motor linear motor is slidably connected with a slide groove push rod, the inner surface of the slide groove push rod is slidably connected with a transmission slide rod, The circumferential surface of the transmission slide rod is fixedly connected with a lower limit ring, the bottom end of the circumferential surface of the transmission slide rod is clamped with a push rod, the lower surface of the push rod is fixedly connected with a first sliding shaft, the bottom end of the first sliding shaft is fixedly connected with a push plate, the bottom surface of the inner wall of the liquid storage tank is fixedly connected with a trapezoidal base, the top surface of the liquid storage tank is provided with a slide groove, and a mold adjustment device for moving and adjusting molds of different sizes is arranged above the liquid storage tank. A liquid injection protection device for preventing aluminum liquid from splashing around when filling aluminum liquid is arranged above the liquid storage tank. The top end of the support column is fixedly connected to the bottom surface of the die-casting box, and the first sliding shaft and the inner surface of the slide groove are The upper surface of the push plate and the upper surface of the trapezoidal base are in contact with each other, the upper surface of the lower limit ring and the lower surface of the slide push rod are in contact with each other, and the lower surface of the lower limit ring and the upper surface of the push rod are in contact with each other. The front and rear positive half molds and the left and right side half molds are fitted together, and then the aluminum liquid is poured between the four half molds. When the aluminum liquid is sandwiched between the four half molds, the inner mold is pressed down and inserted between the four half molds through an external hydraulic device, so that the aluminum liquid forms a shape of a motor housing, and waits for cooling and forming before taking it out. When the inner mold squeezes the aluminum liquid, the aluminum liquid rises to form a housing, and part of the aluminum liquid overflows and is caught by the die casting box, and then The aluminum liquid flows into the liquid storage tank through the discharge cylinder and is collected, and the double-acting linear motor is started. The double-acting linear motor drives the slide push rod to move from the lower corner of the die-casting box to the center. When the slide push rod moves, the force is transmitted to the push rod through the transmission slide rod, and the push rod slides in the slide groove one through the first slide shaft. The double-acting linear motor drives the slide push rod to move back and forth, thereby driving the push rod and the first slide shaft to slide back and forth in the slide groove one. The first slide shaft then drives the push plate to slide back and forth on the trapezoidal base to move the aluminum liquid that falls on the trapezoidal base to the two sides of the trapezoidal base. The aluminum liquid that moves to the two sides of the trapezoidal base contacts its inclined surface and then flows to the two ends of the trapezoidal base and is blocked by the box door.

The positive half mold and the side half mold are limited by the adjusting slide bar to make themselves more stable when sliding, and the transmission plate drives the four adjusting slide bars through four connecting rings to push the positive half mold and the side half mold at the same time. When the pressure on the positive half mold and the side half mold is too large or they are hit by foreign objects and cause themselves to vibrate, the vibration force is transmitted from the positive half mold and the side half mold to the adjusting slide bar, so that the adjusting slide bar slides slightly and generates friction with the friction sleeve shaft to reduce the vibration, so as to avoid the force on the positive half mold and the side half mold cannot be released and cause damage to the mold, the positive half mold and the side half mold are quickly removed from the adjusting slide bar through the clamping shaft to replace molds of different sizes, and then the mold is driven to move in the die-casting box through the adjusting slide bar.

[0007] Preferably, the liquid injection protection device includes a fixed plate, a slide rail, an elastic telescopic rod, an arc-shaped baffle, and a second slide shaft. The fixed plate is fixedly connected to both sides of the top surface of the die-casting box, the slide rail is fixedly connected to one side of the fixed plate close to the side half-mold, the elastic telescopic rod is fixedly connected to one side of the fixed plate close to the side half-mold, the arc-shaped baffle is fixedly connected to one end of the elastic telescopic rod away from the fixed plate, and the second slide shaft is fixedly connected to the bottom surface of the arc-shaped baffle. The liquid injection protection device also includes a transmission connecting rod, a push block, a slot block, a reset spring rod, a transmission slider, a convex plate, and a contact shaft. The transmission connecting rod is fixedly connected The push block is fixedly connected to the top of the transmission connecting rod, the slot block is fixedly connected to the end of the push block close to the side half mold, the reset spring rod is fixedly connected to the bottom surface of the inner wall of the slot block, the transmission slide block is fixedly connected to the top of the reset spring rod, the two convex plates are fixedly connected to the side of the arc baffle close to the fixed plate, the abutment shaft is fixedly connected between the two convex plates, the second sliding shaft is slidably connected to the inner surface of the slide rail, the bottom surface of the arc baffle and the upper surface of the slide rail are in contact with each other, the push block and the upper surface of the die casting box are in contact with each other, the transmission slide block and the inner wall of the slot block slide The arc surface of the transmission slider and the circumferential surface of the conflicting shaft are in contact with each other, and the arc baffle can slide in the slide rail through the second sliding shaft to push the left and right arc baffles to approach and fit each other. At this time, the aluminum liquid is injected into the mold, and the aluminum liquid splashing around is blocked by the arc baffle. When the connecting block approaches the die-casting box, the driving block is driven to approach the side half mold through the transmission connecting rod, and the driving block drives the transmission slider to approach the side half mold. When the transmission slider moves, the arc baffle is pushed to move through the conflicting shaft and the convex plate, so that when the injection is completed and the die-casting starts, the driving block moves to the side away from the die-casting box, thereby driving the card slot block and the transmission The slider moves to the side away from the die-casting box. At this time, the resistance shaft loses the resistance of the transmission slider, and the elastic telescopic rod drives the arc baffle to slide to both sides of the die-casting box instantly to prevent the arc baffle from affecting the downward pressure of the mold. When the transmission slider moves to the side away from the die-casting box and contacts the resistance shaft again, the transmission slider slides downward into the slot block and crosses the resistance shaft after being pressed. At this time, the elastic reset effect of the reset spring rod drives the transmission slider to rise and reset, so that the transmission slider can push the arc baffle closer to the side half mold again, so that the device can automatically block the aluminum liquid during liquid injection, and automatically stay away from the die-casting range when die-casting is required.

[0008] A method for using a generator housing die-casting clamping device, comprising the following steps:

[0009] Step 1: First, the positive half mold and the side half mold are pushed to move in the die casting box by adjusting the sliding rod, and finally merged into an outer mold by approaching each other;

[0010] Step 2: Then, heat the aluminum alloy material to the melting point to obtain liquid aluminum, and then pour the molten aluminum into the pre-prepared outer mold. During the pouring process, it is necessary to control the temperature and pouring speed of the aluminum liquid to ensure that the aluminum liquid fully fills the mold and avoids the generation of bubbles and defects;

[0011] Step 3: Then, start the hydraulic device to drive the inner mold to press down and insert it into the outer mold. The downward pressure of the inner mold causes the aluminum liquid in the outer mold to rise and form the motor housing. After the aluminum liquid fully fills the mold, wait for a while to allow the aluminum liquid to cool and solidify;

[0012] Step 4: Finally, when the aluminum liquid cools and solidifies, start the hydraulic device to drive the inner mold to rise, open the positive half mold and the side half mold, take out the formed aluminum casting, and perform necessary finishing and processing, such as drilling, milling, polishing, sandblasting, etc., to meet the accuracy and functional requirements of the shell, and then paint as needed to complete the casting of the motor housing.

[0015] 2. The generator housing die-casting clamping device and method thereof, the positive half mold and the side half mold are limited by the adjusting slide bar to make themselves more stable when sliding and merge more accurately, thereby avoiding the positive half mold and the side half mold from shifting during the merging process, resulting in unqualified die-cast products of the motor housing.

The device can automatically block the aluminum liquid during liquid injection, and automatically stay away from the die-casting range when die-casting is required, which not only improves the protection effect but also improves the convenience of use.

[0027] Working principle: fit the front and rear positive half molds 1 and the left and right side half molds 2 together, then pour the molten aluminum between the four half molds. When the molten aluminum is sandwiched between the four half molds, the inner mold is pressed down and inserted between the four half molds through an external hydraulic device, so that the molten aluminum forms a shape of a motor housing, and waits for cooling and forming before taking it out. When the inner mold squeezes the molten aluminum, the molten aluminum rises to form a housing, and part of the molten aluminum overflows and is caught by the die casting box 3.

[0028] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, the mold adjusting device 5 includes a clamping shaft 51, an adjusting slide bar 52, and a friction sleeve shaft 53. The clamping shaft 51 is fixedly connected to the side of the positive half mold 1 close to the die casting box 3, the adjusting slide bar 52 is clamped on the inner surface of the clamping shaft 51, and the friction sleeve shaft 53 is fixedly connected to the inner surface of the die casting box 3. The positive half mold 1 and the side half mold 2 are limited by the adjusting slide bar 52 to make themselves more stable when sliding, and the merging is more accurate, thereby avoiding the displacement of the positive half mold 1 and the side half mold 2 during the merging process, resulting in the die casting product of the motor housing being unqualified. The mold adjusting device 5 also includes a connecting ring 54, a transmission plate 55, a connecting block 56, an upper limit ring 57, and a slide groove support plate 58. The connecting ring 54 is clamped on the circumferential surface of the adjusting slide bar 52, the transmission plate 55 is fixedly connected to the circumferential surface of the connecting ring 54, and the connecting block 56 is fixedly connected to the side of the transmission plate 55 away from the die-casting box 3, the upper limit ring 57 is fixedly connected to the circumferential surface of the transmission slide bar 42, the slide groove support plate 58 is fixedly connected to the outer surface of the die-casting box 3, the clamping shaft 51 and the side half mold 2 close to the die-casting box 3 are fixedly connected, the adjusting slide bar 52 and the inner surface of the friction sleeve shaft 53 are slidably connected, the transmission slide bar 42 and the inner surface of the slide groove support plate 58 are slidably connected, the lower surface of the upper limit ring 57 and the upper surface of the slide groove support plate 58 are in contact with each other, the top of the transmission slide bar 42 and the bottom end of the connecting block 56 are fixedly connected, the positive half mold 1 and the side half mold 2 are quickly removed from the adjusting slide bar 52 through the clamping shaft 51 to replace molds of different sizes, and then the mold is driven to move in the die-casting box 3 by the adjusting slide bar 52, so that motor housings of different sizes can be die-cast, thereby improving the applicability of the device.

[0029] Working principle: the transmission slide bar 42 slides in the slide groove support plate 58 and drives the transmission plate 55 to approach the die-casting box 3 through the connecting block 56. The transmission plate 55 drives the adjusting slide bar 52 to slide in the friction sleeve shaft 53 and approach the center of the die-casting box 3 through the connecting ring 54. The adjusting slide bar 52 drives the positive half mold 1 and the side half mold 2 to approach each other through the clamping shaft 51. The positive half mold 1 and the side half mold 2 are limited by the adjusting slide bar 52 to make their own sliding more stable and the merging more precise, avoiding the displacement of the positive half mold 1 and the side half mold 2 during the merging process, resulting in the die-casting product of the motor housing being unqualified.

The stability during movement ensures the accuracy of the merging. When the positive mold half 1 and the side mold half 2 are subjected to excessive pressure or are hit by external objects and vibrate themselves, the vibration force is transmitted from the positive mold half 1 and the side mold half 2 to the adjusting slide bar 52, causing the adjusting slide bar 52 to slide slightly and generate friction with the friction sleeve shaft 53 to reduce the vibration, thereby preventing the force on the positive mold half 1 and the side mold half 2 from being unable to be released and causing damage to the mold, thereby improving the service life of the positive mold half 1 and the side mold half 2. The positive mold half 1 and the side mold half 2 can be quickly removed from the adjusting slide bar 52 through the clamping shaft 51 to replace molds of different sizes, and then the mold is driven to move in the die-casting box 3 through the adjusting slide bar 52, so that motor housings of different sizes can be die-cast, thereby improving the applicability of the device.

[0030] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, the liquid injection protection device 6 includes a fixed plate 61, a slide rail 62, an elastic telescopic rod 63, an arc baffle 64, and a second slide shaft 65. The fixed plate 61 is fixedly connected to both sides of the top surface of the die-casting box 3, the slide rail 62 is fixedly connected to one side of the fixed plate 61 close to the side half mold 2, the elastic telescopic rod 63 is fixedly connected to one side of the fixed plate 61 close to the side half mold 2, the arc baffle 64 is fixedly connected to one end of the elastic telescopic rod 63 away from the fixed plate 61, and the second slide shaft 65 is fixedly connected to the bottom surface of the arc baffle 64. The two arc baffles 64 are close to and fit each other. At this time, the aluminum liquid is injected into the mold, and the aluminum liquid splashing around is blocked by the arc baffle 64, so as to prevent the aluminum liquid from splashing and causing waste and difficulty in cleaning, and also avoid the overheated aluminum liquid splashing to the staff to cause harm, thereby improving the operational safety of the device. The liquid injection protection device 6 also includes a transmission connecting rod 66, a pushing block 67, a slot block 68, a reset spring rod 69, and a transmission slider 61 0, convex plate 611, abutment shaft 612, transmission connecting rod 66 is fixedly connected to the top of connecting block 56, pushing block 67 is fixedly connected to the top of transmission connecting rod 66, slot block 68 is fixedly connected to the end of pushing block 67 close to side half mold 2, reset spring rod 69 is fixedly connected to the bottom surface of the inner wall of slot block 68, transmission slide block 610 is fixedly connected to the top of reset spring rod 69, two convex plates 611 are fixedly connected to one side of arc baffle 64 close to fixed plate 61, abutment shaft 612 is fixedly connected to the two Between the convex plates 611, the second sliding shaft 65 and the inner surface of the sliding rail 62 are slidably connected, the bottom surface of the arc-shaped baffle plate 64 and the upper surface of the sliding rail 62 are in contact with each other, the pushing block 67 and the upper surface of the die-casting box 3 are in contact with each other, the transmission slider 610 and the inner wall of the slot block 68 are slidably connected, the arc surface of the transmission slider 610 and the circumferential surface of the abutment shaft 612 are in contact with each other, the device can automatically block the aluminum liquid during liquid injection, and automatically stay away from the die-casting range when die-casting is required, which not only improves the protection effect but also improves the convenience of use.

[0031] Working principle: the arc baffle 64 can slide in the slide rail 62 through the second slide shaft 65, pushing the left and right arc baffles 64 to approach and fit each other. At this time, the aluminum liquid is injected into the mold, and the aluminum liquid splashing around is blocked by the arc baffle 64, preventing the aluminum liquid from splashing around and causing waste and difficulty in cleaning, and also avoiding the overheated aluminum liquid from splashing on the staff to cause harm, thereby improving the operational safety of the device. When the connecting block 56 approaches the die-casting box 3, the driving block 67 is driven to approach the side half mold 2 through the transmission connecting rod 66, and the driving block 67 drives the transmission slider 610 to approach the side half mold 2. When the transmission slider 610 moves, it pushes the arc baffle 64 to move through the friction shaft 612 and the convex plate 611, so that when the injection is completed and the die casting starts, the pushing block 67 moves to the side away from the die-casting box 3, thereby driving the card slot block 6 8 and the transmission slide block 610 move to the side away from the die-casting box 3. At this time, the resistance shaft 612 loses the resistance of the transmission slide block 610, and the elastic telescopic rod 63 drives the arc baffle 64 to slide to both sides of the die-casting box 3 instantly to prevent the arc baffle 64 from affecting the downward pressure of the mold. When the transmission slide block 610 moves to the side away from the die-casting box 3 and contacts the resistance shaft 612 again, the transmission slide block 610 slides downward into the card slot block 68 and passes over the resistance shaft 612 after being pressed. At this time, the elastic reset effect of the reset spring rod 69 drives the transmission slide block 610 to rise and reset, so that the transmission slide block 610 can push the arc baffle 64 to approach the side half mold 2 again, so that the device can automatically block the aluminum liquid during liquid injection, and automatically stay away from the die-casting range when die-casting is required, which not only improves the protection effect but also improves the convenience of use.
