Description

Technical Field

[0001] The present invention relates to the field of casting technology, and more specifically, it relates to a casting machine for generator end covers. Background Art

[0002] In the casting process of generator end covers, as a key device, the performance and safety of the casting machine are crucial. In traditional casting machines for generator end covers, the method of pushing molten metal for feeding is usually adopted by a piston. However, in this feeding method, when the molten metal is extruded by the piston, relatively large pressure and impact force are often generated. Since the feeding port of the casting machine is often designed to be relatively open and lacks sufficient shielding and protection measures, it leads to the molten metal being easily splashed out from the feeding port when being extruded.

[0003] The splashing of molten metal not only causes damage to the equipment structure of the casting machine itself, such as corrosion and wear, reducing the service life of the equipment; more importantly, the splashed high-temperature molten metal may also cause serious burns or even more serious injuries to the operators, posing a great threat to production safety. To solve the above problems, a casting machine for generator end covers is proposed. Summary of the Invention

[0045] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0046] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present invention.

[0047] Embodiment, please refer to Figure 1 -Figure 10 , a generator end cover casting machine, including a casting machine body 1, and a feeding mechanism 2 communicated with the mold is arranged on the casting machine body 1;

[0048] The feeding mechanism 2 includes a feeding component 3 communicated with the mold, and also includes a feeding hopper 4 arranged on the feeding component 3, and a covering sleeve 5 arranged on the feeding component 3;

[0049] The feeding component 3 includes a molten metal feeding pipe 301 communicated with the mold, and also includes a feeding port 302 opened at one end of the molten metal feeding pipe 301 away from the mold, and a driving member 6 arranged in the molten metal feeding pipe 301;

[0050] The feeding hopper 4 is arranged above the feeding port 302, and the feeding hopper 4 can move up and down. The covering sleeve 5 is movably sleeved outside the molten metal feeding pipe 301, and the covering sleeve 5 is used to cover or open the feeding port 302 through its movable sleeving;

[0051] An active clamping mechanism 7 is arranged on the covering sleeve 5, and the active clamping mechanism 7 is clamped with the driving member 6. A driving connecting rod 8 is arranged on the circumferential side wall of the covering sleeve 5, and the covering sleeve 5 and the feeding hopper 4 are respectively rotatably installed at both ends of the driving connecting rod 8.

[0052] The casting machine body 1 is a horizontal cold chamber die casting machine. The feeding mechanism 2 is communicated with the generator end cover mold on the horizontal cold chamber die casting machine. After the mold is tightly pressed and fitted, the feeding mechanism 2 transports the molten metal into the mold for cooling, so as to complete the casting.

[0053] Specifically, according to the molten metal capacity required for casting the generator end cover, a quantitative amount of molten metal solution is taken by a measuring spoon, and then the molten metal solution is poured into the feeding hopper 4. At this time, the feeding hopper 4 is inserted into the feeding port 302 of the molten metal feeding pipe 301, so that the molten metal solution enters the inside of the molten metal feeding pipe 301 through the feeding hopper 4. Then the driving member 6 is started. The driving member 6 pushes the molten metal in the molten metal feeding pipe 301 towards the mold direction, and drives the covering sleeve 5 to move on the molten metal feeding pipe 301 through the active clamping mechanism 7. When the covering sleeve 5 moves, the feeding hopper 4 is driven to move through the driving connecting rod 8, so that the feeding hopper 4 is separated from the feeding port 302. After the feeding hopper 4 is separated from the feeding port 302, the covering sleeve 5 is not blocked by the feeding hopper 4 and is pushed by the driving member 6 to cover the feeding port 302, avoiding the situation that when the driving member 6 moves in the molten metal feeding pipe 301, the extrusion driving force splashes the molten metal out of the feeding port 302, resulting in personal injury.

[0054] A vertical plate 9 is welded on the circumferential side wall of the molten metal feeding pipe 301, and a strip-shaped groove 901 is opened on the vertical plate 9. A slider 401 is slidably installed in the strip-shaped groove 901, and the slider 401 is in an I shape;

[0055] The circumferential side wall of the feed hopper 4 is provided with a connecting rod 402, and the connecting rod 402 is welded at one end close to the vertical plate 9 and the slider 401.

[0056] When the driving member 6 drives the covering sleeve 5 to move on the molten metal feeding pipe 301 through the movable clamping mechanism 7, the driving connecting rod 8 drives the feed hopper 4 to move. The feed hopper 4 is restricted by the connecting rod 402 welded to the slider 401 and the strip-shaped groove 901 on the vertical plate 9, so that the feed hopper 4 can only move up and down on the feeding port 302. When the molten metal is pushed and extruded by the driving member 6 into the mold for forming, the feed hopper 4 moves upward to disengage from the feeding port 302, so that the covering sleeve 5 can move to block the feeding port 302. When the driving member 6 resets for casting the next generator end cover, the reset of the driving member 6 drives the covering sleeve 5 to move and reset through the movable clamping mechanism 7, so that the feeding port 302 is opened, and the feed hopper 4 is driven to move downward by the driving connecting rod 8, so that the lower end of the feed hopper 4 can be inserted into the feeding port 302, so that when the subsequent molten metal is added to the feed hopper 4, the molten metal can enter the molten metal feeding pipe 301.

[0057] A solution cavity 303 and a guiding cavity 304 are formed inside the molten metal feeding pipe 301;

[0058] The driving member 6 includes an electric cylinder 601 fixedly installed on the casting machine body 1, a telescopic rod 602 arranged on the electric cylinder 601, and a piston 603 arranged at one end of the telescopic rod 602 away from the electric cylinder 601;

[0059] The piston 603 is movably matched with the solution cavity 303, and the telescopic rod 602 is movably matched with the guiding cavity 304.

[0060] The movable clamping mechanism 7 and the telescopic rod 602 are matched and clamped. When the electric cylinder 601 drives the telescopic rod 602 to retract, the movable clamping mechanism 7 drives the covering sleeve 5 to move and open the feeding port 302, and at the same time drives the piston 603 to move to the end of the solution cavity 303 close to the guide cavity 304, wherein the inner diameter of the solution cavity 303 is larger than the inner diameter of the guide cavity 304. Therefore, when the piston 603 moves to fit the guide cavity 304, the piston 603 stops and cannot move further, and the intersection position of the guide cavity 304 and the solution cavity 303 is located on the side of the feeding port 302 away from the mold. , and the feed port 302 is opened at the position of the solution cavity 303, so when the piston 603 moves to the junction of the guide cavity 304 and the solution cavity 303, a liquid storage area is formed, and when the piston 603 moves to the junction of the guide cavity 304 and the solution cavity 303, the feed hopper 4 just moves down and inserts into the feed port 302, so that the metal liquid enters the liquid storage area in the solution cavity 303 through the feed hopper 4, so that the subsequent electric cylinder 601 drives the telescopic rod 602 to extend, pushing the piston 603 to move, so that the metal liquid in the liquid storage area enters the mold for cooling and molding.

[0061] A limiting frame 501 is provided on the outer circumferential wall of the covering sleeve 5;

[0062] The movable clamping mechanism 7 includes an L-shaped driving rod 701 movably arranged on the limiting frame 501, a retaining ring 702 arranged on the L-shaped driving rod 701, and a reset assembly 10 and a separation wedge block 703 arranged on the L-shaped driving rod 701;

[0063] The separation wedge block 703 is disposed at the bending portion of the L-shaped driving rod 701 , and the separation wedge block 703 and one end of the molten metal feeding pipe 301 are driven by abutment.

[0064] A positioning groove 604 and a sliding groove 605 are provided on the circumferential side wall of the telescopic rod 602, and the positioning groove 604 and the sliding groove 605 are connected and arranged in an L shape;

[0065] The positioning groove 604 is matched and plugged with one end of the L-shaped driving rod 701 , and the sliding groove 605 is slidably matched with one end of the L-shaped driving rod 701 .

[0066] There are two retaining rings 702 provided on the L-shaped drive rod 701, and the retaining rings 702 are respectively arranged on both sides of the limit frame 501. When the telescopic rod 602 moves to drive the L-shaped drive rod 701 to move, the retaining rings 702 can drive the covering sleeve 5 to move. Under the action of the reset assembly 10, the L-shaped drive rod 701 fits against the outer wall of the covering sleeve 5, and one end of the L-shaped drive rod 701 is inserted into the positioning groove 604. The depth of the positioning groove 604 is greater than the depth of the sliding groove 605. Therefore, when the telescopic rod 602 moves at this time, it can drive the covering sleeve 5 to move through the L-shaped drive rod 701. When the L-shaped drive rod 701 moves with the telescopic rod 602 and the separation wedge block 703 at its bent part abuts against one end of the molten metal feeding pipe 301, through the drive of the wedge surface, the L-shaped drive rod 701 moves in a direction away from the covering sleeve 5, so that one end of the L-shaped drive rod 701 inserted in the positioning groove 604 disengages and enters the sliding groove 605 as the telescopic rod 602 continues to move. At this time, the continuous movement of the telescopic rod 602 will push the piston 603 to push the molten metal into the mold for cooling and forming. Since the covering sleeve 5 cannot move with the L-shaped drive rod 701 disengaging from the positioning groove 604 of the telescopic rod 602, the molten metal is blocked at the feeding port 302 to prevent the molten metal from splashing due to the push of the piston 603.

[0067] The reset assembly 10 includes a clamping block 1001 provided on the L-shaped drive rod 701 and an annular elastic sheet 1002 that penetrates the clamping block 1001 and is sleeved outside the covering sleeve 5.

[0068] Through the setting of the clamping block 1001, the annular elastic sheet 1002 is prevented from moving left and right and finally disengaging from the tension on the L-shaped drive rod 701.

[0069] Specifically, there are two groups of L-shaped drive rods 701, which are respectively located at the upper and lower ends of the circumferential side wall of the covering sleeve 5. The clamping block 1001 is in a C shape and is welded to the L-shaped drive rod 701. The annular elastic sheet 1002 is sleeved outside the two groups of L-shaped drive rods 701, and the position of the clamping block 1001 is on the circumferential outer wall of the covering sleeve 5. Therefore, the annular elastic sheet 1002 is also sleeved outside the covering sleeve 5, and the annular elastic sheets 1002 sleeved on the covering sleeve 5 and the two groups of L-shaped drive rods 701 are circular. When the covering sleeve 5 moves to drive the L-shaped drive rod 701 to abut against the end of the molten metal feeding pipe 301, the L-shaped drive rod 701 pushes the annular elastic sheet 1002, causing the annular elastic sheet 1002 to deform into an oval shape.

[0070] The telescopic rod 602 and the piston 603 are movably connected, and an activity cavity 606 and a through hole 607 are provided at one end of the telescopic rod 602 close to the piston 603.

[0071] One end of the piston 603 close to the telescopic rod 602 is provided with a plugging rod 608, and one end of the plugging rod 608 away from the piston 603 is provided with an anti - detachment block 609;

[0072] The anti - detachment block 609 is located inside the movable cavity 606, and the plugging rod 608 and the through - hole 607 are movably plugged.

[0073] The inner diameter of the movable cavity 606 is larger than the inner diameter of the through - hole 607, and the inner diameter of the anti - detachment block 609 is smaller than the inner diameter of the movable cavity 606 and larger than the inner diameter of the through - hole 607. Thus, when the telescopic rod 602 moves towards the piston 603, when the anti - detachment block 609 moves in the movable cavity 606, the piston 603 will not be displaced due to air - flow sealing when the telescopic rod 602 starts to move.

[0074] Specifically, the piston 603 and the telescopic rod 602 are movably connected. When the telescopic rod 602 moves initially, only the L - shaped driving rod 701 is used to push the covering sleeve 5 to move, and the feeding hopper 4 is lifted. Then, the covering sleeve 5 blocks the feeding port 302. It will not push the piston 603. Therefore, during the process of the feeding hopper 4 being lifted and the covering sleeve 5 moving to block the feeding port 302, there will be no situation of metal - liquid sputtering. When the covering sleeve 5 moves to the feeding port 302 to achieve shielding, one end of the telescopic rod 602 moves to fit the piston 603. And at this time, the separating wedge - shaped block 703 on the L - shaped driving rod 701 abuts against the end of the metal - liquid feeding pipe 301, so that one end of the L - shaped driving rod 701 disengages from the positioning groove 604. The telescopic rod 602 continues to move, thereby pushing the piston 603 to move, and thus extruding the metal liquid in the liquid storage area into the mold. During the extrusion process, since the feeding port 302 is blocked by the covering sleeve 5, the metal liquid will not sputter.

[0075] A positioning ring 305 is provided on the metal - liquid feeding pipe 301, and air holes 306 are provided in the area of the guiding cavity 304 on the metal - liquid feeding pipe 301.

[0076] A clamping groove 610 is provided on the piston 603;

[0077] A deformable clamping block 307 is provided on the inner wall of the solution cavity 303, and the deformable clamping block 307 is clamped with the clamping groove 610.

[0078] When the piston 603 is at the junction of the fitting solution chamber 303 and the guiding chamber 304, the clamping groove 610 on its surface is clamped with the deformation clamping block 307 on the inner wall of the solution chamber 303. When the telescopic rod 602 moves towards the piston 603, the piston 603 is clamped by the clamping groove 610 and the deformation clamping block 307, avoiding the situation that the piston 603 moves due to the internal air flow when the telescopic rod 602 is pushed. When the telescopic rod 602 fits the piston 603, with the continuous pushing of the telescopic rod 602, the piston 603 releases the clamping of the clamping groove 610 and the deformation clamping block 307 under the thrust of the electric cylinder 601, enabling the piston 603 to move with the telescopic rod 602, thereby pushing the internal molten metal into the mold for cooling and forming, thus completing the casting of the generator end cover.

[0079] In all the solutions mentioned above, for the connection between two components, welding, the cooperation of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated here one by one. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
