Description

Technical Field

[0001] The present invention relates to the technical field of die-casting, and specifically to a die-casting forming device for a motor end cover. Background Art

[0002] The motor end cover is an important part of the motor, usually installed at the end of the motor, playing a role in protecting the internal components of the motor, such as the stator and rotor, and preventing external substances such as dust and water vapor from entering. The existing motor end covers are mainly made by die-casting process.

[0003] Die-casting is a metal casting process, usually used to produce small and medium-sized castings with precise dimensions and clear contours. During die-casting, first, the metal is melted, and then it is quickly injected into a precisely manufactured mold under high pressure. The pressure is maintained until the metal solidifies, and then the casting is removed from the mold.

[0004] For the existing devices for die-casting motor end covers, in order to be able to batch die-cast the motor end covers, multiple die-casting stations are usually opened on a piece of die steel, and the multiple die-casting stations are interconnected through the opened runners, so that the molten metal can flow to the multiple die-casting stations, thereby batch die-casting the motor end covers.

[0005] However, when die-casting in the above manner, the molten metal inside the runner will be connected to the molten metal inside the die-casting station. After the metal cools, the metal inside the runner and the formed motor end cover become one body, so that subsequent processes for separating the batch die-cast motor end covers from each other need to be added, thereby reducing the processing efficiency of the motor end covers. Moreover, when cutting off the metal materials connecting the motor end covers, material waste will inevitably occur, thereby increasing the processing cost of the motor end covers. In addition, the existing technology usually uses a manipulator to take out the die-cast end covers, but the procurement and maintenance costs of the manipulator are relatively high and are not suitable for small-scale factories.

[0018] The beneficial effects of the present invention are: 1.

[0019] 2. The present invention uses a driving component to drive the extrusion component to recover the molten metal inside the flow channel after the cut-off block separates the flow channel from the die-casting station, thereby avoiding metal waste and reducing the processing cost of the motor end cover.

[0020] 3. The present invention adopts a sliding component to automatically drive the movable frame to extend between the movable mold and the fixed mold when the movable mold and the fixed mold are separated from each other, so that the movable frame can drive the conveyor belt to move to the lower part of the die-casting station, so that the conveyor belt can receive and transport the motor end cover after die-casting, without the need for a robot to grab the motor end cover, thereby reducing the cost of procurement and maintenance.

[0021] Fourth, the present invention adopts a direction adjustment component to automatically adjust the direction of the motor end cover when the motor end cover falls onto the conveyor belt, so that one surface of the motor end cover is always facing upward, thereby facilitating the subsequent fine processing of the motor end cover and further increasing the processing efficiency of the motor end cover.

Specific embodiments

[0039] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0040] Refer to Figure 1 , a die-casting forming device for a motor end cover, comprising a device frame 1, a fixed mold 2 is fixedly installed on the left part of the device frame 1, an ejector rod 22 is slidably arranged left and right on the fixed mold 2, a moving mold 3 is slidably arranged left and right on the right part of the device frame 1, a pressurizing push rod 4 and a feeding pipe 5 are arranged on the upper part of the device frame 1 through an electric slider 11, a recycling mechanism 6 for recycling raw materials is jointly arranged on the moving mold 3 and the fixed mold 2, and a conveying mechanism 7 for conveying end covers is arranged on the device frame 1.

[0041] When die-casting forming the motor end cover is required, first, the moving mold 3 and the fixed mold 2 are combined together through the recycling mechanism 6, then the electric slider 11 drives the feeding pipe 5 to move to the directly above the moving mold 3 and the fixed mold 2, and then the molten metal raw material is injected into the runner inside the moving mold 3 and the fixed mold 2 through the feeding pipe 5. The molten metal raw material flows through the runner to the inside of each die-casting station, and then the electric slider 11 drives the pressurizing push rod 4 to move to the directly above the moving mold 3 and the fixed mold 2. By extending the telescopic section of the pressurizing push rod 4 into the inside of the moving mold 3 and the fixed mold 2, the molten metal inside the die-casting station is pressurized.

[0042] Next, the die-casting station is separated from the runner by the recovery mechanism 6. Then, the recovery mechanism 6 recovers the molten metal inside the runner. After the metal inside the die-casting station cools down, the moving die 3 is moved to the right by the recovery mechanism 6, so that the moving die 3 is separated from the fixed die 2. Immediately afterwards, the conveying mechanism 7 automatically extends between the moving die 3 and the fixed die 2, and the ejector rod 22 is extended to the right. The ejector rod 22 pushes the die-cast motor end cover onto the conveying mechanism 7, and the motor end cover is transported out by the conveying mechanism 7.

[0043] It should be noted that an electric telescopic rod is fixedly installed on the left side of the device frame 1, and the telescopic section of the electric telescopic rod is fixedly connected to all the ejector rods 22 at the same time. By extending the telescopic section of the electric telescopic rod, the ejector rod 22 can be driven to push the motor end cover.

[0044] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in

[0045] It should be noted that the above storage device refers to a vessel in the prior art for storing molten metal raw materials, such as a melting tank.

[0046] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0047] When the truncation block 61 does not move, the truncation block 61 is completely retracted inside the fixed die 2. The fixed die 2 blocks the outlet of the through groove on the truncation block 61, so that the metal raw material cannot flow out of the through groove on the truncation block 61 into the inside of the moving die 3 and the fixed die 2. When pressurizing the metal raw material inside the moving die 3 and the fixed die 2, the pressure of the metal raw material remains unchanged, and the pushing spring pushes the opening and closing plate 623 to the right, so that the right side surface of the opening and closing plate 623 abuts against the truncation block 61, so that the opening and closing plate 623 closes the outlet of the through groove on the truncation block 61, further preventing the pressurized metal raw material from flowing out of the outlet of the through groove on the truncation block 61.

[0048] After the pressure - applying push rod 4 applies pressure to the metal raw material inside the moving die 3 and the fixed die 2, the telescopic section of the first hydraulic cylinder 622 extends to drive the adjusting plate 621 to move to the right. The adjusting plate 621 drives all the cutting blocks 61 to move to the right synchronously, so that the right end face of the cutting block 61 abuts tightly against the moving die 3, thereby separating the runner on the moving die 3 and the fixed die 2 from the die - casting station.

[0049] When the moving die 3 and the fixed die 2 are just combined together, the moving die 3 fits on the right - end face of the pushing column 624, but the moving die 3 does not push the pushing column 624 to move. Due to the blocking of the pushing column 624 by the moving die 3, the pushing column 624 and the opening - closing plate 623 cannot move to the right. Thus, when the cutting block 61 moves to the right, the opening - closing plate 623 no longer closes the through - slot outlet of the cutting block 61. Furthermore, the metal raw material inside the runner flows from the through - slot of the cutting block 61 into the interior of the storage device under the action of pressure.

[0050] Refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 Recycling mechanism 6 further includes a mounting bracket 65 fixedly installed on the right - side surface of the moving die 3. An extrusion assembly 63 for extruding the runner is arranged on the moving die 3. The extrusion assembly 63 includes a pushing member 632 slidably arranged left - and - right on the mounting bracket 65. A central push rod 633 is fixedly installed at the center position on the left side of the pushing member 632. The central push rod 633 slidably penetrates through the center position inside the moving die 3 left - and - right. Inside the moving die 3, a number of groups of side push rods 634 are arranged in one - to - one correspondence with the runners. Each group of side push rods 634 is composed of a number of side push rods 634 arranged at equal intervals along the length direction of the corresponding runner inside the moving die 3. The side push rods 634 are slidably connected to the moving die 3 left - and - right. The right ends of the side push rods 634 in the same group are flush, and the right ends of the side push rods 634 in different groups are arranged staggeredly left - and - right.

[0051] Refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 14 and Figure 15 Recycling mechanism 6 further includes a driving assembly 64 arranged on the mounting bracket 65 for driving the extrusion assembly 63. The driving assembly 64 includes active pushing members 641 arranged at equal intervals along the circumference of the central push rod 633 on the pushing member 632. The active pushing members 641 are slidably connected to the pushing member 632 along the length direction of the corresponding runner. The active pushing members 641 are in one - to - one correspondence with each group of side push rods 634. The left sides of the active pushing members 641 are arranged staggeredly left - and - right. A stepped structure is arranged on the left side of the active pushing members 641. The right ends of the side push rods 634 are provided with inclined surfaces. A power part 642 for driving the active pushing members 641 is arranged on the mounting bracket 65.

[0052] Refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 14 and Figure 15 and Figure 15 , the power unit 642 includes a synchronous rotating member 6421 rotatably arranged on the right side of the pushing member 632. Push-pull plates 6422 are hinged to the outside of the synchronous rotating member 6421 at equal intervals along its circumference. One end of the push-pull plate 6422 away from the synchronous rotating member 6421 is hinged to the corresponding active pushing member 641. A rotating sleeve 6423 is coaxially and fixedly installed on the right side of the synchronous rotating member 6421. A spiral groove is provided on the rotating sleeve 6423. A second hydraulic cylinder 6426 is fixedly installed on the right part of the mounting bracket 65. A moving circular plate 6424 is fixedly installed at the telescopic section of the second hydraulic cylinder 6426. The moving circular plate 6424 slides left and right through the inside of the rotating sleeve 6423. A protruding column slidably connected to the inside of the spiral groove is arranged on the outside of the moving circular plate 6424. A spiral spring is arranged between the moving circular plate 6424 and the pushing member 632. A third hydraulic cylinder 6425 is fixedly installed on the right side of the device frame 1. The telescopic section of the third hydraulic cylinder 6425 is fixedly connected to the mounting bracket 65.

[0053] When the right end face of the truncating block 61 abuts against the moving mold 3, the telescopic section of the extended second hydraulic cylinder 6426 drives the moving circular plate 6424 to move to the left. The moving circular plate 6424 pushes the pushing member 632 to the left through the spiral spring. The pushing member 632 drives the central push rod 633 to move to the left until its left end face abuts against the fixed mold 2, so that the central push rod 633 blocks and closes the middle part of the runner, and the metal raw material in the middle part of the runner is pushed away from the center of the runner by the insertion of the central push rod 633, so that the metal raw material flows into the inside of the truncating block 61 through the through groove.

[0054] It should be noted that a protruding block for blocking the pushing member 632 from moving to the right is provided on the mounting bracket 65. After the central push rod 633 is completely retracted into the moving mold 3, the pushing member 632 moves to abut against the protruding block, thereby preventing the metal raw material after pressurization from pushing the central push rod 633 to the right, resulting in a decrease in the pressure of the metal raw material and a deterioration of the die-casting effect.

[0055] When the central push rod 633 abuts against the fixed mold 2, the telescopic section of the second hydraulic cylinder 6426 continues to extend, causing the moving circular plate 6424 to continue moving to the left. At this time, since the pushing member 632 is blocked by the fixed mold 2 through the central push rod 633, it no longer moves to the left. As a result, the pushing member 632 drives the rotating sleeve 6423 to stop moving to the left synchronously through the synchronous rotating member 6421. The moving circular plate 6424 moving to the left pushes the spiral groove of the rotating sleeve 6423 through the protruding columns thereon, causing the rotating sleeve 6423 to drive the synchronous rotating member 6421 to rotate.

[0056] When the synchronous rotating member 6421 rotates, it pulls the active pushing member 641 towards the central push rod 633 through the push-pull plate 6422, causing the active pushing member 641 to cooperate with the inclined surfaces of the corresponding side push rods 634 in sequence from the inside out through the stepped structure thereon. As a result, each group of side push rods 634 move to the left in sequence from the inside out until they abut against the fixed mold 2, and further cause the side push rods 634 to gradually push the metal raw material inside the runner into the inside of the cutting block 61, thereby recovering the metal raw material inside the runner.

[0057] It should be noted that the side push rod 634 is provided with a protruding plate, and the right side surface of the moving mold 3 is provided with a limiting plate for blocking the protruding plate. After the side push rod 634 is completely retracted into the moving mold 3, the protruding plate on the side push rod 634 moves to abut against the limiting plate, thereby preventing the metal raw material after pressurization from pushing the side push rod 634 to the right, reducing the pressure of the metal raw material, and resulting in a poor die-casting effect.

[0058] When the metal raw material cools, the telescopic section of the third hydraulic cylinder 6425 is retracted to drive the moving mold 3 to move to the right through the mounting bracket 65, causing the moving mold 3 and the fixed mold 2 to separate from each other.

[0060] Refer to Figure 10 、 Figure 11 and Figure 12, on the moving frame 72 on the same support plate 71, a rotating assembly 75 for driving the rotating roller 73 is jointly provided.

An actuating motor 752 is fixedly installed on the right side of the connecting plate 751. The output shaft of the actuating motor 752 is connected to two rotating rollers 73 at corresponding upper and lower positions through a belt.

A driven gear 764 is fixedly installed at the lower part of the rope reel 763. The diameter of the driven gear 764 is smaller than that of the rope reel 763. A driving rack 765 meshing with the driven gear 764 is fixedly installed on the front right side of the installation bracket 65. A locking portion 766 for locking the fixed support plate 761 is provided on the front support plate 71.

[0062] Continue to refer to Figure 10 , Figure 11 and Figure 12 , the locking portion 766 includes an L-shaped locking member 7661 slidably arranged left and right on the front part of the front support plate 71. An inclined surface gradually inclined backward from left to right is provided at the left end of the transverse section of the L-shaped locking member 7661. A tension spring is arranged between the longitudinal section of the L-shaped locking member 7661 and the front support plate 71. The tension spring pulls the longitudinal section of the L-shaped locking member 7661 to abut against the right side surface of the moving mold 3.

[0063] Continue to refer to Figure 10 , Figure 11 and Figure 12 , the sliding assembly 76 further includes a synchronization portion 767 arranged at the lower part of the device frame 1 for synchronously moving two connecting plates 751 in opposite directions.

Hinge plates 7672 are symmetrically hinged to the front and rear sides on the left side of the sliding rod 7671. The ends of the hinge plates 7672 far from the sliding rod 7671 are respectively hinged to the corresponding connecting plates 751.

[0064] In the state where the moving mold 3 and the stationary mold 2 are combined together, the fixed support plate 761 is located at the front part of the horizontal section of the L-shaped locking member 7661, so as to block the backward movement of the fixed support plate 761 through the horizontal section of the L-shaped locking member 7661, enabling the fixed support plate 761 to drive the front moving frame 72 at the front side through the connecting plate 751 at the front side to be located at the front part of the moving mold 3 and the stationary mold 2. When the connecting plate 751 at the front side moves forward, it pulls the sliding rod 7671 to the left through the hinge plate 7672. When the sliding rod 7671 moves to the left, it drives the connecting plate 751 at the right side to move backward synchronously through the hinge plate 7672 at the rear side. The connecting plate 751 at the right side drives the moving frame 72 at the rear side to move, so that the moving frames 72 at the front and rear sides can move synchronously in the opposite direction.

[0065] When the moving mold 3 moves to the right, the moving mold 3 pushes the L-shaped locking member 7661 to move synchronously to the right. When the moving mold 3 moves to be completely separated from the stationary mold 2, the L-shaped locking member 7661 moves to the right side of the fixed support plate 761, so that the L-shaped locking member 7661 no longer blocks the fixed support plate 761. At this time, the return spring pulls the sliding rod 7671 to the right, so that the sliding rod 7671 drives the moving frames 72 on both sides to approach each other through the hinge plate 7672, so that the moving frame 72 drives the conveyor belt 74 thereon to move between the moving mold 3 and the stationary mold 2 and be located below the die-casting station.

[0066] When the conveyor belt 74 moves between the moving mold 3 and the stationary mold 2, the actuating motor 752 is started to drive the rotating roller 73 at the corresponding position to rotate. The rotating roller 73 drives the conveyor belt 74 at the corresponding position to rotate. After the conveyor belt 74 starts to rotate, the telescopic section of the extended electric telescopic rod drives the ejector rod 22 to move to the right, so that the ejector rod 22 ejects the die-cast machine end cover out of the stationary mold 2, so that the motor end cover falls onto the conveyor belt 74.

[0067] Refer to Figure 1 、 Figure 4 、 Figure 12 and Figure 13 As shown in, the conveying mechanism 7 further includes an orientation adjusting assembly 77 provided on the moving frame 72 for adjusting the orientation of the end cover. The orientation adjusting assembly 77 includes a guide plate 771 fixedly installed on the upper part of the moving frame 72 near one side of the middle part of the device frame 1. One side of the guide plate 771 near the middle part of the device frame 1 is structured to be gradually inclined upward from left to right, and the side of the guide plate 771 away from the middle part of the device frame 1 is a horizontal structure. A blocking belt 772 is fixedly installed on the left side of the left conveyor belt 74. A driving push plate 773 is slidably arranged left and right at a position on the upper part of the moving frame 72 near the middle part of the device frame 1. A compression spring is arranged between the driving push plate 773 and the moving frame 72. The left side of the right conveyor belt 74 is provided with inclined push plates 774 fixedly connected thereto at equal intervals along its track.

[0068] When the motor end cover falls from the inside of the fixed mold 2, the motor end cover falls vertically onto the guide plate 771. After that, the conveyor belt 74 rotating to the right pushes the active push plate 773 to the left through the inclined plane push plate 774 on it, so that the active push plate 773 pushes the lower part of the motor end cover to the left, causing the upper part of the motor end cover to tilt to the right, and then making the motor end cover tilt at a position on the guide plate 771 close to the middle of the device frame 1. And the blocking belt 772 on the conveyor belt 74 on the left prevents the motor end cover from slipping outside the conveyor belt 74. At the same time, the conveyor belt 74 drives the motor end cover to gradually move away from the middle of the device frame 1 along the guide plate 771, and then makes the motor end cover gradually rotate to a horizontal state along the guide plate 771, so as to adjust the side of the motor end cover close to the fixed mold 2 to face upward.

[0069] After moving the motor end cover out of the fixed mold 2, the telescopic section of the third hydraulic cylinder 6425 extends and moves to the left to drive the mounting bracket 65, driving the movable mold 3 and the fixed mold 2 to be combined together again, so as to continuously die-cast the motor end cover. When the mounting bracket 65 moves to the left, it drives the driven gear 764 to rotate through the active rack 765. The driven gear 764 drives the rope reel 763 to rotate at an accelerated speed. The rope reel 763 drives the fixed support plate 761 to move forward to the inclined plane of the L-shaped locking part 7661 by pulling the steel wire rope, so that the fixed support plate 761 pushes the L-shaped locking part 7661 to the right. When the fixed support plate 761 moves to the front side of the L-shaped locking part 7661, the L-shaped locking part 7661 is blocked behind the fixed support plate 761 again under the pull of the tension spring, thus fixing the position of the fixed support plate 761. At this time, the fixed support plate 761 drives the front moving frame 72 to move to the front part of the movable mold 3 and the fixed mold 2 through the front connecting plate 751, and at the same time, the rear moving frame 72 moves to the rear part of the movable mold 3 and the fixed mold 2, thereby preventing the moving frame 72 from hindering the clamping of the movable mold 3 and the fixed mold 2.

[0070] When die-casting the motor end cover in the present invention, the following steps are included: In the first step, the telescopic section of the third hydraulic cylinder 6425 extends and drives the movable mold 3 and the fixed mold 2 to be combined together by moving the mounting bracket 65 to the left. After that, the molten metal raw material is injected into the runner inside the movable mold 3 and the fixed mold 2 through the feeding pipe 5. Then, the telescopic section of the pressure push rod 4 is extended into the inside of the movable mold 3 and the fixed mold 2, so as to pressurize the molten metal inside the die-casting station.

[0071] In the second step, extend the telescopic section of the first hydraulic cylinder 622 to drive the right end face of the cutting block 61 to abut tightly against the moving mold 3, so that the cutting block 61 separates the runner on the moving mold 3 and the fixed mold 2 from the die-casting station. Extend the telescopic section of the second hydraulic cylinder 6426 to drive the left end face of the central push rod 633 to abut against the fixed mold 2. Continuously extend the telescopic section of the second hydraulic cylinder 6426, so that the active pusher 641 drives the side push rod 634 to push the metal raw material inside the runner into the cutting block 61 in sequence, thereby recycling the metal raw material inside the runner.

[0072] In the third step, contract the telescopic section of the third hydraulic cylinder 6425 to drive the moving mold 3 to move to the right through the mounting bracket 65, so that the moving mold 3 and the fixed mold 2 are separated from each other. The moving mold 3 drives the conveyor belt 74 on the moving frame 72 to move between the moving mold 3 and the fixed mold 2 and below the die-casting station by pushing the L-shaped locking member 7661.

[0073] In the fourth step, start the execution motor 752 to drive the conveyor belt 74 to rotate. Extend the telescopic section of the electric telescopic rod to drive the ejector rod 22 to move to the right, so that the motor end cover drops onto the guide plate 771. The conveyor belt 74 pushes the motor end cover to tilt at a position on the guide plate 771 close to the middle of the device frame 1 through the active push plate 773, thereby adjusting the side of the motor end cover close to the fixed mold 2 to face upward.

[0074] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
