Description

Technical Field

[0001] The invention belongs to the technical field of nonferrous metal casting, in particular to a low-pressure casting machine with a multifunctional material receiving structure. Background Art

[0002] Low-pressure casting of aluminum alloy wheels is an advanced non-ferrous metal casting technology. During the casting process of aluminum alloy wheels, the casting mold needs to be installed on a low-pressure casting machine, and the molten aluminum alloy is injected into the pre-designed mold under a low-pressure environment to achieve the molding of the wheel.

[0003] The patent with announcement number CN220387861U discloses a material receiving device for a low-pressure casting machine, including a material receiving tray, one end of which is connected to a second cylinder, the second cylinder is fixedly mounted on a slider, the slider is slidably connected to two sets of guide rods, and the upper end of the slider is fixedly connected to the output end of the first cylinder. In this scheme, the material receiving tray will enter between the upper and lower dies of the mold with the help of the rotational thrust of the second cylinder. Then, when the upper die base is lifted to a predetermined position, the first cylinder is first started to drive the push rod to rise, so that the slider rises synchronously along the guide rod, so that the material receiving tray reaches a certain height, which can better receive the casting, thereby avoiding bumps and damages to the product.

[0004] In the above scheme, the second cylinder not only provides rotational thrust for the receiving tray, but also plays a supporting role for the receiving tray. Since the casting is placed on the receiving tray and not directly above the second cylinder, the bearing force and the supporting force are not in the same direction, which makes the stability of the entire receiving device poor. The load-bearing load at the output end of the second cylinder is very large. Long-term use may easily cause damage such as bending and deformation at the output end of the second cylinder, thereby increasing the failure rate of the entire device and reducing the processing efficiency of the entire casting. For this reason, the present invention provides a low-pressure casting machine with a multi-functional receiving structure. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: the low-pressure casting machine with a multifunctional material receiving structure described in the present invention comprises a low-pressure casting machine main body, an upper mold and a lower mold are arranged in the low-pressure casting machine main body, a material receiving mechanism is arranged on one side between the upper mold and the lower mold, and the material receiving mechanism comprises a base, the base is fixedly mounted on the low-pressure casting machine main body, a lead screw rotatably mounted in the base, a motor fixedly mounted at one end of the base for driving the lead screw, a slider screwed to the lead screw, a slide fixedly connected to the slide, a mounting groove provided on the slide, a material receiving plate fixedly mounted in the mounting groove, a buffer pad fixedly mounted on the material receiving plate, two sets of guide grooves symmetrically provided in the base, two sets of slide rails symmetrically provided at the lower end of the slide, and the slide rails are slidably connected to the guide grooves;

[0007] The material receiving mechanism has good structural stability. While ensuring efficient handling of castings, the material receiving mechanism operates more stably and has a low failure rate, thereby improving the efficiency of the entire casting processing.

[0008] Preferably, two groups of supporting mechanisms are symmetrically arranged on both sides of the base, the supporting mechanism includes a fixed shaft, one end of the fixed shaft is fixedly connected to the base, the lower end of the support rod is rotatably connected to the fixed shaft, the fan-shaped plate is fixedly connected to the other end of the fixed shaft, a spring is arranged above the fan-shaped plate, one end of the spring is fixedly connected to the side wall of the base, and the other end of the spring is fixedly connected to the support rod, a pin is installed on one side of the support rod, an arc groove is opened on the fan-shaped plate, the pin is located in the arc groove, and two groups of fixed columns are symmetrically arranged on both sides of the base, a shaft sleeve is rotatably installed on the fixed column, and the shaft sleeve is rollingly connected to the support rod;

[0009] The shaft sleeve will squeeze the support rod, causing the support rod to rotate toward the lower die, and the shaft sleeve will roll against the support rod, and the support rod will stretch the spring. At the same time, the support rod will drive the pin to slide along the arc groove. When the receiving plate moves to just below the upper die, the shaft sleeve will roll to the upper end of the support rod, and the pin will move to the end of the arc groove, and the pin cannot move any further. At this time, the support rod, pin, and fan-shaped plate cooperate to enable the upper end of the support rod to support the entire slide plate through the shaft sleeve, thereby making the support surface of the slide plate larger, making the slide plate more stable when carrying castings, and further improving the stability of the receiving mechanism.

[0010] Preferably, a limiting mechanism is provided in the base, which includes a movable tooth plate, the movable tooth plate movably plugged into the base, two groups of U-shaped elastic bars are provided on one side of the movable tooth plate, which mesh with the tooth ring of the movable tooth plate, and are fixedly connected to the disc on the upper end face of the tooth ring, and six groups of clamps are provided above the disc at equal angles, the tooth ring and the disc are rotatably mounted at the lower end of the receiving plate, and six groups of avoidance grooves are provided at equal angles on the receiving plate and the buffer pad, the clamps are slidably connected to the avoidance grooves, and six groups of oblique grooves are provided on the disc at equal angles, and a convex shaft is provided at the lower end of the clamp, the convex shaft is located in the oblique groove, and a support frame is provided on one side of the base, and a cylinder for driving the receiving plate is fixedly mounted on the support frame, and a roller is rotatably mounted on the receiving plate, and the roller is rollingly connected to the side of the movable tooth plate;

[0011] The movable tooth plate drives the gear ring to rotate together with the disc. As the disc rotates, the six groups of cams slide along the six groups of oblique grooves respectively. Under the guidance of the oblique grooves, the cams drive the clamps to slide along the avoidance grooves toward the casting, so that the six groups of clamps close toward the casting until the casting is clamped by the six groups of clamps, thereby fixing the casting. When the casting moves back with the receiving plate, the roller will roll along the side of the movable tooth plate, so that the casting is in a fixed state during the movement. While ensuring the rapid transportation of the casting, the casting is prevented from being displaced, thereby improving the manufacturing efficiency of the entire casting.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The structural stability of the material receiving mechanism is good. While ensuring the efficient handling of castings, the material receiving mechanism operates more stably and has a low failure rate, thereby improving the efficiency of the entire casting processing.

[0014] 2. When the slider drives the slide plate and the receiving plate to move toward the bottom of the upper die, the fixed column and the shaft sleeve move with the slide plate, and the shaft sleeve will squeeze the support rod, causing the support rod to rotate toward the lower die, and the shaft sleeve rolls against the support rod, and the support rod stretches the spring. At the same time, the support rod drives the pin to slide along the arc groove. When the receiving plate moves to the bottom of the upper die, the shaft sleeve rolls to the upper end of the support rod, and the pin moves to the end of the arc groove, and the pin cannot move further. At this time, the support rod, the pin, and the fan-shaped plate cooperate so that the upper end of the support rod supports the entire slide plate through the shaft sleeve, thereby making the support surface of the slide plate larger, making the slide plate more stable when carrying castings, and further improving the stability of the receiving mechanism. Secondly, the receiving mechanism not only has the function of transporting castings, but also has a fixing effect on castings, making the receiving mechanism functionally diversified.

[0015] 3. When the casting falls onto the buffer pad, the cylinder pushes the receiving plate, and the receiving plate pushes the roller to squeeze the movable tooth plate, so that the movable tooth plate moves toward the inside of the base, and the movable tooth plate compresses the two sets of U-shaped elastic strips. At the same time, the movable tooth plate drives the gear ring to rotate together with the disc. As the disc rotates, the six groups of cams slide along the six groups of oblique grooves respectively. Under the guidance of the oblique grooves, the cams drive the clamps to slide along the avoidance grooves toward the casting, so that the six groups of clamps are closed toward the casting until the casting is clamped by the six groups of clamps, thereby fixing the casting. When the casting moves back with the receiving plate, the roller will roll along the side of the movable tooth plate, so that the casting is in a fixed state during the movement. While ensuring the rapid transportation of the casting, the casting is avoided from being displaced, thereby improving the manufacturing efficiency of the entire casting.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] Example 1: Figure 1 and Figure 2 As shown, a low-pressure casting machine with a multifunctional material receiving structure described in an embodiment of the present invention includes a low-pressure casting machine main body 1, an upper mold 2 and a lower mold 3 are provided in the low-pressure casting machine main body 1, and a material receiving mechanism 4 is provided on one side between the upper mold 2 and the lower mold 3, and the material receiving mechanism 4 includes a base 401, the base 401 is fixedly installed on the low-pressure casting machine main body 1, a screw 402 rotatably installed in the base 401, a motor 403 fixedly installed at one end of the base 401 for driving the screw 402, a slider 404 screwed to the screw 402, a slider 405 fixedly connected to the slider 404, a mounting groove 406 opened on the slider 405, a material receiving plate 407 fixedly installed in the mounting groove 406, and a buffer pad 408 fixedly installed on the material receiving plate 407, two groups of guide grooves 4011 are symmetrically opened in the base 401, and two groups of slide rails 4051 are symmetrically provided at the lower end of the slide 405, and the slide rails 4051 are slidably connected to the guide grooves 4011.

[0028] Specifically, the diameter of the buffer pad 408 is much larger than the outer diameter of the casting. In the initial state, the receiving plate 407 is located on the outside between the upper mold 2 and the lower mold 3. When the upper mold 2 and the lower mold 3 are separated, the upper mold 2 is raised to a certain height, and then the motor 403 drives the lead screw 402 to rotate, so that the slider 404 drives the slide plate 405 together with the receiving plate 407 to move toward the bottom of the upper mold 2 until the receiving plate 407 moves to the bottom of the upper mold 2 and the lower end of the casting on the upper mold 2 is close to the buffer pad 408 on the receiving plate 407. During this process, the slide rail 4051 at the lower end of the slide plate 405 slides along the guide groove 4011 The upper mold 2 is moved, and then the upper mold 2 is operated to make the casting on the upper mold 2 fall onto the buffer pad 408 of the receiving plate 407, and the upper mold 2 continues to rise until the casting is completely separated from the upper mold 2, and then the motor 403 drives the screw 402 to rotate again, so that the casting moves back with the receiving plate 407 and moves to the outside between the upper mold 2 and the lower mold 3. Finally, the casting is moved to the next process by the manipulator. Compared with the existing technology, the receiving mechanism 4 has better structural stability. While ensuring the efficient handling of castings, the receiving mechanism 4 operates more stably and has a low failure rate, thereby improving the efficiency of the entire casting processing.

[0029] like Figure 3 and Figure 4 As shown, two groups of support mechanisms 409 are symmetrically arranged on both sides of the base 401, and the support mechanism 409 includes a fixed shaft 4091, one end of the fixed shaft 4091 is fixedly connected to the base 401, the lower end of the support rod 4092 is rotatably connected to the fixed shaft 4091, and the fan-shaped plate 4093 is fixedly connected to the other end of the fixed shaft 4091. A spring 4094 is arranged above the fan-shaped plate 4093, one end of the spring 4094 is fixedly connected to the side wall of the base 401, and the other end of the spring 4094 is fixedly connected to the support rod 4092, a pin shaft 921 is installed on one side of the support rod 4092, an arc groove 931 is opened on the fan-shaped plate 4093, and the pin shaft 921 is located in the arc groove 931, and two groups of fixed columns 4012 are also symmetrically arranged on both sides of the base 401, and a shaft sleeve 4013 is rotatably installed on the fixed column 4012, and the shaft sleeve 4013 is rollingly connected to the support rod 4092.

[0030] Specifically, in the initial state, the support rod 4092 is perpendicular to the slide plate 405. The slider 404 drives the slide plate 405 together with the receiving plate 407 to move toward the bottom of the upper mold 2. The fixed column 4012 and the shaft sleeve 4013 move together with the slide plate 405. The shaft sleeve 4013 will squeeze the support rod 4092, causing the support rod 4092 to rotate toward the lower mold 3. The shaft sleeve 4013 rolls against the support rod 4092, and the support rod 4092 stretches the spring 4094. At the same time, the support rod 4092 drives the pin 921 along the arc groove 93. 1 slides, when the receiving plate 407 moves to the bottom of the upper die 2, the shaft sleeve 4013 rolls to the upper end of the support rod 4092, and the pin 921 moves to the end of the arc groove 931, and the pin 921 cannot move further. At this time, the support rod 4092, the pin 921, and the fan-shaped plate 4093 cooperate to make the upper end of the support rod 4092 support the entire slide plate 405 through the shaft sleeve 4013, so that the support surface of the slide plate 405 is larger, making the slide plate 405 more stable when carrying the casting, and further improving the stability of the receiving mechanism 4.

[0031] Example 2: Figures 5 to 8 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a limiting mechanism 410 is provided in the base 401, and the limiting mechanism 410 includes a movable tooth plate 101, the movable tooth plate 101 is movably plugged into the base 401, and two groups of U-shaped elastic bars 102 are provided on one side of the movable tooth plate 101, a tooth ring 103 engaging the movable tooth plate 101, a disc 104 fixedly connected to the upper end face of the tooth ring 103, and six groups of clamps 105 are provided above the disc 104 at equal angles, and the tooth ring 103 and the disc 104 are rotatably mounted at the lower end of the receiving plate 407, Six groups of avoidance grooves 78 are opened at equal angles on the material plate 407 and the buffer pad 408, the clamp 105 is slidably connected to the avoidance grooves 78, six groups of oblique grooves 1041 are opened at equal angles on the disc 104, a convex shaft 1051 is provided at the lower end of the clamp 105, the convex shaft 1051 is located in the oblique groove 1041, a support frame 411 is provided on one side of the base 401, a cylinder 412 for driving the receiving plate 413 is fixedly installed on the support frame 411, a roller 414 is rotatably installed on the receiving plate 413, and the roller 414 is rollingly connected to the side of the movable tooth plate 101.

[0032] Specifically, the inner diameter of the area enclosed by the six sets of clamps 105 is larger than the outer diameter of the casting. When the casting moves back along with the receiving plate 407, if the moving speed is too fast, the casting is not fixed and, under the action of inertia, it is easy for the casting to deviate, resulting in the subsequent robot arm being unable to accurately clamp the casting. If the moving speed is reduced to ensure the stability of the casting, the manufacturing efficiency of the entire casting will be reduced.

[0033] Therefore, when the casting falls onto the buffer pad 408, the cylinder 412 pushes the receiving plate 413, and the receiving plate 413 pushes the roller 414 to squeeze the movable tooth plate 101, so that the movable tooth plate 101 moves toward the inside of the base 401, and the movable tooth plate 101 compresses the two sets of U-shaped elastic bars 102. At the same time, the movable tooth plate 101 drives the gear ring 103 to rotate together with the disc 104. As the disc 104 rotates, the six groups of cams 1051 slide along the six groups of oblique grooves 1041 respectively. Under the guidance of the oblique grooves 1041, the cams 1051 drive the clamps 105 along the avoidance Let the groove 78 slide toward the casting, so that the six groups of clamps 105 are closed toward the casting until the casting is clamped by the six groups of clamps 105, thereby fixing the casting. When the casting moves back with the receiving plate 407, the roller 414 will roll along the side of the movable tooth plate 101, so that the casting is in a fixed state during the movement. While ensuring the rapid transportation of the casting, the casting is prevented from being displaced, thereby improving the manufacturing efficiency of the entire casting. Secondly, the receiving mechanism 4 not only has the function of transporting the casting, but also has a fixing effect on the casting, making the receiving mechanism 4 multifunctional.

[0034] Working principle: when the upper mold 2 is separated from the lower mold 3, the upper mold 2 rises to a certain height, and then the motor 403 drives the lead screw 402 to rotate, so that the slider 404 drives the slide plate 405 together with the receiving plate 407 to move toward the bottom of the upper mold 2, until the receiving plate 407 moves to the bottom of the upper mold 2 and the lower end of the casting on the upper mold 2 is close to the buffer pad 408 on the receiving plate 407. During this process, the slide rail 4051 at the lower end of the slide plate 405 slides along the guide groove 4011, and then the upper mold 2 is operated to make the casting on the upper mold 2 fall onto the buffer pad 408 of the receiving plate 407, and the upper mold 2 continues to rise until the casting is completely separated from the upper mold 2, and then the motor 403 drives the lead screw 402 to rotate again, so that the casting moves back with the receiving plate 407 and moves to the outside between the upper mold 2 and the lower mold 3, and finally the casting is moved to the next process by the manipulator;

[0035] When the slider 404 drives the slide plate 405 and the receiving plate 407 to move toward the bottom of the upper mold 2, the fixed column 4012 and the shaft sleeve 4013 move with the slide plate 405, and the shaft sleeve 4013 will squeeze the support rod 4092, so that the support rod 4092 rotates toward the lower mold 3, and the shaft sleeve 4013 rolls against the support rod 4092, and the support rod 4092 stretches the spring 4094. At the same time, the support rod 4092 drives the pin 921 to slide along the arc groove 931. When the receiving plate 407 moves to the bottom of the upper mold 2, the shaft sleeve 4013 rolls to the upper end of the support rod 4092, and the pin 921 moves to the end of the arc groove 931, and the pin 921 cannot move further. At this time, the cooperation of the support rod 4092, the pin 921 and the fan plate 4093 enables the upper end of the support rod 4092 to support the entire slide plate 405 through the shaft sleeve 4013;

[0036] When the casting falls onto the cushion 408, the cylinder 412 pushes the receiving plate 413, and the receiving plate 413 pushes the roller 414 to squeeze the movable tooth plate 101, so that the movable tooth plate 101 moves toward the inside of the base 401, and the movable tooth plate 101 compresses the two sets of U-shaped elastic bars 102. At the same time, the movable tooth plate 101 drives the gear ring 103 to rotate together with the disc 104. As the disc 104 rotates, the six sets of cams 1051 respectively move along the six sets of The oblique groove 1041 slides, and under the guidance of the oblique groove 1041, the convex shaft 1051 drives the clamp 105 to slide along the avoidance groove 78 toward the casting, so that the six groups of clamps 105 are closed toward the casting until the casting is clamped by the six groups of clamps 105, thereby fixing the casting. When the casting moves back with the receiving plate 407, the roller 414 will roll along the side of the movable tooth plate 101, so that the casting is in a fixed state during the movement.
