Technical Field

[0001] The invention relates to the technical field of vacuum die-casting, and in particular to a high-strength and lightweight distribution cabinet structural part die-casting device. Background Art

[0002] With the continuous advancement of vacuum die-casting technology, some structural components of distribution cabinets have also begun to be produced using vacuum die-casting technology. This technology effectively reduces or eliminates the pores and dissolved gases inside the casting by extracting the air in the mold cavity during the die-casting process, thereby significantly improving the mechanical properties and appearance quality of the casting. However, when conveying materials, existing vacuum die-casting equipment often brings in bubbles, which directly enter the mold and have an adverse effect on product quality.

[0013] Preferably, a ball is fixedly connected to the outer side of the two groups of slip rings, and a rack is fixedly connected to the outer side of the two groups of slip rings. The rack is located at the top of one side of the two groups of slip rings, and the rack is slidably connected to the protective shell.

[0014] Preferably, a ventilation groove is provided on the outer side of the sealing plate, a rotating shaft is rotatably connected to the inside of the sealing plate, a fan-shaped plate is fixedly connected to the bottom end of the rotating shaft, a disc is fixedly connected to the outer side of the rotating shaft, and the rotating shaft is connected to the sealing plate through a torsion spring.

[0015] Preferably, a mounting hole is opened on the outer side of the disc, a second spring is fixedly connected inside the mounting hole, and a gear block is fixedly connected to one end of the second spring;

[0016] The tooth block is slidably connected to one end of the mounting hole, and one side of the tooth block is set at an oblique angle. The tooth blocks are arranged in multiple groups, and multiple groups of the tooth blocks are meshed with the rack.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the process of die-casting the distribution cabinet structure, first start the cylinder, whose action makes the movable mold move along the guide rail and fit with the fixed mold; then, start the exhaust valve to evacuate the gas between the two molds, and connect the connecting pipe to the feeding end; finally, start the motor, which drives the screw rod to rotate in the material pipe, and transports the material from the connecting pipe to the fixed mold to complete the die-casting.

[0019] Second, when the motor drives the screw rod to convey the material, the trigger plate rotates accordingly. When the arc groove of the trigger plate is aligned with the long rod, the long rod is released from the limit and slides under the elastic force of the first spring, driving the slip ring to move along the outside of the material pipe, so that the ball at the end of the slip ring hits the vibration ring, causing the material pipe to vibrate and separate the gas in the material;

[0020] As the trigger disk continues to rotate, the long rod squeezes the first spring to reset under the limit of the trigger disk, realizing the reciprocating sliding of the long rod and the continuous impact of the ball on the vibration ring, generating continuous intermittent vibration; this process ensures that there is no gas in the material, guarantees the quality of the die-casting product, and improves the die-casting effect.

[0021] 3. When the slip ring drives the ball to hit the vibration ring, it pushes the rack to slide at the same time. Due to the bevel design of one end of the tooth block and the elasticity of the second spring, the rack cannot drive the tooth block initially, preventing the disc from rotating. When the ball is reset, the rack squeezes the non-bevel end of the tooth block, drives the disc to rotate, opens the venting groove, and discharges the separated gas. After the long rod is completely reset, the rack separates from the tooth block, the shaft is reset under the action of the torsion spring, the fan-shaped plate closes the venting groove, and closes the material pipe. During the whole process, the equipment first vibrates to separate the gas, and then opens the venting groove to exhaust, ensuring that the gas is completely discharged, reducing the opening of the material pipe, maintaining the purity of the material, and improving the quality and effect of the die-casting products.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1;

[0033] See also Figures 1 to 4 The present invention provides a technical solution: a high-strength, tough and lightweight distribution cabinet structural part die-casting device, comprising a base plate 1, a partition plate 2 fixedly connected to the top of the base plate 1, and a movable mold 3 fixedly connected to the top of the base plate 1, a fixed mold 4 is slidably connected to the top of the base plate 1, a material pipe 5 is arranged at the top of the base plate 1, a motor 6 is adapted and installed on the outer side of the partition plate 2, a screw rod 7 is fixedly connected to the output end of the motor 6, and the screw rod 7 is located inside the material pipe 5, a sleeve 8 is fixedly connected to the outer side of the base plate 1, and a sealing plate 9 is fixedly connected to the top of the material pipe 5.

[0034] Furthermore, a bracket 11 is fixedly connected to the bottom end of the bottom plate 1, and a guide rail 12 is provided at the top end of the bottom plate 1;

[0035] A guide block is provided at the bottom end of the movable mold 3 , and the guide block is located inside the guide rail 12 .

[0036] Furthermore, one end of the partition is fixedly connected to a mounting plate 21 , and the other end of the partition is fixedly connected to a fixing plate 22 , and the motor 6 is adapted to be installed on the outside of the fixing plate 22 .

[0037] Furthermore, a cylinder 31 is adapted to be installed on the outer side of the mounting plate 21 , an output end of the cylinder 31 is fixedly connected to the outer side of the movable mold 3 , and an exhaust valve 41 is provided on the top of the fixed mold 4 .

[0038] A support rod 51 is fixedly connected to the outside of the material pipe 5, and the other end of the support rod 51 is fixedly connected to the top of the partition 2. A connecting pipe 52 is fixedly connected to the top of the material pipe 5. A protective shell 53 is fixedly connected to the top of the material pipe 5, and an air cavity is opened on the outside of the protective shell 53. Two sets of vibration rings 54 are fixedly connected to the outside of the material pipe 5.

[0039] When it is necessary to die-cast the structural parts of the distribution cabinet, first, the cylinder 31 is started. The operation of the cylinder 31 drives the movable mold 3 to move along the guide rail 12, and causes the movable mold 3 to fit with the fixed mold 4. Then, the exhaust valve 41 is started to exhaust the gas between the movable mold 3 and the fixed mold 4, and the connecting pipe 52 is connected to the feeding end. Finally, the motor 6 is started. The operation of the motor 6 drives the screw rod 7 at the output end of the motor 6 to rotate inside the material pipe 5, and gradually transports the material falling from the connecting pipe 52 into the material pipe 5 to the inside of the fixed mold 4, and finally completes the die-casting work.

[0040] In summary, in the process of die-casting the structure of the power distribution cabinet, the cylinder 31 is first started, and its action causes the movable mold 3 to move along the guide rail 12 and fit with the fixed mold 4. Next, the exhaust valve 41 is started to exhaust the gas between the two molds, and the connecting pipe 52 is connected to the feeding end. Finally, the motor 6 is started, and the motor 6 drives the screw rod 7 to rotate in the material pipe 5, and the material is transported from the connecting pipe 52 to the fixed mold 4 to complete the die casting.

[0041] Example 2 improves the specific process of feeding on the basis of Example 1. The specific method can be found in Figure 5 , Figure 6 The screw rod 7 is rotatably connected to the material tube 5, and a trigger disk 71 is fixedly connected to the outer side of the screw rod 7. An arc groove 72 is provided at one end of the trigger disk 71, and an inclined surface 73 is provided at one end of the arc groove 72. The end face of the trigger disk 71 is connected to the arc groove 72 through the inclined surface 73.

[0042] Furthermore, a first spring 81 is disposed inside the sleeve 8, a long rod 82 is slidably connected to one end of the sleeve 8, and two sets of sliding rings 83 are fixedly connected to the outer side of the long rod 82;

[0043] Among them, two sets of slip rings 83 are slidably connected to the outside of the material tube 5, one end of the first spring 81 is fixedly connected to the inner wall of the sleeve 8, and the other end of the first spring 81 is fixedly connected to the long rod 82. The other end of the long rod 82 is set to be spherical and contacts the end face of the trigger disk 71.

[0044] Furthermore, a ball 831 is fixedly connected to the outer side of the two sets of slip rings 83 , and a rack 832 is fixedly connected to the outer side of the two sets of slip rings 83 . The rack 832 is located at the top of one side of the two sets of slip rings 83 , and the rack 832 is slidably connected to the protective shell 53 .

[0045] When the motor 6 is started to drive the screw rod 7 to convey the material, the trigger plate 71 fixed on the outside of the screw rod 7 is driven to rotate. When the arc groove 72 on the outside of the trigger plate 71 rotates to one end of the long rod 82, the limit of the long rod 82 is cancelled, and the long rod 82 is driven to slide under the elasticity of the first spring 81 inside the sleeve 8. The sliding long rod 82 drives the slip ring 83 fixed on the outside of the long rod 82 to slide on the outside of the material pipe 5, and causes the ball 831 at one end of the slip ring 83 to hit the vibration ring 54, thereby driving the material pipe 5 to vibrate, and the gas in the material is separated from the material under the action of the vibration.

[0046] When the trigger plate 71 rotates to one end of the long rod 82, the long rod 82 presses the first spring 81 to reset under the limit of the trigger plate 71. As a result, the trigger plate 71 continuously rotates, which causes the long rod 82 to slide back and forth and causes the ball 831 to continuously hit the vibration ring 54 to generate vibration, thereby achieving continuous intermittent vibration of the material, ensuring that there is no gas in the material, ensuring the quality of the final die-casting product, and further improving the die-casting effect.

[0047] Through the design of the inclined surface 73 and the spherical end of the long rod 82, it can be ensured that the contact between the trigger plate 71 and the long rod 82 during the rotation process can achieve a smooth transition, thereby ensuring the stability of the equipment operation.

[0048] In summary, when the motor 6 drives the screw rod 7 to transport the material, the trigger plate 71 rotates accordingly. When the arc groove 72 of the trigger plate 71 is aligned with the long rod 82, the long rod 82 is released from the limit, and slides under the elastic force of the first spring 81, driving the slip ring 83 to move along the outer side of the material pipe 5, so that the ball 831 at the end of the slip ring 83 hits the vibration ring 54, causing the material pipe 5 to vibrate and separate the gas in the material.

[0049] As the trigger plate 71 continues to rotate, the long rod 82 squeezes the first spring 81 to reset under the limit of the trigger plate 71, so that the long rod 82 can slide back and forth and the ball 831 can continuously hit the vibration ring 54, generating continuous intermittent vibration. This process ensures that there is no gas in the material, guarantees the quality of the die-casting product, and improves the die-casting effect.

[0050] Embodiment 3 is further described in detail based on the above embodiment 2. Figure 7 , Figure 8 The specific method is as follows: a ventilation groove 91 is opened on the outer side of the sealing plate 9, a rotating shaft 92 is rotatably connected inside the sealing plate 9, a fan-shaped plate 93 is fixedly connected to the bottom end of the rotating shaft 92, a disc 94 is fixedly connected to the outer side of the rotating shaft 92, and the rotating shaft 92 is connected to the sealing plate 9 through a torsion spring.

[0051] Furthermore, a mounting hole 941 is formed on the outer side of the disk 94, a second spring 942 is fixedly connected to the inside of the mounting hole 941, and a tooth block 943 is fixedly connected to one end of the second spring 942;

[0052] The tooth block 943 is slidably connected to one end of the mounting hole 941 , and one side of the tooth block 943 is set at an oblique angle. The tooth blocks 943 are arranged in multiple groups, and the multiple groups of tooth blocks 943 are meshed with the rack 832 .

[0053] When the slip ring 83 drives the ball 831 to strike the vibration ring 54, it will simultaneously drive the rack 832 to slide. Since one end of the tooth block 943 is set at an angle, and the tooth block 943 is designed to slide elastically with the second spring 942, the sliding rack 832 cannot drive the tooth block 943, and thus cannot drive the disk 94 to rotate.

[0054] When the slip ring 83 drives the ball 831 to knock the vibration ring 54 for reset, the rack 832 will squeeze the tooth block 943 which is not set with an angle during the reset process, thereby driving the disc 94 to rotate. The disc 94 drives the fan-shaped plate 93 to rotate through the rotating shaft 92, so that the air permeable groove 91 is opened, so that the gas separated from the material can be completely discharged.

[0055] After the long rod 82 is completely reset, the rack 832 is separated from the tooth block 943 , and the rotating shaft 92 is driven to reset under the action of the torsion spring, so that the fan-shaped plate 93 seals the venting groove 91 , thereby closing the material tube 5 .

[0056] Therefore, during the overall operation of the equipment, the material is first vibrated to separate the gas in the material, and then the air permeable groove 91 is opened to completely discharge the gas. The method of first vibrating and separating and then opening for exhaust can ensure that the gas can be completely discharged and reduce the opening of the material pipe 5, thereby ensuring the purity of the material and the quality of the final die-cast product, thereby once again improving the die-casting effect.

[0057] In summary, when the slip ring 83 drives the ball 831 to hit the vibration ring 54, it also pushes the rack 832 to slide. Due to the bevel design of one end of the tooth block 943 and the elasticity of the second spring 942, the rack 832 cannot initially drive the tooth block 943, preventing the disc 94 from rotating. When the ball 831 is reset, the rack 832 squeezes the non-bevel end of the tooth block 943, drives the disc 94 to rotate, opens the air groove 91, and discharges the separated gas. After the long rod 82 is fully reset, the rack 832 separates from the tooth block 943, and the rotating shaft 92 is reset under the action of the torsion spring. The fan-shaped plate 93 closes the air groove 91 and the material pipe 5. During the whole process, the equipment first vibrates to separate the gas, and then opens the air groove to exhaust the gas, ensuring that the gas is completely discharged, reducing the opening of the material pipe, maintaining the purity of the material, and improving the quality and effect of the die-casting product.

[0058] Embodiment 4: This embodiment is based on the overall operation mode of the above embodiment, which can be referred to Figures 1 to 8 , the specific method is as follows:

[0059] In the die-casting process of manufacturing the structure of the power distribution cabinet, the cylinder 31 is first activated to move the movable mold 3 along the guide rail 12 and close with the fixed mold 4. Then, the exhaust valve 41 is started to remove the gas between the molds, and the connecting pipe 52 is connected to the feeding end. Finally, the motor 6 is started, and the motor 6 drives the screw rod 7 to rotate in the material pipe 5, and the material is transported from the connecting pipe 52 to the fixed mold 4 to complete the die-casting.

[0060] When the motor 6 drives the screw rod 7 to convey the material, the trigger plate 71 rotates accordingly. When the arc groove 72 of the trigger plate 71 is aligned with the long rod 82, the long rod 82 is released from the limit and slides under the action of the first spring 81, driving the slip ring 83 to move along the outer side of the material pipe 5, so that the ball 831 at the end of the slip ring 83 hits the vibration ring 54, causing the material pipe 5 to vibrate, thereby separating the gas in the material.

[0061] As the trigger disk 71 continues to rotate, the long rod 82 squeezes the first spring 81 and resets under the limiting action of the trigger disk 71, realizing the reciprocating motion of the long rod 82 and the continuous knocking of the ball 831 on the vibration ring 54, generating continuous intermittent vibration. This process ensures that there is no gas in the material, thereby ensuring the quality of the die-casting product and improving the die-casting effect.

[0062] When the slip ring 83 drives the ball 831 to hit the vibration ring 54, it will also push the rack 832 to slide. Due to the bevel design of the tooth block 943 and the elastic effect of the second spring 942, the rack 832 cannot initially drive the tooth block 943, preventing the rotation of the disc 94. However, when the ball 831 is reset, the rack 832 squeezes the non-bevel end of the tooth block 943, drives the disc 94 to rotate, opens the vent groove 91, and discharges the separated gas. After the long rod 82 is fully reset, the rack 832 separates from the tooth block 943, and the rotating shaft 92 is reset under the action of the torsion spring. The fan-shaped plate 93 closes the vent groove 91 and the material pipe 5. During the whole process, the equipment first separates the gas by vibration, and then opens the vent groove to discharge the gas, ensuring that the gas is completely discharged, reducing the opening of the material pipe, maintaining the purity of the material, ensuring the quality of the die-casting product, and further improving the die-casting effect.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
