Description

Technical Field

[0001] The utility model relates to the technical field of rollover pouring for automobile castings, in particular to a rollover pouring device for automobile casting processing. Background Art

[0002] A tumble pouring system used in automotive castings is a device used to pour molten metal, such as aluminum or iron, into a mold. It typically consists of a rotating crucible or ladle to hold the molten metal. A mechanical or hydraulic system controls the angle and speed of the crucible or ladle's rotation, ensuring a smooth flow of the molten metal into the mold.

[0003] After searching, the Chinese patent "A pouring device for improving the quality of castings" authorization announcement number "CN217370445U" uses a slag baffle to block the slag floating on the molten metal to a certain extent, and uses a conical casting filter to filter impurities in the molten metal, fundamentally eliminating air holes, slag holes, and sand holes in the castings, greatly improving the finished product rate of castings and improving the intrinsic and appearance quality of castings.

[0004] In the above application, when the conical casting filter filters impurities in the metal melt, the impurities are easily accumulated on the conical casting filter. If the impurities accumulated on the conical casting filter are not removed in time, the flow rate of the melt is easily affected, thereby causing uneven casting.

[0005] Therefore, a turn-over pouring device for automobile casting processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a flip pouring device for automobile casting processing in order to solve the above-mentioned problems, thereby improving the problem that impurities are easily accumulated on the conical casting filter, and if the impurities accumulated on the conical casting filter are not removed in time, the flow rate of the melt is easily affected.

[0007] The cam is connected to the top of the driving mechanism, and the cam is connected with the transmission mechanism, and the cam is connected with the transmission mechanism, and the cam is connected with the transmission mechanism, and the cam is connected with the transmission mechanism. Through the second servo motor and the drive column, the movable frame and the push rod are lifted and lowered back and forth, and the push rod is reciprocally inserted into the filter holes of the filter screen to prevent impurities from clogging the filter holes. Compared with the existing conical casting filter, impurities are easily accumulated. If they are not removed in time, the flow rate of the melt is easily affected. This method cleans the impurities in the filter holes of the filter screen in time, avoids the risk of filter clogging, and ensures that the crucible is evenly poured into the automobile mold, thereby ensuring the effect of automobile casting processing.

[0008] Preferably, the bottom of the filter is fixedly connected to equally spaced retaining rings, and the surfaces of the retaining rings are fixedly connected to annularly spaced inclined rods, the tops of which are fixedly connected to the bottom of the filter. The inclined rods and retaining rings block large scum in the melt, preventing it from adhering to the filter pores and reducing the risk of filter clogging.

[0009] Preferably, the lower end of the surface of the push rod is fixedly connected with an annularly distributed through rod. Through the through rod, the filter holes of the filter screen are cleared, thereby improving the effect of cleaning the filter screen.

[0010] Preferably, a heat insulating sleeve is fixedly connected to the top of the slag retaining frame, and the top end of the second servo motor is fixedly connected to the inner top wall of the heat insulating sleeve. The heat insulating sleeve reduces the direct impact of high temperature on the first servo motor, thereby ensuring the service life of the first servo motor.

[0011] Preferably, a spring is fixedly connected to the inner top wall of the heat-insulating sleeve, and the bottom end of the spring is fixedly connected to the top end of the movable frame. Through the spring, the elastic force of the spring pushes the movable frame downward, ensuring that the movable frame drives the push rod and the through rod to move downward into the filter holes of the filter screen for unblocking.

[0012] Preferably, a retaining sleeve is fixedly connected to the inner top wall of the slag retaining frame, and the upper surface end of the movable frame is slidably connected to the inner wall of the retaining sleeve, thereby preventing the melt from flowing into the insulation sleeve.

[0013] Preferably, the bottom end of the driving column is rollingly connected to an annularly distributed ball bearing, and the surface of the ball bearing is rollingly connected to the inner bottom wall of the thermal insulation sleeve. The ball bearings provide support for the driving column and ensure stability of the driving column during rotation within the thermal insulation sleeve.

[0014] Preferably, the lower end of the surface of the driving column forms an angle with the horizontal plane.

[0015] The beneficial effects of the utility model are:

[0016] 1. The reciprocating lifting and lowering of the movable frame and the push rod are achieved through the second servo motor and the drive column, which in turn enables the push rod to be reciprocatedly inserted into the filter holes of the filter screen to prevent impurities from clogging the filter holes. Compared with the existing conical casting filter, which is prone to impurities gathering and affecting the flow rate of the melt if not removed in time, this method promptly cleans the impurities in the filter holes of the filter screen, avoiding the risk of filter blockage, thereby ensuring that the crucible evenly pours the melt into the automobile mold, ensuring the processing effect of automobile castings;

[0017] 2. The inclined rod and the retaining ring can block the large scum in the melt, prevent the large scum from adhering to the filter holes of the filter, and reduce the risk of filter blockage. The through rod can dredge the filter holes of the filter, improving the effect of cleaning the filter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] When implementing: Figure 1-5 As shown, a flip pouring device for automobile casting processing includes: a mobile car 1, a crucible 2 is hinged on the upper end of the surface of the mobile car 1, a reduction gearbox 3 is fixedly connected to one side of the mobile car 1, the output shaft of the reduction gearbox 3 is fixedly connected to one end of the crucible 2, the top of the mobile car 1 is fixedly connected to a first servo motor 4, the output shaft of the first servo motor 4 is fixedly connected to the input shaft of the reduction gearbox 3, and a slag blocking frame 5 is fixedly connected to the upper end of the inner wall of the crucible 2; an anti-blocking mechanism 6, the anti-blocking mechanism 6 is arranged inside the slag blocking frame 5; wherein the anti-blocking mechanism 6 includes a filter screen 61 fixedly connected to the lower end of the inner wall of the slag blocking frame 5, and the inner wall of the slag blocking frame 5 A movable frame 62 is slidably connected, and the bottom end of the movable frame 62 is fixedly connected to push rods 63 distributed in equal rows. A driving column 68 is provided on the top of the slag stopping frame 5, and the bottom end of the movable frame 62 contacts the top end of the driving column 68. The top end of the driving column 68 is fixedly connected to a second servo motor 69. The top of the slag stopping frame 5 is fixedly connected to an insulating sleeve 611, and the top end of the second servo motor 69 is fixedly connected to the inner top wall of the insulating sleeve 611. The inner top wall of the insulating sleeve 611 is fixedly connected to a spring 610, and the bottom end of the spring 610 is fixedly connected to the top of the movable frame 62. The lower end of the surface of the driving column 68 forms an angle with the horizontal plane.

[0026] The first servo motor 4 and the second servo motor 69 are both high-temperature servo motors, the thermal insulation sleeve 611 is a ceramic fiber component, the spring 610 is a nickel-based alloy component, and a guide rail is provided at the bottom of the mobile vehicle 1. The guide rail can be set in front of the automobile mold to facilitate the crucible 2 to pour molten metal into the automobile mold.

[0027] When the automobile casting needs to be processed, the mobile car 1 is driven to move to the appropriate position on the guide rail, and the first servo motor 4 is manually turned on. The first servo motor 4 drives the crucible 2 to flip to the appropriate angle through the reduction gear box 3. At this time, the slag blocking frame 5 blocks most of the slag in the melt from flowing to the liquid outlet of the crucible 2. The filter screen 61 filters the melt flowing into the liquid outlet of the crucible 2. At this time, the filtered melt is poured into the liquid inlet of the automobile mold through the liquid outlet of the crucible 2. After pouring, the crucible 2 is restored to its initial position and the first servo motor 4 is manually turned off.

[0028] During pouring, the second servo motor 69 is manually turned on, and the output shaft of the second servo motor 69 rotates to drive the driving column 68 to rotate. Because the top of the driving column 68 is tilted, the highest point of the driving column 68 pushes the movable frame 62 to move upward and squeezes the spring 610 during the rotation. After the highest point of the driving column 68 is away from the movable frame 62, the elastic force of the spring 610 pushes the movable frame 62 to move downward. The downward moving movable frame 62 drives the push rod 63 to move downward into the filter holes of the filter screen 61, so that the scum in the filter holes falls off. The rotating driving column 68 cooperates with the spring 610 to make the push rod 63 move back and forth into the filter holes of the filter screen 61, cleaning the filter screen 61, so that the melt flows smoothly into the liquid outlet of the crucible 2, and the automobile mold is evenly poured. After pouring is completed, the second servo motor 69 is manually turned off.

[0029] like Figure 3 As shown, the bottom of the filter 61 is fixedly connected with a retaining ring 66 distributed in an equal row, the surface of the retaining ring 66 is fixedly connected with an annularly distributed inclined rod 65, the top of the inclined rod 65 is fixedly connected to the bottom of the filter 61, and the lower end of the surface of the push rod 63 is fixedly connected with an annularly distributed through rod 64.

[0030] The retaining ring 66 and the plurality of inclined rods 65 prevent the large scum from flowing into the filter holes of the filter screen 61 , thereby preventing the large scum from adhering to the filter holes of the filter screen 61 and causing blockage.

[0031] like Figure 3 As shown, the inner top wall of the slag retaining frame 5 is fixedly connected to a retaining sleeve 612, and the upper surface of the movable frame 62 is slidably connected to the inner wall of the retaining sleeve 612. The upper surface of the movable frame 62 is tightly attached to the inner wall of the retaining sleeve 612. The inclined rod 65, retaining ring 66, push rod 63, through rod 64, movable frame 62, retaining sleeve 612 and filter screen 61 are all made of 302 stainless steel.

[0032] like Figure 4 As shown, the bottom end of the driving column 68 is rollingly connected to the annularly distributed balls 67 , and the surface of the balls 67 is rollingly connected to the inner bottom wall of the thermal insulation sleeve 611 .

[0033] When the utility model is in use, the second servo motor 69 is manually turned on, and the output shaft of the second servo motor 69 rotates to drive the driving column 68 to rotate. Because the top of the driving column 68 is inclined, the driving column 68 is rotating, and the highest point of the driving column 68 pushes the movable frame 62 to move up and squeezes the spring 610. After the highest point of the driving column 68 is away from the movable frame 62, the elastic force of the spring 610 pushes the movable frame 62 to move down. The movable frame 62 that moves down drives the push rod 63 to move down into the filter hole of the filter screen 61 and extends to In the retaining ring 66, the push rod 63 moves downward, driving the through rod 64 to move downward, causing the through rod 64 to move downward in the filter hole and collide with the inner side of the inclined rod 65, loosening the large scum on the inclined rod 65 and the retaining ring 66, and loosening the scum in the filter hole. Under the cooperation of the rotating driving column 68 and the spring 610, the push rod 63 moves back and forth into the filter hole of the filter screen 61, cleaning the filter screen 61, allowing the melt to flow smoothly into the liquid outlet of the crucible 2, and evenly pouring the automobile mold. After pouring is completed, the second servo motor 69 is manually turned off.

[0034] It should be noted that the mobile vehicle 1, crucible 2, reduction gearbox 3, first servo motor 4, slag retaining frame 5 and second servo motor 69 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the mobile vehicle 1, the first servo motor 4 and the second servo motor 69 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
