Description

Technical Field

[0001] The present application relates to the technical field of casting equipment, and in particular to a rotating device of a gravity casting machine. Background Art

[0002] Gravity casting refers to a process in which molten metal is poured into a metal mold cavity under the action of the earth's gravity to obtain a casting; metal mold gravity casting machines are divided into tiltable gravity casting machines and fixed gravity casting machines. The tiltable gravity casting machine flips the mold 90° during the tilting process, and the molten metal flows into the mold under the action of gravity and cools into shape.

[0003] In the prior art, a mold hinged on a fixed part is driven by a cylinder to flip. After the mold is flipped, it needs to be left to stand and cool to wait for the metal liquid to form. If the cylinder is damaged during the static process, the mold will suddenly flip, which may damage the equipment or cause harm to the operator.

[0004] Therefore, it is necessary to design a rotating device for a gravity casting machine with better safety to prevent the potential safety hazards caused by sudden flipping of the mold due to damage to the cylinder or other parts. Utility Model Content

[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a rotating device for a gravity casting machine, comprising:

[0007] Base;

[0008] A slide bar, fixed on the base;

[0009] A slider, slidably disposed on the slide bar;

[0010] A rotating plate, hinged to the slider;

[0011] A hinged rod, one end of which is hinged to the rotating plate and the other end of which is hinged to the base;

[0012] A driving cylinder is fixedly mounted on the base, and a piston rod of the driving cylinder is fixedly connected to the slider;

[0013] The lower die is fixed on the rotating plate;

[0014] An upper die is movably disposed on a rotating plate;

[0015] The anti-fall structure comprises:

[0016] Two clamping plates are movably arranged on the slide block, and the two clamping plates are arranged oppositely on two sides of the slide bar;

[0017] The driving assembly is movably connected with the clamping piece to drive the clamping piece to clamp the slide bar.

[0018] During the working process, since the sliding rod, the block, the rotating plate, the hinged rod and the driving cylinder are provided, the extension and retraction of the driving cylinder can drive the sliding rod to move along the sliding rod, thereby pushing the rotating plate to flip during the flipping of the hinged rod; since the clamping plate and the driving assembly are provided, the driving assembly can drive the clamping plate to clamp the sliding rod, and when the sliding rod moves to the appropriate position, the clamping plate provided on the sliding rod clamps the sliding rod, thereby fixing the position of the sliding rod relative to the sliding rod; if the driving cylinder or other components are damaged, the sliding rod will not move relative to the sliding rod, and the rotating plate will not flip; the provision of the clamping plate improves the safety of the gravity casting machine and can avoid equipment damage or personal injury caused by accidental damage to components.

[0019] Furthermore, the driving assembly comprises:

[0020] A fixed plate, fixed on the slider;

[0021] A connecting block is fixed on the clamping piece;

[0022] A movable rod is rotatably arranged on the fixed plate, one end of the movable rod close to the clamping piece is hinged to the connecting block, and the other end away from the clamping piece is rotatably arranged with a driving rod;

[0023] The driving plate is formed with two driving grooves arranged opposite to each other, and the driving rod is movably arranged in the driving grooves;

[0024] The anti-falling cylinder is fixed on the fixing plate, and the piston rod of the anti-falling cylinder is fixedly connected with the driving plate.

[0025] Furthermore, a fitting surface that fits with the side wall of the slide rod is formed on the clamping sheet.

[0026] Furthermore, two slide bars are provided, and load-bearing plates are fixedly provided at both ends of the slide bars, and the load-bearing plates are fixedly provided on the base;

[0027] The slide blocks on the two slide bars are fixedly connected through a connecting plate. Two oppositely arranged mounting plates are fixedly arranged near two ends of the connecting plate. The rotating plate is hinged to the mounting plate.

[0028] Further, one end of the rotating plate away from the mounting plate is hinged to the hinge rod;

[0029] An articulated seat is fixedly arranged on one end of the base away from the sliding block, and one end of the articulated rod away from the rotating plate is articulated with the articulated seat.

[0030] Furthermore, two oppositely arranged mold clamping cylinders are fixedly arranged on the rotating plate, and push plates are fixedly arranged on two opposite side walls of the upper mold, and the piston rods of the mold clamping cylinders are fixedly connected to the push plates.

[0031] Furthermore, a liquid storage port is fixedly provided on the side wall of the lower mold, and the liquid storage port is communicated with the inner cavity of the lower mold.

[0032] Furthermore, a cover plate corresponding to the liquid storage port is fixedly provided on the upper mold.

[0033] The beneficial effects of this application are:

[0034] 1. When the slider moves to the target position, the driving assembly can drive the clamping piece to clamp the slider, thereby fixing the position of the slider relative to the slider. When the driving cylinder or other components are damaged, the slider will not move relative to the slider, so that the rotating plate will not accidentally flip over, thereby improving the safety performance of the gravity casting machine and the rotating device;

[0035] 2. The setting of the cover plate can prevent the molten metal from flowing out during the flipping process. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0052] A rotating device for a gravity casting machine, comprising: a base 1, a sliding rod 101, a sliding block 102, a rotating plate 103, a hinge rod 104, a driving cylinder 105, a lower die 2, and an upper die 201;

[0053] Specifically, the base 1 is a rectangular plate structure, which is set on the ground, and the two slide bars 101 are relatively set on the base 1; specifically, the two ends of the slide bar 101 are fixedly installed with a load-bearing plate 106, and the load-bearing plate 106 is fixedly installed on the base 1; the two slide bars 101 are slidably provided with sliders 102, the top surfaces of the two sliders 102 are fixedly connected by a connecting plate 107, and the two opposite side walls of the sliders 102 are fixedly connected by a piston plate 108, and the driving cylinder 105 is fixedly installed on the base 1, and the piston rod of the driving cylinder 105 is fixedly connected to the piston plate 108 so that the slider 102 can be pushed to slide along the slide bar 101 during the extension and retraction of the driving cylinder 105;

[0054] Two mounting plates 109 are fixedly arranged opposite to each other on the top surface of the connecting plate 107 near both ends, and the rotating plate 103 is arranged between the two mounting plates 109 and is hinged to the mounting plates 109; one end of the rotating plate 103 away from the mounting plate 109 is hinged to one end of the hinged rod 104, and two hinged seats 110 are fixedly arranged opposite to each other on the end of the base 1 away from the slider 102, and one end of the hinged rod 104 away from the rotating plate 103 is hinged to the hinged seat 110;

[0055] The arrangement of the slide bar 101, the slider 102, the hinged rod 104, and the rotating plate 103 forms a triangular structure. The slider 102 drives the rotating plate 103 to move during its movement. The rotating plate 103 continuously approaches the hinged rod 104. The hinged rod 104 rotates and pushes the rotating plate 103 to flip, thereby realizing the flipping of the gravity casting machine.

[0056] Four support columns 202 are fixedly installed on the bottom surface of the lower mold 2, and the bottom surfaces of the four support columns 202 are fixedly connected to the top surface of the rotating plate 103; the upper mold 201 is arranged above the lower mold 2, and two opposite side walls of the rotating plate 103 are fixedly installed with two oppositely arranged mold clamping cylinders 203, and two opposite side walls of the upper mold 201 are fixedly installed with push plates 204, and the piston rods of the two mold clamping cylinders 203 are respectively fixedly connected to the corresponding push plates 204. The mold clamping cylinders 203 can drive the upper mold 201 to move during the extension and retraction process, thereby realizing mold opening and mold closing;

[0057] A liquid filling port 205 is fixedly installed on the side wall of the lower mold 2, and the liquid filling port 205 is connected to the inner cavity of the lower mold 2 to pour the molten metal into the mold cavity; a cover plate 206 corresponding to the liquid filling port 205 is fixedly installed on the upper mold 201. When the lower mold 2 and the upper mold 201 are closed, the cover plate 206 can close the liquid filling port 205, and the molten metal flows out during the flipping of the rotating plate 103.

[0058] The rotating device of the gravity casting machine also includes an anti-falling structure 3. The anti-falling structure 3 can fix the slider 102 on the slide bar 101 to prevent the rotating plate 103 from suddenly turning over due to accidental damage to the driving cylinder 105 or other components, thereby causing damage to the gravity casting machine or the rotating device or injury to the operator.

[0059] Specifically, the anti-falling structure 3 includes two clamping pieces 301 and a driving assembly 302 movably connected to the clamping pieces 301; the clamping pieces 301 are movably arranged on the slider 102, and the two clamping pieces 301 are relatively arranged on both sides of the slide bar 101 to clamp and lock the slide bar 101; the clamping pieces 301 are formed with a fitting surface 303 that fits with the circumferential side wall of the slide bar 101, and the fitting surface 303 increases the contact area between the clamping pieces 301 and the slide bar 101, thereby increasing the friction force;

[0060] The driving assembly 302 includes: a fixed plate 304, a connecting block 305, a movable rod 306, a driving plate 307, and an anti-falling cylinder 308; specifically, the fixed plate 304 is fixedly mounted on the slider 102, the movable rod 306 is rotatably mounted on the fixed plate 304 near the middle, the connecting block 305 is fixedly mounted on the clamping plate 301, the end of the movable rod 306 close to the clamping plate 301 is hinged to the connecting block 305, and the end of the movable rod 306 away from the tightening plate is rotatably provided with a driving rod 309; two driving grooves 310 arranged opposite to each other are formed on the driving plate 307, and the driving rod 309 is movably arranged in the driving groove 310; the anti-falling cylinder 308 is fixedly mounted on the fixed plate 304, and the piston rod of the anti-falling cylinder 308 is fixedly connected to the driving plate 307;

[0061] The extension and retraction of the anti-fall cylinder 308 can push the driving plate 307 to move. During the movement of the driving plate 307, the driving groove 310 can push the movable rod 306 to rotate so that the clamping plate 301 can clamp the sliding rod 101, thereby locking the position of the slider 102 relative to the sliding rod 101, thereby improving the safety performance of the gravity casting machine and the rotating device.
