Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting molds, in particular to a casting mold for a marine container binding piece. BACKGROUND

[0002] The binding piece is a core fixing piece of the deck and cargo hold of a ship. Currently, marine container binding pieces such as oval binding rings and basket screw bodies are mostly produced by casting forming process. Such binding pieces, as core stress pieces for fixing the ship and the container, have strict requirements on forming precision, surface quality and production efficiency. The container is locked and fixed by the binding piece after being loaded on the ship to prevent shaking and falling during navigation. Therefore, such parts usually require high strength, impact resistance and corrosion resistance, and the material is mostly cast steel or ductile cast iron. Therefore, casting process is preferred for production, and the corresponding mold is a casting mold.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1 - Figure 7This invention provides a technical solution: a casting mold for marine container lashing components, comprising a base 1, an installation groove 11 in the middle of the base 1, sleeves 2 fixedly installed on both sides of the lower middle of the base 1, two circular holes 27 in the middle of the two sleeves 2, and a circular hole 26 above the middle of the two sleeves 2, a rotating ring 28 rotatably installed in the middle of the circular hole 27, and a lifting rod 29 fixedly installed at the upper end of the rotating ring 28, the upper end of the lifting rod 29... A connecting rod 33 is rotatably engaged with the lower end of the rotating ring 28, and a wave groove 31 is provided at the lower end of the wave groove 31. A retaining slot 32 is provided on both sides of the lower part of the wave groove 31. A gear 34 is rotatably engaged with the lower end of the sleeve 2. A connecting rod 35 is fixedly installed in the middle of the upper end of the gear 34. Transmission blocks 36 are fixedly installed on both sides of the middle of the upper end of the connecting rod 35. A guide plate 21 is fixedly installed on one side of the lower end of the base 1. A toothed plate 23 is slidably engaged with the middle of the guide plate 21. A retaining slot 32 is provided in the middle of the lower end of the base 1. A fixed groove 38 is provided, and a guide plate 42 is fixedly installed in the middle of the fixed groove 38. A telescopic rod 43 is slidably engaged in the middle of the guide plate 42. A top plate 44 is fixedly installed at the telescopic end of the telescopic rod 43. A fixed frame 24 is fixedly installed at one end of the mounting groove 11. A cylinder 25 is fixedly installed in the middle of the fixed frame 24. The output end of the cylinder 25 is fixedly connected to one end of the toothed plate 23. A guide groove 22 is provided in the middle of the guide plate 21, and the toothed plate 23 is slidably engaged in the guide groove 22. In the middle of 2, the diameter of the first circular hole 26 is smaller than that of the second circular hole 27. The lifting rod 29 is slidably engaged in the middle of the first circular hole 26. A spring 30 is provided at the upper end of the rotating ring 28 and at the connection between the first circular hole 26 and the second circular hole 27. The spring 30 is sleeved on the outer side of the middle of the lifting rod 29. The transmission block 36 and the wave groove 31 slide against each other. The transmission block 36 is engaged with the bayonet 32. The toothed plate 23 meshes with two gears 34 respectively. The top plate 44 is slidably engaged in the middle of the fixed groove 38.

[0020] In this embodiment, when the bottom pressure plate 16 needs to be pushed out, the starting cylinder 25 drives the toothed plate 23 to move to one side along the guide groove 22 opened in the guide plate 21. Since it meshes with the gears 34 at the lower end of the two sleeves 2, it will synchronously drive the two gears 34 to rotate. During the rotation of the gears 34, the connecting rod 35 at the upper end will rotate accordingly, thereby driving the two transmission blocks 36 to rotate. During the rotation of the transmission blocks 36, they will push the rotating ring 28 and the upper lifting rod 29 upward along the wave groove 31 opened in the rotating ring 28, thereby pushing the bottom pressure plate 16, which is rotatably engaged with the upper end of the lifting rod 29, upward. During the process, as the lifting rod 29 rises, the spring 30 will be compressed and in a contracted state. When the two transmission blocks 36 rotate to the two latches 32, they will be stuck. At this time, the lifting rod 29 and the upper connecting rod 33 are at their highest point. The latches 32 will limit the transmission blocks 36 to maintain the current height. After demolding, the cylinder 25 retracts and drives the toothed plate 23 to reset along the guide groove 22 opened in the guide slide plate 21. This will synchronously drive the gear 34 to rotate in the opposite direction, and the structure connected to it will also reset. During the process, the spring 30 can play a buffering role. The fixing groove 38 in the middle of the lower end of the base 1 can provide movement space for the telescopic rod 43 and the top plate 44 at the end. The guide plate 42 is used to ensure that the telescopic rod 43 can only move vertically and also to prevent the guide plate 42 from falling off.

[0021] Example 2: As Figure 1 - Figure 7 As shown, a spring 45 is provided in the middle of the telescopic rod 43, a U-shaped plate 46 is fixedly installed at the lower end of the telescopic rod 43, a transmission plate 41 is hinged to the lower end of the U-shaped plate 46, one end of the transmission plate 41 is rotatably connected to the spring 30, a bracket 37 is fixedly installed on one side of the lower middle of the base 1, a motor 39 is fixedly installed in the middle of the bracket 37, an eccentric rod 40 is fixedly installed at the eccentric end of the output end of the motor 39, one end of the eccentric rod 40 is rotatably connected to the lower end of the transmission plate 41, the upper end of the connecting rod 33 is rotatably engaged with the bottom pressure plate 16, and the top plate 44 and the bottom pressure plate 16 abut against each other.

[0022] In this embodiment, before the bottom pressure plate 16 is lifted out of the middle of the mounting groove 11 opened in the base 1, the motor 39 is started to drive the eccentric rod 40 at the output end to rotate around the center of the motor 39. The end of the eccentric rod 40 and the transmission plate 41 are rotated and engaged, so the transmission plate 41 will be driven to rotate regularly. During the process, since the transmission plate 41 and the U-shaped plate 46 are hinged, and the telescopic rod 43 is fixedly installed on the upper end of the U-shaped plate 46, the regular movement of the eccentric rod 40 will be transformed into periodic up and down shaking. Then, the top plate 44 will be driven to make the same movement through the telescopic rod 43, which can transmit the periodic vibration to the bottom pressure plate 16 to achieve demolding assistance. During the process, the spring 45 in the middle of the telescopic rod 43 can play a buffering role, thereby extending the service life of the telescopic rod 43.

[0023] Example 3: As Figure 1 - Figure 4 As shown, a bottom pressure plate 16 is slidably engaged at the lower part of the middle of the mounting groove 11. Positioning grooves 17 are provided around the upper middle part of the bottom pressure plate 16. A top pressure plate 12 is slidably engaged at the upper part of the middle of the mounting groove 11. Positioning rods 13 are fixedly installed around the lower part of the top pressure plate 12. Multiple positioning rods 13 are inserted into the corresponding positioning grooves 17. A molding space is formed between the upper end of the bottom pressure plate 16 and the middle part of the lower end of the top pressure plate 12. A pouring pipe 14 is fixedly connected to one side of the upper end of the top pressure plate 12. The pouring pipe 14 is connected to the molding space. Hook rings 15 are fixedly installed on both sides of the middle part of the upper end of the top pressure plate 12.

[0024] In this embodiment, both the bottom pressure plate 16 and the top pressure plate 12 have a half-sized injection cavity in the middle. When casting is required, the positioning rod 13 of the top pressure plate 12 can be aligned with the positioning groove 17 of the bottom pressure plate 16 by connecting it to the hook 15 through external lifting equipment or by directly holding the hook 15 by hand. When the top pressure plate 12 and the bottom pressure plate 16 are fully spliced, a complete molding space will be formed in the middle. The molten metal can be directly introduced into the complete molding space through the pouring pipe 14. After it cools down, the top pressure plate 12 can be removed from the top of the bottom pressure plate 16 by connecting it to the hook 15 through external lifting equipment or by directly holding the hook 15 by hand, and then the next demolding operation can be carried out.

[0025] Working principle: like Figure 1 - Figure 6 As shown, in use, firstly, slide the bottom pressure plate 16 into the mounting groove 11 of the base 1, with its upper positioning groove 17 facing upwards, ready to be joined with the top pressure plate 12. Then, use an external lifting device to hook the hook ring 15 of the top pressure plate 12 and lift the top pressure plate 12 above the mounting groove 11, aligning the positioning rod 13 at the lower end of the top pressure plate 12 with the positioning groove 17 of the bottom pressure plate 16. Slowly lower the top pressure plate 12 until the positioning rod 13 is fully inserted into the positioning groove 17. At this point, the middle of the top pressure plate 12 and the bottom pressure plate 16 forms a complete forming space, i.e., the casting cavity of the binding part. Then, smoothly inject the molten cast steel into the forming space through the pouring pipe 14 at the upper end of the top pressure plate 12. The pouring pipe 14 connects to the forming space to ensure that the molten metal is leak-free and free of air bubbles. After the molten metal fills the cavity, allow it to cool, and the forming of the binding part blank is completed. The top pressure plate 12 is hooked again by the lifting equipment and lifted upward. The positioning rod 13 is pulled out from the positioning groove 17, and the top pressure plate 12 is separated from the bottom pressure plate 16. At this time, the binding blank is only attached to the forming cavity of the bottom pressure plate 16, waiting to be demolded.

[0026] First, start the motor 39 at the lower end of the base 1. The eccentric rod 40 at the output end of the motor 39 rotates around the center of the motor 39. Since the end of the eccentric rod 40 is rotatably engaged with the transmission plate 41, and the transmission plate 41 is hinged to the U-shaped plate 46, the rotation of the eccentric rod 40 is converted into the periodic up-and-down vibration of the U-shaped plate 46. The vibration is transmitted to the top plate 44 through the telescopic rod 43. The top plate 44 transmits the vibration to the bottom pressure plate 16, creating a gap between the binding blank and the cavity of the bottom pressure plate 16, completing the vibration unbinding and avoiding damage to the blank during subsequent lifting.

[0027] Finally, cylinder 25 is activated. The output end of cylinder 25 drives the toothed plate 23 to move to one side along the guide groove 22 of the guide plate 21. The toothed plate 23 meshes with the gears 34 at the lower end of the two sleeves 2, synchronously driving the two gears 34 to rotate. The connecting rod 35 at the upper end of the gears 34 rotates synchronously with the gears 34, thereby driving the two transmission blocks 36 on the connecting rod 35 to rotate. During the rotation, the transmission block 36 slides along the wave groove 31 of the rotating ring 28, lifting the rotating ring 28 and the upper lifting rod 29 upward. The lifting rod 29 passes through the round hole 26, driving the bottom pressure plate 16, which is rotated and locked at the upper end, to rise synchronously. During the process, the spring 30 is compressed and contracts, playing a buffering role. When the transmission block 36 rotates to the locking position 32 of the wave groove 31, the transmission block 36 is locked and limited by the locking position 32. At this time, the lifting rod 29 and the bottom pressure plate 16 are at the highest point, completely disengaged from the installation groove 11, and maintain a stable height, making it easy for manual or robotic arms to remove the binding blank. After removal, the control cylinder 25 retracts, causing the toothed plate 23 to move in the opposite direction along the guide groove 22, simultaneously driving the gear 34 to rotate in the opposite direction. The connecting rod 35 and transmission block 36 then reset, and the rotating ring 28 falls downward under the elastic force of spring 30. The lifting rod 29 drives the bottom pressure plate 16 back into the mounting groove 11. The motor 39 stops running, and the telescopic rod 43 resets under the action of spring 45, returning the top plate 44 to the fixed groove 38. The top pressure plate 12 and bottom pressure plate 16 are then hoisted and the mold is closed. The above process is repeated to achieve batch casting.
