Description

Technical Field

[0001] This invention relates to the field of casting technology, specifically to a casting apparatus with a safety protection mechanism for processing marine parts. Background Technology

[0002] Marine fittings come in a wide variety of types, with bolts generally falling into two categories: external and internal. External bolts are primarily exposed to water corrosion and require higher strength and toughness. Their production typically employs costly processes such as forging and rolling to ensure compliance with standards. Internal bolts, on the other hand, generally have less stringent requirements regarding their operating environment and strength, making them more suitable for lower-cost processes like casting. Bolt casting involves four core stages: mold forming, molten metal pouring, cooling and solidification, and demolding. The core requirements of this process are concentrated in three points: First, precise mold switching, requiring rapid and stable switching of the casting mold to a horizontal state to ensure uniform filling of the mold cavity with molten metal and avoid defects in critical structures such as threads and heads. Second, efficient pouring and rapid solidification, requiring rapid heat dissipation after pouring to shorten the production cycle while ensuring uniform bolt hardness. Third, safe and flexible demolding, requiring the demolding process to avoid impacts and deformation of the bolt surface, and ensuring safe and reliable operation to reduce the risk of human intervention.

[0003] When the bolts are demolded, they fall directly to the ground or into the metal frame without any cushioning support after being removed from the mold. The impact of the fall can cause the bolt head to chip and the threads to deform. For high-strength bolts, the fall may also cause them to break, further reducing the pass rate. Summary of the Invention

[0004] The present invention provides a casting apparatus with a safety protection mechanism for processing marine parts, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a casting device with a safety protection mechanism for processing marine parts, including a processing table for supporting the casting device for marine parts, wherein a quadrilateral plate is fixedly installed on the top of the processing table;

[0015] The end of the compensating rod away from the first telescopic rod is pressed and adapted to the quadrilateral plate. The slider and the first telescopic rod move down along the vertical rail, and under the compression force of the first spring, the outer end face of the compensating rod is kept pressed and adapted to the quadrilateral plate.

[0016] Preferably, a rod sleeve is fixedly connected to the outer side of the output end of the first electric push rod, and a tension strip is fixedly connected to the top of the rod sleeve;

[0017] A protective box is fixedly installed on the top of the first electric push rod. The surface of the protective box has a groove, and a tension strip is slidably fitted in the groove. A limit buckle is fixedly installed on the outside of the vertical rail. The tension strip passes through the limit buckle and is fixedly connected to the slider. The limit buckle is used to limit the tension strip and provide a support point for the tension strip to avoid entanglement with other components.

[0018] The extension of the first electric push rod causes the tension bar to drive the slider and the first telescopic rod to move downwards.

[0019] Preferably, the protective mechanism includes a fixed rail, which is fixedly installed inside the processing table. A frame platform is slidably fitted inside the fixed rail.

A third electric push rod is fixedly installed on the outer end face of the output end of the second telescopic rod. A first trapezoidal block is fixedly connected to the outer side of the output end of the third electric push rod. The end of the first trapezoidal block away from the third electric push rod is fitted with the second trapezoidal block.

[0025] The inner sliding sleeve is equipped with a central rod, one end of which is fixedly connected to the second trapezoidal block.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. Through the linkage of the No. 1 electric push rod, the telescopic rod, and the tension bar, the casting mold can be driven to smoothly deflect around the fulcrum and accurately switch to a horizontal state; when the compensating rod slides along the hypotenuse of the quadrilateral plate, the No. 1 spring adaptively extends and retracts, automatically compensating for the positional deviation during the mold deflection process, ensuring a stable horizontal state; the elastic telescopic rod buffers the impact of the slider movement, avoiding mold shaking and leakage of molten casting, laying the foundation for subsequent precise casting, and adapting to the horizontal casting requirements of bolts of different specifications.

[0028] 2. During demolding, the mold can automatically flip to a vertical position, and the center rod impacts the back of the mold to help the forming bolts come out smoothly; the surface of the guide table is covered with rubber pads to buffer the impact force when the bolts come out, and avoid bumping and damaging the threads or surface structure; the guide table fits into the mold's U-shaped hole to provide stable bottom support, preventing the bolts from falling when they come out, further ensuring the integrity of the finished product and reducing processing losses.

[0029] 3. Each mechanism uses spring components for buffering and resetting. For example, spring No. 2 pushes the frame platform to automatically reset, and the elastic telescopic rod assists the slider in returning to its position, reducing manual intervention steps. The electric push rod drives the components with precise movement trajectories, and the friction adaptation and trapezoidal block extrusion structures ensure smooth action connection without the risk of jamming or deviation. After demolding, each component can quickly return to its initial state, preparing for the next casting cycle and improving the continuity and efficiency of batch processing.

[0048] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] Please see Figures 1 to 11 The present invention provides a technical solution:

[0050] Example 1: Precisely switching between horizontal casting states.

[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first electric push rod 51 of the casting mechanism 5 is fixed inside the processing table 1 by bolts, and the output end is welded with the first adapter block 52; the end of the first adapter block 52 away from the first electric push rod 51 is rotatably mounted with the first hinge seat 53 via a pin, and the outer side of the first hinge seat 53 is welded with the casting mold 54, which is made of stainless steel and has an inner cavity adapted to the shape of bolts; the top of the processing table 1 is welded with a vertical rail 55, and the slider 56 is slidably adapted inside the vertical rail 55; the outer side of the slider 56 is welded with the first telescopic rod 57, and the inside of the first telescopic rod 57 is welded with the first spring 503; the top of the casting mold 54 is welded with the second hinge seat 59, and the second hinge seat 59 is rotatably mounted with the second adapter block 58 via a pin, and the outer end face of the second adapter block 58 is welded and fixed to the first telescopic rod 57; the first telescopic rod 59... A compensating rod 502 is welded to the output end of rod 57 away from the second adapter block 58. The compensating rod 502 passes through the surface of slider 56 and telescopic rod 57. The extended end is pressed and adapted to the quadrilateral plate 2, which is a steel plate welded to the top of the processing table 1 with a beveled surface. A rod sleeve 501 is welded to the outer side of the output end of electric push rod 51. A tension strip 50, which is a safety rope, is welded to the top of electric push rod 51. A protective box 505 is welded to the top of electric push rod 51. The surface of the protective box 505 has a groove, which is slidably adapted to the tension strip 50. The other end of the tension strip 50 is welded and fixed to slider 56. An elastic telescopic rod 504 is welded to the bottom of slider 56. The bottom end of elastic telescopic rod 504 is welded to the bottom of the inner cavity of vertical rail 55.

[0052] The vertical rail 55 is fixedly installed with a limit buckle 506 on the outside, and the tension bar 50 passes through the limit buckle 506, so as to provide a support force when the tension bar 50 is stretched, and prevent it from falling off and getting tangled or colliding with the components below.

[0053] Start the first electric push rod 51. The first electric push rod 51 extends and drives the first adapter block 52 and the bottom of the casting mold 54 to move outward. At the same time, the rod sleeve 501 pulls the tension bar 50, which drives the slider 56 to move down along the vertical rail 55. The slider 56 pulls the top of the casting mold 54 down synchronously through the first telescopic rod 57 and the second adapter block 58.

[0054] When slider 56 moves down, compensation rod 502 slides along the hypotenuse of quadrilateral plate 2, and spring 503 adapts to the position of slider 56 by contracting or stretching, driving telescopic rod 57 to extend or retract; casting mold 54 deflects with adapter block 52 as fulcrum, moving outward at the bottom and inward at the top in sync until casting mold 54 is in a horizontal state; elastic telescopic rod 504 buffers the impact of slider 56 moving down, preventing mold from shaking, and provides elastic force for subsequent reset.

[0055] Example 2: Efficient casting and rapid solidification.

[0056] like Figure 1 and Figure 2 As shown, a hydraulic cylinder 3 is fixed on the processing table 1 by bolts. A casting table 4 is welded to the top of the hydraulic cylinder 3. The casting table 4 is located directly above the casting mold 54 and is used for cooling the casting liquid of the mold.

[0057] After the casting mold 54 is horizontally fixed, the hydraulic cylinder 3 is activated, and the push rod retracts to drive the casting table 4 to move down until the casting table 4 fits against the top of the casting mold 54, and heat dissipation is accelerated by the high thermal conductivity of the casting table 4.

[0058] Stainless steel molten steel is poured into the inner cavity of the casting mold 54, filling the mold cavity completely. The casting table 4 quickly dissipates heat through heat conduction, shortening the solidification time of the molten steel. During the cooling process, the casting table 4 remains in contact with the mold to prevent mold deformation from causing dimensional deviations in the parts.

[0059] Example 3: Safe release and flexible support.

[0060] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the fixed rail 61 of the protective mechanism 6 is welded inside the processing table 1, and the frame table 62 slides within the rail; a second spring 63 is welded to the outside of the frame table 62, and the other end of the second spring 63 is welded to the inner wall of the fixed rail 61; a U-shaped groove is opened on the outside of the frame table 62, and an guide table 64 slides within the U-shaped groove. The guide table is made of steel and has a rubber pad on its surface for flexible support of the accessories; a connecting block 65 is welded to the bottom of the inner cavity of the guide table 64, and the connecting block 65 slides within the bottom of the U-shaped groove, with friction between them. In addition, the guide table 64 fits into the U-shaped hole on the surface of the casting mold 54; a bending table 66 is welded to the outer end face of the fixed rail 61, and a second electric push rod 67 is fixed inside the bending table 66 by bolts; an inner sliding sleeve 68 is welded to the outside of the output end of the second electric push rod 67, and a perforated plate slides within the inner sliding sleeve 68. 69. The perforated plate 69 is slidably adapted to the fixed rail 61; a No. 3 spring 60 is welded to the outside of the perforated plate 69, and a hollow disc 606 is welded to the other end of the No. 3 spring 60; the outside of the hollow disc 606 is pressed and adapted to the connecting block 65, while the inside of the hollow disc 606 is welded and fixed to the inner sliding sleeve 68; a No. 2 telescopic rod 602 is welded to the outer end face of the frame platform 62, and the output end of the No. 2 telescopic rod 602 is welded and fixed to the perforated plate 69 through a connecting rod; a No. 3 electric push rod 603 is welded to the outside of the output end of the No. 2 telescopic rod 602, and a No. 1 trapezoidal block 604 is welded to the output end of the No. 3 electric push rod 603; a No. 1 trapezoidal block 604 is pressed and adapted to the outside of the No. 1 trapezoidal block 604, and the No. 2 trapezoidal block 605 is welded to one end of the central rod 601; the central rod 601 is slidably adapted to the inner sliding sleeve 68, and the other end faces the back of the casting mold 54.

[0061] After the parts solidify, the first electric push rod 51 is activated to reset and retract, causing the bottom of the casting mold 54 to move inward; the tension bar 50 retracts, the elastic telescopic rod 504 extends and pushes the slider 56 upward, and the first telescopic rod 57 extends and drives the top of the casting mold 54 to flip, making the mold vertical; the second electric push rod 67 is activated, and the second electric push rod 67 extends and pushes the inner sliding sleeve 68 and the perforated plate 69 to slide outward along the fixed rail 61. The perforated plate 69 drives the hollow disc 606 to press the connecting block 65 through the third spring 60; the friction between the connecting block 65 and the U-shaped groove is greater than the elastic force of the second spring 63, and the frame platform 62 moves synchronously with the connecting block 65, compressing the second spring 63, until the frame platform 62 moves to the back of the casting mold 54. The continuous extension of the second electric push rod 67 causes the guide platform 64 to extend outward from the frame platform 62 and engage with the U-shaped hole on the surface of the casting mold 54, providing bottom support for the parts to be removed.

[0062] Start the third electric push rod 603. The third electric push rod 603 extends and pushes the first trapezoidal block 604 to squeeze the second trapezoidal block 605. This drives the center rod 601 to move outward along the inner sliding sleeve 68 and impact the back of the casting mold 54. After the mold is impacted, the internal molding parts slide out and fall onto the rubber pad of the guide table 64 to avoid damage to the parts. After demolding is completed, the second electric push rod 67 resets and retracts, and the second spring 63 extends and pushes the frame table 62 to reset. The operator can then remove the parts from the guide table 64.

[0063] The working principle of this invention is as follows: When the first electric push rod 51 extends, it drives the first adapter block 52 and the casting mold 54 hinged by the first hinge seat 53 to move. At the same time, the tension bar 50 pulls the slider 56 down along the vertical rail 55. The slider 56 drives the top of the casting mold 54 to move down synchronously through the first telescopic rod 57 and the second adapter block 58. However, during the process of the first telescopic rod 57 moving down along the vertical rail 55, the first spring 503 connected to the output end of the first telescopic rod 57 will continuously provide a contraction force to the first telescopic rod 57. One end of the output end of the first telescopic rod 57 is connected to the compensating rod 502, and the other end of the compensating rod 502 is pressed against the quadrilateral plate 2. Therefore, when the first telescopic rod 57 is at the top of the vertical rail 55, the compensating rod 502 is pressed against the top inclined side of the quadrilateral plate 2, causing the first spring 503 to stretch and the first telescopic rod 57 to extend. However, as the tension bar 50 pulls the slider 56 down along the vertical rail 55, the compensating rod 502 slides down along the inclined side of the quadrilateral plate 2, the first spring 503 contracts accordingly, and the first telescopic rod 57 contracts. Finally, the first electric push rod 51 drives the bottom of the casting mold 54 to move outward, while the first telescopic rod 57 drives the top of the casting mold 54 to move inward and deflects it with the first adapter block 52 as the fulcrum, so that the casting mold 54 is in a horizontal state.

[0064] After the mold is horizontally fixed, molten metal is poured into it; hydraulic cylinder 3 pushes casting platform 4 down to fit the bottom of casting mold 54, and the heat dissipation function of casting platform 4 accelerates the cooling of molten metal and shortens the solidification time. Elastic telescopic rod 504 can buffer the impact of sliding block 56 movement, ensure the mold positioning process is stable, ensure no leakage of molten metal during casting, and at the same time, it can reset sliding block 56.

[0065] After the marine components are cast, the first electric push rod 51 is reset and retracted. This pushes the bottom of the casting mold 54 inward through the first adapter block 52, and the tension bar 50 retracts accordingly. Simultaneously, under the elastic force of the elastic telescopic rod 504, the slider 56 drives the first telescopic rod 57 to move upward along the vertical rail 55. As the slider 56 moves upward, the first telescopic rod 57 moves upward as well. The compensating rod 502 remains pressed against the quadrilateral plate 2, causing the first telescopic rod 57 to gradually extend. This causes the top of the casting mold 54 to rotate around the second hinge seat 59 until the first telescopic rod 57 moves to the middle section of the vertical rail 55. At this point, the casting mold 54 is tilted, making it easier for the operator to remove the solidified components inside.

[0066] The second electric push rod 67 extends, pushing the inner sliding sleeve 68 and the perforated plate 69 to slide forward along the fixed rail 61. The perforated plate 69 drives the hollow disc 606 to move through the third spring 60. The hollow disc 606 presses against the connecting block 65. There is friction between the connecting block 65 and the U-shaped groove, and the friction force is greater than the elastic force of the second spring 63. Therefore, the hollow disc 606 will push the frame platform 62 outward through the connecting block 65 and compress the second spring 63 until the frame platform 62 moves to the back of the vertical casting mold 54. Then, the second electric push rod 67 is still in the extended state. Then, the hollow disc 606 drives the connecting block 65, causing the guide platform 64 to slide along the U-shaped groove of the frame platform 62. Finally, the guide platform 64 fits into the U-shaped hole on the surface of the casting mold 54 and passes through the casting mold 54, providing bottom support for the part that is about to be removed. Spring 63 can buffer the impact of the frame platform 62 moving, ensure the precise docking of the guide platform 64 with the mold, and realize the reset of the frame platform 62.

[0067] As the inner sliding sleeve 68 and the perforated plate 69 move outward, the second telescopic rod 602, which is connected to the outside of the perforated plate 69 via a connecting rod, will retract accordingly. The corresponding central rod 601, which is slidably adapted to the inside of the inner sliding sleeve 68, will also move outward. Then, the third electric push rod 603 is activated, causing the first trapezoidal block 604, which is connected to its output end, to move towards the center and squeeze the second trapezoidal block 605. The squeezed second trapezoidal block 605 will drive the central rod 601 to move outward again and impact the back of the casting mold 54. As a result, the molded parts inside the casting mold 54 will slide into the guide table 64 due to the impact. The flexible support of the guide table 64 will prevent the parts from directly impacting or colliding with each other.

[0068] Simultaneously, the center rod 601 further adjusts the position of the guide table 64, ensuring that the guide table 64 passes through the U-shaped groove on the surface of the casting mold 54, and ensuring that the part falls smoothly onto the guide table 64. The operator can then remove the part from the guide table 64 without having to remove it from the casting mold 54.

Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
