Description
Technical Field
[0001] This utility model relates to the field of die casting mold design and manufacturing technology, specifically a die casting mold for a two-cylinder outboard motor. Background Technology
[0002] With the development of lightweight ships and the increasing precision of small power equipment, the die-casting process for two-cylinder outboard engines places increasingly higher demands on mold stability and molding accuracy. Traditional die-casting molds, due to unstable clamping and insufficient support, suffer from defects (such as dimensional deviations and surface damage) that can no longer meet high-performance requirements.
[0003] The clamping structure relies on friction on a single plane, resulting in poor anti-slip capability. The mold is prone to displacement due to hydraulic impact or vibration. The metal clamping plates directly press against the mold surface, causing scratches or localized deformation, which affects the mold's lifespan and molding accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a die-casting mold for a two-cylinder outboard motor, addressing the problems of a clamping structure relying on single-plane friction, poor anti-slip capability, and mold displacement due to hydraulic impact or vibration. It also addresses the issues of metal clamps directly pressing against the mold surface, leading to scratches or localized deformation, thus affecting mold life and molding accuracy.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a die-casting mold for a two-cylinder outboard motor, comprising a worktable, a fixed plate, a fixed column, and a hydraulic assembly. The worktable has a fixed plate on its surface, and a fixed column is fixedly connected to the surface of the worktable. The hydraulic assembly is mounted on the surface of the fixed plate. The worktable surface has a clamping structure, which includes a telescopic column. One end of the telescopic column is fixedly connected to the surface of the fixed plate. A groove is formed on the surface of the worktable, and a clamping plate is slidably connected to the inner wall of the groove. A double-acting screw is rotatably connected to the inner wall of the groove, and the arc surface of the double-acting screw is threadedly connected to the surface of the clamping plate. A motor is mounted on the surface of the worktable, and the output end of the motor is threadedly connected to one end of the double-acting screw. The telescopic column connects the fixed plate and the clamping plate, assisting the clamping plate in moving in a straight line, preventing the clamping plate from shifting due to the rotation of the double-acting screw, and improving clamping accuracy. The motor serves as the power source for the clamping structure, driving the double-acting screw to rotate through its output end, achieving automated opening and closing of the clamping plate, replacing manual operation to improve efficiency and clamping force uniformity. The sliding groove design limits the sliding trajectory of the clamping plates, preventing them from tilting or misaligning during movement and ensuring the mold is clamped in the same plane. The bidirectional lead screw design allows for simultaneous or reverse movement of the two clamping plates, enabling adaptive clamping of molds of different sizes and ensuring alignment between the mold center and the hydraulic components. The clamping plates directly contact and clamp both sides of the mold, using symmetrically distributed clamping forces to prevent mold displacement during die casting and ensure molding accuracy.
[0006] Furthermore, the surface of the clamping plate is fixedly connected with protrusions, the cross-section of which is rectangular. The protrusions increase the contact area between the clamping plate and the mold, improve friction, and prevent the mold from sliding due to hydraulic impact. The rectangular cross-section is designed to fit the shape of the mold edge.
[0007] Furthermore, a protective pad, made of rubber, is fixedly connected to the surface of the clamping plate. The protective pad, made of rubber, buffers the rigid collision between the clamping plate and the mold, preventing scratches on the mold surface, while also further enhancing friction and improving clamping stability.
[0008] Furthermore, the surface of the fixed column is provided with a stabilizing structure, which includes a connecting column. The surface of the connecting column is fixedly connected to the surface of the fixed column. A groove is formed on the surface of the connecting column, and a sliding plate is slidably connected to the inner wall of the groove. A bidirectional screw is rotatably connected to the inner wall of the groove, and a rotating plate is fixedly connected to one end of the bidirectional screw. A fixing block is fixedly connected to the surface of the sliding plate. The connecting column is fixed to the surface of the fixed column, providing an installation carrier for the stabilizing structure. The groove accommodates the sliding plate and the bidirectional screw. The groove limits the movement direction of the sliding plate, ensuring that the fixing block moves laterally along the mold and avoiding positioning deviations caused by shaking. The bidirectional screw is driven to rotate by the rotating plate, causing the two sliding plates to move synchronously closer to or away from the mold, achieving symmetrical lateral reinforcement of the mold. The sliding plate connects the bidirectional screw and the fixing block, converting the rotational motion of the screw into linear motion, pushing the fixing block to fit against the side of the mold. The fixing block contacts the side of the mold, providing lateral support to counteract the lateral force during die casting and preventing mold deformation or displacement, which is especially suitable for large or thin-walled molds. The rotating plate provides a point of leverage for manual operation, allowing operators to easily adjust the position of the fixed block by rotation. The structure is simple and the adjustment is flexible.
[0009] Furthermore, a pad made of rubber is fixedly connected to the surface of the fixing block. The use of rubber pads prevents surface damage caused by rigid contact between the fixing block and the mold, while also increasing friction on the contact surface and improving the stability of the lateral support.
[0010] Furthermore, the surface of the rotating plate is rotatably connected with bolts, one end of which is threadedly connected to the surface of the connecting column. This bolt arrangement allows the bolts to be tightened after the fixing block is adjusted into position, so that their ends abut against the surface of the connecting column, locking the rotating plate in place and preventing the bidirectional screw from loosening due to vibration.
[0011] This utility model has the following beneficial effects: This invention utilizes a clamping structure. A motor-driven bidirectional lead screw within the clamping structure moves the clamping plates within the slide groove in opposite directions, achieving rapid and automated clamping of the mold. The cooperation between the telescopic column and the slide groove limits the offset of the clamping plates, ensuring the straightness of the clamping trajectory. The protrusions on the clamping plate surface and the rubber protective pads work together to increase friction and buffer rigid impacts. This design improves the accuracy and stability of mold fixing, avoids errors from manual operation, reduces the risk of mold surface damage, and provides a reliable foundation for die casting.
[0012] This invention utilizes a stabilizing structure. A rotating plate within the stabilizing structure drives a bidirectional screw, causing the sliding plate and fixing block to move along a groove. This allows the rubber pad to conform to the side of the mold, providing adjustable lateral support. Tightening the bolts locks the rotating plate in place, preventing the support from loosening due to vibration. This design uses flexible support to counteract lateral forces during die-casting, effectively preventing deformation and displacement of thin-walled or large molds. It also avoids surface scratches caused by rigid contact, significantly improving the structural stability and molding quality of the mold under high-pressure conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 - Figure 5 As shown, this utility model is a die-casting mold for a two-cylinder outboard motor, including a worktable 1, a fixed plate 2, a fixed column 3, and a hydraulic assembly 4. The fixed plate 2 is provided on the surface of the worktable 1, and the fixed column 3 is fixedly connected to the surface of the worktable 1. The hydraulic assembly 4 is installed on the surface of the fixed plate 2. A clamping structure 5 is provided on the surface of the worktable 1, including a telescopic column 51. One end of the telescopic column 51 is fixedly connected to the surface of the fixed plate 2. A sliding groove 53 is formed on the surface of the worktable 1, and a clamping plate 55 is slidably connected to the inner wall of the sliding groove 53. A double-acting screw 54 is rotatably connected to the inner wall of the sliding groove 53, and the arc surface of the double-acting screw 54 is threadedly connected to the surface of the clamping plate 55. A motor 52 is installed on the surface of the worktable 1, and the output end of the motor 52 is threadedly connected to one end of the double-acting screw 54. The telescopic column 51 connects the fixed plate 2 and the clamping plate 55, assists the clamping plate 55 in moving in a straight line, prevents the clamping plate from shifting due to the rotation of the double-acting screw 54, and improves clamping accuracy. The motor 52 serves as the power source for the clamping structure, driving the bidirectional lead screw 54 to rotate via its output end, thus automating the opening and closing of the clamping plates 55. This replaces manual operation, improving efficiency and the uniformity of clamping force. The slide groove 53 limits the sliding trajectory of the clamping plates 55, preventing them from tilting or misaligning during movement and ensuring the mold is clamped in the same plane. The bidirectional lead screw 54 enables the two clamping plates 55 to move simultaneously in opposite directions via forward and reverse rotation, achieving adaptive clamping for molds of different sizes and ensuring alignment between the mold center and the hydraulic component 4. The clamping plates 55 directly contact and clamp both sides of the mold, preventing displacement during die casting through symmetrically distributed clamping force and ensuring molding accuracy.
[0019] The surface of the clamping plate 55 is fixedly connected with a protrusion 56, the cross-section of which is rectangular. The protrusion 56 increases the contact area between the clamping plate 55 and the mold, improves friction, and prevents the mold from sliding due to hydraulic impact. The cross-section is designed to fit the shape of the mold edge.
[0020] A protective pad 57, made of rubber, is fixedly connected to the surface of the clamping plate 55. The protective pad 57, made of rubber, buffers the rigid collision between the clamping plate 55 and the mold, preventing scratches on the mold surface, while further enhancing friction and improving clamping stability.
[0021] The surface of the fixed column 3 is provided with a stabilizing structure 6, which includes a connecting column 61. The surface of the connecting column 61 is fixedly connected to the surface of the fixed column 3. A groove 62 is formed on the surface of the connecting column 61. A sliding plate 64 is slidably connected to the inner wall of the groove 62. A bidirectional screw 63 is rotatably connected to the inner wall of the groove 62. One end of the bidirectional screw 63 is fixedly connected to a rotating plate 66. A fixing block 65 is fixedly connected to the surface of the sliding plate 64. The connecting column 61 is fixed to the surface of the fixed column 3, providing a mounting carrier for the stabilizing structure. The groove 62 accommodates the sliding plate 64 and the bidirectional screw 63. The groove 62 limits the movement direction of the sliding plate 64, ensuring that the fixing block 65 moves laterally along the mold and avoiding positioning deviations caused by shaking. The bidirectional screw 63 is driven to rotate by the rotating plate 66, causing the two sliding plates 64 to move synchronously closer to or further away from the mold, achieving symmetrical lateral reinforcement of the mold. The sliding plate 64 connects the bidirectional screw 63 and the fixing block 65, converting the screw's rotational motion into linear motion, pushing the fixing block 65 to conform to the mold side. The fixing block 65, by contacting the mold side, provides lateral support to counteract the lateral forces during die casting, preventing mold deformation or displacement, making it particularly suitable for large or thin-walled molds. The rotating plate 66 provides a point of leverage for manual operation, allowing operators to easily adjust the position of the fixing block 65 by rotation; the structure is simple and the adjustment is flexible.
[0022] A pad 68, made of rubber, is fixedly connected to the surface of the fixing block 65. The pad 68 is designed with rubber to prevent surface damage caused by rigid contact between the fixing block 65 and the mold, while also increasing the friction of the contact surface and improving the stability of the lateral support.
[0023] Bolts 67 are rotatably connected to the surface of the rotating plate 66, with one end of the bolts 67 threadedly connected to the surface of the connecting column 61. The bolts 67 are designed so that after the fixing block 65 is adjusted into place, the bolts can be tightened so that their ends abut against the surface of the connecting column 61, locking the position of the rotating plate 66 and preventing the bidirectional screw 63 from loosening due to vibration.
[0024] The die-casting mold for the outboard motor's second cylinder block is placed on the surface of the workbench 1, with a base support provided by the fixed plate 2 and the fixed column 3. The motor 52 in the clamping structure 5 is activated, driving the bidirectional lead screw 54 to rotate. This causes the clamping plates 55 in the slide groove 53 to move towards each other along the lead screw until the clamping plates 55 clamp both sides of the mold, completing the initial positioning of the mold. The telescopic column 51 connects the fixed plate 2 and the clamping plates 55, assisting the clamping plates 55 to move in a straight line, preventing the clamping plates from shifting due to the rotation of the bidirectional lead screw 54, and improving clamping accuracy. The motor 52 serves as the power source for the clamping structure, driving the bidirectional lead screw 54 to rotate through its output end, achieving automated opening and closing of the clamping plates 55, replacing manual operation to improve efficiency and clamping force uniformity. The slide groove 53 limits the sliding trajectory of the clamping plates 55, preventing the clamping plates from tilting or misaligning during movement, ensuring that the mold is clamped in the same plane. The bidirectional lead screw 54 enables the two clamping plates 55 to move simultaneously in opposite directions via forward and reverse rotation, achieving adaptive clamping for molds of different sizes and ensuring alignment between the mold center and the hydraulic component 4. The clamping plates 55 directly contact and clamp both sides of the mold, preventing displacement during die casting through symmetrically distributed clamping force, thus ensuring molding accuracy. The protrusions 56 increase the contact area between the clamping plates 55 and the mold, improving friction and preventing slippage due to hydraulic shock; their rectangular cross-section adapts to the mold edge shape. The protective pads 57, made of rubber, buffer the rigid collision between the clamping plates 55 and the mold, preventing scratches on the mold surface and further enhancing friction and clamping stability. By designing the clamping structure 5, the reliance on a single plane for friction is minimized, as this results in poor anti-slip capability and makes the mold prone to displacement due to hydraulic shock or vibration. Direct pressure from the metal clamping plates on the mold surface can cause scratches or localized deformation, affecting mold life and molding accuracy. If the mold height is high or the impact force during mold closing is large, the stabilizing structure 6 can be adjusted: rotating the rotating plate 66 drives the bidirectional screw 63 to rotate, causing the sliding plate 64 and the fixing block 65 in the groove 62 to move towards the mold. The pad 68 then abuts against the side of the mold, further improving stability. After adjustment, tighten the bolt 67 to fix the rotating plate 66. The connecting column 61 is fixed to the surface of the fixing column 3, providing an installation carrier for the stabilizing structure. The groove 62 accommodates the sliding plate 64 and the bidirectional screw 63. The groove 62 limits the movement direction of the sliding plate 64, ensuring that the fixing block 65 moves laterally along the mold, avoiding positioning deviations caused by shaking. The bidirectional screw 63 is driven to rotate by the rotating plate 66, causing the two sliding plates 64 to move synchronously closer to or further away from the mold, achieving symmetrical lateral reinforcement of the mold. The sliding plate 64 connects the bidirectional screw 63 and the fixing block 65, converting the screw's rotational motion into linear motion, pushing the fixing block 65 to conform to the side of the mold. The fixing block 65 is designed to contact the side of the mold, providing lateral support to counteract lateral forces during die casting and prevent mold deformation or displacement, making it particularly suitable for large or thin-walled molds. The rotating plate 66 provides a point of leverage for manual operation, allowing operators to easily adjust the position of the fixing block 65 by rotation; the structure is simple and the adjustment is flexible. The bolt 67, after the fixing block 65 is adjusted into position, allows tightening the bolt so that its end abuts against the surface of the connecting column 61, locking the rotating plate 66 and preventing the bidirectional screw 63 from loosening due to vibration. The pad 68, made of rubber, prevents surface damage caused by rigid contact between the fixing block 65 and the mold, while increasing friction on the contact surface and improving the stability of the lateral support. By incorporating the stabilizing structure 6, it addresses the issue that traditional die casting molds rely solely on vertical clamping, neglecting the impact of lateral forces on thin-walled or large molds, which can lead to dimensional deviations or structural deformation after molding.
