Description

Technical Field

[0001] This invention relates to the field of excavator parts die-casting equipment technology, specifically to a horizontal parting static pressure casting auxiliary device. Background Technology

[0002] Horizontal parting static pressure casting auxiliary equipment refers to the collective term for supporting equipment used in static pressure casting production lines employing horizontal parting boxless or flaked molding processes. This equipment, excluding the main molding and casting core units, ensures the smooth operation of processes such as sand mold preparation, conveying, positioning, and casting removal. It typically includes hydraulic or pneumatic compaction mechanisms. Its function is to ensure precise alignment, stable transfer, and reliable sealing of the upper and lower sand molds after static pressure molding, thereby effectively preventing defects such as misalignment and arcing, improving casting dimensional accuracy and production efficiency. It is an indispensable key support equipment for achieving automated and stable production in horizontal parting static pressure casting.

[0003] Existing die-casting equipment generally uses a support method where the workpiece is in direct hard contact with the rigid machining table during the compaction operation. When the pressure head applies high pressure, the huge concentrated stress can easily cause indentations, cracks, or even breakage on the surface of brittle or precision-machined workpieces. At the same time, it may also cause wear, deformation, or local collapse of the working surface of the machining table due to repeated impacts. This direct contact not only reduces the product yield and mold life, but also increases the frequency of equipment maintenance and production costs, which seriously restricts the application of die casting technology in the processing of thin-walled parts, high-precision parts, and vulnerable materials, and is inconvenient to use. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a horizontal parting static pressure casting auxiliary device, which can effectively solve the problem that the existing die casting device adopts the support method of direct hard contact between the workpiece and the processing table. The concentrated stress during high pressure can easily lead to workpiece surface damage and worktable wear and deformation. This direct impact not only reduces the product yield and mold life, but also increases maintenance costs, which seriously restricts its convenient application in precision and wear parts processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an auxiliary device for horizontal parting static pressure casting, including a processing table. The inner cavity of the processing table is provided with a support assembly, which includes a rotating rod. Threaded rods are rotatably connected to both sides of the inner cavity of the processing table. Synchronous pulleys are respectively installed on the outer surfaces of the threaded rods and the rotating rods, and several synchronous pulleys are connected by a synchronous belt drive. A threaded plate is threadedly connected to the outer surface of the threaded rod, and both sides of the threaded plate are slidably connected to the processing table. A top plate is fixedly connected to the top of the threaded plate, and a processing assembly is provided on the top of the processing table.

[0006] Furthermore, a clamping plate is fixedly connected to one side of the movable plate, the movable plate is slidably connected to the inner cavity of the processing table, a top rod is slidably connected to the inner cavity of the processing table, and a first transmission gear is fixedly connected to the outer surface of the rotating rod.

[0007] Furthermore, toothed plates are fixedly connected to one side of the movable plate and the top rod, and the toothed plates mesh with the first transmission gear. A first guide frame is slidably connected to the left side of the processing table, one end of the top rod is fixedly connected to the first guide frame, and an installation rod is rotatably connected to the left side of the processing table.

[0008] Furthermore, two push plates are fixedly connected to the outer surface of the mounting rod, and a connecting rod is fixedly connected to one side of each push plate. One side of the first guide frame is movably connected to the connecting rod.

[0009] Furthermore, a first cylinder is fixedly connected to the inner cavity of the processing table, and a positioning rod is fixedly connected to the output end of the first cylinder. One end of the positioning rod extends through to the outer side of the inner cavity of the processing table, and one side of the push plate is movably connected to the positioning rod.

[0010] Furthermore, a protective box is fixedly connected to the left side of the processing table. A round rod is rotatably connected to the inner cavity of the protective box and one side of the processing table. A second transmission gear is fixedly connected to the outer surface of the round rod and the mounting rod, and the two second transmission gears mesh with each other. A running plate is fixedly connected to the outer surface of the round rod.

[0011] Furthermore, a fixing rod is fixedly connected to one side of the running plate, and two other second guide frames are slidably connected to the left side of the processing table. One side of the second guide frame is movably connected to the fixing rod, and a clamping plate is fixedly connected to one side of the second guide frame.

[0012] Furthermore, the processing assembly includes two electric guide rails, one side of which is equipped with a slide plate, and the other side of which is fixedly connected to a second cylinder.

[0013] Furthermore, the output ends of the two second cylinders are respectively fixedly connected to a pressure plate and a flow divider plate, and an air compressor is installed on one side of the slide plate. The air supply end of the air compressor is connected to the flow divider plate through a hose.

[0014] Furthermore, a PLC control device is installed on one side of the processing table, and vision sensors are installed on both sides of the processing table.

[0015] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention utilizes the top plate, clamping plate, and clamping plate in the support assembly to form a working process that combines bottom lifting with lateral limiting. Before the clamping plate and clamping plate clamp and arrange the sides of the workpiece, the top plate moves upward first and provides support to the bottom of the workpiece, allowing the workpiece to detach from the worktable surface and avoiding direct contact between the two. Subsequently, the clamping plate and clamping plate correct and fix the position of the sides of the workpiece, thus eliminating the need for the user to manually arrange and position the sides of the workpiece. This method of lifting first and then clamping ensures the accuracy of the workpiece's placement and disperses the concentrated stress during downward pressure through bottom support, effectively preventing the workpiece from being indented or damaged due to collision with the worktable, and improving the applicability of the device to fragile workpieces.

[0016] II. This invention utilizes the first cylinder, connecting rod, mounting rod, and first guide frame in the support assembly to achieve a linkage effect of a single power source driving multiple actuators. The first cylinder serves as the sole power input, transmitting power through the swinging of the connecting rod and mounting rod, in conjunction with the sliding guidance of the first guide frame, synchronously driving the clamping plate, clamping plate, and top plate to move in a predetermined sequence. This eliminates the need for a separate drive device for each action, reducing the number of power components, lowering equipment energy consumption and manufacturing costs. Furthermore, relying on the inherent constraints of mechanical transmission, it ensures the timing and positional matching of the movements of each component, making clamping, lifting, and other actions smooth and reliable, and avoiding positioning deviations or impact problems caused by asynchronous control of multiple power sources.

[0027] refer to Figures 1-8A PLC control device 11 is installed on one side of the processing table 1. This PLC control device 11 is a mechatronics system that uses a programmable logic controller as its core. It collects real-time signals from buttons, sensors, and other field sources through input modules. The central processing unit performs logical operations, sequential control, timing counting, and data processing according to a user-pre-written program.

The PLC control device 11 is electrically connected to the first cylinder 214, the second cylinder 33, the air compressor 35, the electric guide rail 31, and the vision sensor 12.

Then, the image data is analyzed, identified, and parsed by a built-in or external processor to obtain feature information such as the object's position, size, shape, surface defects, or color. In the field of industrial automation, it is often installed above or to the side of the processing table to monitor the placement posture, clamping status, and compaction effect of the workpiece in real time.

[0028] Specifically, after the user places the processing mold into the excavator parts model and places it on the processing table 1, the first cylinder 214 is activated to push the positioning rod 215 to move left and right. The positioning rod 215 drives the push plate 212 and the mounting rod 211 to swing. The mounting rod 211 causes the second transmission gear 218 to mesh and rotate. At the same time, the push plate 212 slides in the first guide frame 210 via the connecting rod 213. The first guide frame 210 pushes the top rod 27 and one of the toothed plates 28 to move. The toothed plate 28 meshes with the first transmission gear 29, causing the first transmission gear 29, the rotating rod 21, and the synchronous wheel 23 to rotate. The first transmission gear 29 then pushes the other toothed plate 28 to drive the moving plate 26 and the clamping plate 223 to move. Meanwhile, the second transmission gear 218 drives the round rod 217 and the running plate 219 to swing. The running plate 219 is connected to the fixed rod 22 The 0 slides within the second guide frame 221, pushing the second guide frame 221 and the clamping plate 222 to move, causing the clamping plate 222 and the clamping plate 223 to move relative to or away from each other to limit and arrange the position of the workpiece; during this process, the synchronous wheel 23 also drives the threaded rod 22 to rotate, causing the threaded plate 24 and the top plate 25 to move upward to lift and support the bottom of the workpiece; then the electric guide rail 31 is activated to drive the slide plate 32 to move back and forth, one second cylinder 33 is activated to push the flow divider plate 34 down, and the air compressor 35 is activated to deliver airflow to the flow divider plate 34 to complete the pre-compactment, and finally another second cylinder 33 is activated to push the pressure plate 36 to compact the workpiece. In this way, through the action of the top plate 25, the workpiece is prevented from directly contacting the surface of the processing table 1 during the die casting process, avoiding damage during die casting and facilitating subsequent use.
