Description

Technical Field

[0001] This utility model belongs to the technical field of vibratory core removal equipment, and in particular relates to a vibratory core removal machine that is easy to discharge. Background Technology

[0002] Vibratory core removers are key equipment in the foundry industry used to remove core sand from the inside and surface of castings. They separate the core sand from the casting body through vibration force, ensuring the accuracy of subsequent processing of the casting. The clamping assembly, as the core component of the vibratory core remover, directly affects the ease of feeding, positioning stability and casting protection effect.

[0003] Chinese patent application CN214557306U discloses a novel vibratory core removal machine, including a casting support. The support includes a cylindrical component vertically mounted on a worktable. A pressure plate is mounted on the upper end of the cylindrical component, and an elastic element is fixedly mounted on the upper surface of the pressure plate. The elastic element has a cylindrical structure and a through hole in its center. A screw hole is located at the center of the upper surface of the cylindrical component. The pressure plate is fixed to the cylindrical component by bolts passing through it, and the outer end of the bolts can be accommodated by the through hole of the elastic element. The advantage is that the elastic element contacts the casting, achieving vibration reduction during the vibratory core removal process in the longitudinal direction, and increasing the frictional force on the casting in the lateral direction, preventing lateral displacement due to vibration. This improves the positioning accuracy of the casting and avoids the production of defective parts.

[0004] While this patent improves positioning accuracy and reduces surface damage by installing an elastic element on the upper part of the pressure plate to achieve longitudinal vibration reduction and lateral friction increase during vibration, thus preventing casting displacement, the structure of its casting support is fixed. The support structure formed by the elastic element, pressure plate, and columnar element cannot be flexibly replaced or adjusted according to the different shapes, sizes, and materials of the casting. When dealing with irregularly shaped or irregularly contoured castings, or castings made of different materials with different hardness and surface properties, the fixed support structure is difficult to form a suitable contact support surface. This results in either failure to achieve stable clamping and positioning, or weakened vibration reduction effect, uneven stress on the casting, or even damage to the casting due to improper contact method. This limits the adaptability of the equipment and makes it difficult to meet diverse production needs.

[0005] To address these issues, we provide a vibratory core remover that facilitates material feeding. Summary of the Invention

[0006] The purpose of this utility model is to provide a vibratory core remover that facilitates material feeding. By cooperating with the clamping components and the worktable, it solves the problem that the clamps in the prior art cannot be quickly changed according to the shape of the casting.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a vibratory core remover for easy material feeding, comprising a worktable, a clamping assembly on the top of the worktable, the clamping assembly including a motor, one side of the motor being fixedly connected to the worktable, a lead screw being fixedly connected to the output end of the motor, a movable plate being threadedly connected to the surface of the lead screw, a clamping plate being slidably connected to the inner side of the movable plate, an insert block being engaged with the inner cavity of the clamping plate, a connecting plate being fixedly connected to the other side of the insert block, both sides of the connecting plate being slidably connected to the movable plate, and a connecting plate being fixedly connected to the rear side of the connecting plate. The device is equipped with a pull rod, and a first spring is provided on both sides of the pull rod. One side of the first spring is fixedly connected to the moving plate. There are three insert blocks, which are arranged in an array on one side of the connecting plate. They can lock and fix the clamping plate from multiple points, making the connection between the clamping plate and the moving plate more evenly stressed and avoiding local stress concentration caused by single-point locking. The top side of the insert block is inclined and has a guiding function. When installing the clamping plate, simply align the clamping plate and insert it. The insert block will automatically retract and avoid it. The other side of the pull rod passes through the inner cavity of the moving plate and is fixedly connected to a pull plate, which makes it convenient for the operator to quickly grab and apply pulling force.

[0008] The present invention is further configured such that the surface of the pull rod is provided with an anti-loosening component, the anti-loosening component includes a locking block, the bottom of the locking block is fixedly connected to the pull rod, a locking plate is engaged with the inner side of the locking block, both sides of the locking plate are slidably connected to a moving plate, a moving rod is fixedly connected to the top of the locking plate, a second spring is provided on the surface of the moving rod, the top of the second spring is fixedly connected to the moving plate, and there are multiple locking blocks evenly distributed on the surface of the pull rod, which can engage and limit the locking plate from multiple points on the surface of the pull rod, making the locking force of the pull rod more balanced, avoiding local stress concentration caused by a single locking block bearing all the locking pressure, and reducing the wear of the locking block and the locking plate.

[0009] The present invention is further configured such that a vibration assembly is provided on the top of the workbench, the vibration assembly includes a cylinder, the bottom of the cylinder is fixedly connected to the workbench, a push rod is slidably connected to the inner cavity of the cylinder, a fixed plate is fixedly connected to the bottom of the push rod, both sides of the fixed plate are slidably connected to the workbench, and a pneumatic vibrator is fixedly connected to the bottom of the fixed plate. The arrangement of three pneumatic vibrators can form multi-point coordinated vibration, so that the vibration force is more evenly distributed on the surface of the casting and has a wider coverage area. It can act on the core sand in different areas of the casting at the same time, promoting the rapid crushing and falling off of the core sand.

[0010] The present invention is further configured such that a support frame is fixedly connected to the bottom of the workbench, and there are two support frames. The two support frames are symmetrically distributed at the bottom of the workbench, which can evenly transfer the weight of the workbench and the clamping and vibration components above to the ground, and avoid the workbench tilting or deforming due to unilateral force.

[0011] The present invention is further configured such that guide grooves are provided on both sides of the inner cavity of the movable plate, and guide sliders are slidably connected to the inner cavity of the guide grooves.

[0014] The present invention is further configured such that limit rods are slidably connected to both sides of the fixed plate, and both sides of the limit rods are fixedly connected to the worktable, and the limit rods can provide precise positioning and guidance for the fixed plate.

[0015] The present invention has the following beneficial effects.

[0016] 1. The clamping assembly of this utility model uses a motor to drive the lead screw to rotate, which in turn moves the moving plate along the lead screw axis. There is no need for manual adjustment of the clamping distance. The clamping plate and the moving plate adopt a sliding fit structure, which is combined with the locking and fixing method of the insert block and the inner cavity of the clamping plate. Furthermore, a linkage mechanism is formed by the connecting plate, the pull rod and the first spring, which makes the disassembly and replacement of the clamping plate extremely convenient: no additional tools are needed. Just pull the pull rod manually to drive the connecting plate to move synchronously, thereby pulling the insert block out of the locking cavity of the clamping plate, releasing the clamping plate from its fixed restriction. Then, the clamping plate can be easily removed along the sliding trajectory on the inner side of the moving plate. When installing a new clamping plate, simply slide the appropriate clamping plate into the corresponding groove of the moving plate to complete the installation. The entire disassembly and assembly process is smooth, time-saving and labor-saving, which greatly reduces the difficulty and time cost of changing the type of operation.

[0017] 2. The anti-loosening component of this utility model, through the interlocking of the locking block and the locking plate, combined with the elastic tension of the second spring, can form a stable limiting fixation for the pull rod, effectively preventing the pull rod from moving unexpectedly due to the high-frequency vibration of the equipment during the core removal process. This prevents the insert block from detaching from the inner cavity of the clamping plate, ensuring that the clamping plate always maintains a stable fixed state, eliminating casting displacement caused by loose clamping, and ensuring the stability and safety of the core removal operation.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5 This utility model is a vibratory core remover that facilitates material feeding.

[0026] Specifically: There are three insert blocks 205, which are arrayed on one side of the connecting plate 206. They can lock and fix the clamping plate 204 from multiple points, making the connection between the clamping plate 204 and the moving plate 203 more evenly stressed and avoiding local stress concentration caused by single-point locking. The top side of the insert block 205 is inclined and has a guiding function. When installing the clamping plate 204, simply insert the clamping plate 204 into the correct position, and the insert block 205 will automatically retract to avoid it. The other side of the pull rod 207 passes through the inner cavity of the moving plate 203 and is fixedly connected to a pull plate, which makes it convenient for operators to quickly grab and apply pulling force.

[0027] Please see Figure 1-5 The pull rod 207 has an anti-loosening component 3 on its surface. The anti-loosening component 3 includes a locking block 301. The bottom of the locking block 301 is fixedly connected to the pull rod 207. A locking plate 302 is engaged with the inner side of the locking block 301. Both sides of the locking plate 302 are slidably connected to the moving plate 203. A moving rod 303 is fixedly connected to the top of the locking plate 302. A second spring 304 is provided on the surface of the moving rod 303. The top of the second spring 304 is fixedly connected to the moving plate 203. The top of the worktable 1 has a vibration component 4. The vibration component 4 includes a cylinder 401. The bottom of the cylinder 401 is fixedly connected to the worktable 1. A push rod 402 is slidably connected to the inner cavity of the cylinder 401. A fixing plate 403 is fixedly connected to the bottom of the push rod 402. Both sides of the fixed plate 403 are slidably connected to the workbench 1. A pneumatic vibrator 404 is fixedly connected to the bottom of the fixed plate 403. A support frame 5 is fixedly connected to the bottom of the workbench 1. There are two support frames 5. Guide grooves 6 are opened on both sides of the inner cavity of the movable plate 203. A guide slider 7 is slidably connected to the inner cavity of the guide groove 6. The other side of the guide slider 7 is fixedly connected to the clamping plate 204. A limit groove 8 is opened on one side of the inner cavity of the movable plate 203. The inner cavity of the limit groove 8 is slidably connected to the connecting plate 206. A buckle 9 is provided on one side of the movable plate 203. One side of the buckle 9 is rotatably connected to the movable rod 303. Limit rods 10 are slidably connected to both sides of the fixed plate 403. Both sides of the limit rods 10 are fixedly connected to the workbench 1.

[0028] Specifically: Multiple locking blocks 301 are evenly distributed on the surface of the pull rod 207, allowing them to engage and limit the locking plate 302 at multiple points on the surface of the pull rod 207. This ensures a more balanced locking force on the pull rod 207, preventing localized stress concentration caused by a single locking block 301 bearing all the locking pressure, and reducing wear between the locking blocks 301 and the locking plate 302. The three pneumatic vibrators 404 create multi-point coordinated vibration, resulting in a more even distribution of vibration force on the casting surface and a wider coverage area. This allows them to simultaneously act on the core sand in different areas of the casting, promoting rapid core sand breakage. The two support frames 5 are symmetrically distributed at the bottom of the workbench 1, which can evenly transfer the weight of the workbench 1 and the clamping and vibration components 4 above to the ground, avoiding the tilting or deformation of the workbench 1 caused by unilateral force. The guide groove 6 and guide slider 7 can provide precise guidance when installing the clamping plate 204. The limiting groove 8 can limit the range of motion of the connecting plate 206. The buckle 9 can be rotated to engage with the top of the moving plate 203, replacing the manual continuous pulling of the moving rod 303. The limiting rod 10 can provide precise limiting and guidance for the fixed plate 403.

[0029] The working principle of this utility model is as follows: When replacing the clamping plate 204, by pulling the buckle block 9, the buckle block 9 drives the locking plate 302 to move and compress the second spring 304 via the moving rod 303. When the locking plate 302 disengages from the locking block 301 and the buckle block 9 approaches the top of the moving plate 203, the buckle block 9 is rotated to engage with the moving plate 203. Then, the pull rod 207 is pulled, and the pull rod 207 drives the insert block 205 to move and compress the first spring 208 via the connecting plate 206. When the insert 205 disengages from the inner cavity of the clamping plate 204, the clamping plate 204 can be pulled out upwards for replacement. During operation, the motor 201 drives the moving plate 203 to move through the lead screw 202. The moving plate 203 drives the clamping plate 204 to move and clamp and fix the casting. The top cylinder 401 drives the push rod 402 to move the fixed plate 403 downwards. The fixed plate 403 drives the pneumatic vibrator 404 to fit against the casting. The pneumatic vibrator 404 starts to generate vibration and transmits it to the casting to achieve core removal.
