Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and in particular to an automated grinding device for mold surface treatment. Background Technology

[0002] Grinding the surface of molds is a crucial process to ensure their precision and performance. Currently, mold surface grinding operations require adjustments to the clamping structure for different mold specifications to achieve precise positioning. Furthermore, frequent switching between the mold to be ground and the already ground mold is necessary to ensure operational continuity.

[0003] To accommodate molds of various sizes, traditional grinding equipment requires multiple sets of clamping power components, which not only increases the cost of equipment manufacturing and maintenance, but also requires manual assistance to adjust the clamping state. The degree of automation needs to be improved, and it is difficult to efficiently balance mold positioning accuracy, equipment adaptability and operation continuity. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an automated grinding device for mold surface treatment, which solves the problems of high cost of clamping components and low degree of automation when traditional mold grinding equipment is adapted to multiple mold specifications.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows: An automated grinding device for mold surface treatment includes a frame, a gantry frame located at the center of the top surface of the frame, the gantry frame spanning the frame along its width, and a linear drive module mounted on the gantry frame. The moving end of the linear drive module is equipped with a grinding component. At least two platforms are mounted on the frame along its length, each platform being slidably connected to the frame and capable of sliding along the length of the frame. A synchronous connection structure is provided between the platforms to achieve synchronous movement. A platform drive component is provided on the frame for driving the platforms to move, and an alignment and limiting component is provided on the top surface of the platforms for limiting the mold.

[0006] Optionally, two slide rails are symmetrically fixed on the top surface of the frame, and a slider is fixed on the bottom surface of the platform. The slide rails extend along the length of the frame, and the slider is set corresponding to the slide rails and slidably installed on the outside of the slide rails. The synchronous connection structure includes a connecting strip, with both ends of the connecting strip fixedly connected to each platform. The platform driving component is a second cylinder, which is fixed in the middle of one side of the top surface of the frame, and its extended end is fixed to any platform to drive all platforms to move synchronously.

[0007] Optionally, the alignment and limiting assembly includes a first slide groove opened in the middle of the top surface of the platform. The first slide groove extends along the length of the frame. Two auxiliary alignment blocks are symmetrically slidably arranged in the first slide groove. A bidirectional screw is rotatably connected to the inner wall of the first slide groove through a bearing. The two auxiliary alignment blocks are respectively threaded to both ends of the bidirectional screw through threaded holes. One end of the bidirectional screw passes through the platform and is fixed with a first knob.

[0008] Optionally, the alignment and limiting assembly further includes two second sliding grooves symmetrically opened on the top surface of the platform. The two second sliding grooves are respectively located on both sides of the first sliding groove and extend perpendicularly to the first sliding groove. The second sliding grooves pass through the platform. A driving block is slidably arranged in the second sliding groove. The upper and lower parts of the driving block are provided with protrusions. The protrusions respectively engage with the top and bottom surfaces of the platform to prevent the driving block from slipping. A second screw is threadedly connected to the upper end of the driving block. The axis of the second screw is perpendicular to the bidirectional screw. A second knob is fixed at one end of the second screw, and the other end is rotatably connected to the main alignment block through a bearing. The main alignment block is slidably connected to the top surface of the platform.

[0009] Optionally, the top surface of the frame is symmetrically fixed with two drive frames extending along their length direction. The bottom of the drive block is fixed with a driven column, which is inserted into the drive frame and can slide along the drive frame so that the drive block can slide along the second slide groove by moving the platform. The middle part of the drive frame extends in a straight line, and its two ends extend in an inclined section away from the opposite drive frame.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This invention, by setting a first slide groove with a bidirectional screw and an auxiliary alignment block, a second slide groove with a second screw and a main alignment block, and a second cylinder and connecting bar to drive the platform to move synchronously, can not only adjust the spacing of the alignment blocks by rotating the knob to adapt to molds of various specifications, but also realize the alternating entry of the two platforms into the grinding area, eliminating the need for multiple sets of clamping power components, reducing equipment manufacturing and maintenance costs, and improving the degree of automation.

[0011] This invention features a drive frame with inclined and straight sections, and a driven column fixed to the drive block. By moving the platform along the length of the frame, the driven column slides within different sections of the drive frame, automatically completing the clamping and unclamping actions of the mold in conjunction with the main alignment block. This eliminates the need for manual operation or additional power equipment to drive the clamping structure, further simplifying the operation process and reducing manpower input.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 6 This embodiment provides an automated grinding device for mold surface treatment, including a frame 1. A gantry frame is fixed in the middle of the top surface of the frame 1. The gantry frame spans the frame 1 in the width direction. A linear drive module is fixed on the top surface of the gantry frame. A first cylinder arranged longitudinally is fixed at the moving end of the linear drive module. The extended end of the first cylinder is vertically downward and fixed with a grinding machine 18. The operation of the linear drive module can drive the grinding machine 18 to move in the width direction of the frame 1. The extension or retraction of the first cylinder can make the grinding head of the grinding machine 18 adapt to the height of the mold.

[0021] On the top surface of the frame 1, two slide rails 2 are symmetrically fixed with the centerline along the length of the frame 1 as the axis. On the top surface of the frame 1, two platforms 3 are arranged side by side along its length. On the bottom surface of the platform, two sliders 4 are fixed to each slide rail 2. The sliders 4 are slidably installed on the outside of the corresponding slide rail 2, so that the platform 3 can be slidably installed on the frame 1. That is, the platform 3 can slide along the length of the frame 1 on the top surface of the frame 1. The two platforms 3 are connected by two connecting strips 5. The two ends of the connecting strips 5 are fixed to the two platforms 3 respectively, so that the two platforms 3 can move synchronously.

[0022] A second cylinder 6 is fixed in the middle of one side of the top surface of the frame 1. The extended end of the second cylinder 6 is fixed to one of the platforms 3. By driving the second cylinder 6 to extend or retract, the effect of moving the two platforms 3 at the same time can be achieved.

[0023] A first slide groove 7 is provided in the middle of the top surface of the platform 3. The first slide groove 7 extends along the length of the frame 1. Two auxiliary alignment blocks 8 are symmetrically slidably installed on the inner wall of the first slide groove 7. The upper part of the auxiliary alignment blocks 8 protrudes from the top surface of the platform 3. A bidirectional screw 9 is rotatably connected to the inner wall of the first slide groove 7 through a bearing. One end of the bidirectional screw 9 passes through the platform 3 and is fixed with a first knob 10. The two auxiliary alignment blocks 8 are respectively threaded to the two ends of the bidirectional screw 9 through threaded holes. By rotating the first knob 10, the bidirectional screw 9 is driven to rotate, and the distance between the two auxiliary alignment blocks 8 is adjusted to ensure that the fixture is adapted to the width of the mold and to limit the mold width. Before grinding, the mold is inserted between the two adjusted auxiliary alignment blocks 8 to complete the initial alignment.

[0024] Two second sliding grooves 11 are symmetrically provided in the middle of the top surface of the platform 3. The two second sliding grooves 11 are located on both sides of the first sliding groove 7. The extension direction of the second sliding grooves 11 is perpendicular to the extension direction of the first sliding groove 7, and the second sliding grooves 11 penetrate the platform 3 from top to bottom. A driving block 12 is slidably installed in the second sliding groove 11. The upper and lower parts of the driving block 12 are symmetrically formed with protrusions 1201. The upper and lower protrusions 1201 respectively engage with the top and bottom surfaces of the platform 3, confining the driving block 12 in the second sliding groove 11 to prevent it from slipping out.

[0025] The upper end of the drive block 12 is threadedly connected to a second screw 13 through a threaded hole. The axis of the second screw 13 is perpendicular to the axis of the bidirectional screw 9. A second knob 14 is fixed to the end of the second screw 13 away from the bidirectional screw 9. A main alignment block 15 is rotatably mounted on the end of the second screw 13 near the bidirectional screw 9 through a bearing. The bottom surface of the main alignment block 15 is slidably connected to the top surface of the frame 1. Two drive frames 16 are symmetrically fixed to the top surface of the frame 1. The drive frames 16 extend along the length of the frame 1. The middle part of the drive frames 16 extends in a straight line, while both ends of the drive frames 16 are inclined and extend away from the side of the opposite drive frame 16. A driven post 17 is fixed to the bottom of the drive block 12 and is inserted into the drive frame 16.

[0026] When one of the platforms 3 is located directly below the gantry, the driven column 17 is in the middle of the drive frame 16. At this time, under the action of the driven column 17, the two main alignment blocks 15 clamp the two sides of the mold in the length direction and limit it in the length direction. The other platform 3 is on one side of the gantry, and the driven column 17 is located in the inclined section at the end of the drive frame 16. At this time, the two column alignment blocks separate, release the clamping of the mold, and then the mold can be removed.

[0027] By continuously extending and retracting the second cylinder 6, the two carriers 3 alternately enter the lower part of the gantry, thereby alternately performing the grinding work of the mold. During the grinding process, the second cylinder 6 continuously drives the carriers 3 to move according to the change of the grinding position, so as to cooperate with the movement of the linear drive module and ensure that the grinding work of multiple positions on the top surface of the mold is completed.

[0028] Furthermore, after the mold size changes, the first knob 10 is rotated to make the bidirectional screw 9 rotate, adjusting the distance between the two auxiliary alignment blocks 8 to match the mold width. The second knobs 14 on both sides are rotated to make the second screw 13 rotate, adjusting the distance between the two main alignment blocks 15 to match the mold length. This improves the adaptability of the entire grinding device, enabling it to grind molds of various sizes and specifications.

[0029] By setting up two alternating and continuously moving platforms 3, the grinding work can be carried out continuously. Relying on the force of the moving platform 3, the clamping and unclamping of the mold can be completed without manual clamping, which improves the automation level of the equipment, saves manpower, reduces the investment in power equipment for clamping, and lowers the manufacturing and operation and maintenance costs of the equipment.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
