Description

Technical Field

[0001] This utility model relates to the field of mold clamping technology, and in particular to a mold processing fixture. Background Technology

[0002] During mold processing, fixtures are typically used to secure the mold in order to ensure machining accuracy and stability. As an important tooling device, fixtures play a role in positioning and clamping during milling, drilling, grinding, and other machining processes, thereby preventing the mold from shifting under stress. As the complexity of mold processing increases, the structure and ease of operation of fixtures become important factors affecting machining efficiency and quality.

[0003] A Chinese patent has been published: a fixture for mold processing, patent announcement number: CN207858343U. This patent "includes a rotating handle, a rotating block, a fixed block, a spiral rod, a moving block, a platform, a groove, a positioning block, an inner slide rail, a base, a track, an mounting block, and a shock-absorbing slip ring. The fixed block is threadedly connected to the spiral rod, and the bottom surface of the fixed block is welded to the upper surface of the platform. The spiral rod is embedded in the left end face of the rotating block, and the left side of the spiral rod is in contact with the right end face of the moving block. A positioning block is provided on the left side of the groove, and the positioning block and the platform are an integrated structure. This utility model is a fixture for mold processing, which is structurally equipped with a shock-absorbing slip ring embedded in the interior of the mounting block."

[0004] While this fixture can absorb most of the vibrations generated during processing through the rubber and damping layers, effectively reducing vibration and ensuring fixture stability, it still has certain shortcomings in use. For example, when clamping or releasing the mold, the operator needs to frequently rotate the threaded rod to complete the clamping action, which is cumbersome, time-consuming, and labor-intensive, reducing processing efficiency. Furthermore, this type of fixture can usually only fix some surfaces during processing, failing to simultaneously and stably clamp all four surfaces of the mold, resulting in low fixation strength. This makes the mold prone to displacement during processing, affecting hole accuracy and processing quality. Therefore, the structure of the existing mold processing fixture still needs further improvement to achieve both easy operation and stable clamping. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a mold processing fixture to solve the problem that when clamping or releasing a mold, the operator needs to frequently rotate the threaded rod to complete the clamping action, which is cumbersome, time-consuming and labor-intensive, and reduces processing efficiency.

[0006] To achieve the above objectives, this utility model provides a mold processing fixture, including a worktable, a support plate on the top of the worktable, a sliding rod passing through the middle part of the support plate, a placement plate fixedly connected to the top of the sliding rod, a clamping mechanism on the top of the worktable for clamping the mold placed on the top of the placement plate, and a cleaning mechanism on the top of the worktable for cleaning the debris generated after drilling holes in the mold on the top of the placement plate.

[0007] Preferably, the clamping mechanism includes a connecting rod fixedly connected to the bottom of the sliding rod, a gathering cover fixedly connected to the bottom of the connecting rod, the gathering cover being pyramid-shaped, a spring sleeved on the outer wall of the sliding rod, the top and bottom of the spring being fixedly connected to the bottom of the support plate and the top of the connecting rod, respectively, four sets of limiting plates fixedly connected to the top of the inner wall of the worktable, a linkage rod slidably connected between the inner walls of the four sets of limiting plates, a roller rotatably connected to the end of the linkage rod near the gathering cover, a first through groove opened at the top of the linkage rod, a guide post fixedly connected between the inner walls of the first through groove, a second through groove opened on each of the four surfaces of the top of the worktable surrounding the support plate, a linkage plate rotatably connected to the bottom of each of the four second through grooves, the end of the linkage plate near the linkage rod being in the first through groove, a sliding groove opened on the side wall of one end of the linkage plate, and the guide post slidably connected in the sliding groove.

[0008] Preferably, an inclined adjustment frame is fixedly connected to the top of the linkage plate. The adjustment frame has a Z-shaped structure, and a threaded rod is placed inside the adjustment frame. A clamping plate is fixedly connected to the bottom end of the threaded rod.

[0009] Preferably, the cleaning mechanism includes a fan fixedly connected to the top of the workbench, the output end of the fan being located in the middle of the support plate, and the top of the workbench having cleaning grooves on all four sides near the support plate for debris to fall into the collection hood. A baffle is fixedly connected to the top of the workbench near the outer wall of the support plate, and the bottom of the collection hood is connected to a discharge pipe for guiding materials.

[0010] Preferably, the bottom of the inner wall of the workbench is provided with a storage box for storing debris generated during mold drilling.

[0011] Preferably, the linkage plate has a "V" shaped structure. When the gathering cover moves downward, it squeezes the roller and pushes the linkage rod to move. The movement of the linkage rod slides in the groove through the guide post and drives the linkage plate to rotate. The rotation of the linkage plate will drive the clamping support plate installed at the top of the linkage plate to rotate in the direction.

[0012] Preferably, a gathering plate for collecting falling debris is fixedly connected to the top of the inner wall of the workbench near the bottom of the support plate.

[0013] Preferably, the outer wall of the threaded rod is fitted with two opposing adjusting plates, which are located on both sides of the adjusting frame. The outer wall of the threaded rod is threaded with two fastening nuts, which are located on the side walls of the two adjusting plates respectively.

[0014] Preferably, when a mold is placed on top of the placement plate, the placement plate will drive the sliding rod and the gathering cover fixedly connected to the bottom to move downwards, and the movement of the gathering cover will drive the discharge end of the unloading pipe into the interior of the storage box.

[0015] Preferably, the clamp is L-shaped.

[0016] The beneficial effects of this utility model are: 1. This mold processing fixture, through its clamping mechanism, utilizes the linkage structure between a sliding rod, a gathering cover, a linkage rod, a linkage plate, and a clamping plate to achieve automatic clamping and fixation of the mold. When the mold is placed on the placement plate, its own weight causes the sliding rod to move downwards, thereby driving the gathering cover to press down. This further drives the rollers, linkage rod, and linkage plate to move synchronously, causing the clamping plate mounted on the top of the linkage plate to automatically move towards all four sides of the mold, achieving simultaneous clamping from multiple sides. This structure effectively avoids the tedious steps of operators frequently rotating the threaded rod, significantly reducing labor intensity and improving clamping efficiency. The "L"-shaped design of the clamping plate simultaneously provides limiting support for the sides and top surface of the mold, preventing displacement during processing and improving processing accuracy and stability.

[0017] 2. This mold processing fixture, through its cleaning mechanism, utilizes the synergistic effect of a fan, cleaning trough, collection hood, baffle, unloading pipe, and storage box to automatically remove processing debris after mold drilling. During operation, the fan blows air directly onto the mold surface, blowing residual debris into the cleaning trough. The debris then falls into the collection hood under gravity and is guided into the storage box through the unloading pipe, achieving centralized collection and storage of debris. The baffle effectively prevents debris from splashing, keeping the work area clean. This design not only reduces the frequency of manual cleaning but also avoids equipment wear and contamination problems caused by debris accumulation on the processing table surface, thereby improving the cleanliness of the mold processing environment and extending the equipment's lifespan.

[0023] like Figures 1 to 6As shown, a mold processing fixture includes a worktable 1, a support plate 2 on the top of the worktable 1, a sliding rod 3 passing through the middle part of the support plate 2, a placement plate 4 fixedly connected to the top of the sliding rod 3, a clamping mechanism on the top of the worktable 1 for clamping the mold placed on the top of the placement plate 4, and a cleaning mechanism on the top of the worktable 1 for cleaning the debris generated after drilling the mold on the top of the placement plate 4.

[0024] Further, see attached document. Figures 1 to 6 As shown, the clamping mechanism includes a connecting rod 5 fixedly connected to the bottom of the sliding rod 3. A gathering cover 6 is fixedly connected to the bottom of the connecting rod 5. The gathering cover 6 is pyramid-shaped. A spring 7 is sleeved on the outer wall of the sliding rod 3. The top and bottom of the spring 7 are fixedly connected to the bottom of the support plate 2 and the top of the connecting rod 5, respectively. Four sets of limiting plates 8 are fixedly connected to the top of the inner wall of the worktable 1. A linkage rod 9 is slidably connected between the inner walls of the four sets of limiting plates 8. A roller 10 is rotatably connected to the end of the linkage rod 9 near the gathering cover 6. A first through groove 11 is opened on the top of the linkage rod 9. A guide post 12 is fixedly connected between the inner walls of the first through groove 11. A second through groove 13 is opened on each of the four surfaces of the support plate 2 around the top of the worktable 1. The bottom of the four second through grooves 13... Each part is rotatably connected to a linkage plate 14. The end of the linkage plate 14 near the linkage rod 9 is located in the first through groove 11. A sliding groove 15 is opened on the side wall of one end of the linkage plate 14. The guide column 12 is slidably connected in the sliding groove 15. An inclined adjustment frame 16 is fixedly connected to the top of the linkage plate 14. The adjustment frame 16 is shaped like a "Z". A threaded rod 17 is placed inside the adjustment frame 16. A clamping plate 18 is fixedly connected to the bottom end of the threaded rod 17. The clamping plate 18 is shaped like an "L". Two opposing adjustment pieces 19 are sleeved on the outer wall of the threaded rod 17. The two adjustment pieces 19 are located on both sides of the adjustment frame 16. Two fastening nuts 20 are threadedly connected to the outer wall of the threaded rod 17. The two fastening nuts 20 are located on the side walls of the two adjustment pieces 19 respectively. When the mold is clamped and fixed, the operator places the square mold to be processed on the top of the placement plate 4. The weight of the mold will cause the placement plate 4 and the sliding rod 3 to move downward. During the downward movement, the sliding rod 3 will stretch the spring 7, which will generate an upward elastic restoring force. At the same time, it will drive the gathering cover 6 at the bottom of the sliding rod 3 to move downward. When the gathering cover 6 moves downward, it will contact the rollers 10 on the four sides and generate a squeezing effect. After the rollers 10 rotate, they will drive the linkage rod 9 to slide outward. Due to the movement of the linkage rod 9 through the sliding linkage of the guide column 12 in the slide groove 15, the linkage plate 14 will rotate. At the same time, the rotation of the linkage plate 14 will drive the adjustment frame 16 installed at its top to rotate synchronously, thereby driving the threaded rod 17 and the clamping plate 18 to move closer to the support plate 2. The automatic clamping of the mold on all four sides is achieved through the "L"-shaped structure design of the clamping plate 18, which can simultaneously abut against the side wall and the top surface of the mold to form a multi-face clamping effect. This structure can effectively prevent the mold from shifting during drilling or milling, improve the stability of processing and the accuracy of hole positions, and eliminate the need for frequent manual rotation of the threaded rod 17. The operation is convenient and the clamping is firm.

[0025] Further, see attached document. Figures 1 to 4 As shown, the cleaning mechanism includes a fan 21 fixedly connected to the top of the workbench 1. The output end of the fan 21 is located in the middle of the support plate 2. The top of the workbench 1 is provided with cleaning grooves 22 on the four sides near the support plate 2 for debris to fall into the collection hood 6. A baffle 23 is fixedly connected to the top of the workbench 1 near the outer wall of the support plate 2. The bottom of the collection hood 6 is connected to a discharge pipe 24 for guiding materials. After the mold processing is completed, the cleaning mechanism starts to work. By starting the fan 21 fixed on the top of the workbench 1, the fan 21 blows airflow onto the mold surface on the top of the placement plate 4. The airflow blows the debris generated after drilling away from the mold surface. The debris slides down the cleaning groove 22 into the inside of the collection hood 6 under the push of the airflow. The baffle 23 plays a guiding and protective role in this process to prevent the debris from splashing into the external environment. The unloading pipe 24 connected to the bottom of the collection hood 6 can guide the collected debris into the storage box 25 to achieve automatic collection and centralized storage. Since the collection hood 6 has a pyramid-shaped structure, it can effectively guide the debris to converge downwards and reduce residue. Meanwhile, the storage box 25 is used to collect the debris in a unified manner, which facilitates subsequent cleaning and recycling and prevents the debris from scattering and contaminating the workbench 1; By cooperating with the blower 21, cleaning tank 22, collection hood 6, and unloading pipe 24, rapid chip removal can be achieved after mold processing, keeping the worktable 1 clean, ensuring a clean environment for the next processing, improving processing continuity, and extending equipment lifespan. Further, see attached document. Figure 1 As shown, a storage box 25 for storing debris generated during mold drilling is placed at the bottom of the inner wall of the workbench 1. It serves to collect the debris generated during the drilling process of the mold. This structure can effectively prevent the debris from falling outside the workbench 1 during the processing, thus avoiding affecting the cleanliness of the operating environment.

[0026] Further, see attached document. Figure 3 and Figure 4 As shown, the linkage plate 14 has a "V" shaped structure. When the gathering cover 6 moves downward, it will squeeze the roller 10 and push the linkage rod 9 to move. The movement of the linkage rod 9 will slide in the slide groove 15 through the guide column 12 and drive the linkage plate 14 to rotate. The rotation of the linkage plate 14 will drive the clamp plate 18 installed at the top of the linkage plate 14 to rotate in the direction of the support plate 2. When driven by the downward movement of the gathering cover 6 and the pressing roller 10, the rotation process is smoother. This structure distributes force evenly during movement, effectively reducing frictional resistance between mechanisms and improving the sensitivity and stability of the linkage transmission. When the gathering cover 6 moves downward, the linkage plate 14 responds quickly, driving the top clamping plate 18 to rotate synchronously towards the support plate 2, ensuring uniform clamping of the mold in four directions. This design improves the coordination of clamping actions and the firmness of mold fixation, avoiding the offset problems caused by traditional single-sided or double-sided clamping, thus significantly improving the accuracy and safety of mold processing.

[0027] Further, see attached document. Figure 3 As shown, a gathering plate 26 for collecting falling debris is fixedly connected to the top of the inner wall of the workbench 1 near the bottom of the support plate 2. It can guide the falling debris and gather it before it falls into the storage tank 25. This structure can effectively prevent the debris from scattering due to rebound or airflow interference during the falling process, and ensure that the debris is smoothly guided into the interior of the gathering hood 6 and the discharge pipe 24 along the predetermined path.

[0028] Further, see attached document. Figure 1 and 3 As shown, when a mold is placed on top of the placement plate 4, the placement plate 4 will drive the sliding rod 3 and the gathering cover 6 fixedly connected to the bottom to move downward. The movement of the gathering cover 6 will drive the discharge end of the unloading pipe 24 into the interior of the storage box 25, thus preventing the debris from falling out of the interior of the storage box 25.
