Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a multi-point mold processing positioning structure. Background Technology

[0002] In modern manufacturing, molds, as fundamental process equipment in industrial production, are hailed as the "mother of industry," and their quality directly determines the precision, quality, and production efficiency of products. Mold processing is a highly precise and complex process involving multiple procedures and steps. The positioning structure, as a key link in mold processing, plays a crucial role in ensuring the relative positional accuracy of the various components of the mold and guaranteeing the quality of the final molded product. A positioning structure for mold processing, disclosed in CN222857935U, includes a worktable and a positioning assembly. The positioning assembly includes a transverse clamping plate, a first electric push rod, a mounting base, a rotating plate, a longitudinal clamping plate, and a driving component. The transverse clamping plate is slidably connected to the worktable, the first electric push rod is connected to the transverse clamping plate, the mounting base is mounted on the first electric push rod, the longitudinal clamping plate is slidably connected to the transverse clamping plate, and the two ends of the rotating plate are rotatably connected to the mounting base and the longitudinal clamping plate, respectively. The driving component drives the two transverse clamping plates to move closer to each other, thereby clamping the two transverse clamping plates on the left and right sides of the workpiece. Then, the electric push rod is activated to drive the mounting base to move, causing the mounting base to move the rotating rod, which in turn moves the longitudinal clamping plate, causing the two longitudinal clamping plates on the transverse clamping plate to move closer to each other, thereby clamping the front and rear sides of the mold. The existing technology described above can only clamp the mold horizontally (left and right) and vertically (up and down). However, the fixed points overlap, making it inconvenient to clamp the mold at multiple points. The positioning effect of the mold is not good, making it difficult to effectively separate the forces on the mold during use. This makes the mold prone to stress concentration and damage. Furthermore, the use of a drive motor and multiple electric push rods to clamp the mold increases the actual use cost and the difficulty of later maintenance. Therefore, corresponding improvements are needed. Summary of the Invention

[0003] The purpose of this utility model is to provide a multi-point mold processing positioning structure to solve the problems mentioned in the background art, such as the inconvenience of clamping the mold at multiple points and the high cost of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-point mold processing positioning structure, including a fixed platform, a support base, and a driving cavity, wherein the support base is fixed at the center position of the outer side of the fixed platform, and the driving cavity is provided at the bottom end of the fixed platform; The drive cavity is equipped with a clamping drive mechanism. I-shaped guide strips are fixed on both sides of the bottom of the fixed platform, and sliders are slidably connected to the bottom of the I-shaped guide strips. Guide plates are connected to the bottom of the sliders, and fixed seats are fixed on both sides of the top of the guide plates. Loading and unloading components are provided inside the fixed seats, and connecting plates are connected to the top of the loading and unloading components. Clamping frames are connected to the top of the connecting plates, and rubber plates are fixed on both sides inside the clamping frames.

[0005] Furthermore, the clamping drive mechanism includes a drive motor, which is located inside the drive cavity. The output shaft of the drive motor is fixed with a drive shaft, and the bottom end of the drive shaft is fixed with two swing arms via a fixed plate. A connecting column is fixed on one side of the bottom end of each swing arm, and a pull rod is movably sleeved on the outside of each connecting column. The other end of each pull rod is movably connected with a movable column, and the movable column is fixed to the top of the guide plate.

[0006] Furthermore, the movable column is located at the center of the bottom end of the guide plate, and the guide plate is slidably connected to the fixed platform through a slider and an I-shaped guide strip.

[0007] Furthermore, the clamping frame has an L-shaped cross-section, the top of the connecting plate is provided with a threaded hole, the top of the clamping frame is connected with a fixing bolt, and one end of the fixing bolt extends into the threaded hole on the connecting plate.

[0008] Furthermore, the loading and unloading assembly includes a fixing groove disposed inside the fixing seat, and a locking block is disposed on one side inside the fixing groove, and a guide post passes through the locking block. A reset spring is connected to one side of the locking block, and one end of the reset spring is connected to the inner wall of the fixing groove.

[0009] Furthermore, a plug is fixed to the bottom of the connecting plate, and one end of the plug extends into the fixing groove. A locking hole is provided on one side of the plug, and one end of the locking block extends into the locking hole.

[0010] Furthermore, the fixing groove is stepped, and the bottom end of the locking hole is connected to the fixing groove.

[0011] Furthermore, the card block is provided with a locking hole, and a locking bolt is provided on the outside of the card block, with the locking bolt passing through the fixing seat and extending into the locking hole on the card block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the multi-point mold processing positioning structure can clamp the mold at multiple points to ensure the firmness of the clamping, and the clamping parts can be replaced to further adapt to the clamping of molds of different specifications. The swing arm can be rotated to drive the two pull rods to rotate synchronously, which in turn pulls the two guide plates closer to each other. At the same time, the slider slides on the I-shaped guide bar, which drives the fixed seat to move synchronously, so that the corresponding clamping frame can move synchronously until the clamping frame is locked onto the corresponding mold. There are four clamping frames, corresponding to the four corners of the mold, to achieve multi-point fixation of the mold, ensure the firmness of the mold positioning, and distribute the pressure on the mold to multiple support fixing points, reducing the risk of stress concentration. In addition, the rubber plate on the clamping frame can also play a role in mold protection. Pull the locking block to move it along the guide post, causing the return spring to be stretched until the locking block disengages from the locking hole, allowing the connecting plate to disengage from the fixing groove for replacement. Then, tighten the fixing bolts to disengage them from the threaded holes on the connecting plate, allowing the clamping frame to be disengaged from the connecting plate for further disassembly. Later, the clamping frame and rubber plate can be replaced according to the specifications and shape of the mold to meet the clamping requirements of different molds. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0018] To address the issue of poor mold-fixing performance in existing mold-processing and positioning structures, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 3 , Figure 4 A multi-point mold processing positioning structure includes a fixed platform 1, a support base 10, and a drive cavity 101. The support base 10 is fixed at the center of the outer side of the fixed platform 1. The drive cavity 101 is provided at the bottom end of the fixed platform 1. A clamping drive mechanism 2 is provided inside the drive cavity 101. The clamping drive mechanism 2 includes a drive motor 201, which is located inside the drive cavity 101. A drive shaft 202 is fixed to the output shaft end of the drive motor 201. Two swing arms 203 are fixed to the bottom end of the drive shaft 202 through a fixed plate. A connecting rod is fixed to one side of the bottom end of each swing arm 203. The column 204 is connected to the outer side of the column 204 with a pull rod 205. The other end of the pull rod 205 is connected to a movable column 206. The movable column 206 is fixed to the top of the guide plate 3. The movable column 206 is located at the center of the bottom end of the guide plate 3. The guide plate 3 is slidably connected to the fixed platform 1 through the slider 301 and the I-shaped guide strip 102. The fixed platform 1 has I-shaped guide strips 102 fixed on both sides of the bottom end. The bottom end of the I-shaped guide strip 102 is slidably connected to the slider 301. The bottom end of the slider 301 is connected to the guide plate 3. In this embodiment, the mold is placed on the fixed platform 1, and then the drive motor 201 is driven to rotate the drive shaft 202 and the swing arm 203. During the rotation of the swing arm 203, the connecting column 204 rotates synchronously, which in turn pulls the pull rod 205 to rotate synchronously. This further pulls the two guide plates 3 closer to each other and makes the slider 301 slide along the I-shaped guide strip 102, which limits and guides the movement of the guide plate 3. This drives the fixed seat 4 and the clamping frame 5 to move synchronously until the clamping frame 5 is stuck at the corner of the mold. Together with the rubber plate 6, the four corners of the mold are clamped and limited to improve the stability of the mold processing. Example 2

[0019] This embodiment differs from Embodiment 1 in that it utilizes a loading and unloading assembly to allow for the disassembly and replacement of the positioning components, thus meeting the positioning needs of molds of different specifications. Therefore, the following technical solution is disclosed; please refer to the details. Figure 1 , Figure 2 , Figure 5 The guide plate 3 has fixed seats 4 on both sides of the top. The fixed seats 4 are equipped with loading and unloading components. The top of the loading and unloading components is connected to the connecting plate 7. The bottom of the connecting plate 7 is fixed with a plug 701. One end of the plug 701 extends into the fixed groove 401. A locking hole 702 is provided on one side of the plug 701. One end of the locking block 8 extends into the locking hole 702. The loading and unloading components include a fixed groove 401 provided inside the fixed seat 4. A locking block 8 is provided on one side of the fixed groove 401. A guide post 801 passes through the inside of the locking block 8. A return spring 9 is connected to one side of the locking block 8. One end of the return spring 9 is connected to the inner wall of the fixed groove 401. The fixed groove 401 is stepped. The bottom of the locking hole 702 is connected to the fixed groove 401. A locking hole is provided on the locking block 8. A locking bolt is provided on the outside of the locking block 8. The locking bolt passes through the fixed seat 4 and extends into the locking hole on the locking block 8. In use, pull the locking block 8 to make it move horizontally along the guide post 801, so that the return spring 9 is stretched. Then, insert the plug 701 into the fixing groove 401. Then release the locking block 8. Under the elastic force of the return spring 9, the locking block 8 can be driven to return to its original position until the locking block 8 is inserted into the locking hole 702, thereby fixing and limiting the connection plate 7 and completing the fixed installation of the connection plate 7. The locking bolt and the locking hole on the locking block 8 can be used to lock the position of the locking block 8, improving the firmness of the insertion of the locking block 8. The connection plate 7 can be disassembled by reversing the operation later. The top of the connecting plate 7 is connected to a clamping frame 5, and the two sides inside the clamping frame 5 are fixed with rubber plates 6. The clamping frame 5 has an L-shaped cross section. The top of the connecting plate 7 is provided with a threaded hole. The top of the clamping frame 5 is connected to a fixing bolt 501, and one end of the fixing bolt 501 extends into the threaded hole on the connecting plate 7. In this embodiment, the clamping frame 5 is attached to the connecting plate 7, and then the fixing bolt 501 is screwed through the clamping frame 5 and screwed into the threaded hole on the connecting plate 7 to fix the clamping frame 5. The clamping frame 5 can be disassembled and replaced by performing the reverse operation later.
