Description

Technical Field

[0001] This utility model relates to the field of die casting mold core technology, specifically to a die casting mold core repair platform. Background Technology

[0002] The die-casting core is the core functional component of the die-casting mold. It is a key component that comes into direct contact with the high-temperature molten metal and presses the molten metal into a casting of a specific shape through its internal cavity structure. It directly determines the final shape, dimensional accuracy, and surface quality of the die-cast product.

[0003] In existing die casting mold core repair operations, the mold core is mostly placed directly on the repair table. When repair personnel need to inspect or repair different parts of the mold core, such as the cavity depths and corner gaps, they need to manually push and flip the mold core to adjust its position and angle on the table. During the movement of the mold core, friction and collision will occur with the table, causing secondary damage such as cavity scratches and edge bumps, which in turn affects the accuracy and lifespan of the repaired mold core. Therefore, a die casting mold core repair platform is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that friction and collision between the mold core and the table surface during the movement of the mold core will cause secondary damage such as cavity scratches and edge bumps, which will affect the accuracy and life of the mold core after repair.

[0018] like Figures 1 to 5As shown, a die-casting mold core repair platform includes: a fixed frame 1, with at least one guide rod 101 on the outer side of the fixed frame 1; and a fixing assembly, disposed on the outer side of the fixed frame 1, for clamping the mold core. The fixing assembly includes a support member 2 and an adjusting member 3. The support member 2 is disposed on the outer side of the fixed frame 1 for controlling the position movement of the mold core, and the adjusting member 3 is disposed inside the support member 2 for adjusting the angle of the mold core. The support member 2, in conjunction with the adjusting member 3, adjusts the mold core in different directions. Specifically, when it is necessary to carry out repair work on the die-casting mold core, the operation process must strictly follow the following steps to ensure repair accuracy and mold core safety. First, the mold core to be repaired is placed stably on the preset bearing area on the top of the fixed frame 1 to ensure the initial positioning of the mold core and avoid displacement during initial placement. Then, the fixing assembly is activated, and the mold core is clamped and fixed by the synergistic action of the adjusting member 3 and the support member 2. The support member 2 first initially limits the horizontal position of the mold core through the connection structure with the fixed frame 1. Section 3 then applies stable pressure from the side and top of the mold core through its own clamping components, forming a multi-directional clamping effect to prevent the mold core from loosening or shifting during subsequent adjustments. Finally, according to maintenance needs, the horizontal separation of the mold core is achieved by moving the support 2 along the preset trajectory of the fixed frame 1. At the same time, the adjustment component 3 activates the angle adjustment function, causing the mold core to rotate or tilt around the preset axis, allowing maintenance personnel to clearly observe and access the deep cavity and corner gaps of the mold core, which were previously difficult to inspect. In addition, the external thread machined on the outside of the guide rod 101 can not only precisely mesh with the internal thread structure of the support 2, achieving smooth movement of the support 2 through thread transmission, but also rigidly constrain the movement direction of the support 2 during the movement, preventing the support 2 from shifting laterally or shaking, thereby ensuring that the mold core maintains a stable posture during the separation process and preventing the mold core from colliding or scratching due to unstable separation. The guide rod 101 can be manually or electrically controlled.

[0019] like Figures 1 to 5 As shown, a support platform 102 is also provided on the outside of the fixing frame 1. Specifically, during the initial placement of the mold core, the support platform 102 can bear the entire weight of the mold core, preventing the mold core from directly contacting other parts of the fixing frame 1 and causing wear. During the positioning stage before clamping and fixing, maintenance personnel can quickly adjust the placement position of the mold core according to the scale lines marked on the surface of the support platform 102 to ensure that the center of the mold core is aligned with the clamping center of the fixing component, thereby improving the accuracy of subsequent clamping. During maintenance, if it is necessary to pause the operation or change the maintenance tools, the support platform 102 can support the mold core again, providing a safe operating interval for maintenance personnel and preventing the mold core from slipping or colliding when it is not fixed. In addition, the support platform 102 and the fixing frame 1 adopt a detachable connection structure. When it is necessary to maintain mold cores of different sizes or weights, the appropriate support platform 102 can be quickly replaced, further improving the versatility of the platform.

[0020] like Figures 1 to 5 As shown, the support member 2 includes a fixed frame 201, and there are multiple fixed frames 201 distributed at both ends of the guide rod 101. A fixed ring 202 and a sliding block 203 are sequentially arranged inside the fixed frame 201. The fixed ring 202 is circular, and the sliding block 203 slides outside the fixed ring 202. Specifically, when adjusting the angle for mold core maintenance, the fixed ring 202 is precisely fixed to the mounting groove inside the fixed frame 201 by bolts, and the center of its circular trajectory coincides with the center of the mold core, ensuring coaxiality during mold core rotation. The inner side of the sliding block 203 has a groove that matches the outer side of the fixed ring 202. The groove is inlaid with a wear-resistant coating, which reduces the wear of the sliding block. The friction coefficient between the sliding block 203 and the fixed ring 202 further improves the service life of the components. When the mold core angle needs to be adjusted, the maintenance personnel push the sliding block 203 with external force, so that it slides along the circular trajectory of the fixed ring 202. The sliding block 203 then drives the mold core to rotate synchronously through the connection structure with the adjusting component 3, so as to realize the arbitrary angle adjustment of the mold core. At the same time, the fixed ring 202 adopts a T-shaped ring or dovetail ring design. Its special cross-sectional shape can form a locking structure with the sliding groove of the sliding block 203, preventing the sliding block 203 from axially falling off or shifting during the sliding process, ensuring the stability of the mold core position during the angle adjustment process, and avoiding the mold core collision caused by component loosening.

[0021] like Figures 1 to 5As shown, the adjusting component 3 includes a fixed plate 303. A limiting plate 306 and a connecting frame 301 are respectively provided on the outer side of the fixed plate 303. Multiple connecting frames 301 and limiting plates 306 are present. A rotating shaft 302 is provided on the outer side of the connecting frame 301, and the rotating shaft 302 rotates inside the sliding block 203. The limiting plates 306 are distributed at both ends of the fixed plate 303. A threaded rod 304 is threadedly connected inside the fixed plate 303. A pressure plate 305 is provided on the outer side of the threaded rod 304. Specifically, in actual maintenance operations, the mold core to be maintained is first placed on the top of the support platform 102. Based on the size of the mold core, the adjustment is then performed... Adjust the position of the limiting plate 306 through the mounting holes on the fixing plate 303 so that the two L-shaped limiting plates 306 are respectively in contact with the two side edges of the mold core, initially defining the horizontal position of the mold core. Next, rotate the threaded rod 304. Since the threaded rod 304 precisely engages with the threaded hole inside the fixing plate 303, the threaded rod 304 will move axially during rotation, thereby driving the outer pressure plate 305 closer to the top of the mold core until the pressure plate 305 is in close contact with the top of the mold core, cooperating with the limiting plate 306 to clamp it, ensuring that the mold core will not shift during subsequent operations. After the mold core is clamped, If the mold core needs to be separated, the fixed frame 201 is pushed by external force, and the fixed frame 201 will move along the external thread trajectory of the guide rod 101, causing the support member 2 and the adjusting member 3 connected to it, as well as the mold core, to move synchronously, thereby separating the mold core from other components. If the mold core angle needs to be adjusted, on the one hand, the sliding block 203 is pushed to slide along the fixed ring 202, causing the mold core to rotate around the annular trajectory; on the other hand, the rotating shaft 302 can rotate in the bearing inside the sliding block 203, causing the fixed plate 303 and the mold core to tilt around the axis of the rotating shaft 302, thereby achieving the angle of the mold core in the vertical plane. The angle adjustment, through the combination of these two adjustment methods, allows the mold core to be positioned in any posture required for maintenance, making it convenient for maintenance personnel to use tools to clean, inspect, or repair parts such as deep cavities and corner gaps, greatly improving the convenience of maintenance operations. In addition, the end of the threaded rod 304 is equipped with a non-slip handle, which makes it easy for maintenance personnel to apply rotational force. Furthermore, the threaded rod 304 and the pressure plate 305 are connected by a ball joint, which allows the pressure plate 305 to adaptively adjust its angle according to the surface shape of the top of the mold core, ensuring that the contact area between the pressure plate 305 and the mold core is maximized and avoiding excessive local pressure that could cause the mold core to deform.

[0022] like Figures 1 to 5As shown, the outer side of the sliding block 203 is also provided with multiple limit pins, which are respectively connected to the fixed ring 202 and the rotating shaft 302. Specifically, one end of the limit pin is provided with an external thread, which precisely matches the threaded hole on the outer side of the sliding block 203, the positioning hole on the fixed ring 202, and the threaded hole at the end of the rotating shaft 302. After the rotation angle of the mold core is adjusted by the cooperation of the sliding block 203 and the fixed ring 202, the limit pin is screwed into the connecting hole between the sliding block 203 and the fixed ring 202. The limit pin will simultaneously embed into the threaded hole of the sliding block 203 and the positioning hole of the fixed ring 202, forming a rigid... The connection restricts the sliding block 203 from sliding along the fixed ring 202. After the tilt angle of the mold core is adjusted by the cooperation of the rotating shaft 302 and the sliding block 203, another set of limit pins is screwed into the connection hole between the sliding block 203 and the rotating shaft 302. The limit pins will be embedded in the threaded hole of the sliding block 203 and the threaded hole of the rotating shaft 302, fixing the position of the rotating shaft 302 and preventing it from rotating during maintenance. This threaded connection limit method can ensure the stability of the mold core after the angle is adjusted, and it is also convenient for maintenance personnel to disassemble the limit pins at any time to readjust the angle as needed. The operation is flexible and highly reliable.

[0023] like Figures 1 to 5 As shown, the fixing plate 303 also has multiple mounting holes inside. A connecting rod is installed inside each mounting hole and connects to the limiting plate 306. Specifically, the multiple mounting holes inside the fixing plate 303 are evenly spaced in a straight line, and each mounting hole has an internal thread machined on its inner wall, precisely matching the external thread at the end of the connecting rod. When clamping mold cores of different sizes, maintenance personnel can screw the connecting rod into the corresponding mounting hole on the fixing plate 303 according to the width of the mold core, and then connect the connecting rod to the limiting plate 306 via the other end of the connecting rod. The connecting structure of plate 306 drives the limiting plate 306 to move along the length of the fixed plate 303 until the distance between the two limiting plates 306 matches the width of the mold core. This adjustable limiting plate 306 structure greatly improves the versatility of the platform. At the same time, the linear distribution of the mounting holes ensures the linearity of the moving trajectory of the limiting plate 306, preventing the limiting plate 306 from shifting during adjustment. This ensures the accuracy of the fitting between the limiting plate 306 and the edge of the mold core, providing a stable foundation for subsequent clamping and fixing.

[0024] like Figures 1 to 5As shown, the working state of this die-casting mold core repair platform is as follows: During mold core repair, the mold core is first placed on the top of the fixed frame 1. The guide rod 101 on its outer side is used to guide the movement direction of the support 2, and the support platform 102 provides initial placement and support for the mold core. During repair, the mold core is first placed on the support platform 102. The position of the L-shaped limiting plate 306 is adjusted to match the mold core size through the mounting hole of the fixed plate 303 in the adjusting component 3 and the connecting rod. Then, the threaded rod 304, which is threaded to the fixed plate 303, is rotated to drive the pressure plate 305 to cooperate with the limiting plate 306 to achieve mold core clamping and fixing. After clamping, the mold core is separated by multiple fixed frames 201 in the support 2 moving along the guide rod 101. At the same time, the fixing ring 202T inside the fixed frame 201 is used to achieve the same result. The sliding engagement of the U-shaped or dovetail shape with the sliding block 203, and the rotational engagement of the rotating shaft 302 of the connecting frame 301 in the adjusting component 3 within the sliding block 203, allows for multi-angle adjustment of the mold core. Furthermore, the limiting pin on the outer side of the sliding block 203 can be fixed in position after angle adjustment, thus preventing friction and collision between the mold core and the table surface throughout the process and ensuring the accuracy and lifespan of the mold core.

[0025] In summary, this utility model includes: a fixed frame 1, with at least one guide rod 101 on the outer side of the fixed frame 1; and a fixing assembly, disposed on the outer side of the fixed frame 1, for clamping the mold core. The fixing assembly includes a support member 2 and an adjusting member 3. The support member 2 is disposed on the outer side of the fixed frame 1 for controlling the position movement of the mold core, and the adjusting member 3 is disposed inside the support member 2 for adjusting the angle of the mold core. The support member 2, in conjunction with the adjusting member 3, adjusts the mold core in different directions. Through the arrangement of the fixed frame 1, support member 2, and adjusting member 3, this utility model achieves flexible adjustment of the mold core during maintenance by cooperating with the fixed frame 1, guide rod 101, fixed frame 201, fixed ring 202, sliding block 203, connecting frame 301, rotating shaft 302, fixing plate 303, pressure plate 305, and limiting plate 306.
