Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a replaceable core structure for locomotive foot pad molds. Background Technology

[0002] The replaceable core structure of a locomotive floor mat mold is a mold structure used to manufacture locomotive floor mats. Its key feature is the ability to easily replace the core to accommodate different models or styles of locomotive floor mats. It typically consists of multiple components, including a molding core, positioning components, and fixing components. The molding core is the part that directly contacts the floor mat material and forms its shape; it is designed according to the different shapes and sizes of locomotive floor mats. The positioning components accurately determine the position of the core within the mold, ensuring precise fit with other mold components. The fixing components securely install the core in the mold, preventing displacement during injection molding.

[0003] When producing different styles or sizes of motorcycle floor mats, there's no need to remanufacture the entire mold. Simply replacing the corresponding core allows for rapid production switching, significantly reducing changeover time and improving efficiency. For example, when switching from producing one model to another, simply remove the original core, install the corresponding one, and production can continue, avoiding prolonged downtime caused by remanufacturing the mold. This also reduces the number and cost of molds. For small-batch, multi-variety motorcycle floor mat production, traditional mold manufacturing methods require a complete mold for each style, resulting in high costs. However, with a replaceable core mold structure, only a single mold body needs to be manufactured, and then the corresponding cores are produced according to different product requirements, thus reducing mold manufacturing costs.

[0004] When producing locomotive floor mats of different styles or sizes, the core cannot be directly replaced. The entire mold must be remanufactured or extensively modified, requiring significant time in design, processing, and debugging, leading to production halts and hindering rapid response to market demands. If the mold core is damaged, the lack of a replaceable core means the entire mold must be repaired, a complex and time-consuming process that causes prolonged production line downtime, impacting production progress. Therefore, a replaceable core structure for locomotive floor mat molds is proposed to address these issues. Utility Model Content

A fixing plate is fixedly connected to the top of both connecting plates. A demolding component is fixedly connected to the top of the square box.

[0008] As a further description of the above technical solution:

[0009] The demolding assembly includes a square box II, the bottom of which is fixedly connected to the top of the square box I. Multiple support columns I are fixedly connected inside the square box II. A fixing plate III is fixedly connected to the top of each support column I. A motor is fixedly connected to the rear side of the fixing plate III. A ring is fixedly connected to the drive end of the motor. A hollow column is fixedly connected inside the fixing plate III. A connecting rod II is slidably connected inside the hollow column. A roller is rotatably connected inside the connecting rod II. A support plate is fixedly connected to the left side of the top of the fixing plate III. A spring is fixedly connected to the top of the hollow column. A disc is fixedly connected to the drive end of the connecting rod II. A mold core is slidably connected to the top of the square box I.

[0010] As a further description of the above technical solution:

[0011] The top of each base plate is fixedly connected to a second support column, the top of each second support column is fixedly connected to a mounting plate, the top of the mounting plate is fixedly connected to a hydraulic cylinder, and the drive end of the hydraulic cylinder is fixedly connected to an upper mold.

[0012] As a further description of the above technical solution:

[0013] The inner walls of both sliders are slidably connected to the outer sides of the two fixed rods, and the bottom end of the fixed block is slidably connected to the inside of the square box.

[0014] As a further description of the above technical solution:

[0015] The bottom ends of the two sliders are slidably connected to the top of the square box one, and the outer sides of the two fixing plates two are slidably connected to the inner wall of the square box one.

[0016] As a further description of the above technical solution:

[0017] The bottom end of the ring is rotatably connected to the inside of the square box 2, and the outer side of the disc is slidably connected to the inside of the mold core;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cylinder pushes the fixing block two to fix the mold core, achieving a replaceable effect. The replaceable core structure ensures the precision and surface quality of the core, thereby improving the molding quality and dimensional accuracy of the locomotive floor mat. As the part that directly contacts the floor mat material and forms its shape, the precision and surface quality of the core have a crucial impact on product quality. By adopting a replaceable core structure, the core can be processed and treated individually to ensure that it meets high precision and surface quality requirements. Because the core replacement is convenient, it also reduces the maintenance and repair costs of the mold. When the core is damaged or worn, only the damaged core needs to be replaced, without repairing or replacing the entire mold, saving maintenance time and costs.

[0024] 2. In this utility model, the operation of the motor causes the connecting rod 2 to move the disc 23 upward, achieving the demolding effect. The demolding assembly can quickly separate the motorcycle foot pad from the core after injection molding, reducing the product's dwell time in the mold and thus improving production efficiency. For example, through the action of components such as ejector pins and push pins, the foot pad can be quickly ejected, achieving rapid demolding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a replaceable core structure for a locomotive foot pad mold, including a base plate 1, which serves as the basic support component for the entire mold structure and provides a stable mounting platform for the various components above. A square box 2 is fixedly connected to the top of the base plate 1, providing installation space and stability for the square box 2. A fixing plate 3 is fixedly connected inside the square box 2, which is a box that accommodates and protects the internal structure and provides installation space for the fixing plate 3. A cylinder 4 is fixedly connected inside the fixing plate 3, providing a stable mounting base for the cylinder 4 and preventing displacement or shaking of the cylinder 4 during operation. A fixing block 5 is fixedly connected to the drive end of the cylinder 4, providing power to the fixing block 5 and thereby driving the movement of a series of subsequent components.

[0033] The internal structure of the square box 12 is fixedly connected to a connecting rod 16, ensuring the stability of the entire connection structure and serving as both a connection and support. A connecting plate 17 is rotatably connected to the top of the connecting rod 16, providing a fulcrum for its rotation and thus serving as both a connection and support. Connecting plates 28 are rotatably connected to both ends of the connecting plate 17, transmitting its motion to connecting plates 39. Connecting plates 39 are fixedly connected to the bottom ends of both connecting plates 28, transmitting their motion to the slider 10 and the fixed plate 22, enabling them to perform the corresponding actions according to the design requirements. The bottom of each box is fixedly connected to a slider 10, which serves as a guide and support to ensure the stability and accuracy of the connecting plate 3 9 during movement. The two sides of the inside of the square box 1 2 are fixedly connected to a fixing rod 11, which provides a sliding track for the slider 10 and restricts the movement direction of the slider 10 and the connecting plate 3 9 connected to it. The top of each of the two connecting plates 3 9 is fixedly connected to a fixing plate 2 12, which realizes the operation of fixing, loosening or moving the core through the movement of the connecting plate 3 9. The top of the square box 1 2 is fixedly connected to a demolding component, which is responsible for separating the molded foot pad from the core and ejecting it from the mold, avoiding product damage and time waste that may be caused by manual removal.

[0034] Reference Figures 2 to 4 The demolding assembly includes a square box 2 13, which serves as the load-bearing structure for the demolding assembly. The bottom of the square box 2 13 is fixedly connected to the top of the square box 1 2. The square box 1 2 provides installation space for the square box 2 13 and provides stability for subsequent components. Multiple support columns 1 14 are fixedly connected inside the square box 2 13. The top of the multiple support columns 1 14 is fixedly connected to a fixing plate 3 15. The square box 2 13 supports and positions the fixing plate 3 15, ensuring that the fixing plate 3 15 is in a stable position. A motor 16 is fixedly connected to the rear side of the fixing plate 3 15, providing a stable foundation so that these components will not shift or shake during operation, ensuring the accuracy of the demolding action.

[0035] A ring 17 is fixedly connected to the drive end of motor 16. The operation of motor 16 converts electrical energy into mechanical energy, driving the ring 17 to rotate, which in turn drives the related components. A hollow column 18 is fixedly connected inside the fixed plate 3 15. A connecting rod 2 19 is slidably connected inside the hollow column 18, ensuring precise execution of the demolding action and providing support for the connecting rod 2 19, ensuring its stability during movement. A roller 20 is rotatably connected inside the connecting rod 2 19, converting power into linear motion and driving the connecting rod 2 19 to move up and down. A support plate 21 is fixedly connected to the top left side of the fixed plate 3 15. The hollow column 18 is fixedly connected to the top of the mold, which plays a role in stabilizing the structure and ensuring the accuracy of the demolding action. The spring 22 can play a buffer role to prevent the connecting rod 19 from being damaged by sudden force or excessive speed during the movement. The drive end of the connecting rod 19 is fixedly connected to the disc 23, which can smoothly detach from the mold core 28, ensuring that the foot pad is evenly stressed during the demolding process, avoiding damage or deformation of the foot pad due to excessive local stress, and ensuring product quality. The top of the square box 2 is slidably connected to the mold core 28, and the mold core 28 is cooled and formed in the cavity formed by the other mold components to form the locomotive foot pad.

[0036] Reference Figures 2 to 4 The top of the base plate 1 is fixedly connected to the second support column 24, and the top of the two supports is fixedly connected to the mounting plate 25. The second support column 24 provides vertical support for the mounting plate 25. The top of the mounting plate 25 is fixedly connected to the hydraulic cylinder 26. The drive end of the hydraulic cylinder 26 is fixedly connected to the upper mold 27. The movement of its drive end drives the upper mold 27 to rise or fall. The inner walls of the two sliders 10 are slidably connected to the outer sides of the two fixed rods 11 to ensure the accuracy of their movement direction and to provide movement guidance for components such as the third connecting plate 9. The bottom end of the fixed block 5 is slidably connected to the inside of the square box 1 2 to transmit the power of the drive end of the cylinder 4 to other components. The bottom ends of the two sliders 10 are slidably connected to the top of the square box 1 2 to ensure that the relevant components move smoothly at the top of the square box 1 2. The outer sides of the two fixed plates 12 are slidably connected to the inner wall of the square box 1 2 to play a guiding role and ensure that they slide stably in a specific direction inside the square box 1 2.

[0037] The bottom end of the ring 17 is rotatably connected to the inside of the square box 13 and connected to the drive end of the motor 16, rotating in a circle under the drive of the motor 16. It transmits the rotational power of the motor 16 to components such as the roller 20 that it contacts. The outer side of the disc 23 is slidably connected to the inside of the mold core 28. During the demolding process, when the connecting rod 19 is driven forward by other components, the disc 23 moves accordingly. The left and right sides of the mold core 28 contact the adjacent side of the two fixing plates 12, fixing and positioning the mold core 28, or assisting in the disassembly and installation of the mold core 28 when changing the mold core. The inner wall of the spring 22 is sleeved on the outer side of the connecting rod 19 to assist the connecting rod 19 in resetting and preparing for the next demolding operation. The outer side of the connecting rod 19 is slidably connected to the inside of the support plate 21, and the connecting rod 19 plays a guiding and supporting role. The movement direction of connecting rod 219 is restricted. The outer wall of roller 20 is slidably connected to the top of ring 17. Roller 20 converts the circular motion of ring 17 into its own rolling motion, while driving connecting rod 219 connected to it to make linear motion.

[0038] Working principle: When cylinder 4 is powered on, its driving end extends forward, causing the fixing block 5 to slide forward inside the square box 12. When the fixing block 5 slides, it causes the connecting plate 3 9 to move. The bottom end of the connecting plate 3 9 is connected to the slider 10. When the connecting plate 3 9 moves, it causes the slider 10 to move along the fixing rod 11. The fixing block 5 serves as a limit and guide for the slider 10. When cylinder 4 drives one of the connecting plates 2 8 to move, the other end of one of the connecting plates 2 8 drives the connecting plate 1 7 to rotate. The connecting rod 1 6 inside the connecting plate 1 7 provides stability when the connecting plate 1 7 rotates. The rotation of the connecting rod 1 6 causes the connecting plate 2 8 at the other end to move. The connecting plate 2 8 at the other end provides the movement of the connecting rod 1 6, which drives the component on the other side to move, so that the two fixing plates 2 12 move synchronously, achieving the function of fixing and disassembling.

[0039] When motor 16 is powered on and started, its drive end drives the ring 17 fixed to it to rotate in a circle inside the square box 13. Since the roller 20 is rotatably connected inside the connecting rod 19 and its outer wall slides in contact with the top of the ring 17, the rotation of the ring 17 causes the roller 20 to roll, which in turn drives the connecting rod 19 to slide linearly inside the hollow column 18. At this time, one end of the spring 22 is fixed to the top of the hollow column 18. Its elasticity can buffer the movement of the connecting rod 19 to avoid excessive impact, and can also assist in subsequent connection. When rod 219 is reset, the disk 23 fixed at the drive end of connecting rod 219 moves toward the mold core 28. The outer side of disk 23 slides inside the mold core 28 until disk 23 contacts the locomotive foot pad formed on the mold core 28. Then, the demolding force is applied evenly to push the foot pad off the surface of the mold core 28, completing the demolding operation. Throughout the process, the support column 14 inside square box 213 supports the fixing plate 315 to ensure the stability of the installation position of each component. The support plate 21 plays a guiding and auxiliary supporting role for connecting rod 219.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
