Description

Technical Field

[0001] This utility model relates to the field of mold opening and closing technology, and in particular to an opening and closing device for a shoe sole mold. Background Technology

[0002] Because shoe soles have complex shapes and contours, molds are typically used to produce soles in order to ensure that each sole accurately reflects the shape required by the design, such as the textured surface of athletic shoe soles and the smooth curve of leather shoe soles. This ensures a perfect match between the sole and the upper, as well as the overall aesthetics and comfort of the shoe, and facilitates large-scale production of the soles.

[0003] As is well known, molds generally consist of a moving mold and a fixed mold. In the production of shoe soles using molds, the moving mold needs to be moved relative to the fixed mold to open and close the mold, allowing raw materials to be added into the mold or the molded shoe sole to be removed from the mold. For example, in the production of PU shoe soles, the mixed material is quickly poured into the moving and fixed molds, which are located far apart from each other. Then, the moving mold is snapped onto the fixed mold, allowing them to be joined to form the shoe sole molding space, thereby producing a qualified shoe sole product.

[0004] To achieve large-scale, high-efficiency production of shoe soles, the transmission system used to control the movement of the moving mold relative to the fixed mold is mostly manually operated. This means that at least three employees are distributed across the production line holding multiple sets of molds. One employee operates the PU sole material pouring equipment, pouring the PU sole material into the fixed mold. The other two employees are positioned upstream and downstream of the pouring equipment. The employee upstream controls the moving mold to detach from the fixed mold and disassemble the finished shoe sole, while the employee downstream controls the engagement of the moving mold with the fixed mold, thus creating the molding space and allowing the PU sole material to solidify and solidify.

[0005] The aforementioned method of manually controlling the opening and closing of the fixed and moving molds requires a significant amount of physical labor and time to complete the mold opening and closing actions. This is not only inefficient but also prone to inconsistencies in the degree of mold opening and closing due to differences in human operation, thereby affecting the molding accuracy of the shoe sole and increasing the product defect rate. At the same time, prolonged high-intensity manual operation can cause worker fatigue and increase the risk of safety accidents. Utility Model Content

[0006] This utility model discloses an opening and closing device for a shoe sole mold, which mainly solves the problems of low efficiency and high labor intensity of manual operation of shoe sole mold opening and closing.

[0045] like Figure 1As shown, in order to change the current situation of manually opening and closing the shoe sole mold 1, reduce the labor intensity of workers, and correspondingly improve the efficiency of shoe sole production, this embodiment provides a device for opening and closing the shoe sole mold 1. This device can control multiple sets of shoe sole molds 1 to move along their preset trajectory, and when the shoe sole mold 1 moves to a certain node (such as a casting device), it controls the moving mold to move relative to the fixed mold, thereby realizing the opening and closing of the shoe sole mold 1. This allows a single worker to easily inject raw materials into the mold 1 and shape them under the action of the mold 1.

[0046] like Figure 1 As shown, specifically, the opening device includes a base 2, a support mechanism 4, a lower pressure plate 5, and a guide rail 3. Both the support mechanism 4 and the guide rail 3 are positioned above the base 2, with the guide rail 3 positioned above the support mechanism 4. The lower pressure plate 5 is positioned between the support mechanism 4 and the guide rail 3. To meet the needs of large-scale shoe sole production, multiple sets of lower pressure plates 5 are provided, and these sets are movably positioned below the guide rail 3, directly opposite multiple areas of the lower pressure plate 5 and the support mechanism 4. The mold 1 is then installed within the space formed by the areas where the lower pressure plate 5 and the support mechanism 4 are directly opposite each other. Therefore, under the action of the support mechanism 4, the lower pressure plate 5 and the mold 1 are controlled to move along a preset trajectory, and the lower pressure plate 5 is controlled to rise and fall during the movement to facilitate the opening and closing of the mold 1. The preset trajectory can be set as a circular trajectory or a trajectory similar to a playground shape (i.e., an ellipse composed of a rectangle and two semicircles). To accommodate different walking trajectories, the support mechanism 4 and the guide rail 3 can be set to the required shapes as needed.

[0047] like Figure 1-7 As shown, when the travel trajectory is circular, the support mechanism 4 includes a main board 41 and multiple sets of support plates 43. The main board 41 is configured as a ring structure, and the multiple sets of support plates 43 are located on the outer side of the main board 41 and distributed along the circumference of the main board 41. In addition, the lower pressure plate 5 is directly opposite the support plates 43. Therefore, the fixed mold of the mold 1 is installed on the support plate 43, and the moving mold of the mold 1 is installed on the lower pressure plate 5. That is, the lower pressure plate 5 and the support plates 43 are respectively located on the upper and lower sides of the mold 1. Therefore, when the main board 41 rotates, the support plates 43 and the lower pressure plate 5 can be controlled to move synchronously, thereby changing the position of the multiple sets of molds 1 and controlling the multiple sets of molds 1 to pass through the raw material casting equipment in sequence.

[0048] To control the rotation of the main board 41, a vertical tube 21 is installed above the base 2. A bracket 22 is mounted on the vertical tube 21, and a motor (which can be a servo motor, stepper motor, etc.) is invertedly mounted on the bracket 22. A drive gear 23 is mounted on the motor's power output shaft. A central tube 45 is located inside the main board 41 and is connected to the vertical tube 21 via a bearing. A gear ring 42 is located at the bottom of the central tube 45 and meshes with the drive gear 23. Therefore, when the motor is running, the drive gear 23 can be controlled to rotate. Because the drive gear 23 meshes with the gear ring 42, the main board 41 is controlled to rotate around the central axis, thereby adjusting the position of the multiple sets of support plates 43. Additionally, an electrical control box can be installed on the base 2 and connected to the motor to provide power for its operation. The electrical control box is a publicly available device and generally includes at least a circuit breaker, contactor, relay, and controller (such as a PLC) to control the motor's operation.

[0049] In order to control the movement of the moving mold of the mold 1 as the lower pressure plate 5 moves with the main plate 41, the guide rail 3 includes a pressing part 31 and a lifting part 33, which are joined together to form a closed travel trajectory. At the same time, a hook 6 is provided above the lower pressure plate 5 and is sleeved on the guide rail 3. Therefore, as the lower pressure plate 5 rotates with the main plate 41, the hook 6 moves between the pressing part 31 and the lifting part 33. Thus, by utilizing the structural characteristics of the guide rail 3, the moving mold is controlled to rise and fall relative to the fixed mold, thereby realizing the opening and closing of the mold 1.

[0050] In order to control the stable installation of the guide rail 3, a sleeve 32 is provided on the inner side of the pressing part 31. The sleeve 32 is connected to the top of the vertical tube 21 by bolts. Therefore, under the action of the sleeve 32, the guide rail 3 can be stably installed above the base 2.

[0051] With the guide rail 3 stably installed, in order to enable the hook 6 to move along the circumference of the guide rail 3, the hook 6 is set as an arc-shaped column structure with a central angle greater than or equal to 180°, and the hook 6 is sleeved on the guide rail 3. Therefore, the existence of the notch in the hook 6 allows it to pass through the plate between the sleeve 32 and the guide rail 3, avoiding the presence of the plate affecting the movement of the hook 6.

[0052] In addition, a connecting plate 61 is fixedly installed below the connecting hook 6. The connecting plate 61 is installed on the inner side of the lower pressure plate 5 by bolts, so as to achieve a stable connection between the connecting hook 6 and the lower pressure plate 5.

[0053] To ensure the relatively stable setting of the fixed mold and the moving mold of mold 1, an ear plate 51 is fixedly provided at the end of the lower pressure plate 5. A limiting rod 53 is provided at the ear plate 51 through a threaded post 52. The limiting rod 53 is provided through the through hole 44 of the support plate 43. Therefore, with the cooperation of the limiting rod 53 and the through hole 44, the position of the lower pressure plate 5 relative to the support plate 43 can be limited without affecting the lifting and lowering of the lower pressure plate 5 relative to the support plate 43, thus facilitating the movement of the moving mold relative to the fixed mold.

[0054] When the travel trajectory is elliptical, the pressing part 31 is set as an ellipse with a notch, and a lifting part 33 is installed at the notch, with the lifting part 33 located on the straight segment of the ellipse. At least two sets of elliptical columns are provided below the guide rail 3, distributed inside and outside the column body. The two ends of each column are respectively mounted on two bases 2, ensuring stable installation of the elliptical columns. This allows them to be connected to multiple support plates 43 via hooks 6, thus ensuring stable installation of the fixed mold of the mold 1 relative to the columns. This also facilitates movement of the fixed mold along the elliptical direction of the columns, meaning the support plate 43 is not directly connected to the main plate 41. Furthermore, the support mechanism 4 has two sets, each with a main plate 41 equipped with corresponding components, allowing the main plate 41 to function as a sprocket or pulley. A chain or belt is fitted between the two main plates 41, connected to the support plate 43. Therefore, when the motor controls the chain or belt to rotate, it controls the support plate 43 to move the mold 1 and the pressing plate 5. The remaining structural settings refer to the technical solution where the walking trajectory is circular.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0056] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
