Description

Technical Field

[0001] This utility model relates to the technical field of shoe upper shaping machines, specifically a 3D shoe upper shaping machine. Background Technology

[0002] The 3D shoe upper shaping machine is a key shoe manufacturing equipment that integrates curl shaping, bonding and ironing. By precisely controlling the temperature, pressure and time, and with the help of customized 3D molds, it completes the three-dimensional shaping of the shoe upper. Its core principle is to use hot pressing technology to shape the flat shoe upper material according to the preset shoe shape arc and curved contour, so that the shoe upper maintains a stable 3D three-dimensional structure after cooling, which fits the curve of the foot.

[0003] 3D shoe upper shaping machine can adapt to the characteristics and requirements of different materials. Compared with the traditional method of hand shaping after flat cutting, 3D shoe upper shaping machine can significantly improve the fit between shoe upper and shoe last, reduce wrinkles and errors during subsequent sewing and assembly, and enhance the structural stability and durability of shoe upper. It can efficiently realize personalized shoe design and is one of the important equipment for the transformation of the shoe manufacturing industry towards intelligent and flexible production.

[0004] The 3D shoe upper shaping machine requires placing the shoe upper on the lower mold first, and then shaping it by pressing down with the upper mold. This operation needs to be performed twice. However, the specifications of the lower mold are usually in a fixed state, and the key parameters of its forming surface and contour size are preset fixed values. This structural characteristic makes it difficult for the lower mold to adapt to different shoe shapes or special process requirements, which significantly restricts the flexible production scenarios of multiple specifications and small batches, and reduces the equipment's adaptability to diverse processing tasks. Therefore, a 3D shoe upper shaping machine is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a 3D shoe upper shaping machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A hydraulic cylinder is mounted on the top front side of the shaping frame, and an upper pressure mold is fixedly mounted on the bottom output end of the hydraulic cylinder. A lower mold assembly is located on the front side of the shaping frame and at its bottom. A drive assembly is located on the front side of the lower mold assembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A 3D shoe upper shaping machine includes a machine base 1 and two shaping components 2. The shaping component 2 includes a shaping frame 21. A hydraulic cylinder 22 is installed on the top front side of the shaping frame 21. An upper pressure mold 23 is fixedly installed at the bottom output end of the hydraulic cylinder 22. A lower mold component 3 is provided on the front side and bottom side of the shaping frame 21. A drive component 4 is provided on the front side of the lower mold component 3. The lower mold component 3 includes a lower mold support plate 31. The lower mold support plate 31 is arranged in an inverted "V" shape. The inner cavity of the lower mold support plate 31 is provided with two pairs of adjusting tooth seats 32. The two pairs of adjusting tooth seats 32 are symmetrically arranged front and back. The opposite surfaces of the adjusting tooth seats 32 are provided with adjusting external teeth 33. Adjacent adjusting tooth seats 32 are connected by the meshing of adjusting external teeth 33. The outer side of the adjusting tooth seat 32 is fixedly connected to the inner side of the lower mold support plate 31. The shaping component 2 is fixedly installed on the top rear side of the machine base 1, and the drive component 4 is fixedly installed on the top front side of the machine base 1.

[0026] As a further implementation of this solution, a transmission rod 34 is fixedly inserted through the center of each adjusting gear seat 32. The rear end of the transmission rod 34 is rotatably connected to the bottom of the front wall of the shaping frame 21. In the above configuration, the transmission rod 34 can support the adjusting gear seat 32 through its connection with the shaping frame 21 and can synchronously drive the adjusting gear seat 32 to rotate.

[0027] As a further implementation of this solution, the drive assembly 4 includes a synchronous belt 41. The synchronous belt 41 has synchronous pulleys 42 symmetrically arranged at both ends of its inner cavity. The synchronous belt 41 and the synchronous pulleys 42 are meshed and connected. The distance between the two synchronous pulleys 42 is the same as the distance between the adjusting gear seats 32 on the same side of the inner cavity of the two lower mold support plates 31. The two synchronous pulleys 42 and the adjusting gear seats 32 on the same side of the inner cavity of the two lower mold support plates 31 are concentrically arranged. In the above arrangement, when one synchronous pulley 42 rotates, it can drive the other synchronous pulley 42 to rotate synchronously through the synchronous belt 41. At the same time, the concentric arrangement of the synchronous pulleys 42 and the adjusting gear seats 32 can provide the basic conditions for the subsequent synchronous pulleys 42 to drive the adjusting gear seats 32 to rotate synchronously.

[0028] As a further implementation of this solution, a pair of fixed brackets 43 are provided at both ends of the front side of the synchronous belt 41, which are arranged symmetrically on the left and right. The center of the front wall of the synchronous pulley 42 is rotatably connected to the top of the rear side of the fixed bracket 43 through a connecting short rod. In the above arrangement, the fixed bracket 43 can connect and support the synchronous pulley 42.

[0029] As a further implementation of this solution, the front ends of the transmission rods 34 on the same side of the two shaping frames 21 extend to the front side of the lower mold support plate 31, and this end is fixedly connected to the center of the rear wall of the adjacent synchronous wheel 42. The front side of the fixed bracket 43 is provided with a self-locking handwheel 44. The rear side of the self-locking handwheel 44 is fixedly connected to the top of the front side of the fixed bracket 43 through a connecting short rod. The self-locking handwheel 44 and the adjacent synchronous wheel 42 are concentrically arranged. In the above arrangement, the self-locking handwheel 44 can drive the adjacent synchronous wheel 42 to rotate, and the opening degree of the lower mold support plate 31 can be adjusted after transmission.

[0030] Workflow: First, the shoe upper material needs to be placed on the lower mold support plate 31 in the lower mold assembly 3. Then, the hydraulic cylinder 22 on the top front side of the shaping frame 21 in the shaping assembly 2 is activated, causing the upper mold 23 to press down. After being pressed down by the upper mold 23, the shoe upper material will form a 3D shape that matches the shape of the lower mold support plate 31. When facing different shoe shape requirements, the opening degree of the lower mold support plate 31 needs to be adjusted. During adjustment, the self-locking handwheel 44 in the drive assembly 4 is rotated. The self-locking handwheel 44 will drive the synchronous pulley 42 on the rear side of the adjacent fixed bracket 43 to rotate. This synchronization will drive another synchronous pulley 42 to rotate through the meshing rotation of the synchronous belt 41. The synchronous rotation of the synchronous pulleys 42 will simultaneously drive the transmission rods 34 to rotate. The transmission rods 34 in the two lower mold assemblies 3 will drive the adjustment gear seats 32 on their respective parts to rotate. The rotation of the adjustment gear seats 32 will drive the other adjustment gear seat 32 to rotate in the opposite direction through the meshing connection of the external adjustment teeth 33. At this time, the two adjustment gear seats 32 will simultaneously expand outward or close inward. The lower mold support plate 31 is made of a material with a certain degree of elasticity, so it will adjust the opening and closing degree according to the expansion or closing of the adjustment gear seats 32, thereby reducing the constraints on flexible production scenarios with multiple specifications and small batches, and improving the equipment's adaptability to diverse processing tasks.

[0031] It is worth noting that since the pressing process of the shoe upper material by the two shaping components 2 needs to be performed once before and once after, in order to ensure the 3D shaping effect of the shoe upper material, when adjusting the opening and closing degree of the lower mold support plate 31, it is necessary to ensure that the opening and closing degree of the two lower mold support plates 31 is adjusted in a consistent manner. The setting of the drive component 4 can adjust the opening and closing degree of the two lower mold support plates 31 synchronously, preventing the opening and closing degree of the two lower mold support plates 31 from deviating, thus ensuring the shaping effect.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
