Description

Technical Field

[0001] This utility model relates to the field of footwear production mold technology, specifically a three-dimensional casual shoe upper coating molding mold. Background Technology

[0002] In the footwear manufacturing industry, the demand for high-quality laminated molding of 3D casual shoe uppers is constantly growing. However, existing shoe upper lamination molding dies have some significant problems in use.

[0003] In footwear manufacturing, traditional demolding methods often rely on simple mechanical structures. This method is prone to uneven stress on the shoe upper, causing deformation, tearing, or adhesion to the mold during demolding. Due to the roughness of the mold surface, the stickiness of the molding material, and unreasonable mold structure design, demolding often becomes difficult and unreliable. This not only affects production efficiency and increases the scrap rate, but may also lead to unstable product quality, increasing subsequent repair and processing work. It is difficult to ensure the consistency of force and direction for each demolding, which not only easily causes damage and deformation to the shoe upper, but also seriously affects production efficiency.

[0004] For example, a three-dimensional shoe upper coating molding die, as disclosed in announcement number CN116619805A, has an inner cavity within the die body that matches the flyknit sock to be shaped. The die body has a pressure heating device, and a last is used to fit the flyknit sock and is placed within the die cavity to attach the coating material to the flyknit sock. External equipment is connected to the last to shape the flyknit sock. When coating and molding flyknit socks, this three-dimensional shoe upper coating molding die relies on complex machinery or manual labor for demolding, resulting in low efficiency, high cost, easy damage to the shoe upper, and unstable quality. However, it also has other problems. In previous shoe... During the lamination process, the laminating material is usually applied to the shoe surface manually. However, manual operation has many limitations. It is difficult to ensure the positional accuracy and uniformity of the laminating material, and deviations and wrinkles are prone to occur. Manual operation is inefficient, especially in large-scale production, becoming a bottleneck in the production process. Because human attention cannot be maintained at a high level for a long time, problems such as uneven lamination, wrinkles, and bubbles are very likely to occur, which greatly affects the quality and appearance of the product. Insufficient control makes it impossible to guarantee the uniformity and consistency of the laminating material, which not only increases production costs but also seriously affects the production schedule, leading to unstable product quality. Utility Model Content

[0005] The purpose of this utility model is to provide a three-dimensional casual shoe upper coating molding die to solve the problems mentioned in the background art, such as the reliance on complex machinery or manual labor for demolding, which results in low efficiency, high cost, easy damage to the shoe upper and unstable quality, and the slow speed, poor quality and high cost of manual or simple equipment operation for coating material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional casual shoe upper coating molding die, comprising a mold shell and a lower mold fixedly installed on the upper end of the mold shell; the lower end of the mold shell has a placement groove, and the upper end of the lower mold has a placement hole, and a pushing block is nested in the placement hole on the lower mold, and two pushing blocks are evenly distributed with the mold shell as the center of symmetry; an automatic demolding mechanism is provided at the lower end of the mold shell, and an extrusion rod is fixedly installed at the lower end of the pushing block, and two extrusion rods are evenly distributed with the lower mold as the center of symmetry; a first support frame is fixedly installed on the front side of the upper end of the mold shell, and a coating material is rotatably installed on the upper end of the first support frame; an automatic feeding mechanism is provided at the lower end of the mold shell, and a second support frame is fixedly installed on the rear side of the upper end of the mold shell.

[0007] Furthermore, the automatic demolding mechanism includes an extrusion plate fixedly installed at the lower end of the extrusion rod, and the extrusion plate is disposed inside the placement groove at the lower end of the mold shell. A return spring is installed on the outside of the extrusion rod, and the return spring is disposed between the lower mold and the extrusion plate. A contact rod is rotatably installed on the right end of the lower mold.

[0008] Furthermore, the contact rod has two molds evenly distributed at a symmetrical center. The lower end of the lower mold corresponds to the lower end of the extrusion plate. A limit rod is fixedly installed on the right side of the upper end of the lower mold, and an upper mold is provided on the upper end of the limit rod. The upper mold and the lower mold correspond to each other.

[0009] Furthermore, a compression spring is provided on the outer side of the limiting rod, and the compression spring is located between the lower mold and the upper mold. A push wheel is fixedly installed in the middle of the right end of the lower mold, and the push wheel cooperates with the inner side of the contact rod. A discharge port is fixedly installed at the front end of the lower mold, and the middle of the discharge port is installed at the lower end of the mold shell.

[0010] Furthermore, the automatic feeding mechanism includes a receiving column rotatably mounted on the upper end of the second support frame, and the receiving column cooperates with the coating material. An electric motor is provided on the inner side of the lower end of the second support frame, and the electric motor is fixedly installed on the upper left side of the mold shell.

[0011] Furthermore, a drive pulley is rotatably mounted on the lower left side of the second support frame, and the drive pulley is connected to the output end of the motor. A drive column is fixedly mounted on the left side of the drive pulley.

[0012] Furthermore, a driven indirect wheel is rotatably mounted on the upper left side of the second support frame, and the driven indirect wheel is connected to the receiving column. The driven indirect wheel has a drive groove, and the drive groove cooperates with the drive column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the shoe upper is placed on the lower mold, the coating material covers the shoe upper. Then, the stamping device presses the upper mold limit rod downward, and the lower mold cooperates with the upper mold to cover the shoe upper with the coating material. The compression spring pushes the upper mold to reset, causing the upper mold to move upward and separate from the lower mold. The push wheels at both ends of the upper mold move, and the push wheels contact and push the contact rod on the lower mold to rotate. The extrusion rod then pushes the push block, so that the shoe upper with the coating completed on the lower mold can be smoothly demolded. Automatic demolding reduces damage to the shoe upper, improves production efficiency, ensures safety, and reduces costs.

[0015] Furthermore, it enables precise and stable demolding operations, greatly reducing minor damage to the shoe upper caused by improper demolding, ensuring that the upper of every pair of shoes meets high-quality standards, and significantly improving the demolding speed. The demolding process that used to take several minutes or even longer can now be completed in just tens of seconds, greatly shortening the production cycle and effectively improving the operating efficiency of the entire production line, enabling companies to produce more high-quality products in the same amount of time.

[0016] Furthermore, it avoids various accidental injuries that may be caused by manual operation, providing workers with a safer and more reliable working environment, significantly reducing the labor intensity of workers, freeing them from heavy and dangerous demolding work, while also reducing the company's labor costs, improving the safety of the production process, effectively preventing accidents caused by sudden uneven force, and greatly reducing the probability of workplace accidents, allowing companies to achieve efficient and high-quality production under the premise of safe production.

[0017] 2. Before the shoe upper is covered with the film material, the output end of the motor drives the active indirect pulley to rotate. The active indirect pulley drives the drive column on the left end to rotate. When the drive column is inserted into the drive groove, the drive column drives the driven indirect pulley to rotate through the drive groove. The driven indirect pulley drives the material receiving column at the upper end of the second support frame to rotate. The material receiving column rolls up the film material on the first support frame, so that the film material covers the shoe upper. Automatic application of film material ensures uniform quality, improves efficiency, and reduces defect rate and cost.

[0018] Furthermore, the automatic covering device can precisely position and cover the covering material onto the shoe surface, ensuring accurate positioning and no deviation. This improves the quality and consistency of the covering, increases work speed, shortens the production cycle, meets the high-efficiency requirements of large-scale production, avoids wrinkles and unevenness that may occur with manual covering, makes the covering adhere more tightly and smoothly to the shoe surface, improves the product appearance quality, reduces labor and management costs, and maintains a stable covering effect regardless of human factors.

The pressure plate 8 and the extrusion plate 8 are located inside the groove at the lower end of the mold shell 1. A return spring 9 is installed on the outside of the extrusion rod 4 and is located between the lower mold 2 and the extrusion plate 8. A contact rod 10 is rotatably installed on the right end of the lower mold 2. Two contact rods 10 are evenly distributed with the lower mold 2 as symmetrical centers. The lower end of the lower mold 2 corresponds to the lower end of the extrusion plate 8. A limit rod 11 is fixedly installed on the right side of the upper end of the lower mold 2, and an upper mold 12 is set on the upper end of the limit rod 11.

A drive groove 21 is opened on the driven indirect pulley 20, and the drive groove 21 cooperates with the drive column 19.

[0031] Before the shoe upper is covered with the film material 6, the output end of the motor 17 drives the active indirect pulley 18 to rotate. The active indirect pulley 18 drives the drive column 19 at the left end to rotate. When the drive column 19 is inserted into the drive groove 21, the drive column 19 drives the driven indirect pulley 20 to rotate through the drive groove 21. The driven indirect pulley 20 drives the material receiving column 16 at the upper end of the second support frame 7 to rotate. The material receiving column 16 rolls up the film material 6 on the first support frame 5, so that the film material 6 covers the shoe upper.
