AI Technical Summary
Existing shoe toe compression molds have a short service life and are prone to irreversible deformation, resulting in a poor tightening effect between the shoe toe and the outsole tip, increasing production costs and reducing work efficiency.
An expansion notch is made at the top center of the rear end of the shoe toe counter-pressure mold, and a limiting plate is installed on the top surface. The limiting plate is fixedly connected to the front of the counter-pressure mold with screws. The width of the limiting plate matches the width of the shoe toe, ensuring that the deformation of the mold is concentrated in the center and avoiding lateral deformation.
It extended the service life of the mold, improved the tightening effect between the toe and the outsole, reduced production costs, and increased work efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shoe manufacturing equipment, and relates to the process of tightening the toe and outsole, specifically to a shoe toe reverse pressure mold. Background Technology
[0002] In shoe production, bonding the upper to the sole is a common method. The bonding process typically involves manually applying glue to the upper and sole, then pressing them together while still hot in a shoe press machine to achieve adhesion. The toe and outsole tip also require a soft rubber mold. The outer walls of the toe and outsole tip are encased in the mold, while the inner walls are held in place by the shoe last. The mold deforms inward under pressure to tighten the toe and outsole tip. During operation, the mold continuously deforms, especially on the sides. Although a stretch notch at the top center of the rear end helps reduce deformation, irreversible deformation can still occur, leading to a decrease in the tightness between the toe and outsole tip. This necessitates frequent mold replacement, reducing efficiency and increasing production costs. Utility Model Content
[0003] This invention aims to solve the problem of short lifespan of the shoe toe counter-pressing mold used in shoe pressing during the shoe manufacturing process, and provides a shoe toe counter-pressing mold with a simple structure and long service life.
[0004] The technical solutions for achieving the above objectives include the following:
[0005] A shoe toe compression mold has a telescopic notch at the center of its rear top. The top surface of the compression mold is provided with a limiting plate. The bottom surface of the limiting plate is attached to the top surface of the compression mold. The limiting plate is narrower at the front and wider at the back. The left and right sides of the limiting plate are arc-shaped. The left and right width of the limiting plate is smaller than the left and right width of the top surface of the compression mold. The left and right width of the limiting plate matches the left and right width of the shoe toe to be processed. The front part of the limiting plate is fixedly connected to the front part of the compression mold.
[0006] Furthermore, the front part of the limiting plate is fixedly connected to the front part of the counter-pressure mold by screws, and the front part of the limiting plate is provided with more than three through holes through which the screws are inserted.
[0007] Furthermore, the thickness of the limiting plate is 2-4mm.
[0008] Furthermore, the limiting plate is a steel plate.
[0009] Furthermore, the material of the counter-pressure mold is urethane.
[0010] When the above-mentioned shoe toe counter-pressure mold is in use, the shoe toe and outsole tip are wrapped by the counter-pressure mold. When the shoe press applies force to the counter-pressure mold from the outside, the counter-pressure mold deforms towards the center, and the telescopic notch shrinks. Since a limiting plate is installed on its top, the two sides of the counter-pressure mold are oriented to deform only towards the center, effectively ensuring irreversible deformation, thereby extending the service life of the counter-pressure mold. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the shoe toe counter-pressure mold structure for an embodiment.
[0012] In the diagram: 1. Expansion notch; 2. Limiting plate; 3. Bolt. Detailed Implementation
[0013] The present invention will be described in detail below with reference to the embodiments.
[0014] See Figure 1 A shoe toe compression mold made of urethane has a telescopic notch 1 at the center of the top rear end. The top surface of the compression mold is provided with a steel limiting plate 2, which is 3mm thick. The bottom surface of the limiting plate 2 is attached to the top surface of the compression mold. The limiting plate 2 is narrower at the front and wider at the back. The left and right sides of the limiting plate are arc-shaped. The left and right widths of the limiting plate 2 are smaller than the left and right widths of the top surface of the compression mold to ensure that it does not hinder the squeezing action of the shoe press machine. The left and right widths of the limiting plate 2 match the left and right widths of the shoe toe to be processed. The front part of the limiting plate 2 is fixedly connected to the front part of the compression mold by three bolts 3.
[0015] When the shoe toe counter-pressure mold of this utility model is working in the shoe pressing machine, it wraps around the toe and outsole of the shoe. The two sides of the counter-pressure mold are squeezed and converge towards the center, and the telescopic notch 1 closes. The limiting plate 2 on the top surface ensures that the top of the counter-pressure mold will not tilt upwards and deform, ensuring that the outsole tip can be subjected to uniform force synchronously. The counter-pressure mold is constrained under the limiting plate 2 to prevent deformation, thus preventing irreversible deformation and effectively improving the service life of the entire counter-pressure mold. The shoe toe counter-pressure mold of this embodiment still maintains its original shape after pressing 6,000 pairs of shoes, while the counter-pressure mold of the prior art can only press about 2,000 pairs of shoes before needing to be replaced. This proves that the service life of the shoe toe counter-pressure mold of this embodiment is significantly improved, which can effectively reduce production costs and has good market prospects and application value.
