Description

One-piece formed plastic shell skating shoes

Technical Field

The invention relates to the technical field of ice skate and roller skate manufacturing, in particular to an integrally formed plastic shell ice skate.

Background

Skates include skates and roller skates, which are shoes worn during skating or roller skating (roller skating). The prior art skates are those having a skate blade assembly or a pulley assembly mounted to the sole of the skate. It is a competition appliance for sports competition and is also a shoe appliance widely used for leisure sports.

The traditional manufacturing process of the ice skate and the roller skate is generally that only the plastic shell part is formed on a mould during injection molding, but the inner sleeve of the shoe cannot be formed. The inner sleeve part of the shoe is particularly complex in manufacturing process, and different cut pieces need to be cut, then the cut pieces are marked and covered with edges, and finally the cut pieces are spliced and sewn by sewing. Because the inside of the shoe is a curved surface, the sewing machine has higher operation difficulty, and the problems of needle skipping, uneven line distance, asymmetry of the inner side and the outer side and the like are easy to occur; in the process of turning the sealing sheet, the phenomena of connection dislocation and wrinkle are easy to occur. For the inner sleeve of the shoe in places with different thicknesses and hardness, the traditional method adopts a sheared paperboard as a positioning reference to remove a line, and then adopts a sewing paster and a glue brushing paster to realize the connection of the shell and the inner sleeve of the shoe. In the process of brushing glue in the forming process, the artificial glue is usually not aligned with the midline, the artificial glue is distorted, and the glue used for brushing the glue is harmful to the health of human bodies.

Therefore, the existing skating shoe manufacturing process has the defects of complicated steps, low quality efficiency, high manufacturing cost, difficulty in accurate connection, environmental pollution and inconvenience for the health and ecological environment protection of staff.
