Manufacturing method and application of multilayer product hot-melting connecting structure

Abstract

The invention discloses a manufacturing method and application of a multilayer product hot-melting connecting structure. Single-layer or multi-layer intermediates are clamped in the middle mainly through hot-melting connection of a first connector and a hot-melting connector, the aim of one-time connection and combination is achieved, various structural layers can be bonded without a complex bonding process, and the production efficiency of multilayer product combination is improved. The application field is wide, the production efficiency can be further simplified and improved by combining anejection process, another application path of a hot-melting ejection process is created, and meanwhile application products in multiple fields are provided, wherein the application products can be produced through the manufacturing method of the hot-melting connecting structure and can improve production efficiency; the machining time of products in various fields can be greatly reduced, and themanufacturing cost can be greatly reduced; and the application field is wide, huge market application prospects are achieved, and the overall productivity level of the society can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of hot-melt injection machine manufacturing, and in particular relates to a manufacturing method and application of a multi-layer product hot-melt connection structure. Background technique [0002] With the improvement of living standards, people have a greater demand for the diversity of daily necessities and industrial products; most of the products are composed of multi-layer structures; such as cushions, outer skin decoration, inner elastic foam , bottom support board, etc.; under normal conditions, these multi-level structures are connected by bonding, seaming and other processes; such as the shoe manufacturing field, including soles and uppers; soles may include outsoles and midsoles Wait, the outsole needs to be bonded to the midsole to form the sole, and the sole needs to be bonded to the upper to form it; this traditional shoe bonding process not only needs to connect the two together, but also nee...

[0002] With the improvement of living standards, people have a greater demand for the diversity of daily necessities and industrial products; most of the products are composed of multi-layer structures; such as cushions, outer skin decoration, inner elastic foam , bottom support board, etc.; under normal conditions, these multi-level structures are connected by bonding, seaming and other processes; such as the shoe manufacturing field, including soles and uppers; soles may include outsoles and midsoles Wait, the outsole needs to be bonded to the midsole to form the sole, and the sole needs to be bonded to the upper to form it; this traditional shoe bonding process not only needs to connect the two together, but also needs to ensure that there is a certain gap between the connecting layers. The connection strength is not easy to peel off, so the process is more complicated; for example, the bonding of traditional shoes needs to go through a treatment agent on the bonding surface, drying, brushing glue, drying, brushing glue, pressing the bottom, shaping, cooling, . The connection structure of multi-level products makes the connection process complicated, which is no longer suitable for future development forms

[0003] Plastic injection molding process, in existing applications, can integrally inject a certain shape of objects; it can also inject a hot melt liquid in a molten state to the surface of another solid material, and after the hot melt liquid cools, the formed The hot-melt solid is directly shaped and attached to another solid material. The surface of the solid material melts at high temperature, and the part in contact with the hot-melt liquid achieves a chemical fusion connection; To a certain extent, the use of injection technology has achieved the effect of improving production efficiency, but the connection structure of the above-mentioned plastic injection molding process is only used for direct injection molding of object 1 and adhesive connection to object 2 to form a product; it cannot achieve one-time Multiple levels of connection composition; such as figure 1 As shown, for example, a product is a combination of structural layer 1, structural layer 2, and structural layer 3. Using the existing injection technology, structural layer 1 can be selected for injection molding, and structural layer 1 can be directly attached to structural layer 2. , while the connection between the other structural layer 3 and the structural layer 1 or 2 still needs to be connected through another injection or bonding process; the purpose of connecting the structural layers 1, 2, and 3 by one injection cannot be achieved; What's more, in a product, the structural layer 2 may be a multi-layer structure, so it is even more impossible to connect them into a whole with one injection in the existing injection technology
