Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to suitcases, cosmetic cases, home appliances,
This invention relates to a method of manufacturing a resin molded product integrally formed with a lining material used for furniture, automobile instrument panels, automobile door inner surface materials, etc.

[Background technology and its problems] In recent years, in order to improve the appearance of products, so-called lining products, in which raised cloth materials, various leather products, artificial leather, etc. are stretched over the surface of resin molded parts, have been widely used. ing.

Conventional manufacturing methods for such lined products include fixing the lining material to the surface of a resin product that has been pressure-molded into a predetermined shape by gluing or crimping, or installing the lining material in a mold and then injecting it. It is made by an integral molding method. At this time, if a material with a lining material integrally molded on the surface of the resin sheet is used and the material is heated and deformed in a press, the edges of the finished molded product may have parts that are not covered with the lining material. This method may not be possible at all depending on the shape of the product, as it may cause the edges where the lining material was not originally placed to be exposed on the surface of the molded product, significantly impairing its appearance. It was hot. In addition, in the case of injection molding, workability is poor due to tensioning of the lining material, etc., and especially in the case of large products, the lining material may be deformed due to resin flow within the mold, which tends to cause poor appearance. It takes a long time to cool the mold,
Productivity was extremely low.

In order to improve these conventional drawbacks, JP-A-Sho
The invention described in Publication No. 55-5900 has been proposed. According to this publication, the edge of the resin material is cut off during press molding using a special mold, and the lining material is cut off by a predetermined size larger than this edge, thereby forming the edge of the resin molded member. This method eliminates the uncovered portion of the lining material by making it possible to wrap the lining material with a lining material cut larger than the end shape. Although this method can provide a molded product with a good appearance, there is a problem in that productivity is not necessarily good. That is, since both the resin material and the lining material use sheet materials cut to a predetermined size, a continuous molding line cannot be constructed, resulting in poor mass productivity. In addition, the lining material that has been cut out is removed in the post-process of the lining material cutting process.
It is necessary to bend the resin molded product along its periphery as a separate process, which also poses the problem of poor productivity.

[Object of the invention] The object of the present invention is to provide a finished product with a good appearance;
Further, it is an object of the present invention to provide a method for manufacturing an integrally molded product with a lining material that can be continuously produced and has excellent mass productivity.

[Means and effects for solving the problems] The present invention supplies a continuous lining material to a production line having at least two stages of press sections, a first and a second stage, and a press section located on the supply side of the lining material. A resin material in a thermoplastically processable state is supplied to a first press section, and the resin material and the lining material are integrally fused and molded by the first press section to form a resin molded member, and the lining is The lining material is integrally formed by punching the lining material by bringing the male die and the female die of the second press part close together so that a lining material of a predetermined width exists around the resin molded member integrally molded with the material. Manufacture molded products,
Further, during this press punching, a predetermined width of the lining material existing around the resin molded member is bent along the periphery of the resin molded member at the bending end inside the female mold recess, and The above objective is achieved by discharging the scraps of the lining material in a continuous state, thereby making it possible to manufacture integrally molded products of the lining material one after another in a series of continuous production lines. .
