Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to suitcases, converted eaves boxes, RNs, products, furniture,
This invention relates to a method of manufacturing a resin molded product integrally formed with a lining material used for 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 could not be used at all depending on the shape of the product, as the end portion to which the lining material was not originally applied could be exposed to the surface of the molded product, resulting in a significant deterioration of the appearance. 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 took a long time to cool the mold, and productivity was extremely low.

In order to improve such conventional drawbacks, Japanese Patent Application Laid-Open No. 55-5
The invention described in Japanese Patent No. 900 has been proposed. According to this publication, the edge of the resin material is cut off during press molding using a special metal, and the lining material is also cut off by a predetermined size larger than this edge, thereby cutting off 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 in a large size must be bent along the periphery of the resin molded product in a separate process after the lining material cutting process, which also poses the problem of poor productivity. be.

[Purpose of the invention] The purpose of the invention is to provide a finished product with good appearance.

Moreover, 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 has the following features:
Using a continuous lining material, a resin material is integrally fused to this continuous lining member by press molding to form a resin molded member, and around the resin molded member integrally molded with this lining material. , a lining material integrally molded product is manufactured by press punching the lining material so that a lining material of a predetermined width is present, and the lining material is formed around the resin molded member using the stroke of the press during this press punching. The lining material of a predetermined width is bent along the periphery of the resin molded member, and the scraps of the lining material are discharged in a continuous state,
