性に欠ける。Plastic molded products are used in large quantities in all fields including automobiles and home appliances due to their economic efficiency, free formability, and fg:fi properties. It has disadvantages such as easy scratching, and there has been a strong demand for decoration, softness, etc.
In the past, various studies have been made to obtain compounds with functions that satisfy these demands, but it has been found that a single material that maintains free formability and strength while improving the surface properties of the above-mentioned drawbacks. However, at present, multilayer molded products that combine multiple materials with different functions are commonly used. [Problems to be solved by the invention] Various molding methods have been proposed as a method for integrally molding using Multilayer molded products obtained by integral molding using thermoplastic resins generally have the problem that the texture of the woven or nonwoven fabric is significantly damaged by pressure and/or heat. 0 This problem can be solved by low-pressure molding using a press molding method, which can be significantly improved over injection molding methods, and it may be possible to put it into practical use by selecting woven or non-woven fabrics. , nonwoven fabrics are limited and lack diversity.

される。The purpose of the present invention is to improve the shortcomings of these conventional methods and provide a method for rationally integrally molding a multilayer molded product with a good texture using a wide range of woven or nonwoven fabrics. [Means for Solving the Problems] The present invention is directed to a thermoplastic resin in a molten state, a woven fabric or a non-woven fabric C with a backing material lined on the back side, or a backing material on the back side of a thermoplastic resin, a woven fabric or a non-woven fabric C, or (including laminated sheets, films, various foams, papers, etc.) is supplied between molds, and the thermoplastic resin and the woven fabric or non-woven fabric are laminated together by applying pressure and cooling. ◇ The mold cavity surface used in the present invention is a molding method characterized by using a mold in which a fine uneven pattern is provided on the mold cavity surface that comes into contact with the woven or nonwoven fabric. The fine unevenness pattern is similar to the grain pattern of various patterns used to give a fine unevenness pattern to the surface of molded products in injection molding of thermoplastic resin, etc. The pitch, depth, etc. of the unevenness are adjusted depending on the type of skin material.

に成形操作について説明する。The upper mold cavity surface (11) K is provided with an uneven pattern. 0 (8) is the lower puften of the press machine, to which the lower mold for molding (4) is attached. The lower mold is provided with a heat-retained resin passage (5) through which the molten resin passes, and this resin passage (6) is connected to the tip of an injection device that supplies the molten resin, although it is not shown in the figure. has been done. Although not shown, the supply port (7) is provided with a valve that opens when the molten resin is supplied and closes when the supply is finished.Next, the molding operation will be explained.

Lower the upper platen further and separate the upper mold (2) and lower mold (
In step 4), the molten resin is pressed and shaped as shown in FIG. 8 to obtain a laminate molded product (22) in which the woven or nonwoven fabric (20) and the resin (21) are laminated together.

どめるのがよい。In this molding method, when the upper mold cavity surface is a flat surface, the woven fabric or nonwoven fabric is uniformly crimped on the flat surface, so the texture of the woven fabric or nonwoven fabric is generally likely to be impaired. , when using a mold with a fine unevenness pattern on the surface of the upper mold cavity, the woven fabric or nonwoven fabric mainly forms the convex portions ( 12) is crimped with the lower mold cavity surface, and is relatively difficult to be crimped in the recesses of the upper mold cavity surface. Therefore, the texture of the woven fabric or nonwoven fabric as a whole is easily maintained. A material with a small pitch and a deep depth is more suitable for wood purposes, but there are also problems with workability, so it is best to keep it to the extent necessary depending on the characteristics of the skin material.
剛性が高く、肉厚の厚い織布または不織布を用いる場合

は一層向上する。When using a highly rigid and thick woven fabric or non-woven fabric, good results can be obtained with an upper mold that has a relatively large pitch and shallow uneven surface.〇In addition, a backing material etc. is laminated on the back side. When a woven or nonwoven fabric is used, retention of texture is further improved.
