To provide a resin molded product having a desired surface shape, a resin molding mold which can manufacture the resin molded product and a method of manufacturing the same, and a resin molding mold manufacturing system to achieve manufacturing of the resin molding mold, a resin molding mold according to the present invention includes a molding mold main body and a resin layer exposedly formed on a mold surface side of the molding mold main body, made of a heat-resistant complex material containing a synthetic resin, and a ceramic powder particle, and having a thickness of 50 to 800 μm. The resin molding mold according to the present invention includes the molding mold main body and the resin layer exposedly formed on the mold surface side of the molding mold main body and made of the heat-resistant composite materials including a synthetic resin, and the ceramic powder particle, and recesses and projections are formed on the resin layer by excavating a portion of the resin layer.

Resin molding die, method for manufacturing resin molding die, method for manufacturing resin molded article, and system for manufacturing resin molded article

A molding die includes a die having a mold plane; and gloss control granules composed of 50 to 80 pbw of a shape retention fixation base material such as a thermosetting resin; 30 to 80 pbw of a diffuse reflecting surface formation core material such as a ceramic powder; and 5 to 10 pbw of a roughness enhancement material such as an inorganic fiber, adhered to the mold plane in a spaced-apart manner. The gloss control granules are each independently adhered in the spaced-apart manner to form gloss control projections on the mold plane of the die so that a surface of a molded product molded on the die forms a surface having a small specular reflection or a diffuse reflection, and the gloss control projections having fine, uneven surfaces with recesses and projections are formed on the mold plane at a coating rate of 40 to 80%.

Molding die and method for manufacturing same

Provided is a mold part for resin molding and a manufacturing method. A mold part for molding resin includes a base material layer, a design section and uneven sections which abut an inner surface so as to form ventilation sections. The design section has a design surface transferred by a reverse master having an uneven surface. At least the design section out of the base material layer and the design section is formed of a heat resistant material, and the mold part for resin molding is interchangeably attached to the molding tool so that a molding pressure acts in a direction to press the uneven sections against the inner surface of the molding tool at the time of molding the resin molded article.

Method of manufacturing a mold part

A method of manufacturing an decoration film includes the steps of forming a semi-finished decoration film formed with a concave-convex pattern on a surface in a method of manufacturing a printing plate including exposure, cleaning, and drying from a photosensitive resin film; and irradiating laser on the concave-convex pattern of the semi-finished decoration film and removing an unnecessary portion to smooth concave-convex parts and/or provide difference in height of a convex part and depth of a concave part of the concave-convex pattern.

Product with concave-convex pattern on its surface and method of forming the concave-convex pattern

A plastics shaping mold comprising a layer of hardened resin material fixedly superposed on a metal mold and defining an uneven shaping surface for forming an uneven surface pattern on plastic articles. The plastics shaping mold is prepared by a method comprising the steps of superposing a resin material in a fluid state on a master in sheet form defining an uneven surface inverse to the uneven shaping surface to be formed, allowing the resin material to harden and removing the master, thereby to form the layer of hardened resin material defining the uneven shaping surface.
