題があった。(Prior art and problems) In recent years, various types of forming such as vacuum forming, vacuum pressure forming, pressure forming, blow forming, injection forming, stamping forming, etc. have been performed using porous bodies such as ceramics sintered bodies and sintered metals. A method for manufacturing a mold that requires air permeability, such as the mold used, has been developed.However, when molding a resin product having a groove on the surface using such a mold, There has been a problem that the model part becomes thin and weak in strength, and the model part is damaged at the time of molding or releasing the resin product.
本考案は、上記の問題を解消すること目的として成され
たものである。The present invention has been made for the purpose of solving the above problems.

挿着して成るものである。(Means for Solving the Problems) In order to achieve the above-mentioned object, the resin molding die of the present invention is such that a groove forming model portion is formed in a protruding manner on a mold body made of a porous body and a large number of ventilation pores are formed. It is formed by inserting a perforated plate-shaped metal partial mold.

要に応じて、適宜形成されている。Here, the porous body means, for example, a ceramic sintered body disclosed in each of the published patent publications such as JP-A-60-166405, JP-A-60-46213, JP-A-61-96008, or the like. It has air permeability like a typical sintered metal and has a required shape formed on the upper surface. In addition, with the plate-shaped metal partial mold,
The metal partial mold surface is obtained by forming a groove-forming model portion in a projecting position at a required position by using a sheet metal press, a thermal spraying method, an electroforming method, etc., forming a plate shape, and forming a number of ventilation pores. A reverse grain pattern for skin grain forming is appropriately formed by an etching method or the like as necessary.
なお、溶射法や電鋳法による金属製部分型は、周端部を

As shown in FIG. 1, a required shape on the surface and an anchor portion (3) of a metal partial die (4) described later are provided. ) Is formed on the upper surface of the mold body (2) made of a ceramics sintered body having the recesses (1) and (1) for bending the plate material at both left and right sides upward as shown in FIG. Partial metal mold (4) that forms the model parts (4a) (4b) and is press-molded into the required shape, and anchors (3) (3) are fixed to the required positions on the lower surface.
As shown in FIG. 3, recess the anchor parts (3) (3) (1)
After mounting with (1) interposing epoxy resin, for example,
When the mold body (2) is attached to the box body (5) having the ventilation hole (5a), the required resin molding mold can be obtained.

優れた実用的効果を奏する。(Effect of the Invention) As is apparent from the above description, according to the present invention, the groove-forming model portion is formed by projecting on the mold body made of a porous material having a gas permeability such as a ceramics sintered body or a sintered metal. In addition, since it is a resin molding mold that is equipped with a plate-shaped metal partial mold in which a large number of ventilation pores are drilled, the groove molding model part may be damaged when molding or releasing the resin product. It has excellent practical effects such as disappearing completely.
