適した方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a molded article, and molding materials include synthetic resins such as thermoplastic resins and thermosetting resins, fiber-reinforced synthetic resins, and inorganic molding materials such as cement and plaster. The present invention relates to a method suitable for manufacturing a molded product in which a female thread is provided in a portion formed by a mold surface portion that is inclined with respect to the mold opening direction.

いる。 Conventionally, when manufacturing a molded product to which a female thread is attached, for example, in addition to determining the position of the female thread on the mold surface, a protrusion, etc. for temporary fixing is provided, and this protrusion, etc. is attached to a metal or synthetic resin. A molded product with a female thread attached thereto is manufactured by fitting the tip of a female thread made of a metal thread, etc., closing the mold, and shaping the molding material placed inside the mold.

きた。 However, according to the conventional method, if a female thread is provided in a mold surface part that is inclined with respect to the mold opening direction, the depth direction of the female thread will be in a direction different from the mold opening direction of the mold, so that the molded product will be damaged. When the mold is removed from the mold, the female thread is caught in the protrusion and cannot be removed, resulting in a disadvantage that a desired molded product having the female thread cannot be obtained. However, it is often necessary for the molded product to have an internal thread attached to the part to be molded by the mold surface part that is inclined with respect to the mold opening direction, so a molding device that can mold such a molded product is required. A model has been desired.
本発明は、成形用型の型開き方向に対して傾き
を有する型面部分により成形される部分に雌ねじ
が取付けられている成形物を製造する方法を提供
することを目的とするものである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing a molded product in which a female thread is attached to a portion formed by a mold surface portion that is inclined with respect to the mold opening direction of a mold.
次に本発明成形物の製造方法の一例を図面に基
いて説明する。 Next, an example of the method for manufacturing the molded article of the present invention will be explained based on the drawings.
１は成形用型であり、型部１１，１２よりな

夫々有し、型部１１と型部１２が閉合された際に
所望の成形物形状に適合する型窩が形成される。
又、型部１１，１２は型開き方向Ａに対して傾き
を有する型面部分１３，１４を有している。 Reference numeral 1 denotes a mold for molding, which consists of mold parts 11 and 12. The mold part 11 has a convex surface, and the mold part 12 has a concave surface, and when the mold parts 11 and 12 are closed, a mold cavity is formed that fits the shape of the desired molded product.
Further, the mold parts 11 and 12 have mold surface portions 13 and 14 that are inclined with respect to the mold opening direction A.
このような成形用型１により、雌ねじ２が取付

とができないものとなる。 If a molded article 6 to which a female thread 2 is attached is to be molded using such a mold 1, it is necessary to position the female thread 2 so that it does not move due to the flow of the molding material. For this purpose, a protrusion is provided on the mold surface of the molding die 1 into which the female thread 2 can be fitted. When the female threads 2 are provided on the mold surface portions 15 and 16, the mold opening direction A is the same as the direction in which the female threads 2 come out of the projections, so it is not easy to remove the molded product 6 from the mold 1. be. However, if the female threads 2 are provided in the mold surface portions 13 and 14 that are inclined with respect to the mold opening direction A of the mold 1, the female screws 2 may get caught in the protrusions when the mold is opened, and the molded product 6 may not be molded. It becomes impossible to break away from type 1.
そこで本発明では型開き方向Ａに対して傾きを
有する型面部分１３，１４により成形される部分
に雌ねじ２が取付けられた成形物６を得ることが
できるように、型面１３に、開口縁に面取が施さ

嵌着される。 Therefore, in the present invention, in order to obtain a molded product 6 in which the internal thread 2 is attached to the part to be molded by the mold surface parts 13 and 14 that are inclined with respect to the mold opening direction A, an opening edge is provided on the mold surface 13. A chamfered cylindrical recess 3 is provided, and a magnet 4 is fitted into the recess 3, which has a conical recess 41 at one end at an angle that does not create an undercut with respect to the mold opening direction A. It will be worn.
５は、前記凹陥部４１に挿嵌可能な截頭円錐形

が嵌着されている。 5 is an iron female screw having a truncated conical head 52 that can be inserted into the recessed part 41, and a flange 51 is provided outwardly at the base of the threaded part, and a circular flange is provided on the flange surface. A concave groove is bored in the concave groove, and an O-ring 53 is inserted into the concave groove.
is fitted.
型部１１，１２が開かれている状態で、型開き
方向Ａに対して傾きを有する型面部分１３に嵌着
された磁石４の円錐形凹陥部４１に、予め雌ねじ
２に螺着された雄ねじ５の頭部５２を挿嵌吸着す
る。次いで型内に成形材料を供給する。 When the mold parts 11 and 12 are open, the female screw 2 is screwed in advance into the conical recess 41 of the magnet 4 fitted to the mold surface part 13 that is inclined with respect to the mold opening direction A. The head 52 of the male screw 5 is inserted and attracted. Next, a molding material is supplied into the mold.

石膏等の無機質成形材料を使用することもでき
る。 For example, when molding a synthetic resin molded product, the mold part 1
1 and 12 are closed, a thermoplastic resin or a thermosetting resin is injected into the mold from a resin injection port provided in either of the mold parts 11 and 12, and the mold is shaped. or,
If a fibrous mat such as glass fiber is placed in a mold in advance and resin is injected and shaped, a molded product reinforced with fibers can be obtained. Furthermore, a molded product reinforced with fibers can also be obtained by supplying fibrous mat impregnated with a thermosetting resin in advance into a mold, closing the mold, and performing compression molding. . As molding materials, cement,
Inorganic molding materials such as plaster can also be used.
成形物６を型部１１，１２から離脱させる際
は、型開き後成形物６を型開き方向Ａに引抜く。 When removing the molded product 6 from the mold parts 11 and 12, the molded product 6 is pulled out in the mold opening direction A after opening the mold.
磁石４の凹陥部４１は型開き方向Ａに対してア
ンダーカツトとならない角度となされているため
に、雄ねじ５の頭部は磁石４から型開き方向Ａに
離脱できるので成形物６を離脱させることができ
る。離型後雄ねじ５を雌ねじ２より離脱させる。 Since the concave portion 41 of the magnet 4 is formed at an angle that does not create an undercut with respect to the mold opening direction A, the head of the male screw 5 can be detached from the magnet 4 in the mold opening direction A, so that the molded product 6 can be detached. I can do it. After releasing the mold, the male screw 5 is separated from the female screw 2.

る。 According to the present invention, it is possible to manufacture a molded product in which a female thread is attached to a portion formed by a mold surface portion that is inclined with respect to the mold opening direction of a mold. Further, since the position of the female screw is carried out by inserting and attracting the head of the male screw screwed onto the female screw into the concave portion of the magnet, it is easy to remove the molded product from the mold. Further, when a male thread provided with a flange and an O-ring is screwed onto a female thread as in the embodiment, there is an advantage that resin does not enter the threaded part.
