できないという問題点がある。In the above-described conventional method for marking a molded article, when the contact surface between the master 2 and the mounting holes 4 and the screw holes 5 of the mold 3 is burned by heat, the master 2 is removed. There is a problem that it becomes difficult. Furthermore, since the mounting hole 4 and the screw hole of a considerable depth are provided in the mold 3, the cooling water passage of the mold 3 and the location of various pins must be avoided, and the marking position can be set freely. There is a problem that cannot be done.

クを刻設した薄板形の原盤を成形材料の金型の内部での
流動圧力で移動させられることのない取付強度をもって
金型に取付けておき、原盤を成形材料の流動圧力で金型
に押付け固定して、成形品にマークをマーキングする。That is, in the first aspect, a thin plate-shaped master on which a mark to be marked is engraved is attached to a mold with an attachment strength that cannot be moved by the flowing pressure of the molding material inside the mold. The master is pressed and fixed to the mold with the flow pressure of the molding material, and a mark is marked on the molded product.

等が不要になる。In this means, a fixing force of the master to the mold is obtained by utilizing the flow pressure of the molding material. Accordingly, when the flow pressure of the molding material is not acting on the master, the master can be easily removed from the mold. Also, since the master is attached to the mold with an attachment strength that will not be moved by the flow pressure of the molding material, deep mounting holes, etc., where the cooling water channels of the mold and the locations of various pins must be avoided Becomes unnecessary.

【００１４】図１〜図４は、本発明に係る成形品のマー
キング方法の実施の形態（１）を示すものである。FIGS. 1 to 4 show an embodiment (1) of a method for marking a molded article according to the present invention.
【００１５】この実施の形態の原盤２は、金型３の材質

いる。この原盤２は、構造が薄性化，簡素化されるため
安価，容易に製造することができる。The master 2 of this embodiment is formed in a thin plate shape by selecting aluminum, soft iron or the like in relation to the material of the mold 3. The thickness of the master 2 can be reduced to about 0.1 mm. On the surface of the master 2, a mark 1 such as a date of manufacture, a display of a material, a display of a manufacturer or the like is engraved. Since the structure of the master 2 is thinned and simplified, it can be manufactured at low cost and easily.

置を自由に設定することができる。The master 2 is attached to the mold 3 via a double-sided tape 6. The double-sided tape 6 is formed by applying a heat-resistant adhesive 61 to a heat-resistant base paper 62. Since the master 2 is of a thin plate type, it can be attached to a curved portion of the mold 3 as shown in FIG. Further, since it is not necessary to provide a deep mounting hole or the like in the mold 3, there is no restriction on a place where the master 2 is attached to the mold 3. Therefore, the marking position can be set freely.

のため、金型３のキャビティ７を流動する成形材料Ｐ
は、原盤２を越えて流動を継続することになる。A molding material P is placed in a mold 3 on which the master 2 is mounted.
Is supplied, the molding material P flowing through the cavity 7 of the mold 3 comes into contact with the master 2. At this time, FIG.
As shown in the figure, since the temperature of the outer portion Pa of the molding material P that is in contact with the mold 3 is lower than that of the central portion Pb and the fluidity is lower, the outside of the molding material P that has contacted the master 2 is reduced. The portion Pa cannot exert a fluid pressure such that the master 2 is peeled off against the adhesive force of the adhesive 61 of the double-sided tape 6. Therefore, the molding material P flowing through the cavity 7 of the mold 3
Will continue flowing beyond the master 2.
【００１８】そして、金型３のキャビティ７に成形材料
Ｐが充満すると、図２に示すように、原盤２の表面全体
に流動圧力が均等に作用して、原盤２を金型３の強固に
固定することになる。なお、圧縮成形等では、型締め圧
力も原盤２の金型３への固定に寄与する。When the molding material P fills the cavity 7 of the mold 3, the flow pressure acts uniformly on the entire surface of the master 2 as shown in FIG. Will be fixed. In compression molding and the like, the mold clamping pressure also contributes to fixing the master 2 to the mold 3.
【００１９】金型３のキャビティ７に充満した成形材料
Ｐが固化すると、成形品に原盤２のマーク１がマーキン
グされることになる。When the molding material P filling the cavity 7 of the mold 3 is solidified, the mark 1 of the master 2 is marked on the molded product.
【００２０】なお、成形品を金型３から取出した後に

ことができる。After the molded product is removed from the mold 3, the fixing force of the master material 2 by the molding material P is released, so that the adhesive force of the adhesive 61 of the double-sided tape 6 is reduced by a tool such as a peeling knife. The original master 2 can be easily peeled off and replaced.
【００２１】図５，図６は、本発明に係る成形品のマー
キング方法の実施の形態（２）を示すものである。FIGS. 5 and 6 show an embodiment (2) of a method for marking a molded article according to the present invention.

ららなるマーク１が刻設されている。The master 2 of this embodiment includes an outer and upper ring plate 21 and an inner and lower disk 22. The disk 22 is rotatably mounted on the ring plate 21. I have. On the surface of the ring plate 21, "1" to "1" indicating the month are displayed.
A mark 1 consisting of the numeral "2" is engraved. Disk 2
On the surface of No. 2, a mark 1 consisting of a number “96” indicating the year and an arrow is engraved.
【００２３】この実施の形態の両面テープ６は、原盤２

ため、金型３の冷却水路や各種のピンの配設箇所を避け
る配慮は不要である。Since the master 2 is made thicker by the laminated structure of the ring plate 21 and the disk 22, it is preferable to provide the mold 3 with a shallow mounting groove 8. Since the mounting groove 8 is formed shallow, it is not necessary to consider the cooling water channel of the mold 3 and the location of various pins.
【００２６】図７は、本発明に係る成形品のマーキング
