が公知である。Conventionally, mold release devices for threaded molded products such as threaded caps have been equipped with a threaded portion on the peripheral surface of the tip of a core that is loosely inserted into a cavity plate to form a cavity. After molding the attached product, the core is rotated in order to extract the threaded part of the core from the screw of the molded product in order to release the molded product, and this rotation mechanism uses a gear machine configuration or a rack and pinion mechanism. A method using the following is known.
然し乍ら、これら装置は設備の大型化を生じ省スペース
の点で問題がある。However, these devices have problems in terms of space saving as the equipment becomes larger.

プレートを雌雄ネジにより適合させ、移動プレーI・を
コアの軸方向に移動させることによってコアを軸回り方
向に回動せしめる機構が推考される処である。In a drum, a mechanism is proposed in which the core is inserted into a movable plate, the core and plate are matched with male and female screws, and the core is rotated around the axis by moving the movable plate I in the axial direction of the core. This is where you will be treated.

適合状態に左右されてしまう。However, in this case, since the position of the moving plate must be set in advance to a specific position, the position in the rotational direction of the core is determined by the female and male screws, and the rotational direction of the threaded portion formed at the tip of the core is determined by the male and female screws. The position also depends on the compatibility of the female and male screws.

に回動調整且つ固定自在として戒る点にある。In view of the above, the object of the present invention is to provide a device that can accurately mold the threaded part of a threaded molded product in a predetermined direction and position and release the mold. The core is loosely inserted into the plate to form a cavity, and the core is provided with a threaded portion on the distal end circumferential surface thereof, and the core is inserted through the movable plate,
In order to rotate the core around the axis by moving the movable plate in the axial direction of the core, the movable plate is provided with a female screw, and the core is provided with a male screw that matches the female screw, and the female and male screws are connected to each other. The point is that at least one of them should be rotatably adjustable and fixable in the circumferential direction.

阻止している。This female screw member 19 is internally fitted and locked to the movable plate 18 via a stepped portion 20 of different diameter, and is rotatably adjustable and fixed in the circumferential direction via splines 21 formed as many as possible. A lock plate 23 that is removably bonded to the movable plate 18 with a fixing member 22 such as a bolt prevents the female screw member 19 from coming out of the movable plate 18.
第3図は本考案の変形実施例を示しており、コア1の軸
心に沿ってランナー26を形成し、該ランナー26をコ
ア1の頭部頂面よりキャビティ16に開口させている。FIG. 3 shows a modified embodiment of the present invention, in which a runner 26 is formed along the axis of the core 1, and the runner 26 opens into the cavity 16 from the top surface of the head of the core 1.
従ってキャビティプレート14はランナーを有しないも
のとされている。Therefore, the cavity plate 14 does not have a runner.
その他の構成は上記実施例と同様であり、同一符号で示
している。The other configurations are the same as those in the above embodiment and are indicated by the same reference numerals.

ビティプレート14を移動してコア1の頭部8より離隔
せしめると共に、移動プレート1Bを進出(図面に於て
上方に)移動させる。To release the molded product 25, move the cavity plate 14 to separate it from the head 8 of the core 1 as shown in the second figure, and move the movable plate 1B forward (upward in the drawing). let
このとき移動プレート1Bの移動に伴ない雌雄ネジ10
を介してコア1が成形品25からネジ部9を抜出す方向
に回転される。At this time, as the moving plate 1B moves, the female and male screws 10
The core 1 is rotated in the direction in which the threaded portion 9 is extracted from the molded product 25 via the .
同時にストリッパプレートト11がスプリング13によ
り成形品25をコア1の頭部8がら抜出す方向に押上げ
、これにより成形品25が成形された雌ネジ24を損傷
することなく離型される。At the same time, the stripper plate 11 pushes up the molded product 25 by the spring 13 in a direction to extract it from the head 8 of the core 1, whereby the molded product 25 is released from the mold without damaging the female thread 24 formed therein.
再度成形品25を成形するには、第1図示の如く、移動
プレート1Bを所定の元位置に復帰移動させた後、キャ
ビティプレート14をコア1の頭部8を被冠するよう移
動し、上記と同様にして成形及び離型が反復される。To mold the molded product 25 again, as shown in the first figure, after moving the movable plate 1B back to the predetermined original position, move the cavity plate 14 so as to cover the head 8 of the core 1, and then repeat the steps described above. Molding and mold release are repeated in the same manner.
このようにして得られた成形品25は、例えば゛ネジ付
キャップであり、第4図示の如く化粧品容器27の口部
28に螺着施蓋され、キャップ25の周面に一体又は別
体に付設されたマーク29が容器27の正面マーク30
と同一方向に面するものとされている。The molded product 25 thus obtained is, for example, a screw cap, which is screwed onto the opening 28 of the cosmetic container 27 as shown in the fourth figure, and is attached integrally or separately to the circumferential surface of the cap 25. The attached mark 29 is the front mark 30 of the container 27
shall face in the same direction.
従ってキャップ25を容器27に完全に螺着した状態で
前記両マーク29、30の方向が一致しなければ不良品
とされ、成形品25を廃棄しなければならない結果とな
る。Therefore, if the directions of the marks 29 and 30 do not match when the cap 25 is completely screwed onto the container 27, it will be considered a defective product and the molded product 25 will have to be discarded.
而して成形品25に所定の雌ネジ24を成形するには、
第1図示の成形状態時にコア1のネジ部9が周方向に対
し特定位置に設置されていなければならない。Therefore, in order to form a predetermined female thread 24 on the molded product 25,
In the molding state shown in the first figure, the threaded portion 9 of the core 1 must be placed at a specific position in the circumferential direction.
このとき移動プレート1Bは装置の設計上作動位置及び
ストロークが予じめ設定されており、この設定された状
態でコア1と雌ネジ部材19とが螺合していなければな
らない。At this time, the operating position and stroke of the movable plate 1B are set in advance due to the design of the device, and the core 1 and the female screw member 19 must be screwed together in this set state.
本考案ではこの場合、雌ネジ部材19をスプライン21

つ離型することができる。In this case, in the present invention, the female screw member 19 is connected to the spline 21.
Rotation can be adjusted in the circumferential direction through the , and a predetermined female pear 24 can be molded and released from the molded product 25 in a desired set state.
本考案は以上のように構成した結果、バックアッププレ
ート2とホルダプレート5との間のスペースを有効に利
用して移動プレート1Bを設けたので、設備の小型化を
可能として省スペースに有利である。As a result of the above-described configuration of the present invention, the space between the backup plate 2 and the holder plate 5 is effectively used to provide the movable plate 1B, so that it is possible to downsize the equipment and is advantageous in saving space. .
しかも移動プレー) 1Bの移動に連動してコア1を回

機構等の直接にコア1を回転させるものに比して構造が
簡単であり、該移動プレート1Bをキャビティプレート
14と連動連結しておけば動力源も単一ですむ利点があ
る。Moreover, since the core 1 is rotated in conjunction with the movement of the moving play) 1B, the structure is simpler than those that directly rotate the core 1, such as a conventional gear machine configuration or a rack and pinion mechanism. If the moving plate 1B is interlocked with the cavity plate 14, there is an advantage that a single power source is required.
更に雌ネジ部材19が周方向に回動調整且つ固定自在と

4を成形することができる効果がある。Furthermore, since the female screw member 19 can be rotated and fixed in the circumferential direction, for example, when the molded product 25, which is a screw cap, is screwed onto the container 27, the cap 25 can be fixed.
The female screw 2 is inserted into the molded product 25 at a predetermined position so that the mark 29 faces the same direction as the mark 30 on the container 27.
It has the effect of being able to mold 4.
