【考案の詳細な説明】
本考案は成形型内で芯材と合成樹脂を一体に成
形するに際し、芯材を支持するための装置に関
し、シリンダー１のロツド２の先端に、型８内の
芯材３を支持するピン４の基部５が結合されると
共に、ピン４にピン４の基部５と下型６間に介在
されたスプリング７が巻着されて成るものであ
る。而して、図中８は型、９は合成樹脂である。[Detailed description of the invention] The present invention relates to a device for supporting the core material when integrally molding the core material and synthetic resin in a mold. A base 5 of a pin 4 supporting the material 3 is connected to the pin 4, and a spring 7 interposed between the base 5 of the pin 4 and a lower die 6 is wound around the pin 4. In the figure, 8 is a mold, and 9 is a synthetic resin.
従来、成形型内で芯材を支持するピンは、合成
樹脂が充填された後、ピンを後退させるためにシ
リンダーを積極的に作動させていたので、切り換
えのタイミングやそれらの装備も必要とされたの
である。 Conventionally, the pins that support the core material in the mold have been filled with synthetic resin, and a cylinder has been actively operated to move the pins back, so timing and equipment for switching are also required. It was.
そこで本考案は、芯材の支持が不要になつた時
に、即ピンを後退させ、適切な合成樹脂の流入を
はかつたもので、その作用を図面に基づき説明す
れば、型８内の芯材３をピン４で支持することに
より、ピン４は安定し、合成樹脂９の流体の流し
込みにも不動となる。この時、スプリング７は押
圧され、第１図の如く縮んでいる。 Therefore, in the present invention, when the core material no longer needs to be supported, the pin is immediately retracted to allow an appropriate flow of synthetic resin. By supporting the material 3 with the pin 4, the pin 4 is stable and does not move even when the fluid of the synthetic resin 9 is poured. At this time, the spring 7 is pressed and compressed as shown in FIG.
而して、ある程度合成樹脂９が入充して芯材３
がピン４の支持がなくともその位置が保てるよう
になつたときに、シリンダー１の圧を除けば、ス
プリング７は反発し、ピン４の基部５を押し下
げ、ピン４を型外に後退させるのである（第２図
に示す）。 As a result, the synthetic resin 9 is filled to some extent to form the core material 3.
When the pin 4 can maintain its position without the support of the pin 4, when the pressure of the cylinder 1 is removed, the spring 7 rebounds and pushes down the base 5 of the pin 4, causing the pin 4 to retreat out of the mold. (as shown in Figure 2).
叙上の如く、本考案はピン４を支持していたシ
リンダー１の圧を除くと同時に、スプリング７に
よりピン４を後退させるものであるから、その作
用正確であつて、合成樹脂９の流入を適切にして
成形をする有用な考案である。 As mentioned above, in the present invention, the pressure of the cylinder 1 supporting the pin 4 is removed and at the same time the pin 4 is moved back by the spring 7, so the operation is accurate and the inflow of the synthetic resin 9 is prevented. This is a useful idea for proper molding.

れたスプリング７が巻着されて成る、合成樹脂成
形型に於ける芯材支持装置。 A base 5 of a pin 4 supporting a core material 3 in a mold 8 is connected to the tips of the cylinder 1 and rod 2, and a spring 7 interposed between the base 5 of the pin 4 and a lower mold 6 is attached to the pin 4. A core support device in a synthetic resin mold that is wrapped around the core.
