Since the lock pin 2 is placed near the sprue bush 4 in the area close to the sprue bush 4, there are problems in that the position of the gate sprue 1 is wide and the amount of resin in the runner 6 is large.
発明の目的
本発明は従来の欠点を解消するものであり構成を簡素化
するものである。OBJECTS OF THE INVENTION The present invention overcomes the drawbacks of the prior art and simplifies the construction.

樹脂量を少なくすることができるものである。Structure of the Invention The mold device of the present invention comprises a plate for ejecting the cavities and runners constituting the gate sprue, a lock pin for separating the gate sprue from the product, a plate for fixing the lock pin and the sprue bush, and the sprue. , and a sprue bushing with an undercut at the tip to separate the gate sprue from the product, avoiding the need to place a lock pin to avoid the sprue bushing.
Since the sprue bush has an undercut, the pitch of the gate nut is reduced and the amount of 3-vane resin in the runner can be reduced.
実施例の説明 以下に本発明の実施例を第２図にもとづいて説明する。Description of examples An embodiment of the present invention will be described below based on FIG.

りはなれる。In the figure, 6 is a nuburu fish, the end is a lock pin,
8 is a plate for fixing 6 and 7, 9 is a runner, 10 and 11 are gate sprues, 12 and 16 are products, 13 is a sprue, and 14 is a plate for ejecting 9, 10, 11, and 13. The tip of 6 has an under force and throat structure to separate 11 and 12. When opening the mold, 6 is fixed to 8, and 11 and 12 are fixed due to the undercut 17 at the tip.
is cut, 10 and 15 are cut by undercut 18, and 9, 11, and 10 are attached to 14 and separated from plate 16.
次に１４により９と１０と１１と１３と６の先端部のア

The undercut 17 at the tip of 6 and the undercut 18 at the tip of 7 are separated from 9.
ただし、第２図の６で先端部のアンダーカットの形状は
凸になっているが凹でもよく、要はアンダーカット形状
であればよい。However, although the shape of the undercut at the tip is convex at 6 in FIG. 2, it may be concave, and any undercut shape is sufficient.
