行う方法と金型装置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention holds an insert by a holding pin provided in a cavity so as to be retractable.
The present invention relates to a method and a mold apparatus for performing injection molding by filling the cavity with resin.

ィ外に没入させて樹脂から抜き出している。In this type of insert molding method, the insert inserted when the mold is opened is held in the cavity by the forward movement of the holding pin after the mold is closed, and then the insert side gate is used. Resin is injection-filled around the insert, and after filling, the holding pin is immersed in the outside of the cavity and extracted from the resin.

二次的に射出充填して行い、それによりピン跡が残らな
いようにしている。In such a molding method, when the holding pin is extracted after the resin is cooled and solidified, pin marks remain on the surface of the molded product as holes. These pin marks often result in defects that are favorable for products, and as a solution to this problem, the holding pin is pulled out earlier before the resin solidifies, and the holding pin fills the unfilled portion of the resin from the injection device. Is secondarily injected and filled so that no pin marks remain.

て設定位置からずれ、不良品となることが多い。However, due to the backward movement of the holding pin, the insert is not fixed but supported only by the resin having fluidity, and is in a state of being easily moved together with the resin. When the cavity is filled from the injection device, the insert moves in the resin flow direction due to the filling pressure, that is, in the direction opposite to the gate due to the resin pressure and shifts from the set position, often resulting in a defective product.

法と金型装置とを提供することある。The present invention has been conceived in order to solve the above-mentioned conventional problems, and an object thereof is to fill an unfilled portion of a resin by a holding pin by press-fitting the resin by a pressing pin after injection filling. By doing so, it is possible to prevent the movement of the insert due to the resin pressure at the time of filling, and to provide a new method and a mold device that can insert-mold a product without defects due to pin marks.

入して補填用樹脂２１ａとして蓄えられる。After the mold is clamped, the resin 21 which has been plasticized and measured in advance in the tip of the injection device 6 is injected and filled from the sprue 8 through the gate 5 on the parting into the cavity 4 by the forward movement of the injection screw 7. The resin 21 flows in the upper and lower spaces of the insert 20 from the side of the cavity to fill the cavity 4, and a part of the resin also flows into the pin holes 13 and 14 and is stored as the filling resin 21a.

サート２０が横ずれするようになる。When the injection and filling of the resin 21 is completed, the holding pins 9 and 10 and the pressing pins 15 and 16 are moved relative to each other, so that the portions not filled with the resin are filled by the pressing pins 15 and 16. As shown, the injection pressure P when the filling is completed
1 is higher than the cavity internal pressure P 2 , and when the holding pins 9 and 10 are moved into and out of the cavity as they are, the resin 21 on the injection device side flows into the cavity side from the gate 5 due to the pressure difference, fills the unfilled portion and the resin flow. Occurs, and the insert 20 is laterally displaced.

ティ内の樹脂２１に強制的に押し入れられる。Therefore, as shown in FIG. 7, the injection pressure P 1 is lowered to near the cavity internal pressure P 2 to prevent the resin 21 from flowing into the cavity from the injection device side.
The retracting movement of the holding pins 9 and 10 and the forward movement of the pressing pins 15 and 16 are performed by simultaneously operating the hydraulic cylinders. As a result, the resin 21a for filling the pin holes 13 and 14 is forced into the resin 21 in the cavity.

This solves the conventional problem of lateral displacement of the insert 20, which tends to occur in the injection device side due to press-fitting of the resin, and the unfilled portion is surely filled with the backward movement of the pressure-holding pins 9 and 10. It becomes an insert-molded product with pin marks completely filled.
