When the 3rd mobile core 160 is driven by independent external driver device, because the anglec of rotation of rotary core 150 can arbitrarily regulate, undercut portions U can be configured to the curvature with reduction, and in other words, undercut portions U can be configured to progressive circle.
In other words, as shown in Fig. 3 to 8D, according to the molding apparatus 100 of an exemplary of the present disclosure, because rotary core 150 can automatic rotation when the first mobile core 130 advances, a part for bend 152 can circumferentially giving prominence at the first mobile core 130.Therefore, when bend 152 extends a little and the distance that the bend 152 of the first mobile core 130 is given prominence in a circumferential direction increases, the width of the assembly that the first mobile core 130, second mobile core 140 and rotary core 150 are bonded to each other may be greater than the width of the inner space 112 of mold component 110, and causes core insert action difficulty.
Therefore, as mentioned above, when the 3rd mobile core 160 drives independent of the first mobile core 130, the anglec of rotation of rotary core 150 can be controlled when described core inserts, make bend 152 circumferentially giving prominence to not at the first mobile core 130.
Although more than show and describe exemplary, but it should be apparent to those skilled in the art that under the condition not deviating from the spirit and scope of the present disclosure that claims limit, can modifications and variations be made.
