As the locking block 510 retreats with respect to the injection product P, the first slide core 311 in close contact with the locking block 510 in the closed state of the mold device 100 responds to the movement of the locking block 510 Thus, it is possible to retreat with respect to the injection product P.

In the foregoing, for convenience of description, a method for adjusting the position of the first slide core 311 using the position adjusting member 500 has been described. The second slide core 312 may also be adjusted in the same way as the position adjustment method of the first slide core 311 .

The second slide core 312 finely moves the locking block 510 by a user manipulating the other end 522b of the fixing unit 552 included in the position adjusting unit 520 of the position adjusting member 500 described above. Based on FIG. 3 , it may be moved in the Y-axis direction. Accordingly, the position of the second slide core 312 may be finely adjusted in the Y-axis direction. For example, when the fixing unit 522 moves in the +Z direction based on FIG. 4 by manipulating the other end 522b, the auxiliary block 521 is attached to one end 522a of the fixing unit 522. It is supported by and can move in the +Z direction based on FIG. 4 .

As supported, normal stress due to injection pressure may be resolved into shear stress along the first inclined surface 530 . Accordingly, shear stress corresponding to a portion of the injection pressure may be applied to the fixing unit 522 . On the other hand, when the fixing unit 522 is disposed in the X-axis direction or the Y-axis direction with respect to the auxiliary block 521 as shown in FIG. 4 , vertical stress corresponding to the injection pressure may be applied to the fixing unit 522 as it is. there is.

In addition, as the auxiliary block 521 is disposed on the positioning member 500, the user can finely adjust the position of the locking block 510 of the positioning member 500. For example, when the fixing unit 522 is coupled to the locking block 510 in the X-axis direction based on FIG. 4 rather than the auxiliary block 521, the locking block 510 is the fixing unit 522 is the X-axis You can move as much as you move in that direction. Therefore, it may be difficult to finely adjust the position of the locking block 510 using the fixing unit 522 . On the other hand, as in the present invention, when the fixed unit 522 is coupled to the auxiliary block 521 by being positioned in the -Z direction with respect to the auxiliary block 511, the auxiliary block 521 is the Z axis of the fixed unit 522 It may move in the Z-axis direction along the second inclined surface 531 formed on the first mold base 112 in response to the movement in the direction. Accordingly, the locking block 510 connected to the auxiliary block 511 may move forward or backward with respect to the injection product P minutely by the inclination angle of the second inclined surface 531 . Therefore, when the mold device 100 is in a closed state, the position of the first slide core 311 can be finely adjusted in the X-axis direction, and the position of the second slide core 312 can be finely adjusted in the Y-axis direction. can be adjusted

The position of the first part 311a and the second part 311b of the first slide core 311 may be individually adjusted with respect to the injection product P due to the nature of the elastic material. In one embodiment, referring to FIG. 5C , the first part 311a of the first slide core 311 moves in the Z-axis direction when the positioning unit 520 of the positioning member 500 moves in the Z-axis direction with reference to FIG. 4 . Accordingly, the position of the first portion 311a may be adjusted by moving the locking block 510 in the X-axis direction with reference to FIG. 5C. In addition, the second part (311b) of the first slide core 311 is the locking block 510 as the position adjustment unit 520 of the position adjustment member 500 moves in the Z-axis direction with reference to FIG. The position of the second part 311b may be adjusted by moving in the X-axis direction based on 5c.

For example, as described above, the fixing unit 522 of the positioning member 500 may be connected to the auxiliary block 521 to move the auxiliary block 521 in the Z-axis direction with reference to FIG. 4 . Accordingly, the locking block 510 connected to the auxiliary block 521 may advance or retreat with respect to the injection product P. When the mold apparatus 100 is closed, the positions of the locking blocks 510 that come into close contact with the first part 311a and the second part 311b of the first slide core 311 may be individually adjusted.
