- the circumferential surface of 5 has a V-groove cross-section, and the recess 4 is formed when the resin material is injected.
- the gate portion 5 is, for example, a square of 2 mm X 2 mm, and the depth of the V-groove serving as the guiding portion 4 is 0, so that the dimension of the molding portion of the gate portion 5 is 0.3 mm.
- the cross-sectional shape is set to 2 to 0.3 mm and the cutting angle is set to 45 °.
- the gate portion 5 is formed in the gate portion 5 of the resin molded product 1 after being molded by the metal mold.
- the cutting edge of the cutting tool can be guided to the cut portion of the gate part 5 by the guiding part 4 and can be easily positioned. 5 can be stably cut at a certain point, and the cut surface also has a good finished surface, which has the effect of improving the finishing accuracy of the resin molded product 1.
- the gate remaining portion 5 for each resin molded product 1 is constant, so that the gate relief dimension at the time of resin molding can be determined quantitatively. There is no need to consider this.
- FIG. 3 (A) shows a gate-processed molded product according to Embodiment 2 of the present invention as a runner 6 and a gate portion.
- FIG. 3 (B) is a perspective view of the gate portion 5 in FIG. 3 (A).
- the guiding portion 4 is formed in contact with the gate portion 5 of the resin molded product 1 as much as possible in contact with the resin molded product 1.
- a one-sided vertical groove-shaped guiding portion inclined in a taper shape toward the side surface between the gate portion 5 and the vertical side surface of the resin molded product 1. 4 is formed.
- the concave portion (gate relief) 2 in the first embodiment is not required, and the gate remaining portion 3 can be significantly shortened. If a plurality of resin moldings 1 are stacked and fixed so that the lead-in part 4 of the gate part 5 is aligned in a straight line, each gate part 5 of the resin moldings 1 can be cut simultaneously. There is an effect of becoming. It is also possible to freely adjust the length of the remaining gate part 3. By adjusting the length of the remaining gate part 3, it is possible to eliminate the blurring of the resin molded product 1 (attaching the resin molded product 1) There is an effect that it can also be used as a projection for preventing erroneous insertion when inserted into a member.
- FIG. 4 is a perspective view showing a gate processing molded product according to Embodiment 3 of the present invention.
- the resin molded product 1 according to the third embodiment is formed as a button for switch operation, and is obtained by substituting the remaining gate portion 3 as a convex portion for removing the blur provided on the button, and its sectional shape.
- the (cut) is rectangular or trapezoidal. According to the third embodiment configured as described above, there is an effect that the gate portion 5 of the resin molded product 1 can be used as a blur removal of the resin molded product 1.
- FIG. 5 is a perspective view showing the remaining gate part of the gate processing molded product according to the fourth embodiment of the present invention.
- the gate portion 5 of the resin molded product 1 in each of the above embodiments is formed into a cylindrical shape, and the circumferential surface of the gate portion 5 has a V-shaped cross section, and the recessed portion 4 has a circumferential shape. It is configured to be formed in a direction.
- the same effects as those of the respective embodiments can be obtained.
- FIG. 6 is a perspective view showing the remaining gate part of the gate processing molded product according to the fifth embodiment of the present invention.
