Claims

[Claims for Utility Model Registration] 1. A resin molded product obtained by injection molding, which has a plurality of pockets arranged regularly and at intervals, and which are formed so as to connect the pockets and intersect with each other. 1. A resin injection molded product having structural ribs, the part of the molded product corresponding to the intersection of the structural ribs serving as a gate during injection molding. 2. A resin molded article 10 obtained by injection molding, on the surface of which a plurality of pockets 12 are regularly arranged at intervals and are recessed from a reference plane 11, On the back surface, a depression 14 is formed between the pockets, and inside the depression, a structural rib 17 is formed that connects the pockets and intersects each other, and the intersection part 1 of the structural rib is formed.
A resin injection molded product having structural ribs, characterized in that the front or back surface of the molded product corresponding to No. 9 is used as a gate 2 during injection molding. 3 The pockets 12 are rectangular and arranged in a grid pattern,
3. The resin injection molded product according to claim 2, wherein the structural ribs 17 connect the diagonally arranged pockets. 4. A resin molded article 20 obtained by injection molding, on the surface of which a plurality of protrusions 23 are regularly arranged at intervals and protrude from a reference plane 21. At the same time, a pocket 22 recessed toward the reference plane side is formed in the raised part, and structural ribs 27 are formed on the reference plane of the same surface to connect the raised parts and intersect with each other. A resin injection molded product having structural ribs, characterized in that the front or back surface of the corresponding molded product is used as a gate 2 during injection molding. 5. The resin injection molded product according to claim 4, wherein the raised parts 23 forming the pockets 22 are rectangular and arranged in a grid pattern, and the structural ribs 27 connect the raised parts arranged diagonally.
