[0027] In this embodiment, during the injection molding process, the lower injection mold 1 and the upper injection mold 2 are brought close to each other so that the storage box molding cavity 4 and the storage box molding protrusion 5 are abutted and matched to form a complete cavity, and the molten material is injected through the injection molded part 3. During molding, the first storage box side groove molding part 6 and the second storage box side groove molding part 7 are matched to synchronously mold the groove structure on both sides of the storage box plastic part. No secondary processing is required. After the injection molding is completed, the mold is opened, and the second storage box side groove molding part 7 is slid away from the first storage box side groove molding part 6 by moving the sliding ejection component 8 to complete the internal demolding. Then the first storage box side groove molding part 6 is moved away from the storage box molding protrusion 5 to avoid damage to the groove structure on both sides of the storage box plastic part during demolding, thereby ensuring the overall strength of the plastic part, facilitating the subsequent removal of the plastic part, and having strong practicality.

[0031] In this embodiment, after the injection molding is completed, the mold is opened, and the horizontal sliding table 12 is moved. At this time, the limiting inclined rail 13 and the first limiting groove 14 are slidably matched, driving the sliding rail seat 9 to slide obliquely inward, through the sliding cooperation between the inclined connecting rail 10 and the second storage box side groove molding part 7.

[0032] The second storage box side groove forming part 7 includes an inner auxiliary molding slider 15 disposed in the lower injection mold 1 . The inner auxiliary molding slider 15 has an inner protrusion 16 . The inner auxiliary molding slider 15 is disposed opposite to the first storage box side groove forming part 6 .

[0033] In this embodiment, during injection molding, the inner protrusion 16 on the inner auxiliary molding slider 15 is used to assist in molding the side groove structure of the plastic part. After injection molding is completed, the inner protrusion 16 is separated from the molded side groove structure to achieve internal demoulding.

[0034] Combination Figure 3-4 As shown, a second limiting groove 166 is provided in the inner auxiliary forming slide block 15 , and the inclined connecting rail 10 is slidably matched with the second limiting groove 166 .

[0035] In this embodiment, internal demoulding is achieved through the sliding cooperation between the inclined connecting rail 10 and the second limiting groove 166, and the sliding stroke is limited at the same time.

[0036] The first storage box side groove forming member 6 includes an outer auxiliary forming slider 17 disposed in the lower injection mold 1 . The outer auxiliary forming slider 17 has an outer protrusion 18 . The outer protrusion 18 is disposed opposite to the inner protrusion 16 .
