Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a plastic mold for one-piece molded plastic boxes. Background Technology

[0002] As living standards rise, various household tools have become "necessities," indispensable to people, such as brooms, mops, and washbasins—essential items in every home. Among these, plastic boxes are also a very important household tool.

[0003] However, in the processing of plastic boxes, gaps are very likely to appear at the mold opening and connection points of the existing technology, which will cause material to overflow and thus result in certain cost losses. Moreover, most molds are single molding and cannot be processed in multiple ways, which makes them somewhat inefficient.

[0004] Therefore, a plastic mold for a one-piece molded plastic box is provided to solve the above problems. Utility Model Content

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figures 1 to 4 As shown, the plastic mold for the one-piece molded plastic box of this utility model includes a box body 1. A snap-fit ​​component 2 is fixedly connected to the middle of one side surface of the box body 1, and a limiting component 3 is fixedly connected to the middle of the other side surface of the box body 1. The limiting component 3 is adapted to the snap-fit ​​component 2. Combination grooves 4 are provided on both sides of the upper surface of the box body 1. A connecting rod 5 is fixedly connected to the inner bottom wall of the combination groove 4. A connecting groove 7 is provided at the bottom of the two inner side walls of the box body 1. A box cover 8 is provided on the upper surface of the box body 1. In actual implementation, multiple molds can be injection molded simultaneously, and the mold opening connection is made tighter. Specifically... By evacuating the U-shaped channel through the valve, a negative pressure state is created between the lid and the box body, which effectively ensures the airtightness of the box body 1 and the lid 8. Then, the operator connects multiple box bodies 1 by using the snap-fit ​​parts and limiting parts 3 between them. Finally, the snap-fit ​​parts 2 and limiting parts 3 on the finishing box body 1 slide to snap-fit ​​the sleeve plate 15 and the partition plate 14, thereby sealing the box body 1. Compared with the existing technology, the plastic mold of this one-piece molded plastic box can perform injection molding operations on multiple molds at the same time, and the mold opening connection is tighter.

[0025] A protrusion 9 is fixedly connected to the middle of the lower surface of the lid 8. A groove is provided at the edge of the protrusion 9 in the middle of the lower surface of the box body 8. There are four connecting rods 5. The four connecting rods 5 are divided into two groups. Each group of connecting rods 5 has a U-shaped through groove 6. In actual implementation, the air between the box body 1 and the lid 8 can be extracted through the U-shaped through groove 6, so that a negative pressure state appears between the lid 8 and the box body 1.

[0026] Both sides of the lower surface of the cover 8 are fixedly connected with sleeves 10 that are compatible with the connecting rod 5. Both sides of the upper surface of the cover 8 are provided with air inlets 11, which are connected to the sleeves 10. In actual implementation, the staff can clean the air inlets 1 to avoid blockage, and can quickly replace the valve 11 when it is damaged.

[0027] An air valve 12 is fixedly installed on the air inlet 11. Injection pipes 13 are provided on both sides of the upper surface of the box cover 8. A partition 14 is slidably engaged on one side of the snap-fit ​​2, and a sleeve 15 is slidably engaged on one side of the limiting member 3. In actual implementation, the staff can engage the partition 14 and the sleeve 15 on the snap-fit ​​2 and the limiting member 3 on the first and last box bodies 1, so that a set of box bodies 1 can be effectively sealed.

[0028] The top of both sides of the box body 1 is provided with a horizontal plate 16, which is fixed by a pin. The middle of both sides of the box cover 8 is provided with a snap-fit ​​plate 17, which is fixed by a pin. The middle of the upper surface of the two horizontal plates 16 is fixedly connected with an installation part 18. In actual implementation, the installation part and the horizontal plate 16 can effectively restrict the movement trajectory of the snap-fit ​​plate 17 to ensure the removal of the box cover 8. The horizontal plate 16 and the snap-fit ​​plate 17 can be disassembled by inserting and pulling the pin, thus facilitating the removal of the box cover 8.

[0029] Mounting component 18 slides and engages with mounting plate 17. Threaded component 19 is threaded through the middle of the upper surface of mounting component 18. The bottom of threaded component 19 is movably engaged with lid 8. In actual implementation, the operator can rotate threaded component 19 to continuously separate lid 8 from box body 1 after degassing, thus effectively ensuring the rapid removal of lid 8.
