Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a novel pressure-resistant and shock-proof combined EPP packaging box forming device. Background Art

[0002] EPP is the abbreviation of expanded polypropylene, which is the abbreviation of a new type of foam plastic. EPP is a polypropylene plastic foam material, which is a high-performance, highly crystalline polymer / gas composite material. With its unique performance, it has become the fastest growing new environmentally friendly pressure-resistant, buffering and heat-insulating material. EPP is also an environmentally friendly material that can be recycled and reused, can be naturally degraded, and will not cause white pollution.

[0003] When making EPP packaging boxes, most of the EPP materials are melted and then injected into the mold for extrusion molding. When most of the existing molds are in use, the upper mold generates a large impact force on the lower mold during extrusion. Long-term impact force can easily cause damage to the molding device and reduce the service life of the molding device. Therefore, we propose a new type of pressure-resistant and shock-proof combined EPP packaging box molding device. Utility Model Content

DETAILED DESCRIPTION

[0026] Example 1

[0027] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a new type of pressure-resistant and shock-proof combined EPP packaging box forming device, including a base 1, a support frame 2 is fixedly connected to the top of the base 1, a bottom mold 31 and a top mold 32 are arranged above the base 1, the top mold 32 is arranged above the bottom mold 31, an electric cylinder is fixedly connected to the top of the support frame 2, the output end of the electric cylinder is fixedly connected to the top of the top mold 32, the inner wall of the bottom mold 31 is fixedly connected to the inner mold 33, and the interior of the support frame 2 includes:

[0028] The buffer assembly 4 includes a bottom plate 41, which is arranged below the bottom mold 31, and the left and right sides of the top mold 32 are fixedly connected with connecting plates 42, and the top of the bottom plate 41 is fixedly connected with a buffer spring 43;

[0029] The shock absorbing assembly 5 is provided with a plurality of shock absorbing assemblies 5, and the plurality of shock absorbing assemblies 5 are all provided under the bottom plate 41. The shock absorbing assembly 5 comprises a shock absorbing shell 51, the inner wall of the shock absorbing shell 51 is slidably connected with a piston 52, a shock absorbing rod 53 is fixedly connected under the piston 52, a sealing sleeve 54 is sleeved on the rod wall of the shock absorbing rod 53, and a shock absorbing spring 55 is sleeved on the surface of the shock absorbing shell 51.

[0030] The top of the bottom plate 41 is fixedly connected to the bottom of the bottom mold 31, the upper end of the buffer spring 43 is fixedly connected to the bottom of the connecting plate 42, the upper end of the shock-absorbing shell 51 is fixedly connected to the bottom of the bottom plate 41, the lower end of the shock-absorbing rod 53 is fixedly connected to the top of the base 1, the upper and lower ends of the shock-absorbing spring 55 are respectively fixedly connected to the bottom of the bottom plate 41 and the top of the base 1, and the surface of the sealing sleeve 54 is fixedly connected to the inner wall of the shock-absorbing shell 51.

[0031] A first magnetic ring 56 is fixedly connected to the bottom of the shock-absorbing shell 51, and a second magnetic ring 57 is fixedly connected to the top of the base 1. The second magnetic ring 57 is sleeved on the rod wall of the shock-absorbing rod 53. The opposite sides of the first magnetic ring 56 and the second magnetic ring 57 have the same magnetic poles, and a buffer ring 58 is fixedly connected to the inner wall of the second magnetic ring 57.

[0032] Buffer openings 59 are provided on both the left and right sides of the shock-absorbing shell 51. The internal diameter of the buffer opening 59 is small in the middle and large at both ends. A non-return assembly 6 is provided inside the buffer opening 59. The non-return assembly 6 includes a ball plug 61. A pagoda spring 62 is fixedly connected to the left side of the ball plug 61. A bracket 63 is fixedly connected to the left side of the pagoda spring 62.

[0033] The surface of the bracket 63 is fixedly connected to the left side of the inner wall of the buffer opening 59 .

[0034] During use, the electric cylinder electric top mold 32 on the support frame 2 moves to the bottom mold 31. When the top mold 32 moves, it impacts the bottom mold 31 on the bottom plate 41. The connecting plate 42 on the top mold 32 and the bottom plate 41 on the bottom mold 31 buffer the bottom mold 31 and the top mold 32 through the buffer spring 43, thereby reducing the impact between the bottom mold 31 and the top mold 32.

[0035] When the bottom plate 41 on the bottom mold 31 is moved by the bottom mold 31, the shock absorbing assembly 5 under the bottom plate 41 absorbs the pressure of the bottom mold 31, and the piston 52 on the shock absorbing rod 53 moves in the shock absorbing shell 51. Under the action of the sealing sleeve 54, the sealing between the shock absorbing rod 53 and the shock absorbing shell 51 is increased. At the same time, the shock absorbing spring 55 enables the shock absorbing shell 51 and the shock absorbing rod 53 to be reset. After the shock absorbing shell 51 and the base 1 are close, the first magnetic ring 56 on the shock absorbing shell 51 and the second magnetic ring 57 on the base 1 repel each other to avoid the shock absorbing shell 51 from colliding with the base 1, and at the same time increase the buffering force between the shock absorbing shell 51 and the base 1. After the shock absorbing shell 51 and the buffer ring 58 on the base 1 come into contact, the protective effect of the shock absorbing shell 51 is increased.

[0036] When the piston 52 moves in the shock absorber shell 51, when the piston 52 moves upward, the ball plug 61 on the left moves to the left side of the buffer port 59, and the pagoda spring 62 is compressed. At this time, the air in the shock absorber shell 51 is discharged through the buffer port 59 on the left. When the piston 52 moves downward, the ball plug 61 on the right starts to move. At this time, the external air enters the shock absorber shell 51 through the buffer port 59.
