As shown in fig. 1-8, the embodiment of the present application provides a secondary cutting structure applied to an edge trimming mold, the edge trimming mold comprises an upper mold 1 and a lower mold 2, the secondary cutting structure is mounted on two sides of the upper mold 1 and the lower mold 2, the two sides of the secondary cutting structure are symmetrically arranged, the structure on each side comprises a plurality of upper material blocking frames 7 mounted on the upper mold 1, an upper cutter 5, a polyurethane material pressing block 6, a material loading block 8, and a lower cutter 9 and a material unloading blocking frame 4 mounted on the lower mold 2,

the waste support 3 comprises a T-shaped support block and a first inclined rod, the upper end of the T-shaped support block is connected with the middle part of the first inclined rod, the first inclined rod is low in outside and high in inside, and one end of the outside is provided with a downward bend;

the upper material blocking frame 7 comprises a longitudinal connecting block, a second inclined rod and a first vertical rod, the lower end of the longitudinal connecting block is connected with the middle part of the second inclined rod, the second inclined rod is low outside and high inside, one end of the inner side of the second inclined rod is connected with the first vertical rod, and the lower end of the first vertical rod is provided with an outward bend;

the unloading keeps off frame 4 and includes end connecting block and Z type pole, end connecting block upper end is connected with Z type pole, go up cutter 5 and lower cutter 9 and cooperate the use, polyurethane presses material piece 6 to set up in the one side of last cutter 5, with the unloading keeps off the frame 4 and cooperatees the use.

The working principle is as follows:

(1) the mould is in the use, and the lower mould is closed, produces the waste material through the sword piece effect, and the waste material falls on waste material support 3, produces the trend of landing downwards from this, but goes up fender work or material rest 7 and blocks the waste material and prevent that the waste material from gliding. At the moment, the front end of the waste is loaded on the loading block 8 to prevent the waste from inclining and rotating, the rear end of the waste is blocked by the upper material blocking frame 7, and the waste is not moved at the moment and is in a static state.

(2) Open state of upper die 1: at the moment, the upper material blocking frame 7 moves upwards along with the upper die 1, the upper material blocking frame 7 loses the limiting effect on the waste materials, and the waste materials have a downward sliding tendency due to gravitational potential energy. Because the lower material blocking frame plays a limiting role at the front end, the whole section of waste material passes through the waste material bracket 3 and then slides to the lower cutter 9, and the waste material is fixed and is in a static state.

(3) The upper and lower dies 2 are closed again: the polyurethane material pressing block 6 firstly presses materials and presses on the lower cutter 9, the upper cutter 5 and the lower cutter 9 interact with each other to cut off the whole section of waste materials, and the work is finished.

The mechanism has the characteristics of simple and clear structure, simplicity in debugging, capability of saving the design cost of the die, easiness in later-stage maintenance and the like, and can effectively avoid the cutting problem of secondary shearing of the waste material knife and the problem of difficulty in field debugging.

The technical means not described in detail in the present application are known techniques.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
