Specific embodiment
As shown in Figure 1 to Figure 3, a kind of soundproof mat for engine hood hot pressing die cutting die, including upper die holder 1 and lower die holder 2, upper mold
1 top of seat is connected with press machine, and molding steel plate 3 is equipped on the downside of upper die holder 1, and the middle section of molding steel plate 3 is embedded with punch-pin 31,
The top plate 32 for being surrounded by protrusion of punch-pin 31, the thickness of top plate 32 are slightly larger than the thickness in the thickness of punch-pin 31, therebetween
Thickness difference be equal to soundproof mat for engine hood to be processed thickness；Lower die holder 2 is fixedly arranged above multiple spring bases 7, on spring base 7
Side is equipped with liftable movable plate 4, and movable plate 4 is horizontally disposed, and top plate 32 can be pressed downward movable plate 4, and lower die holder 2 is equipped with one
With the matched cavity plate 5 of punch-pin 31, the intermediate position of movable plate 4 is equipped with the matched die hole of shape with cavity plate 5, the upside of cavity plate 5
It is set in die hole, die hole can be moved down relative to cavity plate 5, to make cavity plate 5 protrude from the upper surface of movable plate 4, in turn
It is molded with punch-pin 31 and carries out hot press working；It is designed with electric heater unit 6 in punch-pin 31 and cavity plate 5, for forming to hot pressing workpieces；
The top of cavity plate 5 is surrounded by cutting blade 51, for being punched the workpiece after hot pressing.
Preferably, as shown in figures 1 and 3, the limiting slot 41 of multiple levels is equipped in movable plate 4, multiple limiting slots 41 divide
It is not symmetrically distributed in the side of 4 surrounding of movable plate, horizontal limited support 42 is equipped in limiting slot 41, limited support 42
Short transverse is fixed setting, and limiting slot 41 can be moved up and down relative to limited support 42, and top plate 32, which pushes movable plate 4, makes punch-pin
31 with cavity plate 5 mold when, limited support 42 just resists the top of limiting slot 41, thus limit top plate 32 continue push movable plate
4, at this point, punch-pin 31 and cavity plate 5 can within the set time heat workpiece pressure maintaining, it is conducive to hot-forming；Limited support 42
