FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the vent of the present invention;
figure 3 is a schematic view of the structure of the vent sheet of the present invention.
In the figure: 1. the device comprises a movable die, a fixed die, a top die, a fixing bolt, a guide pillar, a guide sleeve, a guide pin 7, a die cavity, a guide pin 8, a ventilation piece 9, a ventilation sheet, a ventilation channel 10 and an exhaust channel.
[ detailed description ] embodiments
A precision press mold having a vent structure according to the present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a precision stamping die with exhaust structure, is including setting up cover half 2 at movable mould 1 lower extreme, and die cavity 7 has been seted up to the upper surface of cover half 2, and ventilation piece 8 has been seted up to cover half 2 inner wall, and ventilation piece 8 is including seting up the piece 9 of ventilating that sets up in exhaust passage 10 and the exhaust passage 10 of die cavity 7 lateral wall, and the other end of exhaust passage 10 runs through cover half 2 outer wall.
The surface of one side of the ventilation sheet 9 and the side wall of the die cavity 7 are in the same vertical plane, the ventilation sheet 9 is made of rubber, and the center of the ventilation sheet 9 transversely penetrates through a slit groove with a cross structure, so that compressed air can be conveniently discharged through air pressure expansion when ventilation is needed.
