The other end of bar stretches into piston cylinder, and the one end of the mandril stretched into piston cylinder is connected by the inside of spring and piston cylinder
It connects, the spring is in compressive state；
The top plate is equipped with equal with telescopic unit quantity and one-to-one circular hole, and the mandril is located at outside piston cylinder
One end connect with pressure pad across circular hole.
Preferably, the length of the mandril for the telescopic unit being located in the middle part of sleeve is more than positioned at the flexible of sleeve inner edge
The length of the mandril of unit.
Preferably, being equipped with cylindrical cavity in the piston cylinder, the spring is located in cavity, empty in the piston cylinder
The depth of chamber is equal to the length of mandril.
The utility model has the beneficial effects that the gradual mold for automotive trim production of the utility model, structure
Simply, ingenious in design, it, can be from middle part to the gradual force in both sides, so that the injustice in somewhere can be this in molding

Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figs. 1-3, a kind of gradual mold for automotive trim production, including upper mold 1, lower die 2 and setting exist
Punching mechanism in upper mold 1, the upper mold 1 are arranged in the surface of lower die 2, and the punching mechanism is arranged in the lower section of upper mold 1；
The punching mechanism includes sleeve 3, pressure pad 4, top plate 8 and several telescopic units, and the sleeve 3 is vertically arranged
Cylinder, the pressure pad 4 are cambered surface, and the periphery of the pressure pad 4 is seamlessly connected with the lower edge of sleeve 3, in the pressure pad 4
The level height in portion is less than the minimum level height of sleeve 3, and the top plate 8 is circular slab, and the top plate 8 is arranged in sleeve 3
Lower end, between pressure pad 4 and sleeve 3, each telescopic unit is arranged in sleeve 3 top plate 8 laterally side by side；
The telescopic unit includes mandril 5, spring 7 and piston cylinder 6, and one end of the mandril 5 is located at outside piston cylinder 6,
The other end of the mandril 5 stretches into piston cylinder 6, and the one end of the mandril 5 stretched into piston cylinder 6 passes through spring 7 and piston
The inside connection of cylinder 6, the spring 7 are in compressive state；
The top plate 8 is equipped with equal with telescopic unit quantity and one-to-one circular hole, and the mandril 5 is located at piston cylinder
One end outside 6 is connect across circular hole with pressure pad 4.
Preferably, the length positioned at the mandril 5 of the telescopic unit at 3 middle part of sleeve is more than positioned at 3 internal edge of sleeve
The length of the mandril 5 of telescopic unit.
Preferably, being equipped with cylindrical cavity in the piston cylinder 6, the spring 7 is located in cavity, the piston cylinder 6
The depth of internal cavity is equal to the length of mandril 5.
In molding, pressure containing part is located in lower die 2, due to 5 longest of mandril of the telescopic unit positioned at the middle part of sleeve 3,
So the middle part of existing pressure pad 4 contacts lower die 2, the mandril 5 of stress first can be then retracted into piston cylinder 6, as upper mold 1 is under
The distance of mould 2 it is close, the pressure pad 4 of both sides also can be gradually pressed in lower die 2, until all mandrils 5 bounce back to piston cylinder 6
It is interior, at this point, be then to act directly on lower die 2 by pressure pad 4 by top plate 8, and before this process, the compression that is located in lower die 2
The part stress by middle part before this, then gradually extends into both ends, this process can smooth some injustice, to make
More soft pressure containing part be bonded more preferably with lower die 2, in this way by 8 big plane of top plate force, can or can not generate fold or
Person flattens some protrusions, to influence the compact dimensions of pressure containing part.
Compared with prior art, the gradual mold for automotive trim production of the utility model, simple in structure, design
It is ingenious, it, can be from middle part to the gradual force in both sides, so that the injustice in somewhere can be in this force mechanism in molding
Under, it is gradually smoothed, to keep original dimensional accuracy.
