Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
Referring to figure, the present invention provides a kind of technical scheme: a kind of EPP forming machine, including frame 1, die 2, punch 3 and
Press moulding mechanism 4, punch 3 is laterally opposed with die 2, between punch 3 with die 2 relative to face be respective front, punch 3 is with recessed
Face opposing between mould 2 is the respective back side, and punch 3 is respectively provided with projection and groove with the front of die 2, protruding and groove
Shape adapts with the shape of EPP foam plate to be formed.The back side of die 2 connects pull bar, and die 2 is by the fixing peace of pull bar
It is contained in frame 1.Press moulding mechanism 4 acts on the back side of punch 3, makes punch 3 move relative to die 2, and press moulding mechanism 4 can be
Hydraulic cylinder or ball-screw isoline output mechanism.
The process of EPP foam sheet metal forming is: first, press moulding mechanism 4 drive punch 3 make its 2-in-1 with die together with i.e. close
Mould, forms the molding space of EPP foam plate between punch 3 and die 2, then vacuum pump is by being connected to the connection on die 2
Pipe is to molding space evacuation, and then, the EPP beadlet after foaming is sprayed in molding space by the spray gun on die 2, then heats
Die 2 and punch 3 are heated by device, and the beadlet in molding space forms EPP foam plate under pressure and heat effect,
After by condenser, the EPP foam plate of high temperature is cooled down, punch 3 press moulding mechanism 4 act under leave die 2, EPP foam plate
Then stay in the groove of die 2.
In order to quickly taken out in die 2 by the EPP foam plate after molding, the bottom land of die 2 has counter sink, heavy
Head bore is macropore and aperture by the bottom land of die inner groovy to the die back side successively, say, that be that the macropore of counter sink is near recessed
The bottom land of mould 2, the aperture of counter sink, near the back side of die 2, also includes that shedding mechanism 5, shedding mechanism 5 include push pedal 51, push away
Bar 52 and driving member 53, push pedal 51 is positioned at the macropore of counter sink, and the front of push pedal 51 flushes with the bottom land of die, push rod 52
One end is connected to the other end on push pedal 51 back side and passes the aperture of counter sink and extend to outside die 2, push pedal 51 and push rod 52 points
Not and being slidably matched between the macropore of counter sink and aperture, driving member 53 can promote push rod 52 to make push pedal 51 by the bubble in die 2
Foam plate is pushed out to outside die 2.After EPP foam sheet metal forming, driving member 53 drives push rod 52 to push pedal 51 direction i.e. EPP foam
Direction, plate place is moved, push pedal 51 EPP foam plate is applied thrust, so that EPP foam plate quickly leaves die 2, carry
High production efficiency.
Driving member 53 can make cylinder etc., and the driving member in the present invention includes cam 531 and runner 532, and runner 532 can turn
The dynamic push rod 52 that is arranged on is positioned on the one end outside die 2, and cam 531 is driven eccentric rotary, cam 531 to rotate a circle by motor
Cam 531 can be driven to move once to direction, push pedal 51 place.When the arc department that the radius of gyration on cam 531 changes from small to big by
When gradually contacting with runner 532, runner 532 will move to direction, EPP foam plate place together with push rod 52 and push pedal 51, thus
Anyway EPP foam plate discharge process in die 2.
The big of counter sink is i.e. automatically returned in order to make push pedal 51 automatically reset after being released in die 2 by EPP foam plate
In hole, push rod 52 is provided with flange 521, and frame 1 is provided with fixed plate 11, fixed plate 11 be positioned at flange 521 and runner 532 it
Between, push rod 52 slidably through fixed plate 11, is connected between flange 521 and fixed plate and has the spring 6 being placed on outside push rod 52.When
When cam 531 drives runner 532 and push pedal 51 to move to EPP foam plate direction, spring 6 is compressed, and push pedal 51 is by EPP foam plate
After releasing in die, cam 531 gradually loses and the contacting of runner 532, push pedal 52 and push rod and runner under spring 6 acts on
Automatically reset.
The ultimate principle of the present invention and principal character and advantages of the present invention are more than shown and described, for this area skill
For art personnel, it is clear that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing substantially from the present invention spirit or
In the case of basic feature, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, all should be by
Embodiment regards exemplary as, and is nonrestrictive, the scope of the present invention by claims rather than on state
Bright restriction, it is intended that include all changes fallen in the implication of equivalency and scope of claim in the present invention
In.Should not be considered as limiting involved claim by any reference in claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
