Preceding sealing overhead door 141, rear sealing overhead door 143 are adjacent to the lateral wall at vacuum foam mould station, and foam chamber 9 is made to be in seal shape
State；Then molding pressurizing cylinder 138 molds lower die 32, middle mould 33 and upper mold 31, and pressurizes, every time when molding, die sinking
By in mold indentation sealing steel bushing 194, spring 193 is compressed the screw rod 191 of auxiliary device；
The middle mould feed device and lower die feed device of automatic material weighing racking machine are respectively to different colours (same color can also)
EVA particulate material weigh feeding into vacuum foam mould station, and middle mould feed device and lower die feed device are by respective
Feed hopper be fed to vibration bucket, the vibrator coil 24d in vibration bucket is cycled on, power-off is so that vibrator coil 24d and armature
Pulse attraction between 24e generates, disappears, and then promotes chute feeder 24b to move back and forth to realize symmetrical feeding funnel
Feeding；After claiming feeding funnel metering, when claiming the raw material in feeding funnel to reach setting value, vibration bucket stops feeding, claims under feeding funnel
Bin gate is opened, and the raw material in bucket is knocked down in device for discharging, then put raw material in lower hopper by device for discharging, when lower hopper
After wherein row bucket fills, middle mould feed device pulls lower hopper to move ahead by transposition cylinder, and heel row bucket is allowed to continue splicing；
It is opened after mold reaches preheating temperature, separates upper mold 31, middle mould 33, lower die 32, middle mould 33 is in chaindriven pulling
Under move to 246 lower section of middle mould lower hopper, at this time in 247 piston rod of mould blowing cylinder stretch out, middle mould blowing supporting plate 248 is drawn
It opens, falls into the raw material in middle mould lower hopper 246 in middle mould 33；32 feed device of lower die is then by toothed belt conveying device
259 pull lower die lower hopper 256 to move ahead, and allow heel row bucket to continue splicing, toothed belt conveying device 259 pulls on down after having connect material
Mould lower hopper 256 moves to the top of lower die 32, and 257 piston rod of lower die blowing cylinder stretches out at this time, by lower die blowing supporting plate 258
It pulls open, falls into the raw material in lower die lower hopper 256 in lower die；

Tightly, and then before driving overhead door 141, the rear lateral wall for sealing overhead door 143 and being adjacent to vacuum foam mould station are sealed, foam chamber 9 is made
It is again at sealing state, vacuum pump 4 operates at this time, will be evacuated in foam chamber 9 by extraction valve 18, while molding pressurization
Oil cylinder 138 molds lower die 32, middle mould 33 and upper mold 31, and pressurizes, raw material heated vulcanization in mold, heating vulcanization
When time closes to an end, at this point, inflating when inner and outer air pressure is constant in foam chamber 9 by intake valve 17, cylinder 156 is tensed again
Lifting sliding slot 158 is unclamped, preceding sealing overhead door 141, rear sealing overhead door 143 are under the pulling of lifting cylinder 144, along liter
158 downlink of sliding slot drops, molding 138 piston rod of pressurizing cylinder is withdrawn, lower die 32 and upper mold 31 molding pressurizing cylinder 138 with separate
Quickly separated under the driving of die sinking auxiliary cylinder 139, meanwhile, the spring 193 for being opened auxiliary device resets rapidly, promotes middle mould 33
It is separated with upper mold 31；The sulfide of two kinds of colors after heating vulcanization is attached to respectively in lower die 32 and upper mold 31；Then, middle mould 33
Prepare the splicing of a new round in moving under chaindriven pulling below the middle mould lower hopper 246 of mould feed device；It is true at this time
Preceding sealing overhead door 141, rear sealing overhead door 143 in empty foaming mould station rise and tense again, make foam chamber is previous to be in
Sealing state, meanwhile, foam chamber 9 is evacuated by vacuum pump 4 again, and it then molds 138 piston rod of pressurizing cylinder and rises again,
Lower die 32 and upper mold 31 are pressed, the raw material after making upper and lower two kinds of vulcanizations fits into heating foaming stages；When heating foaming
Between when reaching, inflated in foam chamber 9 by intake valve 17, when inner and outer air pressure is constant, tenses cylinder 156 and again slide lifting
Slot 158 unclamps, and preceding sealing overhead door 141, rear sealing overhead door 143 are under the pulling of lifting cylinder 144, along lifting sliding slot
158 downlinks.At this point, product is molded, lower die 32 is quickly opened under the quickly driving of die sinking auxiliary cylinder 139, obtains nothing
Turn to be yellow, burn, stomata, deformation the defects of high quality of products (such as Figure 15).
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
