Spring 19 can be compressed by the thrust of corresponding slide bar 18, store elastic potential energy, and two the second fixed plates 20 are located remotely from each other
During, angle becomes larger between two the second connecting rods 21, drives third fixed plate 22 to move upwards, third fixed plate
22 stretchy cutting plates 10 move upwards, after closure plate 7 is without the pressure of cutting plate 10, under the action of the first spring 8, and movable plate
6 meeting upward sliding a small distance, after movable plate 6 is in contact with two the first limited posts, the top of closure plate 7 can then connect with material feeding
After the bottom interior wall flush of mouth 2, upper mold 30 and lower die 1 are completely integrated, then the second circle can be brought down completely to by limiting plectane 13
In shape slot 23, and the top of plectane 13 and the top flush of lower die 1 are limited, at this time the bottom of cutting plate 10 and material feeding interface 2
Top inner wall flush EVA material is then injected by injection flow passage 29 at this point, material feeding interface 2 is then blocked without cutting plate 10
Liquid, feed liquid can be successively injected into the die cavity between upper mold 30 and lower die 1 through injection flow passage 29 and material feeding interface 2, to product at
After type, when opening upper mold 30, the push rod 13 after losing 30 gravity of upper mold can move upwards under the action of third spring 27, together
When, the second spring 19 in two the first circular troughs 17 will push two the second fixed plates 20 and move toward one another, two second connections
Bar 21 will push the downward telemechanical of third fixed plate 22, and third fixed plate 22 will push the downward telemechanical of cutting plate 10, when the first fixed plate
15 move up to when being in contact with the second limited post, and the bottom of cutting plate 10 can then drop to initial position, in material feeding interface 2
Molding material is then being chopped off.
