Technical Field
[0001] The invention relates to the technical field of sole production, in particular to a production process of anti-fouling and wear-resistant popcorn soles. Background Art
[0002] The existing forming process of popcorn soles is to close the upper mold and the lower mold, after which the material flows from the upper mold into the mold cavity, and then the popcorn sole is formed under a certain temperature and a certain pressure. This kind of popcorn sole has the advantages of light weight and good elasticity and is widely used in sports shoes. However, popcorn soles are not resistant to dirt, and are difficult to clean after being dirty, and cannot be worn for a long time. In order to overcome this problem, a kind of anti-fouling popcorn sole with a layer of film covered on the outer surface of the popcorn sole has appeared on the market, such as the Chinese invention patent publication number CN119348060A, which is a film-coating integrated molding machine and molding process suitable for popcorn soles. The process is: S1. The output roller and the recovery roller cooperate to convey the film material so that the film material is between the concave mold and the convex mold and the projection of the film material toward the concave mold covers the cavity, and the film material stops conveying; S2. The first bracket and the second bracket move closer to each other until the convex mold is close to the mold. The steam generator introduces steam into the steam chamber of the punch, and the steam is blown toward the film material through the corresponding second air hole, and the film material is softened by heat; S3. The positive and negative pressure generator draws air into the air pressure chamber of the die to make the air pressure chamber into a negative pressure state, and the first air hole generates negative pressure suction, and the film material is sucked into the cavity. Since the film material softens by heat and has ductility, the film material sucked into the cavity is deformed and evenly adheres to the inner wall of the cavity; S4. The first bracket moves closer to the second bracket until the punch closes the cavity, and injects into the cavity through the injection port. and fill popcorn grains; the steam generator passes steam into the steam chamber of the punch, the steam enters the cavity through the second air hole corresponding to the steam chamber, and then is discharged from the second air hole corresponding to the exhaust chamber, the passing steam heats the popcorn grains and makes their surface sticky; S5. The first bracket and the second bracket move closer to each other until the punch and the die are combined and pressed tightly. During this process, the cutter is placed in the cutting groove to cut the film material, and the film material in the cavity is cut independently; the insert is pressed toward the cavity, and the popcorn grains are squeezed The first bracket and the second bracket are separated and moved to form a sole blank, and the film material is bonded and covered on the bottom and side of the sole blank; S6. The first bracket and the second bracket are separated and moved until there is a discharge gap between the male mold and the female mold, and the positive and negative pressure generators are introduced into the air pressure chamber. The first air hole generates a thrust to push the sole blank out of the cavity, and the sole blank falls out through the discharge gap; S7. The output roller and the recovery roller rotate in coordination, and the cut part of the film material is rolled into the recovery roller, and the step 1 is returned to the next round to repeat the sole molding process. However, in this molding process, the online cutting of the film prolongs the entire injection molding process, which is time-consuming and reduces the molding efficiency. In addition, the online cutting operation of the film can only use ordinary non-sticky films, which makes the film easy to detach from the sole after molding. At the same time, the online cutting operation will cause a large change in the entire injection mold, which can only be used for the molding of popcorn soles with films, and cannot be used for the molding of popcorn soles without films, and has low versatility.

A vacuum exhaust pipe 6 connected to the vacuum chamber is installed on the outer wall of the lower die 12. In this way, the entire die can be transferred to the vacuum machine by means of the vacuum exhaust pipe 6 to evacuate the vacuum exhaust pipe 6. At this time, the easy-to-wipe light-transmitting protective film and the lower die 12 form a sealed chamber. In this way, each suction hole evacuates the chamber, and the easy-to-wipe light-transmitting protective film is folded downward by the suction force of each suction hole and adheres to the lower cavity 200 of the lower die 12. After the vacuuming is completed, the entire die is transferred to the molding machine for molding.
[0027] In the present invention, in the above-mentioned film suction step, the concave mold can be vacuumed in the lower mold frame, that is, an air suction channel whose upper end is connected to the air suction hole and the lower end is directly connected to the outside of the bottom plate is provided in the lower mold 12 corresponding to each air suction hole, and the lower mold frame is provided with a placement platform for the concave mold to be placed on and is located above the bottom surface of the lower mold frame, this placement platform is a placement plate, the placement platform and the side wall of the lower mold frame have an air flow channel, and the placement platform is located within the range of the lower cavity and has a through hole, that is, the lower mold frame is provided with a partition that divides the lower mold frame into two upper and lower chambers, this partition is the placement platform, and at least one of the four sides of the partition does not contact the inner side wall of the lower mold frame, and has a spacing, this spacing is the air flow channel, and the partition is located at the lower concave mold 12 and is connected to a chamber below. Square through hole, this square through hole is the through hole; when used, after the film placing step is completed, the die is placed on the placing platform, and then the upper mold frame moves down and closes with the lower mold frame, and the upper mold frame and the lower mold frame are closed to form a vacuum chamber, and a vacuum treatment is performed before the molding process step is started. At this time, the die in the vacuum chamber is correspondingly vacuumed, and the vacuum gas passes through the air flow channel, the through hole, the suction channel and the suction hole in turn to the lower cavity, and the lower cavity is vacuumed. At this time, the easy-to-wipe translucent protective film in the lower die 12 is folded downward by the vacuum suction force and adheres to the lower cavity 200 of the lower die 12, realizing the film suction operation in the molding machine. This operation can omit the setting of the vacuum machine, and the film suction operation only takes 5-10 seconds, which will not take up too much time, so it will not affect the molding efficiency.
