Description

Technical Field

[0001] The invention relates to the technical field of foam sole injection production, in particular to a foam sole molding injection mold molding device. Background Art

[0002] Foam soles have the advantages of light material, light wearing, soft and comfortable texture, but the disadvantage is poor anti-slip performance. Therefore, this type of soles usually have patterns on the bottom for anti-slip performance. Soles of this type of material are usually produced by injection molding equipment. Common injection molding equipment is mostly vertical, but due to the large production volume of soles and the slow production efficiency of vertical injection molding equipment, it is gradually replaced by wheel-type injection molding equipment; multiple injection molds are arranged on the wheel-type injection molding equipment, and the rotation of the wheel drives the multiple injection molds to rotate, so that the injection molds pass through the injection station, cooling station, mold opening station, material picking station and cleaning station in turn.

[0003] The injection mold is usually provided with a single or two cavities, and the raw materials in the cavity are squeezed by the upper mold and cooled to form. However, since the molded sole is sunken in the cavity, its bottom and side wall are not separated from the cavity, it is difficult to remove the sole. In order to solve this problem, some people use a left and right double-opening mold. When the mold is opened, the cavity moves left and right and separates from the sole. However, this mold has the problem of difficulty in automatically controlling the mold opening; in addition, the existing foam sole injection mold can only be used to produce soles with the same pattern. For soles with different anti-slip patterns, the cavity shape needs to be changed. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The foam sole molding injection mold molding equipment is provided with a linkage mold opening mechanism. After the injection molding cooling is completed, the top block is moved upward to apply an upward thrust to the connecting shaft. The upward movement of the connecting shaft drives the two folding rods to rotate around the first pin shaft. At the same time, the two folding rods push the two lower plates away from each other through the first pin shaft. The two lower plates drive the first side mold and the second side mold to move away from each other until the folding rod rotates to a horizontal state, so that the side wall and the bottom of the sole are separated from the upper cavity. While the folding rod rotates, the connecting rod is pushed upward through the hinge seat. The upper and lower ends of the connecting rod are respectively rotated relative to the second pin shaft and the third pin shaft, so that the connecting rod pushes the upper plate to move up through the second pin shaft, and the upper plate drives the top plate to flip upward relative to the first side mold and the second side mold, so that the upper surface of the sole is separated from the pressing mold, which is convenient for taking out the sole after mold opening, avoiding the problem of difficulty in taking out the sole in traditional molds, and the lower plate drives the first side mold and the second side mold to open the mold left and right while the upper plate drives the top plate to open the mold upward, so as to realize the linkage mold opening of the first side mold, the second side mold and the top plate.

[0019] 2. The foam sole molding injection mold molding equipment is provided with a flip seat. When it is used for the injection molding production of soles with different anti-slip patterns, the first side mold and the second side mold are flipped upward by pushing the first side mold and the second side mold. The first side mold and the second side mold drive the rotating column to flip upward through the connecting block, and the rotating column drives the movable column to flip upward around the fourth pin shaft in the movable groove until the first side mold and the second side mold are in an upright state. Then the first side mold and the second side mold are turned horizontally, and the connecting block drives the rotating column to rotate 180° relative to the movable column through the clamping column, and then the first side mold and the second side mold are flipped downward and reset. At this time, the positions of the first side mold and the second side mold are swapped, and the lower cavity is at the top to replace the upper cavity for injection molding production, so that the injection mold can be used for the injection molding production of foam soles with two different patterns.

[0020] 3. The foam sole molding injection mold molding equipment is provided with a locking mechanism and a slide groove. When the first side mold and the second side mold rotate left and right around the fifth pin shaft on the base, the slider and the locking block are stuck in the slide groove and slide. The locking block and the slide groove limit the first side mold and the second side mold from shaking up and down relative to the base. When it is necessary to flip the first side mold and the second side mold to switch the lower cavity for production, the locking block is pressed to push the locking block back into the rectangular groove, so that the first side mold and the second side mold are separated from the base, which is convenient for subsequent upward flipping. The locking mechanism is used to maintain the stability of the connection between the first side mold and the second side mold and the base during the injection molding process, and is used to guide the first side mold and the second side mold in the process of moving away from each other.

[0021] 4. The foam sole molding injection mold molding equipment is provided with a lower cavity and a water cooling pipe. During the injection molding process of the upper cavity, the lower cavity falls on the base and just covers the outside of the water cooling pipe. By introducing cooling water into the water cooling pipe, the cooling water flows from the middle of the first side mold and the second side mold to take away the heat during the injection molding process and accelerate the rapid cooling and molding of the insole.

[0037] The linkage mold opening mechanism 36 includes an upper plate 361, a lower plate 362 is arranged below the upper plate 361, screws 363 are arranged through the upper plate 361 and the lower plate 362, the number of screws 363 is several, and the top plate 34, the first side mold 32 and the front side wall of the second side mold 33 are provided with screw holes that match the outer diameter of the screws 363, the front side of the lower plate 362 is connected to the first pin shaft 364, the outer side of the first pin shaft 364 is sleeved with a folding rod 365, a torsion spring 366 is installed between the folding rod 365 and the first pin shaft 364, and when the connecting shaft 367 is lower than the lowest height of the lower plate 362, the torsion spring 366 is in a normal tension state, and the folding rod 365 is away from the first pin shaft 36 4 is penetrated by a connecting shaft 367, which extends from the front side after passing through two folding rods 365, so as to facilitate the top block 54 to push it upward. A hinge seat 368 is installed on the upper surface of the middle part of the folding rod 365, and a hinge groove is provided in the hinge seat 368. The bottom of the connecting rod 3610 is inserted into the hinge groove, and the hinge groove limits the rotation angle of the connecting rod 3610, so that when the folding rod 365 moves upward, the connecting rod 3610 is pushed to rotate to a vertical state.

[0047] The method of using the present embodiment is as follows: when the user actually uses the injection molding equipment to produce foam soles, the raw materials are first poured into the injection molding machine 4 for hot melting, the turntable 2 rotates to drive the multiple injection molds 3 to rotate, so that the injection molds 3 pass from the bottom of the injection molding machine 4, and the injection molding machine 4 adds raw materials into the injection port 324. During the rotation of the injection mold 3 with the turntable 2, cooling water is introduced into the water cooling pipe 312, so that the cooling water flows from the middle of the first side mold 32 and the second side mold 33, taking away the heat during the injection molding process, and accelerating the rapid cooling and molding of the insole. After the injection mold 3 moves to the material taking mechanism 5, the hydraulic telescopic rod 52 is extended through the fixed block 53 to push the top block 54 The top block 54 moves upward to exert an upward thrust on the connecting shaft 367. The connecting shaft 367 moves upward to push the two folding rods 365 to rotate around the first pin shaft 364. At the same time, the two folding rods 365 push the two lower plates 362 away from each other through the first pin shaft 364. The two lower plates 362 drive the first side mold 32 and the second side mold 33 to move away from each other. The first side mold 32 and the second side mold 33 rotate relative to the fifth pin shaft 379 through the connecting block 378. The bottom of the first side mold 32 and the second side mold 33 moves relative to the slider 3111 and the locking block 3113 through the sliding groove 323 until the folding rod 365 rotates to a horizontal state, so that the side wall and the bottom of the sole are separated from the upper cavity 321. As the folding rod 365 rotates, the connecting rod 3610 is pushed upward through the hinge seat 368. The upper and lower ends of the connecting rod 3610 rotate relative to the second pin shaft 369 and the third pin shaft 3611, respectively, so that the connecting rod 3610 pushes the upper plate 361 upward through the second pin shaft 369. The upper plate 361 drives the top plate 34 to flip upward relative to the first side mold 32 and the second side mold 33, so that the upper surface of the sole is separated from the pressing mold 341. Then, the electric push rod 58 is extended to push the clamping claw 511 to insert into the upper cavity 321. Then, the clamping motor 515 drives the second rotating shaft 514 to rotate, and the second rotating shaft 514 drives the second gear 513 to rotate. The second gear 513 drives the first gear 513 to rotate. 12 rotates, the first gear 512 drives the first rotating shaft 510 to rotate, the first rotating shaft 510 drives the two clamping claws 511 to approach each other, clamp the sole in the upper cavity 321, and cooperate with the electric push rod 58 to contract to pull the sole out of the upper cavity 321, then the material taking motor 57 drives the middle shaft 55 to rotate 180 degrees, the middle shaft 55 drives the electric push rod 58 to turn, and cooperate with the clamping claw 511 to loosen and the sole falls to be collected, after the sole is taken out, the hydraulic telescopic rod 52 contracts to drive the top block 54 to move downward, the rebound force generated by the torsion spring 366 drives the folding rod 365 and the connecting rod 3610 to reset, the first side mold 32 and the second side mold 33 approach each other, and the top plate 34 is reset;When used for the injection molding production of soles with different anti-slip patterns, the screws 363 are loosened to temporarily disassemble the upper plate 361 and the lower plate 362, and then the top plate 34 is flipped up, and then the locking block 3113 is pressed to push the locking block 3113 back into the rectangular groove 3112, and the first side mold 32 and the second side mold 33 are pushed upward to separate the first side mold 32 and the second side mold 33 from the base 31, and the first side mold 32 and the second side mold 33 drive the rotating column 374 to flip upward through the connecting block 378, and the rotating column 374 drives the movable column 372 to flip upward around the fourth pin shaft 373 in the movable groove 371 until the first side mold 32 and the second side mold 33 are separated from the base 31. The first side mold 32 and the second side mold 33 are in a standing state, and then the first side mold 32 and the second side mold 33 are turned horizontally, and the connecting block 378 drives the rotating column 374 to rotate 180 degrees relative to the movable column 372 through the clamping column 375, and then the first side mold 32 and the second side mold 33 are turned down and reset, and the locking block 3113 is pressed again to insert the slider 3111 into the sliding groove 323. After the spring 3114 rebounds, the locking block 3113 pops out from the rectangular groove 3112. At this time, the positions of the first side mold 32 and the second side mold 33 are swapped, and the lower cavity 322 is at the top to replace the upper cavity 321 for injection molding production. ;
