Description

Technical Field

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

[0002] Foam soles have the advantages of being light in material, easy to wear, and soft and comfortable in texture, but their disadvantage is poor anti-slip performance. Therefore, this type of sole is usually provided with a pattern on the bottom for anti-slip performance. Soles made of this type of material are usually produced by injection molding equipment. Common injection molding equipment is mostly vertical. However, due to the large production volume of soles, the single production efficiency of vertical injection molding equipment is slow, and it is gradually being replaced by wheel-type injection molding equipment. The wheel-type injection molding equipment is provided with multiple injection molds, 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 retrieving station and cleaning station in sequence.

[0003] The injection mold is usually provided with a single or two cavities, and the upper mold squeezes the raw material in the cavity and cools it into shape. However, since the molded sole is sunken in the cavity, its bottom and side walls are not separated from the cavity, making it difficult to remove the sole. 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 to separate 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.

[0019] 2. This 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 pushed to flip upward. The first side mold and the second side mold drive the rotating column to flip upward through the connecting block. 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.

The clamping action of the locking block and the slide groove limits 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 and pushed to retract 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. This foam sole molding injection mold molding equipment is equipped 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, taking away the heat during the injection molding process and accelerating the rapid cooling and molding of the insole.

The turntable 2 is driven by a motor, and the motor is mounted inside the frame 1. A material removal mechanism 5 is installed on the side of the frame 1 away from the injection molding machine 4.

[0036] The injection mold 3 includes a base 31, which is a rectangular plate with an L-shaped longitudinal section. A first side mold 32 is provided on the upper surface of the base 31, and a second side mold 33 is provided on the upper surface of the base 31 on one side of the first side mold 32. When the first side mold 32 and the second side mold 33 are close to each other, the cavities of the two are merged. A top plate 34 is provided above the first side mold 32 and the second side mold 33, and a sealing member 35 is provided at the bottom of the top plate 34 for sealing between the top plate 34 and the upper cavity 321 and the lower cavity 322. A linkage mold opening mechanism 36 is installed on the front side of the top plate 34, the first side mold 32 and the second side mold 33 for linkage mold opening of the three-way pressing mold 341, the first side mold 32 and the second side mold 33. A flip seat 37 is installed on the upper surface of the base 31 at the rear side of the first side mold 32 and the second side mold 33. The flip seat 37 is fixed at the corner of the upper surface of the base 31, and the upper surface of the base 31 is close to the left and right The edges of both sides are provided with locking mechanisms 311 for connecting the base 31 with the first side mold 32 and the second side mold 33. A water-cooling pipe 312 is provided at the position corresponding to the position of the upper surface of the base 31 and the lower cavity 322. The water-cooling pipe 312 is arranged in an S-shaped zigzag pattern on the upper surface of the base 31 and forms two layers. The bottom of the top plate 34 is connected to the pressing mold 341. A hinge 342 is connected between the rear side of the top plate 34 and the base 31. The top plate 34 is hinged to the base 31 through the hinge 342 and can be flipped upward to open the mold. The water-cooling pipe 312 is externally connected to cooling water and is movably connected to the lower cavity 322. The water-cooling pipe 312 is made of copper metal with good thermal conductivity. By passing cooling water into the water-cooling pipe 312, 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, thereby accelerating 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 provided below the upper plate 361, and screws 363 are provided on both the upper plate 361 and the lower plate 362. There are several screws 363, 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 364, and a folding rod 365 is provided on the outside of the first pin 364. A torsion spring 366 is installed between the folding rod 365 and the first pin 364. 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 36 4 is provided with a connecting shaft 367, which passes through the two folding rods 365 and then extends from the front side to facilitate the top block 54 to push it up. A hinge seat 368 is installed on the upper surface of the middle part of the folding rod 365. A hinge groove is provided in the hinge seat 368. The bottom of the connecting rod 3610 is inserted into the hinge groove. 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. A second pin shaft 369 is connected to the front side of the upper plate 361, and the connecting rod 3610 is sleeved on the outside of the second pin shaft 369. A third pin shaft 3611 is provided between the bottom end of the connecting rod 3610 and the hinge seat 368.

[0038] Specifically, there are two lower plates 362, and the two lower plates 362 and the upper plate 361 are all mounted on the first side mold 32, the second side mold 33 and the front side of the top plate 34 by screws 363, so that the upper plate 361 and the lower plate 362 can be disassembled, and the positions of the upper plate 361 and the lower plate 362 can be adjusted after the first side mold 32 and the second side mold 33 are flipped over. There are two folding rods 365, which are symmetrically distributed on the front sides of the two lower plates 362. The two folding rods 365 are rotatably connected by the connecting shaft 367. The two folding rods 365 are rotatably connected. One end of 65 away from the connecting shaft 367 is rotatably connected to the two lower plates 362 via the first pin shaft 364. The length of the two folding rods 365 is greater than the distance between the two first pin shafts 364. In the unmolded state, the two folding rods 365 form a V shape downward. Due to the length limitation of the connecting rod 3610, the height of the connecting shaft 367 is not lower than the lowest position of the lower plate 362 at this time. Therefore, the torsion spring 366 still has a downward torque force at this time, and the torque force of the torsion spring 366 is used to pull the first side mold 32 and the second side mold 33 to merge.

[0039] Furthermore, there are two connecting rods 3610, the top ends of the two connecting rods 3610 are rotatably connected to the upper plate 361 via the second pin shaft 369, and the bottom ends of the two connecting rods 3610 are rotatably connected to the hinge seat 368 via the third pin shaft 3611. The first pin shaft 364 is fixed to the front side of the lower plate 362, and the second pin shaft 369 is fixed to the front side of the upper plate 361. The connecting shaft 367 and the third pin shaft 3611 are not connected to the lower plate 362 and the upper plate 361, and the first pin shaft 364 and the second pin shaft 369 are both provided with a card key to meet the requirements of the folding rod 365 and the connecting rod 3610 being stuck on them and rotating.

[0040] Furthermore, a movable groove 371 is provided inside the flip seat 37, and a movable column 372 is provided inside the movable groove 371.

The slider 3111 is in the shape of an arc block, and the slide groove 323 is also in the shape of a circular arc. The arc center of the slider 3111 is aligned with the fifth pin 379. The axes are on the same vertical line. When the spring 3114 is in a normal stretched state, the locking block 3113 extends out from the rectangular groove 3112. The locking block 3113 and the slider 3111 are stuck in the slide groove 323 to form a sliding connection with the first side mold 32 and the second side mold 33. The locking mechanism 311 is used to maintain the stability of the connection between the first side mold 32 and the second side mold 33 and the base 31 during the injection molding process, and is used to guide the first side mold 32 and the second side mold 33 to move away from each other.

[0045] The upper surface of the hydraulic telescopic rod 52 is connected to the top block 54, and the center line of the top block 54 is on the same vertical line as the center line of the connecting shaft 367.

A first rotating shaft 510 is provided inside the clamping seat 59. A clamping claw 511 is sleeved on the outer side of the first rotating shaft 510. There are two clamping claws 511, which are symmetrically arranged up and down. The clamping claws 511 are rotatably connected to the clamping seat 59 through the first rotating shaft 510. A first gear 512 is also connected to the outer side of the first rotating shaft 510. There are two first gears 512 and the first rotating shaft 510. The two first rotating shafts 510 are arranged up and down. The two first gears 512 are meshed with each other to realize the reverse rotation of the two clamping claws 511. One side of one of the first gears 512 is meshed with a second gear 513, that is, the first gear 512 at the bottom is meshed with the second gear 513. A second rotating shaft 514 is provided through the middle of the second gear 513. The second rotating shaft 514 passes through the clamping seat 59 and is connected to a clamping motor 515.

[0047] The method of using this embodiment is as follows: when the user actually uses the injection molding equipment to produce foam soles, first, the raw materials are 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 to 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 extends through the fixed block 53 to push the top block 54 The top block 54 moves upward, exerting 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 364. At the same time, the two folding rods 365 push the two lower plates 362 away from each other via the first pin 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 379 via 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 via 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 via the hinge seat 368. The upper and lower ends of the connecting rod 3610 rotate relative to the second pin 369 and the third pin 3611, respectively, so that the connecting rod 3610 pushes the upper plate 361 upward via the second pin 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. 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, clamping the sole in the upper cavity 321, and cooperating 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, and the middle shaft 55 drives the electric push rod 58 to turn, and when the clamping claws 511 are loosened, the sole falls to be collected, and after the sole is taken out, the hydraulic telescopic rod 52 contracts and drives the top block 54 to move downward, and 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 upward, 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 and second side molds 32 and 33 are in an upright position. The first and second side molds 32 and 33 are then rotated laterally. The connecting block 378 drives the rotating column 374 to rotate 180 degrees relative to the movable column 372 via the locking column 375. The first and second side molds 32 and 33 are then flipped downward and reset. The locking block 3113 is pressed again, inserting the slider 3111 into the slide slot 323. After the spring 3114 rebounds, the locking block 3113 pops out of the rectangular slot 3112. The first and second side molds 32 and 33 are now swapped, with the lower cavity 322 at the top, replacing the upper cavity 321, for injection molding.
