Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of plastic molding, in particular to an injection molded shoe processing device and a processing method thereof. Background Art
[0002] The working principle of the horizontal shoe injection molding machine is based on the thermoplastic and high-pressure injection characteristics of plastics, and achieves efficient shoe production through a horizontal mold structure. Its core processes and technical points are as follows:
[0003] The operating principle includes the plasticizing phase, the injection phase, pressure holding, cooling, mold opening, and ejection. Plastic granules are fed from a hopper into the barrel, where they are heated to a molten state by a heating coil. A screw, driven by a drive motor, rotates, compacting, shearing, and conveying the material forward for uniform plasticization. The molten plastic accumulates in a reservoir at the screw head, where the injection cylinder propels the screw forward at high speed. The molten material is injected through a nozzle at high pressure (typically >100 MPa) into the horizontally positioned shoe mold cavity. After injection, the screw maintains pressure to compensate for material shrinkage, ensuring a complete, shrink-free sole structure. A cooling medium (water / oil) is passed through the mold to accelerate the solidification of the molten material and set the shape. A hydraulic system drives the mold plate horizontally back to open the mold, and the finished sole is removed by a robotic arm.

[0033] The present invention will be further described below in conjunction with the accompanying drawings:
[0034] like Figure 1 — Figure 5 As shown, this embodiment provides an injection molding shoe processing equipment, including an injection molding system 1, a frame 2, a fixed mold system 3, a movable mold system 5, a robot demoulding system 4 and a finished product conveying system 6. The robot demoulding system 4 is installed on the fixed mold system 3, and the motion trajectory of the robot demoulding system 4 passes between the fixed mold system 3 and the movable mold system 5, thereby taking out the finished shoes. The movable mold system 5 and the injection molding system 1 can be slidably installed on the frame 2, the fixed mold system 3 is installed on the frame 2, the movable mold system 5 and the fixed mold system 3 are molded together, and the finished product conveying system 6 is installed on the frame 2 to convey the finished shoes away. A bending adsorption device 7 is installed at the output end of the robot demoulding system 4. The bending adsorption device 7 has a bending state and a flat state. The bending adsorption device 7 is in a flat state when it grabs and fixes the sole. The bending adsorption device 7 is in a bent state when it takes out the sole. The bending adsorption device 7 extends between the fixed mold system 3 and the movable mold system 5, and separates each part of the shoe from the movable mold system 5 in turn, and then gradually takes out the shoe to achieve smooth demoulding.
[0035] Specifically, the fixed mold system 3 includes a fixed mold docking block 31 and a fixed mold 32. The fixed mold 32 is installed on the fixed mold docking block 31. The fixed mold 32 is adapted to the movable mold system 5. The fixed mold docking block 31 is provided with an injection hole 311 adapted to the injection molding system 1. The robot demoulding system 4 is installed on the fixed mold docking block 31, and then the shoes are gradually taken out. The injection molding system 1 slides on the frame 2, thereby realizing the adaptation of the injection molding system 1 and the injection molding hole 311. When the injection molding system 1 is adapted to the injection molding hole 311, the injection molding system 1 extrudes the material into the injection molding hole 311, and then extrude the material between the fixed mold 32 and the movable mold system 5 to realize the molding of the shoes.
[0036] Specifically, the movable mold system 5 includes a movable mold plate 51, a movable mold sliding rail 52 and a movable mold 53. The movable mold 53 is installed on the movable mold plate 51. The movable mold plate 51 is slidably installed on the movable mold sliding rail 52. The movable mold sliding rail 52 is installed on the frame 2. The sliding of the movable mold plate 51 realizes the opening and closing of the mold. A movable mold pushing cylinder for pushing the movable mold plate 51 to slide is installed on the frame 2.
[0037] Specifically, the robot demoulding system 4 includes a six-axis robot 41 and an adsorption substrate 42.

The two bending traction rods 75 are slidably mounted on the adsorption base plate 42 of the robot demoulding system 4. The adsorption base plate 42 is provided with a guide groove 421. The bending traction rod 75 is slidably mounted in the guide groove 421. The two bending rods 74 are respectively mounted on the first adsorption plate 71 and the second adsorption plate 76. The adsorption base plate 42 is provided with a guide groove 421. The first and second adsorption plates 71 and 76 are bent by the traction cylinder 75 for pulling the bending traction rod 75 to slide. The bending traction rod 75 drives the first adsorption plate 71 and the second adsorption plate 76 to bend.

When the shoe is in the closed position, the shoe is in the closed position, and the shoe is in the closed position, so that the shoe is in the open position and the shoe is in the closed position, the shoe is in the closed position, and the shoe is in the closed position.
[0040] The working process of the clamping assembly 73 is that after the fixed mold system 3 and the movable mold system 5 are opened, the clamping assembly 73 is clamped with the first adsorption plate 71 and the second adsorption plate 76 respectively, and under the drive of the six-axis robot 41, the first adsorption plate 71 and the second adsorption plate 76 fixed together are synchronously pressed on the sole, and then the adsorption suction cup 77 or the pneumatic clamp grabs the two ends of the sole. The role of the clamping assembly 73 at this time is to ensure that the adsorption suction cup 77 or the pneumatic clamp on the first adsorption plate 71 and the second adsorption plate 76 synchronously grabs the sole and achieves a reliable connection with the sole, and then the clamping assembly 73 rotates to release the first adsorption plate 71 and the second adsorption plate 76, and then the bending cylinder drives the corresponding bending traction rod 75 to approach each other, so that the toe position and the heel position of the sole are lifted first until the sole is completely removed. Since the sole is bent and removed, the sole is peeled off from the mold in turn, reducing the peeling force and ensuring reliable demolding.
[0041] Specifically, a clamping reference block 72 is provided on the first adsorption plate 71 and the second adsorption plate 76, and two clamping blocks 79 are provided on the clamping assembly 73. The clamping assembly 73 also includes a clamping switching motor. The two clamping blocks 79 are integrally arranged.

The clamping switching motor is transmission-connected to the two clamping blocks 79. The two clamping reference blocks 72 form gaps with the corresponding first adsorption plate 71 and second adsorption plate 76 respectively. The width of the gap is equal to the thickness of the corresponding clamping block 79. The two clamping reference blocks 72 are adapted to the clamping blocks 79 to thereby achieve the fixation of the first adsorption plate 71 and the second adsorption plate 76.
[0042] A method for manufacturing injection molded shoes using an injection molded shoe manufacturing device comprises the following steps:
[0043] S1: The robot demoulding system 4 drives the bending adsorption device 7 upward, so that the bending adsorption device 7 is away from the area between the fixed mold system 3 and the movable mold system 5.
