Description

Technical Field

[0001] This utility model relates to the technical field of shoe sole injection molding machine equipment, and in particular to a waste material clamping device for shoe sole injection molding machine. Background Technology

[0002] In the injection molding process of shoe soles, waste removal is a crucial step affecting production efficiency and product quality. Traditional waste disposal methods mainly rely on manual operation, requiring workers to manually remove the waste after injection molding. This is not only labor-intensive and inefficient but also poses safety hazards. Furthermore, manual cleaning cannot guarantee complete removal of waste, and residual waste may affect the precision of subsequent sole processing, even leading to product defects. While some existing automated waste handling devices can partially replace manual labor, they still suffer from insufficient structural stability, poor gripping adaptability, and inconsistent waste transport, resulting in low waste removal efficiency and failing to meet the high-efficiency and precision requirements of modern injection molding production.

[0003] Chinese patent publication number (CN 203031879 U) discloses a material handling device for a shoe sole injection molding machine, which includes a gantry frame with a base on the gantry frame and a conveyor belt below the base. The base is equipped with a material handling robotic arm and an auxiliary processing robotic arm driven by a drive device. However, this material handling device for shoe sole injection molding machines has insufficient automation in its waste cleaning method, resulting in low efficiency, poor stability, and a high risk of waste residue. Therefore, a waste handling device for shoe sole injection molding machines is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of insufficient automation in the waste cleaning method of the material handling device for shoe sole injection molding machines, which leads to low efficiency, poor stability, and high risk of waste residue. Therefore, this invention proposes a waste handling device for shoe sole injection molding machines.

Enhanced structural stability: The double-layer frame design provides stronger support, ensuring that the device will not shake during high-speed movement, improving overall stability; Improved motion accuracy: The linear guide rail and rack work together to make the movement of the diagonal support frame more stable and precise, avoiding positioning deviations caused by mechanical vibration; Optimized space utilization: The design of the diagonal support frame makes full use of vertical space, allowing the clamping mechanism to cover a larger working range and improving waste material cleaning efficiency.

[0006] Preferably, the horizontal drive device includes a drive motor, one end of which has a transmission shaft, and the other end of which has a fixed seat. A sliding seat is mounted on the transmission shaft, and a connecting seat is mounted on the sliding seat. Several sets of gripping components are provided at the bottom of the connecting seat and the inclined support frame. The motor + transmission shaft structure provides stable power output, ensuring that the gripping mechanism can move quickly and accurately to the target position.

The H-shaped positioning block ensures that the shoe sole workpiece is in the correct position before clamping, avoiding clamping failure due to displacement; the double-rod cylinder provides uniform clamping force, keeping the shoe sole workpiece stable during clamping and improving the accuracy of waste separation; the double-piston rod design allows the pressure plate to move quickly, shortening the waste cleaning cycle and improving overall production efficiency.

[0009] Preferably, a second linear guide rail is provided on one side of the lower frame, and a mounting plate is provided on the top of the second linear guide rail. Material discharge slots are provided on both sides of the center of the mounting plate.

A flipping plate is provided on each side of the mounting rod, and the flipping plate cooperates with the linkage mechanism. The servo motor drives the mounting plate to move, allowing waste material to be automatically conveyed to the material discharge slots, reducing manual intervention. The flipping plate, in cooperation with the linkage mechanism, realizes automatic dumping of waste material, preventing waste material accumulation from affecting subsequent operations. The mounting plate can move back and forth to adapt to different specifications of shoe sole waste material, improving the versatility of the device.

[0010] Preferably, the shoe sole workpiece, the unloading trough, and the flipping plate are arranged sequentially from top to bottom and are interconnected. The three work together to form a complete waste cleaning process, from clamping to unloading in one go, improving the continuity of operations; the automated linkage design reduces dependence on operators, reduces human error, and improves production safety; the process of waste from clamping to discharge is seamlessly connected, avoiding efficiency loss due to downtime.

[0011] The advantages of this utility model are: This application significantly improves the efficiency and reliability of cleaning waste from shoe sole injection molding through innovative mechanical structure and automated control. Its double-layer frame design enhances overall stability, ensuring the gripping mechanism does not wobble during high-speed movement and improving positioning accuracy. The horizontal drive device adopts a modular design of motor + drive shaft + sliding seat, enabling the gripping components to move quickly and accurately to the target position and achieving synchronous control of multiple grippers. The gripping components use arc-shaped plate stacked clamping blocks, which can adapt to waste materials of different shapes and thicknesses, ensuring a stable grip without damaging the workpiece. Simultaneously, in conjunction with the clamping components, the waste material remains stable during gripping, preventing it from falling off or shifting. The servo-driven mounting plate of the lower frame works in conjunction with the flipping mechanism to achieve automatic waste conveying and dumping, forming a complete waste cleaning process, reducing manual intervention and improving operational continuity. Overall, this device achieves fully automated operation from waste gripping to discharge, significantly improving production efficiency, reducing labor costs, and ensuring thorough waste cleaning, preventing residual waste from affecting product quality.

[0023] The implementation principle of this embodiment is as follows: Initial positioning phase: When the device is started, the second linear guide rail 19 of the lower frame 18, driven by the servo motor 24, moves the mounting plate to the standby position; at the same time, the horizontal drive device of the upper frame 22 positions the diagonal brace frame 4 to the initial coordinates through the drive motor 7 and the transmission shaft; the H-shaped positioning block 13 completes the precise positioning of the shoe sole workpiece 12, and the double-rod cylinder 17 drives the double piston rod to press down the pressure plate 14 to ensure that the workpiece is fixed.

[0024] Waste handling stage: The first linear guide rail 1 and the first rack 2 work together to guide the inclined support frame 4 to move along a predetermined trajectory to above the waste material; the clamping cylinder 9 in the clamping assembly drives the gripper 10 to move through the connecting bolt 8, and the clamping blocks 11 with the arc plates stacked on top of each other adapt to the shape of the waste material to achieve multi-point contact clamping.

[0025] Waste transfer stage: The sliding seat 6 of the horizontal drive device moves along the transmission shaft, driving the connecting seat 5 and the clamping assembly to move the waste material to the area of ​​the lower frame 18. The mounting plate is precisely positioned under the control of the servo motor 24, so that the feeding trough is aligned with the clamping position. The linkage mechanism 20 on the mounting rod 15 synchronously adjusts the angle of the flipping plate 16 to prepare for subsequent unloading. After the gripper 10 is released, the waste material falls accurately into the feeding trough. The flipping plate 16 completes a 90° flipping action under the action of the linkage mechanism 20, ensuring that the waste material is completely removed from the working area. The mounting plate resets along the second linear guide rail 19, and the clamping assembly returns to the initial position.
