[0002] Existing soles are usually formed by mold injection molding, and the injection molding step requires the use of a turntable machine, which is also called an injection disc machine.

[0003] A Chinese patent with announcement number CN212288414U discloses a mold pull-out type injection disc machine for sole bonding, which includes a base, a disc, a reduction motor, multiple groups of support columns, an annular plate, multiple combined mold mechanisms, multiple groups of pressing mechanisms, a first mounting frame, a mechanical slide, two groups of connecting rods, multiple groups of first slide rails, a second slide rail, a second mounting frame and an injection mechanism. The disc is rotatably arranged on the base, and molds can be slidably arranged on multiple groups of first slide rails. The mechanical slide includes a frame, a servo motor, a transmission screw and a sliding seat. The sliding seat is arranged on the transmission screw. Two groups of connecting rods are fixedly arranged on the sliding seat. Electromagnets are arranged at the rear end ends of the two groups of connecting rods. The injection mechanism is arranged on the second mounting frame, and the injection mechanism is located directly above the second slide rail.

[0004] The above-mentioned clamping mechanism includes a first clamping mold, a second clamping mold, two sets of fixed columns, two sets of hinged rods and two sets of torsion bars. The specific operation is to rotate the two sets of torsion bars so that the two sets of hinged rods respectively push the first clamping mold and the second clamping mold to rotate toward or away from each other to realize the opening and closing operation. Since the injection disc machine is provided with a number of clamping mechanisms distributed around the disc, if the machine is in a high-load operation state for a long time, the above-mentioned manual operation method will cause a huge workload and will cause the staff to be in a high-load working state for a long time, making it difficult to keep up with the working speed of the machine and easily causing physical and mental fatigue of the staff, which does not meet the future development needs of the enterprise.

[0013] By adopting the above technical solution, the linkage plate drives the two linkage grooves to move, and the arc-shaped linkage grooves and the matching linkage rods drive the left frame and the right frame to realize synchronous movement in opposite directions around the hinge, so as to achieve the linkage purpose.

[0014] It is further configured as follows: the left frame and the left lower mold are detachably fixedly connected via a connecting assembly, wherein the connecting assembly includes a connecting plate fixedly arranged on the left frame and a locking bolt passing through the connecting plate and threadedly connected to the left lower mold.

[0015] By adopting the above technical solution, the locking bolt passes through the connecting piece and is threadedly connected to the left lower mold to achieve the purpose of detachable fixation between the two.
