Description

Technical Field

[0001] The utility model relates to the technical field of shoe-making equipment, in particular to a quick mold-changing structure of a toe shaping mechanism. Background Art

[0002] A toe molding machine is a device used to shape the toe during the production and processing of shoes. During the shaping process, the toe is usually shaped by extrusion between a top mold and a bottom mold. However, when the existing toe molding machine is in use, the molds on the molding machine are mostly fixedly installed, which makes it difficult to disassemble and replace the molds. Since different toes require different molds, a lot of time is required for mold replacement during the production process, which affects the production efficiency. Therefore, the applicant proposes a quick mold change structure for the toe molding mechanism. Utility Model Content

[0003] The main purpose of the utility model is to provide a quick mold change structure of a toe shaping mechanism, aiming to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model proposes a quick mold-changing structure of a toe molding mechanism, including a top mold, the top mold including a base, a locking member movably mounted on the base, and a driving mechanism, the locking member being located below the base, and the locking member being driven by the driving mechanism between a position close to the bottom wall of the base and cooperating with the bottom wall of the base to clamp the mold and a position away from the bottom wall to loosen the mold.

[0005] The technical solution of the utility model is that a locking piece driven by a driving mechanism is movably installed under the base, and the locking piece can move between a position close to the bottom wall of the base and a position away from it as driven by the driving mechanism. When the locking piece moves toward the bottom wall of the base, it can cooperate with the bottom wall of the base to clamp the mold, and when it moves toward the direction away from the bottom wall of the base, it can loosen the mold, thereby realizing a detachable fixing structure between the mold and the top mold. Compared with the traditional one, the utility model can quickly replace the mold, effectively improves the production efficiency, and reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model provides a quick mold changing structure of a toe shaping mechanism.

[0012] In the embodiment of the utility model, Figures 1 to 2 As shown, the quick mold-changing structure of the toe molding mechanism includes a top mold 100, which includes a base 1, a locking member 2 movably mounted on the base 1, and a driving mechanism. The locking member 2 is located below the base 1, and the locking member 2 can be driven by the driving mechanism between a position close to the bottom wall of the base 1 and cooperating with the bottom wall of the base 1 to clamp the mold 200 and a position away from the bottom wall of the base 1 to release the mold 200.

[0013] The technical solution of the utility model is that a locking piece driven by a driving mechanism is movably installed under the base, and the locking piece can move between a position close to the bottom wall of the base and a position away from it as driven by the driving mechanism. When the locking piece moves toward the bottom wall of the base, it can cooperate with the bottom wall of the base to clamp the mold, and when it moves toward the direction away from the bottom wall of the base, it can loosen the mold, thereby realizing a detachable fixing structure between the mold and the top mold. Compared with the traditional one, the utility model can quickly replace the mold, effectively improves the production efficiency, and reduces the production cost.

[0014] Specifically, the base 1 and the locking piece 2 are plate-shaped, and the driving mechanism includes a first telescopic cylinder 3 and a long strip-shaped linkage piece 31. The linkage piece 31 is sleeved on the piston rod of the first telescopic cylinder 3 and fixedly connected to the cylinder body of the first telescopic cylinder 3. Connecting rods 32 that can movably pass through the base 1 are fixed at both ends of the linkage piece 31. The end of the connecting rod 32 away from the linkage piece 31 is fixedly connected to the locking piece 2. When the piston rod of the first telescopic cylinder 3 is extended, the cylinder body of the first telescopic cylinder 3 can be forced to drive the linkage piece 31 upward, thereby driving the locking piece 2 to move toward the direction close to the bottom wall of the base 1 through the connecting rod 32 until the mold 200 is clamped. When the piston rod of the first telescopic cylinder 3 is retracted, the cylinder body of the first telescopic cylinder 3 can be forced to drive the linkage piece 31 to move downward, thereby driving the locking piece 2 to move toward the direction away from the bottom wall of the base 1 through the connecting rod 32 until the mold 200 is released.

[0015] Specifically, the locking member 2 is fixedly provided with a positioning block 21 for plugging and positioning with the mold 200. The mold 200 can be installed on the locking member 2 by plugging and matching with the positioning block 21, and then the locking member 2 is driven by a driving mechanism to move to the matching base 1 to clamp the mold 200.

[0016] Specifically, a U-shaped opening 11 is provided at a position of the base 1 corresponding to the mold 200 for observing, placing, and removing the mold 200 .

[0017] Specifically, the top mold 100 also includes support rods 4 arranged on the left and right sides of the base 1. The support rods 4 are provided with slots 41 for the edge of the base 1 to movably extend into. The base 1 is pivotally mounted with a locking bolt, and the locking bolt can be pivoted relative to the support rods 4 between positions for locking and releasing the base 1.

[0018] Specifically, first screw holes connected to the slot 41 are provided at both ends of the support rod 4, and the locking bolt includes a first bolt 51 screwed into the first screw hole. The rod portion of the first bolt 51 can move between a position that is partially against and away from the base 1 as the first bolt 51 pivots. The base 1 can be clamped, loosened, and the front and rear positions of the base 1 can be adjusted by pivoting the first bolts 51 at both ends of the support rod 4.

[0019] Specifically, a second screw hole connected to the slot 41 is provided on the side of the support rod 4 away from the base 1, and the locking bolt includes a second bolt (not shown) screwed on the second screw hole. The rod portion of the second bolt can move between a position that is partially against and away from the base 1 as the second bolt pivots. The base 1 can be clamped, loosened, and the left and right positions of the base 1 can be adjusted by pivoting the second bolts on the two support rods 4.

[0020] Specifically, there is also a second telescopic cylinder 6, the cylinder body of the second telescopic cylinder 6 is fixed to the bottom of the end of the support rod 4 close to the mold 200, the piston rod of the second telescopic cylinder 6 is connected to a tension spring 7, and the end of the tension spring 7 away from the piston rod of the second telescopic cylinder 6 is detachably connected to the outer side of the mold 200. When the locking piece 2 clamps the mold 200, the piston rod of the second telescopic cylinder 6 retracts to stretch the tension spring 7 to generate tension to further fix the mold 200. When the locking piece 2 releases the mold 200, the piston rod of the second telescopic cylinder 6 extends to contract the tension spring 7 to eliminate the tension generated on the mold 200.

[0021] Specifically, the two ends of the tension spring 7 are detachably connected to the outer side of the mold 200 and the piston rod of the second telescopic cylinder 6 through a hook structure.

[0022] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
