Description

Technical Field

[0001] The utility model relates to the technical field of shoe-making equipment, in particular to a top-pressure cylinder used for a toe shaping mechanism. Background Art

[0002] The toe shaping machine is a device used to shape the toe during the production and processing of shoes. During the shaping process, the toe is put on the shoe last, and the mold supported by elastic material cooperates with the shoe last to perform bidirectional extrusion and maintain the shape for a period of time.

[0003] like Figure 3 The mold shown in the figure mainly adopts the existing toe molding machine when in use. The mold is pushed from the outside by the actuator end of the cylinder to force the mold and the toe to remain against each other. The mold is arc-shaped as a whole. The number of cylinders is usually multiple and spaced apart along the outer wall of the mold. Although multiple positions of the mold are pushed respectively by multiple cylinders, the travel trajectory of the actuator end of the cylinder is a straight line and cannot be changed. It is difficult to adjust the angle appropriately during the pushing process of the mold. The actuator end continuously pushes the local position of the mold in a fixed direction, which can easily cause the final mold to be arched at the position between the actuator ends of two adjacent cylinders. The arched part does not maintain sufficient contact with the toe, resulting in poor toe molding effect and the need for re-molding, which reduces production efficiency and increases production costs. Summary of the invention

[0004] The main purpose of the utility model is to provide a top-pressing cylinder for a toe shaping mechanism, aiming to enable the cylinder execution end to perform adaptive angle adjustment during the process of pushing the mold, so as to ensure that each position of the mold can maintain full contact with the toe.

[0005] To achieve the above-mentioned purpose, the utility model proposes a top-pressure cylinder for a toe molding mechanism, comprising a cylinder body and a piston rod, and also comprising an L-shaped swinging piece, the free end of the piston rod is movably connected with a mounting block, the mounting block can make vertical reciprocating motion relative to the free end of the piston rod and has a locking structure for locking the mounting block, the mounting block is provided with a slot for the lower end of the swinging piece to extend into, the slot is provided with a pin, the lower end of the swinging piece extends into the slot and is movably sleeved on the pin, so that the swinging piece can swing horizontally relative to the mounting block.

[0006] Preferably, a strip groove is provided on the top of the cylinder body, and a moving block connected to the free end of the piston rod is provided in the strip groove. When the piston rod is extended or retracted, the moving block can be driven to extend or retract into the strip groove. A tension spring is also provided, and the tension spring is used to apply an elastic force to the moving block to move in the direction of retracting into the strip groove. The mounting block is movably connected to the moving block.

[0007] Preferably, one end of the movable block is exposed and formed with a connecting portion, the connecting portion is provided with a vertically extending slide groove, the mounting block is formed with a slide rail suitable for the slide groove, and the mounting block is inserted into the connecting portion through the cooperation of the slide groove and the slide rail.

[0008] Preferably, the locking structure comprises a screw rod, the screw rod is screwed to the free end of the piston rod, and the upper end of the screw rod passes through the free end of the piston rod and then extends into the slide groove and is screwed to the mounting block.

[0009] Preferably, a top spring is further provided, wherein the top spring is sleeved on the screw rod, the lower end of the top spring elastically abuts against the free end of the piston rod, and the upper end of the top spring elastically abuts against the bottom wall of the mounting block.

[0010] Preferably, the connecting portion is further provided with a vertically extending limiting groove, and a limiting rod is provided on one side of the mounting block close to the limiting groove, and a portion of the limiting rod extends into the limiting groove.

When working, the piston rod is extended to make the swinging member approach and push the mold. In the process of contacting and pushing the swinging member with the mold, the swinging member is forced to make a horizontal swinging motion, thereby realizing automatic angle adjustment, so as to ensure that the swinging member always keeps full contact with the outer wall of the mold during the process, avoids the mold from arching, and thus keeps full contact with the toe cap, thereby improving the shaping effect of the toe cap, effectively improving the production efficiency and reducing the production cost.
