Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and specifically to an oil-gas mixing pressing mechanism. Background Technology

[0002] The sole pressing machine is one of the most crucial steps in shoe manufacturing. Currently, most wall-mounted sole pressing machines on the market use hydraulic pressure for securing the sole. In production, they need to be used in conjunction with a sole pressing mold to achieve the required quality. However, the variety of shoes required by humans is vast, and each type requires a specially customized sole pressing mold, making the process complex and costly. There is also a hydraulic sole pressing machine on the market, which, while providing a good seal to the bottom and sides, suffers from unstable pressure, resulting in uneven stress on the shoes and a tendency to wrinkle.

[0003] To address the above issues, a new oil-gas mixing and pressing mechanism has been developed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an oil-air hybrid pressing mechanism. This mechanism is designed as a sealed groove on all four sides, with the top cover of the pressing base sealed by a pouch. This encloses the left and right pressing edges and the front and back tightening within the sealed pouch, forming a closed, soft processing area. In use, the shoe is placed in the groove within the pouch, and then the pouch is inflated to deform it, thus fully encasing the shoe. The pressing and tightening devices of the hydraulic mechanism then press down on the shoe's perimeter within the pouch, ensuring even pressure on the shoe's sides and top and bottom surfaces. This structure not only provides a firm seal but also eliminates the need for special molds for different shoe types, saving costs and increasing efficiency while improving product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An oil-gas mixing and pressing mechanism includes a pressing base, a pressing edge device, and a tightening device. The pressing edge device is arranged in two sets symmetrically on the left and right sides of the pressing base, and the tightening device is arranged in two sets symmetrically on the front and rear sides of the pressing base. A groove is provided in the middle of the upper part of the pressing base, and a bag is placed in the groove. The bag is sealed to the upper edge of the pressing base by a pressing plate. An air inlet and an air outlet are respectively provided on the left and right sides of the pressing base. The pressing edge device includes a pressing edge cylinder and a side pressing block. The head of the pressing edge cylinder is fixedly connected to the side of the pressing base, and a pressing edge sealing ring is provided between the head of the pressing edge cylinder and the pressing base. The tightening device includes a tightening cylinder seat and a tightening cylinder. The tightening cylinder seat is fixed to the side of the pressing base, and the head of the tightening cylinder is fixed to the tightening cylinder seat at the lower part of the pressing base.

[0007] Furthermore, each set of pressing devices has several pressing cylinders arranged in parallel, and the piston rod of each pressing cylinder extends into the interior of the pressing base, and a side pressing block is fixed on the piston rod of each pressing cylinder.

[0008] Furthermore, the tightening device also includes a lower tightening slide rod, a tightening slider, a tightening slide base, an upper tightening slide rod, and a tightening block. The lower part of the tightening slider is slidably connected to the tightening cylinder seat through the lower tightening slide rod. The tightening slider is also fixedly connected to the piston rod of the tightening cylinder. The upper part of the tightening slider is slidably connected to the tightening slide base through the upper tightening slide rod.

[0009] Furthermore, the upper tensioning slide rod extends into the interior of the pressure base, and the other end of the upper tensioning slide rod is fixedly connected to the tensioning block. A tensioning sealing ring is also provided between the tensioning slide block and the pressure base.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] An oil-gas hybrid pressing mechanism includes a pressing base, pressing edge devices, and tightening devices. Two sets of pressing edge devices are symmetrically arranged on the left and right sides of the pressing base, and two sets of tightening devices are symmetrically arranged on the front and rear sides of the pressing base. A groove is provided in the center of the upper part of the pressing base, and a pouch is placed inside the groove. By designing the pressing mechanism as a sealed groove on all four sides, and sealing the top cover of the pressing base with the pouch, the left and right pressing edges and the front and rear tightening devices are all wrapped inside the sealed pouch, forming a closed soft processing position. In use, the shoe is placed in the groove position inside the pouch, and then air is inflated into the pouch, deforming it to fully wrap the shoe. The pressing edge devices and tightening devices of the hydraulic mechanism then press the shoe around the pouch, ensuring that the shoe's sides, top, and bottom are evenly stressed. This structure not only provides a firm seal but also eliminates the need for special molds for different shoe types, saving costs and increasing efficiency while improving product quality.
