Technical Field

[0001] The utility model relates to the technical field of refrigerator bottom plate production equipment, in particular to a blanking structure of a refrigerator bottom plate production mold. Background Art

[0002] At present, refrigerator bottom plates are generally divided into two types: one is a galvanized steel bottom plate, which is mainly used for high-end refrigerators or large refrigerators. Due to its high price, it is generally not considered for ordinary refrigerators; the other is a combination of a PP hollow plate and a galvanized steel plate, which is mainly used for mid-range and low-end refrigerators and small refrigerators, and the price is cheaper than that of a fully galvanized steel bottom plate.

[0003] For the blanking process in the production process of refrigerator bottom plates, the existing blanking process of refrigerator bottom plates is generally the cooperation of a transportation table and manual clamping and positioning. This blanking method is time-consuming and laborious, and is not conducive to the repetitive production of refrigerator bottom plates. Therefore, we propose a blanking structure of a refrigerator bottom plate production mold to solve the above problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects existing in the prior art. The utility model provides a blanking structure of a refrigerator bottom plate production mold that is convenient for blanking and can perform efficient repetitive operations.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a blanking structure of a refrigerator bottom plate production mold, including: two relatively flush mounting crossbeams and a moving frame disposed between the two mounting crossbeams. Each of the mounting crossbeams is fixed with a first rack along its axial direction. A first gear is engaged with the first rack. The two ends of the moving frame respectively servo-rotate the first gear through a first driving member. Two symmetrically arranged sleeve steels are vertically fixed on the moving frame. Each sleeve steel is slidably connected with a blanking steel. A second rack is fixed on the blanking steel along its axial direction. A second gear is engaged with the second rack. A second driving member is also fixed on the moving frame. The second driving member is used to servo-rotate the second gear. The two blanking steels are connected into one body through an I-shaped frame. Mounting plates for connecting an external vacuum adsorption plate are fixed at the bottom ends of the two blanking steels.

[0006] Further, the first driving member includes a first motor fixing plate, a driving shaft, a driven shaft and a belt gear. The first motor fixing plate is connected and fixed with the moving frame, and is used to fix an external servo motor. Both the driving shaft and the driven shaft are fixed with the moving frame through coaxial rotating first bearing seats at their middle shaft sections, and both ends of them are respectively engaged and matched with the first rack through the first gear. The driving shaft and the driven shaft are driven by the belt gear and an external servo motor.

[0007] Further, the second driving member includes a second motor fixing plate, a second bearing seat, and a lifting shaft. The second motor fixing plate is fixedly connected to the moving frame and is used to fix an external servo motor. The lifting shaft is rotatably connected to the second bearing seat, and the second bearing seat is fixedly connected to the moving frame. Both ends of the lifting shaft are coaxially fixed to the second gears, and the sleeve steel is provided with tooth-exposing grooves corresponding to the second gears.

[0008] Further, both ends of the blanking steel are exposed outside the sleeve steel, and multiple groups of connecting members are annularly arranged at the exposed connection. The connecting members include three groups and are used to fix and rollingly contact the blanking steel.

[0009] Further, each connecting member includes a positioning block, an adjusting bolt, a sliding rod, and a rotating roller. The positioning block is vertically fixed to the sleeve steel and is provided with an adjusting groove. The sliding rod is coaxially fixed to the center of the rotating roller and both ends are slidably connected in the adjusting groove. The nut of the adjusting bolt is positioned on the positioning block and is fixedly connected to the end of the sliding rod at the bottom.

Multiple annularly arranged diagonal steels are also welded between the moving frame and the sleeve steel for support.

[0012] Compared with the prior art, the beneficial effects of the present utility model include: by driving the external adsorption component in a double-shaft manner, it is more convenient and efficient to carry out blanking during the die pressing process of the refrigerator bottom plate.
