Description

Technical Field

[0001] This utility model belongs to the field of press mold assembly technology, and in particular to a quick mold assembly auxiliary device. Background Technology

[0002] One of the key issues to address in improving stamping production efficiency is how to achieve rapid die installation, especially given the predicament of upgrading outdated equipment. The initial equipment installation plan did not consider whether the spare workbench could facilitate rapid die replacement. Faced with an increasingly challenging market economy and safety constraints, the current die replacement method for older equipment—manually pushing and pulling the dies into the equipment—impacts stamping production efficiency, hindering the planned output of stamping shifts. Furthermore, the fatigue caused by manual die installation easily leads to safety accidents. Utility Model Content

[0017] like Figure 1 and Figure 2As shown, a quick mold loading auxiliary device includes a base 1, a support frame 2, movable guide rails 3, a lifting mechanism 4, stoppers 5, and a connecting component 6. The support frame is fixed on the base, and a pair of movable guide rails are located at the top of the support frame. The pair of movable guide rails are used to transport the mold. The lifting mechanism is located inside the support frame and is used to support and lift the pair of movable guide rails. The pair of movable guide rails can transport the mold at an angle on the support frame through the lifting mechanism. Two stoppers are evenly distributed on the rear end of the pair of movable guide rails, and the guide rail stoppers are movably connected to the support frame. The connecting component can be installed on the side of the press worktable and is connected to the front end of the pair of movable guide rails.

[0018] like Figure 3 As shown, the structure of the support frame 2 is as follows: the top of the support frame is divided into a front limiting frame 201 and a rear limiting frame 202; the limiting groove of the front limiting frame is used to support the movable guide rail and limit the front end of the movable guide rail to prevent the movable guide rail from sliding along its own width direction; the limiting groove of the rear limiting frame is used to limit the rear end of the movable guide rail to prevent the movable guide rail from sliding along its own rear end direction; advantages: simple overall structure, low manufacturing cost, easy maintenance, and strong load-bearing capacity.

[0019] like Figure 4 As shown, the structure of the movable guide rail 3 includes two upright plates 301, which are symmetrically arranged. A connecting pin 302 is distributed between the two upright plates. The two upright plates are combined into a guide rail by the connecting pin. Multiple rollers 303 are distributed at intervals along the length direction in the upper cavity of the guide rail. A mold limiting block 304 is provided on the rear end of the guide rail. The mold limiting block is used to restrict the movement of the mold along the rear end direction of the guide rail. A slot 305 is provided on the front end face of the two upright plates. Advantages: The overall structure is simple, the manufacturing cost is low, it is easy to maintain, and the load-bearing capacity is strong. The rolling support of the mold by the rollers can reduce the coefficient of friction, making it easier to push the mold into the press and reducing labor intensity.

[0020] like Figure 3 As shown, the lifting mechanism 4 has the following structure: it includes a worm gear pair 401, a lead screw 402, and a movable limit frame 403. The worm gear pair is fixed inside the support frame. The vertical lead screw and the worm gear in the worm gear pair are driven by threaded engagement. The upper and lower ends of the lead screw are fixed inside the support frame by bearings. The movable limit frame is fixedly connected to the upper end of the lead screw. Advantages: The lifting mechanism has a simple structure, low manufacturing cost, self-locking function, and is easy to operate, which helps to reduce labor intensity. In the initial position, the support surface of the movable limit frame is flush with the support surface of the front limit frame, which can strengthen the load-bearing capacity of the front limit frame. The movable limit frame can also further prevent the movable guide rail from sliding along its own width direction.

[0021] like Figure 4As shown, the structure of the guide rail stop 5 includes a pin seat 501 and a pin 502. The pin seat is fixed to the rear end face of the movable guide rail, and the pin is installed on the pin seat. The support frame has a pin hole 203 corresponding to the pin. The lower end of the pin is inserted into the pin hole to lock it. Advantages: The overall structure is simple, the manufacturing cost is low, and it is easy to operate.

[0022] like Figure 5 As shown, the structure of the connecting component 6 includes a connecting block 601, which is fixed to the side of the press worktable by fasteners 602. The top of the connecting block is provided with a connecting groove 603, which communicates with the groove cavity of the press worktable 7. A guide rail support crossbar 604 is fixed in the connecting groove. There are two sets of the connecting components. The guide rail support crossbar on each set of connecting components is used to support the front end of its corresponding movable guide rail. Advantages: 1) The connecting groove enables quick docking between the movable guide rail and the press worktable; 2) When conveying the mold, the guide rail support crossbar is used to assist in supporting the inclined movable guide rail, which can strengthen the load-bearing capacity of the front limit frame; 3) The overall structure is simple, the manufacturing cost is low, and the labor intensity is reduced.

[0023] like Figure 1 and Figure 6 As shown, a pair of movable guide rails are placed on the front limit frame and the movable limit frame. The front and middle parts of the movable guide rails are supported and limited by the front and movable limit frames. The rear end of the movable guide rails abuts against the rear limit frame, and the pin on the movable guide rails is inserted into the pin hole on the rear limit frame. The lifting mold is placed on the pair of movable guide rails, and the mold limiting block on the rear end of the movable guide rails limits the mold. Then, the front end of the movable guide rail is connected to the connecting groove on the press worktable, so that the front end of the movable guide rail is engaged with the guide rail support crossbar. The pin is pulled out, and the worm gear spokes are manually driven, and the movable limit frame lifts the movable guide rails. The guide rail support crossbar serves as a rotation support point. When the middle or rear end of the movable guide rail is lifted by the movable limit frame, it can rotate around the guide rail support crossbar, with a rotation angle of no more than 3°. This ensures lifting safety and also makes it easier to push the mold 8 into the press.
