Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a hydraulic arm shock-absorbing mold changing frame. Background Technology

[0002] Existing stamping profile processing methods mostly employ a combination of a die and a punch for punching. For example, the Chinese utility model patent (authorization announcement number: CN219027772U, name: die frame) includes: an upper die base, an upper pressure plate, and a lower die base; the upper pressure plate is connected to the bottom of the upper die base, and the lower end face of the upper pressure plate is used to install the etching die; the lower die base is correspondingly located below the upper die base and is used to support the material; wherein, the lower end face of the upper pressure plate or the upper end face of the lower die base is provided with a boss, the thickness of the boss is greater than the thickness of the etching die, so that when the die is closed, there is an uncut height between the etching die and the lower die base, and the uncut height is equal to the thickness difference between the boss and the etching film. The mold frame of this application can ensure that the material is not overcut and can also extend the service life of the etching mold. However, when changing the upper mold on the press, the upper and lower molds must be closed and pushed out of the equipment. Then the entire upper mold structure needs to be placed into the flipping rack and flipped before the mold can be changed. The disadvantages of this mold changing method are: slow mold changing speed, long cycle, high labor intensity, serious impact on production progress and equipment capacity. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulic arm shock-absorbing mold changing frame to overcome the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a hydraulic arm shock-absorbing mold changing frame, including a support frame, on which a large load-bearing component is installed. The large load-bearing component is composed of a frame connecting the support frame and a boss that closes at both ends. The boss is integrally formed at the bottom of the frame. The inner circle of the frame surrounds the outer side of the inner circle of the boss. A small load-bearing component is placed on the boss. The structure of the small load-bearing component is the same as that of the large load-bearing component. The two frames of the small load-bearing component and the large load-bearing component are coplanar.

[0005] Preferably, notches are provided at the four inner corners of the frame.

[0006] Preferably, the support frame consists of an equal number of fixed cylinders and hydraulic dampers. There are four fixed cylinders in a square shape, which are fixed to the bottom of the frame of the large bearing component. The piston rod of the hydraulic damper is inserted into the corresponding fixed cylinder. The fixed cylinder is also screwed with an A bolt to lock the piston rod.

[0007] Preferably, it also includes a cross-shaped connecting rod for fixing the cylinders of the four hydraulic dampers into one piece.

[0008] Preferably, a clamping block is fixed to the end of the connecting rod, and a through hole is provided on the clamping block. The axis of the through hole is perpendicular to the plane where the connecting rod is located. An expansion joint is also provided on the clamping block, and the expansion joint communicates with the through hole. The expansion joint is opened by inserting the cylinder into the through hole. A B bolt is screwed on the clamping block, and the B bolt is used to narrow the expansion joint.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Place the support frame on the pressure plate of the lower mold corresponding to the upper mold that needs to be replaced. Adjust the gap between the upper and lower molds to make the pressure plate of the upper mold and the frame fit together completely. Then, remove the bolts of the pressure plate of the upper mold so that the upper mold can be removed and suspended on the bracket by the cooperation of the frame and the pressure plate. Then, remove it and replace it with a new upper mold. The structure is simple and easy to operate, which improves the efficiency of mold changing. At the same time, the cooperation of large and small load-bearing components can be used for pressure plates of upper molds of various specifications and sizes, thus expanding the scope of application.

[0019] like Figure 1 As shown, a hydraulic arm shock-absorbing mold-changing frame includes a support frame with a large load-bearing component mounted on it. The large load-bearing component consists of a frame 1 connecting the support frame and a closed boss 2. The boss 2 is integrally formed at the bottom of the frame 1, with the inner ring of the frame 1 surrounding the outer side of the inner ring of the boss 2. A small load-bearing component is placed on the boss 2. The structure of the small load-bearing component is the same as that of the large load-bearing component. The two frames 1 of the small and large load-bearing components are coplanar (to avoid the small load-bearing component protruding and reducing the gap between the upper mold and the frame 1, ensuring...). With sufficient operating space, the support frame is placed on the pressure plate of the lower mold corresponding to the upper mold that needs to be replaced. The gap between the upper and lower molds is adjusted so that the pressure plate of the upper mold and the frame 1 are completely fitted. Then the bolts of the pressure plate of the upper mold are removed so that the upper mold is suspended on the bracket by the cooperation of the frame 1 and the pressure plate after removal. Then it is taken out and replaced with a new upper mold. The structure is simple and easy to operate, which improves the efficiency of mold replacement. At the same time, the cooperation of large and small load-bearing components can be adapted to the use of pressure plates of upper molds of various specifications and sizes, thus expanding the scope of application.

[0020] In this embodiment, as Figure 1 As shown, notches 3 are provided at the four inner corners of the frame 1 to facilitate the removal of small carrier parts by inserting fingers.

[0021] In this embodiment, as Figure 1 As shown, the support frame consists of an equal number of fixed cylinders 4 and hydraulic buffers 5. There are four fixed cylinders 4, which are square and fixed to the bottom of the frame 1 of the large load-bearing component. The piston rod of the hydraulic buffer 5 is inserted into the corresponding fixed cylinder 4. The fixed cylinder 4 is also screwed with A bolts 6 to lock the piston rod (for easy replacement after damage). After the upper mold falls off, the hydraulic buffer 5 is pressed down, so that the upper mold is completely separated from the fixing bolt, avoiding interference from the fixing bolt and affecting the removal of the upper mold.

[0022] In this embodiment, as Figure 1 As shown, it also includes a cross-shaped connecting rod 7, which is used to fix the cylinders of the four hydraulic dampers 5 into one piece, enhancing the stability of the support frame and preventing the upper mold from overturning after falling due to individual tilting.

[0023] In this embodiment, as Figure 1 As shown, a clamping block 8 is fixed to the end of the connecting rod 7. A through hole is provided on the clamping block 8, and the axis of the through hole is perpendicular to the plane where the connecting rod 7 is located. An expansion slot 9 is also provided on the clamping block 8, which is connected to the through hole. The expansion slot 9 is expanded by inserting the cylinder into the through hole. A B bolt 10 is screwed onto the clamping block 8. The B bolt 10 is used to narrow the expansion slot 9 (the clamping block 8 has A through holes that penetrate the two side walls of the expansion slot 9. The A through hole on one side wall is threaded, while the other side wall is not threaded. The B bolt 10 passes through the unthreaded A through hole and is screwed into the threaded A through hole. The expansion slot 9 can be narrowed by screwing the B bolt 10). This allows the height of the connecting rod 7 to be adjusted to avoid protrusions of different heights on the lower mold.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
