Description

Die opening device of interference fit die Technical Field The utility model belongs to the technical field of mold opening devices, and particularly relates to a mold opening device of an interference fit mold. Background The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. The existing die opening device can meet the basic requirements of die opening and die separation of an upper die and a lower die of an interference fit die, but the existing die opening device adopts a V-shaped chisel to be matched with hammers of different sizes for manual die opening, namely, one person holds the chisel and the other person swings the hammer, transverse force is generated through the V-shaped angle of the chisel, and the upper die (male die) and the lower die (female die) of the interference fit are forced to be separated. In the process of striking the chisel by the hammer, scrap iron is easy to splash and hurt human body due to metal collision, and noise generated in the striking process is very harsher, and meanwhile, the parts such as hands are easy to be hurt due to errors of operators in the striking process, so that industrial accidents are generated. Disclosure of utility model In view of the above, the utility model provides a die opening device for an interference fit die, which can meet the basic requirement of die opening, and has the characteristics of convenient operation, high processing efficiency and high safety. In order to solve the technical problems, the technical scheme includes that the die opening device of the interference fit die comprises a fixed support, a sliding trolley is arranged at the bottom of the fixed support in a sliding mode, the die is rotatably arranged on the sliding trolley, a first telescopic push rod is arranged at the top of the fixed support, a mounting frame is arranged at the lower end of an output shaft of the first telescopic push rod, and a die opening tool for opening the die is rotatably arranged in the mounting frame. The vertical section of the die opening cutter is diamond. The V-shaped die opening cutter is suitable for dies with various shapes, in particular to an interference fit die. As a further improvement of the utility model, one side of the bottom of the fixed support is provided with a second telescopic push rod, an output shaft of the second telescopic push rod is connected with the sliding trolley, and the bottom of the sliding trolley is in sliding connection with the bottom of the fixed support. As a further improvement of the utility model, a transmission roller way for supporting and rotationally driving the die is rotationally arranged on the sliding trolley, a containing groove for containing the die is formed on the transmission roller way, the axial length of the containing groove is greater than that of the die, and the transmission roller ways are rotationally connected through a chain and a chain wheel. As a further improvement of the utility model, the placing frame is provided with a driving motor, and the driving motor is rotationally connected with a transmission roller way through a gear transmission assembly. As a further improvement of the utility model, the vertical section of the die-sinking tool is diamond-shaped. As a further development of the utility model, the die-sinking tool is rotatably connected to the mounting frame. The die-opening tool can be prevented from being easily damaged. As a further development of the utility model, the first telescopic ram is a hydraulic telescopic ram. The die opening tool can be effectively driven, and the die opening can be more remarkably performed. As a further improvement of the utility model, the side end of the mounting frame is also provided with a guide plate which is vertically and slidably connected with the side end of the fixed bracket, and the guide plate is provided with a guide sliding hole which is slidably connected with the side end of the fixed bracket. Through the cooperation of deflector and direction slide hole, can make the die sinking cutter vertical movement steadily to avoid the die sinking cutter to take place the skew easily at the in-process of work, and avoid first flexible push rod to receive non-vertical effort and deform impaired easily. As a further improvement of the utility model, the mounting frame is also rotatably provided with a compression wheel for limiting the die. Through the pinch roller, can avoid the vertical skew of mould for the mould keeps stable at the in-process of die sinking. Compared with the prior art, the utility model has the following beneficial effects: The first telescopic push rod (hydraulic telescopic rod) drives the V-shaped die opening cutter to move up and down, and die opening is completed. Secondly, through holding the recess, can avoid the mould to directly follow the roll tab
