[0024] Two blocks 5 are provided on the top surface of the machine body 6, and lock holes 13 are provided on the surfaces of the two blocks 5. A base 4 is provided on the top of the machine body 6. The upper mold 2 and the lower mold 3 are installed on two mounting frames 1 on the top surface of the base 4. During installation, the various components are correctly connected and stability and flatness are ensured. The guide pillars and guide sleeves and other components are installed at predetermined positions and adjusted to appropriate gaps. The molding components are added: The molding components are the parts of the mold that directly determine the shape of the product. According to the shape and size of the product, the appropriate molding components (such as upper mold, lower mold, insert, etc.) are selected and installed at the corresponding positions. Two locking tongues 11 are provided inside the base 4, and one of the locking tongues 11 The ends of the two locking tongues 11 penetrate the base 4 and enter the interior of the card slot 8. An oblique tongue spring 14 is provided between the two locking tongues 11 and the base 4. A connecting rod 9 is provided on the top of the two locking tongues 11. The connecting rod 9 is "L" shaped. One end of the connecting rod 9 penetrates the base 4 and penetrates into the interior of the button 7 to be connected with the damper 10. When installing, it is only necessary to correctly connect and install the various components of the upper mold 2 and the lower mold 3 on the mounting frame 1 of the base 4, so that the upper mold 2 and the lower mold 3 are presented as a whole. When installed, align the card slot 8 of the base 4 with the card block 5 of the body 6, and put the base 4 on the body 6. When it is put on, the card block 5 on the top surface of the body 6 will knock open the inside of the card slot 8 The locking tongue 11 is retracted into the interior of the base 4. When the base 4 continues to descend and the locking tongue 11 encounters the lock hole 13, the locking tongue 11 will be pushed out by the oblique tongue spring 14, so that the locking tongue 11 is stuck in the lock hole 13. When the locking tongue 11 is pushed out by the oblique tongue spring 14, the part of the locking tongue 11 connected to the connecting rod 9 at the end is larger than the part of the locking tongue 11 inside the oblique tongue spring 14. In this way, the locking tongue 11 will be stuck when it is positioned, so that the base 4 is installed on the body 6. When disassembling, press the buttons 7 on both sides of the base 4. When the button 7 is pressed, the button 7 will move to the side of the base 4 because one end of the connecting rod 9 is connected to the resistance inside the button 7. The button 7 is connected to the diaphragm 10, and the other end is connected to the lock tongue 11. When the button 7 moves toward the side of the base 4, the connecting rod 9 will be driven to move together. Because the connecting rod 9 is connected to the lock tongue 11, when the button 7 moves, the lock tongue 11 will be driven to move together, so that the lock tongue 11 will be disengaged from the lock hole 13 of the block 5. Since the end of the button 7 close to the base 4 is provided with a thread, the button 7 can be rotated at this time so that the button 7 is installed in the fixing hole 12 through the cooperation of the thread to complete the fixation. At this time, the base 4 can be disassembled. Since the upper mold 2 and the lower mold 3 are both installed on the mounting frame 1 on the top surface of the base 4 as an integral whole, the integrated mold can be quickly replaced. Specific embodiment 2:

[0026] Reference Figure 1-4A fixture can be provided at the bottom of the base 4, and the lock tongue 11, the oblique tongue spring 14 and the connecting rod 9 are all set inside the fixture, and one end of the connecting rod 9 passes through the fixture and passes through the button 7 and the damper 10 inside the button 7 for welding. A fixing frame and a threaded hole are provided on both sides of the fixture, and the fixing frame is installed on the fixture, and the threaded hole is set on the base 4. The threaded hole is consistent with the position of the fixing frame. A fixing bolt is provided on one side of the fixing frame, and the fixing bolt passes through the fixing frame and is installed in the threaded hole. The fixing bolt is rotated so that the fixing bolt is installed in the threaded hole, so that the fixture is installed on the base 4. When the lock tongue 11, the oblique tongue spring 14 and the connecting rod 9 inside the fixture are damaged, the fixture can be directly replaced.

[0027] In summary:

[0028] 1. The top surface of the machine body 6 is provided with two card blocks 5, and the middle of the two card blocks 5 is provided with a lock hole 13. A base 4 is provided on the top of the machine body 6. The upper mold 2 and the lower mold 3 are installed on two mounting frames 1 on the top surface of the base 4. Two locking tongues 11 are provided inside the base 4, and one end of the locking tongue 11 penetrates the base 4 and penetrates into the card slot 8. An oblique tongue spring 14 is provided between the two locking tongues 11 and the base 4. A connecting rod 9 is provided on the top of the two locking tongues 11, and one end of the connecting rod 9 penetrates the base 4 and penetrates into the card slot 8. The interior of the button 7 is connected to the damper 10. When installing, it is only necessary to install the upper mold 2 and the lower mold 3 on the mounting frame 1 of the base 4 so that the upper mold 2 and the lower mold 3 are presented as a whole. When installed, align the card slot 8 of the base 4 with the card block 5 of the body 6, and place the base 4 on the body 6. When placed, the card block 5 on the top surface of the body 6 will knock open the lock tongue 11 inside the card slot 8, so that the lock tongue 11 is retracted into the inside of the base 4. When the base 4 continues to descend and the lock tongue 11 encounters the lock hole 13, the lock tongue 11 will be The oblique tongue spring 14 is pushed out, so that the lock tongue 11 is stuck in the lock hole 13, so that the base 4 is installed on the body 6. When disassembling, press the buttons 7 on both sides of the base 4. When the button 7 is pressed, the button 7 will move to the side of the base 4. Because one end of the connecting rod 9 is connected to the damper 10 inside the button 7, and the other end is connected to the lock tongue 11, when the button 7 moves to the side of the base 4, it will drive the connecting rod 9 to move together. Because the connecting rod 9 is connected to the lock tongue 11, when the button 7 moves, it will drive the lock tongue 11 to move together, so that the lock tongue 11 is separated from the lock hole 13 of the block 5. Since the button 7 is provided with a thread at one end close to the base 4, the button 7 can be rotated at this time, so that the button 7 is installed in the fixing hole 12 through the cooperation of the thread to complete the fixation. At this time, the base 4 can be disassembled. Since the upper mold 2 and the lower mold 3 are both installed on the mounting frame 1 on the top surface of the base 4 as an integrated whole, the rapid replacement of the integrated mold is completed, which solves the disadvantage that the upper mold 2 and the lower mold 3 cannot be quickly replaced as a whole.
