Therefore, MOS tube is sometimes called insulated gate field effect tube. In general electronic circuits, MOS tubes are usually used in amplifier circuits or switching circuits.

[0003] During the production of existing MOS tubes, shaping equipment is required for processing. The MOS tube shaping mold is a tool specifically used to trim and shape the MOS tube. Since the equipment needs to be replaced according to different requirements during use, the shaping mold needs to be replaced. However, the existing MOS tube shaping mold requires the removal of multiple screws and nuts when replacing, which is not convenient, resulting in the problem that the mold cannot be changed quickly.

[0008] As a further solution of the present invention: the upper surface and the bottom surface of the fixed shell are fixedly connected to two connecting blocks, and the interior of each connecting block is slidably connected to a fixing pin.

[0009] As a further solution of the present invention: a protective pad is fixedly connected to the back of the fixed shell, and the protective pad needs to be in the shape of soft rubber.

[0010] As a further solution of the present invention: the inner wall of each installation opening is fixedly connected to two guide plates, and the side surfaces of each group of guide plates close to each other are in contact with the front and back surfaces of the limiting frame.

[0011] As a further solution of the present invention: the side surfaces of the two limiting frames that are away from each other are fixedly connected with a fixing ring, and the inner wall of each fixing ring is fixedly connected to the outer surface of the connecting rod.

[0012] As a further solution of the present invention: the outer surface of each telescopic spring is fixedly connected to a reinforcement plate, and the side surfaces of the two groups of reinforcement plates that are close to each other are fixedly connected to the side surfaces of the two limit frames that are away from each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model is provided with a fixed shell that can be first installed on the equipment, and the shape of the clamping plate is matched with the shape of the mold so that it can be directly pressed into the fixed shell. At the same time, the shape of the clamping plate is matched with the shape of the limit frame, and the two limit frames can be pressed into the interior of the sliding shell by the mold and the clamping plate. When the limit frames slide, the telescopic spring is compressed so that the telescopic spring has elastic force. When the clamping plate and the mold reach the interior of the fixed shell, the shape of the mold and the elastic force of the telescopic spring push the limit frames into the interior of the mold, so that the fixed shell fixes the mold inside for use. Then, by moving the connecting rod, the limit frames can be driven to move away from each other, so that the mold and the clamping plate can be conveniently taken out of the fixed shell, so that the mold can be quickly replaced when shaping the MOS tube.

[0023] Specifically, the upper surface and the bottom surface of the fixed shell 1 are fixedly connected to two connecting blocks 4 , and the interior of each connecting block 4 is slidably connected to a fixing pin 3 .

[0024] Through the above technical solution, the connection block 4 is provided to be connected to the fixed shell 1, and the connection block 4 can be fixed by using the fixing pin 3, so that the fixed shell 1 can be fixed for use.

[0025] Specifically, a protective pad 6 is fixedly connected to the back of the fixed shell 1 , and the protective pad 6 needs to be in a soft rubber shape.

[0026] Through the above technical solution, by providing the protective pad 6, it can play a protective role when the fixed shell 1 is fixedly connected due to its own characteristics.

[0027] Specifically, two guide plates 9 are fixedly connected to the inner wall of each installation opening 15 , and the side surfaces of each set of guide plates 9 that are close to each other are in contact with the front and back surfaces of the limiting frame 7 .

[0028] Through the above technical solution, by providing the guide plate 9, the limiting frame 7 can be limited, so that the limiting frame 7 has stability when sliding.

[0029] Specifically, a fixing ring 11 is fixedly connected to the side surfaces of the two limiting frames 7 that are away from each other, and the inner wall of each fixing ring 11 is fixedly connected to the outer surface of the connecting rod 14 .

[0030] Through the above technical solution, by providing the fixing ring 11, the limiting frame 7 can be connected to the connecting rod 14, and then the connecting rod 14 can drive the limiting frame 7 to move.

[0031] Specifically, the outer surface of each telescopic spring 13 is fixedly connected to a reinforcement plate 12 , and the sides of the two groups of reinforcement plates 12 that are close to each other are fixedly connected to the sides of the two limiting frames 7 that are away from each other.

[0035] The working principle of the utility model is as follows: when in use, first, the fixed shell is placed on the MOS tube shaping device, and the connecting block is penetrated and fixed on the MOS tube shaping device by the fixing pin shaft. When the fixing is completed and used, the mold and the card plate are moved to the opening of the fixed shell, and then the mold and the card plate are pushed into the interior of the fixed shell. When the mold and the card plate are pushed into the interior of the fixed shell, the limit frame is squeezed by the shape of the card plate and the limit frame, and at the same time, the limit frame is moved into the interior of the sliding shell. When the limit frame moves, the telescopic spring is compressed. When the limit frame moves to be level with the sliding shell, the mold and the card plate are moved into the interior of the fixed shell and through The opening of the mold allows the limit frame to move to the inside of the mold through the elastic force of the telescopic spring, thereby limiting the mold and the card plate in the fixed shell, and starting the MOS tube shaping equipment. When the mold needs to be replaced, the staff uses the connecting frame and the handle to pull the two connecting rods away from each other. Through the movement of the connecting rods, the limit frame is driven to slide toward the inside of the sliding shell again and compress the telescopic spring. When the limit frame is level with the sliding shell again, the mold can be removed from the fixed shell, and then the force on the connecting rod is released. At this time, the limit frame is pushed back to its original position by the elastic force of the telescopic spring, further enabling the MOS tube shaping to quickly replace the mold.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
