[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-2 A plastic mold that can be quickly demolded includes a bottom mold 1 and a top mold 2. A mounting plate 3 is provided on one side of the bottom mold 1, and a mounting plate 2 4 is provided on one side of the top mold 2. A demolding rod 5 is fixed on the mounting plate 3, and a demolding groove 6 adapted to the demolding rod 5 is opened on the bottom mold 1.

[0021] An air supply assembly is provided on the mounting plate 24, and the air supply assembly includes a sealing box 71, a slide plate 72, a spring 73, a pressure block 74 and an air pipe 75. The sealing box 71 is fixed to the side of the mounting plate 24, and the slide plate 72 is sealingly slidably connected to the inner surface of the sealing box 71. One end of the spring 73 is connected to the inner surface of the sealing box 71, and the other end is connected to the slide plate 72. The pressure block 74 is fixed on the slide plate 72, and the pressure block 74 extends to the outside of the sealing box 71. The pressure block 74 is arranged opposite to the top mold 2. One end of the air pipe 75 is connected to the sealing box 71. The air pipe 75 is Using a hose, after the injection molding is completed, the top mold 2 is first separated from the bottom mold 1. At this time, the top mold 2 moves toward the direction close to the mounting plate 4. During this process, the top mold 2 will squeeze the pressure block 74, so that the pressure block 74 drives the slide plate 72 to move. The slide plate 72 can squeeze the air in the mounting box 71 during the movement in the sealing box 71. Since the demolding rod 5 is located inside the demolding groove 6 at this time, the demolding groove 6 blocks the plurality of air jet holes 82, and the gas cannot be ejected through the plurality of air jet holes 82, so the air pressure between the sealing box 71 and the slide plate 72 will increase.

[0022] The demolding rod 5 is provided with an injection assembly, which includes a cavity 81 and a plurality of injection ports 82. The cavity 81 is opened inside the demolding rod 5, and the plurality of injection ports 82 are all opened on the outer peripheral surface of the demolding rod 5, and the plurality of injection ports 82 are all connected with the cavity 81. The plurality of injection ports 82 are evenly distributed on the demolding rod 5, and the cavity 81 is connected with the other end of the air pipe 75. When the demolding rod 5 moves out of the demolding groove 6, the plurality of injection ports 82 will be exposed. At this time, the compressed gas in the sealing box 71 will be ejected through the plurality of injection ports 82, so as to perform a blowing and demolding method on the finished product.

[0023] The specific working principle of the utility model is as follows:

[0024] During the use of the plastic mold proposed by the utility model, after the injection molding is completed, the top mold 2 is first separated from the bottom mold 1. At this time, the top mold 2 moves toward the direction close to the mounting plate 4. In this process, the top mold 2 will squeeze the pressure block 74, so that the pressure block 74 drives the slide plate 72 to move. The slide plate 72 can squeeze the air in the mounting box 71 during the movement in the sealing box 71. Since the demolding rod 5 is located inside the demolding groove 6 at this time, the demolding groove 6 blocks the plurality of air injection holes 82, and the gas cannot be ejected through the plurality of air injection holes 82, so the air pressure between the sealing box 71 and the slide plate 72 will increase. Further, the bottom mold 1 moves toward the mounting plate 4. The mold assembly 70 moves in the direction of -3. During this process, the demoulding rod 5 can move out of the demoulding groove 6 and eject the finished product on the bottom mold 1. In addition, when the demoulding rod 5 moves out of the demoulding groove 6, a number of air jets 82 will be exposed. At this time, the compressed gas in the sealing box 71 will be ejected through the air jets 82, which plays a role in blowing and demoulding the finished product. Based on the above process, the plastic mold proposed by the utility model combines the ejection demoulding and blowing demoulding methods, which can improve the demoulding effect and demoulding efficiency. In addition, the generation of gas does not require a gas source. The gas can be provided by using the gas supply component in conjunction with the movement of the top mold 2, thereby reducing the use cost of the mold.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
