[0006] The fixed mold includes a fixed mold base and a fixed mold core embedded in the fixed mold base; the air supply channel consists of a first channel on the fixed mold base and a second channel on the fixed mold core; the outlet of the first channel and the inlet of the second channel are correspondingly arranged; the outlet of the second channel extends to the cavity where the product needs to be demolded.

[0007] The fixed mold base has a mounting groove in the middle; the fixed mold core is embedded in the mounting groove; the first channel includes a first air inlet extending laterally into the fixed mold base from one side and a second air guide hole communicating vertically with the first air guide hole from the bottom of the mounting groove; the second channel includes a first air blowing hole arranged vertically in the fixed mold core and a second air blowing hole communicating with the first air blowing hole at one end and extending obliquely to the cavity where the product needs to be demolded; the outlet of the second air guide hole is set corresponding to the inlet of the first air blowing hole.

[0008] The moving mold includes a moving mold base and a moving mold core embedded in the moving mold base; the moving mold core is provided with an ejection mechanism for pushing the product off the moving mold core.

[0009] The outlet end of the gas supply channel is shaped like a trumpet.

[0010] The diameter of the first channel is larger than the diameter of the second channel.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model sets up an air supply channel inside the fixed mold, and supplies air to the air supply channel through an external air source, so that the air supply channel forms a gas protective layer at the position where the product needs to be demolded, thereby preventing the surface of the product from being scratched during demolding, thereby improving the production quality of the product.

[0016] (Example 1)

[0017] See Figure 1 This embodiment of a molding die with a gas ejection structure includes a fixed mold 1 and a moving mold 2; the fixed mold 1 and the moving mold 2 are closed to form a product cavity; an air supply channel 3 is provided inside the fixed mold 1 at the cavity where the product needs to be demolded; the air supply channel 3 is connected to an external air source.

[0018] Furthermore, to facilitate the processing of the air supply channel 3, the fixed mold 1 includes a fixed mold base 1-1 and a fixed mold core 1-2 embedded in the fixed mold base 1-1; the air supply channel 3 consists of a first channel 3-1 provided on the fixed mold base 1-1 and a second channel 3-2 provided on the fixed mold core 1-2; the outlet of the first channel 3-1 and the inlet of the second channel 3-2 are correspondingly arranged; the outlet of the second channel 3-2 extends to the cavity where the product needs to be demolded.

[0019] Furthermore, to further facilitate the processing of the air supply channel 3, the fixed mold base 1-1 is provided with a mounting groove in the middle; the fixed mold core 1-2 is embedded in the mounting groove; the first channel 3-1 includes a first air inlet 3-1-1 extending laterally into the fixed mold base 1-1 from one side and a second air guide 3-1-2 communicating vertically with the first air guide hole from the bottom of the mounting groove; the second channel 3-2 includes a first air blowing hole 3-2-1 disposed vertically in the fixed mold core 1-2 and a second air blowing hole 3-2-2 communicating with the first air blowing hole 3-2-1 at one end and extending obliquely to the cavity where the product needs to be demolded; the outlet of the second air guide 3-1-2 is provided corresponding to the inlet of the first air blowing hole 3-2-1.
