[0020] The present invention provides a double-layer blister shell processing equipment and a processing technology thereof. It has the following beneficial effects:

[0021] (1) The invention utilizes the rising sealing plate to push the gas inside the air pipe to be ejected. The gas ejected from the bottom of the processed mold can improve the demoulding effect and prevent the mold from adhering to the lower mold and affecting the removal of the mold. At the same time, the top of the air pipe is blocked by the sealing circular plate to prevent the air pipe from being in an open device during stamping, resulting in defects in the stamped mold and affecting the stamping effect.

[0022] (2) In the present invention, the movement of the L-shaped short rod toward the sliding block will push the sliding block upward, and the upward movement of the sliding block will release the limit on the impact plate, so that the impact plate can be reset by the elastic force of the spring itself. The impact plate will then hit the lower mold when it is reset, and the demoulding effect will be improved by the impact. At the same time, when the elastic telescopic rod is reset, it will squeeze the gas inside the air pressure box to eject it, and the ejected gas will be used to blow away impurities on the plastic plate before stamping, so as to prevent the impurities from adhering to the plastic plate and affecting the stamping effect.

[0023] (3) The invention pushes the triangular slider upward through the connecting rod. The upward movement of the triangular slider will drive the limit plate to move upward. The upward movement of the limit plate will limit the observation door to prevent the staff from opening the observation door during stamping, which may cause accidents and pose a safety hazard. At the same time, the upward rotation of the L-shaped block will drive the shaft to rotate upward. The upward rotation of the shaft will drive the brush rod to move upward. The brush rod is used to rotate upward to scrape the inner wall of the observation door to prevent the high-temperature gas generated during stamping from blurring the observation door and making it impossible to observe the stamping situation through the observation door. When an accident occurs, the equipment cannot be closed in time, affecting the use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

7. The double-layer blister shell processing equipment according to claim 6, characterized in that: An L-shaped rod (19) is fixedly mounted on the surface of the slide plate (18), and an arc-shaped plate (20) is slidably mounted on the inner wall of the air pipe (8), wherein the arc-shaped plate (20) is arranged above the L-shaped rod (19).

8. The processing technology of the double-layer blister shell processing equipment according to claim 7 is characterized in that: The following steps are involved: Step 1: The hydraulic device (4) moves downward to drive the upper mold (5) to move downward, and the plastic plate on the lower mold (6) is stamped and formed by the downward movement of the upper mold (5); Step 2: The sealing plate (9) is driven to rise by the connection plate (7), and the rising sealing plate (9) is used to push the gas inside the air pipe (8) to be ejected. The gas is ejected from the bottom of the processed mold to improve the demoulding effect and prevent the mold from being attached to the lower mold (6), which affects the removal of the mold; Step 3: The slide plate (18) is moved upward to drive the L-shaped slide bar (17) to move upward, and the L-shaped slide bar (17) is moved upward to drive the sealing circular plate to move upward, and the top of the air pipe (8) is blocked by the sealing circular plate to prevent the air pipe (8) from being in an open position during stamping, resulting in defects in the stamped mold and affecting the stamping effect; Step 4: The slide plate (18) moves downward, and the slide plate (18) drives the L-shaped rod (19) to move downward. The L-shaped rod (19) moves downward and is separated from the support of the arc plate (20). The arc plate (20) is reset to seal the air inlet pipe (15), so as to prevent the sealing plate (9) from squeezing the gas out through the air inlet pipe (15), thereby affecting the demoulding effect.
