[0021] The present invention provides a punching and blanking device for PVC pipe seals, which has the following beneficial effects:

[0022] 1. In the stamping and blanking equipment for the PVC pipe seal, the atomized liquid quickly absorbs heat and vaporizes, so that the molding cavity is quickly cooled down, the molded part is separated from the molding cavity, and the slide moves upward. At this time, the temperature of the punch body is higher, and the covering force of the punch body on the molded part is greater. The molded part moves upward on the surface of the punch body. After the temperature of the punch body is lowered, the material taking mechanism is used to separate the molded part from the punch body. This process uses a secondary cooling method to separate the molded part from the mold, which solves the problem of how to automatically and non-destructively demold the molded PVC pipe seal.

[0023] 2. In the stamping and blanking equipment for the PVC pipe seal, the atomized liquid inside the rubber bag is quickly sprayed into the interior of the concave mold shell, and the molding cavity is quickly cooled down, so that the outer surface of the molded part is quickly cooled down and separated from the molding cavity. Since the molded part is made of plastic material, the heat dissipation performance is poor, and the inner surface of the molded part is still covered with the punch body. After the punch body moves upward, the molded part is cooled down, thereby facilitating the demoulding and blanking of the molded part.

[0024] 3. In the stamping and blanking equipment for the PVC pipe seal, the guide pipe introduces cooling water into the interior of the flip shell, and the inner and outer surfaces of the molded part are completely cooled. The first screw slide drives the scraper assembly to extend to the position just above the punch body, and the slide plate moves upward. The molded part on the surface of the punch body is scraped off by the scraper assembly, and the scraper assembly conveys multiple molded parts. The motor drives the scraper assembly to flip 180 degrees, and the molded parts are guided out for blanking, which solves the problem of how to convey and blank the PVC pipe seal after demolding.

[0025] 4. The stamping and blanking equipment for the PVC pipe seal, after the punch body is driven to flip 180 degrees, the first screw slide drives the support shell to move to the position directly above the punch body, and the molded parts are scraped into the inside of the support shell. The support shell stores multiple molded parts. After the support shell slides outward, the motor drives the support shell to flip 180 degrees, and the guide rail rotates and supports the connecting rod. Multiple molded parts are quickly blanked, thereby making the stamping efficiency of the PVC pipe seal higher.

[0026] 5. In the stamping and blanking equipment for the PVC pipe seal, the punch body is driven upward by the slide plate, the top of the punch body passes through the through hole, the thin narrow plate is arranged relative to the extended edge of the molded part, and the telescopic rod drives the oppositely arranged thin narrow plates to move relatively close, and the thin narrow plates are embedded in the extended edge of the molded part. At this time, the molded part has been completely cooled, and the surface of the molded part is pried off the punch body and falls into the inside of the supporting shell. The molded part does not need to be demolded by impact using a push rod, and there is no need to set a push rod hole, so that the molded surface of the PVC pipe seal is smoother.

[0044] When in use, the interior of the molding cavity 53 is filled with a mixture of plastic particles and rubber particles, the opening and closing machine 4 drives the slide plate 61 to move downward, the support seat 3 slides and supports the movement of the slide plate 61, and the male mold body 64 falls vertically into the interior of the molding cavity 53, and the guide pipe 65 passes heating oil into the interior of the flip shell 63, and the mixed granular material is heated and pressurized to form a PVC pipe seal. Subsequently, the heating oil in the female mold shell 51 is discharged, and the quick cooling component 55 passes easily evaporable atomized liquid into the interior of the female mold shell 51. The atomized liquid quickly absorbs heat and vaporizes, so that the molding cavity 53 is quickly cooled down, the molded part is separated from the molding cavity 53, and the slide plate 61 moves upward. At this time, the temperature of the male mold body 64 is relatively high, and the male mold body 64 has a greater covering force on the molded part. The molded part moves upward on the surface of the male mold body 64. After the temperature of the male mold body 64 is reduced, the material taking mechanism 7 is used to separate the molded part from the male mold body 64. This process uses a secondary cooling method to separate the molded part from the mold, which solves the problem of how to automatically and non-destructively demold the molded PVC pipe seal.

At this time, the pressure valve 553 is in a closed state. The air pressure inside the rubber bag 552 gradually increases until it reaches the threshold of the pressure valve 553.

The condensation tube 554 re-introduces the condensed liquid into the interior of the atomizing pump 551. The molding cavity 53 is quickly cooled down, so that the outer surface of the molded part is quickly cooled down and separated from the molding cavity 53. Since the molded part is made of plastic material and has poor heat dissipation performance, the inner surface of the molded part is still covered with the punch body 64.
