Description

Technical Field

[0001] The present invention relates to the technical field of demoulding, and more particularly to an automatic demoulding and blanking structure for a hydraulic press. Background Art

[0002] Blister products are products made from plastic sheets through the blister process. The blister process, also known as vacuum forming or compression forming, is a plastic processing method that uses heated and softened plastic sheets to be adsorbed to the mold surface under vacuum and heated to a certain temperature. The mold is then closed to cool and solidify to form the desired plastic product. In order to obtain qualified blister products, the blister products need to be punched and sheared.

[0003] In the prior art, when punching and shearing blister products, the punching and shearing is mostly performed directly through the upper and lower molds. However, the blister products are easily displaced during the punching and shearing process, resulting in the punched and sheared blister products not meeting the requirements. In severe cases, the blister products are directly scrapped and the qualified rate of the finished products is low. At the same time, the waste of the blister products after the punching and shearing process is difficult to clean, and the finished products are not easy to take out, which reduces the practicality of the punching and shearing molds. Summary of the Invention

[0023] When the upper mold 2 moves downward, the guide rod 5 of the guide plate 4 moves in the guide groove 7 of the guide frame 6 to limit the movement direction of the upper mold 2. Before the upper mold 2 contacts the lower mold 3, the pressing plate 15 first contacts the edge of the blister product on the lower mold 3 and presses the edge of the blister product. The pressing plate 15 squeezes the pressing spring 16 through the pressing rod 14 and the movable plate 13. At the same time, the elastic force of the pressing spring 16 gives the pressing plate 15 a greater elastic force, and cooperates with the rubber pad 17 to ensure that the pressing plate 15 stably presses the edge of the blister product. When the punching head 8 cooperates with the punching groove 9 for punching and shearing, the pressing plate 15 moves into the pressing groove 18, and the blister product moves into the discharge groove 10 after being processed by the punching head 8, thereby realizing precise punching and shearing operation of the blister product.

[0024] See also Figure 4-5 , as an implementation method of the mold body 1: a cleaning plate 19 is provided on the lower mold 3, a blanking plate 20 is provided in the blanking trough 10, a sliding block 21 is symmetrically provided on the cleaning plate 19, and a sliding groove 22 cooperating with the sliding block 21 is provided on the lower mold 3.

[0025] More specifically, when fixing the position of the lower mold 3, the electromagnetic column 29 is energized by the battery 30, and the electromagnetic column 29 is extended into the limiting hole 28 of the limiting plate 26 and the metal plate 27, thereby fixing the position of the mold body 1. After the punching and shearing is completed, the driving cylinder 23 is started, and the driving cylinder 23 contracts to drive the driving plate 24 and the driving rod 25 to move. The cleaning plate 19 cleans the waste on the lower mold 3, and the blanking plate 20 pushes the finished blister products in the blanking trough 10 to facilitate blanking.

[0026] In summary, when the overall equipment is in use or running: the application scenario of the punching and shearing mold in this application is a punching and shearing machine, and the punching and shearing machine structure adopts the existing technology. The blister product is placed on the lower mold 3, and the driving mechanism of the punching and shearing machine drives the upper mold 2 to move downward. During the downward movement of the upper mold 2, the guide rod 5 of the guide plate 4 moves in the guide groove 7 of the guide frame 6 to limit the moving direction of the upper mold 2. Before the upper mold 2 contacts the lower mold 3, the pressing plate 15 first contacts the edge of the blister product on the lower mold 3. The edge of the blister product is pressed, and the pressing plate 15 squeezes the pressing spring 16 through the pressing rod 14 and the movable plate 13. At the same time, the elastic force of the pressing spring 16 gives the pressing plate 15 a greater elastic force, and cooperates with the rubber pad 17 to make the pressing plate 15 stably press the edge of the blister product. When the punching head 8 and the punching groove 9 cooperate to perform punching and shearing, the pressing plate 15 moves to the pressing groove 18, and the blister product moves to the unloading chute 10 after being processed by the punching head 8, thereby realizing the precise punching and shearing operation of the blister product.

[0027] When fixing the position of the lower mold 3, the electromagnetic column 29 is energized by the battery 30, and the electromagnetic column 29 is extended into the limiting hole 28 of the limiting plate 26 and the metal plate 27, thereby fixing the position of the mold body 1. After the punching and shearing is completed, the driving cylinder 23 is started, and the driving cylinder 23 contracts to drive the driving plate 24 and the driving rod 25 to move. The cleaning plate 19 cleans the waste on the lower mold 3, and the blanking plate 20 pushes the finished blister products in the blanking trough 10 to facilitate blanking.
