Specifically, the material receiving device 55 includes a sliding plate 551 and a pulling plate 553, the sliding plate 551 is slidably mounted on the inner wall of the supporting frame 1, one end of the sliding plate 551 penetrates through the supporting frame 1 and is fixedly connected with the connecting plate 51, so that the connecting plate 51 can move up and down, a folding rod 552 is fixedly mounted on the sliding plate 551, when the folding rod 552 moves upwards for a certain distance, the top end of the folding rod 552 can contact with an inclined plane on the overturned wedge-shaped block 10, the wedge-shaped block 10 is pushed to the inside of the lower die plate 3 through the inclined plane, and then the plastic plate can automatically move downwards under the action of self gravity and fall on the conveying belt 54. The pull plate 553 is fixedly installed on the guide frame 254, and the pull plate 553 can be driven to move upwards by the movement of the guide frame 254, and can be contacted with the sliding plate 551 after the pull plate 553 moves to a designated position, and the sliding plate 551 is driven to move upwards, so that the conveyer belt 54 and the folding rod 552 can automatically move upwards. When the pull plate 553 moves downward, the sliding plate 551 is automatically reset under the action of self gravity.
Working principle: in a state where the upper die plate 44 and the lower die plate 3 are closed, a molten plastic material is injected into the cavity through the injection pipe 45, and after injection molding is completed, the material in the cavity is cooled by the cooling mechanism 6 and the heat dissipation mechanism 7, so that the material is molded.
Subsequently, the oil cylinder 43 is started, the output end of the oil cylinder 43 contracts, and the upper die plate 44 is driven to move upwards, so that die opening is performed. When the upper die plate 44 is separated from one end of the wedge block 10, the wedge block 10 automatically resets under the elasticity of the supporting spring 11, so that the plastic plate is limited in the lower die plate 3. During the upward movement of the upper template 44, the control board 23 fixedly connected with the upper template is synchronously driven to move upward, and the control board 23 simultaneously drives the positioning pin 22, the driving rack 242 and the guide frame 254 to move upward. During the upward movement of the guide frame 254, the pressure borne by the top of the slide bar 255 is reduced, and at this time, the return spring 256 is stretched under its own elastic force and pushes the support plate 252 to move to one side, so that the support plate 252 is completely separated from the lower die plate 3.
When the positioning pin 22 is withdrawn from the positioning hole in the rotating shaft 21, the driving rack 242 is engaged with the transmission gear 241 and rotates clockwise as the transmission gear 241 moves. The transmission gear 241 drives the lower die plate 3 to rotate clockwise by one hundred eighty degrees through the rotating shaft 21. Then, the pull plate 553 on the guide frame 254 contacts with the sliding plate 551 and drives the sliding plate 551 to move upwards, the sliding plate 551 synchronously drives the connecting plate 51 and the folding rod 552 to move upwards, the connecting plate 51 drives the conveying belt 54 to move upwards through the driving roller 53, and the distance between the conveying belt 54 and the plastic plate is shortened, so that the impact force of the plastic plate falling is reduced. When the folding rod 552 moves upwards for a certain distance, the top end of the folding rod can contact with the inclined plane on the overturned wedge-shaped block 10, and the wedge-shaped block 10 is pushed into the lower template 3 through the inclined plane, so that the plastic plate can automatically move downwards under the action of self gravity and fall on the conveyer belt 54
Since the conveyor belt 54 is made of a flexible material, the impact force applied to the plastic panel can be buffered to prevent the panel from being damaged. The driving motor 52 drives the driving roller 53 to rotate, and then drives the conveying belt 54 to move, so that the falling plastic plate is conveyed to the next process.
