Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding processing, in particular to an extrusion and plastic suction molding integrated machine. Background Art

[0002] Vacuum forming is also called thermoplastic forming. This forming process mainly uses the vacuum suction generated by a vacuum pump to soften the thermoplastic plastic sheet after heating, and uses the vacuum or pressure of the mold to deform the sheet to achieve the required shape and size, and is supplemented by supporting procedures to achieve the application purpose. Before vacuum forming, it also needs to be extruded, so the corresponding extrusion and vacuum forming equipment is required.

[0003] At present, extrusion and vacuum forming equipment can better utilize sheet workpieces. Usually, such equipment is divided into two parts: extrusion equipment and vacuum forming equipment. The extrusion process must be carried out first, and the sheet raw materials are transported to the mold of the vacuum forming equipment through a transportation device, and then the vacuum forming process is carried out. The above method makes it difficult for the processing efficiency to reach the established expectations, which often troubles people. Utility Model Content

[0030] Among them, a guide rod 11 is fixed on the side of the right template 4 away from the left template 3. Two guide rods 11 are provided in the up and down directions. A piston rod 12 is provided between the two guide rods 11. One end of the piston rod 12 is fixed on the right template 4, and the other end is connected to a cylinder 13.

A resistance rod 23 is fixed to the end of the spring 22 away from the trigger rod 21. The two travel switches 20 are electrically connected to the servo motor 19.

[0034] During the extension process of the guide rod 11, as the contact rod 23 contacts the travel switch 20, the contact rod 23 can close the travel switch 20, and then the travel switch 20 turns on the servo motor 19. After the servo motor 19 is driven, the gear 16 is driven to rotate, and then the rack 15 moves downward under the rotation drive of the gear 16, driving the fixed rod 9 and the blister plate 8 to move downward to the position below the fixed frame 2, and as the guide rod 11 continues to move, the contact rod 23 can contact the second travel switch 20 to turn off the servo motor 19.

[0038] The working principle of the utility model is as follows: during injection molding, the cylinder 13 is turned on to drive the right template 4 to move toward the left template 3, and injection molding is performed after the fitting. While the right template 4 moves, the abutment rod 23 on the guide rod 11 contacts the travel switch 20, and the servo motor 19 is turned on to drive the blister plate 8 to move downward. After the blister plate 8 is completely stored, the servo motor 19 is turned off.
