[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] As Figure 1 and Figure 2 shown, a plastic cup forming device includes: a blowing mechanism, an extrusion mechanism, and a collection mechanism; the extrusion mechanism includes an upper die 1 and a lower die 2. The extrusion mechanism is used for extruding and forming plastic cups, the blowing mechanism is used for blowing the formed plastic cups towards the collection mechanism, and the collection mechanism is used for collecting the formed plastic cups.

[0026] As Figure 4As shown in the figure, an upper mounting seat 3 is fixedly connected above the upper die 1. A plurality of first through grooves are recessed upward on the bottom surface of the upper die 1. A plurality of first grooves are recessed upward on the bottom surface of the upper mounting seat 3. The first grooves are in one-to-one correspondence and communication with the first through grooves. An upper sleeve 4 is arranged in the first through groove. The top of the upper sleeve 4 extends into the first groove, and its top surface is in contact with the bottom surface of the first groove.

[0027] Preferably, the first through grooves and the first grooves are arranged in a matrix.

[0028] As Figure 2 and Figure 5 As shown in the figure, a cavity is formed above the first groove in the upper mounting seat 3, and an upper bushing 5 is arranged in the cavity. An upper moving shaft 6 is slidably arranged in the upper bushing 5. The upper moving shaft 6 is vertically arranged, and its top end extends above the upper mounting seat 3 and is fixedly connected to an upper connecting plate 23 arranged above the upper mounting seat 3. The bottom end of the upper moving shaft 6 extends into the upper sleeve 4 and is fixedly connected to a cup punch 7 arranged in the upper sleeve 4. The upper connecting plate 23 is connected to a driving mechanism. Under the action of the driving mechanism, the upper moving shaft 6 can move up and down, thereby driving the cup punch 7 to move up and down.

[0029] Among them, a recessed area 15 is formed by recessing the edge of the bottom surface of the upper die 1, and a screw hole is opened in the recessed area 15. The setting of the recessed area 15 makes the middle part of the upper die 1 protrude relative to the edge, which is convenient for docking with the lower die 2. The screw hole is used for fixedly connecting the upper die 1 and the upper mounting seat 3, and the screw hole arranged in the recessed area 15 will not affect the docking of the upper and lower dies. An installation block 16 is fixedly connected to the top surface of the upper mounting seat 3. The installation blocks 16 are distributed on the opposite two edges of the upper mounting seat 3, which are used for connecting the upper mounting seat 3 to the frame, and at the same time, they also have a protective effect on the upper moving shaft 6 in the middle of the upper mounting seat 3.

The second grooves are in one-to-one correspondence and communication with the second through grooves. A lower sleeve 9 is arranged in the second through groove. The top surface of the lower sleeve 9 protrudes above the top surface of the lower die 2 and corresponds to the upper sleeve 4 one by one. During production, the upper and lower sleeves are docked. The bottom end of the lower sleeve 9 extends into the second groove and is fixed in the lower die 2 and the lower mounting seat 8. A cup die 10 is arranged in the lower sleeve 9. Among them, the second through grooves and the second grooves are arranged in a matrix to correspond to the first through grooves and the first grooves.

A lower moving shaft 12 is slidably arranged in the lower bushing 11. The lower moving shaft 12 is vertically arranged, its bottom end is connected to a lower connecting plate 13 arranged below the lower mounting base 8, and its top end is connected to an ejector block 14 arranged inside the cup female die 10. The lower connecting plate 13 is connected to a driving mechanism, and under the action of the driving mechanism, it can drive the lower moving shaft 12 to move up and down, and then drive the ejector block 14 to move up and down to eject the plastic cup formed by extrusion in the cup female die 10.

[0032] Preferably, the edge of the top surface of the lower die 2 is recessed to form a recessed portion 20. The recessed portion 20 makes the middle part of the lower die 2 protrude, which is convenient for docking. The recessed portion 20 corresponds to the recessed area 15. The top surface of the lower die 2 is provided with screw holes for the insertion of screws. A gasket ring 21 is arranged at the top of the screw hole, and the top surface of the gasket ring 21 is flush with the top surface of the lower sleeve 9. The screw holes are arranged in a matrix and are offset from the second through groove. The gasket ring 21 is flush with the top surface of the lower sleeve 9, making the top of the lower die 2 a plane, expanding the contact area between the lower die 2 and the upper die 1, and improving the fixing effect on the plastic sheet during extrusion.

[0033] The bottom of the lower mounting base 8 is provided with a slide bar 22, and the slide bar 22 is slidably connected to the lower connecting plate 13 to improve the stability of the relative sliding of the lower connecting plate 13 with respect to the lower mounting base 8.

[0034] Both ends of the upper mounting base 3 extend beyond both ends of the upper die 1, and positioning protrusions 17 are arranged at the extended parts. Both ends of the lower mounting base 8 extend beyond both ends of the lower die 2, and bumps 18 are arranged at the extended parts. A positioning groove 19 is arranged on the top surface of the bump 18. The positioning protrusion 17 corresponds to the positioning groove 19 for the docking and positioning of the upper and lower dies.

[0035] Working process: The lower die 2 rises to dock with the upper die 1; the cup male die 7 descends to extrude the plastic sheet until the plastic cup is formed in cooperation with the cup female die 10; the cup male die 7 rises, the lower die 2 descends, and then the ejector block 14 rises to eject the formed plastic cup out of the cup female die 10; the blowing mechanism operates to blow the plastic cup into the collection mechanism.
