Adopt the utility model discloses, will press the material ring to set up in edge under the last edge of a knife, make it be slow in last edge of a knife and sheet contact, guaranteed the height on the cup edge of fashioned cup to the pressfitting height of accessible control lower mould controls the high thickness of its cup, makes the whole intensity that has the ideal of fashioned container.

Description

Container forming device capable of easily controlling thickness of cup edge

Technical Field

The utility model relates to a container forming die especially relates to an easily control cup along container forming device of thickness.

Background

In the prior art, in the compression molding process of thermoforming of a plastic cup, a material pressing ring 1 is adopted to press a sheet 2 on a lower knife edge 3, then the sheet is molded and matched with an upper knife edge 4 to punch and shear the cup edge, as shown in fig. 1 and 2, in the process, the material pressing ring is in contact with the sheet before the upper knife edge, and under the action of strong pressure of an upper die, the thickness of the molded cup edge is difficult to control, the thickness of the molded cup edge is generally thin, the edge of the molded cup edge is sharp, the use experience of consumers is not good, and in addition, the integral mechanical strength of the molded cup edge is not ideal due to the fact that the edge of the cup edge is thin.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem that will solve provides a container forming device who easily controls cup along thickness. The thickness of the cup rim can be easily controlled in the forming process.

In order to solve the technical problem, the embodiment of the utility model provides an easily control container forming device of cup along thickness, including last mould, lower mould, pressure material ring, go up the edge of a knife, lower edge of a knife fixed respectively set up in go up on mould, the lower mould, pressure material ring slide set up in go up the edge of a knife inner wall, pressure material ring with go up and be provided with reset spring between the mould, press material ring lower extreme retraction in go up in the edge of a knife.

Wherein the height difference between the lower end of the material pressing ring and the lower end of the upper knife edge is the thickness of the processed sheet reduced by 0.15-0.2 mm.

Implement the embodiment of the utility model provides a, following beneficial effect has: the utility model discloses to press the material ring to set up in edge under the last edge of a knife, make it be slow in last edge of a knife and sheet contact, guaranteed the height on the cup edge of fashioned cup to the pressfitting height of accessible control lower mould controls the thickness of its cup height, makes the whole intensity that has the ideal of fashioned container.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Refer to the schematic structural diagrams shown in fig. 2 and 3.

The utility model discloses easily control container forming device of cup along thickness, including last mould 5, lower mould 6, pressure material ring 1, go up edge of a knife 4, lower edge of a knife 3 and fixed the setting respectively on last mould 5, lower mould 6, press material ring 1 to slide and set up in last edge of a knife 4 inner wall, press the material ring 1 and go up and be provided with reset spring 7 between the mould 5.

In order to avoid the contact between the pressing ring 1 and the sheet 2 before the upper knife edge 4 and prevent the excessive extrusion of the pressing ring 1 on the sheet 2 before the cup edge is formed, so as to cause the extremely thin cup edge, in this embodiment, the lower end of the pressing ring 1 is retracted into the upper knife edge 4.

The height difference of the lower end between the material pressing ring 1 and the upper knife edge 4 is 0.15-0.2 mm reduced by the thickness of the processed sheet, preferably 0.18 mm and 0.2 mm.

For example, when a 2mm sheet is formed, the height difference of the lower end between the pressing ring 1 and the upper knife edge 4 is controlled to be 1.8mm, wherein 0.2mm is reserved for extrusion with the pressing ring 1.

For example, when 3mm sheets are formed, the height difference of the lower end between the pressing ring 1 and the upper knife edge 4 is controlled to be 2.85mm, wherein 0.15mm is reserved for extrusion with the pressing ring 1.

Through the utility model discloses a structure, in the positive and negative pressure thermoforming process about the cup goes on, goes up edge of a knife 4 and the punching shear back of 2 contacts of sheet, presses material ring 1 again with the sheet contact, as shown in fig. 5, has avoided excessive pressing to and the regulation of the compound die height of accessible control lower mould 6, to the thickness on accurate control shaping cup edge.

The above-mentioned embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which should not be construed as limiting the scope of the present invention. All modifications made according to the spirit of the main technical scheme of the present invention shall be covered within the protection scope of the present invention.
