Technical Field

[0001] The utility model relates to the field of pulp molding processing, in particular to a pulp molding mold with a protective structure. Background Art

[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material to shape paper products into a certain shape using special molds on a molding machine. Depending on the structural shape, the shapes of the upper and lower molds are also different. The upper and lower molds can be replaced, so the downward stroke of the pressing component is also different each time. This can easily lead to long-term impact on the upper and lower molds, resulting in reduced precision and easy deformation. Therefore, a buffer structure needs to be designed.

[0003] Therefore, the existing pulp molding process field needs to be further improved. Utility Model Content

[0004] The purpose of the utility model is to provide a pulp molding die with a protective structure, which can adjust the height of the buffer structure according to the pressing stroke of the pressing component to reduce the impact force.

[0005] In order to achieve the above purpose, the present invention adopts the following scheme:

[0006] A pulp molding die with a protective structure comprises a base and a heated pressing assembly, wherein the base is provided with an adjustable height buffer structure and a height fixing structure for fixing the height of the adjustable height buffer structure.

[0007] Furthermore, the heating and pressing assembly includes a plurality of vertical guide columns arranged on the base, a heating assembly is arranged on the upper ends of the plurality of vertical guide columns, a pressing mechanism is arranged on the heating assembly, and a pressing template is arranged on the pressing mechanism.

[0008] Furthermore, a replaceable mold is provided on the base.

[0009] Furthermore, the adjustable height buffer structure includes an annular pad sleeved on the vertical guide column, and a synchronous connecting rod is provided between two adjacent annular pads.

[0010] Furthermore, the annular pad is made of rubber material.

[0011] Furthermore, the height fixing structure includes an external thread provided on the circumferential outer wall of the vertical guide column, and an adjusting screw sleeve threadably connected to the external thread is sleeved on the vertical guide column.

[0012] Furthermore, the adjusting screw sleeve is arranged below the annular pad.

[0013] In summary, the present invention has the following beneficial effects compared to the prior art:

[0014] The utility model solves the shortcomings existing in the existing pulp molding processing field. Through the structural setting of the utility model, it has the following advantages: the height of multiple buffer structures is adjusted according to the required downward stroke of the downward pressing component, and the impact force between the upper and lower molds is reduced when the mold is closed, the life of the mold is improved, and the processing accuracy is guaranteed. At the same time, the buffer height can be adjusted according to different molds, the adaptability is better, and the structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
