Description

Technical Field

[0001] The utility model relates to the technical field of paper pulp moulds, in particular to a split paper pulp mould. Background Art

[0002] Pulp molds are tools used in the production of pulp molded products. Through vacuum or pressure, pulp fibers are evenly distributed on the mold surface, forming a wet paper mold with a predetermined geometry and size. These wet paper molds are then dehydrated, demolded, dried, and shaped into the final pulp molded product.

[0003] Currently, Chinese patent publication number CN221029315U discloses a coffee pulp molding mold comprising an upper mold and a lower mold. The upper mold comprises an upper template and a molding core, while the lower mold comprises a lower template, a molding cavity, and a metal mesh. The molding cavity is formed at the top of the lower template. The metal mesh covers and contacts the inner wall of the molding cavity. The molding core and the molding cavity form a cavity for molding coffee pulp products. The lower template has a positioning groove for the edge of the metal mesh, which has a positioning hole. The edge of the metal mesh is provided with a positioning sleeve that is inserted and snapped into the positioning hole. This utility model effectively positions the metal mesh on the lower template, preventing it from shifting, ensuring a good fit between the metal mesh and the cavity, and resulting in a high yield rate for the molded coffee pulp products.

[0004] However, in actual use, due to the tight fit between the forming core and the metal mesh, the pulp fibers remaining on the lower surface of the forming core or the metal mesh after long-term use are difficult to completely remove, which can easily affect the forming effect of the next cycle. The mold is not convenient for quickly replacing the forming core or the metal mesh, and needs further optimization.

[0005] Therefore, the present application provides a split pulp mold to meet the needs. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a split pulp mold to solve the problem that the existing pulp mold is prone to residual pulp fibers that are difficult to remove after long-term use, which affects the molding effect of the next cycle of products.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0011] Optionally, a disc is fixed on the limiting column, and a return spring is installed on the disc.

[0012] Optionally, one end of the return spring away from the disc is connected to the interior of the lower die base, and the return spring elastically abuts against the disc, causing the end of the limiting column to be inserted into the pressure plate.

[0013] Optionally, a limiting hole for inserting the end of the limiting column is provided on the pressing plate.

[0014] Optionally, a buckle groove is provided on the handle.

[0015] Optionally, a vertical fixing column is fixed to the bottom of the inner side of the shaping protective shell, and the fixing column passes through the middle of the upper mold base.

[0016] Optionally, the top end of the fixing column passes through the middle of the upper end surface of the upper mold base and is fitted with a fastening nut.

[0017] Optionally, a receiving groove for the top end of the fixing column to pass through is opened in the middle of the upper end surface of the upper mold base, and the fastening nut is placed in the receiving groove.

[0018] Optionally, the bottom of the forming groove in the lower mold base is densely covered with downward-facing fine holes and is connected to a drain pipe.
