Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding, in particular to a mold structure for tidying up waste edges of pulp molding products. Background Art

[0002] Existing pulp molding products will have an extra portion of waste edges during the production process, resulting in a waste of pulp. For multi-cavity molds, the existing technology generally processes the core and the base plate separately, which not only reduces the risk of one-piece processing but also reduces maintenance costs. However, even if the core and the base plate have been processed separately, in large molds, due to the large mold span, this leads to very high requirements for the position matching accuracy of the core and the base plate, otherwise there will be cumulative errors, making the mold unusable. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies of the prior art, the utility model provides a mold structure for neatly trimming waste edges of pulp molded products, thereby solving the problems raised in the above-mentioned background technology.

[0005] (II) Technical solution

[0006] To achieve the above purpose, the utility model is implemented through the following technical scheme: a mold structure for neatly trimming waste edges of pulp molded products, including a slurry suction mold bottom frame and an extrusion mold, wherein a mold core mounting groove is provided inside the slurry suction mold bottom frame, a slurry suction mold core bottom frame is installed above the mold core mounting groove, a slurry suction convex mold core is installed above the slurry suction mold core bottom frame, a slurry suction net is sleeved on the outer surfaces of the slurry suction convex mold core and the slurry suction mold core bottom frame, a screen pressing frame is installed above the slurry suction mold bottom frame, a concave mold cavity is provided below the extrusion mold, and an avoidance groove is arranged around the concave mold cavity.

[0007] Preferably, a positioning block is provided above the periphery of the mold core installation groove, a positioning groove is provided below the periphery of the slurry suction mold core bottom frame, and the assembly of the slurry suction mold core bottom frame and the slurry suction mold bottom frame is positioned by the positioning block and the positioning groove.

[0008] Preferably, a profiling groove is provided inside the bottom frame of the slurry suction mold core, a screw through hole is provided below the profiling groove, and the slurry suction convex mold core is inserted into the profiling groove and fixedly connected with the bottom frame of the slurry suction mold core by screws.

[0009] Preferably, the screen pressing frame is fixedly connected to the bottom frame of the slurry suction mold by screws, and the screen pressing frame presses and fixes the bottom frame of the slurry suction mold core and the slurry suction screen together above the mold core mounting groove.

[0010] Preferably, the height of the upper surface of the screen pressing frame is higher than that of the adjacent slurry absorbing net, which can block the slurry absorbing beyond the waste edge area, so that the area outside the waste edge of the slurry absorbing net cannot absorb slurry, thereby reducing the enlargement of the product waste edge and saving slurry.

[0011] Preferably, when the bottom frame of the slurry suction mold is molded with the extrusion mold, the screen pressing frame is embedded in the avoidance groove to avoid interference between the screen pressing frame and the bottom frame of the slurry suction mold and the extrusion mold.

[0012] The utility model provides a mold structure for neatly trimming waste edges of pulp molding products, which has the following beneficial effects:

[0013] 1. The mold structure of the pulp molded product with neat waste edges has the effect of reducing waste edges and saving pulp by setting a pressure screen frame. By increasing the height of the high-pressure screen frame, the area outside the waste edge of the slurry suction net cannot absorb slurry, thereby reducing the enlargement of the product waste edge and saving slurry.

[0014] 2. The mold structure for neatly trimming the waste edges of the pulp molded product has the effect of fine-tuning the relative position of the mold core and the bottom plate through the coordinated arrangement of the slurry suction mold bottom frame, the slurry suction mold core bottom frame and the slurry suction convex mold core, thereby reducing the processing accuracy and facilitating maintenance. A slurry suction mold core bottom frame is added between the slurry suction mold bottom frame and the slurry suction convex mold core as a transition structure. The slurry suction mold core bottom frame and the slurry suction mold bottom frame can be quickly replaced to improve the disassembly and assembly efficiency for easy maintenance. The slurry suction convex mold core and the slurry suction mold core bottom frame are fixed by adjusting the relative position of the two to adjust the position of the slurry suction convex mold core installed on the slurry suction mold bottom frame. Since the relative position is adjustable, even if the processing accuracy deviates, it can be corrected to achieve normal use. Since the processing accuracy requirement is reduced, the processing cost can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 6 The utility model provides a technical solution: a mold structure for neatly trimming waste edges of pulp molding products, comprising a pulp suction mold bottom frame 1 and an extrusion mold 2, wherein the extrusion mold 2 is fixedly mounted above the pulp suction mold bottom frame 1, and the pulp suction mold bottom frame 1 reciprocates up and down, and when the pulp suction mold bottom frame 1 moves downward, it is immersed in pulp to absorb pulp, and when the pulp suction mold bottom frame 1 moves upward, it is molded with the extrusion mold 2, and a core mounting groove 101 is provided inside the pulp suction mold bottom frame 1, and a pulp suction mold core bottom frame 3 is mounted above the core mounting groove 101, A positioning block 102 is arranged above the periphery of the mold core installation groove 101, a positioning groove 301 is provided below the periphery of the slurry suction mold core bottom frame 3, the assembly of the slurry suction mold core bottom frame 3 and the slurry suction mold bottom frame 1 is positioned by the positioning block 102 and the positioning groove 301, a slurry suction convex mold core 4 is installed above the slurry suction mold core bottom frame 3, a profiling groove 302 is provided inside the slurry suction mold core bottom frame 3, a screw through hole 203 is provided below the profiling groove 302, and the slurry suction convex mold core 4 is inserted into the profiling groove 302 and is screwed to the slurry suction mold core The bottom frame 3 is fixedly connected, and the slurry suction mold core bottom frame 3 serves as a transition structure connecting the slurry suction mold bottom frame 1 and the slurry suction mold core bottom frame 3, which can not only realize the quick replacement of the slurry suction mold core bottom frame 3 to reduce the maintenance cost but also reduce the production cost of the mold. The outer surface of the slurry suction convex mold core 4 and the slurry suction mold core bottom frame 3 is sleeved with a slurry suction net 5, and a pressing net frame 6 is installed above the slurry suction mold bottom frame 1. The pressing net frame 6 is fixedly connected to the slurry suction mold bottom frame 1 by screws, and the pressing net frame 6 presses the slurry suction mold core bottom frame 3 and the slurry suction net 5 together and fixes them on the mold core installation Above the groove 101, the height of the upper surface of the screen pressing frame 6 is higher than the height of the adjacent slurry absorption net 5, which can block the slurry absorption beyond the waste edge area, so that the area outside the waste edge of the slurry absorption net 5 cannot absorb slurry, thereby reducing the enlargement of the product waste edge and saving slurry. A concave die cavity 201 is opened below the extrusion die 2, and an avoidance groove 202 is arranged around the concave die cavity 201. When the slurry absorption mold bottom frame 1 and the extrusion die 2 are molded together, the screen pressing frame 6 is embedded in the avoidance groove 202 to avoid interference between the screen pressing frame 6 and the slurry absorption mold bottom frame 1 and the extrusion die 2.

[0024] When in use, first embed the suction mold core bottom frames 3 into the mold core installation grooves 101 one by one, and then mark the matching suction mold core bottom frames 3 and the mold core installation grooves 101, that is, a suction mold core bottom frame 3 can be smoothly inserted into a mold core installation groove 101 and will not shake due to the limitation of the positioning block 102 and the positioning groove 301, and further connect the suction convex mold core 4 to the suction mold core bottom frame 3 in advance by screws but do not lock them, and further install the suction convex mold core 4 on the suction mold bottom frame 1 through the suction mold core bottom frame 3, and further install the screen pressing frame 6 to fix all the suction mold core bottom frames 3. At this time, since the screws for installing the suction convex mold core 4 are not locked, the suction convex mold core 4 can be moved in a small range, and further use an external device to correct the relative position of the suction convex mold core 4 and the suction mold bottom frame 1 Position and lock the screws. The external device can be a matching extrusion die 2 or an auxiliary positioning tool. This adjustment process can compensate for the processing error to achieve precise positioning, and then the processing accuracy of each component can be reduced to achieve cost savings. After that, the slurry suction punch core 4 and the slurry suction core bottom frame 3 are locked into a whole. Then the maintenance of the slurry suction punch core 4 and the maintenance of the slurry suction net 5 are both achieved through the quick-change function of the slurry suction core bottom frame 3 and the slurry suction mold bottom frame 1. Quick disassembly and assembly are achieved. When the mold is closed, since the height of the screen pressing frame 6 is higher than the height of the waste edge forming of the slurry suction net 5, the area outside the waste edge of the slurry suction net 5 cannot absorb slurry, thereby reducing the waste edge of the product and saving slurry. In this process, since the waste edge is bounded by the slot hole of the screen pressing frame 6, no excess waste edge is produced outward at will, and thus the waste edge of the produced product is neat and easy to trim.

[0025] In summary, the mold structure for neat waste edges of pulp molded products increases the height of the high-pressure mesh frame 6 so that the area outside the waste edge of the slurry suction net 5 cannot absorb slurry, thereby reducing the enlargement of the product waste edge and saving slurry. A slurry suction mold core bottom frame 3 is added between the slurry suction mold bottom frame 1 and the slurry suction convex mold core 4 as a transition structure. The slurry suction mold core bottom frame 3 and the slurry suction mold bottom frame 1 can be quickly replaced to improve the disassembly and assembly efficiency for easy maintenance. The slurry suction convex mold core 4 and the slurry suction mold core bottom frame 3 are fixed by adjusting the relative position of the two to adjust the position of the slurry suction convex mold core 4 installed on the slurry suction mold bottom frame 1. Since the relative position is adjustable, even if there is a deviation in the processing accuracy, it can be corrected to achieve normal use. Since the processing accuracy requirement is reduced, the processing cost can also be reduced.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
