Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, specifically a honeycomb extrusion die that can reduce clogging. Background Technology

[0002] Honeycomb catalysts are mainly manufactured by extrusion using an extrusion die. Referring to the patented patent CN214821166U, an arc-shaped honeycomb denitrification catalyst extrusion die includes a core, a frame, positioning components, and fixing components. One side of the core has a mud-passing hole, and the other side has a limiting post. An extrusion groove connected to the mud-passing hole is formed between any two adjacent limiting posts, reducing the velocity difference of flue gas within the channels and lowering the risk of catalyst blockage. As described in the aforementioned patent, when using existing honeycomb extrusion dies that reduce blockage, it is often difficult to position the frame on the outside of the core end and prevent it from detaching during the frame installation process. This can easily lead to installation efficiency being affected by the frame loosening and shifting during subsequent installation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a honeycomb extrusion die that reduces clogging and solves problems such as installation efficiency being affected by die frame misalignment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a honeycomb extrusion mold that reduces clogging, comprising a mounting plate, wherein the mounting plate is connected to an extruder for honeycomb extrusion of materials, the extruder comprising:

[0005] Several first screws, threadedly connected to the edge of the mounting plate, are used to secure the mounting plate.

[0006] A mold core assembly is mounted on a mounting plate for material forming.

Several conical holes are provided at the upper end of the upper side of the mounting plate corresponding to the mud inlet holes. Extrusion grooves communicating with the conical holes are provided between the several forming blocks.

[0007] A mold frame assembly is mounted on a mounting plate to assist the forming blocks in promoting the forming of extruded materials. The mold frame assembly includes a mold frame body that is slidably connected to an array of positioning rods and abuts against the upper side of the mounting plate. The upper side of the mold frame body is provided with several mounting grooves that are threadedly connected to several second screws. The edge of the mold frame body is provided with an array of positioning grooves that are slidably connected to the positioning rods. A forming groove is provided in the middle of the mold frame body near the outer side of several forming blocks.

[0008] Preferably, the upper side of the positioning rod near the nut end is threaded, and the bottom of the nut is in contact with the upper end of the mold frame body.

[0009] Preferably, the molding block has rounded corners near the center of the mounting plate, and the mold core assembly also includes a cap that is snapped onto the upper side of the mounting groove, with a rubber pad fitted on the lower side of the cap.

[0013] Beneficial effects

[0014] This invention provides a honeycomb extrusion die that can reduce clogging. Compared with the prior art, it has the following advantages:

[0015] 1. This honeycomb extrusion die, which can reduce clogging, has a positioning rod and nut inside the device. The positioning rod and nut cooperate to facilitate the positioning of the die frame body on the mounting plate through the positioning groove. This helps to fix the die frame body to the outside of several forming blocks on the mounting plate with the second screw, preventing the subsequent installation operation from being affected by the displacement of the die frame body. The cap plug protects the mounting groove and prevents material from splashing into the mounting groove during the extrusion process.

[0016] 2. This honeycomb extrusion die, which can reduce clogging, reduces the internal pressure of the die by setting a conical groove and rounded corners inside the device, adjusting the angle of the conical hole from 110 degrees to 90 degrees, and lengthening the feed and discharge transition section by 1 mm. The rounded corners on the forming block play an anti-clogging role, thereby reducing material clogging. Attached Figure Description

[0025] The mold frame assembly 4 is mounted on the mounting plate 1 to assist the forming blocks 34 in promoting the forming of extruded materials. The mold frame assembly 4 includes a mold frame body 41 that is slidably connected to an array of positioning rods 31 and fits against the upper side of the mounting plate 1. The upper side of the mold frame body 41 is provided with a plurality of mounting grooves 42 that are threadedly connected to a plurality of second screws 33. The edge of the mold frame body 41 is provided with an array of positioning grooves 43 that are slidably connected to the positioning rods 31. The middle part of the mold frame body 41 is provided with a forming groove 44 near the outer side of a plurality of forming blocks 34. The upper side of the positioning rods 31 is provided with threads near the end of the nut 32, and the bottom of the nut 32 fits against the upper end of the mold frame body 41. The mold core assembly 3 also includes a cap 35 that is snapped onto the upper side of the mounting groove 42, and a rubber pad is fitted on the lower side of the cap 35.
