[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded.

[0003] The patent publication number CN207256821U discloses an extrusion mold, which includes a mold body, a transition plate, a rear support, a front support, a manifold, a die, and a shaping mold connected in sequence. The mold body, the transition plate, the rear support, the front support, and the manifold have manifold cavities inside. The die and the shaping mold are provided with cavities. The die and the shaping mold are provided with docking devices at positions corresponding to the cavities. The docking devices include an annular protrusion provided on the die and an annular recess provided on the shaping mold that docks with the annular protrusion.

[0004] As shown in the above technology, the required products are produced through an extrusion die. In existing extrusion dies, thin-wall extrusion is achieved through the structure of protrusions and forming cavities. After long-term use, friction occurs on the surface of the structure, resulting in the thickness of the produced products not meeting the standards. Therefore, it is necessary to maintain or replace the protrusions in the die. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a honeycomb thin-walled extrusion die that can improve product strength, solving the problem that the internal structure of existing extrusion dies needs to be replaced after long-term use.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A honeycomb thin-walled extrusion mold that can improve product strength includes a mold body, a forming cavity is provided inside the mold body, a buffer box is fixedly connected to the top of the mold body, and a feed port is provided on both sides of the buffer box. A honeycomb thin-walled structure is provided inside the forming cavity and the buffer box, and an elastic component for material stabilization extrusion is provided below the honeycomb thin-walled structure.

[0007] The honeycomb thin-walled structure includes multiple fixing ribs, which are fixed at equal intervals between the left and right sides of the inner wall of the buffer box. Multiple hexagonal socket head caps are inserted at equal intervals at the bottom of the fixing ribs. A flow divider is sleeved on the surface above the fixing rib through the hexagonal socket head caps, and a hexagonal block is threaded to the surface above the flow divider of the hexagonal socket head caps. The multiple hexagonal blocks and the molding cavity form a honeycomb extrusion channel.

[0008] Preferably, the top and bottom of the diversion block are fixedly connected with two left and right positioning blocks, the bottom of the hexagonal block is provided with a first positioning groove corresponding to the two upper positioning blocks, and the top of the fixing rib is provided with a second positioning groove corresponding to the lower positioning block.

[0009] Preferably, the shape of the diverter block is a hexagonal frustum, and the large end of the diverter block has the same dimensions as the end face of the hexagonal block.

[0010] Preferably, a shielding strip is attached to the bottom of the fixing rib to shield the internal hexagon bolt.

[0011] Preferably, both the diverter block and the hexagonal block are made of high-strength alloy steel, and their surfaces are subjected to hard anodizing treatment. The surfaces of the diverter block and the hexagonal block, as well as the inner wall of the forming cavity, are coated with wear-resistant material.

[0012] Preferably, the elastic component includes a base plate, which is fixedly connected to the bottom of the buffer box.

The push plate is located below the feed inlet of the buffer box, and a limiting block is provided on the inner side of the feed inlet to prevent the push plate from going beyond the feed inlet.

[0013] Beneficial effects

[0014] This invention provides a honeycomb-type thin-walled extrusion die that can improve product strength. Compared with the prior art, it has the following advantages:

[0015] 1. This honeycomb thin-walled extrusion die, which can improve product strength, includes multiple fixing ribs in a honeycomb thin-walled structure. These ribs are equidistantly fixed between the left and right sides of the inner wall of the buffer box. Multiple hexagonal bolts are inserted at equal intervals at the bottom of the fixing ribs. The honeycomb thin-walled structure is redesigned, and the hexagonal truncated pyramids are installed using hexagonal bolts, making it easy to replace. Furthermore, the uniform flow of materials is achieved through the cooperation of the flow divider cone, which improves product strength and quality and enhances the practicality of the device during use.

[0016] 2. This honeycomb thin-walled extrusion die, which can improve product strength, includes a base plate as an elastic component. The base plate is fixedly connected to the bottom of the buffer box, and multiple springs are fixedly connected to the top of the base plate. The other end of each spring is fixedly connected to a push plate. By setting the elastic component in the die body, when the product is extruded, the local stress changes. At this time, the cooperation between the springs and the push plate makes the material extruded stably, thereby avoiding the problem of stress concentration and further ensuring product quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The honeycomb thin-walled extrusion die, which can improve product strength, offers two technical solutions:

[0025] The first embodiment includes a mold body 1, a molding cavity 2 is provided inside the mold body 1, a buffer box 3 is fixedly connected to the top of the mold body 1, and a feed port is provided on both sides of the buffer box 3. A honeycomb thin-walled structure 4 is provided inside the molding cavity 2 and the buffer box 3, and an elastic component 5 for material stabilization extrusion is provided below the honeycomb thin-walled structure 4.

[0026] The honeycomb thin-walled structure 4 includes multiple fixing ribs 41, which are equidistantly fixed between the left and right sides of the inner wall of the buffer box 3. Multiple hexagonal socket head cap screws 42 are equidistantly inserted into the bottom of each fixing rib 41. A flow divider block 43 is fitted onto the surface of each hexagonal socket head cap screw 42 above the flow divider block 43. A hexagonal block 44 is threaded onto the surface of each hexagonal socket screw 42 above the flow divider block 43. Multiple hexagonal blocks 44 form a honeycomb extrusion channel with the molding cavity 2. Two positioning blocks 45 are fixedly connected to the top and bottom of each flow divider block 43. The bottom of each hexagonal block 44 has an opening... The first positioning groove 46 corresponds to the two upper positioning blocks 45, and the top of the fixing rib 41 is provided with a second positioning groove corresponding to the lower positioning block 45. The shape of the diversion block 43 is a hexagonal truncated pyramid, and the large end of the diversion block 43 has the same end face size as the hexagonal block 44. A shielding strip 47 is pasted on the bottom of the fixing rib 41 to shield the internal hexagonal bolt 42. Both the diversion block 43 and the hexagonal block 44 are made of high-strength alloy steel, and their surfaces are treated with hard anodizing. The surfaces of the diversion block 43 and the hexagonal block 44 and the inner wall of the forming cavity 2 are coated with wear-resistant material, which can be aluminum oxide.

[0027] The honeycomb thin-walled structure was redesigned, and the hexagonal truncated pyramid 44 was installed with hexagonal socket head cap screws, which facilitated its replacement. Furthermore, the material flow was made uniform through the cooperation of the flow divider block 43, which improved the product strength and quality and enhanced the practicality of the device during use.

[0028] The second embodiment differs from the first embodiment in that the elastic component 5 includes a base plate 51, which is fixedly connected to the bottom of the buffer box 3. Multiple springs 52 are fixedly connected to the top of the base plate 51 in an array. The other end of each spring 52 is fixedly connected to a push plate 53, which contacts the inner wall of the buffer box 3 and is sealed by a sealing strip. The push plate 53 is located below the feed inlet of the buffer box 3, and a limiting block is provided on the inner side of the feed inlet to prevent the push plate 53 from going beyond the feed inlet.

[0029] An elastic component 5 is installed in the mold body. When the product is extruded, the local stress changes. At this time, the material is stably extruded through the cooperation of the spring 52 and the push plate 53, thereby avoiding the problem of stress concentration and further ensuring product quality.

[0030] In use, the material enters above the push plate 53 and is diverted into the extrusion channel by the diverting block 43, thus completing the honeycomb thin-wall extrusion. During extrusion, the product enters the outside of the mold body 1 and is cooled. At this time, the spring 52 assists in the extrusion, thus avoiding the problem of stress concentration. In addition, when assembling the honeycomb thin-wall structure 4, the hexagon socket head cap screw 42 is inserted into the fixing rib 41, and the diverting block 43 is fitted onto the outside of the hexagon socket head cap screw 42. The positioning block 45 on the small end of the diverting block 43 is aligned with the second positioning block on the fixing rib 41 and inserted. Then, the first positioning groove 46 on the hexagonal block 44 is aligned with the positioning block 45 on the large end of the diverting block 43 and inserted. Then, the hexagon socket head cap screw 42 is rotated so that the hexagon socket head cap screw 42 is screwed into the interior of the hexagonal block 44, thus completing the assembly. Finally, the shielding strip 47 is attached to the bottom of the fixing rib 41.
