Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of casting equipment, and in particular to a casting-type polyurethane pouring bucket that is easy to clean and use. Background Technology
[0002] In the production process of cast polyurethane, the pouring tank is one of the key pieces of equipment. Currently, the common pouring tank for cast polyurethane involves first weighing the liquid cast polyurethane prepolymer and placing it into the tank. Then, the weighed curing agent and other additives are added according to the formula. After thorough mixing, the tank is lifted manually or by lifting equipment, and the mixed liquid reaction mixture is poured into the mold through the pouring pipe for molding and vulcanization. After pouring, the tank is placed in a hot oven to allow the residual liquid polyurethane in the tank to react and solidify at high temperature before cleaning, thus achieving the recycling of the pouring tank.
[0003] However, existing conventional polyurethane casting hoppers have several problems. When casting liquid mixtures, the short design of the casting pipe makes it difficult to reach the inner part of the mold, resulting in uneven distribution of the liquid material poured into the inner part of the mold, affecting the thickness and appearance of the final product. Furthermore, the inner wall of conventional casting hoppers is mostly made of stainless steel, and residual polyurethane material inside the hopper tends to stick to the inside after high-temperature curing in the oven, making cleaning difficult. If the casting pipe is designed to be too long, residual material at the corners of the hopper and casting pipe becomes difficult to clean, affecting production efficiency, and the metal casting pipe can easily scratch the mold. Utility Model Content
[0004] In view of the aforementioned problems with existing pouring buckets, the aim is to provide a pouring polyurethane pouring bucket that is easy to clean and use.
[0005] The specific technical solution is as follows: A pouring polyurethane pouring bucket that is easy to clean and use includes a bucket body, a discharge pipe on the bottom side of the bucket body, a valve connected to the discharge pipe, and an extension pipe. The extension pipe is made of plastic and one end of the extension pipe is threaded onto the outside of the discharge end of the discharge pipe. The extension tube includes: A connecting pipe, one end of which has an internal thread on its inner wall, and the discharge end of the discharge pipe has an external thread on its outer wall, which engages with the internal thread. An adjusting tube, one end of which is rotatably sleeved on the outside of the connecting tube and can slide along the axial direction of the connecting tube, and the other end of which is bent downward.
[0006] Furthermore, in a preferred embodiment, an installation groove is formed radially outward on the inner wall of one end of the connecting pipe, the internal thread is provided on the inner wall of the installation groove, and the discharge end of the discharge pipe is matched with the bottom of the installation groove.
[0007] Furthermore, as a preferred embodiment, a sealing gasket is provided between the discharge pipe and the discharge end of the discharge pipe.
[0008] Furthermore, as a preferred embodiment, the outer wall of the other end of the connecting pipe has at least one sealing groove, and a sealing ring is coaxially disposed in the sealing groove, the sealing ring being in a sealing fit with the inner wall of the regulating pipe.
[0009] Furthermore, in a preferred embodiment, two sealing grooves are provided and spaced apart along the axial direction of the connecting pipe, and two sealing rings are provided accordingly.
[0010] Furthermore, as a preferred embodiment, the inner wall of the barrel is coated with a Teflon non-stick layer.

Figure 4 This is a cross-sectional view of the connecting pipe and the discharge pipe of a cast-type polyurethane pouring tank that is easy to clean and use according to this utility model. Figure 1-4 As shown, a preferred embodiment of a pouring polyurethane pouring tank that is easy to clean and use is illustrated. The tank includes a body 1, with a discharge pipe 12 on the bottom side of the body 1. A valve 13 is connected to the discharge pipe 12. The tank also includes an extension pipe 2, which is made of plastic and has one end threaded onto the outside of the discharge end of the discharge pipe 12. The extension pipe 2 includes a connecting pipe 21 and an adjusting pipe 22. One end of the connecting pipe 21 has an internal thread 211 on its inner wall, and the outer wall of the discharge end of the discharge pipe 12 has an external thread 121 that engages with the internal thread 211. One end of the adjusting pipe 22 is rotatably fitted onto the outside of the connecting pipe 21 and can slide along the axial direction of the connecting pipe 21. The other end of the adjusting pipe 22 is bent downwards.
[0021] In this application, quick assembly and disassembly are achieved through the internal thread 211 of the connecting pipe 21 and the external thread 121 of the discharge pipe 12, which facilitates cleaning of residues at the corners of the material pipe. The design of the adjusting pipe 22, which can slide and rotate axially, can flexibly adjust the pouring length to completely cover the inner area of the mold and ensure uniform distribution of polyurethane raw materials. It can also be bent downwards to adapt to different pouring angles. The plastic extension pipe 2 avoids scratching the mold and improves the safety of use.
[0022] To prevent the regulating pipe 22 from moving or rotating during the pouring process, it can be held in place by hand, or the regulating pipe 22 can be fixed by tightening the fixing bolts so that the fixing bolts are pressed against the outer wall of the connecting pipe 21, thereby locking the regulating pipe 22.
[0023] As a further improvement and optimization of this solution, an installation groove 213 is formed radially outward on the inner wall of one end of the connecting pipe 21, and an internal thread 211 is provided on the inner wall of the installation groove 213. The discharge end of the discharge pipe 12 is matched with the bottom of the installation groove 213.
[0024] As a further improvement and optimization of this solution, a sealing gasket is provided between the discharge pipe 12 and the discharge end of the discharge pipe 12. The sealing gasket can effectively prevent liquid from leaking from the connection between the discharge pipe 12 and the connecting pipe 21 during the pouring process, ensuring the cleanliness of the pouring environment, avoiding waste of raw materials, and improving production safety.
[0025] As a further improvement and optimization of this solution, the outer wall of the other end of the connecting pipe 21 has at least one sealing groove 212, and a sealing ring 3 is coaxially arranged in the sealing groove 212. The sealing ring 3 is in a sealing fit with the inner wall of the regulating pipe 22. The fit between the sealing groove 212 and the sealing ring 3 can ensure the sealing between the regulating pipe 22 and the connecting pipe 21, prevent liquid leakage during the sliding process of the regulating pipe 22, ensure the smooth progress of the casting process, and improve the product qualification rate.
[0026] As a further improvement and optimization of this solution, two sealing grooves 212 are provided, spaced apart along the axial direction of the connecting pipe 21, and two sealing rings 3 are provided accordingly. The two sealing grooves 212 and sealing rings 3 further enhance the sealing effect between the regulating pipe 22 and the connecting pipe 21, effectively preventing liquid leakage. Especially under conditions of frequent sliding of the regulating pipe 22, it can still maintain good sealing performance, improving the reliability and service life of the equipment.
[0027] As a further improvement and optimization of this solution, the inner wall of barrel 1 is coated with a Teflon non-stick layer. The Teflon non-stick layer allows residual polyurethane material inside the barrel to be easily cleaned away after heating and solidification, greatly reducing the workload of employees.
[0028] As a further improvement and optimization of this solution, extension tube 2 is made of PTFE. PTFE tubing has excellent non-stick properties, further improving the cleaning efficiency of the barrel. At the same time, its material properties ensure that it will not scratch the mold, extending the mold's service life and reducing production costs.
[0029] As a further improvement and optimization of this solution, handles 11 are provided on both sides of the top of the barrel 1 and on the bottom side of the barrel 1 opposite to the discharge pipe 12. The handles 11 facilitate the lifting operation of the lifting device to lift the barrel.
