Description

Technical Field

[0001] The utility model relates to the technical field of rotational molding molds, in particular to a rotational molding mold feeding device. Background Art

[0002] Roto-molding refers to the process of delivering raw materials into a mold, and then rotating or shaking the mold to allow the raw materials to evenly cover the inner wall of the mold due to gravity flowability. At the same time, the inner wall is heated during the rotation or shaking of the mold to fuse the raw materials into a flowable state.

[0003] However, when raw materials are conveyed into the existing mold, the raw materials can easily adhere to the inner wall of the feed pipe, causing the fluidity of the feed pipe to deteriorate and become easily blocked. At the same time, because the interior of the feed pipe is relatively narrow, it is difficult to touch the deep inner wall, making it difficult to clean. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding device for a rotational molding mold, which solves the problem that the feeding tube of the rotational molding mold is difficult to access and observe due to its narrow interior, making it difficult to clean the raw materials attached to the inner wall and easily causing blockage that affects the fluidity.

[0021] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] The following combination Figures 1 to 4 The utility model is described in detail.

[0023] A rotational molding mold feeding device includes a base 1, a bracket 101 is provided on the top of the base 1, a mounting plate 102 is provided near one side of the top of the base 1, a mounting frame 103 is provided on one side of the mounting plate 102, a mold 2 is connected to the bracket 101, one end of the mold 2 is connected to the mounting frame 103, and the end of the mold 2 away from the mounting frame 103 is connected to the feeding pipe 3, a connecting cylinder 301 is provided in the middle of the feeding pipe 3, one side of the connecting cylinder 301 is connected to the combined cylinder 302, the side walls of the connecting cylinder 301 and the combined cylinder 302 are provided with a threaded layer 3012, the threaded layer 3012 is matched with the inner wall thread of the feeding pipe 3, and the mold 2 is connected to the motor transmission on one side of the mounting plate 102.

[0024] First, the rotational molding raw material is fed into the mold 2 from the feed pipe 3, and then closed by the valve. At the same time, the motor on the mounting plate 102 starts to operate, driving the mold 2 to rotate to rotationally mold the raw material inside. At the same time, the mold 2 is connected through the mounting frame 103 to make it more stable when rotating, and the bottom is supported by the bracket 101 to keep the mold 2 balanced on one side.

[0025] Furthermore, the connecting cylinder 301 and the combined cylinder 302 are two semi-cylinders that can cooperate with each other, and the cylinder formed by the connecting cylinder 301 and the combined cylinder 302 cooperates with the inside of the feed pipe 3. The connecting cylinder 301 also includes a push ring 3011, a slide groove 3013 and a force block 3014. The push ring 3011 is arranged on one side of one end of the connecting cylinder 301. The slide groove 3013 is a rectangular groove on one side of the connecting cylinder 301. The force block 3014 is a square protrusion on the end of the connecting cylinder 301 away from the push ring 3011. The combined cylinder 302 also includes a slider 3021. The slider 3021 is a rectangular protrusion arranged on one side of the combined cylinder 302. The slider 3021 cooperates with the slide groove 3013.

[0026] When the rotationally molded raw materials are fed into the feed pipe 3, some of the raw materials will adhere to the inner wall of the pipe, causing the fluidity of the feed pipe 3 to deteriorate and become easily blocked. Therefore, a connecting cylinder 301 and a combination cylinder 302 are connected to the inner wall of the feed pipe 3 to replace the contact with the rotationally molded raw materials. Therefore, when the rotationally molded raw materials adhere to the inner walls of the connecting cylinder 301 and the combination cylinder 302, the force blocks 3014 on the connecting cylinder 301 and the combination cylinder 302 are controlled and pressure is applied to allow the combined connecting cylinder 301 and the combination cylinder 302 to rotate. During rotation, because the threaded layer 3012 on the side wall matches the thread on the inner wall of the feed pipe 3, the combined connecting cylinder 301 and the combination cylinder 302 will move along the inner wall of the feed pipe 3 when rotating, thereby removing the feed pipe 3, so as to facilitate the cleaning of the connecting cylinder 301 and the combination cylinder 302, without being difficult to clean due to the angle and position restrictions of the feed pipe 3.

[0027] At the same time, after the connecting tube 301 and the combination tube 302 are moved out of the feed tube 3, the combination tube 302 is pulled so that the slider 3021 on one side moves along the slide groove 3013 on one side of the connecting tube 301, so that the combination tube 302 is separated from the connecting tube 301, thereby facilitating the cleaning of the inner walls of the combination tube 302 and the connecting tube 301, and it will not be difficult to clean them because the interior between the combination tube 302 and the connecting tube 301 is narrow.

[0028] Furthermore, the butt ring 3011 is a semicircular ring-shaped protrusion on one side of one end of the connecting tube 301, and the butt ring 3011 is matched with one end of the combined tube 302.

[0029] When the combination tube 302 is combined with the connecting tube 301 , one end of the combination tube 302 will abut against the butt ring 3011 to ensure that the combination tube 302 and the connecting tube 301 can be aligned when combined without causing height error.

[0030] The following is a specific implementation process of the present invention. First, the rotational molding raw material is transported into the mold 2 from the feed pipe 3, and then closed through the valve. At the same time, the motor on the mounting plate 102 starts to operate, driving the mold 2 to rotate to rotationally mold the raw material inside. At the same time, the mold 2 is connected through the mounting frame 103 to make it more stable when rotating, and the bottom is supported by the bracket 101 to keep the mold 2 balanced on one side. When the rotational molding raw material is fed into the feed pipe 3, some of the raw material will adhere to the inner wall of the pipe, causing the fluidity of the feed pipe 3 to deteriorate and easily become blocked. Therefore, a connecting cylinder 301 and a combination cylinder 302 are connected to the inner wall of the feed pipe 3 to replace the contact with the rotational molding raw material. Therefore, when the rotational molding raw material adheres to the inner walls of the connecting cylinder 301 and the combination cylinder 302, the force blocks 3014 on the connecting cylinder 301 and the combination cylinder 302 are controlled and pressure is applied to allow the combination to be combined. The connecting cylinder 301 and the combination cylinder 302 will rotate, and during rotation, because the threaded layer 3012 on the side wall matches the thread on the inner wall of the feeding tube 3, the combined connecting cylinder 301 and the combination cylinder 302 will move along the inner wall of the feeding tube 3 when they rotate, thereby moving out of the feeding tube 3, so as to facilitate cleaning of the connecting cylinder 301 and the combination cylinder 302, without being difficult to clean due to the angle and position restrictions of the feeding tube 3. At the same time, after the connecting cylinder 301 and the combination cylinder 302 are moved out of the feeding tube 3, by pulling the combination cylinder 302, the slider 3021 on one side will move along the slide groove 3013 on the side of the connecting cylinder 301, so that the combination cylinder 302 will be separated from the connecting cylinder 301, thereby facilitating cleaning of the inner wall of the combination cylinder 302 and the connecting cylinder 301, without being difficult to clean due to the narrow interior between the combination cylinder 302 and the connecting cylinder 301.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
