It is used for external thermal insulation of pipelines and can effectively prevent the penetration of water, moisture and other corrosive liquids and gases. The polyurethane material is injected into the molding mold that matches the shape of the polyurethane shell. The polyurethane material fills the cavity in the molding mold and then solidifies.

The arc-shaped sealing plate 33 and the front-end mesh plate 34 move outward in turn to allow the injection molding material to impact inside the injection molding cavity. The front-end mesh plate 34 moves inside the injection molding material to capture and intercept bubbles. The captured bubbles are moved out of the injection molding material along with the front-end mesh plate 34 to deal with the bubbles existing in the injection molding material; a gap filling and trimming module 4 is provided inside the tube shell shaping module 2. The gap filling and trimming module 4 includes a profiling and supplementing shell 41, a profiling upper plate 42, a profiling lower plate 43 and a trimming shell 44. The profiling upper plate 42 and the profiling lower plate 43 are positioned one above and one below on the inner side of the profiling and supplementing shell 41. The profiling upper plate 42 and the profiling lower plate 43 guide the inner movable module 3 to move horizontally as a whole inside the tube shell shaping module 2. The trimming shell 44 moves at the front end of the profiling and supplementing shell 41 to trim the surface of the polyurethane tube shell passing through.

[0022] The tube shell shaping module 2 provides a molding space for the polyurethane tube shell. The tube shell shaping module 2 is composed of a lower mold base 21 and an upper mold base 22. The two upper mold bases 22 are molded on the top of the lower mold base 21, one on the left and one on the right, so as to facilitate the combination of the two upper mold bases 22 and the lower mold base 21. The profiling part of the upper mold base 22 rotates on the top of the lower mold base 21, and the free ends of the profiling parts of the two upper mold bases 22 are snap-connected, so that after the two upper mold bases 22 are molded to the bottom of the lower mold base 21, the profiling part can be effectively rotated on the top of the lower mold base 21, so that the profiling parts of the two upper mold bases 22 are clamped and spliced ​​together, and are tightly molded on the top of the lower mold base 21 to form a complete polyurethane tube shell injection cavity. The injection molding tube 1 is inserted into the contoured parts of the two upper mold seats 22, so that the injection molding tube 1 is connected to the tube shell shaping module 2, so that the injection material can be effectively injected into the polyurethane tube shell injection molding cavity in the tube shell shaping module 2 through the injection molding tube 1, and the polyurethane tube shell is injection molded inside the tube shell shaping module 2.

[0023] The inner movable module 3 is used to splice the gap filling and trimming module 4, and the inner movable module 3 can enter the lower mold base 21 together with the gap filling and trimming module 4. The inner movable module 3 is composed of an arc mesh partition 31, a docking cross plate 32, an arc sealing plate 33 and a front end mesh plate 34. The docking cross plate 32 is fixedly connected to the high end of the arc mesh partition 31, and the front end mesh plate 34 is fixedly connected to the front end of the docking cross plate 32. The front end mesh plate 34 is stably combined at the front end of the docking cross plate 32 and the arc mesh partition 31 to ensure that the inner movable module 3 as a whole can be stably positioned inside the injection cavity in the tube shell shaping module 2, and move smoothly inside the injection cavity. The arc sealing plate 33 is slidably connected to the inner side wall of the arc mesh partition 31, so that the arc sealing plate 33 can move horizontally on the inner side of the arc mesh partition 31 against the inner side wall of the arc mesh partition 31, and the position of the arc sealing plate 33 is stably adjusted to expose or close the arc sealing plate 33. The arc-shaped sealing plate 33 is positioned on the inner side of the arc-shaped mesh partition 31 and aligned with the arc-shaped mesh partition 31, so that the arc-shaped sealing plate 33 and the arc-shaped mesh partition 31 can cooperate to separate the internal space of the injection molding cavity, and the injection plastic injected through the injection molding tube 1 enters the upper half of the injection molding cavity, effectively separating the injection plastic. The front end mesh plate 34 can move horizontally inside the injection molding cavity driven by the arc-shaped mesh partition 31, and the arc-shaped sealing plate 33 and the front end mesh plate 34 move outward in turn to allow the injection plastic to impact inside the injection molding cavity, effectively mixing the injection plastics that enter successively. The front end mesh plate 34 covers the cross-sectional area of ​​the injection molding cavity, so that the front end mesh plate 34 moves inside the injection plastic, and the front end mesh plate 34 captures and intercepts bubbles through the mesh when passing through the injection plastic, so as to process the bubbles from inside the injection plastic. The inner wall of the lower mold base 21 is provided with a docking groove 212 corresponding to the front end mesh plate 34. The front end mesh plate 34 is snap-connected inside the docking groove 212. The front end mesh plate 34 is flush with the inner wall of the lower mold base 21, and plays the role of docking the front end mesh plate 34, thereby achieving the effect of assisting the positioning of the inner movable module 3 in the tube shell shaping module 2.

[0024] The gap filling and finishing module 4 is composed of a profiling supplement shell 41, a profiling upper plate 42, a profiling lower plate 43 and a finishing shell 44. The profiling upper plate 42 and the profiling lower plate 43 are positioned one above the other on the inner side of the profiling supplement shell 41, and the profiling upper plate 42 and the profiling lower plate 43 are both slidably connected to the inner wall of the profiling supplement shell 41. The profiling upper plate 42 and the profiling lower plate 43 are squeezed from above by two upper die seats 22, and the lower die seat 21 supports the profiling lower plate 43 and the profiling upper plate 42 from below, so as to play the role of positioning the profiling upper plate 42 and the profiling lower plate 43 at the designated position of the rear end of the tube shell shaping module 2. The profiling upper plate 42 and the profiling lower plate 43 are positioned at the designated position of the rear end of the tube shell shaping module 2, so that the profiling supplement shell 41 can be guided by the profiling upper plate 42 and the profiling lower plate 43 to move horizontally on the outer side of the profiling upper plate 42 and the profiling lower plate 43. The profiling supplement shell 41 and the trimming shell 44 are both connected to the inner side of the tube shell shaping module 2, so that the profiling supplement shell 41 and the trimming shell 44 can stably move horizontally inside the tube shell shaping module 2, effectively changing the positions of the profiling supplement shell 41 and the trimming shell 44, and the trimming shell 44 can be separated from the profiling supplement shell 41 from the front end of the profiling supplement shell 41, so that the trimming shell 44 and the profiling supplement shell 41 can independently perform position adjustment operations. The profiling supplement shell 41 is aligned to the inside of the injection molding cavity, and can make up for the extra space between the trimming shell 44 and the tube shell shaping module 2, so as to ensure that the subsequent injection molding of the polyurethane tube shell will not have a thickened surface. The size of the profiling supplement shell 41 and the trimming shell 44 is larger than the front mesh plate 34, so as to ensure that the front mesh plate 34 can smoothly enter the profiling supplement shell 41 and the trimming shell 44, and move horizontally inside the profiling supplement shell 41 and the trimming shell 44, so as to effectively adjust the position of the inner movable module 3 to process the injection molding material from the inside of the injection molding material. The arc mesh partition 31 and the arc sealing plate 33 are slidably connected between the profiling upper plate 42 and the profiling lower plate 43, and the side of the docking cross plate 32 away from the arc mesh partition 31 is slidably connected to the inner wall of the profiling supplement shell 41, and the lower end of the arc mesh partition 31 is close to the concave part of the inner side of the profiling supplement shell 41, so that the inner movable module 3 can always keep the designated route movement inside the tube shell shaping module 2 under the guidance of the gap filling trimming module 4, so as to stably and effectively adjust the position of the inner movable module 3, and stably process the injection molding material in the injection molding cavity.

[0025] The inner movable module 3 and the gap filling and trimming module 4 can be directly placed into the lower mold base 21 from the top of the lower mold base 21 after being spliced. The two contoured parts on the upper mold base 22, one on the left and one on the right, rotate and close the mold to the top of the lower mold base 21, effectively fixing the inner movable module 3 and the gap filling and trimming module 4 from the outside. The arc-shaped sealing plate 33 and the arc-shaped mesh partition plate 31 separate the internal space of the injection molding cavity to separate the injection plastic, so that the injection plastic is temporarily stored in the upper half of the injection molding cavity. The arc-shaped sealing plate 33 and the front mesh plate 34 move outward in turn to allow the injection plastic to impact inside the injection molding cavity, mix the injection plastic and deal with bubbles from inside the injection plastic, which can effectively perform pre-treatment for cooling and curing of the injection plastic. After the polyurethane tube shell is formed, the contoured supplement shell 41 moves horizontally outward to make way for the trimming shell 44. Both ends of the trimming shell 44 have inclined scraping parts. The trimming shell 44 moves horizontally on the surface of the polyurethane tube shell to trim the surface of the polyurethane tube shell passing by. It can effectively trim the surface bumps and edge burrs of the polyurethane tube shell directly after manufacturing and forming, improve the injection molding production effect and efficiency of the polyurethane tube shell, improve the production quality of the polyurethane tube shell, and ensure the subsequent stable splicing and use of the polyurethane tube shell.

[0026] The front end of the arc-shaped mesh partition plate 31 is fixedly connected to two side plates 35, and the side plates 35 are fixedly connected to guide blocks 36. The outer wall of the lower mold base 21 is provided with two guide grooves 211 corresponding to the guide blocks 36, and the guide blocks 36 are connected in the corresponding guide grooves 211. The guide grooves 211 constrain the positioning of the corresponding guide blocks 36, so that the inner movable module 3 and the gap filling and trimming module 4 cooperate, and after being placed into the injection cavity of the tube shell shaping module 2 from the top of the opened tube shell shaping module 2, the two guide blocks 36 and the two side plates 35 cooperate to pull the inner movable module 3 and the gap filling and trimming module 4 from two directions at the same time through the guide blocks 36 clamped to the inside of the guide grooves 211, which can constrain the inner movable module 3 and the gap filling and trimming module 4 as a whole inside the tube shell shaping module 2, and play the role of positioning and reinforcing the inner movable module 3 and the gap filling and trimming module 4. At the same time, the guide blocks 36 can move in the guide grooves 211 close to the groove wall of the guide grooves 211 to ensure the stability of the inner movable module 3 when it moves horizontally.

[0027] Two operating blocks 441 are fixedly connected to the top of the trimming shell 44. The operating blocks 441 serve as force-applying members for the operator to operate to complete the independent movement of the trimming shell 44. A clearance groove 221 corresponding to the operating block 441 is provided on the upper mold base 22. The operating block 441 is snap-connected inside the corresponding clearance groove 221, so that the contoured part of the upper mold base 22 can be offset from the operating block 441 for rotation.

[0028] The working principle of the present invention is as follows: two upper mold bases 22 are molded on the top of the lower mold base 21, one on the left and one on the right, the profiling part on the upper mold base 22 rotates outward to expose the inner cavity of the lower mold base 21, and the inner movable module 3 and the gap filling and trimming module 4 are directly placed in the lower mold base 21 from the top of the lower mold base 21 after splicing, the profiling parts on the two upper mold bases 22 are rotated and molded to the top of the lower mold base 21, and the inner movable module 3 and the gap filling and trimming module 4 are tightly positioned from the outside, and the injection plastic is injected into the injection molding cavity of the polyurethane shell through the injection molding tube 1, and the arc-shaped sealing plate 33 is connected with the arc-shaped sealing plate 33. The mesh partition 31 divides the internal space of the injection molding cavity to separate the injection plastic, allowing the injection plastic to temporarily store in the upper half of the injection molding cavity. The arc-shaped sealing plate 33 and the front mesh plate 34 move outward in turn to allow the injection plastic to impact inside the injection molding cavity, mix the injection plastic and remove bubbles from inside the injection plastic. The injection plastic is formed inside the injection molding cavity. After the polyurethane tube shell is formed, the contour-matching shell 41 moves horizontally outward to make room for the trimming shell 44. The trimming shell 44 moves horizontally on the surface of the polyurethane tube shell to trim the surface of the polyurethane tube shell that passes by. After the trimming is completed, the polyurethane tube shell is taken out from the lower mold base 21.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
